Sericulture is the rearing of Silkworm for the production of natural silk.
Sericulture has tremendous potential for further growth and expansion elsewhere in India. It accelerates integrated rural development by providing gainful employment in rural areas leading to economic self reliance which in turn raise the standard of living of people in villages.
Steps in Silk Reeling Process
Silk reeling process includes the following steps:
1. Stifling Process
2. Cocooing or Cocoon Boiling
3. Silk Reeling
This is a pre-reeling process by which the pupae inside the cocoons are killed, without compromising on the quality of silk. Steam- sifting is commonly practiced in pre-reeling process.
Cocooing or Cocoon Boiling
Here the cocoons are boiled in water to soften the shell and also to dissolve the sericin gum for the purpose of smooth reeling.
The two silk filaments produced by two silk glands are cemented together by sericin at the spinneret, constitute the bifilar thread called Bave. The process of reeling involves the unwinding of the bave of the cocoons. The reeling is done either in the traditional way with a charakha or with filature where reeling is done with power driven reels.
Cocoon Markets in India
The important cocoon markets and reeling centres in Karnataka are Ramanagaram and sidlaghatta. Ramanagaram is the largest cocoon market in India and sidlaghatta is indeed famous for its excellent reeling with regard to quality of silk produced.
Productivity of raw silk from Bivoltine races is much higher than that of Multivoltine races.
