Embodiment 1

[0030] Fresh cocoon silk reeling method comprises the following steps in the present embodiment:

[0031] (1) Put fresh silkworm cocoons purchased into the station into plastic baskets or bamboo baskets, and stack them at room temperature.

[0032] (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.

[0033] (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.

[0034] (4) The osmotic water-absorbing silkworm cocoons after low-temperature water suction and infiltration are boiled in a low-temperature, low-vapor-pressure, short-time process using a cocoon cooking machine. The steam pressure is 0.08MP, and the entire cocoon cooking time is 16 minutes. : ① impregnation at 50°C;...

Abstract

The invention discloses a fresh cocoon silk reeling method. The method comprises the following steps: stacking and storing fresh cocoons, and then sequentially performing cocoon mixing, cocoon peeling and cocoon selecting according to process requirements to obtain cocoons for silk reeling; putting the cocoons for silk reeling into a closed water tank, and performing low-temperature water suction permeation; cooking the permeated water-sucked cocoons subjected to the low-temperature water suction permeation by using a cocoon cooking machine, performing silk reeling by using an automatic silk reeling machine, and controlling the reeling speed; putting a small net into the water tank, performing negative-pressure water intake and suction, and then performing immersion treatment; finally, performing rereeling finishing, and packaging reeled silks. The fresh cocoon silk reeling method has the advantages of simplicity, quickness and low cost, the defects of an existing fresh cocoon silk reeling method are overcome favorably, the technical problem of influence on the performance of fresh cocoon raw silks caused by lower cohesion and poor abrasion resistance of the raw silks is solved, and the grade of the fresh cocoon raw silks is improved.

Description

technical field [0001] The invention relates to a method for processing silkworm cocoons, in particular to a fresh cocoon silk reeling method to improve 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] In the existing fresh cocoon reeling method, firstly, fresh cocoons are frozen and kept fresh, mixed peeling and screening, vacuum drainage and infiltration, automatic silk reeling, winding and forming. The method simp...
