Abstract

The invention relates to a nursing and anti-felt finishing method for wool fabrics based on the compounding of keratin polypeptide and water-based polyurethane (WPU). It is formulated into a finishing solution, which is finished on the wool fabric by the traditional padding method. After pre-baking and baking, the keratin polypeptide and WPU are cross-linked to the surface of the fabric fiber, so as to realize the care of the fabric and the anti-felt finishing. The method has a simple technological process and greatly reduces the amount of WPU used in traditional wool anti-felt shrinkage prevention. The wool fabric treated and anti-felting by the method not only has good dimensional stability and wrinkle recovery performance, but also can improve the breaking strength and softness of the wool fabric.

Description

technical field [0001] The invention belongs to the technical field of fabric care and finishing, and relates to a wool fabric care and anti-felting finishing method based on the compounding of keratin polypeptide and WPU. Background technique [0002] Wool fiber has many excellent properties, such as soft touch, good elasticity, good warmth retention, soft luster, and easy decontamination. Various high-grade fabrics can be made from wool, which is favored by consumers for its superior performance. However, due to the felting of wool fabrics during daily wear and washing in conventional washing machines, the performance of the fabrics is greatly affected. [0003] As a major producer of textile fibers and textiles, my country has a large number of non-spinnable short fibers, coarse fibers, and defective animal hair and animal fiber waste that are damaged by processing, which are discarded every year. There is a serious waste of resources and insufficient development. At th...
