THE EFFECT OF TRAVELLER SPEED ON THE QUALITY OF RINGSPUN YARNS AT LOW SPEEDS

Abstract

Ring spinning is the most common method for spinning yarn. Various parameters of the ring spinning machine affect the quality of yarn during the spinning process. The effect of ring traveller weight and spindle speed on yarn quality was investigated in this research. Yarn was prepared by using two spinning speeds, 6500 rpm and 9500 rpm. Three different travellers were then used at each of the two spinning speeds to produce 42Tex yarn. The yarn hairiness, twist levels and tensile strength were used to evaluate the quality of the produced yarn. Results showed that there was a decrease in the yarn hairiness as the spindle speed and traveller weight were increased while there was no observed trend in twist level. In relation to the tensile strength there was higher strength when yarn was spun at 6500 rpm and higher strength was observed when the F5 traveller was used at both speeds.
