Abstract: The spinning performance and yarn quality of an Indian Cotton (J-34) was studied by spinning it to 10S, 16S and 22S yarn over a range of rotor speed (30,000-50,000 rpm) and combing roller speed (4000-9000 rpm). The strength of yarn decreased and yarn unevenness and imperfections increased as the rotor speed was increased. The minimum spinning twist was, however, lower at higher rotor speeds. Too low speed of combing roller (e.g. 4000 rpm) resulted in poor yam quality and higher minimum spinning twist. There was practically no improvement in yarn quality and the minimum spinning twist at combing roller speeds higher than 7000 rpm.
