R Rabbit hair
Used as a component in blends for wool weaving yarns, as a substitute for vicuna to give a soft handle in the fabric. Race
- Narrow channel along which water flows for irrigation. - Narrow pen along which sheep can walk in single file or can be held tightly.
Race board
Part of a loom in from of the reed and below the warp yarns over which the shuttle or rapier passes. Raddle
Coloured chalk used to temporarily mark bales or sheep. Also placed in a harness on a vasectomised ram to detect which ewes are on heat.
Radiant Panel Test
Laboratory testing device for measuring the critical radiant flux (energy) required to ignite a carpet when exposed to a flaming ignition source.
Raddle
Paint or crayon strapped to a ram’s chest to mark the ewes he mates with. It must be a scourable compound. A sheep that is marked in this way is said to be ‘raddled’. The Cumbrian term is ‘ruddy’.
Raddle harness
Harness carried by a ram to hold a raddle stick on the brisket to identified ewes that have been served. Ragg
Coarse wool fibre used in rugged applications such as gloves and hiking socks. Raised board
The shearing board is raised above the level of the rest of the floor of the shearing shed by around 1 metre. A raised board enables the shed hands to collect the shorn fleeces without excessive bending. Doors lead to the catching pen and there are chutes through which the shorn sheep are pushed.
Raising (or Napping)
Process applied to heavy woollen fabric to raise fibres out of the body of the cloth by toothed rollers to form a fluffy surface, or nap.
Rake
An array of toothed bars which move in a cyclic path to gentling move a floating layer of wool across the surface of a scouring bowl. (See Harrows, Appendix 8)
Ram
Mature male sheep that has not been castrated. Also called a tup in UK and a buck in USA. A flock ram is a non-pedigree ram used in a commercial flock while a stud ram is a pedigree (registered) ram.
Ram effect
The ram effect is when non-cycling ewes are stimulated to ovulate by the sudden introduction of a ram or "teaser." Rams produce a chemical substance called a pheromone, the smell of which stimulates the onset of oestrus. When ewes and rams are in constant contact (sight or smell), the pheromones are much less effective at inducing oestrus.
Ram harness
A device strapped onto the shoulder area of the ram to monitor joining activity in a flock, to draft ewes into early and late lambing groups, or to establish if an individual ram is working. It incorporates a coloured crayon held against the brisket of the ram which leaves a mark on the rump of the recipient, thereby indicating whether a ewe has been serviced by a ram.
Ram stag
Male sheep castrated after maturity. Rambouillet
Large-bodied Merino sheep common in USA, developed in France from animals imported from Spain in 1786. It is a hardy sheep producing good mutton and fine quality wool. All Merino type sheep in USA are Rambouillet or Rambouillet cross (eg, Targee, Columbia, Polypay). There are no Rambouillet sheep in New Zealand and none have entered Australia in recent years.
Random mating
Mating system where all ewes have the same chance of being mated to any ram used.
Rangy Very long body, as opposed to a compact body.

Rapier Metal rod for carrying the weft yarn across a high speed weaving loom. The rapier may be a rigid rod, a telescopic rod or a flexible ribbon. A rapier loom may have a single rapier, or two rapiers operating in unison from opposite sides of the machine. (See Weft Insertion, Loom)
Rate of genetic improvement
This depends on:
1. Number of traits being selected at one time;
2. Heritability of the traits
3. Genetic correlations between the traits selected
4. Selection differentials
5. General interval in the flock.
The rate of improvement is usually expressed per year.
Ratine Originally a thick woollen fabric with a curled nap. Now applied to a fabric made from a range of fibres and which has a rough surface.
Raw wool
A broad term which includes greasy wool or wool which has been scoured, carbonised, washed or solvent degreased; scoured skin wools; washed skin wools; and slipe wools. It consists of wool fibre together with variable amounts of vegetable matter and extraneous alkali insoluble impurities, mineral matter, wool waxes, suint and moisture. Raw wool has not been through a yarn or felt-making process.
Reactive dye
Class of dye widely used on wool and other protein fibres (see Appendix 30) Receipt date
Date on which a farm consignment of wool arrives at a broker’s store. Receiving yard
The very large yard which are first driven into when brought to the sheep yards. Recessive genes
Recessive genes only affect the phenotype when present in a homozygous condition. Hence the recessive gene must be received from both parents before the recessive phenotype will be observed.
Reclassing
In-store pre-sale classing of a grower's fleece wool clip into lines within the same clip. The resulting main lines are offered for sale under the grower's own brand. The wool will not have been carefully sorted according to type at shearing time. Wool brokers charge for this service.
Reclothe
Replace the worn or damaged clothing (wire) on rollers of a carding machine with new clothing. Recombing
Combing of top slivers after top dyeing. Recore test
Measurements made in accordance with the same IWTO Specification as that used for the original test, on a further core sample of raw wool. This sample is drawn from a lot for which the test result is in doubt. Such sample material must be obtained by re-sampling bales in accordance with current sampling standards or regulations. The recore test result must be adjusted for any declared or observed change in the net greasy mass of the wool.
Recovered wool
Wool recovered from rags and used in cheaper woollen goods. There are two types: (1) Shoddy is the product from knitted and loosely woven products; (2) mungo is the product of tightly woven products.
Rectilinear comb (or Continental comb, French comb)
The arrangement of the pins on this comb are in straight lines rather than in a circular arrangement, as for the now-obsolete Noble comb. Also called the Heilmann comb after its inventor. (See Combing, Noble comb, Appendix 12)
Recycled pack
HDPE (high density polyethylene) wool pack which has been repaired in accordance with the Code of Practice for Recycled Packs.
Red Book
This publication contains full specifications of the current IWTO Test Methods. (See IWTO)
Red eye A wether.

Reed Series of closely-spaced, parallel wires in a frame that is used for (1) spacing the warp threads in a loom, (2) guiding the shuttle or rapier during weft insertion, (3) beating up the weft against the fell. The space between two adjacent wire is called a dent; a warp yarn is drawn through this space. (See Weaving, Appendix 16)
Reel
See Winch Regain (or Moisture regain, Moisture content)
Amount of moisture in wool fibres, expressed as a percentage of the clean oven dry weight. Standard regain is brought about when wool comes to equilibrium with air at 20°C and 65% relative humidity. Most wool is traded on the basis of its mass at regains specified by IWTO Regulations. Processed wool is adjusted to a particular regain according to national and international agreements (eg. 18.25% for dry combed tops and 16 or 17% regain for scoured wool).
Registered laboratory
See Accreditation Registered Sampler and Weigher
Employee of an accredited representative who has been trained in the weighing, sampling and repacking of wools to the satisfaction of the test house and whose signature is entered on each sampling report.
Regurgitation
The movement of undigested fibrous feed from the sheep’s rumen to the mouth for further chewing. Reissued certificate
Wool test certificate which is reissued to take into account one or more of the following factors:
- correction of documentary or testing errors.
- rebrand or change in identifying marks.
- recalculation after drawing of sample which may not exceed 1% of total weight of the tested lot.
- revised detail of sale offering or reoffering.
- repacking under test house supervision.
- replacement of lost or damaged certificate after proof of entitlement. Reject bales
A lot remove from the sale because bales are unevenly classed or subject to untrue representation. Relative humidity
Amount of water vapour in the air, expressed as a percentage of the maximum amount that the air could hold at the given temperature. It is an important factor in processing wool because wool absorbs and releases atmospheric moisture constantly. (See Regain)
Relaxation shrinkage
Shrinkage of a fabric occurring when the stretching caused by stresses imposed on the fibres and yarns during processing disappear. It occurs under moist conditions when the fabric is not restrained.
Re-offered lot
Previously ‘passed in' lot, which is put up for sale again in a subsequent auction catalogue. Repeatibility
Statistical measure of the consistency between measurements or appraisals of the same sample. Replacements
Sheep acquired to make up the number in a flock to the required level. Replacement rate
Rate at which ewes are replaced in a flock. Repellancy
Ability of a fabric to resist wetting and staining. Reprocessed wool
Wool that has been spun, woven, knitted, or felted into a wool fabric but has not been utilised by consumers (eg. tailors cutting). It is then reprocessed into a fibrous state for subsequent reprocessing. Sometimes called reworked or reclaimed wool. (See New wool, Virgin wool)

Reproduction A group of ewes is generally mated by a single ram, either chosen by the breeder, or has established dominance with other rams in feral populations. Most sheep are seasonal breeders, although some can breed all year round. Ewes generally reach sexual maturity at 6 – 8 months of age and rams generally at 4 – 6 months. Ewes have oestrus cycles about every 17 days during which they emit a scent and indicate readiness to rams. After mating sheep have a gestation period of about 5 months and normal labour may take 1-3 hours. Although some breeds produce large litters of lambs, most produce single or twin lambs.
Reproduction data for sheep
Season of breeding: Commonly autumn (February to May in New Zealand), however this is breed-dependent. Merino and Dorset sheep can breed in the spring. In Australia more ewes are joined in the spring than the autumn on account of feed availability.
Ewe:
Length of oestrus (heat): 24 hours (range 4 – 72 hours)
Length of oestrus cycle (interval between successive heats): 17 days (range 14-21 days)
Time of ovulation: 24-30 hours from beginning of oestrus
Pregnancy: 140-150 days
Puberty age: 7-8 months, depending on live weight.
Ram:
Serviceability: In Australia extensive grazing conditions require 1 ram to 30-35 ewes (60 day breeding season). In New Zealand it is common to use 1 ram per 100 ewes and sometimes up to 1 ram per 150 ewes under intensive farming conditions.
Ejaculate volume: 0.8 – 1.2 ml
Sperm concentration: 2,000-3,000 million per ml Reserve
Instruction from the wool grower to the broker notifying them of the minimum price that will be accepted at the auction. The lot will be passed in if the reserve price is not reached.
Residual grease
Percentage of solvent soluble residues present in the scoured dried wool. Established by separating out in the Soxhlet apparatus, using ethanol or dichloromethane (DCM) as solvents. (See Alcohol Extractables)
Residues
Leftover chemical remaining on an animal after a remedy has been administered. Chemical residues on wool are important as a potential health hazard to humans (eg, in wool handling) or as an environmental contaminant (eg, wool scour effluent).
Resilience
Ability of a fibre mass, yarn or fabric to spring back to its original form after compression. For a carpet, it is the ability of the pile to recover its original appearance and thickness after being subjected to compressive forces or crushing under traffic.
Resistance
The ability to withstand the action of remedy which is (or was previously) effective against a significant proportion of the population. This can refer to bacteria (eg, antiobiotic resistance) or parasites (eg, anthelmintic or lousicide resistance). Resistance develops over time that the bacteria or parasite has been exposed to repeated treatments of the remedy.
Resistance to compression (RC)
Force (or pressure) required to compress a standard mass of scoured and carded wool into a fixed volume. This is related to the mean fibre diameter, handle and bulk of the wool and is also positively related to the amount of fibre crimp; (ie. highly crimped wool has greater resistance to compression than low crimp wool of the same diameter). The test result is expressed in kilopascals (kPa). This test, which uses higher pressures than the bulk test, is more appropriate for fine wools destined for worsted weaving yarns than for coarser wools processed on the woollen system. (See Bulk)
Resist dyeing (Resist printing)
Process of dyeing selected areas of yarns or fabrics by covering up the areas intended to remain undyed, so they ‘resist’ the dye. The process may be repeated several times to create a variety of colours on a single cloth. Resist is the substance applied to prevent the uptake or fixation of the dye.
Retest
Set of measurements made, in accordance with the relevant IWTO Test Methods, on a further sample of raw wool drawn from a consignment for which the original Certificate is in doubt. Such sample material must be obtained by recoring and reweighing all bales, in accordance with the IWTO Core Test Regulations. This differs from the recore check test in that duplicate core sample (or duplicate samples and duplicate sets of staples) are drawn for possible testing by two separate test houses to resolve a disputed result. The sample materials must be obtained by re-coring and hand sampling where applicable and re-weighing all bales.

