Strong-twisted yarn, a kind of yarn formed by twisting, after being shaped at high temperature so that the yarn is not knotted and heightened.Strong twisted yarn refers to yarns that have certain physical and mechanical properties such as elasticity, elongation, luster, and feel of the yarn. The cotton yarn must be changed by twisting, and the fiber structure is used to realize the yarn twisting. In fact, it uses the relative angular displacement between the cross-sections of the cotton yarn to tilt the original straight and parallel fibers and the yarn axis to change the yarn structure. The thick strips gradually shrink in width during the twisting process, and the two sides gradually fold and become involved in the center of the yarn strip, forming a twisted triangle. In the twisted triangle, the width and cross-section of the cotton strips change from a flat strip to a cylindrical yarn.

At present, the classification of strong-twisted yarns mainly has the following specifications：

Strong-twisted cotton yarn, strong-twisted polyester yarn, viscose strong-twisted yarn, polyester-viscose strong-twisted yarn, polyester-cotton strong-twisted yarn, etc., Other varieties can also be made into strong-twisted yarns, which are formed by twisting.At present, the strong-twisted yarns produced by the company are all shaped at high temperature, with high strength, high twist and no knotting, which is the best choice for the majority of customers.
