Embodiment Construction

[0033] The present invention will be further described below in conjunction with the examples, but not as a basis for limiting the present invention.

[0034] An enzyme preparation is a composite enzyme preparation with a pH of 6-10 comprising 3-50 g / L compound refining enzyme, 0.2-20 g / L amylase, and 1-100 g / L emulsification penetrant.

[0035] The preferred solution is: it is a composite enzyme preparation with a pH of 6-10 comprising 5-20 g / L decompounding refining enzyme, 2-5 g / L amylase, and 6-20 g / L emulsifying penetrant.

[0036] 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.

[0037] The textile is treated by using the enzyme preparation to replace the desizing, singeing and scouring processes in the pretreatment process of the textile.

[0038] The methods for treating...

Abstract

The invention discloses an enzyme preparation which is characterized by being a compound enzyme preparation with a pH value ranging from 6 to 10 and comprising 3-50g / L compound refining enzyme, 0.2-20g / L amylase and 1-100g / L emulsifiable penetrant. The application of the enzyme preparation can replace the traditional desizing and scouring processes. The invention can overcome the disadvantages of complicated procedures, high steam and electricity consumption and large sewage discharge amount in the pretreatment process of the traditional textile, can reduce the damage to the textile and the pretreatment difficulty of the cotton blended / mixed texture, decreases energy consumption and sewage, and lowers the COD (Chemical Oxygen Demand) content in the sewage.

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...
