There are various parameters during yarn production which can influence the quality of yarn. Two of them are the traveler weight and spindle speed on a ring spinning machine. This work was undertaken to study the effect of traveler weight and spindle speed on the quality of 21 Ne 100% cotton carded yarn. The C-type travelers were used for this study. Five different weights were used and tested at the spindle speed of 12000, 13000 and 14000 rpm. The yarn samples obtained by using different traveler¿s weights and spindle speed were investigated for hairiness, amount of twist, tensile strength, elongation. Results showed that there was a decrease in the yarn hairiness as the spindle speed and traveler weight at 14000 rpm and 50 milligram respectively.
