Hairiness degree is of great important for yarn motion during air - jet filling insertion . therefore the hairiness degree of gray, waxed, dyed, singed and mercerized single / plied yarns was measured and analysed. Also yarn motion during air-jet filling insertion for previous mentioned yarns were measured and analysed experimentally. The results indicated generally that, the single yarns were showed a higher degree of hairiness than that of plied yarns. Also the waxed yarns of both types were showed the best motion behavior than the other yarns. The results indicated also that weft velocity increases by the increase in main nozzle pressure.
