Embodiment 1
[0025] A method for processing silkworm cocoons to improve the unwinding rate and silk yield of silkworm cocoons, the processing method comprising:
[0026] ①Place the fresh cocoons under the conditions of light intensity of 2700-3100lux to select, and remove the secondary cocoons, double cocoons, and lower rotten cocoons;
[0027] ②Put the silkworm cocoon through step ① into the vacuum pump first, and then after the vacuum pump is evacuated to 0.0101-0.0102Mpa, add the coco-based glucoside aqueous solution with a concentration of 6.1wt% at 32-35°C. ~8cm, the time of penetration and water absorption is 6~10min;
[0028] ③ Boil the cocoons of the silkworm cocoons that have passed step ②. When cooking the cocoons, control the temperature of the cocoon boiling water to 55-65°C, the time to 6-8 minutes, and the pH to be 5.2;
[0029] ④Put the cocoons of step ③ into warm water at 25°C to 30°C, and then add auxiliary agent 2 with a mass of 0.72% of the warm water, wherein auxiliary...
Embodiment 2
[0032] A method for processing silkworm cocoons to improve the unwinding rate and silk yield of silkworm cocoons, the processing method comprising:
[0033] ①Place the fresh cocoons under the conditions of light intensity of 2700-3100lux to select, and remove the secondary cocoons, double cocoons, and lower rotten cocoons;
[0034] ②Put the silkworm cocoon through step ① into the vacuum pump first, and then after the vacuum pump is evacuated to 0.0101-0.0102Mpa, add an aqueous solution of sodium dodecylsulfonate with a concentration of 4.9-7.8wt% at 32-35°C. 6-8cm higher than the cocoon, the time for penetration and water absorption is 6-10 minutes;
[0035] ③ Boil the cocoons of the silkworm cocoons that have passed step ②. When cooking the cocoons, control the temperature of the cocoon boiling water to 55-65°C, the time to 6-8 minutes, and the pH to be 5.2;
[0036] ④Put the cocoons of step ③ into warm water at 25°C to 30°C, and then add auxiliary agent 2 with a mass of 0.7...
Embodiment 3
[0039] A method for processing silkworm cocoons to improve the unwinding rate and silk yield of silkworm cocoons, the processing method comprising:
[0040] ①Place the fresh cocoons under the conditions of light intensity of 2700-3100lux to select, and remove the secondary cocoons, double cocoons, and lower rotten cocoons;
[0041] ②Put the silkworm cocoon through step ① into the vacuum pump first, and then after the vacuum pump is evacuated to 0.0101-0.0102Mpa, add an aqueous solution of fatty acid glyceride with a concentration of 4.9-7.8wt% at 32-35°C. ~8cm, the time of penetration and water absorption is 6~10min;
[0042] ③ Boil the cocoons of the silkworm cocoons that have passed step ②. When cooking the cocoons, control the temperature of the cocoon boiling water to 55-65°C, the time to 6-8 minutes, and the pH to be 5.2;
[0043] ④Put the cocoons of step ③ into warm water at 25°C to 30°C, and then add auxiliary agent 2 with a mass of 0.72% of the warm water, wherein aux...
