Biopolishing enzyme

After more than a century of research by scientists, more than 3,000 biological enzyme preparations have been recognized. At present, the most widely used enzyme preparations in textile printing and dyeing are mainly cellulase, protease, amylase, pectinase, lipase, Eight types of peroxidase, laccase, and glucose oxidase:

Cellulase
Cellulose is a multi-component enzyme system composed of various enzymes with different catalytic properties. It is generally believed that cellulase is mainly composed of CBI I, CBH II and glucosidase, and these enzymes have a synergistic effect in the process of cellulose hydrolysis.

pectinase
Pectinase is mainly composed of pectin lyase, pectin esterase, polygalacturonase and pectate lyase.

Lipase
Lipase can hydrolyze fat into glycerol and fatty acid, and fatty acid can be further oxidized to synthesize sugar

catalase, protease
Catalase is a redox enzyme that catalyzes the decomposition of hydrogen peroxide to produce water and oxygen.
The proteases secreted by microorganisms vary greatly due to the different strains used, but they are generally the same, that is, the protease decomposes proteins into peptides, and the peptides are hydrolyzed to generate amino acids.

amylase
Amylase is a general term for enzymes that hydrolyze starch and glycogen. Usually, amylase catalyzes the hydrolysis of starch slurry on fabrics. Due to the high efficiency and specificity of amylase, enzyme desizing has high desizing rate and fast desizing. Less pollution, the product is softer than the acid method and subtraction method, and does not damage the fiber.

Laccase, Glucose Oxidase
Laccase is a kind of oxidoreductase. Denilit II S of Novozymes is a genetically modified Aspergillus niger laccase, which can be used for the finishing process of denim clothing. Glucose oxidase is mainly used for bleaching and finishing of fabrics. This enzyme treatment is very effective for the production of hydrogen peroxide. The treatment makes it unnecessary to add hydrogen peroxide stabilizer, and the fabric feels soft and plump after treatment.
