Technology process for preparing colour silk by natural colour cocoon, colour fixing and reeling

Abstract

This invention is a technique method of making color silk using natural color cocoon filature. By preparing natural color cocoon-soaking-fixation-qualitative-filature-collating after filature, we can get color silk finally. The color silk made by this method don't discolor when in the boiling water, also discolor in the alkali water, the practical alkali rate is below 10%. It has high use value, low cost, short technological process.

Description

technical field [0001] The invention belongs to the silk spinning industry, in particular to a process for reeling colored silk from natural cocoon clothing through color fixation. Background technique [0002] Natural colored cocoons have been successfully bred in many places in my country, but to reel natural colored cocoons into colored silk with practical functions, that is, it can basically not decolorize in boiling water or weak acid and weak alkali solutions, and has good color fastness. It is impossible to reel such colored silk by using traditional techniques. The reason is that no matter what method is used to raise natural colored cocoons, the structure of the silk has not changed, and it is still composed of sericin-coated silk fibroin. The characteristic of being soluble in water and more soluble in hot water has not changed, but the color elements of natural colored cocoons are distributed in the sericin. The current silk reeling and cocoon ...

[0002] Natural colored cocoons have been successfully bred in many places in China, but to reel natural colored cocoons into colored silk with practical functions, that is, it can basically not decolorize in boiling water or weak acid and weak alkali solutions, and has good color fastness. It is impossible to reel such colored silk by using traditional techniques. The reason is that no matter what method is used to raise natural colored cocoons, the structure of the silk has not changed, and it is still composed of sericin-coated silk fibroin. The characteristic of being soluble in water and more soluble in hot water has not changed, but the color elements of natural colored cocoons are distributed in the sericin. The current silk reeling and cocoon boiling process can remove part of the sericin, and the remaining part of the sericin is only for protection The role of silk fibroin, but it does not fix the sericin. Therefore, it is difficult to keep the natural color of the silk reeled by the current silk reeling process, even if some methods temporarily preserve it during the silk reeling process. However, if it is boiled in boiling water or in a weak acid or weak alkali solution, its color will dissolve in water together with sericin and lose its color, so it is even more impossible to make silk with natural color into textile products.
