Application of Enzymes in Textile


Application of Enzymes in Textile


Cellulase (β-1,4-glucan-4-glucan hydrolase) is a generic term for a group of enzymes that degrade cellulose to produce glucose. It is not a monomeric enzyme, but a synergistic multi-component enzyme system. It is a complex enzyme consisting mainly of exo-β-glucanase, endo-β-glucanase and β-glucosidase, as well as highly active xylanase. It is a product that acts on cellulose and is derived from cellulose. Cellulase is commonly known as hair removal agent, polishing enzyme, hair removal agent, hair consuming agent, and the like.

2. Pectinase

Pectinase is also a type of complex enzyme, which is a general term for various enzymes that decompose pectin. Pectinase is mainly composed of pectin lyase, pectin esterase, polygalacturonase and pectate lyase. Pectinase is now mainly used in the pretreatment of cotton and hemp fiber, and is compounded with other enzymes, called scouring enzyme.

3. Lipase

Lipases hydrolyze fats to glycerol and fatty acids, which can be further oxidized to synthesize sugars.Lipase is mainly used in the textile industry for degreasing and improving properties of textile raw materials. Lipase is mainly used to treat wool fibers, remove some of the lipids in the wool, cause physical and chemical changes in the wool fibers, and improve the quality of the wool.

4. Catalase

Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide into oxygen and water and is present in the peroxisomes of cells. Catalase is a peroxidase-labeled enzyme that accounts for about 40% of the total peroxidase enzyme. Catalase is present in various tissues of all known animals, particularly in the liver at high concentrations.Catalase is commonly known in the printing and dyeing industry as deoxygenase, deoxygenase, and deoxygenase. There are two main types of use: animal liver catalase and plant catalase. The latter has better performance!

5. Amylase

Amylase is a generic term for enzymes that hydrolyze starch and glycogen, and is typically catalyzed by amylase to hydrolyze starch slurries on fabrics. Due to the high efficiency and specificity of amylase, the desizing rate of enzyme desizing is high, the desizing is fast, and the pollution is less. The product is softer than the acid or alkali method and does not damage the fiber.Amylase is commonly known as desizing enzyme in the printing and dyeing industry. According to the different use temperature, it is divided into normal temperature desizing enzyme, medium temperature desizing enzyme, high temperature desizing enzyme, broad temperature desizing enzyme and so on.

6. Laccase / glucose oxidase

Laccase is an oxidoreductase that can be used to perform distressed finishing of denim garments by genetically modified Aspergillus niger laccase. The obtained fabric has a thick hand, a smooth surface, a bright color and a light color. Glucose oxidase mainly performs bleaching of fabrics. This enzyme treatment is very effective for the production of hydrogen peroxide, and the treatment does not require the addition of a hydrogen peroxide stabilizer, and the treated fabric is soft and full.
