Abstract

The invention relates to the technical field of silk reeling texture, and discloses a silk reeling method adopting dried cocoons. The problems that a traditional silk reeling adopting dried cocoons islow in production efficiency, raw silk is rough, and the quality is poor are solved. The method comprises the specific steps of soaking dried cocoon shells by adopting clear water, soaking the driedcocoon shells by adopting limewater, conducting vacuum infiltration by adopting mixed infiltrating liquid A, boiling the dried cocoon shells for 20-40 min by adopting alkaline water, adding mixed infiltrating liquid B for infiltrating treatment, soaking the dried cocoon shells by adopting circulating clear water, thoroughly flushing the dried cocoon shells by adopting clear water, and conducting silk reeling after dehydration treatment, the temperature of cocoon beating water is 50-60 DEG C, the temperature of cocoon arranging water and reeling water is 30-35 DEG C, and the pH value is 7-7.5;the silk reeling method adopting the dried cocoons can make cocoon shell sericin swell and dissolve appropriately, the adhesive force among cocoon silk is reduced appropriately, in the later silk reeling process, silkworm cocoons can be subjected to reelability and cocoon beating easily, and raw silk is clean, good in embracing, and unique in gloss, can resist wrinkles, and is good in dyeing performance, high in color fastness and economic value, and low in consumption of raw cocoon materials.

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...
