Abstract
This paper reports on some properties of kenaf/polyester blended yarns which were spun using rotor spinning at different rotor speeds and fibre blends ratio. The blended yarns were spun at 50,000; 60,000; and 70,000 rpm rotor speeds. The kenaf and polyester fibres were mixed at the carding process at percentages of 5/95, 10/90 and 15/85, respectively. The size of the yarn was kept constant at 40 Tex. It was found that with higher percentage of kenaf fibres, the yarn tensile strength decreases at every rotor speed. The yarns produced from 5/95 blending ratio at rotor speed of 60,000 rpm have the highest strength among the other yarn samples. The yarn imperfections also showed similar trend as the tensile strength. The study also showed that the yarn evenness and imperfections were lowest for yarns with the least percentage of kenaf fibres.
