Problems solved by technology

However, since the enzymes produced by enzyme preparation manufacturers mainly refer to proteases, and are not proteases for wool scales, the effect of this enzyme on wool scales is not ideal, and the wool keratin stripping of wool scales cannot be effectively completed.

[0016] Wool Example 1: Preparation of Compound Enzymes

[0017] Composite enzyme producing bacteria—→Culture on slant, add 0.5% wool powder to the medium—→Pick out high-incidence strains after cultivation—→Fermentation culture medium: 5% soybean flour, 1.0% corn flour, 1.0% fish meal, CaCL20 .5%, NH4CL 0.5%, Na2HPO4 1.0%, wool powder 0.5%, and the rest is water, at a temperature of 30°C and a shaker speed of 200 rpm, shaking culture for 88 hours—→fermentation broth coarse filtration—→filtrate separation , at 3000 rev / min, 10 minutes—→get compound enzyme liquid.

[0018] The composite enzyme prepared according to the above method is used for scale removal and post-finishing, such as taking a woolen sweater sample——→pretreatment, that is, 30% concentration of H 2 o 2 30ml / L, Na 2 CO 3 0.2%, Na 2 SO 3 0.7%, JFC 3%, bath ratio 1:25, treatment at 50°C for 35-40 minutes—→add H2O2 compound enzyme to remove excess H2O2—→water washing—→dehydration—→compound enzyme treatment: P...

Abstract

The invention involves the preparation method of the compound enzyme tidy up wool fabric which is made through slant culture, fermentation, shocking culture and filtering. Because the enzyme is a kind of biological enzyme preparation, so the wool sweater after being scaled will not contain AOX. As it has good specifity to wool protein, so the wool reduction quantity is just 1-2.5% which basically not influence the intensity and thickness of the wool sweater. Using the compound enzyme to scale under pH=3.0-5.0 acid conditions, the wool sweater will not fade and become yellow.

Description

technical field [0001] The invention relates to a preparation method of a composite enzyme for finishing wool fabrics. Background technique [0002] As we all know, the finishing of wool fabrics, such as: anti-shrinkage, softness, mercerizing, etc., is the last processing link in the production of wool fabrics. Through this link, the woolen fabric can obtain excellent clothing performance and increase the added value of its products. [0003] Wool is a natural protein fiber with a layer of scales on its surface. They overlap and cover the hair shaft like fish scales or tiles. With a very thin lipid layer. [0004] The use of biological enzymes to replace chlorinated scales has been favored by many researchers and sweater manufacturers in recent years because it conforms to the development trend of green finishing. But because the enzyme produced by the present enzyme production enterprise mainly refers to protease, and is not for the protease of wool sc...
