|Abstract:||The influence of add-on spin finish and opening roller speed on the properties of polyester OE rotor yarns spun from fibres of different cross-sectional shapes and linear densities has been studied. The level of spin finish appears to have highest influence on the yarn characteristics followed by the opening roller speed and fibre linear density. Higher level of spin finish offers significant advantages in respect of yarn tenacity, breaking extension, work of rupture, abrasion resistance and hairiness but adversely affects regularity and flexural rigidity. Each of these quality parameters deteriorates to different degrees with the increasing opening roller speed. There is also decline in properties when yarns are made from a trilobal fibre. Such a decline in properties at high opening roller speeds is, however, less marked in yarns spun from fine denier fibres .|
