A continuous supply of fibres either in the form of a sliver or straight from the cotton opening unit is sucked down a fibre delivery tube and into the rapidly rotating rotor. The fibre is peeled, at speed, from the grove in the rotor, through the trumpet, through the yarn tube and at the same time twisted, then through the take off rollers and wound onto a package. In comparison with ring spun yarns, for instance, rotor spun cotton yarns are:

  • More uniform in appearance
  • Less variable in strength
  • not as strong
  • more extensible
  • bulkier
  • more absorbent
  • more abrasion resistant
