Annual Report

EXECUTIVE SUMMARY

The mandate of KSSRDI is to conduct research on all aspects of sericulture

industry (soil to fabric) with special emphasis on field problems of the state of

Karnataka. One of the common objectives in all the research projects is to enhance

productivity and quality with optimized input costs. Sustainability of sericulture

ultimately depends on productivity and profitability realized by the farmers with

minimum cost of production. Therefore, during the year, special emphasis was given to

dissemination, promotion and transfer of technologies. This is achieved through a

close liaison with Department of Sericulture (DOS) and through them technologies that

are developed in the Institute are popularized to the farmers and industry, helping the

stakeholders to improve productivity and quality in mulberry, cocoon, raw silk and

fabric.

KSSRDI has three divisions, viz., Moriculture, Sericulture, Silk Technology and

an Extension and Training Unit. To address the main mandate of the Institute, each

Division has identified important thrust areas on which research projects are proposed

and approved by the RAC.

The salient activities, recommendations and technologies developed during the year

2012-13 are;

Popularization of new mulberry varieties „Suvarna‟ and „Vishala‟, more than

60,000 saplings and 16.5 tons of cuttings were supplied to farmers for

multiplication. Both the varieties have been widely appreciated and are in

great demand from the farmers.

Soil fertility maps of Tumkur district have been prepared, this helps the field

functionaries to identify suitable regions for mulberry propagation and also

need based fertilizer utilization.

In mulberry pathology and microbiology emphasis has been laid to develop

bio-control methods for various mulberry diseases. During the year, a bio-

control method to contain mulberry root rot was taken up. On-farm trials to

study the efficacy of potash mobilizing bacteria have been initiated. The

licensing formalities for commercial production of these two products have

been initiated.

More than 55,000 hybrid dfls of MH1xCSR2 were distributed to the farmers

for popularization. This program is supported by CSB under their PAT

program. The layings of MH1, KS-10, BRO2, NP4, NK2 and HND were also

supplied to seed farmers for further multiplication. Studies on grainage

behaviour of new pipe line silkworm races were continued.

A model low cost rearing house using bamboo was constructed and rearing

evaluation trials were completed. This type of building significantly reduces

the initial capital investment thereby increasing the profitability of the

farmers.

A new chawki rearing method called the OFIT enables one feeding per instar

during chawki stage was evolved in the Institute and design patent was also

awarded by IPO, GOI.

KSSRDI 2012-13

Annual Report

Two new plant based silkworm bed disinfectants, „Samvardhan and „Suraksha‟

which were developed last year were field tested and recommended for

commercialization. Collaborative research work with Jain University on

application of „Nano‟ particles in silkworm disease management was initiated.

Entrepreneur development training program for mass multiplication of major

silkworm pests were completed during the year. A couple of women „Self Help

Groups‟ who have received the second level training have already started mass

multiplication program.

Standardization of design of new vacuum cocoon boiling equipment was

completed and fabrication of a pilot model is initiated for field trials. A sample

survey of silk reeling units in Ramanagaram was conducted to assess the

requirement of the reeling industry.

An eco-friendly silk and silk blends cleaning and washing method was

developed using plant based saponin which are safer than synthetic

detergents.

Studies on the effect of sized agents on silk yarn, their performance on power

loom and influence on the fabric properties was concluded and the

recommendations are now taken for field trials.

In the extension and training unit, field popularization programmes of KSSRDI

developed technologies are being implemented through two external funded

programmes. Three batches covering about 300 farmers were trained under

the CDP training program.

During the year under report, six research projects were approved by the RAC for

completion. Six new project proposals were also approved by RAC and some of the

projects are sent to funding agency requesting for research grants.

External funded research project implementation: As many as nine external funded projects are being implemented during the year. These projects are funded by DST, DBT, NAMARD and RKVY. An amount of Rs.47.32 lakh was received from the funding agency for implementation of the said projects. Licensing of technology based products: Licences for production and distribution of a number of products that are the off shoots of research work were given to entrepreneurs for large scale production and distribution to the farmers. During the year 06 products namely Seriphen, Sinchana, Samrakshaka, Bleach Check, Harith and Lime Check were licensed from the Institute for large scale production and marketing. This has helped the farmers to get the products at ease and their usage has increased the productivity and monitory benefits.

