Abstract

The effect of difference in temperature between high temperature steam treatment and low temperature water permeation treatment and duration of high temperature steam treatment of cocoon cooking on reeling performance and quality characteristics of raw silk has been studied using Indian CSR race bivoltine hybrid cocoons. It is observed that both difference in temperature between high temperature stearn treatment and low temperature water permeation treatment and duration of high temperature steam treatment have a significant influence on reelability, filarnent length, non-broken filarnent length, raw silk%, neatness, cleanness, tenacity, elongation and cohesion of raw silk. Results indicate that 10°C ∼15°C difference in temperature between high temperature stearn treatment and low temperature water permeation treatment with 90∼93°C temperature and 1.5 to 2.0 min duration at high temperature stearn treatment zone of cocoon cooking give better reeling performance and quality raw silk from CSR race bivoltine hybrid cocoons.
