SERICULTURE DIVISION:

Development of robust silkworm races , innovations in silkworm rearing technologies

and disease and pest control are some of the important areas that have been addressed

by the division. 23 projects were implemented during the period. In the silkworm

breeding and genetics section work on improvement of unique race KS10 was

continued and a new line KS 27 was developed with improvement in productive

characters without compromising on retaining inhibitor of diapause gene. Efforts were

made to transgress Id gene in to PM with aim of using PM males which at present are

sent for reeling. Studies were also initiated on crosses between PM and KS10 to

understand the genetics of inheritance of cocoon colour and diapause. Post

authorisation popularisation of MH1 X CSR2 were carried out in collaboration with

CSRTI and NSSO institutes of CSB. More than 1,11000 DFLs were distributed during

the period harvesting more than 64.54 kgs of cocoons per 100 dfls. Among all the

multivoltines taken up under the popularisation trial MH1 X CSR2 ranked first.

However, the reeling parameters need to be addressed by the breeder before taking up

further popularisation programme as expressed by CSB report. Maintenance of

Germplasm races is continued for the current year also. The division has identified two

new improved cross breeds viz. RP9 x NK2 and RP9 X CSR2 which need to be field

tested. Maintenance of germplasm race of both multivoltine and bivoltine was

continued.

Studies on seed technological traits of new race KS10 along with preservation schedule

was taken up and completed and included in package of practices. Similar studies

were also taken up on the bivoltine race KSD8. Field popularisation of new innovative

technology OFIT (One feed per instar technology) was taken up during the year.

Botanical based bed disinfectants Samvardhan for control of all diseases and Suraksha

Green for control of fungal disease were released. Screening of new races developed in

the Institute against Kenchu virus, Bacteria and NPV were also taken up and

completed. Under the identification of donar parents for disease tolerant races studies

were continued on challenging and directional selection of identified races for various

diseases.

The division has implemented the project on “Characterization of Pathophysiological

Factors causing Spinning Syndrome in Silkworm Bombyx mori L.” funded by

Department of Science and Technology. Pebrine disease survey and surveillance was

carried out in Pure Mysore Seed Area. Thorough mother moth testing was adopted to

screen the lots. Studies were also taken up on a new Microsporidian prevalent in the

seed area. Through experiments it was concluded that the new Microsporidian though

different from regular Nosema Sp. is virulent and it was recommended that, lots

infected with this microsporidia should also be rejected.

A new mountage viz.,Thalaghattapura Ribbon Chandrike was developed and released

during the period under report. Popularization trials are to be taken up. The new

mountage is user friendly, cost effective and facilitates self mounting and mechanical

KSSRDI 2014-15


harvesting. It was found that the quality of cocoons harvested out of these mountages

is superior with less number of defective cocoons.

Four books were published during the period in which the scientists contributed.

Modules for E-learning were prepared by the scientists. They participated in various

training programmes, Doordarshan programme and AIR as resource persons.

SILK TECHNOLOGY DIVISION: Silk Technology Division is having two sections with two Scientists – E, three Scientists – D and four Scientist-- C and one Scientist - B. The major thrust areas are silk reeling and weaving and silk processing. Totally nine projects were executed in the division during the reporting period, including four completed projects.

Silk Reeling and Fabric Manufacturing Section : The project titled “Technology of reeling urine stained cocoon” has been completed and completion report is being presented. The urinated cocoons during rainy season pose great difficulty in terms of reduced reelability, increased waste % and resulting in inferior quality of raw silk. The analysis of urine stained cocoons and process performance have been carried out. Corrective measures using acetic acid, critic acid in different concentrations have been tried. Addition of 0.3% of resin to cooking both has shown promising results. The field trials will be taken up. The project titled “Evalaution of yarn imperfections due to inferior cocoons at reeling” has been completed and completion report is being presented. Cocoon lots contain different proportions of defective cocoons during different seasons. Cocoon lots were analysed for different seasons and defective cocoon % were estimated. The effect of these on reeling performance and quality of raw silk has been documented. The project titled “Studies on different methods of soaking” has been completed and completion report is being presented. Different methods of soaking practiced in the industry along with vacuum method of soaking have been compared. The effect on these methods by varying chemicals, duration has been recorded. The use of vacuum conditions have shown better results in terms of better yarn properties compared to open bath method. Under the “Catalytic Development programme” training were imparted to 480 reelers from seven reeling clusters. The training module included the creation of awareness about new technologies and methods developed by the Institute. The project titled “Design and development of Electronic reeling machine (ERM)”, the experiments have been concluded to ascertain power consumption with drive namely as reel shaft drive, traverse mechanism and jettebout drive.

Silk Processing Section: Under the project titled “Unconventional method of degumming of silk yarn and popularizing of technology in the field level” The results emerged out of experiments were demonstrated with few processing units. The utilization of sericin application and analysis of fabric properties were carried out. Under the project titled “Indigenous silk fabric produced from excess PM seed cocoons” A field survey was conducted at Prodattur, AP regarding the utilization of PM raw silk yarns. A new project proposal titled “Silk noil yarn utilization for Navalgund and Warangal, Dhurries development for floor fashion” has been prepared and submitted to Central Silk Board for funding.

