Problems solved by technology

[0006] Although the biological enzyme pretreatment of cotton fabrics has been studied for many years, due to the limited selection of several biological enzymes, no further discussion has been made on the mutual synergy or inhibition of various biological enzyme preparations. Therefore, the currently used Enzyme desizing, enzyme scouring, and then bleaching process route, the treatment effect is not good, the hydrophobic substances cannot be removed fundamentally, and the wettability still cannot meet the requirements of subsequent production

Abstract

The invention refers to a kind of process for cotton textile starch enzyme, pectinase, cellulose enzyme continuous desizing, refinement prepreocess, it belongs to textile front process field in printing and dyeing industry. It solves the technology problem that the effect of cotton textile biology enzyme continuous steam front process is not good, and it optimizes the process effect. The invention uses three-steps method front process of carry on cotton textile impregnating desizing enzyme liquid, steaming and washing with water, then carry on impregnating biology refinery liquid, steaming, enzyme eliminating, water washing, finally carry on impregnating hydrogen peroxide solution bleaching liquid, steaming and washing with water. The effect is good, the harm does to the fiber is small, the quality of textile is high, the product is soft, the method process the colourity, pH value, COD value to degree far lower than the current process, it reduces the bear of waste water processing, it is advantage to protect the environment, the efficiency is high, the low labour intensity, energy saving, and water saving.

Description

Technical field [0001] The invention relates to a continuous desizing and scouring pretreatment process for all cotton woven fabrics with amylase, pectinase, and cellulase, and belongs to the technical field of pretreatment processes for all cotton woven fabrics in the printing and dyeing industry. Background technique [0002] In order to meet the requirements of normal weaving process, all cotton warp yarns generally need sizing process, and the cotton fiber contains 0.4-1.2% pectin, 0.4-1.2% wax, 1.0-1.9% protein, 0.7-1.6 % Of natural impurities such as ash or companion organisms, these impurities mainly exist in the stratum corneum and primary cell walls of cotton fibers. The presence of size and impurities seriously affects the wettability of cotton fabrics, makes cotton fabrics hydrophobic, and affects the dyeing and finishing properties of cotton fabrics. Therefore, the first step in the dyeing and finishing of cotton textile products is to carry out pre-treatment to remov...
