Abstract

The influence of rotary traverse mechanism speed, reel speed and number of cocoons to be reeled for the production of web structured bulky raw silk has been studied using Box-Behnken response surface design. The hot air dried multi-bivoltine cocoons (PM × NB4D2 race) treated at different rotary traverse mechanism speed, reel speed and number of cocoons to be reeled for the production of bulky raw silk have been found to have significant influence on reeling characteristics, viz. bulkiness (diameter) and productivity and on quality characteristics, viz. average size, size deviation and tenacity of web structured bulky raw silk. However, the other process parameters viz., renditta, waste generated during reeling, maximum size deviation and elongation of bulky raw silk did not have significant influence on production of web structured bulky raw silk. The study clearly shows that the based on the rotary traverse mechanism speed, reel speed and number of cocoons different qualities of web structured bulky raw silk with different productivity levels and bulkiness could be produced using inferior quality multi-bivoltine cocoons.
