Effects of rotor spinning parameters on microdust accumulation from a low-middling grade cotton

<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" calibri;mso-fareast-theme-font:minor-latin;mso-hansi-theme-font:minor-latin;="" mso-bidi-font-family:"times="" new="" roman";mso-ansi-language:en-us;mso-fareast-language:="" en-us;mso-bidi-language:ar-sa"="">The effects of opening roller speed, rotor diameter and rotor speed on rotor deposits were studied. The mass of accumulated trash particles in the rotor groove increased with increases in these spinning parameters. Opening roller speeds which gave a calculated value of less than 1.5 mg for the fibre mass per tooth caused a marked increase in the accumulated mass of rotor deposit. Expectedly, deterioration was observed in the yarn quality with increased trash accumulation, but this appeared to be less than that attributable to increased rotor diameter and speed.</span>
