What is twist yarn?

Twist yarn refers to the relative rotation of two sections of yarn, when the fibers in the yarn which are parallel to the yarn axis are inclined into spiral lines. For short fibers, twisting is mainly to improve the strength of yarn. The twisting of filament can not only improve the strength of yarn, but also produce stereoscopic effect. The amount of twist and the matching of twist direction and twist of yarn in fabric have a great influence on the appearance and performance of the product. Therefore, the price of twist yarn is higher than that of the original yarn. Twist direction refers to the inclination direction of single yarn in single yarn or strand after twisting. There are two types of S-twist and Z-twist, S-twist = hand twist, Z-twist = reverse hand twist. Any single share will have a twist.
