Leather ProcessingPosted by King Winny on April 13th, 2019 (1) DegreasingLipase enzymes used in leather industry has achieved good results in degreasing of crepe, fur, leather, gelatin, and the like. Candida lipolytica lipase can reduce the oil content of the raw material of the spinning material from 10% to 0.5%, to meet the spinning requirements, and does not affect the fiber strength. Lipase can also remove fat between leather collagen fibers and degrease for fur. It not only has the advantage of not affecting the thickness and fastness of the leather, it can also make the fur product full, soft and elastic. After lipase treatment, the small droplets in the gelatin solution can be removed, and the oil stains on the instrument rag and the optical components can be removed to improve the quality and cleanliness of the product. (2) Preparation of chemical products and reagentsBy utilizing the action properties of lipase hydrolysis, synthesis and trans-fatty acid, it is possible to prepare chemical products with high chemical production costs. Erucic acid and its derivatives have a wide range of chemical applications and can be used in petrochemical, textile, chemical, light, and plastic industries. Like it? Share it!More by this author |
