Method for preparing anti-wrinkle regenerated silk by using defective silkworm cocoons

Abstract

The invention discloses a method for preparing anti-wrinkle regenerated silk by using defective silkworm cocoons. The method includes the steps of 1), taking out silkworm pupae treated with micropowder and a hypochlorite solution prior to putting into the air; 2), performing degradation of cocoon powder by adopting high pressure cooking, enzymatic hydrolysis of mixed enzyme, a sodium hydroxide solution and a wall breaker by means of stirring; 3), adding an emulsifying modifier and a functional agent to a silkworm cocoon dissolving solution, and respectively performing high speed stirring and constant temperature and constant pressure reaction; 4), mixing polyacrylamide and polytene with acrylic hydroxyacetic acid for ammonia treatment, and then adding a silk modified degradation solution, zinc acetate and monometallic sodium orthophosphate by stirring and mixing for reaction; 5), drying and cooling a mixed solution to form colloidal, and preparing regenerated silk through mold spinning holes; 6), treating the newly spun regenerated silk by using a finishing solution to obtain the spinning regenerated silk.

Description

technical field [0001] The invention belongs to the technical field of silkworm cocoon processing, and in particular relates to a method for making wrinkle-resistant regenerated silk from defective silkworm cocoons. Background technique [0002] Silk is a natural fiber that is coagulated from the silk liquid secreted by mature silkworms. Silk quilts and textile fabrics made of silk have smooth hand feeling, low irritation, high air permeability, comfortable and refreshing wearing, and have high application value and economy. value, and has high environmental protection and health attributes. Silk is mainly composed of external sericin protein and internal fibrous silk fibroin. Through drying, selection, cocoon cooking, silk reeling and other processing of silkworm cocoons, silk fibroin and sericin are separated to form silk, and silk is woven into various silk products. A high-grade fabric for garment processing. In the cocoon selection process of silkworm cocoons, a large...

Problems solved by technology

In the cocoon selection process of silkworm cocoons, a large number of defective cocoons that are not suitable for processing will be selected, such as double palace cocoons, piercing cocoons, macular cocoons, purple printed cocoons and thin skin cocoons, mainly due to the influence of external factors during silk spinning. Or the influence of its own factors, resulting in the poor quality of the cocoons formed, which is not conducive to later processing and use, and a large part of the selected defective cocoons are discarded, resulting in a waste of resources; and although the fabrics processed by silk have relatively high Good hand feeling, smoothness and comfort, but its anti-wrinkle performance is poor, long-term wearing and folding will cause silk wrinkling, affecting the quality and aesthetics of wearing
