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.
