Embodiment 1

[0025] Fresh cocoon silk reeling method comprises the following steps in the present embodiment:

[0026] (1) Put fresh silkworm cocoons purchased into the station into plastic baskets or bamboo baskets, and stack them at room temperature.

[0027] (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.

[0028] (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.

[0029] (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. The temperature of Suoxu soup is 60°C, and the temperature of silk reeling soup is 30°C. Keep the clear soup. When the silk reeling soup turns yellow, the w...

Abstract

The invention discloses a method for increasing the whiteness degree and improving the softness of raw silk formed by fresh cocoon silk reeling. The method includes the steps that fresh cocoons are stacked and stored, and then sequentially mixed, stripped, and sorted according to technology requirements, so that silk reeling cocoons are obtained; the silk reeling cocoons are placed in an airtight water tank and permeated by low-temperature water in a suction mode; after permeation by the low-temperature water in the suction mode, silk reeling is performed on the permeated water-absorption silkworm cocoons through an automatic silk reeling machine, and silk reeling water is kept clear, or replaced with clear water; small nets are placed in the water tank, absorb water through negative-pressure water entering, and then are soaked, and meanwhile additives are adopted for treatment; finally, re-reeling, arranging, skein twisting and packaging are performed. The method has the advantages of being simple, rapid and low in cost, and is beneficial to overcoming the defects in existing fresh cocoon silk reeling, solving the problems that raw silk is not soft enough in hand feeling, the surfaces of the raw silk are rough, and the color of the raw silk is not uniform, so that the performance of the raw silk is affected, and improving the quality of the fresh cocoon raw silk.

Description

technical field [0001] The invention relates to a method for treating fresh cocoons, in particular to a method for improving the whiteness and softness of fresh cocoon reeled raw silk and improving the quality of fresh cocoon reeled 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 on fresh cocoon reeling are mainly invented by Bai Yanchuan, Liu Huifen, Zou Fangqing, and Tan Zhihu (the method of silkworm fresh cocoon reeli...
