Problems solved by technology

[0006] In order to solve the above-mentioned problems such as the loss of pigment damage during the degumming process of colored silk, or the slight degumming in order to retain the pigment, which will cause the subsequent fabrics to feel stiff and difficult to weave, one of the purposes of the present invention is to provide a composite material for degumming and color fixing of natural colored silk. Enzyme, the composite enzyme has a scientific and reasonable composition formula, and has good degumming and color-fixing properties. The second purpose of the present invention is to provide a method for using a composite enzyme for natural colored silk degumming and color-fixing. The method is easy to operate, economical and practical

Abstract

The invention relates to the technical field of natural colored silk processing, in particular to a complex enzyme for degumming and fixation of natural colored silk and an application method of the complex enzyme. The complex enzyme comprises a bio-enzyme A and a bio-enzyme B; the bio-enzyme A comprises, by weight, 1-10% of papain, 1-10% of bromelain, 0.5-5% of neutral protease, and 0.1-3% of lipase; the bio-enzyme B comprises, by weight, 1-10% of sulfhydryl oxidase and 0.3-5% of protein disulfide isomerase. With the complex enzyme and the application thereof, the biggest obstacle in promotion and application of colored cocoons in the later period is omitted, the pure-natural style of colored silk is guaranteed, the dyeing and finishing process is omitted, and the high-quality environmental protection concept is met.

Description

technical field [0001] The invention relates to the technical field of natural colored silk processing, in particular to a compound enzyme for degumming and color-fixing natural colored silk and a use method thereof. Background technique [0002] Natural colored mulberry silk is a silk protein fiber with natural color. Its cocoon silk has soft and bright color, and has excellent properties such as antibacterial, anti-oxidation, and anti-ultraviolet. It is suitable for weaving underwear, infants and other clothing. The color of natural colored silk mainly comes from the pigment substances in cocoon silk sericin, such as carotenoids and flavonoid pigments. The structure of these pigments is unstable, and degumming will completely lose the color. The hand feel is not good, and there is a tingling feeling, which is not conducive to the production and utilization of colored silk. [0003] Sericin is a kind of globular protein, its conformation is mainly random coil, and some ser...
