Abstract

The invention discloses a solid low-temperature pretreatment compound preparation, which is composed of a scourzyme preparation A and an additive B, wherein the scourzyme preparation A accounts for 20-40% by weight, and the additive B accounts for 60-80% by weight. Components of the scourzyme preparation A are 10-70% of pectate lyase, 0-50% of cutinase, 0-30% of xylanase and 0-30% of cellulose by weight. Components of the additive B are 20-40% of hydrogen peroxide activator and 60-80% of phosphate by weight. The solid low-temperature pretreatment compound preparation resolves problems of existing scourzyme, is capable of effectively removing cotton wax and cottonseed hull in fiber, stable in effect and suitable for cotton knitted fabrics of various deep colors and light colors, can be applied to enzyme oxygen one bath process, combines scouring and bleaching, simplifies technological process, does not require high-temperature treatment, lowers comprehensive cost and meets industrial policies for energy saving and consumption reducing of the country.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a solid low-temperature pretreatment compound preparation. Background technique [0002] At present, the textile industry mostly adopts the traditional pre-treatment process of printing and dyeing, relying on strong acid, strong alkali and high temperature to treat cotton and linen, which not only damages the strength of the fiber, but also causes serious environmental pollution. With the enhancement of people's awareness of environmental protection, environmental protection and energy-saving technology has become an urgent technology for printing and dyeing manufacturers. [0003] Scouring enzyme preparations are enzymes used in the printing and dyeing process of the textile industry, used in the scouring process, and play a role in biocatalytic hydrolysis. Commonly used scouring enzyme preparations include pectinase, cellulase, protease, lipase, etc. It is u...
