Problems solved by technology

Although the traditional silk reeling method has a long history and mature technology, it is only suitable for mature and plump fresh silkworm cocoons. Some empty cocoons and dry solid cocoons are generally used as leftovers and cannot be fully utilized, or even if they are barely used for silk reeling, However, during the unwinding process, the unwinding process is not complete, and cocoons are prone to appear, and the quality of reeling silk is difficult to meet the quality standard, or silk reeling cannot be carried out at all.
In addition, the traditional silk reeling process is to cook fresh silk cocoons and reel them to obtain silk. In these processes, live pupae become dead pupae, and the economic benefits are greatly reduced.

Embodiment 1

[0018] Embodiment 1. get the empty cocoon or dry solid cocoon 100kg stored under dark, ventilated and dry conditions, process according to the following procedures: a. Pour the solid cocoon into the vacuum tank, start the vacuum pump, and after vacuuming to 0.04-0.06Mpa, close the exhaust valve, open the water inlet valve, and pump hot water at 90-100°C into the vacuum tank, the pH of the hot water is 7.0 -8.0, the amount of water intake should be 2-3 cm soaked in silkworm cocoons, drain after soaking for 15 minutes, and control the temperature of hot water during the period between 80-95 ° C; according to the fiber content of empty cocoons or dry solid cocoons and the convergence of sericin For the degree of coagulation, repeat the process of vacuuming, water intake and soaking for 1-5 times until the silkworm cocoon absorbs water and reaches saturation; b. Drug relief: the composition of the relief liquid is: add 9kg sodium silicate, 14kg sodium carbonate, 1.0kg of red oil, ...

Embodiment 2

[0022] Embodiment 2. get the live chrysalis cocoon 100kg stored under the dark, ventilated and dry conditions, process according to the following procedures: a. water immersion: the live chrysalis cocoons stored under the dark, ventilated and dry conditions are poured into the vacuum tank, Start the vacuum pump, after vacuuming to 0.04-0.06Mpa, close the pumping valve, open the water inlet valve, and pump hot water at 20-30°C into the vacuum tank. It is advisable to pass silkworm cocoons for 2-3 cm; fully soak in water at room temperature for 0-4 hours and then drain; according to the size of live pupa cocoon fibers and the degree of convergence and solidification of sericin, fully soak in water for 4 hours at room temperature and then drain; b. Shu: adjust the composition of the unwinding liquid and control the unwinding conditions according to the size of live pupae cocoon fibers and the degree of sericin convergence and solidification; Red oil, 1.5kg of borax, 50kg of hydro...

Embodiment 3

[0024] Embodiment 3. get the empty cocoon or dry solid cocoon 100kg stored under dark, ventilated and dry conditions, process according to the following procedures: a. Pour the solid cocoon into the vacuum tank, start the vacuum pump, and after vacuuming to 0.02-0.04Mpa, close the exhaust valve, open the water inlet valve, and pump hot water at 80-90°C into the vacuum tank, the pH of the hot water is 7.0 -8.0, the amount of water intake should be 2-3 cm soaked in silkworm cocoons, drain after soaking for 15 minutes, and control the temperature of hot water during the period between 80-95 ° C; according to the fiber content of empty cocoons or dry solid cocoons and the convergence of sericin The degree of coagulation, repeat the process of vacuuming, water intake and soaking for 1-5 times until the silkworm cocoon absorbs water and reaches saturation; b. Drug relief: the composition of the relief liquid is: add 15kg sodium silicate, 6kg sodium carbonate, 0.6kg of red oil, 1.5kg...

Abstract

This invention relates to hollow pulp cocoon, dried cocoon and live cocoon filature process, which vacuums the waste hollow pulp cocoon or dried cocoon discarded in traditional process and dips the cocoon under room temperature after being boiled and goes through dispel liquid composed of sodium silicate, sodium carbonate, red oil, borax, hydrogen dioxide solution, surface activity agent and water and finally through filature and shading and processing into silk.

Description

technical field [0001] The invention relates to a silk reeling process of silkworm cocoons, in particular to a silk reeling process of empty cocoons, dry solid cocoons and live pupa cocoons. Background technique [0002] Tussah silkworm cocoons belong to the family Esteridae, and its whole body is full of treasures. The silk extracted from it is a green fabric, which can be used as high-end decorations and raw materials for various textiles. Tussah silk reeling has a long history of civilization from ancient times to the present. Although the traditional silk reeling method has a long history and mature technology, it is only suitable for mature and plump fresh silkworm cocoons. Some empty cocoons and dry solid cocoons are generally used as leftovers and cannot be fully utilized, or even if they are barely used for silk reeling, However, in the unwinding process, the unwinding is incomplete, and cocoons are prone to appear, and the quality of reeling silk is difficult to rea...
