Com4®rotor – rotor-spun yarn

The fully automated Rieter rotor spinning machine produces a virtually faultless rotor yarn, Com4®rotor, with yarn-like piecings. In comparison with standard rotor yarns, Com4®rotor yarns achieve maximal tenacity with minimal twist. The low variation of yarn strength enables high level of productivity in downstream processing. Special features of the fabric are the invisible piecings and high resistance against abrasion.

Possible yarn variants:

  • vario – fancy yarn

Com4® yarn characteristics:

  • High optical evenness
  • Low variation in strength
  • Designable hairiness

  • Reduced generation of dust and fibre fly

Fabric appearance:

  • Very uniform fabric appearance
  • High abrasion resistance
  • Good appearance after raising

Typical end products:

  • Denim
  • Workwear