2. Project Title M-IV-2(ii): Studies on drip fertigation for optimization of yield and quality in mulberry

(Morus species) Project personnel

Project Leader : Dr.S.N.Narayan Gowda, SC Project Co-investigator : Dr.N.Siddalingaswamy, SB

Objectives: 1. To study the suitability of fertigation for mulberry to economize the nitrogen,

phosphorus and potassium inputs. 2. To improve the leaf yield and quality of mulberry leaf. 3. To find out relation between fertigation levels and leaf yield under

recommended/suitable plant densities.

Results Major observations of results of selected parameters namely, leaf yield, leaf moisture

content and bioassay parameters such as larval weight, single cocoon weight and

cocoon shell ratio are presented in Table-1. The highest leaf yield was recorded in the

treatment T6 (60 x 60 cm + drip method +100% N through drip) + surface mulching

with glyricidia (48,374 kg/ha) and lowest leaf yield was recorded in the treatment T10 -

120 x 60 cm + non mulching + 50% NPK Rec. dose. Highest leaf moisture content was

recorded on 100% N levels and lowest leaf moisture content is recorded in 50% N levels.

The highest larval weight (2.95 grams), Single cocoon weight (1.51 grams) and cocoon

shell ratio (17.77) were recorded in the treatment T6 (60 x 60 cm + surface mulching

with glyricidia +100% N through drip) and lowest larval weight (2.90 grams), Single

cocoon weight (1.50 grams) and cocoon shell ratio (17.67 %) were recorded in the

treatment T10 - 60 x 60 cm + non-surface mulching + 50% N through drip.

Recommendations

It is concluded that the effect of N fertigation was better in 60 x 60 cm spacing i.e. 27%

saving of fertilizer with an increase of 25% leaf yield over non-mulching method. In the

bioassay study the performance of N fertigated plots are better on larval weight, single

cocoon weight and CSR% than furrow method in 60 x 60 cm spacing. The study

revealed that the saving of 27% N fertilizer associated with improvement in leaf yield

and quality in surface mulching compared to non-mulching method.

Project Title

S.VI.1 Development of entrepreneurs and commercialization of bio-control agents of major

pests of mulberry and silkworm to contain the menace. (DST funded project)

Project Leader : Dr. G. Veeranna, SD

Project Investigator : Dr. E. Muniraju, SB

Year of Initiation : December, 2009.

Year of Completion : April, 2013.

Objectives:

To impart training on mass production of predatory beetle and uzi fly parasitoids

to women sericulturists from SHGs/SSGs and develop entrepreneurship in mass

production.

Releasing of bio-control agents in the identified mulberry garden and village for

demonstrating the release methods to the trainees and to collect the data on

mealy bug and uzi fly infestation to show the impact of biological control.

To assist entrepreneurs/trained personnel to establish mass production of bio-

control unit on their own or with the assistance of SHGs for mass production and

marketing of biological control agents.

Results:

Mulberry and silkworm are affected with several pests causing severe damage in terms

of quality and yield. The major pests of mulberry are pink mealy bug, Maconellicoccus

hirsutus (Green), papaya mealy bug, Paracoccus marginatus Williams and Granara de

Willink, leaf roller, Diaphenia pelverulentalis, etc. The silkworm major pest is uzi fly,

Exorista bombycis (Louis). To contain these pests, bio-control agents have been

identified and recommended to use these bio-control agents to minimize the infestation

in the field. Due to non-availability of these bio-control agents in the nearby areas, the

usage of these bio-control agents are very poor at the field level. Therefore, it was

thought to develop entrepreneurs from different intensive sericulture practicing districts

by giving training on mass multiplication of bio-control agents in the

laboratory/Insectaries and releasing method in to the field so as to facilitate to establish

mass multiplication of bio-control agents unit in different district. The sericulturists

purchase the bio-control agents from nearby areas to contain the pest menace.

