Embodiment 1

[0016] Embodiment 1——the method for improving silkworm cocoon yield

[0017] Before it carries out the silk reeling process on the silkworm cocoon, the following steps of pretreatment process are carried out on the silkworm cocoon:

[0018] A. Soak the cocoon in salt water with a concentration of 0.4% and a temperature of 40°C for 5 hours, then take it out, and rinse off the residual salt water on its surface;

[0019] B. Put the silkworm cocoons obtained through the treatment in step A into a container made of baking soda, polyethylene wax, sodium stearate, sodium perfluorosulfonate, sodium borate, sodium pyrophosphate, sodium tripolyphosphate, polyether and water. In the soaking solution, soak for 2 hours, then take it out, and rinse off the soaking solution remaining on its surface; wherein, by weight, 10 parts of baking soda, 5 parts of polyethylene wax, 1 part of sodium stearate, perfluorinated 4 parts of sodium sulfonate, 2 parts of sodium borate, 5 parts of sodium pyro...

Abstract

The invention discloses a method for improving a silk production rate of silkworm cocoons and belongs to the technical field of silk production of silkworm cocoons. The method disclosed by the invention comprises the following steps: soaking silkworm cocoons in brine for 1-5 hours before silk reeling of the silkworm cocoons; taking out the silkworm cocoons, and rinsing the residual brine on the surfaces of the silkworm cocoons; adding the silkworm cocoons treated in the step A into a soaking solution prepared from sodium bicarbonate, polyethylene wax, sodium stearate, perfiuoro-sodium sulfonate, sodium borate, sodium pyrophosphate, sodium tripolyphosphate, polyether and water, and soaking for 2-6 hours; and taking the silkworm cocoons out, and rinsing the residual soaking solution on the surfaces of the silkworm cocoons. According to the method disclosed by the invention, the silkworm cocoons are added into the brine at the specific temperature and concentration before silk reeling, sothat the surface tension is changed; and the silkworm cocoons are added into the soaking solution prepared from the sodium bicarbonate, polyethylene wax, sodium stearate, perfiuoro-sodium sulfonate,sodium borate, sodium pyrophosphate, sodium tripolyphosphate, polyether and water, so that the smoothness and toughness of silk in the silkworm cocoons are changed, and the silk production rate of thesilkworm cocoons in the silk reeling process is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of cocoon silk production, and in particular relates to a method for improving the silk yield of silkworm cocoons. Background technique [0002] Silkworm cocoon refers to the cocoon of silkworm, that is, the sac-shaped protective layer of silkworm pupal stage, which contains the pupal body. It is in different shapes such as oblong, elliptical girdle, spherical or spindle, or slightly constricted in the middle. The cocoons are white, yellow, light green, flesh red and other colors, about 3 to 4 cm long and 1.7 to 2.1 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 silkworm cocoon without eclosion contains one yellow-brown silkworm chrysalis and the light brown, shriveled silkworm skin that came off before pupae. [0003] The cocoon layer can be re...
