It is observed that coarse yarns produced using the same conditions are substantially weaker, less extensible, less irregular and more rigid than finer ones. The yarn breaking strength and breaking extension show an increase with the increase in polyester content, first nozzle pressure and feed ratio. The flexural rigidity decreases with a small gap between the first nozzle and the nip of front roller, a lower first nozzle pressure, lower yarn tex and a lower feed ratio.</span>
