What are the characteristics of yarn wear resistance and yarn structure?

The wear resistance of yarn is closely related to the structure of yarn.

Traditional ring spinning yarns are mostly spiral fibers. When repeatedly rubbed, the spiral fibers gradually become axial fibers, and the yarn is easy to lose twist and disintegrate, which leads to rapid wear and poor wear resistance.

Non-traditional spinning has obvious advantages in wear resistance. Rotor yarn, air-jet yarn and vortex yarn are all composed of yarn core and wrapped fiber. The surface of the yarn is covered with irregular wrapped fibers, which makes the yarn not easy to disintegrate. At the same time, the friction coefficient of the yarn surface is large, the yarn has good cohesion in the fabric, and it is not easy to produce relative slip, so the wear resistance is improved.
