Abstract

The present invention relates to re-compounding and application in cotton fabric treatment of enzyme preparation, and is especially enzyme process for desizing, boiling off and bleaching cotton fabric. Different enzyme preparation is first re-compounded with alpha-amylase, PVA degrading enzyme, lipase, proteinase, alkaline pectase, xylanase, cellulase, sugar oxidase, etc based on different fabric pre-treating requirements; and then used in desizing, boiling off and bleaching cotton fabric to replace traditional concentrated alkali solution and high temperature chemical process. The present invention has low power consumption and environment friendship.

Description

technical field [0001] The invention discloses a method for desizing, scouring and bleaching cotton fabrics using enzymes, and relates to the technical field of compounding of various enzyme preparations and their application in cotton fabric pretreatment processes. Background technique [0002] Traditional cotton fabric desizing, scouring, and bleaching processes are usually high temperature, high alkali, high energy consumption, and are not environmentally friendly. Using enzymes to desizing, scouring and bleaching cotton fabrics, the treatment conditions are mild, the damage to the fabrics is small, energy saving and environmental friendly. The pretreatment of cotton fabrics is all carried out by enzymatic method, using the optimal compound enzyme preparation, and realizing the optimization of process conditions, which is a topic of practical significance that is closely related to the actual production and oriented to productivity. Contents of the invention [0003] T...