M-I-2(ii): Studies on status of available boron in the mulberry garden soils of Malavalli

taluk of Mandya district Duration : 3 yrs - 2012-15

Project Leader : Dr. H. Thimmareddy, S-D Project Investigator : Smt. Savitri P Magadi, S-C

a) Objectives:

a. To know the available boron status of mulberry garden soils of Malavalli taluk, Mandya district.

b. To find out the soil parameters influencing the available boron content in the soil.

b) Results: Totally 189 soil samples were analyzed. The soil analysis data revealed that the soil pH was normal (6.2-7.3) in 19 % (35), moderately high (7.3-8.3) in 73 % (138) and high (>8.3) in 8% (16) soils. Organic carbon content was low (0.5%) in 41% (78), 57 % soils are (107) in the medium (0.5-1.0%) and 2 % soils in high (>8.3) range. Available P was low (<22 P2O5 kg/ha) in 49 % (93), medium (22-55kg/ha) in 37 % (69) and high (>8.3) in 14% (27) of the soils. Available K was low (<125 kg K2O/ha) in 23% (43), medium (125-312 K2O kg/ha) in 54 % (103), and high (>312 K2O kg/ha) in 23 % (43) of the soils. Available boron was low (<0.5 ppm) in 55 % (104), 36 % (68) soils are in medium (0.5-1.0 ppm) and 8 % (16) soils are in high (>1.0 ppm) category. Available S was deficient (<10 ppm) in 55 % (104) and sufficient (.10 ppm) in 45 % (85) soils. The available Zn was deficient (<2.0 ppm) in 75 % and sufficient (.2.0 ppm) in 25 %, available Fe was deficient (<2.5 ppm) in 42 % & sufficient (>2.5 ppm) in 58%. The soils are sufficient with respect to available Mn and Cu (Table 1). The correlation analysis between soil parameters revealed that the available B has

negative significant correlation with soil pH (-0.476*), electrical conductivity has negative significant correlation with available Zn (-0.413*) and available Cu (-0.401*). Organic carbon has significant positive significant correlation with exch.Ca (0.509**), exch. Mg (0.416*) and with available boron (0.548**). The Exch. Mg has positive significant correlation with available Fe (0.463*). Available Zn has positive significant correlation with Cu (0.395*), available Cu has positive significant correlation with Mn (0.441**), and available Fe has negative significant correlation with Cu (-0.396**) (Table 2).

KSSRDI 2014-15


c) Recommendations /Conclusions: The available boron content in the soil has positive significant relation with organic carbon, negative significant correlation with pH. Therefore, maintenance of optimum level of organic carbon content in the soil through application of optimum quantities of organic manures is recommended. Use of S containing fertilizers is suggested to reduce the pH.

Experiment 1: Isolation of potash mobilizing bacteria (KMB) from mulberry rhizosphere soils and evaluation of its efficiency. Results The isolated bacteria exhibited clear zones and were maintained on nutrient agar slants. The bacteria were gram negative bacilli, rod shaped and motile. Out of the four isolates KMB5 was found to be good in solubilizing potash. Experiment 2: Evaluation of the effect of potash mobilizing bacteria on mulberry.

Results: Significant improvement in plant height, leaf yield and root volume were recorded in presence of KMB isolate compared to control. Growth and biomass was found to be higher when compared with plants treated with Frateuria aurentia (obtained from Regional centre for Organic farming, Bangalore). Leaf yield (78g) and root growth (73.20ml) was maximum in presence of 75% K+ KMB. Inoculated plants performed better even in presence of reduced dose (75%) indicating that Potash mobilizing bacteria also has a solubilizing trait.

Experiment - 3: To study the response of mulberry to co-inoculation with potash mobilizing, phosphate solubilizing, nitrogen fixing bacterial isolates and VAM. Results: The present research findings provide information that sustained growth and leaf yield can be achieved with 75% of NPK fertilizers with combined inoculation of all the beneficial microorganisms. Thus the application of reduced chemical fertilizers with consortium of all microorganisms can be recommended for mulberry to increase the yield and to maintain soil health in the ecosystem.

Experiment - 5: To study the effect of pH on potash solubilization Results: It was found that K solubilization was maximum when bacterial strains were grown in cultures with pH 6.5 and 7.0. with increase in pH of the medium K solubilization decreased. Maximum K solubilization was observed at pH 7.0 and was minimum at alkaline pH. Experiment- 6: Solubilization of Muriate of Potash at different dosages in incubated soils with Potash mobilizing bacterial isolate Result: The maximum potash content was observed in soil samples of 40th day and then it declined. Experiment-7: To study the effect of KMB isolate on mulberry under field condition Result: The efficiency of the organism was evaluated in sericulturist‟s gardens. Growth and leaf yield was higher in plots treated with KMB isolate when compared with control.

