The effect of yarn linear density, yarn structure, twist factor and rotor speed on low-stress properties of mercerized cotton ring- and rotor-spun yarns has been studied. For both ring- and rotor-spun yarns, the initial modulus at 1% and 3% extensions, packing density and hairiness change markedly as a result of mercerization treatment. Flexural rigidity increases significantly, however it is considerably lower for ring- spun yarns. The abrasion resistance of both types of yarns decreases but yarn twist increases it.