Accordingly, 1st level training with demonstration and awareness programs were

organized in 4 districts viz. Mysore, Ramanagaram, Tumkur and Kolar covering 104

women sericulturists from Sthree Shakthi Group/Self Help Group (SSG/SHGs) on the

mass multiplication of bio-control agents of mulberry and silkworm pests. Besides,

information was also given to trainees on different technologies developed by KSSRDI,

Bangalore and other organizations. In the 2nd level training program, about 30 women

sericulturists were identified from the 1st level trained personnel on mass production of

bio-control agents of pests of mulberry and silkworm. In this program, trainees have

carried out the mass production of biocontrol agents on their own with the help of

project staff at KSSRDI, Bangalore. Only Tumkur district women trained personnel have

established mass production unit of bio-control agents in Hullenalli village and

marketing the bio-control agents with the help of Staff of Department of Sericulture,

GoK, Bangalore. So far, more than 10 lakhs parasitoids of uzi fly were cultured and

KSSRDI 2012-13

Annual Report

marketed @ Rs. 30/- for 20,000 parasitoids required for 100 dfls silkworm rearings in

Tumkur district.

The nuclear cultures of bio-control agents, Nesolynx thymus (Girault),

Exoristobia philippinensis (Ashmead) and Trichopria sp. of uzi fly, E. bombycis (Louis)

have been maintained on the uzi fly pupae. Mass multiplications of parasitoids of uzi

fly on the house fly pupae are developed on artificial media. In the present project, to

demonstrate the releasing methods and to determine the efficacy of bio-control agents,

two sericulture villages; one for release and other for control (without release) were

identified. A total of 85.69 lakhs N.thymus and E.philippinensis in combination were

released in the vicinity of rearing houses in the identified village against 26460 dfls of

silkworm rearings during the project period. The uzi fly infestation was recorded in the

parasitoids released and control villages. . The percent reduction of uzi fly infestation in

the released village was 52.01 (average) compared to control (Table). Besides, about

1.55 crores of above mentioned parasitoids were sent as per the indent in the form of

parasitized house fly pupae for releasing to 56785 dfls silkworm rearings of Tumkur,

Chitradura (Manakalmur) and Bellary (Kudalgi) districts to minimize the uzi fly

infestation

Similarly, predatory beetle, Cryptolaemus .montrouzieri Muls were mass cultured

on pink mealy bug developed on sweet pumpkin in the laboratory and released in the

identified as well as KSSRDI mulberry plantations to minimize the mealy bug

infestation. A total of 8715 C. mountrouzieri beetles were cultured and released in the

above mentioned areas.

The papaya mealy bug, P marginatus is a new pest of mulberry entered into

Chamarajanagara district (Karnataka) during February, 2010 and has spread to all

southern districts of Karnataka causing heavy damage to mulberry plantations in

terms of yield and quality. In the present project, integrated control method has been

suggested emphasizing the bio-control method. Awareness programs were conducted

about the management of this pest to sericulturists in those areas and recommended to

use parasitoid (bio-control agent), Acerophagus papayae was imported from Puerto

Rico. This parasitoid and predator, Spalgis epius, are the main contributors of IPM in

suppressing the papaya mealy bug population. As per our survey, the papaya mealy

bug infestation was reduced to the maximum extent due to interventions of control

methods, besides heavy rain fall in those areas, environmental conditions and also

action of naturally available predator, S. epius. Mass production of papaya mealy bug

parasitoid, A. papayae on papaya mealy bug developed on Hibiscus canabinus plants in

the laboratory. About 25000 A.papayae were released in the papaya mealy bug

infested mulberry plantations of Ramanagaram, Mandya and Chamarajanara districts.

Conclusion

About 104 women sericulturists from SHG/SSGs were given demonstration cum

training on mass multiplication of bio-control agents form four districts as a first level

training. About 30 women sericulturists from the 1st level trained personnel were

conducted the mass multiplication of bio-control agents of pests of mulberry and

silkworm on their own with the help of project staff. Tumkur district trainees

established the mass production unit at Hulenally and marketing more than 10 lakh

parasitoids to sericulturists of Tumkur dist. to contain the pest menace.

