MULBERRY SILK REELING

 

Ongoing Research Projects

1. Title:

Studies on improving the cohesion characteristics of multibivoltine raw silk / tasar silk / muga silk using sericin in reeling process 

Scientists involved: 

Subhas V. Naik, M. A, Joseph, S. A. Hippargi, U. C. Javali & G. Hariraj 

Projected outcome:

Study will result in production Multibivoltine raw silk, Tasar and Muga silk with significantly better cohesion characteristics so that these yarns can be effectively used as a warp in a production of different kind of fabrics.

 

2. Title: 

Studies on sericin dissolution characteristics 

Scientists involved: 

M.M. Shirol, Kariappa, Aswatha Reddy & Subhas V. Naik 

Projected outcome:

  • The correlation between sericin dissolution characteristics and reelability of cocoons will be established.
  • This study will be able to provide information to the reelers regarding appropriate cooking conditions to be adopted, while processing the cocoons during favourable and unfavorable seasons.
  • It will also help in estimating the reelability of the cocoons based on the sericin dissolution characteristics.

 

3. Title: 

A study on the price behaviour of cocoons and raw silk and its impact on the silk reeling sector 

Scientists involved: 

C.R. Nagaraj, K.N. Mahesh, S.A. Hiremath & Subhas V. Naik 

Projected outcome:

  • The outcome of the project would help in better understanding of various issues involved in the price fluctuations of cocoons and raw silk.
  • The findings would be useful in suggesting ways to the reeling units in minimising the adverse impact of these fluctuations on their operations and profitability.
  • The outcome would help in preparation of market intelligence reports for the silk reeling sector.
  • The findings of the study would also help the agencies involved in better understanding of the issues on policy related matters for the overall development of the silk reeling sector. 

4. Title:

Development of miniature eri spinning plant for better productivity and quality for adoption in North Eastern Region of India 

Scientists Involved:

Aswatha Reddy, K.M.A. Kadhar, G. Hariraj &  Subhas V. Naik 

Projected outcome:

  • In recent years there is a quantum jump in Eri cocoon production but there is no Techno-economically viable cocoon to yarn conversion technique in vogue.
  • It is proposed to develop a small scale spinning plant in association with a machinery  manufacturer.
  • This would help to transform Eri spinning  activity from a low income, part time job, low productivity into high productive, higher remunerative, full time job for medium scale Eri spinners in the North Eastern Region of India.

5. Title:

Development of New type of yarn (Void Silk) in reeling and spinning processes and its characterization 

Scientists Involved:

G. Hariraj,  M.M. Shirol, Kiran  B. Malali & Subhas V. Naik 

Projected outcome:

Presently development of different varieties of silk fabrics is being done with the help of design content, fabric geometry and usage of extra threads like zari etc., However demand for newer varieties of fabrics in the market is always on the raise. Even the big retailers are very much interested in such new products so that they can attach a new name to the product and advertise.

In this context it was thought to develop new type of yarn in the silk reeling process as well in the spinning process. In the silk reeling industry without altering the process if we can produce new type of yarn it helps both the reelers as well as the consumers. Similarly the spun silk which is not used much in silk sarees can be made to effectively use as porosity is introduced in the yarn due to removal of PVA yarn introduced in spinning process at the time of yarn / fabric processing. It is expected that such variety of yarn would enable extensive use of spun silk in silk handloom sector and also economics of spun silk production which in turn also helps reelers to get better price for their silk waste in Indian market itself.

6. Title:

Studies on cocoon cooking using high temperature & high pressure technology & also using chemicals for achieving better reeling performance & quality silk particularly from unfavourable season cocoons 

Scientists Involved:

Subhas V. Naik, Aswatha Reddy, M.A.Joseph & D. Ravikumar 

Projected outcome:

Cocoon cooking is very important process of Silk reeling and influences directly the raw silk recovery, productivity and quality of silk and hence economics of the filature. Improper cocoon cooking results in Poor recovery, Low productivity, poor quality and higher conversion cost. Further Cookers, reelers face hardship while reeling cocoons produced particularly under unfavourable climatic conditions. Therefore always there is scope for improvement in cocoon cooking process over the existing one.

Particularly when the reelability is poor cocoon cooking process plays a very dominant role in entire silk reeling process. The output of the study is anticipated to result in an effective method for better  cooking of cocoons particularly  produced under unfavourable conditions. This will help the reelers to realise significantly better silk recovery (i.e lower renditta) achieve better   quality of silk and productivity as compared to existing conventional cooking methods.