Results: Isolation of antagonists : Five fungi and three bacteria were isolated from the rhizosphere of mulberry. They were isolated on to pure culture media and identified and given an isolate number. Of the fungal isolates 03 belonged to Trichoderma viride and 02 belonged to T. harzianum. Two bacterial isolates were identified as Pseudomonas fluorescens and one Bacillus subtilis (Table-1). These were maintained on PDA and NA media for further use On farm trials of selected isolates in sericulturists gardens: The two Trichoderma isolates viz., T. viride (MPM-1), and T. viride (MPM-14) which showed maximum disease control in field experiments at the institute campus were selected for an on farm trial in 08 selected sericulturists mulberry gardens in Kanakapura taluk of Ramanagara district, with heavy infestation by root rot disease. The inoculum was applied at 2 kg/acre/year in two splits multiplied in 25 kg neem cake with 25% moisture. Two gardens without treatment served as control. The mortality of plants due to disease in

selected gardens before imposing the treatments ranged from 50-500. The disease incidence after 03, 06 and 12 months after application of inoculants showed maximum reduction with both the isolates used. One year after the application of the inoculants (02 doses), the disease incidence completely stopped with both the isolates used while in the control gardens the incidence increased up to 42 and 51 percent. Creation of awareness among the sericulturists on integrated root rot disease management: With a view to create awareness among the farmers regarding the fast spreading nature of the root rot disease and the damage caused, awareness

SERICULTURE DIVISION: Silkworm Breeding & Genetics Section: S.I.5.1 Project Title: Popularisation of Authorized Silkworm Hybrids among

Farmers of South India. KSSRDI component: Post Authorization Trails (PAT) of MH1XCSR2 Hybrid.

Project Leader : Dr. G.S Rajanna, S-D

Funding Agency : Central Silk Board, Govt of India, Bangalore. Collaborating : (i) KSSRDI, Bangalore, Institutions (ii) NSSO, Bangalore

(iii) Dept. of Sericulture, Karnataka,.

(iv) CSR & TI, Mysore (Nodal agency) Year of Initiation : Nov, 2012

Objectives : (i) Large scale field Popularization of Authorized Improved Cross Breed MH1XCSR2 (ii) Evaluation of the new hybrid for pre-cocoon and post-cocoon parameters and field

conditions.

Recommendation by Central Silk Board, Bengaluru on ICB MH1 X CSR2 (PAT Project concluded in Oct‟2014):

A total of 1,13,650 Dfls of MH1 X CSR2 were distributed in Summer, Rainy and winter seasons to the farmers of Karnataka

The average cocoon yield per 100Dfls was 61.52kg as against 61.00kg in PM X CSR2(control)(Table:4& 5)

The average Price per kg of cocoons was Rs.337/- as against Rs.300/- jn control hybrid PM X CSR2.

The ICB MH1 X CSR2 recorded silk quality of “B” to “2A” grade (Table-S1.9ABC) The MH1 X CSR2 hybrid performed better than PM X CSR2 hybrid. Hence,

MH1 X CSR2 hybrid serves as alternate resource to the existing hybrid and can be exploited commercially.

DoS, Karnataka expressed their misgiving about the hybrid with regard to reeling performance

However, in response to enquiry regarding reeling performance from KSSRDI, The Director, CSTRI, CSB Complex, Bengaluru ( letter No.CSB/CSTRI/MSRD/PAT/2015-16, dated:21.7.2015) has opined as follows: “ MH1 X CSR2 hybrid cocoons can be reeled effectively by using CSTRI Multi-end reeling technology package and good raw silk recovery and international grade raw silk of A to 2A can be produced depending on the cocoon quality. Minor modifications in the adoption of reeling process parameters depending on the cocoon quality, season of rearing etc., have been propagated among the reelers and they will be able to adapt the same according to the requirement”.

Duration : 3 years Project Leader : Dr. N.R.Prasad–SD

Objective:

To determine the degree of tolerance of new silkworm races developed in KSSRDI to

Kenchu virus, fungus (white muscardine), BmNPV and mixed bacteria in comparison

with commercially important race.

Sub project- 1

Title: Screening of new silkworm races against Kenchu virus and fungal diseases.

Sub- Project leader : P. Sharadamma, S-C

Project duration : 3 years

Project Initiation : 2012-13

Funding : Internal funding

OBJECTIVES:

To determine the degree of tolerance of new silkworm races developed in KSSRDI to Kenchu viral disease (DNV) of silkworm, in comparison with commercially important race. RESULS AND DISCUSSIONS:

LC-50 for mortality:

Among the bivoltine pure races, based on LC50 values, it is noticed that as compared

to control race CSR2, BRO2 and HND were found to be more resistant during summer

and rainy seasons followed by NK2 and NP4 and KS10, while in winter season CSR2

was more resistant followed by BRO2 , KS10 NK2,HND and NP4. Among the bivoltine

hybrids, during summer, control race CSR2xCSR4 was highly resistant followed by

BRO2xNP4, KS10xBRO2, BRO2xNK2 and KS10xCSR2 and during rainy and summer

seasons, BRO2xNP4,and BRO2xNK2 were more resistant followed by the control race

CSR2xCSR4.Among the crossbreeds, PMx NK2 showed more tolerance to DNV disease,

during Summer and winter seasons followed by RP9xNK2 and control race PM x CSR2,

while RP9xNK2 was more tolerant than PMx NK2 during rainy seasons.Among the

polyvoltines, MH 1 was found to be highly tolerant to DNV disease during all seasons

followed by SLKSPM and RP9 (Table-2)

The study indicates that there is a Seasonal variation in the resistance/ susceptibility

among the the new races viz.,BV pure, BV hybrids, Cross breeds,and polyvoltines

KSSRDI 2014-15


and even among the most resistant /susceptible races least mortality % is noticed

during Winter as compared to rainy and summer seasons which confirms that DNV

disease is predominantly seen during summer and rainy seasons. Among the races

screened the cumulative mortality % for all the races decreases with the increase in

virus dilution during all seasons. (Table-3&4)

OUTCOME:

Silkworm races as bivoltine pure and bivoltine hybrids , multivoltine pure and

multivoltine hybrids which were promising in the breeders work were screened against

the kenchu virus. It was found polyvoltine pure and hybrids were more sucesseptible to

kenchu than bivoltine and their hybrids. Among pure BV races BRO2 found more

resistant to kenchu both in summer and rainy followed by HND and NK2 , where as

CSR2 found better in winter. Among the BV hybrids BRO2 and NP4 scored better in

their resistance to kenchu during rainy and winter where as CSR2 scored well during

summer. Among all polyvoltine pure and hybrids MH1 pure and its hybrid performed

better than the rest. Season variation among the races against disease could be utilised

in breeding programme.

Sub project 2 :

Title : Screening of new silkworm races against Nuclear Polyhedrosis Virus

Name of the PI : Dr. N.B. Jyothi, S-C

Source of funds : Internal funding

Year of initiation : 2012 Dec

Duration : 2 years

Objective: To screen the identified silkworm races against BmNPV and record the

tolerance level.

RESULTS

Polyvoltine races are significantly tolerant to BmNPV compared to Bivoltines.

Among bivoltine pure races degree of tolerance varies

(NP4>HND>BRO2>KS10>NK2>CSR2).

Among polyvoltine pure races the tolerance level is as indicated

(MH1>PM>RP9>RP4).

The tolerance level in cross breed races is high compared to the pure races and

depends on the tolerance level of the pure female race (Table 5 and 6).

KSSRDI 2014-15


Outcome:

The results are used by the breeder in their breeding program.

Sub project.3 S.V.5.6.3

Title: Screening of new silkworm races against Bacterial flacherie (Mixed

bacteria)

Sub Project Investigator : Dr. N.R. Prasad , S-D

Objectives:

To determine the degree of tolerance of new silkworm races developed in KSSRDI to

flacherie disease in comparison with commercially important races.

Results and discussion:

The LC 50 values of representative races for BV pure, BV hybrids , MV Pure and their

hybrids varies with the dose and season. This shows the evolved and pure races show

variability in disease tolerance towards bacterial infection. Generally in winter,

mortality was observed when high load (low dilution value) of pathogen was given

comparatively in all the races. Where in, during summer, mortality was high in the low

doses (high dilution values) of pathogen. All the MV or poly voltine hybrids and pure

races were comparatively more resistant to bacterial infection when compared with BV

and their hybrids. The LC50 value for 50 % mortality ranged from 1.02x103 dilution to

3.30x105 pathogens per ml. BV races showed susceptibility even at low doses of

bacteria i.e., high dilution values. Among the combination of races CSR2 and CSR4

combinations showed highly susceptible compared to other races and HND , NK2 and

MH1 combinations showed higher tolerance . The values of LC50 can be directly

interpreted as higher the LC50 values more tolerant the races. The order of resistance

to the infection was NK2 x HND > PMxNK2 > PMxCSR2 > MH1 > NK2 > CSR2xCSR4.

(For details see Tables 7 to 11 and corresponding table showing statistical analysis)

Outcome:

The study throw light on racial difference in the tolerance level to bacterial infection

seasonal variation in tolerance. The LC50 values for each race with respect to season

(winter, summer and rainy ) directly give clue the season at which the race show more

survival. The result are most useful for breeder to select write parent for breeding

experiment to evolve disease resistance race, seasonal race.