Re-used wool Similar to reprocessed wool except that the wool products have been used by consumers (rags). (See Mungo, Shoddy)
Ribby pelts
Pelts from wrinkled sheep, such as Merino's, which are of limited usefulness for making leather. Rib knit
Basic stitch in which the knitting machines require two sets of needles operating at right angles to each other. Rib knits have a very high degree of elasticity in the crosswise direction. This knitted fabric is used for complete garments and for such specialized uses as sleeve bands, neck bands, sweater waistbands, and special types of trims for use with other knit or woven fabrics. Lightweight sweaters in rib knits provide a close, body-hugging fit.
Rib weave
One of the plain weave variations, which is formed by using: 1) heavy yarns in the warp or filling direction, or 2) a substantially higher number of yarns per inch in one direction than in the other, or 3) several yarns grouped together as one. Rib fabrics are all characterized by having a slight ridge effect in one direction, usually the filling. Such fabrics may have problems with yarn slippage, abrasion resistance, and tear strength. Examples of this construction include broadcloth, poplin, taffeta, faille, shantung, and cord fabric.
Rig
Male sheep with one testicle not removed but remaining in the abdominal cavity. Riggwelter
Old English term (from Norse) for a sheep that has fallen onto its back and is unable to get up. (see Cast sheep) Ring
Mob of sheep moving in a circle. Ringer
Fastest shearer in the gang, ie, with the highest tally for a day’s shearing. Occupies the number one position on the board until he (or she) is successfully challenged. The ringer is said to ‘ring the shed’ by shearing the highest tally, ie, by ‘running rings’ around the other shearers. Traditionally, a rival shearer must shear a larger tally for three consecutive days before he (or she) can take the ringer’s stand.
Ringing
Removal of a circle of wool from around the pizzle of a male sheep. Ringing sheep
A fault in a dog where it goes in a complete circle around the sheep and comes back to its handler. It fails to stop after its out-run, halfway around the sheep, and directly opposite the handler.
Ring spinning
Spinning system in which twist is inserted in a yarn using a traveller revolving at high speed around a ring. This is the most common method of producing wool yarns, by the woollen, worsted and semiworsted routes. (See Appendix 13)
Rise
A north of England term for the growth of new wool between the skin and last year’s fleece. Roach back
A hump or arch in the backline of a sheep, usually in the loin area. Rolag
Short length of carded wool. A loose roll of wool fibres that has been hand carded. Roller drafting
Process of drawing out a roving or sliver to reduce its linear density (thickness). It uses two pairs of counter-rotating rollers, with different surface speeds. The ratio of the surface speed of the front (exit) rollers to the surface speed of the back (entry) rollers is called the draft ratio. (See Draft, Drawing)
Roller lapping (or Rollerlap)
Top made out of very strong, lustrous wool about 200 mm or more in length and used to cover the rollers of the squeeze-heads in a scour. This term is also used for the wool suitable for this purpose.
Roller printing
The design is applied to the fabric using etched or engraved rollers. Rolling
Rolling a fleece into a compact bundle (with the fleece side outermost) that will hold together when packed into a bale. The shoulder roll is one method of rolling which presents the shoulder wool rather than the back wool as the bulk of the wool presented and giving a better appearance and fairer example of what the fleece contains.

Romaine Amount of noil produced during wool combing, expressed as a percentage of the total top and noil produced. Another term for this is noilage. (See Tear)
Roman nose
A distinctive convex shape to the bridge of a sheep’s nose, such as in the Border Leicester breed. Romcross
Collective term for New Zealand crossbred wool, which is mainly based on the Romney breed. (See Romney) Romney
More correctly called the New Zealand Romney. The most numerous sheep breed in New Zealand, originating from the Romney Marsh sheep from England. A dual purpose breed producing long, medium-lustre wool, staple length 125-175mm. mean fibre diameter 33-39 microns. (See Appendix 1)
Rooing
Process of removing the fleece from a sheep by hand plucking the wool. Many primitive sheep breeds retain the tendency to shed the current year’s fleece growth in late spring or early summer. At this point the fibre diameter become thinner and the fleece begins to loosen naturally (especially in certain breeds), so no distress is caused to the sheep when rooing is carried out.
Rope marks (Running marks)
Long crease marks in dyed or finished fabrics, running lengthwise. They are caused by wet processing a fabric in rope form.
Ropey wool (or Roped wool)
Wool which has become tangled, knotted and felted during scouring. Rosella
A sheep that has lost part of its fleece before shearing and so is easy to shear. Rotary gill
Type of gillbox where the faller bars have been replaced with shafts which have discs with protruding points. These can be set with different spacings between the discs, through which the sliver is drawn. (See Gilling)
Rotary pressing
Pressing a fabric between a large roller and a metal shoe; either or both may be heated. Rotary screen
A seamless cylindrical screen constructed from a metal mesh, used for rotary printing of fabrics. Rotational crossbreeding
Systematic crossing of two or more breeds in which the crossbred ewes are mated to rams of the breed contributing the least genes to that ewe’s phenotype.
Rotational grazing
Where a flock of sheep is moved to a new grazing area on a daily or weekly basis (See Set stocking). Rough ‘em
Rough, careless shearing. Opposite to pink ‘em. Rousabout (or Rouseabout, Rousie)
General shed hand in a shearing gang whose job is to keep the sheep up to the catching pens, change the fadges, assist the presser, etc. In Australia this term usually refers to an adult shed hand, while the terms lounge-about and blue tongue are reserved for younger shed hands.
Roving
Relatively fine, even, strand of fibres with zero or low twist, drafted from a sliver. It is the input material for worsted spinning. This term is also used for the production of roving from sliver.
Rubfastness
Ability of a dyed fabric to retain its colour and not to transfer any dye to be transferred to another fabric with which it has frictional contact (see Crocking, Crockmeter).
Rug
Soft floor covering, not fastened to the floor. As a general rule, a rug does not cover the entire floor. Rumen
First, and largest, compartment in the ruminant stomach. Also called the paunch.
THE EWENIQUE GLOSSARY OF SHEEP & WOOL TERMS
© AgResearch 2012 115
Ruminant Animal with a four-part stomach (rumen, reticulum, omasum and abomasum) which is capable of digesting cellulose. The largest part is the rumen from which grass is regurgitated for further chewing (chewing the cud). Cattle sheep, goats and deer are ruminants while pigs and poultry are simple-stomached (monogastric) animals.
Run
Farming – alternative term for a sheep station. (See Station)
Shearing - actual working time between breaks in the shearing shed, typically two hours. Today a typical day’s shearing is divided into four two-hour runs. Traditionally, shearers completed a run before breakfast, two stretches in the morning and three in the afternoon, divided by meal times and smokos.
Run-holder
Station owner. The name originates from the issuing of a licence to ‘run’ sheep on an area of land. These blocks of land date from early settlement when new country was divided into ‘runs’ by the government. A ‘licence to occupy’ permits the run-holder to farm the property under a leasehold arrangement, with the government still owning the land. (See Squatter)
Run-off
Area of land, possibly separated from the main area, where young or dry (non-lactating) sheep are run. Run-out fleece
Fleece showing a variation in crimp formation between the butt and tip of the staple.
Ryegrass staggers A brain disease of sheep and other farm animals, caused by the ingestion of a toxin called lolitrem B, produced by a fungus in perennial rygrass. The toxin has a damaging effect on cells in the brain that coordinate movement.
Corriedale
A medium size sheep with white face and legs and a black nose. There is usually some wool on the face and it has a well-covered
poll.
Staple: Less blocky (rectangular) than a Merino but less tippy than most crossbred wool. The fleece is medium to fine, with a
pronounced crimp and a medium crimp spacing.
Body weight 45 – 70 kg (ewes)
Fleece weight 4.5 – 6.5 kg
Staple length 75 – 125 mm (annual growth)
Fibre diameter range 28 – 33 microns (adult sheep)
Lamb production 90 – 130 %
A dual purpose sheep, with equal emphasis on meat and wool production. Developed in in 1868 by mating English long wool
breeds with Merino, and interbreeding the progency to produce New Zealand’s first indigenous breed. The Corriedale is an
adaptable sheep, farmed on drier land, mainly hilly country on the east coast of the South Island. New Zealand Corriedales have
provided the foundation of flocks in Australia, Uruguay, Argentina, Chile and China.
Corriedale wool is used for medium weight outer garments, worsteds, light tweeds, hand knitting yarns and upholstery fabrics.

S Safety clutch
Adjustable, spring-loaded clutch in the short gut of a shearing machine. It is designed to slip should the handpiece become jammed.
Sale by Description
Method of offering of wool for sale, by the cataloguing of previously appraised and measured grab samples but which are not readily available for inspection.
Sale by Private Treaty
Any sale of wool conducted privately (ie. outside the auction). Sale by Sample
Method of displaying wool before an auction, where only a full staple length sample withdrawn mechanically from the line of wool is displayed in a cardboard box for buyer evaluation along with catalogued test results for yield, vegetable matter, fibre diameter, etc. The original concept was proposed by Dr Ian Fraser of WRONZ in 1967, leading to its subsequent adoption by the wool industry, first in Australia and then in New Zealand.
Sale by Separation
Selling of wool in a centre other than that in which the wool is stored. Sale by Tender
Wools offered outside the auction system with the buyers submitting prices. Sale catalogue (or Auction catalogue)
Booklet provided by each wool broker during the week of an auction to inform buyers of grower’s lots available to purchase. The information for each lot on offer contains both their test results and lot details (number of bales, weight, brand, description, etc.). (See Auction)
Sale lot
Group of bales of similar mass and usually the same farm, containing greasy wool prepared for sale according to accepted trade practices. Usually more than 3 bales.
Sale roster
Schedule of wool auction sales published for each new wool-selling season. It states the venues, dates and projected quantities to be offered for sale.
Salt marsh lamb
The meat of sheep which graze on salt marsh in coastal estuaries washed by tides and which support salt-tolerant grasses and herbs.
Sample
Refers to wool taken from and representative of the lot, scourment or delivery by the methods of grab, hand and core sampling. In order to issue IWTO test certificates, the sample must be drawn in accordance with the relevant IWTO Test Regulations.
Sample container
Container for wool constructed so that there is no loss of material or undue exposure to the atmosphere, and thus the moisture content will not change during storage before weighing.
Sandy back
Back wool containing sand, grit or dirt. Sateen
A woven fabric with long weft floats on its surface. Satin
A woven fabric with long warp floats on its surface.
Saxon Strain of fine and superfine wool Merino, originating from Saxony in Germany. (See Escorial)
Saxony
Cut pile carpet with a reasonably thick pile, made of moderately twisted yarn so that the individual tufts are upright and visible. The dominant style in the USA domestic carpet market.
Also a older term used for goods made from Merino wool on the woollen system. Scabby mouth
Common name for the contagious disease pustular dermatitis or contagious ecthyma. It is a viral disease of sheep, attaching damaged skin areas around the mouth and causing sores. Also called Orf.

