Abstract: The effect of friction ratio on yarn quality has been studied for two different modes of yarn formation (DREF-II and DREF-III). It has been observed that for DREF-II yarns the tenacity follows a similar trend with friction ratio as it follows with twist for ring yarns, whereas the breaking extension tends to increase with the increase in friction ratio. However, the tenacity and breaking extension of DREF-III spun yarns remain more or less constant after an initial increase with the increase in friction ratio. Further, irrespective of friction ratio, the DREF-II yarns spun at lower delivery rates are more uniform whereas reverse is observed for DREF-III yarns.
