In the textile industry, post-processing of fiber fabrics is crucial. Natural fibers such as cotton, linen, wool, and silk have acquired specific colors and functions after bleaching, dyeing, printing, or functional finishing, but the fibers are damaged due to the removal of wax and oil. The fabric becomes rough, the luster is gone, and the sewing performance is greatly reduced. The hand feel of synthetic fibers is originally inferior to that of natural fibers. After high-temperature shaping, the roughness and hardness of the hand feel are more prominent. In order to improve the quality of fabrics, give them a soft and comfortable hand feel, and enhance their comprehensive performance, soft finishing has become an indispensable link. It can not only improve the touch of the fabric, but also repair fiber damage to a certain extent, and enhance the market competitiveness of the product.