Scales
- The cuticle (outer layer) of the wool fibre is constructed of overlapping scale cells which point towards the fibre tip (see Cuticle).
- A bale weighing device, which is certified annually in New Zealand by the Trade Measurement Unit of the Ministry of Consumer Affairs.
Schedule
Price offered by meat exporting companies for various weights and grades of meat. Schlumberger comb
Rectilinear comb designed originally for cotton, later adapted for the dry combing of short wools (about 35 mm in length).
Schlumberger Dry Combing Yield (SD)
One of the several commercial yields, calculated from the Wool Base, and accepted generally as the expected yield after scouring and processing through a typical comb without adding oil. SD yield is the result most often used to make greasy and clean conversions (prices and weights) in New Zealand. (See Yield)
Scottish Blackface
Coarse, highly medullated wool produced in the United Kingdom. It is included as a component in certain carpet yarn blends to provide resilience to the carpet pile. The presence of some pigmented fibres may restrict the use of this wool for light coloured yarns. A Scottish Blackface sheep is called a ‘blackie’ in Northumbria.
Scour
Wool scouring plant (see Scouring (process), Appendix 8). Scourable diffuse yellow
Fleece discolouration in a fleece of a butter colour, which is readily removed by scouring. Scoured wool
Greasy or slipe wools that have been commercially scoured, carbonised or solvent degreased, excluding washed or partly washed wools.
Scouring (process)
High production washing of wool to remove the natural impurities of wax, suint, and dirt, followed by drying and baling. The term may also refer to the removal of contaminants from yarns and fabrics by washing in warm water and detergent (see Appendix 8).
Scouring (sheep)
Severe diarrhoea in sheep Scouring line (or Scouring train)
Integrated chain of machinery for opening, blending, scouring, rinsing and drying in a scouring plant (Appendix 8) Scourment (or Scouring lot)
Processing consignment for wool scouring, usually consisting of a blend of numerous farm lots. It is destined for a yarn manufacturer or topmaker.
Scours
Diarrhea in sheep. Causes can include overfeeding, viral bacteria and protozoan infections. Scrag
Back of a sheep’s neck. Scrapie
Fatal disease of the central nervous system of sheep and goats. It is slow, progressive and difficult to control. Scray
A curved trough in which fabric accumulates, either during a dwell period in a process or while awaiting treatment. Screen
Australian term for the skirting table. Scribbler
First half of a woollen carding machine between the feed hopper and the intermediate feed. (See Carding (Woollen), Peralta roller, Intermediate feed, Appendix 11).
The scribbler was once a person working in a clothiers factory who oiled the wool to make it easier to work with. From around 1675 the scribbler used hand cards to pull the wool over a scribbling horse, a frame covered with iron teeth set in leather leaves. Scribblers were often older or disabled workers. The fibres could then be hand carded. From the 1790s scribbling engines took over this work. They were originally horse-powered but later were powered by water, then steam.

Screen printing Method of printing comparable to using a stencil. The background design is painted on the screen with printing paste and the dye is printed through the exposed fabric. Different colours require different screens.
Scrub
Sheep whose ancestry is so mixed it does not resemble any particular breed or cross. Scud
Cellular debris from the skin in dead wool. Sculptured pile
Carpet pile formed from high and low pile areas, such as high-low loop and cut and loop. Scurs
Little horns that have broken the skin of a sheep, but have not grown. Scutching
Converting a fabric from rope form to open width form. Sealed container
For grab samples of wool, a container that is closed in a manner which prevents unauthorized interference with the contents. For core samples, a container that is impermeable to moisture so that the contents are kept without change to the moisture content.
Seam strength/slippage
Ability of a fabric to withstand forces trying to pull apart a seam that has been stitched into it, and thus open up holes in the fabric. A tensile test is used to assess this.
Season (for wool selling)
Runs from July 1 to June 30 each year in New Zealand and Australia. Sebaceous glands (or Wax glands)
Glands attached to primary and secondary wool follicles and which secrete wool wax. Merino sheep, which have a higher ratio of secondary follicles, produce greater quantities of wax than coarser-woolled sheep (see Follicle, Suderiferous gland, Appendix 4).
Second cuts
Short staples resulting from shearing an area on a sheep which has already been shorn. The result from a shearer not taking the wool off close enough to the sheep’s skin and having to make a second cut to remove the rest of the wool. A second cut differs from a normal staple in that both ends are severed and no tip end is evident. In staple length measurement, second cuts are considered as staples. Also called ‘two-cut’ and ‘chaff’. Second cuts have little value because of their shortness.
Secondary follicle
Wool follicle without an associated suderiferous (sweat) gland or small arrector pili muscle. For finer wools the ratio of primary to secondary fibre diameters tends to decrease while the ratio of the number of secondary to primary fibres increases (see Primary follicle, Appendix 4)
Secondary backing
In tufted wool carpet, an additional backing is bonded to the primary backing with latex to improve dimensional stability.
Seconds
Textile products which, because of a fault or imperfection, to not meet an agreed standard of quality. Second shear wool
Wool from sheep shorn more frequently than once every 8 months. Sometimes called second clip (See Prem shorn),
Sectional warping
Preparation of a warp beam involving (1) winding a warp in sections on a reel and (2) transferring (‘beaming-off’) the complete warp from the reel onto a warp beam.
Security of a sample
Measures taken to ensure that the integrity of a sample and its certificates or documentation are preserved. Seed
Ovules from plants (other than burr producers) which adhere to the wool to cause vegetable contamination (ie. bidi-bidi, grass seeds, etc.).
Seedy wool (or Seed)
Wools contaminated with seed (usually from grasses), which are more difficult to remove than burrs. There are many small, hard types of seed which generally cause few problems in processing, with the exception of carrot seed.

Selection Practice of deciding which individuals will be allowed to mate to produce the next generation.
Selection criteria Specific traits measured and used as the basis for choosing replacement ewes and rams.
Selection difference (or Selection differential)
Difference between the average for a trait in replacement animals and the average of the group from which replacements were chosen. The expected response from selection equals selection differential times the heritability of a trait.
Selection goals
Long-term direction of a flock that should provide a clear picture of the desired direction of genetic change in a flock, based on the economic realities of the production system
Selection index Selection method that ranks individual animals for economic merit, based on two or more traits.
Selection intensity The smaller the proportion of the lamb crop that needs to be saved for replacements, the greater the selection intensity (Iand hence the larger the selection differential.
Self-feeder
Feeders for sheep and cattle where they can access feed when they wish. Self-replacing flock
The main production system used in the Merino industry, involving the selection of superior young replacement ewes from the previous year’s flock and returning them to the main ewe flock. The oldest ewes (cast for age) are culled.
Self-twist spinning
On the Repco self-twist spinning machine S and Z twist is inserted alternately in a pair of strands which are then brought together, out of phase along their length to wrap around each other. A stable two-ply yarn with alternating twist is thus formed. This method has a number of advantages over conventional worsted ring spinning – production rate, cleanliness, spinning limits (35 fibres per strand) and noise – but is mostly used for spinning high bulk acrylic fibre for knitting.
Selling centre
Towns where wool is sold by public auction, generally at weekly intervals in the wool-selling season. Currently Napier in the North Island and Christchurch in the South Island are the selling centres for New Zealand wool. (See Auction)
Selvedge
The bound edge of a woven fabric, running parallel to the warp and which prevents the fabric from fraying. Semen
Ejaculate of a ram that contains fluids from the accessory glands and spermatozoa. Semi-worsted yarn
Strong spun thread in which fibres have been partially aligned by gilling before spinning. The yarns are more even, compact and smoother than woollen spun yarns, but cannot be quite as fine or as smooth as worsted yarns. They tend to have lower bulk (ie, leaner) than woollen spun yarns of similar count and twist. (see Appendix 7).
Semi-worsted processing
High production spinning route developed to produce yams with similar characteristics to worsted spun yarn, but in a shorter, more economic way. In most countries this route is used with synthetic staple fibre, but in New Zealand wool is processed for carpet yarn. Because there is no combing step, the wool used in this route must be of good uniform length, have good tensile strength and be free from vegetable matter. In carpet yarn manufacture a low level of carding lubricant is used so subsequent yarn scouring is not required. (See Appendix 7)
Serge
Type of twill fabric that in the worsted variety is used for making military uniforms, suits and coats. The term is also used for high quality wollen woven cloth. Originally made of wool, but now made of other fibres or blends of wool with other fibres.
Serrations
Tips of the cuticle scales which project from the body of the wool fibre and assist felting. Fine wool generally has more serrations than coarse wool. (See Cuticle, Felting)
Serve
To mate a ram with a ewe.

Setting (card clothing)
Systematic placement of the wire staples in flexible card clothing (or fillet). The rib setting is the most commonly used on woollen cards.
Setting (yarn process)
Process of consolidating the twist into a wool yarn destined for cut-pile carpets requiring good tuft definition and good texture retention in use. Steam, hot water or a solution of sodium metabisulphite may be used to achieve this, usually in a dye vessel, tape scour or a Chemset (or Twistset) machine.

Shaking
Method of removing loose items such as twigs, dung and some vegetable matter from wool. It is less costly and damaging to remove contaminants using gravity rather than by violent action to the fibres.
Shandygaff
An old term for various sorts of sheep mixed together in a yard. To shandygaff is to put wet sheep with dry sheep in the wool shed to deceive the shearers.
Shanks (or Shankings)
Wool covering the lower parts of a sheep’s legs below the knees and hocks, comprising short, inferior and kempy fibres. (See Appendix 19)
Shaping

Group of people contracted by a farmer to shear, handle and bale the wool clip. Shearing shed (or Woolshed, Shed)
Building on a farm in which sheep are shorn and the preparation of the wool for sale is carried out. Synonymous with wool shed and often shortened to shed.
Shearling
Recently shorn sheep having wool of a short length (ie, <2.5cm). Mostly used for a young sheep after its first or second shearing.
Shears
- second shear fleeces - another name for hand blades (see Blades)
Shed
- Abbreviation for the shearing shed. - In sheep handling, to separate one or more animals from a group. - In weaving, the shed is the opening between warp threads on a loom and through which the shuttle passes. It is
formed by raising some warp threads by means of their harnesses while others are left down. Sometimes called the shed space (See Appendix 16).
Shed fibre
- Fibres released from the follicle (ie. kemp fibres, first generation (halo hair)) fibres from of the lamb fleece. - Stress released fibres from mature sheep (a prerequisite to cotting). - Fibres accumulating on the surface of a recently laid cut-pile wool carpet. (See Shedding)

Synonymous with wool handler. Staff employed to handle and usually prepare the shorn wool in the farm shearing shed. In Australia, the term steel beak is also used. (See Rouseabout).
Shedding
- Weaving: Formation of a shed, ie, the opening between the warp threads across the loom, in the weaving cycle. The weft yarn is inserted through this opening using a shuttle, rapier, projectile, air jet or water jet. (See Appendix 16)
- Carpet performance: Loss of pile fibres by the action of foot traffic early in the life of a carpet. This is mostly short fibres in cut pile carpets because these are less well retained by the tufts than longer fibres.
Shedding breeds
Sheep meat breeds that shed fleeces containing pigmented and medullated fibres. Examples include Wiltshire Horn, Wiltipoll, Damara and Dorper. Their wool must be kept separated from other lines to prevent contamination of these lines.
Shed-up
Shutting woolly sheep in a shearing shed (or under cover outside the shed) before shearing to prevent them from getting wet from rain or dew.
Sheep
Quadraped ruminant mammal of the genus Ovis, of the family Bovidae. They are in the same subfamily (Caprinae) as goats and are bred across a wide range of domestic varieties (breeds). The life span is approximately 12 years, which largely depends on the state of their teeth. The gestation period for sheep is 5 months. An old name for a sheep is ‘woolbird’.

