Problems solved by technology

Enzyme desizing can remove starch, does not damage fibers, and is easy to wash with water, but it has no desizing effect on other sizing and impurities, and the cost is high. At present, few enterprises use this method; alkali desizing, oxidant desizing and acid desizing Pulp is very harmful to fabrics, especially for cotton woven fabrics, because of its small elasticity, it is easy to damage

Abstract

The invention discloses desizing fluid for pretreatment of cotton woven fabric. The desizing fluid comprises, by weight, 12-25 parts of 12% hydrogen peroxide, 4.5-6 parts of argon sodium bromate, 30-50 parts of amylolytic enzyme, 15-25 parts of sodium chloride, 2-6 parts of penetrant, and 100 parts of water. Effective desizing and reduced damage of the cotton woven fabric by desizing can be achieved by organic combination of enzymes, oxidants and the like. In addition, pollution discharge can be reduced as the desizing fluid is improved.

Description

Technical field [0001] The present invention involves a degenerate solution for a fabric. Background technique [0002] Retreatment is the process of removing the slurry on the fabric.Most of the meridians of fabrics such as cotton, sticky glue, and synthetic fiber passed through the yarn before weaving.The slurry will affect the wetness of the fabric during the dyeing process and hinder the contact of chemicals to fiber.Therefore, the fabric is generally degraded first.Cotton fabrics have the effects of removing part of the impurities in the fiber; synthetic fiber fabrics can sometimes be degraded at the same time during the refined process.There are currently four categories of degraded solution: enzyme, alkali, oxidant, acid.Enzymes can remove starch, do not damage fiber, and have the advantages of easy washing, but there is no degradation effect on other pulp and impurities, and the cost is high. At present, few companies use this method.The pulp is damaged to the fabric, esp...