Mountages play vital role in determining quality of cocoons. Spinning activity begins at

the end of 5th instar demanding immediate attention and labour force for activities such

as picking the ripe larvae, arranging mountages and mounting of spinning larvae,

removal of non-spinning and dead larvae, harvesting of cocoons, cleaning of cocoons

and packing of cocoons for marketing. Several types of cocoon mountages are being

used in different geographical regions viz., Bamboo mountage (Chandrike), Plastic

corrugated mountages, Rotary mountage, Sudharshan chakra, Paddy straw mountages

etc.,. Attempts have been made to simplify the activities during spinning to reduce the

labour force and labour cost through self-mounting and mechanized harvesting

systems. However, these technologies have not been fully user-friendly due to

inappropriate and laborious activities during self-mounting and mechanized

harvesting. The sudden surge in demand and dependency on labour force to comply

spinning activity has been a serious concern to the farmers and industry. The

dwindling labour resource and ever increasing input cost and labour cost in recent

times has posed challenge to the growth and sustainability of industry. In addition, the

cost of mountages currently used is high. With this background, Karnataka State

sericulture Research & Development Institute has developed a new user-friendly

cocoon mountage „THALAGHATTAPURA RIBBON CHANDRIKE‟ (TRC) which reduces

labour cost and dependency with low capital investment suitable for self-mounting with

mechanized harvesting technique

ADVANTAGES OF THALAGHATTAPURA RIBBON CHANDRIKE:

Drastic reduction on labour cost and quantum of work:

Thalaghattapura Ribbon Chandrike is suitable for self-mounting of matured

larvae hence, work related to picking of individual spinning larvae and

mounting them on to mountages is avoided. Therefore the work load , labour

force, labour cost is reduced in management of spinning larvae

Mechanized harvesting of cocoons is achieved by simple act of drawing the

ribbon through the „harvest slot‟ created in the bucket/container, the entire

cocoons in the mountage is harvested in less than a minute. It takes 10

minutes to harvest 100Thalaghattapura ribbon mountage as against 20

hours in Bamboo mountages as a consequence the labourforce andcost

oflabour leading tosignificant increment in the profit margin to the farmer.

Investment cost on mountages:Thalaghattapura Ribbon Chandrike is

fabricated with locally available materials such as wooden strips, MS screws

and plastic ribbon which are less expensive

Thalaghattapura Ribbon Chandrike does not require any additional gadgets

such as templates (as in case of Rotary mountages) or machines for

harvesting of cocoons leading to total avoidance of investment on gadget

leading to saving on the investment cost

Thalaghattapura Ribbon Chandrike do not demand high-tech fabrication

techniques, it can be easily fabricated by the local artisans or farmer himself.

Hence, it avoids renting mountages which is expensive and widely practiced

by farmers.

The design of the new mountage provides congenial conditions such as

uniform spacing in the mounting frame, ample ventilation and easy

separation of urine and feacal matter that is evacuated from spinning larvae

leading to for production of uniform good quality cocoons

The material and design of new mountage enables easy disinfection

The storage of new mountage is easy and demand less space

The concept of new mountage opens up new avenues in designs/techniques

and refinements to achieve further simplification and cost reduction

SILK TECHNOLOGY DIVISION: SILK REELING AND FABRIC MANUFACTURING SECTION: 1. Project Title : “Technology for reeling urine stained cocoon” Project Investigator : A. G. Shankar, S-E Co-PI : M Nagesh, S-C Project Assistant : R Rajanna, S-B

Duration : Two years Introduction:

Due to high humidity in the atmosphere during monsoon, matured silk worms, excrete body liquid in the form of urine on the mountage. This liquid fall on the cocoon surface of other worms and stains them. The urine stains on the cocoon make the cocoons defective as it is not possible to reel them as normal cocoons, leading to high silk wastage, low yield, and poor quality yarn. Due to this, reelers offer less price for the cocoon lots which contain more urine stained cocoons. Field scenario: In a survey conducted, it is recorded that the cocoons lot contained about 17.6% of stained cocoons during rainy season and 4.5% during winter seasons. The reelability of urine stained cocoons is low as the chemicals from the urine dissolve in the cooking and reeling bath which affects the processing of cocoons resulting in high filament breakages leading to low reelability. Due to frequent brushing of the cocoons, silk waste extracted and cocoon wastage is high due to excessive boiling, water turbidity and pelade layer wastage of cocoon increase. Due to poor reeling performance of such cocoons the renditta increases and quality of raw silk decreases. Hence it was found necessary to evolve effective method for reeling urine stained cocoons, which is beneficial for the industry. Objectives: 1. Study the effect of silk worm urine on the filaments of the cocoon shell 2. To develop effective method for reeling of urine stained cocoons.

The mature silkworms after building the hammocks on the mountages, and before beginning to spin cocoon, excreted body fluid was collected in a filler tube and stored in test tubes. Five samples of silkworm urine was collected and given for chemical analysis at GKVK laboratory. The results are as below.

