The structural characteristics of ring yarn and rotor yarn are briefly described.

Answer: Compared with ring spinning, rotor spinning has more twists, uniform fabric surface, clear lines, fewer defects and full and thick hand feel. The core twisting mode of the two yarns is the same, and the straightness and orientation of the fibers are almost the same. However, because rotor spinning belongs to air spinning, its technological characteristics lead to the rotor yarn being bound by the wrapped fibers on its surface, and these wrapped fiber binding layers can not be untwisted; On the contrary, ring spinning yarn can be completely untwisted in the reverse direction, and two kinds of yarns can be distinguished by this method when identifying fibers.
