Problems solved by technology

[0005] At present, the biological enzyme scouring pretreatment of cotton fabrics is mainly based on the combination of alkaline pectinase, cellulase, and amylase. The problem is that cotton seed hulls cannot be effectively removed, and it cannot assist in bleaching, reducing the amount of subsequent hydrogen peroxide bleaching. ,high cost

Embodiment Construction

[0017] The equipment used in the present invention is a stirring tank. As a preferred embodiment, the stirring tank is a DSH-20 double helix asymmetric stainless steel stirring tank. Its suitable working state is: revolution speed is 1 circle / min, rotation speed is 62 circle / min, stirring at room temperature, total feeding volume ≤1.2 tons.

[0018] Taking the production of one ton of scouring and bleaching compound enzyme as an example, the production process is as follows:

[0019] First of all, the raw material configuration list is arranged according to the dosage of producing one ton of scouring and bleaching complex enzyme.

[0020] Next, accurately weigh 300 kg of a-amylase, 300 kg of pectinase, 100 kg of xylanase, 200 kg of laccase, and 100 kg of cellulase according to the raw material configuration sheet.

[0021] Among them, the proportion of a-amylase with an enzyme activity of 3000IU / g should be 20-30%, the proportion of pectinase with an enzyme activity of 5000IU / g should...

Abstract

The invention provides a process for manufacturing an energy-saving and environment-friendly cooking and bleaching compound enzyme preparation for weaving and belongs to the field of bio-enzyme products. The compound enzyme mainly comprises an alpha amylase, a pectinase, a xylanase, a laccase and a cellulase. The process of the invention uses the enzyme preparation capable of degrading hemicelluloses and lignins for pretreating natural fibers and textiles, can effectively degrade fiber containing impurities such as pectins, hemicelluloses and lignins, is easy to clean, and can reduce washing times, sewage discharge and COD value (chemical oxygen demand), effectively assist a bleaching process and decrease the dosage of a hydrogen peroxide solution.

Description

Technical field [0001] The invention belongs to the field of biological enzyme products. Background technique [0002] Cotton textile materials have many consumers due to their unique characteristics of moisture absorption, ventilation, and warmth. According to statistics, the value of cotton fiber used in textiles worldwide can reach 42 billion pounds every year. However, due to the accompanying organisms of the cotton fiber itself and the impurities added in the spinning and weaving process of the cotton fiber, which affect its wetting performance, the cotton fabric generally needs to be pre-treated. [0003] The traditional pre-treatment process is a process of intense chemical reaction, which has a long process route, high energy consumption, and serious pollution. This contradicts the increasing environmental protection requirements and "green production", so new processes and new technologies are emerging in endlessly. The enzymatic scouring technology of fabrics came into ...
