Abstract

The invention discloses a pre-treatment auxiliary agent for cotton knitted fabrics, a preparation method and application thereof, belonging to the technical field of pre-treatment process formulas of the cotton knitted fabric dyeing and finishing industry. The auxiliary agent comprises the following components in percentage by weight: 40-65 percent of alkali agent, 5-10 percent of tea saponin, 0.3-3 percent of hydrogen peroxide stabilizer SOF, 1-10 percent of wetting penetrating agent, 2-5 percent of hydrogen peroxide activating agent and 20-40 percent of anhydrous sodium sulphate. By applying the auxiliary agent, the whiteness and capillary standards of the traditional process can be achieved only by using the auxiliary agent with hydrogen peroxide. The invention has the advantages of simple operation, low production cost, good environmental protection, and the like.

Description

Technical field: [0001] The invention relates to a pretreatment auxiliary agent for cotton knitted fabrics, a preparation method and an application thereof, and belongs to the technical field of pretreatment process formulations in the dyeing and finishing industry of cotton knitted fabrics. Background technique: [0002] The natural cotton fabric is yellow in color and poor in water absorption, but from the chemical structure of cotton fiber, it should have good water absorption. The main reason for this contradiction is that the fiber contains 90% of Cellulose, also contains about 10% natural impurities (also known as cellulose co-growth). These natural impurities mainly include pectin substances, proteins, waxy substances, natural pigments, etc. In addition, a small amount of cottonseed hull fragments will also be entrained when the cotton fibers are stripped. These natural impurities have seriously affected the excellent wearability of cotton knitted fabrics. [0003] ...
