Abstract

The invention discloses a method for improving cohesion of fresh cocoon reeling raw silk. Cocoon mixing, cocoon stripping and cocoon assorting are sequentially carried out on fresh cocoons according to process requirements after the fresh cocoons are stacked and stored, and reeling cocoons are obtained; the reeling cocoons are placed in a sealed water tank for low-temperature water suction permeation; water-permeable water-absorbing cocoons after low-temperature water suction permeation are reeled by means of an automatic reeling machine, and winding speed is controlled; a small net is placed in the water tank, negative-pressure water incoming and water absorbing are carried out firstly, and then dipping is carried out, finally re-reeling and sorting are carried out, and skein twisting and packaging are carried. The method has the advantages of being simple, quick and low in cost. Defects of existing fresh cocoon reeling are overcome, the technical problems that cohesion is poor, friction resistance of the raw silk is poor, and performance of the fresh cocoon raw silk is influenced are solved, and the grade of the fresh cocoon raw silk is improved.

Description

Technical field [0001] The invention relates to a fresh cocoon processing method, in particular to a method for improving the cohesion performance of the fresh cocoon reeling raw silk and improving the quality of the fresh cocoon raw silk. Background technique [0002] Fresh cocoon raw silk is raw silk that is directly reeled from fresh cocoons. Fresh cocoon silk reeling does not require cocoon drying and cooking, which reduces the link of silk production and reduces the cost of silk reeling; the fresh cocoon silk reeling project reduces water vapor consumption and saves energy; and the application value of fresh silkworm pupae is high and improves The utilization effect of silkworm pupa by-products. Since fresh cocoon raw silk is less subjected to heat treatment, it can better maintain the unique style of natural raw silk. [0003] At present, the existing patents for the silk reeling method of fresh cocoons are mainly invented by Bai Yanchuan, Liu Huifen, Zou Fangqing, and Tan ...
