Problems solved by technology

[0003] The present invention aims at the existing problems: the traditional degumming method, the boiling water method has high temperature and takes a long time, and the high temperature is likely to cause denaturation of the silk fibroin part; while the soap boiling method has high requirements on the purity of the soap, the degumming efficiency is low, and the time is long. - The tartaric acid method has low temperature and high degumming efficiency, but tartar

Abstract

The invention discloses an efficient and environmentally friendly silk degumming method. The method comprises (1) silk drying: drying silk at a temperature of 40-44 DEG C until moisture content of 22% to 25% to obtain dried silk, (2) degumming: adding an enzyme, mixed extract, mixed plant oil and sodium chloride into a degumming tank and carrying out silk degumming treatment, (3) water washing: immersing the silk subjected to crude degumming in clear water and carrying out washing for 10-13min, and (4) washing: adding 10% to 13% of a functional detergent into water in drum equipment and carrying out washing at 28-32 DEG C at a rotation rate of 95-107 r/min to obtain degummed silk.

Description

technical field [0001] The invention belongs to the technical field of silk processing, and in particular relates to an efficient and environment-friendly silk degumming method. Background technique [0002] Silk is mainly composed of silk fibroin and sericin protein wrapped outside, which accounts for about 97% of silk, and sericin accounts for more than a quarter of silk. In the degumming process of silk, sericin is mainly removed. The silk fibroin part after degumming is the subject of silk processing. The process of silk degumming is divided into two parts, the first is the swelling and denaturation of sericin protein, and then the process of the molecules of sericin protein being dispersed or dissolved in water. Due to the complex amino acid composition of sericin, sericin is divided into easily soluble and insoluble parts according to its dissolution sequence. , the geometric position of the amino acid, etc.), and is related to the degumming agent used. Commonly use...