Sheep run
Extensive area of land used for grazing sheep. Sheepsback insurance
Insurance cover over wool from shearing to its arrival at the wool broker's stores. For auction sales only. Sheep senses
Sheep have good hearing and are sensitive to noise when being handled.
They have horizontal, slit-shaped pupils and have excellent peripheral vision. Their visual field is in the range 270 o – 320o so sheep can see behind themselves without turning their heads.
They have poor depth perception so that shadows or dips in the ground may cause sheep to balk. In general sheep tend to move out of the dark and into well-lit areas.
Sheep have excellent sense of smell and have scent glands just in front of their eyes and interdigitally on their feet. The purpose of these glands is uncertain, but they may be used in breeding behaviours.
Sheep-sick
Describes land that has been degraded as a result of over-grazing by sheep. Sheepskin
Garment or rug from sheep’s skin, with the wool on, or leather from sheep’s skin. Double-faced sheepskin is where a tannery produces a quality tanned product on both the wool side and the skin side of the sheepskin (or lambskin). Single-faced sheepskin is where the tannery producesa useable tanned product on the wool side only. The skin side may be marked and the dyeing may be uneven.
Sheepwalk
Area of rough grazing occupied by a flock, or forming part of a farm. Sheep yards
Set of pens for the purpose of handling sheep. Consist of several yards with a diamond, crush pens and a drafting race.
Shelter

Shipping mark
Shipping consignment may be identified by the use, singularly, or in combination, of a symbol, numbers or letters, applied to each individual bale. It may also be associated with the consecutive renumbering of all bales in the consignment but renumbering alone does not constitute a shipping mark.
Shirley Analyser
Laboratory carding machine used for removing vegetable matter from a scoured wool sample and blending the fibres for subsequent measurement of fibre diameter and colour.
Shirley Wheel
Device for removing wool from a flow of air. A perforated screen intercepts the air duct that is transporting the wool and allows the air to pass through while the wool falls away. Widely used in wool scours.
Shive
Vegetable matter, usually that contained in the back wool, such as manuka leaf, macrocarpa leaf, barley grass etc., hence the term 'shivey backs'. It does not include burrs or seed. Shive is difficult to remove during processing because it tends to be long and thin, similar to a wool fibre. Sometimes called shiv or chive.
Shivy (or Shivey)
Wool containing shive. Shoddy
Wool recovered from knitted goods and loosely woven cloths made from soft spun yarns. A superior type of recovered wool. Benjamin Law first produced shoddy and mungo in 1813 and this became the basis of the UK shoddy industries in the Batley, Morley, Dewsbury and Ossett. In 1860 the town of Batley had 80 firms producing 7000 tons of shoddy per year.
Shornie
Australian term for a freshly shorn sheep. Shortwool sheep (or Down sheep)
Sheep producing wool with short staple length (5-9 cm), finer fibres (25-34 microns) than longwools. The wool has low lustre, high fibre crimp and bulk. The breeds include Shropshire, Hampshire, Suffolk, Ryeland, South Suffolk, Southdown, Poll Dorset, Dorset Down and Dorset Horn. (See Down wool)

Expresses the percentage of fibres less than a specified length, eg, 20 or 40 mm. It is usually measured using the Almeter. (See Almeter)
Shrek
A Merino wether from Bendigo Station in Central Otago, New Zealand who gained international fame in 2004 after he avoided being caught and shorn for six years, presumably by hiding in a cave during musters. After eventually being caught, Shrek was shorn by a professional shearer in 20 minutes. His fleece weighed 27kg (about six times the average fleece weight for a Merino). Shrek was named after the popular book and film character. He died in 2011.
Shrinkage
- loss of carcass weight between slaughter and sale, mainly due to the loss of water from the meat. - loss in weight of a wool consignment due to scouring, expressed as percentage by weight of the greasy wool
entering the process. - reduction in the dimensions of woollen fabrics or garments during finishing due to the tendency of the
wool fibre to felt.
THE EWENIQUE GLOSSARY OF SHEEP & WOOL TERMS
© AgResearch 2012 124
Shrink proofing (or Shrink resist treatment) Wool treatment to eliminate the risk of felting in shrinkage of a garment in use and cleaning. The Kroy-Hercosett process, which is most commonly used to provide shrink resistance for wool fabrics, involves a chlorine treatment to erode the surface scales on the fibre, followed by a resin application to coat the fibre and hence mask the scales.
Shuttle
Free-flying part of a traditional loom that carries the weft thread between the warp threads through the shed. Usually made of wood. It carries a small bobbin of yarn called a pirn. It has been replaced more more rapid insertion mechanisms (eg, rapier, projectile and air jet) in modern looms. (See Loom, Weft insertion, Appendix 16).
Shy feeders
Animals, usually lambs, that persistently refuse to eat supplementary feed. Sibs (or Full sibs)
Brother and sisters from the same sire and dam (ie, ewe and ram). Silage
Sheep (and cattle) feed made from young grass high in protein, cut when it starts to show seed heads, then wilted and stored in airtight containers (silos, bunkers or plastic wrap). Baleage is made from more mature pasture and is wrapped in plastic wrap are wilting. It has lower feed value (energy and protein) than silage.
Singeing
Process where rapidly-moving fabric moves across a flame or very hot plate in order to remove fibres protruding from the fabric surface.
Singles yarn (or Single yarn)
Yam composed of one twisted strand of fibres. Singleton

Sirolan Fleecescan
Set of transportable instruments, based on Laserscan technology, for rapidly measuring the fibre diameter of fleeces as they are shorn in the shearing shed. It is capable of testing 100 fleeces per hour, with each result available within one minute.
Sirolan Laserscan
Sophisticated, computer-controlled instrument used to measure mean fibre diameter, fibre diameter distribution, fibre curvature and comfort factor of wool. It operates by detecting shadows in a laser beam, caused by fibre snippets that are carried through the beam by the flow of a suitable liquid. Often just referred to Laserscan. (See Fibre diameter, Fibre diameter distribution, Curvature, Comfort factor)
Siroscour
Scouring system developed by CSIRO in Australia especially for fine wools, and to handle different patterns of contaminant removal. The preferred mode of operation is three-stage scouring in which the functions of the bowls are divided into three stages.
Sirospun
Modification to a worsted ring spinning frame that enables two rovings to be drafted in parallel, then twisted together. It therefore eliminates the need for a twisting step in yarn manufacture (See Twisting, Solospun).
Sisal
Dense loop pile wool carpet with a similar look to traditional mats made from plant fibres. They have well-defined parallel lines of loops which may be of uniform height or have a combination of high and low lines.
Six tooth

‘Sixty-nine’ Call made to let shearers and shedhands know that ladies and visitors are entering the shearing shed, so that they will be on their best behaviour for the visitors and stop telling ‘stories”. ‘Ninety-nine’ was also used. (See ‘Ducks on the Pond’)
Sizing (or Slashing)
Application of a gelatinous compound, polyvinyl alcohol or starch (size) to warp yarns before weaving. Sizing, which is carried out on a slasher, protects the yarn from the abrasive action of the loom. It provides stiffness and temporarily binds the fibres. (See Desizing)
Skein
Unsupported coil of yarn where the two ends are tied to maintain the shape of the coil. Another name for hank. Skep
Pronounced ‘skip’. A trolley for carrying loose wool in a woolstore or mill. Skillion
An old Australian and New Zealand term for the sheep-holding part of a woolshed. Skin pieces
Clumps of wool attached to pieces of skin removed inadvertently during shearing and which, if not removed prior to manufacture, will cause problems in processing.
Skin wool
Wool from a fellmongery. In England this is wool obtained by non-lime processes (excludes slipe wool). Skip
Cage or box on wheels, used in broker’s store for weighing binned or classed wool. Skirtings (or Pieces)
Portions of the external edges of a fleece removed by the classer after shearing. Skirtings primarily form the piece lines of a clip, and are further categorized according to length and cleanliness. (See Appendix 5)
Skirting table
Large, rectangular, slatted table on which fleeces are thrown (ie, spread out) for skirting. The slats allow locks and second cuts to fall away.
Skirty
Fleeces that have been insufficiently skirted. Slink
Very young lamb. Slink skin is the skin and wool removed from a dead, new-born lamb. Slipe wool (or Slipes)
Wool removed from the skins (pelts) of slaughtered animals by a chemical depilatory which loosens the wool fibres. May be called fellmongered or pulled wool, or skin wool (although in some countries skin wool and slipe wool are different types). Body wool is graded as woolly lambs, shorn lambs and sheep while slipe oddments are graded as seconds, thirds and Slipemaster. (see Skin wool).
Slipemaster
Machine used to remove wool from pelt trimmings and head pieces in a fellmongery, and with the aid of scalding water.
Sliver
Thick, continuous strand of carded, gilled, (or carded, gilled and combed), wool fibres in a untwisted state. Sliver knitting
Machine knitting technique where light weight, single jersey fabric is formed from synthetic filaments and tufts of staple fibres such as wool are knitted at each loop to form a pile fabric on the reverse side. The resulting product is called a sliver knit or knit pile fabric. Modern, computer controlled machines, using coloured slivers, can create a wide range of attractive pile designs (see Pile knit).
Slub
Short, abnormally thick place in a yarn, usually with a diameter exceeding 2.5mm.This thickened place does not contain an entangled core of fibres as defined for a nep. Dyed slubs may be incorporated into a yarn to give a decorative effect (see Slub Yarn).
Slubbing (or Slubbings)
Continuous, weak, thin strand of fibres, the end result of the woollen carding process. The card web is divided into thin ribbons which are then rubbed by sets of aprons in the condenser to consolidate the fibres. This action gives the ribbons greater cohesion before spinning on the woollen spinning frame. (See Condenser, Appendix 11)
THE EWENIQUE GLOSSARY OF SHEEP & WOOL TERMS