It is evident from this project finding that development of self sustainable

entrepreneurs is very much essential for mass production of bio-control agents of pests

in nearby areas to purchase the same by the stake holders (farmers/sericulturists) to

contain the pest menace. Trained personnel of this project have established the mass

2. Project title

Evaluation of plant extracts for environmental friendly cleaning /washing of silk

and silk /union fabrics.

Project Investigator : M.K. Vijayeendra, SD

Co Investigator : R. Yashoda, SB

Duration : One year

Objectives

Eco-friendly process

Exploit safe, natural washing procedure for silk.

Background: Synthetic detergents are chemically engineered products. It contains:

a) Inorganic phosphates which are environmentally dangerous.In1934, US primarily

used synthetic detergents for hand washing and dish washing.

b) Artificial colourants are made of petroleum products. They are non biodegradable,

irritable to skin & eyes, causes allergic reaction in mammals and fish (1998 C.

Sexena et al., J. Medical Aromatic Plant Science, vol. 20).

c) Optical brighteners (aminotriozine) which do not make laundry clean, but create an

optical illusion that makes fabric appear whiter & brighter. They possibly cause

reproductive and developmental problems in human. (21st edition of APHA, standard

method for examination of water and waste water, American public health

association, Washington DC).

Since ancient times, Soapnut Sikakai were used as washing laundry and hair in our

country. Silk is a delicate fiber and to make the process eco friendly and to exploit

other source of cleaning, this study was carried in association with textile engineering

students.

This study was approved by council for science and technology (KSCST) and financial

aid was provided to students.

Project Leader : V.H.Maharaddi

Project Duration : 3 Years

Year of Initiation : 2010

Objectives:

Production of coarse spun silk yarns by using basin refuse silk and its blends.

Study on blend compatibility on cotton system and evaluation of yarn properties.

Production of flat knit fabrics and evaluation of fabrics for geometrical,

mechanical properties to ascertain dimensional stability.

Methodology:

Coarse silk and bamboo blended yarns were spun on cotton system. Blend ratios are

varied from 100% bamboo and silk, 75% Bamboo; 25% silk, 50% bamboo, 50% silk and

25% bamboo; 75% silk, 2/30s spun yarns produced utilizing the facilities at Gokak

From the Table-3.1, it is seen that the trend is similar to that observed in the single

yarn. Lower strength is observed at 50/50 blend ratio. This is in agreement with the

studies made by W J Hamburger. As the proportion of silk increases to 25% bamboo/

75% silk, strength of the yarn also increases. The variation in tensile strength increases

with increase in silk proportion in the blend and is higher in case of silk yarn. This is

mainly due to higher unevenness and higher mass variation in silk yarn.

Observing the above table (Table-3.1) we can say doubling has increased the

uniformity in yarn which is apparent with the decrease in the U% on doubling. This

may be due to overlapping of thin place of one yarn over the thick place of the other

yarn in doubling, averaging the diameter of the yarn. The relatively higher level of

KSSRDI 2012-13

Annual Report

imperfections and hairiness in 100% silk yarns are largely due to the high variation in

all the quality attributes of silk fibre in comparison with bamboo fibres.

Fabric Test Results

All tests were carried out at standard testing temperature and relative humidity.

Minimum of 5 readings were taken for each test and average is determined. The results

obtained from various experiments conducted are presented below;

All fabrics have the same wale density and in course density, only one course difference

in sample A and B compared to C, D and E; this is due to the same loop length

maintained during knitting. Small increase in thickness is observed with the increase

in the silk proportion. This may be due to increased hairiness and slubs in silk yarn.

The loop shape factor value, which is more than 1.3 for all the fabrics indicate that the

fabrics are in stable condition. Though there is small increase in tightness factor with

the increased proportion of silk is observed, there is no significant difference between

the tightness factors among all five fabrics.