It can be seen that the pH of the solution is high varying between 8.56 to9.68, which could be inferred that the solution render the reeling water alkaline, which results in higher wastage and in turn affect yield. Iron and manganese is also high, these being trivalent elements can cause more harm than calcium and magnesium in reeling water. Work element II : Study of the physical characteristics of urine stained filament. Filaments from stained cocoon were studied in raw and softened state, to know the extent of damage caused to the filament due to the stain. Silkworm urine was collected and treated on normal filament to study the effect of urine on the sericin of the filament. In order to differentiate sericin from fibroin, the filament was colored with a differential dye where only sericin was stained and fibroin remained unaffected. This technique was adopted to identify the damage caused to sericin due to silkworm urine. From the microscopic studies conducted it was observed that, when the urine droplets came in contact with the filament, sericin dissolution took place at the point of contact. When the stain dries, sericin gets separated from fibroin like flakes, exposing fibroin. At some places, it was observed that the chemicals of silk worm urine had damaged the filament at the region of contact, sericin was dissolved completely and fibroin was exposed. Region with larger and deeper stain lead to fibrillation. Loosened fibrils, caused a weak point in the filament which caused filament breakages. Sericin dissolved region also may lead to filament breakage.

vi) Filament breakage due to fibrils getting separated. vii) When droplet of silk worm urine was put on the normal coloured filament, sericin

got dissolved and moved away from filament in globule form. viii) It was observed that sericin of the stained portion can easily separated physically. It was also observed that the sericin could be easily stripped from the filament surface by physical means, exposing fibrin completely. This shows that during reeling, stained sericin is stripped off the filament when filament is pulled over machinery parts leading to breaks.

Work element III : Identification of chemicals to neutralize the effect of silk worm urine Water for processing cocoon was treated with citric acid to neutralize the chemicals in the cocoon boiling and reeling bath. Constituents of water was checked after mixing with citric acid in cold and after boil, and after boiling stained cocoons for the first, second and third time. Three concentration of citric acid (0.25%, 0.5% 1.0%). was experimented to study the effect in neutralizing the effect of silkworm urine chemicals. Definite trend was not seen reeling with the three treatments compared to control.

Cocoon wastage after partial reeling was observed this could be due to increase in acidity level in waterwith higher concentration. Statistical analysis of mean values of brushing % and silk waste % was found to be significant. For reelability % and raw silk % the difference in the means was not significant. The yarn was observed for cleanness defects and was found to contain more slubs. Treatment with acetic acid: Experiments were carried out after boiling cocoons in water treated with acetic acid with the concentration of 0.125%. 0.25% and 0.5%. Treatment of cocoon with acetic acid has reduced the reeling performance of the cocoons. This is due to the increase in acidity in the cocoon boiling water. During experiments it was observed that the cocoon wastage was high. The treatment was abandoned as the treatment had reduced reeling performance even at very low concentrations. Treatment with resin: PVA resin treatment was given for binding the filaments and to cover the fibroin exposed portion such that the bave did not yield to the strain at these points during reeling stage. The concentration of resins was 0.2%, 0.3%, 0.5% and 0.8%. Table III.1: Study of treatment with resin.

Project Investigator : H. R. Parashivamurthy, SC. Co-Investigator : A.G. Shankar, SE. INTRODUCTION: Generally cocoons are classified as reelable cocoons and defective cocoons. Defective cocoons are integral part of cocoon harvest and they are formed in a rearing process

due to various reasons. During reeling, defective cocoons affect reelablity, reeling efficiency, quantity and quality of raw silk yarn. The quantity of defective cocoon varies from 5 to 20 % depending on rearing & spinning conditions and varies from season to season. Before reeling, cocoons are spread on the floor and only double and flimsy cocoons are separated, where as other type of defective cocoons are reeled along with good cocoons without further sorting. When reeling is carried without separating defective cocoons the reeling process and quality of silk is affected. The present study is to understand the different types of defective cocoon percentage present in commercial cross bread lots, in different seasons and its effect on reeling and the yarn quality. The outcome of the study helps to understand the extent of yarn imperfection arising by the defective cocoons so that a cocoon sorting plan could be established. OBJECTIVES:-

1. To conduct survey to assess the quality of various defective cocoons in the Commercial lot Crossbreed cocoons (PM x CSR2) at Govt. Cocoon market.

2. To study the imperfections in yarn due to various inferior cocoons. Methodology: 1. Conducting the survey to assess the quality of defective cocoons present in the

Commercial lots of Crossbreed cocoons (PM x CSR2) at Govt. Cocoon market in all the three seasons and compilation of survey data.

2. Procuring of commercial crossbreed cocoons and assessing cocoon characteristics.

3. Separating defective cocoons and processing cocoons normally viz hot air dried,

conditioning, reeling and re-reeling.

4. Reeling good cocoons with mixture of inferior cocoons in various proportions viz 95:5, 90: 10, 85:15 and 80:20 in cottage basin. Collecting the reeling data and raw silk quality.

5. Compilation of reeling and raw silk quality.

A. Survey of defective cocoons in commercial lots:

Survey was conducted during monsoon, winter & summer season at GCM, Ramanagara to assess the quantity of defective cocoons in the commercial lots. One kilogram cocoon were randomly selected from each lot and various defective cocoons were separated from good cocoons. Weight of all types of defective cocoon was recorded. Tests were conducted for 115 lots during monsoon, 120 lots during winter & 161 in summer. The defective cocoon percentage present in each lot was assessed. The data collected was statistically analyzed. Defective cocoon of 115 lots during monsoon is depicted in table- 1 Table. 1. Defective cocoon assessment for Monsoon season.