See Intelligent Textiles. Smoko
Morning and afternoon tea break. Smooth mouth
Sheep that has lost all of its permanent incisor teeth, usually at around 7 years old or more. Smother
If the pens in the woolshed are filled too tightly, sheep may die through smothering during the night. Smothering of sheep can also occur if a dog forces a mob to take an abrupt turn while driving them.
Smut
A kemp fibre pigmentation found around the extremities of many breed of sheep, at any or all of the seven sites – lower muzzle, both horn sites, or the shanks of both fore and hind legs. The pigmentation ranges from ginger to chocolate, and grey to black. The term is restricted to fibre pigmentation and is not used for skin pigmentation.
S number (or Super S)
An S number on the label of wool apparel indicates the fineness of the fibre used. The higher the number the finer the wool. For example, 80s must have maximum fibre diameter of 19.75 micrometres or finer and 90s, 19.25 micrometres or finer. This scale continues to the 210s at 13.25 micrometre or finer. Thus each step of ten (as from 80s to 90s or 90s to 100s) corresponds to 0.5 micrometre less in allowed maximum fibre diameter. While S numbers are used for wool blend fabrics too, the term Super applies only to pure new wool products.
Snagger
Australian term for a old shearer who is past the retirement age but refuses to retire. Also used for a clumsy shearer.
Snarl
Length of yarn that has twisted on itself because of lively twist or insufficient tension. Snippets
Very short pieces of fibre, typically around 2 mm long, which are cut from a sample of wool or sliver using a mini-coring device or a guillotine. The snippets are used to measure fibre diameter and related wool properties. (See OFDA, Sirolan Laserscan, Projection Microscope)
Snob
Last sheep in the catching pen. This term is also used for a bad sheep to shear (which is often the last). Snow comb
Adaptor on a shearing hand piece to leave more wool on a sheep. (See Cover comb) Snowed in
When shearers are ahead of the wool table so that wool is lying around the floor waiting to go on the wool table. Shearers will be seen at their best when they get ahead of the rest of the shed. They enjoy snowing in, and usually will make the wool flow faster than ever. Also described as woolled-up.
Snow raking
Making a track for sheep to find their way through deep snow. Softening agent (or Softener)
Agent applied to a textile during wet finishing to give it a softer handle. Soft knops
Small balls of wool, which may have a shrink-resist treatment, produced by a mechanical process developed by WRONZ and used as fill materials in bedding products (ie, pillows, mattresses, duvets and futons).
Soft Rolling Skins
Soft Rolling Skins (SRS) system is a breeding system for merino sheep developed by Dr Jim Watts in Australia. Based on extensive research. SRS sheep are claimed to produce fleeces with unprecedented high levels of fibre density, length and quality. The resulting fineness, softness and uniformity are said to offer significant product opportunities.
THE EWENIQUE GLOSSARY OF SHEEP & WOOL TERMS
© AgResearch 2012 127
Soft waste By-product of carding, combing and drawing which is in a fibrous state without twist (so yarn waste, which is often called ‘hard’ waste, is excluded). When an end break occurs in woollen spinning, the build-up of slubbing fibre is immediately removed by a suction tube and accumulated in a cabinet at the end of the spinning frame. This type of soft waste, which is often called pneumafil, may be recycled back to the card hopper. (See Hard waste)
Solospun
Adaptation to a worsted ring spinning frame to enable a fine weavable singles yarn to be made. The fibres comprising the yarn are organized in such a way by the Solospun attachment that the yarn has an abrasion resistance in weaving that matches that of sized or two-fold weaving yarns. The device was developed jointly by WRONZ, CSIRO, and IWS (The Woolmark Company). (See Weavable singles yarn, Sirospun)
Solvent finishing
Washing knitwear in a organic solvent in a dry cleaning machine. Sonic Fineness Tester
Instrument developed by CSIRO to measure the mean fibre diameter of wool, but is no longer used in commercial testing. A vibrating speaker oscillates air through a compressed mass of wool fibres and the sound waves impinge on a sensor which measures the frequency of the waves. The output voltage generated by the sensor is related to the permeability (and hence the mean diameter) of the fibres.
Sore mouth
American term for a highly contagious viral infection that causes scabs around the nostrils and eyes and may affect the udders of lactating ewes.
Sorption
The process of taking up and holding moisture. Sorting
- Traditionally refers to splitting up bales of individual fleeces by mill hands into the different quality numbers. Little sorting is now carried out because of the labour cost.
- Separation of wool for colour, length, fineness and/or fault in a shearing shed, store or scour. Sound
Evenly grown wool, of good tensile strength throughout the staple. The opposite of tender wool. Sound mouth
Sheep whose teeth are firm and in their natural position; usually refers to an older sheep. Soundness
Tensile strength of wool fibres. Wools that break under gentle tension are termed unsound, weak or tender. They suffer excessive breakage in processing (See Staple strength)
South African Mutton Merino (or South African Meat Merino, SAMM)
A wool a meat sheep originating in South Africa but now found throughout the world. SAMM is derived from Deutsche Fleisch Merino animals imported from Europe in 1932 to improve meat and wool quality from sheep in South Africa. It has been developed as versatile, hardy, polled, dual-purpose breed. Ewes have good maternal instinct and high milk production. Ewes produce 3.5 – 4.5 kg of wool around 22-24 microns annually. They were first imported into Australia in 1996. In New Zealand, SAMM have been bred from embryos and semen imported from Australia, beginning in 1999.
South Australian Merino This strain was specifically bred to provide an economic return from wool in the arid pastoral conditions commonly found in that state. The largest of the Merino strains in Australia; generally longer, taller and heavier than the Peppin with less skni wrinkles than other strains. The wool tends to be towards the coarse end of the merino range.
Sox (or Socks)
Kempy, hairy fibre growing between the knee and hoof of a sheep. Sometimes the sox will be left on the sheep to avoid contamination of the shorn wool.
Soxhlet extraction apparatus
Equipment used by a test house for separating grease and similar wool contaminants from a sample of the fibre. These materials are extracted by repeatedly washing (percolation) of a test specimen with an organic solvent such as dichloromethane (DCM) or ethanol.
Space dyeing
Production of multicolour yarns by the application of different colours at intervals along a yarn by printing or other colouration methods (spraying, dipping etc.).
Specialty fibres
Wool-like fibres which are valued for their characteristics and limited supply. They include goat fibres (Angora, Cashmere, Cashgora, Mohair), camel hair and the camelid fibres (Llama, Alpaca, Vicuna, etc.)
THE EWENIQUE GLOSSARY OF SHEEP & WOOL TERMS
© AgResearch 2012 128
Specialty wools Wools possessing some value-adding characteristics such as bulk, medullation etc. (especially for carpets). (See Carpet wool)
Specification
Form supplied by a wool broker and completed by a wool grower and which accompanies each wool consignment. Specifies line descriptions, bale numbers, etc. This term is also used to define the wool requirements for specific types of yarn (in terms of fibre diameter, length, colour etc.)
Specking
Scouring: Picking out defects (eg, contamination) in scoured wool, usually done at the conveyor after the dryer. Fabric manufacture: the inspection of a fabric for tiny blemishes during finishing.
Spectrophotometer
Sophisticated instrument for measuring the colour of a material such as wool and textiles. It separates the light reflected from the sample into its component wavelengths. The measured variation in light energy, as a function of wavelength is converted into the tristimulus values (X, Y and Z) for ease of interpretation. (See Tristimulus values, Colour, Colour measurement)
Spectrum
A colouration technique using dye attract and dye resist resins to wool knitted garments and fabrics to enable quick response, multicoloured effects to be produced in subsequent piece dyeing.
Spindle
Vertical shaft on a ring spinning frame (or twister frame) which rotates at high speed and holds a tube onto which the twisted yarn is wound. A spinning frame typically has over one hundred spindles (see Appendix 13).
Spinnability
The ease of spinning a wool into yarn; mostly dependent its mean fibre diameter, length and crimp. Spinner
Manufacturer of yarn. Three types of yarn are used for wool processing (woollen, worsted and semiworsted), each with different fibre requirements, and manufacturers tend to specialize in one of these (see Appendix 7).
Spinner’s type
Fleece wools which, by virtue of their good colour, evenness for fibre diameter, length and soundness, and freedom from dust and vegetable matter need little additional sorting prior to manufacture and are bought directly by the spinner. Normally Merino, Halfbred and Corriedale fleece categories are used for the production of superior worsted yarn.
Spinning
Inserting twist into a continuous strand of fibres (eg, drafted roving, slubbing or sliver) to convert it into yarn (see Appendix 13)
Spinning count
Term of British origin used to describe the fineness of wool fibres. The count (such as 64s, 62s, etc.) refers to the number of hanks (560 yard lengths) of yarn that can be spun to a minimum thickness from one pound of top. Now largely replaced by the micron, the unit of mean fibre diameter (See Quality Number, Appendix 32).
Spinning fineness
Parameter calculated from the mean fibre diameter of a wool and its coefficient of variation of fibre diameter to provide a prediction of worsted spinning performance. It is measured in microns. The spinning fineness is equal to the mean fibre diameter when the coefficient of variation of diameter (CVD) equals 24%. For a wool with a CVD less than 24% the spinning fineness is less than the mean fibre diameter.
Spinning frame
Machine which converts a slubbing, sliver or roving into yarn by (1) inserting twist into the strands and (2) winding them onto bobbins. It consists of a series of many spindles arranged in a line and powered from a common drive shaft (see Appendix 13). (See Ring spinning)
Spinning limit
Minimum number of fibres required in the cross section of a yarn. Below this number the yarn will not spin well nor hold together adequately for knitting or weaving. This limit depends on the spinning route and is around 40 fibres for worsted spinning while at least 110 fibres in the cross-section are required for woollen spinning.
For example, using 20 µm wool, the minimum yarn counts that can be spun are 16 tex and 45 tex on the worsted and woollen systems respectively. For 35 micron wool the corresponding yarn counts are 50 tex and 139 tex respectively.
Spirality
A distortion of a circular-knitted fabric in which the wales follow a spiral path around the axis of the tube. It is caused by a yarn that is twist-lively (See Twist-lively)

S/P ratio Ratio of the number of secondary follicles to the number of primary follicles in a follicle group. This ratio varies markedly between breeds, for example around 18-25 for Merino sheep, 14 for Corriedale and 6 for Romney sheep. Generally, the higher the S/P ratio the finer the wool produced. (See Follicle group)
Splicing
Spinning - Joining of two ends of yarn, often using a jet of compressed air to entangle the fibres (air splicing). Knitting – the reinforcement of areas of knitted goods by the knitting of another yarn along with the main thread.
Sponging
The sequence of steaming, shrinking, pressing and reconditioning of finished (or partly finished) wool goods before garment manufacture. This completely relaxes the fabric and allows it to achieve dimensional stability before sewing. Also called steaming (See London Shrinkage).
Spook
To scare or frighten sheep, especially those not accustomed to being handled. Spool
See Beam, Appendix 13. SportwoolTM
Active sportswear fabric made from wool, with special moisture transport features. It is a composite fabric, combining an inner layer of machine-washable merino wool and outer layer of polyester.

Spun yarn
A yarn that consists of staple fibres such as wool, held together usually by twist. Squattocracy (or Squatocracy)
Families who first ‘owned’ farming properties in the early days of New Zealand. Governor George Grey’s lowering of the price of land in 1853 to encourage the landless to take up small holdings advantaged the speculators and large landholders instead. The rise of the ‘squattocracy’ and the locking up of much of the land by a small number of farmers was the result of Grey’s decision. This derogatory term is also used in Australia and other countries for wealthy landowners who are considered a powerful social class.
Squatter
Runholder or station owner. This term was once applied loosely to any large runholder. Squeegee
A rubber or metal blade which is used to force paste through the screen mesh in the screen printing of fabrics. Squeeze press
Pair of rollers, covered with roller lapping, that apply high pressure to a stream of wet wool to remove as much water as possible from the wool before it passes to the next stage of processing. In a wool scouring line a squeeze press is located between each bowl, and at the end of the last bowl just before the dryer.
Squeezer
Australian term for the wool press operator in a shearing shed. (See Tick Squasher) Stag
Male sheep that has been castrated after reaching maturity (ie, after approximately 6 months of age). A male sheep that has not been castrated properly as a lamb.
Stained wool Wool from the crutch of a sheep that is permanently discoloured with urine and yolk, and will not scour to a near-white colour. Some common stains include pizzle (urine) stain, pen stain, bacterial stain, canary yellow, dip stain and water-rot stain (see Appendix 26).
Staining scale rating
Staining rating calculated from an observed difference in colour between a test and a reference specimen. The rating is used in assessing stains due to branding substances remaining on the wool after scouring.
Stain resistance
Ability of a fabric to withstand permanent discolouration by the action of liquids. This property depends on the chemical nature of the fibre, but it can be improved by proprietary treatments, called stainblockers.
Stag
A ram castrated after about six months of age.

