Embodiment 1

[0014] Embodiment 1——Improving the method of unwinding silk length of cocoon silk

[0015] It includes the following steps:

[0016] Put the silkworm cocoons into the cocoon cooking bucket, add water and cocoon cooking aids, and cook for 30 minutes at a temperature of 30°C and a pressure of 1 MPa. The amount of the cocoon cooking aids accounted for 0.5% of the mass of the water ; Wherein, the cocoon cooking auxiliary agent is made of the following components by weight: 10 parts of cowhide paste, 20 parts of rosin glyceride, 15 parts of sodium chloride, 10 parts of silicone oil, 12 parts of sorbitan, 5 parts of sodium borate parts and 50 parts of ethanol.

[0017] After silk reeling, the average unwinding rate of the silkworm cocoons treated in this embodiment can reach 87%, and the average unwinding silk length can be as long as 910m.

Embodiment 2

[0018] Embodiment 2——Improving the method of cocoon silk unwinding silk length

[0019] It includes the following steps:

[0020] Put the silkworm cocoons into the cocoon cooking bucket, add water and cocoon cooking aids, and boil them for 35 minutes at a temperature of 32°C and a pressure of 3 MPa. The amount of the cocoon cooking aids accounted for 0.6% of the mass of the water Wherein, the cocoon cooking auxiliary agent is made of the following components by weight: 11 parts of cowhide paste, 22 parts of rosin glyceride, 16 parts of sodium chloride, 11 parts of silicone oil, 13 parts of sorbitan, 6 parts of sodium borate parts and 55 parts of ethanol.

[0021] After silk reeling, the average unwinding rate of the silkworm cocoons treated in this embodiment can reach 87.1%, and the average unwinding silk length can be as long as 911m.

Embodiment 3

[0022] Embodiment 3——Improving the method of cocoon silk unwinding silk length

[0023] It includes the following steps:

[0024] Put the silkworm cocoons into the cocoon cooking bucket, add water and cocoon cooking auxiliary agent, and cook for 40 minutes at a temperature of 34°C and a pressure of 5 MPa. The amount of the cocoon cooking auxiliary agent accounts for 0.7% of the mass of the water ; Wherein, the cocoon cooking auxiliary agent is made of the following components by weight: 12 parts of cowhide cream, 24 parts of rosin glyceride, 17 parts of sodium chloride, 12 parts of silicone oil, 14 parts of sorbitan, 7 parts of sodium borate parts and 60 parts of ethanol.

[0025] After silk reeling, the average unwinding rate of the silkworm cocoons treated in this embodiment can reach 87.6%, and the average unwinding silk length can be as long as 915m.

Abstract

The invention discloses a method for increasing reelability filament lengths of cocoon filaments, and belongs to the technical field of silkworm cocoon filament making. The method comprises the following step: adding a cocoon cooking auxiliary in a process of putting cocoons into a cocoon cooking bucket and adding water for cooking, wherein the cocoon cooking auxiliary is prepared from the following components in parts by weight: 10 to 16 parts of cattlehide paste, 20 to 35 parts of glycerol ester of rosin, 15 to 20 parts of sodium chloride, 10 to 15 parts of silicone oil, 12 to 18 parts of sorbitan, 5 to 10 parts of sodium borate and 50 to 70 parts of ethanol. The cocoon cooking auxiliary prepared from the cattlehide paste, the glycerol ester of rosin, the sodium chloride, the silicone oil, the sorbitan, the sodium borate and the ethanol is added in a cocoon cooking process, so that the aim of increasing the reelability of the cocoon filaments is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of silkworm cocoon silk making, and in particular relates to a method for increasing the length of cocoon silk after unwinding. 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] Through silk ...
