This article is devoted to the study of the drying of cocoons, divided into three groups, at a temperature of 90 ℃ for different periods. To study the influence of various factors on the production of high-quality silk yarn, single cocoon unwinding was carried out under the influence of temperature. Samples were selected from 300 cocoons belonging to the Guzal I and Guzal II breeds and hybrids, which were brought from the Silk Research Institute to the department of silk and spinning technology. The samples were divided into three groups and the initial weight of each cocoon was measured. The second and third groups of cocoons were first weighed, and then their pupa were processed in a dryer to determine the humidity available at the institute at a temperature of 90 ℃ for one hour and four and a half hours. After this process, the cocoon weight was measured again. The prepared cocoon samples were unwound on a single-winding machine available at our department and their properties such as silkiness and unwinding were analyzed. Based on the experimental results, the cocoon parts were calculated based on samples divided into three groups, and the length of the silk thread spun from the cocoon was determined. The indicators of the yield of other parts of the cocoon are presented in the table.
