ARTICLE ANNOTATION

quote
This article explores thread thinning, roughness, total, and continuous length by individual unwinding of defective cocoons obtained by breeding domestic Navroz-1 cocoons and Chinese hybrids grown in our republic. It is justified that the output of various types of silk fabrics can be ensured by increasing the amount of raw silk by unwinding defective cocoons. To achieve this goal, the research was carried out in two ways: raw silk of high linear density (16.60 tex) was obtained using a mechanical cocoon-winding machine, and 10.75 and 13.33 tex were obtained by means of an automatic machine. Certain technological parameters and modes for machines are experimentally presented in the tables. The quality of raw silk with a high linear density, produced by a new method, was tested in accordance with the requirements of the current state standard, O‘zDST 3313:2018, and positive results were obtained, corresponding to class A obtained by means of a mechanical machine and class 2A obtained from an automatic machine. For the production of raw silk with a high linear density of 10.75 and 13.33 tex using automatic cocoon winding machines, appropriate changes were made in the control apparatus and theoretical calculations were carried out. The resulting raw silk of high linear density is recommended for use in the making of carpet threads; moreover, it can be used in the making of various silk suit fabrics.
