Embodiment 1

[0024] Fresh cocoon silk reeling method comprises the following steps in the present embodiment:

[0025] (1) Put fresh silkworm cocoons purchased into the station into plastic baskets or bamboo baskets, and stack them at room temperature.

[0026] (2) The fresh silkworm cocoons stacked above are mixed, peeled and selected according to the process design requirements, and used as cocoons for silk reeling.

[0027] (3) Put the cocoons used for reeling into a closed water tank, and perform low-temperature water suction and infiltration for 4 minutes, the vacuum degree is 0.08MPa, the water temperature is 40°C, and the water surface is 4cm higher than the cocoons.

[0028] (4) Use an automatic silk reeling machine to reel the permeated and water-absorbed cocoons that have been sucked and infiltrated by low-temperature water. Suoxu soup temperature is 60°C, silk reeling soup temperature is 30°C, keep clear soup, pH value is 6.8; silk sheath length is 80mm, number of twist sheaths...

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 treatment method, in particular to a method for improving the cohesion performance of fresh cocoon reeled silk and raw silk, thereby improving the quality of fresh cocoon raw silk. Background technique [0002] Fresh cocoon raw silk is raw silk that is reeled directly from fresh cocoons. Fresh cocoon reeling does not require cocoon drying and cocoon boiling, which reduces the silk making process and reeling cost; the fresh cocoon reeling project reduces water vapor consumption and saves energy; and the application value of fresh silkworm chrysalis is high, which also increases The utilization effect of silkworm chrysalis by-products. Fresh cocoon raw silk can better maintain the unique style of natural raw silk due to less heat treatment. [0003] At present, the patents of the existing fresh cocoon reeling method are mainly invented by Bai Yanchuan, Liu Huifen, Zou Fangqing and Tan Zhihu (the method of silkwor...
