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 n

Embodiment 1

[0007] Embodiment 1. Get 30kg of empty cocoons or dry solid cocoons stored under dark, ventilated and dry conditions, and process according to the following procedures: a. Water immersion: pour into a vacuum tank, start the vacuum pump, and evacuate to 0.04-0.06Mpa after , close the exhaust valve, add hot water at 90-100°C to the vacuum tank, the pH of the hot water is 7.2-7.5, the water inlet height should be 2-3 cm soaked in silkworm cocoons, after soaking for 15 minutes, repeat pumping Vacuum, water and soak for 2-5 times until the silkworm cocoon absorbs water and reaches saturation. During this period, the temperature of the hot water is controlled between 80-90°C, and the water is drained after soaking for 0.5-1 hour at the end; b. Drug release: add 270kg of solution Shuye Jieshu, Jieshu liquid is: add 9kg sodium silicate, 14kg sodium carbonate, 1.0kg red oil, 0.8kg borax and 22kg hydrogen peroxide to every 1000kg water, mix and dissolve, the empty cocoon or dry solid coc...

Embodiment 2

[0009] Embodiment 2. get 30kg of live pupal cocoons stored under dark, ventilated and dry conditions, and process according to the following procedures: a. water immersion: fully soak in water at room temperature for 4-8 hours; b. medicine release: add 250kg solution Shuye Jieshu, Jieshu liquid is: add 15kg of sodium silicate, 6kg of sodium carbonate, 0.6kg of red oil, 1.0kg of borax and 16kg of hydrogen peroxide into every 1000kg of water, and mix and dissolve. Drainage after 2-4 hours of relaxation; c. Take out the silkworm cocoons that have been relieved and reel them manually or mechanically; d. After re-shaking and sorting, process them into silk; Drying is the finished product.

[0010] The finished silk has been tested by an authoritative organization, and the indicators such as silk strength, cohesion, fineness, appearance and roughness have reached A grade or above, which fully meets the national standard.

Embodiment 3

[0011] Embodiment 3. Get 30kg of empty cocoons or dry solid cocoons stored under dark, ventilated and dry conditions, and process according to the following procedures: a. water immersion: as in Example 1; b. drug relief: add 260kg of relief liquid Jieshu, Jieshu liquid is: add 12kg sodium silicate, 10kg sodium carbonate, 0.8kg red oil, 0.6kg borax and 28kg hydrogen peroxide to every 1000kg water, mix and dissolve. After relieving the drug for 20-30 minutes at 40°C, add 5kg of hydrogen peroxide for every 30kg of silkworm cocoons, and release it for a second time at 30-50°C for 20-25 minutes; c. Take out the cocoons that have been relieved and reel them manually or mechanically ; d. After re-shaking and finishing, it is processed into silk.

[0012] The finished silk has been tested by an authoritative organization, and the indicators such as silk strength, cohesion, fineness, appearance and roughness have reached A grade or above, which fully meets the national standard.

Abstract

A silk reeling technology for non-flesh cocoons, dried cocoons and alive pupa cocoons is achieved by: vacuumizing ,dipping non-flesh cocoons and dried cocoons in hot water, or alive pupa Immersing in water at atmosphere, processing in a relaxing liquid containing sodium silicate, sodium carbonate, red oil, borax, hydrogen peroxide, and water, reeling, and settling to make silk. The advantage of this technology is not only full use of wastes from traditional process, but also reeling the alive pupa cocoon beneficially.

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...
