A kind of pretreatment process of silk floss

Abstract

The invention relates to the technical field of textiles, and specifically relates to a pretreatment process for silk floss. The pretreatment process for silk floss comprises a refining and bleaching process flow and a neutralizing and softening process flow, and is characterized by comprising the following specific steps: refining and bleaching; neutralizing and softening. Compared with the prior art, the pretreatment process has the advantages that an integrated working system of a biotechnology and a chemical technology is adopted, a new process path is designed, use of chemical aids is reduced on the basis of one-step refining and bleaching, the treatment temperature is reduced, the treatment time is shortened, the consumption of energy including water, electricity, gas and the like is greatly reduced, the discharge of waste water is reduced, the yield and the product quality are effectively improved, and clean production, energy conservation and emission reduction are really realized.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a pretreatment process of silk floss. Background technique [0002] Silk floss is made from the floating silk on the surface of leftover cocoons and cocoon shells (including chrysalis lining cotton, double palace cotton, etc.), after refining, dissolving sericin, and loosening the fibers. It has good warmth retention property and can be used as cotton wool and quilt. The scouring and bleaching process of silk floss in the traditional craft includes two processes of degumming and bleaching. Degumming and bleaching are completed in two independent processes, so the process is complicated, the equipment assembly line is long, and the energy consumption is large; the operation time is long, the silk is damaged, and the production efficiency is low; the working fluid contains a large amount of alkali and bleaching agent. , silk off, etc., the discharged wastewater has serious envir...

AI Technical Summary

Problems solved by technology

Degumming and bleaching are completed in two independent processes, so the process is complicated, the equipment assembly line is long, and the energy consumption is large; the operation time is long, the silk is damaged, and the production efficiency is low; the working fluid contains a large amount of alkali and bleaching agent. , silk off, etc., the discharged wastewater has serious environmental pollution and is difficult to treat

[0003] Although in the prior art there is a process that combines the two processes of degumming and bleaching into one step, but there are many chemical additives used, the pollution of the discharged wastewater is serious, and the removal effect of impurities and grease in the silk floss after treatment is not ideal. The loss of silk floss is large, the fiber is seriously damaged, the color of silk floss is yellowish, and the softness is low, so there are not many factories that are actually used now.

[0004] For example: the published invention patent "a method for manufacturing silk quilt lining pupae" (application number 201410585989.7), in the above invention, the working liquid is put into the scouring agent according to the bath ratio of 1:25~30, Maintain a slight boiling state at 97°C~99°C for 110~160 minutes, wherein the scouring agent is composed of the following components expressed in weight percent: 0.1%~0.2% Na2CO3, 0.3%~0.5% water glass, 0.32%~0.48% fatty alcohol polyoxyethylene ether, 0.08%~0.12% alkylphenol ethylene oxide condensate and water, the composition is complex, the processing time is long, the silk loss is large, the fiber is seriously damaged, and the processing General effect
