Abstract

The invention relates to the technical field of silk reeling and textiles, and discloses a cocoon reeling method; it solves the problems of low production efficiency and poor quality of raw silk in traditional cocoon reeling; the specific steps include soaking dry cocoon shells in clear water, soaking in lime water, Vacuum infiltration with mixed permeate A, boil with alkaline water for 20‑40min, add mixed permeate B again for infiltration treatment, then soak in circulating water and rinse with clean water, dehydrate and reel silk, the temperature of the soup is 50 ‑60°C, the temperatures of Lixu soup and reeling soup are both 30‑35°C, and the pH value is 7‑7.5; the cocoon reeling method of the present invention can make the cocoon layer sericin swell and dissolve moderately, and the glue between cocoon silk The effort is appropriately reduced, so the cocoons are easy to loosen and thread during the subsequent silk reeling process. The raw silk is clean and cohesive, with unique luster, wrinkle resistance, good dyeability, high color fastness, high economic value, and low consumption of raw cocoons.

Description

technical field [0001] The invention relates to the technical field of silk reeling and textiles, in particular to a method for reeling silk from dried cocoons. Background technique [0002] With the development of science and technology, especially the application of new equipment such as high-speed looms in weaving, new requirements have been put forward for the quality of raw silk: to improve the strength, cohesion, cleanness and cleanliness of raw silk, so that it can adapt to the high tension of high-speed looms , Strong friction requirements. The traditional processing of fresh cocoon silk is to reel the silk directly without drying or boiling the cocoon. This process reduces the number of silk-making links, reduces costs and energy consumption, and at the same time maintains the unique original properties of cocoon silk. The cocoon silk processed by the production method has low viscosity of sericin, poor bonding degree between cocoon silk, high content of sericin on...
