INTRODUCTIONy To survive and thrive in the competitive today s business world, latest

developments in textile testing plays a vital role.y These high speed manufacturing machines require much cleaner raw material,

and therefore they constantly challenge the testing machinery developers to provide faster and more accurate testers and quality controllersy Textile industries need for analysis of any type of measurement like length, area,

count of any fine textile fiber can be done for textile fiber & fabrics to fulfill better quality of products.

IMPORTANCE OF TEXTILE TESTING INSTRUMENTSy In the present textile scenario, textile materials should furnish better

quality, good aesthetic, durability and performance for user. Since for this, testing of textile materials are significant to yield better quality and marketability

CLASSIFICATION OF TESTING INSTRUMENTSBasically the testing instruments are classified into three categories y Fiber testing instruments y Yarn testing instruments y Fabric testing instruments

FIBER TESTING INSTRUMENTS

y Fiber testing instruments are used to find or to determine the various properties ofthe fiber such as staple length, fineness, nep count, strength, trash content etc. some of the modern instruments available in the market are

y Digi Vision Projection Microscope, Uster HVI 1000

YARN TESTING INSTRUMENTS

Yarn testing instruments are used to find or to determine the various properties of Yarn such as twist, Strength, Elongation, Count, Evenness etc. some of the modern instruments available in the market are Yarn Tension Meter, Digital Yarn Tension Meter, Twist Tester (Single Yarn)

FABRIC TESTING INSTRUMENTS

Fabric testing instruments are used to find or to determine the various properties of the fabric such as bursting strength, tearing strength, Tensile Strength, Darpeability, Air & Water Permeability etc.

Some of the modern instruments available in the market are digital MiniMartindale, Dynamic Air Permeability Tester

HVI 1000FEATURES

It measures all the important quality parameters currently used by textileindustries such as Micronaire, fiber length, length uniformity, strength, color, and trash.

Additional information on short fibers, cotton maturity and sample moisturecontent are also evaluated.

700 samples can be tested per 8-hour shift

USTER AFIS PRO 2In Uster Afis Pro 2, any material in the form of bale, mat, sliver or roving can be tested on the, repeatedly and reliably. Blends can be tested up to a ratio of 50% cotton: 50% synthetic.

FEATURES

Basic measurements of the NC Module include theamount of cotton fiber and seed coat neps.

L&M Module measures fiber length and short fibercontent, plus cotton maturity and immature fiber content.

Trash Module measures the trash and dust contentin cotton.

Histogram Reports show the distribution of eachfiber property compared to its size group, visualizing the impact of a process on the fiber material.

DIGI VISION MICROSCOPEFEATURES Latest design computer interfaced projection microscope for fiber & yarn analysis. With maximum resolution of 1500X magnification Photos of all fibers longitudinal & cross-sectional view are loaded in software to identify thefibers without prior knowledge in the same.

Various type of measurement like length, area, count of any fine textile fiber can be done.

USTER TESTER 5-C800 (UT5)

Evenness %, Thick & thin places, neps are measured Analysis of VL-Curves, Spectrogram. With the special sensor technology, periodic or nearly periodic mass variations caused by defective rotating machine parts (such as gears from the spinning pump) can be detected with the spectrogram.

Operated at speeds up to 800 m/min with continuous adjustability

DIGITAL YARN TENSION METERPRINCIPLE

Digital yarn tension meter has a specially designed electronic sensor which is capable ofsensing tension in the moving yarn very accurately.

This sensor converts the tension read by the sensing probe into the equivalent electricalsignal. This signal is processed through the micro-controller and the yarn tension is displayed digitally in grams.FEATURES

Capacity 0 to 200gms, accuracy 1gm. Portable & handy can be carried anywhere. Smooth precision-engineered mechanism Latest model with sophisticated design

USTER TENSOJET 4FEATURES y The high performance installation USTER TENSOJET 4 can carry out fully automatic measurements with up to 30'000 tests which means 24 km of yarn per hour. y Spectrogram allows identification of periodic faults. y Fully automatic check of the whole measurement.

USTER TENSORAPID 4FEATURESy USTER TENSORAPID 4 supplies all standard test values of tensile testing and

provides in-depth analysis of yarn quality.y Spectrograms plus scatter plot help identify periodic faults. y Smart and easy operation. Automatic changer for up to 40 bobbinstesting capacity. provides massive

DIGITAL BURSTING STRENGTH TESTER

FEATURES y Fully automatic digital model y It is used to find the bursting strength of the fabric. y It is used for all type of fabrics, specially geotextile fabrics. y It is fully computerized instruments. y Hydraulic pressure is used to burst the fabric.

DIGITAL MINI-MARTINDALEIt is a fabric abrasion resistance tester with digital display.

FEATURES

The mini-martindale has a powerful drive system to overcome the high levels of friction, which are generated, when rubbing, for example, rubber gloves against glass paper.

Higher speeds for accelerated testing. Suitable for wet testing Ideal for tests generating high levels of friction Sample thickness up to 20mm Additional loading up to 1.4kg

DIGITAL AIR PERMEABILITY TESTERPRINCIPLE

The principle of the digital air permeability tester is that air is drawn through aspecified area of fabric, which is adjustable to suit specific textiles being evaluated. APPLICATIONS

Textile Fabrics Blankets Knitted or layered fabricsFEATURES

Non-woven airbag fabrics Napped fabrics Pile fabrics

Digital operation Quick and simple process Useful for quality control Precise, repeatable tests

USTER FABRISCANy USTER FABRISCAN provides with an automatic consistently objective and reproducible inspection of the fabric. y At a speed up to 120 meters per minute, dependent on the fabric characteristics, Fabriscan is capable to detect flaws and defects as small as 0.3 mm. y Automatic fault reporting and fault marking. y Non-disturbing deviation versus defects.

USTER FABRISCAN ON-LOOM USTER FABRISCAN ON-LOOM integrated fabric inspection system inspectsevery single millimeter of the fabric and checks it for defects. The scanner sensors are in direct contact with the fabric and deliver high-quality images for reliable detection of defects.

Detecting fabric defects immediately as they occur, enabling early intervention independently of human perception.

When accompanied by the On-Loom Expert system, it replaces cloth inspection.

UNIVERSAL TESTING MACHINESThe Universal Testing Machines are designed for a wide range of testing procedures including: bending (folding), compression, tensile testing, peeling / adherence, shear test, friction coefficient, tear, penetration and extraction, de-lamination, indentation and many more

FEATURES

Force Measurement: through interchangeable Load cells Force Indication/ Display: through the video monitor Measurement Precision: better than 0.5% of reading Speed Accuracy: 1% Position Accuracy/Repeatability: 0.002mm Humidity: 10-90% RH

CONCLUSIONWith advanced testing instruments, we can conclude that

In the present textile scenario, with present depression in textilefield better quality of textile products can be manufactured.

One can achieve higher accuracy with least testing time for morenumber of samples.

In this competitive global market survival with this latest textiletesting techniques, we can achieve good growth in textile field.
