Abstract: An air-jet nozzle for cone winding machine was designed and fabricated to decrease the hairiness of yarn and, thereby, to control the deterioration in yarn quality. Yarn quality improvement in five different counts (two carded and three combed) was studied using air- jet nozzles of three different orifice angles (30°, 45° and 60°) and three different air pressures (0.5 kg/cm2, 1.0 kg/cm2 and 1.5 kg/cm2). It has been observed that the best results are achieved with air-jet nozzle of 60° orifice angle and 1.0 kg/cm2 air pressure. Using this nozzle during winding, the hairs in ring yarn decrease by 50-75%. Hence, the use of air-jet nozzle in cone winder helps to maintain the quality of wound yarns at par with that of ring yarns.
