A STUDY OF COCOON FILAMENT OBTAINED IN RE-FEEDING

Abstract

This article provides information about cocoon automatic- and mechanical cocoon reeling machines in silk manufacturing enterprises of our republic, as well as the state of cocoon cultivation.
The technological properties of the cocoon shells grown repeatedly in local conditions of the hybrids of Chinese silkworms, and the compliance of the raw silk produced from them with the requirements of the international standard have been studied.
The compensation period in raw silk production is analyzed from a theoretical point of view. The factors infl uencing the linear density of raw silk during reeling, the methods of controlling the linear density of raw silk produced in mechanical and automatic machines are solved theoretically and according to the results of practice, including the time spent to fi ll the broken cocoon threads and the amount of defective length determined in 100 grams of cocoon thread. The quality of raw silk that can be obtained from cocoons grown in diff erent seasons was analyzed based on experimental results. It has been proven from a practical point of view that the probability of producing high-quality raw silk from the cocoons of the III-IV seasons is low.
