If one end of the spinning is held and the other end rotates, the yarn can be formed. This process is called twisting.

Twisting design affects the physical and mechanical properties and appearance of tows, yarns and lines, and then has a great impact on the properties, appearance and use value of fabrics.

For staple yarns, twisting is a necessary means to obtain strength and other properties; for filament yarns and ply yarns, twisting can form a compact structure which is not easily damaged by lateral external forces. Twisting can also form textured yarns and fancy lines. The amount and direction of twisting affect not only the feel and appearance of the fabric, but also the intrinsic quality of the fabric.