Stand Area immediately surrounding an individual shearing machine – the shearer’s allocated work space. For example, a four-stand shed provides space for four shearers.
Standard conditions
The standard atmosphere for testing wool and wool products is 65% + 2% relative humidity and 20oC + 2oC temperature. (See Conditioning Atmosphere)
Standard deviation
Measure of variability in a distribution of test results. For example, for fibre diameter, the standard deviation indicates how the diameters of individual fibres in a test specimen vary from the mean value. Standard deviation is the square root of the variance and is expressed in the units of measurement, eg, microns. (See Coefficient of variation)
Staple
Wool fleece- Well-defined aggregation of wool fibres growing in bunches, or clusters and also known as locks, each of which is held to the adjoining locks by binders or fibres running obliquely from one staple to another in the fleece. Wool preparation – To bring fibres to a certaint uniformity in properties, usually length, for example by sorting.
Staple base
Bottom of the wool staple that represents the portion of the wool staple where it has been cut directly adjacent to the skin surface.
Staple fibres
Fibres with a finite length (eg, 20-200mm) such as wool and cotton, as opposed to continuous filaments (extruded man-made fibres and silk). Man-made fibres can be converted from filament into staple form for blending with wool and other fibres by cutting or stretch-breaking.
Staple length
Measured length of the staple from tip to base (or butt). For a sale lot, a minimum of 55 staples must be measured by the ATLAS instrument to conform to the IWTO standard. The average staple length is then calculated and reported in millimetres (mm).
Staple length variability
Refers to the variability in staple length within a sale lot. It is reported as the coefficient of variation, which is expressed as a percentage (CV%).
Staple measurements
Refers to measurement of staple length (mm), staple strength (Newtons/kilotex), staple length variability (Coefficient of Variation %) and position of break (POB), as measured by the ATLAS instrument.
Staple strength (or Tensile strength)
Maximum force required to rupture a staple of given thickness (kilotex). Staple strength is expressed in newtons/kilotex (N/ktex). It is measure of tensile strength which is independent of mean fibre diameter and average thickness of a staple. Poor staple strength results from wool tenderness, which usually arises from pathological (eg, fly strike), nutritional or other environmental stress. Staple strength results around 10 - 20 N/ktex indicate very tender wool while results around 50 N/ktex indicate very sound wool. (See ATLAS)

Station
Originally the hut, yards and buildings where a squatter was based, now refers to the while property. A large rural establishment for running sheep or other livestock. In New Zealand it is a very large farm in hill country or the high country. The term is widely used for any property carrying over 2500 – 3000 sheep.
Steaming
Treatment with steam to achieve a variety of results in finishing. For example, blowing steam through a wool fabric tightly wound onto a perforated beam improves the lustre of the fabric. A steamer is mostly used.

Such machines are used for drying, heat-setting or the fixation of chemical finishes on fabrics. The term “being on tenterhooks” originated from the hooks that fix the fabric to a tenter frame.
Stepped opener/blender
Machine used in a wool scour for opening, cleaning and blending of scoured wool after it is dried. Wool enters the machine and is carried upwards by a series of spiked drums to facilitate opening and mixing. A concave screen under each drum allows dust and dirt to be sucked though by fans and removed.

Straightbreds Sheep with the obvious characteristics of a breed, but which are not necessarily registered with the breed society.
Strain
Line of sheep, within a breed, bred with certain distinctive features. A genetically distinct group of animals that does not qualify as a breed.
Streak
Abnormal, discontinuous stripe in a carpet (or fabric) where a yarn differs from its neighbours because of a colour difference, soiling, twist differences etc. (See Stripe)
Stress
Any physical or psychological event that has a detrimental biological effect on an animal. Stress-strain curve (or Load-extension curve)
A graph which depicts the tensile strength of a fibre, filament or yarn. It is obtained by measuring the strain (amount of stretch) as a force (load or stress) is applied. For wool fibres, the stress-strain curve can be divided into four distinct regions:
1. Decrimping: the initial stress removes any crimp from the fibre, ie, straightens it.
2. In the Hookean region (up to 1% extention) the strain is proportional to the stress, so this part of the graph is linear. Here the alpha helices in the microfibrils are extended, a reversible step.
3. In the yield region (2 to 25-30% strain), there is a considerable increase in strain (extension) for only a small increase in stress (ie, the fibre stretches very easily). Here the alpha helices are being unfolded, and being converted to beta keratin in an irreversible step.
4. In the post-yield region chemical bonds begin to break and the resistance to stress increases significantly (ie, the fibre stiffens).
5. Finally, the fibre ruptures at a strain that depends on the moisture content of the fibre. The shape of the stress-strain of a wool fibre and how far the fibre can stretch before it breaks depends on its moisture content. (See the graph “Stress-strain curves of wool” in Appendix 31)
Stretch break

Nominal tares for conventional synthetic and jute wool packs are agreed from time to time and a scale of nominal tares is published. The customary deduction for jute packs is 4 kg and for synthetic packs 2 kg.
Tartan
Woollen or worsted fabric with a plaid design, originating from Scotland. Tassels
Greasy locks of wool left by the shearer under the legs and brisket of a sheep. Tattoo
Permanent distinguishing marks made in the ear of a sheep by rubbing pigment into small punctures in the skin. Team

TEAM (Trials Evaluating Additional Measurements)
This Australian project conducted trials in topmaking plants over a number of years using fine wool processing consignments that have been measured for fibre diameter, staple length and strength and vegetable matter content. The results have enabled formulae to be developed to enable the processed fibre length (ie, Hauteur of the top) and the waste produced in combing (noils) to be predicted from the measured properties of the wool used.
Tear
Ratio of the amount of top produced to the amount of noil produced during the combing process. See also Romaine.
Teaser
Vasectomised ram used to indicate which ewes are ready to mate. It is placed in a paddock near ewes to encourage them to cycle prior to mating. A teaser ewe is used to stimulate rams to ejaculate for semen collection.

Used to raise the surface fibres of woven cloth. Traditionally the dried seed head of the Fullers’ Thistle plant was used as it contains many hooks.
Technical textiles
Textile products manufactured for non-aesthetic purposes, where function and performance are of prime importance. They include automotive applications, medical textiles, geotextiles, agrotextiles and protective clothing.
Teeth
Sheep have two types of teeth, incisors and molars. Temporary incisors appear soon after a lamb is born and within a month the complete set of ‘milk teeth’ are present. Until the age of four years (when all the adult teeth have erupted) it is possible to tell the age of sheep from their front teeth, as a pair of incisors erupts each year. Mature sheep have 32 teeth (dental formula: I:0/4 C:0/0 P:3/3 M:3/3). As with other ruminants the eight incisors are in the lower jaw and bite against a hard toothless pad in the upper jaw to pick off vegetation. Sheep possess no canine teeth, instead there is a large gap between the incisors and premolars.
The front teeth are gradually lost as sheep get older, making it hard for them to feed and affecting the health and productivity of the animal. For this reason, sheep on normal pasture begin to slowly decline from four years on. The average life expectancy of a sheep is 10-12 years but some sheep may live as long as 20 years.
Teg
See Hogget. Tel Quel
Trading term for the practice of trading wool on the basis of knowledge of its type (or the appraisal by the buyer) and without reference to specific yield or other parameters. There is no warranty by the vendor other than what the goods are said to be at the time the contract is made. Often used with reference to slipe wool. Also called ‘as-is’.
Tel Quel weight
Expression is used in a wool selling transaction to indicate that the weight to be delivered is the net weight and not conditioned weights. Therefore moisture content is not taken into account.
THE EWENIQUE GLOSSARY OF SHEEP & WOOL TERMS
© AgResearch 2012 137
Tenacity Measure of the strength of a yarn where the breaking load (in Newtons) is divided by the linear density (or count) of the yarn (in tex). The result, expressed in Newtons per tex, enables the strength of yarns with different linear densities to be compared. Sometimes the unit grams per tex (g/tex) is used.
Tender
Wool for which a significant proportion of staples exhibit a marked tensile weakness along a portion of the staple length due to an interruption in their growth. Greasy wool is subjectively assessed by pulling staples to test their resistance to break. The ATLAS instrument provides an objective commercial test for staple tenderness. (See Staple Strength, ATLAS). Wool that has a tensile strength less than 20 N/ktex is regarded as tender, while wool with a tensile strength around 20 N/ktex is regarded as part tender. (See ATLAS, Staple strength)
Tentering

Tint Colouration that produces a very pale shade. A tint usually represents the minimum amount of colour that will give a perceptible appearance of colouration. In yarn processing, fugitive tints are used for identification, then removed in wet processing.
Tip Defined as the outer extremity of a staple of wool, opposite to the end shorn from the sheep (the base or butt). The tip usually contains dust and degraded grease, and is weathered by exposure to sunlight etc.
Tip length
Number of millimeters from the staple tip to a point where the staple width is 75% of the staple width. Longer in crossbred wools (with tippy staples) than finer wools (with more blocky staples).
Tippy
Wool with a very pointed tip to the staple. A loose open tip affected by weather damage. (See Blocky). Tip shearing
Shearing off tufted high loops in a carpet during the finishing process to create a cut/uncut texture in the pile. Light tip shearing may be used to remove any fuzzing on the pile surface. (See Finishing)

(a) A substantially parallel formation of the fibres, essentially free of vegetable matter,
(b) The absence of fibres so short as to be uncontrolled in the preferred system of drawing,
(c) A substantially homogeneous distribution throughout the sliver of fibres from each length group.
Tops are specified by their fibre diameter, fibre length distribution, regain, etc. (See Topmaking, Gilling, Combing) Top dyeing

TruTrac Finishing process developed by WRONZ to eliminate the risk of shading (pile reversal or watermarking) in wool carpets. Heat, moisture and pressure is applied to the pile to ensure that the tufts lean consistently (and permanently) in one direction. (See Shading)
Tube
Metal down-tube that carries the flexible drive shaft for the shearing handpiece. Tucker
A New Zealand slang term for food, often used on the farm and in shearing gangs. Tuft
Cluster of fibres drawn through a fabric and projecting from the surface in the form of cut yarns. This U-shaped section of yarn with two legs is the basic unit of a cut pile carpet. In tufting a tuft is produced by the single penetration of the primary backing by a threaded needle.
Tuft bind
The force (in Newtons) required to pull a tuft from the pile surface of a carpet. This indicates how well the tuft is held in place by the latex. Tuft bind is a common test for wool carpets. (See Yarn encapsulation)
Tuft definition

Tufting
Most widely used, and fastest, method of carpet manufacture. The pile yarns are inserted into a primary fabric backing by a row of a hundred or more needles, one for each line of tufts (or loops). The tufts (or loops) are anchored in place by applying an adhesive coating. A secondary backing of fabric or latex or plastic foam is applied for added strength, dimensional stability and improved appearance. This method was first used commercially in 1946. (See Needle bar, Appendices 17, 18)

Turning cradle
Restraining device that squeezes the sheep from the front and rear until all feet leave the gound. The sheep is then pivoted upside down by rotating end over end.
Turning tail
Behavioural fault in a sheepdog where it turns away from the sheep in a complete circle. It fails to “face-up” to the sheep all of the time.
Tussock
Prior to European settlement in New Zealand, most of the eastern South Island was covered with vast areas of tussock, which contained grasses and herbs palatable to sheep. This provided instant pasture. There are four types of tussock – red, snow, silver and fescue.
Tussock jumpers
Station hands. Twenty striker
A badly shorn sheep.

