Abstract: The effect of twist on the mechanical properties of twisted textured polyester yarns was studied. 80 denier textured polyester yarns were twisted with various tex twist factor (Tex1/2 turns/cm) from 9 to 108. With increase in twist, the yarn tenacity first increased and then gradually decreased, the elongation at break increased up to a twist factor of 72 and then remained nearly constant, the work of rupture first increased sharply and then decreased sharply, and the yarn diameter decreased sharply up to a twist factor of 27 and then remained constant.
