S+Z twist can effectively disperse external forces, making the yarn more elastic and resistant to breakage when stretched or impacted. This alternating twist structure allows the yarn to provide a more uniform force distribution when responding to external pressure, avoiding the risk of easy breakage caused by a single twist, thereby greatly enhancing the durability and resistance to wear of the yarn. The improved toughness of the yarn makes it more stable in high-intensity use situations, reducing damage and deformation of the fabric.