Tweed Originally a coarse, heavyweight wool fabric for outerwear, woven in Southern Scotland. Tweed is the Scotch name for twill and originated along the banks of the Tweed river, which separates England from Scotland. The term now applies to fabrics made in a wide range of weights and qualities from woollen spun yarn in a variety of weave effects and coloured patterns. It is sometimes known as "tweel" and is similar to homespun Cheviot and Shetland. They are the same in texture, yarn, weight, feel, and use. Tweed was originally only made from different coloured stock-dyed fibres, producing various colour effects. The tweed fabric family consists of a wide range of rough surfaced, sturdy fabrics. There are also some closely woven, smoother, softer yarn fabrics, and many monotone tweeds. Tweed may also be plaid, checked, striped, or have other patterns. It does not hold a crease very well. Typically used in a wide range of suits, coats, and sportswear for men, women and children.
Twill
Weave pattern that shows distinct diagonal lines generally running from bottom left to top right on the face of the fabric. Twills may be broken, which will produce short diagonal lines.
Twist
Sheep: The crutch, inside the hind legs of the sheep. Yarn: Number of turns per metre (tpm) in a yarn.
Twist direction
Yarn twist is described as S or Z, according to which of these letters more closely matches the alignment of the fibres when the yarn is held vertically. The alignment is compared with the direction of the central stem of these letters to determine what the twist direction is.
Twisting
Process which twists two (or more) singles yarns together to produce a two-fold (or higher) yarn. Sometimes called plying or folding. This may be achieved by ring twisting (using a similar action to a ring spinning frame) or two-for-one twisting (See Two-for-one twisting).
Twist factor (or Twist multiplier)
Measure of the yarn twist that is independent of the count of the yarn. It is calculated as the product of the twist (in turns per metre) and the square root of the yarn count.
Twist-lively
Very highly twisted yarn that tends untwist spontaneously and hence will snarl or twist around itself when free from tension.
Twist-on-twist
Folded yarn in which the direction of the folding twist is the same as the direction of the singles twist. Such yarns tend to be less stable than yarns where the direction of the folding twist is opposite to that of the singles twist.
Twist setting
Process applied to yarn to set or lock in the twist to prevent unraveling of the plies (important for cut pile carpets).
(See Setting, Chemset) Twistset
See Chemset. Twitty
Irregular yarn in which local concentrations of twist in the thinner sections emphasise the irregular appearance. Two-for-one twisting
Spinning process which inserts two turns of twist for each revolution of a twisting element. This is achieved by inserting one turn of twist between a stationary feed package and a rotating disc, and a further turn between the disc and a balloon guide.
Two-phase model of wool
This simple model describes the internal structure of a wool fibre in terms of flexible filaments embedded in an amorphous matrix material. This is similar to reinforced concrete where embedded steel rods give strength and flexibility to the concrete.
Two tooth (or Yearling)
Sheep having two incisor teeth and approximately 12- 19 months old. Other age groups are – Four-tooth: 18-24 months old; Six tooth: 23-26 months old; Eight-tooth: 24-48 months old.
Tying
American practice of packaging shorn wool. After the fleece is removed from the sheep it is rolled into a neat bundle and tied with a wool tie. The tie is string or twine made of paper.
Type
Refers to the subjective characteristics which distinguish wools within breeds, as well as between breeds (eg. Down type, fine Merino type, etc.).

Strain of Merino sheep imported into Australia from America in the 19th century. Unfortunately they gradually changed from plain-bodied sheep to heavily wrinkled animals with low-yielding wool. Their uneven wool quality and a high fly strike risk was disastrous for the wool industry and led to the eventual demise of this breed.
Vertical integration
Involvement of a company at more that one stage of the wool marketing and processing chain. Vicuna
A small camelid, related to the alpaca and llama, and is found only in South America. Its fibre is a short, soft, exceedingly fine fibre that is very valuable because of its limited supply (it was once killed almost to extinction). The fibre is rarely used by itself, and is is sometimes mixed with wool to produce special soft coating fabrics. (See Camelid)
Virgin wool

© AgResearch 2012 146
Weaning Removing lambs from their mother to terminate the suckling period.
Weathering
Exposure of the wool, particularly the staple tips to sunlight, rain and frost not only weakens the wool but also affects its dyeing properties, making for uneven dye uptake.
Weavable singles yarn
A singles worsted wool yarn produced for the weaving of fine light-weight fabrics. It is specifically made to withstand the abrasive forces of the weaving operation, usually a problem with conventional singles weaving yarns (see Solospun).
Weave
Pattern of interlacing of warp and weft yarns in woven fabrics. All weaves fall into 3 basic types – plain, twill and sateen – depending on the yarn interlacing pattern.
Weaving
Interlacing of warp and weft yarns to produce woven fabrics. On the loom the warp yarns are raised or lowered to create a space (the shed) through which the weft yarn is inserted. The four steps in the weaving cycle are (1) shedding by the heald frames, (2) weft insertion, (3) beating up by the reed and (4) let-off by the warp beam and take-up by the cloth beam. (See Appendix 16, Shed, Weft Insertion)

Australian term for plucking wool from a sheep that has been missed by a shearer. Weft
The set of threads running across the width of a woven cloth or carpet, which are inserted by the shuttle in weaving. Weft yarns are not subjected to the same strain as warp yarns and thus can be spun from less sound wools. An alternative name in USA is filling; in the UK the alternative terms woof, shute and shoot are also used. (See Appendix 16, Warp)
Weft insertion (or Picking)
Several alternative devices are used to insert weft yarns through the shed of a weaving loom. They include a shuttle (the traditional device), the rapier, projectile, air jet and water jet. (See Weaving, Appendix 16)
Weft knitting
Method of forming a fabric by normal knitting means, as opposed to warp knitting. Loops made by each weft thread are formed across the width of the fabric. Hand knitting using a pair of knitting needles is one kind of weft knitting. Machine weft knitting can be divided into three types:

- flat knitting (or V-bed knitting)
- circular knitting Wefty
Wool of poor tensile strength more suitable to the production of weft yarns only. Weighbelt
Conveyor with facility for continuously weighing the quantity of fibre on it. Weighing (wool bales)

Wet graft
American term where the lamb to be grafted, as well as the ewe’s own lamb, is immersed in a saturated salt solution.
Wet shearing
Shearing of wet ewes, ie, ewes with lambs at foot and “in milk”, or ewes whose lambs have not long been weaned. Wet shorn
Shorn wool containing moisture – can arise in heating after pressing and brown burn stained wool. Wetting agent
See Surfactant, Detergent. Wheat/sheep zone
The main production zone for wool in Australia, and includes areas that are generally equally suited to cropping and the raising of animals, often in combination. The seasons are generally reliable in terms of seasonal rainfall, and are found in state of Australia. (See High rainfall zone, Pastoral zone).
Whelping
To produce a litter of pups. A whelp is another name for a pup (or the young of a mammal). Whipping side
Last side of a sheep to be shorn with long blows. White muscle disease
Sheep disease caused by a deficiency of selenium, vitamin E or both. It causes degeneration of the skeletal and cardiac muscles of lambs.

White-washing
Shearing of young lambs, where just enough wool is removed to make the sheep’s fleece white. Wicking
Dispersing or spreading of moisture or liquid (usually perspiration) through clothing fabric, as the result of capillary action of closely spaced fibres. It involves only the surfaces of hydrophilic fibres in the fabric and does not include absorption. The wool used in SportwoolTM is specially treated to enhance its wicking performance.

Willey To open and disentangle fibres prior to scouring or carding. Also the name of the machine that carries out this process. (See Opener, Fearnought)
Willow
Machine for removing dirt and dust from wastes, particularly card waste. Fibres that have been processed on a willow are termed willyed. Originally, the willower beat raw wool manually with willow twigs to remove dust and dirt. By the end of the 18th Century a water driven willowing machine, called a willow or willyer was used to help remove burrs. The wool was passed over iron spikes on a roller. This was not as good as the hand treatment as it was too harsh on the fibres.
Wilton carpet
Woven carpet in which the pile yarns run continuously in the warp direction of the carpet. The pile consists of rows of loops formed on wires which run across the machine. The wires are withdrawn leaving a loop, traditionally called Brussels or tapestry carpets. Alternatively a bladed wire can be used which cut the loop as it is withdrawn to produce the true Wilton style. The pattern is made by raising the colour in the pile as required, with the colour not required being buried in the backing. Having to carry unseen (‘dead’) yarn through the back adds to the cost, so, generally speaking, Wilton carpets use no more than 5 colours in their designs. Wilton carpets tend to have a dense construction and are therefore very durable. (See Appendix 33)
Winch (or Reel, Wince)
Dyeing machine in which one or more endless lengths of fabric are drawn through the dyebath by a rotating reel or drum above the dye liquor.
Winder
Machine used for transferring yarn from one package to another to facilitate subsequent processing. The process is called Winding.
Winter comb (or Cover comb)
A thicker shearing comb designed to leave more stubble at shearing to give a degree of protection to the sheep when shorn at cooler times of the year. An alternative to shearing using blades.
Winter country In farming sheep in the New Zealand high country, the sheep are mustered from the ‘tops’ in autumn and held in paddocks during the winter. Here, in the winter country, root crops and other supplementary feed can be available for the sheep.
WIRA Carpet Abrasion Tester
Laboratory device (developed by the Wool Industries Research Association, UK) which uses a rotational motion to rub a small disc of carpet (the specimen) against a standard abradant fabric for an extended period to assess its abrasion resistance. The result is obtained by either of two methods:
- determining the ‘number of revolutions’ required to reach the end point, where the backing of the specimen is just exposed;
- measuring the mass of pile lost from the specimen per 1000 revolutions of the tester. WIRA Fibre Diagram machine
Laboratory instrument for measuring the fibre length of wool slivers and tops. The fibre diagram is obtained by optically scanning an aligned tuft of fibres, called a fibre draw. The machine provides results similar to the Almeter system, but these are generally less accurate. (See Almeter)
Wire loom weaving
See Brussels carpet, Wilton carpet. Withdrawn lot
A lot listed in the auction catalogue which is notified as being taken out of the offering before the auction commences.
Wither
Part of the sheep between the shoulders. Withholding period
Period of time during which an animal (or its product) may not be used for processing or human consumption, after it has received a treatment such as a drench, antiobiotic or dipping. In New Zealand, the recommended withholding period between the dipping and shearing of sheep is 60 days.
Wolseleys
Early term for machine shears because Frederick York Wolseley invented the first shearing machines. Woof
American term for the yarn that runs across a weaving loom (see Weft)

Wool Fibre from a sheep’s fleece, composed of keratin protein. The term "wool" can also apply to all animal hair fibres, including the hair of the Cashmere or Angora goat or the specialty hair fibres of the camel, alpaca, llama, or vicuna. The exterior of wool and related fibres is characterised by its overlapping surface scales, called the cuticle. Wool is very resilient and resistant to wrinkling. It is renewed by moisture and well known for its warmth. It absorbs and releases moisture slowly, which allows excellent insulating capabilities and breathability. It can even hold 30% of its own weight without feeling damp.
In other languages wool is: French – laine German – wolle Greek – lenos Italian – lana Spanish – lana
Wool is also a town in Dorset, England. The term ‘woo’ is used in the north of England. Wool (derogatory term)
A term used for people in various parts of the United Kingdom, for example, an uncouth person from St Helens, one who lives in the Wirral, and people from Lancashire and Cheshire. Used by people from Liverpool to describe people from nearby areas. A person is called a ‘wool’ when they do something embarrassing. It is thought to be a shortened version of the term ‘woolyback’ (see Woolyback)

