20.  Introduction
 Rotor spinning or open-end spinning is a technology
for creating yarn without using a spindle. •It was
invented and developed in Czechoslovakia. •Open End
spinning is also known as break spinning or free fiber
spinning

21.  To provide a more economical spinning system than
conventional ring spinning through higher
productivity
 To produce yarn of a quality that matches or surpasses
that of the conventional ring spinning.

23. Sliver feeding.
Sliver Openning.
Fiver transfer to the rotor.
Fiber collection to the rotor groove.
Yarn formation.
Yarn take –up or winding.

25.  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.

26.  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.

33.  At last we would like to say that presentation taken at
spinning has broadened our knowledge and has widened
our thinking as a profession.
