摘要

The influence of twist factor and rotor speed on the properties of polyester ring and rotor yarns spun from polyester fibres of circular and trilobal cross-sections has been studied. The results show that the fibre profile plays a key role in determining the mechanical and surface properties of all-polyester, polyester-viscose and polyester-cotton yarns, as evidenced by the fact that both ring and rotor yarns spun with trilobal polyester fibres have lower tenacity, higher breaking extension, more twist liveliness, lower work of rupture and higher flexural rigidity. Furthermore, lesser yarn-to-metal friction, higher dye pick-up and low hairiness can be obtained for blended yarns having polyester fibres of non-circular cross-section. Both twist factor and rotor speed strongly affect all yarn properties and the behaviour is similar for all the yarns.
