Problems solved by technology

Alkali degumming is easy to damage silk fibroin and reduce the strength and elongation of silk fibers; acid degumming is not easy to control, the cost is high, and there is a volatile irritating smell in production, which can damage skin, clothes and equipment, and is rarely used in production.
The enzymatic degumming method is superior to the traditional acid and

Abstract

The invention discloses a treatment process for degumming and bleaching silk. The treatment process comprises the following steps: carrying out pretreatment, namely firstly putting the silk into a closed container, introducing 20-50g/L active oxygen for carrying out the pretreatment on the silk; and then carrying out treatment of primary refining, secondary refining, bleaching, washing with water, and shaping. The treatment process disclosed by the invention has the beneficial effects that at the pretreatment stage, the silk is put in the closed container, the 20-50g/L active oxygen is introduced for carrying out the pretreatment on the silk, macromolecular chains of silk glue can be broken, and a silk-glue layer is cracked and loose, so that the permeation and the action of primary-refining liquid and secondary-refining liquid in the next procedure are accelerated, the action time is reduced, and the used amount of the primary-refining liquid and the secondary-refining liquid is reduced. The treatment process disclosed by the invention has the advantages that a water resource is saved, the used amount of chemicals is reduced, and the environment pollution is reduced.

Description

technical field [0001] The invention belongs to the dyeing and finishing process in the textile industry, in particular to the degumming and bleaching process of silk. Background technique [0002] Silk is the fiber that solidifies after the silk liquid in the silkworm body is spouted out, and is called cocoon silk. It is composed of two silk proteins (also known as silk fibroin) with a nearly triangular or semi-elliptical cross-section wrapped in sericin, as well as pigments, oil waxes and inorganic substances, which are present in the sericin. Among them, sericin has a certain protective effect on silk fibroin, but if the content is too much, it will affect the luster and feel of silk fibroin and the process of silk fiber processing, while impurities such as oil and wax will bring certain difficulties to post-processing. . Therefore, before dyeing and finishing, most of the sericin, grease, wax and other sundries must be removed to make the silk fiber soft, loose and cle...
