Abstract

The invention discloses a method for increasing cohesive force of fresh cocoon filaments. The method comprises the following steps: A) putting the fresh cocoon filaments into a refrigerator, filling nitrogen into the refrigerator and treating the fresh cocoon filaments at low temperature; B) putting the fresh cocoon filaments treated in the step A) into a soaking pool for soaking; C) putting the fresh cocoon filaments treated in the step B) into a stirring jar, heating and stirring; D) putting the fresh cocoon filaments treated in the step C) into a vacuum tank for carrying out vacuum infiltration; and E) cleaning and air-drying the fresh cocoon filaments treated in the step D). According to the method provided by the invention, the defects of the prior art can be overcome, and the cohesive force of the fresh cocoon filaments can be further increased.

Description

technical field [0001] The invention relates to the technical field of raw silk processing, in particular to a method for improving cohesion of fresh cocoon silk. Background technique [0002] The cohesion of raw silk refers to the degree of difficulty in breaking apart the cocoon threads that make up raw silk after friction, reflecting the firmness of the cocoon threads that make up raw silk. The cohesion of raw silk has a lot to do with the cocoon cooking process. The sericin swelling of uncooked cocoon silk is not sufficient, and the cocoon silk cannot be wrapped together when the raw silk is reeled, and the cocoon silk has poor bundling property; The silk fibroin and sericin of boiled fresh cocoon silk have poor binding force, so the sericin is easy to fall off during weaving, and after the pre-weaving treatment, the surface of the silk strip is uneven and fluffy, the silk strip splits, and the fresh cocoon silk cohesion The decline in indicators has become a major prob...
