Embodiment Construction

[0035] The present invention will be further described below in conjunction with the examples, but not as a basis for limiting the present invention.

[0036] An enzyme preparation comprising 0.5-20 g / L cottonseed hull removal enzyme, 0.2-20 g / L amylase, 0.5-10 g / L cellulase, and 1-100 g / L emulsified penetrant with a pH of 4-7 Compound enzyme preparation.

[0037] The preferred solution is: it is a compound with a pH of 4-7 containing 2-10g / L cottonseed hull removal enzyme, 2-5g / L amylase, 0.5-3g / L cellulase, and 6-20g / L emulsified penetrant Enzyme.

[0038] 0.5-10 grams of Tween 80 and 0.5-10 grams of sodium tripolyphosphate are added per kilogram of the enzyme preparation. Also add 1 gram of Tween 80 and 1 gram of sodium tripolyphosphate per kilogram of the enzyme preparation, which is more optimal.

[0039] The textile is treated by using the enzyme preparation to replace the desizing, singeing and scouring processes in the pretreatment process of the textile.

Abstract

The invention discloses an enzyme preparation. The enzyme preparation is characterized in that: one liter of the enzyme preparation comprises 0.5 to 20g of cotton seed hull removal enzyme, 0.2 to 20g of amylase, 0.5 to 10g of cellulose, and 1 to 100g of complex enzyme preparation of emulsifiable penetrant, wherein the pH of the complex enzyme preparation is 4 to 7. By applying the enzyme preparation, the conventional desizing and scouring process can be replaced. The defects of complex steps, high steam consumption, and electric power and sewage discharge value in the conventional fabric pretreatment processing are overcome, the damage to the fabric is reduced, the processing difficulty of pretreatment on cotton blend fabric and mixed fabric is reduced, and energy consumption, sewage and the chemical oxygen demand (COD) content in the sewage can be reduced.

Description

technical field [0001] The invention relates to an enzyme preparation and its application, especially the application in textile pretreatment process. Background technique [0002] Now the traditional pretreatment processing process is mostly: desizing (including enzyme desizing, alkali desizing) → singeing → alkali scouring (alkaline-oxygen cold stack), the additives used are amylase, caustic soda, Refining agent, penetrating agent, etc., mainly use amylase to biodegrade starch, caustic soda, refining agent scouring to decompose and degrade cottonseed hulls, lignin, cotton wax, and then remove residual lignin, cottonseed hulls, wax and wax by bleaching Pigment, singeing is to use natural gas or gasoline as the burning material to remove the lint on the surface of the cloth. The traditional desizing process consumes a lot of steam. The average COD content of water, electricity, and waste water reaches about 20,000ppm. Scouring also consumes a lot of steam. , water, electric...
