The impact of yarn twist could be very different in the case of rotor-spun yarns owing to rotor yarns structural difference with ring-spun yarns. The effect becomes even more complex because of the non-homogeneous characteristics of the blend fibres. This study reports the contribution of twist to the breaking strength, extension at break, and any association between twist loss and yarn unevenness in acrylic-viscose rotor-spun yarns.
