Wear resistance is an important indicator of the quality of fabric products, which directly affects the durability and use effect of the product. Specifically, it refers to the resistance to wear between fabrics or other substances in the process of repeated friction. Wear is manifested in the morphological changes of the fabric, mainly damage, loss of quality, discoloration in appearance, pilling and other changes.
The wear of fabric products is mainly manifested in the following five aspects:
(1) During the friction process, the fibers collide continuously, and the fiber segments in the spinning yarn break due to fatigue damage, resulting in the breakage of the spinning yarn.
(2) The fibers are drawn out of the fabric, resulting in the loosening of the spinning yarn and the fabric structure. Under repeated action, the fibers may be completely pulled out, resulting in thinning of the spinning yarn, thinning of the fabric, and even disintegration.
(3) The fibers are cut and broken, resulting in the breakage of the spun yarn.
(4) The surface of the fiber is worn, and the surface of the fiber is lost.
(5) The high temperature generated by friction causes the fibers to melt or deform plastically, which affects the structure and mechanical properties of the fibers.