Observation: • The range of defective cocoon % varied from 16.67 to 24.33 %. • Overall defective cocoon percentage in the lot is 20.97. • Urine stained cocoons were high (13.67 %) when compared to other types of

defective cocoons.

The statistical analysis results are shown in the table 8, 9 &10. Fig-3. Shows raw silk % with different proportion of DC.

Fig-4. shows the silk waste & with different proportion of DC.

DC% It is seen that there is significant difference in reelability, among the batches of different proposition of defective cocoons. Further, it can be observed that as the defective cocoons percentage increases the reelability decreases and for increase of 15 % of defective cocoons, the reelability has dropped by 15 %. To understand the relationship better correlation coefficient was determined. Table 8 and fig.5 shows good correlation between these two factors. Similarly the raw silk % obtained for these batches, ANOVA and correlation coefficient have been shown in Fig.6. For raw silk percentage also there is significant difference among the different defective cocoons percentage. In addition correlation coefficient being -0.75, the relationship between characteristics is observed to be good. The details of silk waste percentage and the statistical result are shown in the Fig.7. It can be observed that the silk waste percentage has increased with the increase in defective cocoons percentage. For the quality characteristics the statistical analysis was made. It is observed from the table that only cleanness percentage has shown significant difference with respect to various defective cocoons percentage. The details of cleanness percentage ANOVA and correlation coefficient are shown Fig. 8. It is observed that good correlation exits between cleanness percentage and defective cocoons percentage.

Conclusion:

From the study, it is observed that the defective cocoon content in cocoon lots is highest during monsoon. In this season urine stained cocoons are highest. These types of defective cocoons are also observed to be more in winter season.

The quantity of melted cocoons is higher in all season and is maximum during summer. Malformed and thin shell cocoon occurrence is also high during summer. Reeling experiments conducted by mixing defective cocoon with normal cocoons has revealed that, as the defective cocoon percentage increase, raw silk yield and yarn quantity will decrease. In addition, the raw silk quality is also lowered due to decrease in cleanness percentage. From the study it can be concluded that, i) Silk worm rearing practices to be improved with mounting management to avoid

urine stained cocoon occurrence during monsoon and winter. ii) Proper Rearing conditions are to be followed as per recommendations to avoid melted

and Uzi pierced cocoons. iii) Defective cocoons have to be separated in order to increase yarn yield and improve

yarn quality.

2. Project Title: Studies on different methods of soaking.

Project Investigator : S. Honnappa Co-investigator : A. Jambunath Project duration : 1 year

Introduction: Silk manufacturing process involves introduction of twist to single and plied raw silk yarn. Raw silk yarn is converted into hanks after drying at re-reeling. The presence of sericin renders the raw silk yarn hard, stiff and brittle offering resistance to twist. The amount of twist imparted to raw silk yarn differs depending on the type of fabrics being manufactured the twist inserted is in the range of 400to 800 Tpm in soft silk variety and 2200-4000 Tpm in high twist fabrics . The high twist fabric like Chiffons and

Georgettes requires both warp and weft with higher level of twist and in Crepe fabrics only the weft is highly twisted. The silk filaments are very fine and have high torsional rigidity, the presence of sericin offers resistance to twisting. Raw silk yarn is soaked to increase the pliability and decrease the torsional rigidity before twisting the yarn. Soaking is a process of softening the sericin using a solution of oil and soap before twisting operation to overcome the inadequacies faced by the material in twisting. Objectives:

To compare the different methods of soaking silk yarn.

To evolve soaking method by vacuum. Methodology:

Procurement of raw silk yarn.

Soaking of raw silk with commonly used recipes.

To evolve best soaking method with process standardization.

I. Experimentation: Raw silk produced on cottage basin was procured and its properties were evaluated and considered for the study. Raw silk was treated with 1)2% soap and 4% coconut oil. 2) 4% Mrudula soaking oil. 3) 2% Non ionic surfactant and 4% coconut oil. The three recipes for soaking was carried out separately in open bath for a period of

5 hrs with material to liquor ratio of 1:5 at 40°C temperature and in vacuum soaking method the same recipes were used under vacuum condition at 400mm of Hg for a period of 30 minutes. The duration and pressure of vacuum was worked out taking trials. The treated silk was compared for yarn properties such as Tenacity, Elongation, and Twist to break.

