Research of Preparation of Defect Cocoons for Unreeling and Technology for Producing Silk-Raw with High Linear Density

Abstract

The article examines the yield of defective cocoons according to the feeding season of the silk moth and hybrids, determines the increase in the yield of defective cocoons in the second and third season by 2 and 6% compared to the first season. It is proved that in order to obtain raw silk of grade 4A; cocoons must be unwound separately by grades. Determining the indicators of defective cocoons after processing, the possibilities of unwinding with a speed of 110-130 m / min were revealed. Studying the time of filling cocoons in a rose while regulating leukemic density, the compaction time was determined for raw silk with a high linear density and it was recommended to use the obtained raw silk for the production of silk carpets.