Pilling Rating 2 3 3 3.5 3.5

100% Bamboo fabric has lowest bursting strength and 100% Silk has the

highest amongst all. The bursting strength increases with the increase in silk

proportion. The reason is mainly due to the higher strength of silk fibres. 50% Bamboo

and 50% Silk yarn showed lower tensile strength but fabric bursting strength of 50/50

blend ratio is higher than 100% bamboo and 75% bamboo/ 25% silk fabrics. This can

be explained as the bursting strength is not only dependent on tensile strength of yarn

but also is influenced by other factors like fabric structure and fibre strength.

Abrasion resistance is one of the whole complex variables involved in the wear

life of a fabric and is influenced by many factors. With various literatures published, it

is evident that bamboo fabrics possess high abrasion resistance.

The results shown indicate that the resistance to abrasion of 100% bamboo

fabric is eight to ten times that of 100% silk fabric. Resistance to abrasion increases

with the increase in the proportion of bamboo fibres in the blend. In 100% silk and

25% bamboo/ 75% silk the weight loss is high at 10000 revolutions, compared with

100% bamboo, 75% bamboo/ 25% silk and 50% bamboo/ 50% silk, indicating that

there is decrease in abrasion resistance as the number of revolutions increase. This

may be attributed to moderate resistance to abrasion of silk fibres as reviewed in the

literature.

Shrinkage results clearly indicate that the 100% Silk fabric is more

dimensionally stable compared with 100% Bamboo fabric which has high shrinkage in

both width and length direction. This is attributed to higher moisture absorption and

swelling of bamboo fibres. Elongation percentage of 100% bamboo yarn is almost the

double than that of 100% silk yarn.

The tendency of pill formation is very high in 100% Bamboo fabric and decreases

with the increase in silk fibre proportion in the blend. Pilling is generally considered as

a characteristic of any man-made fibres. Abrasion from normal wear and cleaning

KSSRDI 2012-13

Annual Report

causes the fibres to unravel and the loose ends ball up on the fabric resulting in pills.

100% silk fabric has high resistance to pilling.

C. Moisture Relational Properties:

Wicking in Length(mm) 43 40 37 20 9

The moisture regains and wicking test results are given in Table 5.1. The

Moisture regain noted to be higher in 100% bamboo fabric and decreases with the

increase in proportion of silk. 100% silk fabric has the lowest moisture regain. This is

due to higher moisture regain of bamboo fibres.

100% bamboo fabric has higher longitudinal wicking in width as well as in

length followed by 75% bamboo/ 25% silk, 50% bamboo/ 50% silk and 25% bamboo/

75% silk. 100% silk fabric has the least wicking in both width and length. This is

apparent at both the test time of 5 minutes and 30 minutes. This is mainly because the

man-made fibres are uniform in nature, which enhances the capillary rise of the

material.

From the above Table-6.1, it is clear that 100% bamboo and 75% bamboo/ 25%

silk fabric possesses better fabric handle properties, which is a measure of feel of the

fabric than 50% bamboo/ 50% silk, 25% bamboo/ 75% silk fabric and 100% silk.

100% bamboo and 75% bamboo/ 25% silk fabric has higher drapability than 25%

KSSRDI 2012-13

Annual Report

bamboo/ 75% silk and 100% silk fabrics. 50% bamboo/ 50% silk fabric possess in-

between drape co-efficient.

Bamboo fibres have inherent drapability and the inherent drapability of silk is

diminished by slubs present in the yarn which increases the thickness of the silk

fabrics. Drape co-efficient decreases with the increase in the thickness of the fabric.

Hence a decreasing drape trend can be observed as the percentage of silk fibres

increase in the blend.

Colour fastness to washing, rubbing and light are important from the customer

point of view as it influences the aesthetic appeal. Fastness to washing is same for all

the fabrics and rating is considered to be good. The dry rubbing fastness results also

reveal the same. But the wet rubbing fastness is average in bamboo rich blend fabrics

(A and B). This may be due to weakening of fibre bonds in bamboo when wet which is

also reflected in lower wet strength of bamboo fibres.

The light fastness property of the bamboo rich (A and B) and 50% bamboo/50%

silk fabric is slightly higher than the silk rich fabrics (D and E). This may be because of

UV-resistant property, one of the inherent properties of bamboo fibres.