Wool-filled products
Products, usually bedding (eg, duvets and futons) and apparel, filled with wool which is usually carded into a batt or thick web of fibres, or is in the form of soft knops.
Wool gauze
Lightweight, opaque wool fabric suitable for wearing all year round. Woolgrease
Natural impurities of wool (wax and suint) secreted by glands attached to the wool follicle. Also called yolk. It is more usual to refer to this substance as wool wax when it is on the fibre, and wool grease when it has been removed by scouring.
Wool grower (or Wool man)
A sheep farmer. Wool handling
Sorting, skirting and preparation carried out between the shearing and pressing operations in a shearing shed. This is carried out by a wool handler (or fleece picker up, or board boy).
Wool harvesting
The entire operation, from shearing to baling. Woolled up
When the shearer's output exceeds the ability of the wool handler's, classer or presser to keep up. Also described as snowed-in. The term is also used when wool gets caught up in a shearer’s down-tube or in the back joint of the handpiece, causing overheating of the equipment. (See Snowed in)
Woollen count
The two systems used to determine woollen yarn counts in the U.S. are the run system and the cut system. The run system has a standard of 1600 yards per hand, while the cut system is based on 300 yards per hank.
Woollen processing (or Woollen system)
Simplest of the three main routes for converting wool into yarn. It uses a wide variety of wools, including those that are relatively short and tender. It combines three processes – carding/condensing, spinning and twisting. The woollen route produces a relatively bulky and hairy yarn, because the yarn is comprised of fibres that are comparatively randomly oriented (ie, not well aligned) within the twisted yarn structure. (See Appendix 7)
Woollens
Fabrics produced from woollen spun yarn. Woollen yarns are generally manufactured from short length wools which have been carded, condensed and spun. In the finishing processes the weave of a woollen cloth is largely obscured and frequently the cloth is milled or felted. These cloths have soft-surface textures and finishes. Tweeds and meltons are some popular examples of woollen fabrics.
Woollen yarn
Yarn produced by woollen carding and spinning and which is more bulky and fuzzy than semi-worsted and worsted yarns. These characteristics carry through to the texture of the fabrics and knitted garments (see Appendix 7).
Woollies
Sheep not yet shorn. Woolly hogget (or Woolly hog)
Fleece off a hogget which was not shorn as a lamb. Woolmark
Registered international trademark denoting products made from pure new wool, which also meet strict performance criteria. Replaced by the Fernmark (or Wools of New Zealand brand) wool carpets containing predominantly New Zealand wool. (See International Wool Secretariat, AWI)

Worker
Slowly rotating roller on a carding machine that interacts with the swift to open and blend the tufts of fibre presented to it. These rollers operate in sets of three or four set close to a swift roller and each worker is accompanied by a stripper roller. The delay in wool flow caused by the workers facilitates blending. (See Stripper, Swift, Working action, Appendix 10)
Working action
Interaction between a worker roller and a swift on a carding machine, involving a tooth-to-tooth action. Tufts of fibres carried by the swift past a worker may be captured by the worker, and the tuft separates into two parts. The portion held on the worker is carried by this roller to a stripper, that delivers the fibres back to the swift after a brief delay. (See Appendix 10)
Working dog
Dog that works with a shepherd to move and gather sheep. Wormer
Commercial product containing an anthelmintic to control internal parasites (see Drench). (See Anthelmintic) Worrier
Dog that chases, attacks or kills sheep. Worshipful Company of Wool Men

It was known to have existed in 1180, and officially incorporated in 1522, making it one of the oldest Livery Companies. The Company’s original members were concerned with the winding and selling of wool; today the Company is primarily a charitable institution but retains a connection with the industry by supporting education in wool.
Worsted count
A wool yarn measure in the USA. A 1s worsted yarn has 560 yards in one pound of yarn. Worsteds
Fabrics produced from worsted-system yarns. Wool fibres (usually fine) have been scoured, carded, gilled and combed before spinning. This term usually refers to tightly woven, smooth, clear-finished goods in a variety of constructions including plains, garbardines and serges.
Worsted processing (or Worsted system)
Yarn manufacturing route which uses mainly the longer stapled wools. These are carded, then gilled to align the fibres and combed to remove the noils and vegetable matter and gilled again to straighten the fibres. The final untwisted strand of fibres, the roving, is ring-spun at high draft to produce a smooth, fine yarn. The term ‘Worsted’ is a slight corruption of Worstead, the village in Norfolk where expert cloth-workers who entered England in the early 14th century brought with them new methods for producing a quality cloth. There are three basic systems of worsted yarn spinning: The Bradford (or English) system, the French (Alsatian or Continental system) and the American system. (See Noils, Romaine, Tear, Topmaking, Appendix 7)
THE EWENIQUE GLOSSARY OF SHEEP & WOOL TERMS

Worsted yarn Strong, fine, spun thread in which fibres have been straightened by gilling and combed to remove short fibre neps and vegetable matter before spinning. In worsted yarn the fibres are more parallel and tighter spun, resulting in smoother, stronger yarn than the woollen system. The fabric produced is smooth, dense and retains its shape well. Products from the worsted system include suitings and knitwear (see Appendix 7).
Woven
Fabric characterised by the interlacing of warp and weft yarns. Woven carpet
Carpet in which the pile is woven into the backing fabric on a loom (ie. Axminster, Wilton, Face-to-Face and hand-knotted). Weaving is slower and more expensive than tufting, but offers a wider range of coloured design options. (See Appendix 33)

Y Yan tan tethera
Traditional numeric jargon once used by shepherds in Northern England and Scotland for counting sheep. Numerous systems were used in different areas – Yan, tan, tethera are one, two, and three respectively in the Derbyshire Dales and Lincolnshire counting systems. These counting systems were ultimately derived from the Celtic language. The yan tan tethera system was also used for counting stitches in knitting.
Yards Catching yard – small yarn to enable sheep to be caught, eg, for shearing (sometimes called a catching pen). Holding yard – for keeping sheep together in preparation for shearing or some other operation. Temporary – erected or transported for special tasks such as lamb marking.
Yarn Fibres twisted together during spinning to form a continuous strand with sufficient strength to withstand the stresses of weaving, knitting or tufting processes without breaking. A single strand is called a singles yarn while twisting two or more singles yarns together produces a plied or folded yarn. For wool, the three types of yarn are woollen, worsted and semiworsted (see Appendix 7).
Yarn count See Count.
Yarn encapsulation
Extent to which the yarn on the back of the primary backing of a carpet is surrounded by, and infused with, latex before the secondary backing is applied. (See Backcoating, Tuft bind)
Yarnspec
Computer software package for the prediction of worsted spinning performance, developed by CSIRO.
Yearling One year old sheep.
Yellowness Degree of creaminess or yellowness in a wool, see Colour, Yellowness.
Yellowing When exposed to sunlight wool turns yellow, particularly when the wool is wet and with an alkaline pH.
Yield Amount of clean fibre in a lot, at a standard regain expressed as a percentage of the weight of greasy wool in that lot. There are 6 alternative IWTO core test yields that can be calculated from the wool base for commercial trading purposes.
1. Schlumberger Dry Top and Noil Yield (SCH DRY) The most commonly applied yield, it estimates the amount of top and noil that can be combed from the greasy wool. Allowances are made for moisture regain, residual fatty matter and dirt and a processing allowance (ie. an allowance of fibre loss) which is dependent upon the amount of VM (less hard heads) in the lot. This is the yield most used in valuing wool.
The IWTO Schlumberger dry combed tested yield predicts the yield of a wool after it has been combed on a Schlumberger comb without the addition of processing oil. It is based on the production of 8 parts combed sliver (top) to one part short fibre (noil) with an allowance for fibre loss.
2. IWTO Scoured Yield 17% Regain (CD 17%) This is the washing yield. It represents the product after scouring, before any further processing takes place (ie. includes VM plus wool). Allowances (2.27%) are made for residual grease and residual dirt. A regain of 17% is used. (IWTO scoured yield is also available at 16% regain).
3. Japanese Clean Scoured Yield (JCSY) This is a washing yield which is similar to above except that the regain of 16% is used with a lower allowance (1.5%) made for the scouring residuals. Also this yield has the vegetable matter deducted but no allowance is made for fibre loss during processing. This yield is the basis for trade with Japan.
4. IWTO Clean Wool Content Yield 17% Regain
Calculated from wool base which is adjusted initially to contain the standard allowance of 2.27% for ash and alcohol extractives and finally brought to a regain of 17%.
5. Australian Carbonising Yield 17% Regain (ACY) Calculated from wool base and vegetable matter base and allows for the expected loss of fibre during the carbonising process. It is widely used as the basis for trade in carbonising and carding types.
6. ASTM Clean Wool Fibre Present Calculated from wool base which is adjusted initially to contain the standard allowance of 2.27% for ash and alcohol extractives and finally brought to a regain of 13.64%.

Yoe Early shearer’s term for a ewe. The terms yow and yowe are also used in some areas of England. The term ‘yowens’ refers to ewe lambs.
Yoke Two crossed pieces of timber, or a forked branch, fixed to the neck of a habitually-straying sheep to prevent it breaking through hedges and fences
Yolk
Combination of the secretions of the wax and sweat glands which adheres to the wool fibre. Erroneously termed wool grease - hence the term 'greasy wool'. It is removed by scouring. Desired yolk is clear while undesirable yellow types are termed cakey, suety and fatty yolk. Yolk stain is a wool stain caused by pigment from the yolk.
Yolk stain A stain caused by pigment from the yolk.
Yurt A circular dwelling with a domed roof widely used in across Asia from Turkey to Mongolia. Thick wool felt is lashed onto a wooden frame to provide protection from the elements. The felt is produced by first placing a layer of wool on dampened felt and wetting it. Then the whole package is wrapped around a pole, covered with a yak skin and dragged bouncing behind a horse for several hours to consolidate the wool into a dense felt.
Lincoln Large body with long, coarse, lustrous wool which hangs over the face from the poll; white face, wool on legs down to feet; black
hooves.
Body weight (kg) 55 – 70 (ewes)
Fleece weight (kg) 7 - 12
Staple length - annual growth (mm) 175 – 200
Fibre diameter range (mm) 37 – 41+
Lamb production (%) 100 – 130
A breed that was well-adapted to grazing on pasture which had been recently cleared of forest in the early days; hence it was
once second in popularity to the Merino. As the soil fertility dropped this breed did not thrive as well, and from 1900 the Lincoln
was gradually replaced by the Romney. Today this dual-purpose breed is farmed throughout NZ and is mainly used for creating
crossbred ewes. Lincoln wool is used for products requiring lustre, soft handle and high strength. Products include upholstery yarns,
carpets, hand-knitting yarns and wigs. It is also blended with mohair.

Staple length - annual growth (mm) 150 – 200
Fibre diameter range (mm)
37 – 40
Lamb production (%)
100 – 150
A dual-purpose breed, mainly used for creating crossbred ewes and first-cross Halfbred rams. Used to improve wool weights and
fertility in other breeds. It has a similar history in New Zealand and fleece characteristics to the Lincoln. Around 1900 it was the
third most popular breed. Flocks began to decline, although the breed is still crossed with Merinos to produce the New Zealand
Halfbred. The heavy, curly lustrous wool is even in length and diameter. Linings for suits, coats and furnishing fabrics are among
the end-uses for English Leicester wool.
