Embodiment Construction

[0013] The degumming and bleaching treatment of cocoon silk of the present invention is realized in this way, and it is carried out in a steam tank with a capacity of 50 kg of silkworm cocoons at a time, and 50 kg of water, 1.5 kg of sodium carbonate, 1.2 kg of sodium silicate, and 0.2 kg of mercerized soap are mixed. Stir evenly to make a degumming solution; put 50kg silkworm cocoons into the degumming solution and soak them, add steam from the bottom of the tank and steam for 20 minutes; remove the cocoons and deliquify them in a centrifuge, and rinse the degummed cocoons in a clear water pool for 5 minutes Minutes, fish out the rinsed cocoons and centrifuge for dehydration.

[0014] Take 50kg of water, 0.5kg of sodium carbonate, 0.5kg of sodium silicate, 0.5kg of sodium hydroxide, and 25kg of hydrogen peroxide with a concentration of 27% to make a bleaching solution; place the bleaching solution in a steam tank and put it into dehydrated cocoons Add steam from the bottom of...

Abstract

The present invention belongs to the field of silkworm cocoon silk reeling off method in filature, and is one kind of silkworm cocoon degumming and bleaching process. The technological process includes the successive steps of: compounding degumming liquid, soaking silkworm cocoon and steaming with water vapor for 20 min, eliminating liquid, rinsing with clear water, dewatering, compounding bleaching liquid, soaking silkworm cocoon and steaming with water vapor for 40 min, eliminating liquid, rinsing with clear water, dewatering, compounding silk protecting liquid, swinging and washing for 30 min, eliminating liquid and stoving. The silkworm cocoon degumming and bleaching process has greatly shortened degumming time from traditional 24 hr to 20 min, homogeneous bleaching and few silk corrosion, and the silk treated with the silk protecting liquid is bright, smooth and without silkworm cocoon smell.

Description

technical field [0001] The invention belongs to the technical method of cocoon spinning in the silk reeling industry, and relates to a cocoon silk degumming and bleaching process. Background technique [0002] In China, for many years silkworm cocoons have been drawn by using alkali water boiling degumming-hydrogen peroxide bleaching process. Due to the high concentration of alkali in this process, it takes 24 hours to process cocoon silk in alkali solution, which not only reduces production efficiency, but also affects cocoon with alkali solution. The erosion of silk is serious, which affects the performance and use effect of cocoon silk. Contents of the invention [0003] The present invention overcomes the above-mentioned defects. The purpose of the present invention is to use degumming solution, bleaching solution and protective solution instead of soda ash and hydrogen peroxide solution to treat silkworm cocoons in the silkworm cocoon spinning process, so as to reduce...
