DEVELOPMENT OF BULKY SILK YARN IN WEB SILK REELING PROCESS

Abstract

CSTRI, CSB, Bengaluru has developed a concept of web silk reeling machine for imparting bulkiness during the raw silk the production using differential traverse mechanism. The process variables viz., differential rotary traverse mechanism speed, reel speed and number of cocoons significantly influences the both reeling and quality characteristics of bulky raw silk and imparts desired bulkiness in the raw silk viz., diameter (bulkiness), productivity average size, size deviation and tenacity of bulky raw silk. The analysis of results also indicate that 3:1 combination between rotary traverse speed and reel speed produces good quality web structured bulky raw silk. The yarn produced using this machine was three times bulkier than the yarn produced from same number of cocoons in regular silk reeling machine. The silk fabrics produced using bulky raw silk in weft has shown better properties in terms of tensile and tear strength, crimp percentgae, abrasion resistance and drape co-efficient, which in turn result in better comfort properties.
