Visited to different silk dyeing clusters to study the silk warp dyeing and strapping process. Collected detailed information like, process of dyeing different colours, dyeing time, production etc., Had technical discussion with 03 vendors. Appraised them on method / process of mechanization of silk warp strapping process.

1. PROJECT TITLE
“STUDIES ON WEAVING PERFORMANCE AND FABRIC
PROPERTIES FOR RAW SILK REELED FROM MALE AND FEMALE
COCOONS OF BIVOLTINE AND MULTIVOLTINE HYBRIDS”
PROJECT TEAM:
Dr. Subhas.V.Naik, Director - Proj. Co-ordinator/ C.I.
Sri. M.G.Mahesh, Sc-D, - Principal Investigator
BUDGET: 7.50 lakhs
Duration: 2 years
CENTRAL SILK TECHNOLOGICAL RESEARCH INSTITUTE CENTRAL SILK BOARD, BANGALORE

2. Objective:
• Developing of fabrics using the raw silk produced
from male and female cocoons and to study its
twisting /weaving performance.
• To study the properties of developed fabric and
their dyeing performance separately.

3. Definition of Problem:
• In the present scenario in India silk yarn reeling is carried by mixer
of both male and female cocoons.
• The project report on “Studies on reeling performance and
quality characteristics of raw silk from male and female cocoons”
signifies that there is difference in quality of male and female
cocoons particularly in terms of raw silk yield and filament quality.
• The outcome of project indicates that the yarn reeled from male
cocoons is superior in grade compared to female cocoons in case
of Bi-Voltine and Multivoltine Hybrids.
• Based on the yarn reeled during the process of earlier project a
study is essential to assess its performance in weaving activity and
evaluate the fabric quality characteristics.
• This study will lead for development of superior quality fabric, to
be used for specific purposes.

4. Current status of the problem:
• In the present scenario in India silk yarn reeling is
carried by mixer of both male and female cocoons.
• At present there is demand in the silk industry for the
bulk quantity of superior grade raw silk consistently.
In order to produce best quality of silk, cocoon
characters like Shell Ratio, Reelability, Average
Filament length, Non-breakable Filament length,
Single cocoon filament denier play significant role.
• From the extensive research, it has been established
recently, that Raw silk yield and quality characteristics
of raw silk are significantly better in the case of Male
cocoons compared to the Female cocoons.

5. Current status of the problem Contd:
The results show that male cocoons perform better in
all aspects compared to the female cocoons.
This study will be helpful in production of
superior quality of fabric for particular end use.

6. Methodology / Plan of work:
To study the:
• Performance of yarns reeled from male/ female cocoons in
winding, doubling and twisting processes.
• Performance of twisted yarns in fabric weaving on
powerloom.
• The woven fabrics for its quality and other characteristics
through required tests.
• Data generated in this study.
• Submission of report with conclusive notes.

7. Expected Outcome:
The study will help in:
• Production of superior grade of fabric.
• Design of superior quality of fabric for specific end use.
• The new products to the industry.
• Boosts the industry in production of excellent grade fabrics.
