The strength of cashmere yarn depends on the cohesion and friction between the fibers. If the shape and placement of the fibers are not good, that is, there are fibers such as twists, loops, half, and loops, which is equivalent to shortening the length of the fiber and weakening the touch of the fiber, so slip between the fibers is prone to occur. Decrease the strength of cashmere yarn.
According to experiments, if the strength of ring yarn is 1, then the strength of other types of yarns are: rotor yarn 0.8～0.9, air-jet yarn 0.6～0.7, vortex yarn 0.8, tight spinning strength is the highest 1.15
