Abstract

The invention discloses a preparation method of desizing and scouring compound enzyme. The prepared desizing and scouring compound enzyme effectively removes starch size and pectin on cotton fiber andother impurities on the surface of cotton fiber that influence dyeing property, and endows fabrics with good wetability. The desizing and scouring compound enzyme can simultaneously complete desizingand scouring by one step. Thus, processing procedures of dyeing factories is reduced, production efficiency is raised, and production cost is lowered. Process innovation is realized, and current production process can be changed. In addition, traditional high-temperature soda boiling is avoided, discharge amount of wastewater is reduced, and energy conservation, water conservation and emission reduction are realized, thus meeting the energy conservation and emission reduction requirements for green printing and dyeing. The desizing and scouring compound enzyme can meet requirements of pretreatment of dyeing factories, also can make the process to be energy-saving and environmentally-friendly, and is an ideal choice for pretreatment processing of dyeing factories.

Description

technical field [0001] The invention relates to a compound enzyme in the field of textile printing and dyeing, in particular to a compound enzyme capable of both desizing and scouring. Background technique [0002] The traditional pretreatment process of cotton fabric generally needs to go through three processes of desizing, scouring and bleaching. In the traditional process, the desizing and scouring of cotton fabrics are carried out in two steps. The quality of desizing and scouring effects has an important impact on the final dyeing and finishing effect of cotton fabrics. [0003] The size on the cotton fabric is unfavorable to the printing and dyeing process, because the existence of these sizes will contaminate the finishing fluid, consume the dyeing material, and even hinder the contact between the dyeing material and the fiber, affecting the quality of the printing and dyeing product. Therefore, at the beginning of the dyeing and finishing process, the fabric must u...
