Problems solved by technology

[0006] In order to improve the anti-felting performance of wool fabrics in the above-mentioned patented technical solutions, protease is used to enzymatically destroy the scales on the surface of wool fibers, so that the degree of crosslinking of the scale layer on the surface of wool fibers is reduced, thereby improving the anti-felting performance of wool fabrics. However, when protease is used to enzymolyze the scale layer on the surface of wool fiber, protease enters the interior of wool fiber from the gap between the scale layers on the surface of wool fiber, causing damage to the internal tissue structure of wool fiber, thereby reducing the mechanical strength of wool fabric

Abstract

The invention relates to the technical field of fabric modification, and discloses a wool fabric anti-felting finishing method with high-strength retention rate. The method comprises the following steps of 1) putting the wool fabric into a hydrogen peroxide treatment liquid for oxidation treatment to obtain a wool fabric a; 2) adding the wool fabric a into an epoxy propyl dodecyl diethyl ammoniumchloride solution for surface modification to obtain the wool fabric b; 3) preparing composite protease microspheres; and 4) enabling the wool fabric b to be soaked into a finishing liquid comprisingthe composite protease microspheres for soaking finishing. The finishing liquid comprising the composite protease microspheres is adopted for finishing the wool fabric, strong damage to the wool fibers caused by the fact that the protease falls into the wool fibers from the space between scale layers on the surface of the wool fibers is avoided, and the wool fiber obtained through finishing has excellent anti-felting performance and high strength retention rate, thereby obviously improving the wearing property of the wool fabric.

Description

technical field [0001] The invention relates to the technical field of fabric modification, in particular to an anti-felting finishing method for wool fabric with high strength retention rate. Background technique [0002] Wool has a long history in the textile field. It can be traced back to the Neolithic Age. It is one of the natural fibers used by humans earlier. Because wool fibers are soft, fluffy and elastic, the fabrics made are comfortable, warm, and full-feeling. Characteristics that make common home and industrial textile materials. However, wool fabrics are prone to felting due to non-directional external forces during washing, resulting in poor softness and elasticity, and affected dimensional stability, which seriously affects wearing performance. Therefore, wool fabrics need to be anti-felted. Shrink finishing. After observation, it is found that the tissue structure of wool fiber includes scale layer, cortex layer, and medulla layer. The scale layer is compo...
