Abstract

The invention discloses an enzyme auxiliary agent used in a cotton linen and linen rayon gray fabric oxygen bleaching process, which is prepared by the following raw materials by weight percent: 47-60% of pentahydrate sodium metasilicate, 5-10% of alkaline pectinase, 27-30% of sodium carbonate, 5-8% of nonionic surfactant and 3-5% of chelated dispersing agent. The invention also discloses a preparation method thereof. The auxiliary agent prepared by the invention has the characteristics of effectively removing cottonseed hulls, hemp husks, impurities, natural pigment and the like, smoothing fabric surface, improving natural whiteness, and having soft and gentle feel, good appearance surface, low cost, small energy consumption, safety and environment protection.

Description

technical field [0001] The invention relates to an enzyme auxiliary used in the oxygen bleaching process of cotton flax and sticky flax gray cloth and a preparation method thereof. Background technique [0002] In the traditional pretreatment process of cotton linen and sticky linen gray cloth, oxygen bleaching is often required. The traditional oxygen bleaching process requires a large amount of chemical additives, such as caustic soda, penetrating agent, refining agent, oxygen bleaching stabilizer, chelating agent, etc. Various additives such as dispersants. It will produce a large amount of sewage and pollute the environment; and the ability to remove cottonseed hulls, hemp husks, impurities, natural pigments, etc. is weak, so that the surface finish of the cloth is not enough, the natural whiteness is not enough, the softness of the hand is poor, and the cost of chemical additives is high. , the disadvantage of not being environmentally friendly. Therefore, it is the k...