G. Microscopic Study

The bamboo and silk fibres were observed under microscope. The resultant yarns

were also observed under microscope to study the arrangement of fibres in the yarn.

The microscopic study revealed some of the facts and also supplemented the results

obtained from various tests conducted previously.

Figure-4.10 : Bamboo Fibres Figure-4.11 : Silk Fibres

Fig.4.12- 50%Bamboo/50% Silk yarn Fig.4.13: 25%Bamboo/75% Silk Yarn

Figure-4.10 shows the longitudinal view of the bamboo fibres. It is observed that the

bamboo fibres are uniform along the length. They are bright and lustrous. Longitudinal

view of silk fibres is shown in Figure-4.11. Silk fibres are finer and less uniform

compared with bamboo fibres.

Figure-4.12 and 4.13 shows the yarn samples with blend ratio 50% bamboo/50% silk

and 25% bamboo/75% silk, previously dyed using Acid dyes (Acid Black Colour).

KSSRDI 2012-13

Annual Report

Black colour was chosen as Acid dye can colour silk fibres and bamboo will not

absorb acid colours. This gives a differential colour dyeing which enables easy

identification of fibres in yarn under microscope.

From the observations it was evident that the blending was homogeneous to a

larger extent even though blending was taken up at draw frame stage. This indicates

better compatibility of the fibres in the blend, which is also supported by the tenacity

test results given in Table-3.1 which is in agreement with the studies made by W J

Hamburger on “Tensile Properties of Blended Yarns”.

It was also observed that most of the protruding fibres were black fibres, which

indicates that the hairiness in the yarn is mainly caused by silk fibres. Shorter length

and length variations of silk fibres are responsible for hairiness. Longer bamboo fibres

tend to lay straight to core of the yarn and do not protrude out.

Figure-4.14 shows the slub in the blended yarn. It is clear from the observations

that the slubs are consisting of entangled mass of fibres and majority of the fibres in

the slub are black in colour. It means that the slubs mainly consist of silk fibres. These

slubs are compressible and hence do not cause problem during knitting.

Table-5.1 and Table-5.2 show the tentative production cost of Bamboo/Silk

material. The cost of blend yarn increases with the increase in silk proportion, as the

raw silk material cost is moderately high. As same process sequence and machines are

utilized in the process, there is no significant difference in cost of production.

KSSRDI 2012-13

Annual Report

The difference observed in conversion cost is due to higher wastage of fibres and

stoppage of machine in case of roller lapping which is observed to be higher with the

increase of silk proportion in the blend. Bamboo fibres blending with silk reduce the

cost of blended yarn, with improvement in comfort and aesthetics, making it easily

affordable by rich and middle class people.

Conclusions / Recommendations

With reference to the discussions following conclusions can be drawn.

A new variety of blended yarn and fabric with Bamboo/Silk hybrid fabric is

successfully developed.

KSSRDI 2012-13

Annual Report

The settings and parameters have been established to produce the new blended

yarn in short staple spinning.

The tensile strength of yarn decreases up to 50/50 ratio and increases with the

increase in silk proportion in blend.

Elongation percentage increases in the yarn with the increase in the bamboo

proportion in blend which is one of the important yarn properties required for

knitting.

Uniformity of yarn increases with the addition of bamboo in silk.

All the varieties of yarns with different blend ratios can be commercially utilized

in knitted fabric production without any difficulty in flat bed knitting machine.

Bulkiness and thickness of the fabric increases as silk content increases.

Bursting strength of the fabric increases with the increase in silk proportion in

the blend ratio where as abrasion resistance decreases.

Pilling tendency is high in 100% bamboo fabric and decreases with increase in

silk rich fabrics because of fibre fineness.

Moisture relational properties like moisture regain and wicking results indicate

that 100% bamboo and bamboo rich fabrics give more comfort than 100% silk

and silk rich fabrics.

Test results have shown that the 50/50 blend ratio is better compared to other

blend ratios in many of the important yarn properties for knitting. Bamboo and Silk

blended material is much suitable for the applications like apparels and home textiles.
