Rotor open end spinning -Introduction to Open End Spinning

1.In conventional spinning ,the fibre supply is reduced to the required mass per unit length by drafting & then consolidated into a yarn by the application of twist.
2.There is no opportunity for the internal stresses created in the fibres during drafting to relax.
3.In open end spinning, the fibre supply is reduced, as far as possible , to individual fibres, which are then carried forward on an air-stream as free fibres.
4. This permits internal stresses to be relaxed & gives rise to the term “free fibre spinning”.
5.These fibres are then progressively attached to the tail or “open end” of already formed rotating yarn.
6.This enables twist to be imparted by rotation of the yarn end.
7.Thus the continuously formed yarn has only to be withdrawn & taken up on a cross-wound package.
