Silkworm cocoon processing method capable of increasing reelability percentage and silk yield of silkworm cocoons

Abstract

The invention discloses a silkworm cocoon processing method capable of increasing reelability percentage and silk yield of silkworm cocoons. The processing method comprises the following steps: (1) selecting fresh silkworm cocoons under the condition that the illumination intensity is 2700 to 3100 lux, and removing light defective cocoons, double cocoons and rotten cocoons; (2) putting the silkworm cocoons in the step (1) into a vacuum pump, vacuumizing the vacuum pump until the vacuum degree is 0.0101 to 0.0102 Mpa, adding an aid I at the temperature of 32 to 35 DEG C, and enabling water to enter to be 6 to 8 cm higher than the cocoons, wherein the permeating and water absorbing time is 6 to 10 minutes; (3) cooking the silkworm cocoons in the step (2), and controlling the temperature of the cocoon cooking water to 55 to 65 DEG C, the time to 6 to 8 minutes and the PH to be 4.9 to 5.7 during cocoon cooking; (4) putting the silkworm cocoons in the step (3) into warm water at the temperature of 25 to 30 DEG C, adding an aid II in an amount which is 0.6 to 0.9 percent of the weight of the warm water and soaking for 30 to 60 minutes; and (5) cooling the silkworm cocoons obtained in thestep (4) to room temperature by using water at the temperature of 30 to 40 DEG C and reeling silk. By adopting the method, the development of silkworm cultivation and silk industries is promoted.

Description

technical field

[0001] The invention relates to the field of agriculture, in particular to a silkworm cocoon processing method which improves the unwinding rate and silk yield of silkworm cocoons. Background technique

[0002] Silkworm cocoons refer to the cocoons of silkworms. The sac-shaped protective layer of the silkworm pupal stage, containing the pupal body. The cocoon layer can be reeled, and the cocoon clothes and the reeled waste silk can be used as raw materials for silk cotton and silk spinning.

[0003] Silkworm cocoons are in different shapes such as oblong, elliptical waist-shaped, spherical or spindle-shaped, or slightly constricted in the middle. The cocoons are white, yellow, light green, flesh red and other colors, about 3-4 cm long and 1.7-2.1 cm in diameter. cm, the surface is white, with irregular wrinkles, and there are attached silks, which are fluffy. The silk pattern on its inner wall is very regular. Lightweight and tough, not easy to tear. The...
