Problems solved by technology

Although the application of enzymes in the degumming and scouring of silk and its fabrics has the above-mentioned advantages, and there are many studies on the application of proteases in degumming, enzyme scouring has not yet been applied to production. The main reasons are as follows: ①Suitable for silk and There are few enzymes for scouring silk and its fabrics. At present, there are mainly a few types of proteases that can be used for scouring silk and its fabrics, such as 2709. Therefore, more enzyme preparations suitable for scouring silk and its fabrics need to be developed
②Compared with chemical refining, the cost of enzyme refining is high. The main reason is that the price of enzyme preparations is high. It is necessary to transform enzyme-producing microorganisms through genetic engineering technology to increase enzyme production and improve enzyme production processes to reduce enzyme prices.
③ Complexity of enzyme action conditions

Abstract

The invention discloses a method for degumming raw silk and fabric thereof by recomposing papain and a reagent N, which improves, prolongs and stabilizes the enzymatic activity through enzyme recomposition, thereby improving the degumming effect of enzyme, being beneficial to controlling the process of degumming and decontaminating and reducing the working procedures. Comparing with the method only using an enzyme treated sample contrast, the decrement rate of the complex enzyme treaded sample is 1.5-2.30 times of that of the contrast; compared with the method only using a reagent N treated sample contrast, the decrement rate of the complex enzyme treaded sample is 120-185 times of that of the contrast, thereby greatly saving the enzyme reagent, reducing the degumming and refining cost and keeping the deserved strengthen of the degummed silk and the fabric thereof.

Description

technical field [0001] The invention relates to the technical field of textile industry, in particular to a degumming method for paired raw silk and its fabric compounded with papain and reagent N. Background technique [0002] Raw silk and gray silk contain a considerable amount of sericin and a small amount of oil, wax and other impurities. The existence of these substances affects the luster and feel of silk fibers, and will bring certain difficulties to subsequent processing. Remove grease, wax and most of the sericin to make the silk fiber soft, loose and clean. This is the degumming or refining of silk and its fabrics. The quality of degumming has a great influence on the quality of silk and the quality of finished products. There are many methods for scouring silk and its fabrics, including physical methods, such as high temperature and high pressure water method; chemical methods, such as: alkali method, soap alkali method, acid method; biological methods, including...
