Wear resistance is an important index of textile product quality, which directly affects the durability and use effect of the product. Specifically, it refers to the wear resistance of fabrics or other materials in the process of repeated friction.
The abrasion of textile products is mainly manifested in the following five aspects:
(1) In the process of friction, the fibers collide with each other continuously, and the fiber segments in the yarn break due to fatigue damage, which leads to the breakage of the yarn.
(2) When the fiber is pulled out of the fabric, the structure of the yarn and fabric will be loose. Under the repeated action, the fiber may be pulled out completely, resulting in the yarn thinning, fabric thinning and even disintegration.
(3) The fibers are cut and broken, causing the yarn to break.
(4) The surface of the fiber is worn and the debris is lost.
(5) Friction produces high temperature, which makes the fiber melt or plastic deformation, and affects the structure and mechanical properties of the fiber.
The main changes of wear are damage, loss of quality, discoloration of appearance, pilling and so on.
There are many methods to test the wear resistance of textile products, such as flat grinding, curved grinding, flanging grinding and compound grinding. Martin Dale method is a kind of flat grinding method, which is widely used in the wear resistance test of clothing, home textiles, decorative fabrics and furniture fabrics.
