Embodiment 1

[0018] Add cocoons and permeate in a mass ratio of 1:10 to the vacuum osmosis device. The permeate is prepared by mixing relaxing agent and distilled water at a mass ratio of 1.5:100. The pH of the permeate is adjusted to 8.0. The temperature of the vacuum infiltration treatment is 40°C and the vacuum degree is 0.08Mpa. The vacuum infiltration device is equipped with an ultrasonic emitting component below the liquid surface of the permeate. During the vacuum infiltration treatment, the ultrasonic transmitting component emits ultrasonic waves to the permeate. The ultrasonic frequency is 40KHZ, and the ultrasonic frequency is 800W. The time of vacuum infiltration treatment is 3min; The reliever used is the hydrogen peroxide of 20 weight parts, the polyacrylamide of 5 weight parts, 1 weight part of borax, the isomerism tridecanol polyoxyethylene ether phosphate of 6 weight parts, 2 It is prepared by mixing octylphenol polyoxyethylene ether in parts by weight, polyethylene emulsio...

Abstract

The invention discloses a method for increasing the reelability percentage of raw silk. The method comprises the steps of conducting vacuum penetrating treatment and upper-trough immersion treatment on silkworm cocoons, wherein vacuum penetrating treatment is completed in a vacuum penetrating device, the cocoons and penetrating fluid of which the mass ratio is 1:10-15 are added to the vacuum penetrating device, the penetrating fluid is prepared by mixing a reelability agent and distilled water of which the mass ratio is 1.2-1.5;100, vacuum penetrating treatment is conducted under the conditions that the temperature is 35 DEG C-40 DEG C and the vacuum degree is 0.08 Mpa-0.09 Mpa, the vacuum penetrating device is provided an ultrasonic emission assembly below the fluid level of the penetrating fluid, the ultrasonic emission assembly emits ultrasonic waves to the penetrating fluid during vacuum penetrating treatment, and time for vacuum penetrating treatment ranges from 3 min to 3.5 min. By the adoption of the method for increasing the reelability percentage of the raw silk, the cocoon cooking effect can be effectively improved, it is measured that the average reelability percentage can reach 77.8% after silk reeling, and the average length of non-broken cocoon filaments can reach 854 m.

Description

technical field [0001] The invention relates to the field of textile production, in particular to a method for improving the unwinding rate of raw silk. Background technique [0002] Silk is obtained by weaving real silk, and real silk is processed by reeling silkworm cocoons and boiling cocoons. The silk reeling and cocoon cooking process mainly includes cocoon mixing, cocoon peeling, cocoon selection, cocoon cooking, silk reeling, reshaking, and finishing. Among them, the cocoon cooking process is to make use of water, heat or chemical additives to make the cocoon silk glue point sericin properly swell and soften, reduce the adhesive force between the cocoon silk, and make the cocoon silk dissociate sequentially to meet the requirements of reeling. silk production requirements. Different cocoon cooking techniques and technical measures are used in silk reeling production, which have a great impact on the quality of reeled silk. Only when cocoons are cooked well can silk ...
