ResumoThis paper mainly discussed the twist structure and property difference between in-phase self-twist yarn and phased self-twist yarn. There are three kinds of zones along the yarn: the twist-twist zone, twist-notwist zone and notwist-notwist zone in one cycle length of self-twist yarn. The existence of the phase difference makes the length of the notwist-notwist zone decrease. When the size of the phase difference (value c)is closer to or equal to the length of the zero zone(value b), the minimum length of the notwist-notwist zone will be obtained so that the best properties of self-0twist yarn can be achieved. The result for in-phase and phased self-twist yarn shows that the above conclusion is correct.
