Cotton type woven fabric continuous biochemical pretreatment technology

Abstract

The invention mainly discloses a cotton type woven fabric continuous biochemical pretreatment technology, relating to the technical field of composite preparation of a composite biological enzyme preparation and a composite pretreatment preparation and the application of the composite preparation in the cotton type woven fabric pretreatment technology. The technology comprises the steps of: usingthe composite biological enzyme preparation (the preparation comprises amylase, pectinase, neutral cellulose enzyme, penetrating agent JFC and stabilizing agent) to pretreat the woven fabric, therebypartially or wholly removing starch size, pectin and the other natural or artificial impurities on the woven fabric, and improving the wettability of the woven fabric; and water washing and padding the composite pretreatment liquid (the liquid comprises composite pretreatment agent, hydrogen peroxide and refined penetrating agent); and water washing with steam, wherein the whiteness, the capillary effect, the size removing rate and the strength of a product are better than the normal technology. The technology also solves the problems of high sewage alkalinity, large energy consumption and bad product quality, and the like, in a normal pretreatment technology which takes caustic soda as a main raw material.

Description

technical field

[0001] The invention is a continuous biochemical pretreatment process for cotton-type woven fabrics, which relates to the technical field of compounding of compound biological enzyme preparations and compound pre-treatment agents and their application in the pre-treatment process of cotton-type fabrics, and belongs to the field of cotton in the textile printing and dyeing industry. Type woven fabric pretreatment technology field. Background technique

[0002] The traditional continuous pretreatment of cotton fabrics adopts a three-step process: desizing→scouring→bleaching. This process takes a long time, requires a lot of water, electricity, and steam, and uses a large amount of chemicals, resulting in high COD value of wastewater, difficult sewage treatment, and does not meet the current environmental protection processing requirements. The traditional pretreatment method of cotton woven fabric is to use alkali as the main and surfactant as the supplementar...
