Problems solved by technology

However, the dissolution rate of cellulose acetate in ionic liquids is relatively low, generally around 3%-15%, and relying solely on the plasticizing effect of ionic liquids cannot make the strength of a high-proportion blend of cellulose acetate blends reach a satisfactory level.

Abstract

The invention provides a blended material with high cellulose acetate content and a preparation method thereof. The present invention proceeds from two aspects. On the one hand, the strength of the acetate fiber itself is enhanced to improve its anti-break performance; Abrasion resistance, and significantly improve the wet strength of the material. Through the above treatment, the weak point of poor mechanical strength of acetate fiber can be eliminated, so the content of acetate fiber can be increased in blended materials, so that acetate fiber has good touch, good air permeability, no static electricity and easy coloring. The properties can be preserved in the blended materials to the greatest extent.

Description

Technical field [0001] The invention relates to the technical field of textiles, in particular to a blended material with high acetate fiber content and a preparation method thereof. Background technique [0002] Acetate fiber is a chemical fiber clothing material made by spinning cellulose acetate as raw material. Acetate fiber can produce soft, smooth, almost silky touch, good air permeability, no static electricity, easy to color and stable after coloring, so it has excellent wearability. Moreover, the energy consumption and water consumption of acetate fiber production are low, the pollution is small, and the comprehensive benefits are significant. [0003] In traditional applications, cellulose acetate can be used as the inner lining of clothing to take advantage of its good touch when worn on the skin. Acetate fiber can also be used for blending with real silk. It is worth noting that in recent years, the scope of application of acetate fiber has been continuously expanded,...
