Problems solved by technology

[0004] Because the scope of application of the above-mentioned desizing method is relatively narrow and there are many shortcomings, the alkali-oxygen one-bath desizing method is currently the main method in industrial production. This is because the main advantages of this method are low cost and helpful The removal of cottonseed hulls and some fiber symbionts reduces the burden of scouring, and the whiteness and permeability of semi-finished products after treatment are good; and it is applicable to all kinds of pulp
However, there is a problem of low desizing rate using this method, which can only reach 50%~70%

Abstract

The invention provides a desizing method of fabric, and the desizing method comprises following steps that (a) plasma treatment is conducted on the fabric to be processed; and (b) desizing treatment is conducted on the fabric obtained in the step (a). Plasma treatment on the fabric is carried out before the desizing treatment is conducted on the fabric to be processed, high-energy particles in the plasma can produce an etching effect on the surface of the textile fabric, so that a continuous coverage state of fiber spreading mass and waxiness is oxidized and destructed, molecular chains of the spreading mass is cut off, and pores and cracks are formed on the surface of a size membrane, so that the penetration of desizing working liquid can be facilitated; and meanwhile, hydrophilic groups such as hydroxide radical, carboxyl group and the like are introduced into the plasma, the dissolving of the size membrane and the removal of impurities can be favored, so that the desizing rate of the fabric is improved. The experimental result shows that the desizing rate of the fabric can reach up to 85 percent or more by utilizing the desizing method, and the capillary and mechanical property of the obtained fabric can be improved.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular to a fabric desizing method. Background technique [0002] The desizing treatment of traditional textile printing and dyeing refers to the process of removing the size on the fabric and the impurities attached to the fabric fiber. The warp yarns of fabrics such as cotton, viscose and various synthetic fibers are mostly sizing before weaving. The size in the sizing process can affect the wettability of the fabric during the dyeing and finishing process and hinder the contact of chemicals to the fiber. Therefore, the fabric must be desized before dyeing and finishing. Commonly used desizing methods include: alkali desizing method, enzyme desizing method, oxidant desizing method and alkali-oxygen one-bath desizing method. [0003] Alkali desizing method is suitable for starch or starch-based fabrics with low sizing rate and fabrics mixed with chemical sizing (such as po...
