Advantages and disadvantages

Index

Advantages are as follows:

  • high delivery speeds;
  • low yarn production costs (lower than those of ring spinning);
  • elimination of rewinding;
  • low end breakage rates;
  • yarn character similar to that of ring-spun yarn;
  • no wrapping fibers;
  • optically good mass evenness (well suited to knitted goods);
  • better and softer handle than that of rotor-spun yarn;
  • smooth yarn appearance.

Disadvantages are:

  • low yarn strength;
  • high tendency to snarl;
  • higher number of fibers needed in yarn cross-section;
  • difficulty of keeping spinning conditions constant;
  • high air consumption;
  • increasing unevenness and imperfections with increasing spinning speed, and further reduction in yarn strength.