Table1 and 2 depicts the yarn characteristics, process performance of yarn treated with soaking agents in open bath and vacuum condition. It is observed that the tenacity of treated silk with all the recipes in open bath and vacuum condition has an effect on the tenacity of the yarn due to softening of sericin and elongation has significantly improved facilitating better pliability of the yarn. Further, it is observed that twist to break in the yarn is better for yarns treated under vacuum condition as compared to open bath method. It is also observed that the process performance of the yarn treated in vacuum condition using mrudula oil is superior compared to other treatments. Table 3: Add on percentage

The yarns treated in open bath using soap and oil and mrudula oil open bath were compared. It is observed that the tenacity of mrudula treated samples is higher with low elongation values as compared to soap and oil open bath. The increase in tenacity values is significant at 5% level. Further the elongation values observed with soap and oil treatment is also significant at both 1% and 5% level. This is attributed to better softness of silk due to longer duration of soaking in alkaline media. Table5: Comparison of yarns treated in Vacuum condition.

The samples treated with soap and oil, mrudula and Surfactant with oil under Vacuum conditions are compared. It is observed that the tenacity values and elongation values of mrudula treated Yarn is found to be better as compared to soap and oil treatment, as well as surfactant with oil treatment. Inference 1. Tenacity of treated silk has reduced due to softening of sericin. 2. Tenacity of vacuum soaked silk is higher compared to open bath soaked silk. 3. Elongation of treated silk has significantly improved over the control sample. 4. It is observed that vacuum soaked silk with Mrudula oil has taken higher Twist as compared to other treatments. 5. Vacuum soaking has improved the process performance of yarn at winding and has no breakages observed for yarns treated with mrudula soaking oil. 6. The yarn treated sample with Mrudula oil in vacuum condition has resulted in yarns having better properties compared to other treatments 7. It is inferred that vacuum soaking facilitates better soaking of yarn under vacuum condition as compared to open bath method. Conclusion: From the above study it is concluded that, 1. Soaking of raw silk under vacuum conditions facilitates better impregnation of

soaking solution making the raw silk soft and supple with better yarn properties, as

compared to open bath method

2. Soaking in vacuum conditions saves time with less handling of materials facilitating better performance at winding.

3. Twist to break is better for yarns treated in vacuum condition indicating better

pliability of yarns.

Recommendation: It is recommended to adapt vacuum soaking method in place of open bath to facilitate better soaking of yarn retaining the inherent properties of silk. 4. Project Title : SILK REELING ENTREPRENEUR TRAINING.

Project team : Scientists of Silk reeling and Fabric manufacturing Section Duration : 1year (2014-15) Budget : Rs.17.5 lakhs

Background: As per the CDP guidelines, KSSRDI was given the task of conducting training

programme for sericulturists and silk reelers in the Institute under the Central Silk Board sponsored Catalytic Development Program. During 2013-14, only three of the 12 silk reeling training programmes were conducted in the Institute due to poor participation of reeling entrepreneurs as they were not able to attended week long program. Hence it was suggested that KSSRDI would conduct the program in the reeling cluster itself, rather than in the Institute premises, so that reeling entrepreneurs could undergo training and also attend to their routine works of their business. This proposal was accepted and training during 2014-15 was conducted in the reeling clusters. Work elements: 1. Organising training program Prior to the scheduled program the team members

visited the cluster and held discussion with the local TSC officers and reeling entrepreneurs about the training. Training venue was identified and the requirements such as, seating for 100 participants, audio, catering, etc. were made locally.

2. Publicity: The program dates were publicized in the Govt. Cocoon Markets and also personally by TSC(R ) officers.

3. Training Material: Books pertaining to silk reeling technology Do‟s and Don‟ts , Raw silk quality and water management were provided to the training participants

4. Training module : The topics covered under the program were, a. Inauguration and Introduction to the program. b. Lacunae in present reeling methods. c. Introduction to KSSRDI‟s silk reeling packages for cottage basin. d. Requirement of silk weavers. e. Partial hot air drying of cocoons, conditioning, sorting and benefits derived. f. Vacuum cocoon boiling and its advantages. g. Steel buttons, appropriate Croissure length, reeling and re-reeling speed for

improving yarn quality. h. Importance of water quality in silk reeling. i. Methods for reducing manufacturing cost and increase profits. j. Benefits provided by Dept. of Sericulture. k. Technical discussion.

Opinion of reelers during training 1. To provide subsidy for purchasing hot air dryer and vacuum cocoon boiling

equipment. 2. Steel buttons to be made available at the earliest. 3. Requirement of water treatment plants. 4. Methods to reduce cost of drying silk skeins at re-reeling. 5. Many reelers are not getting benefits provided by Dept. 6. To provide steam boilers and electrical generators. 7. Reelers find it difficult to invest 100% in purchase of equipment, hence, if

subsidy amount is released before purchase, reelers share will be paid and equipment obtained.

8. Requirement of technologies for reduction of labor. 9. Necessity for improving quality of reeling cocoons. 10. Required suitable technology for reeling urine stained cocoons. 11. Requirement of water treatment plant. 12. Requirement of cost reduction techniques at re-reeling. 13. Demonstration of the technology being recommended in the cluster. 14. Requirement of 200 ends automatic reeling machines.

Conclusion: Reeling entrepreneurs indicated the programs to be conducted regularly as it would be useful for updating their technical knowledge and interact with experts.
