Classification and Principle of Open End Spinning

 Open-End Spinning :

There are two commonly used yarn manufacturing methods operating on the open-end spinning principle: 

1. Rotor 

2. Friction. 

1. Rotor :

The rotor system is mainly used for the production of coarse to medium count short staple yarns. 

2. Friction. 

The friction system is used mainly to make coarser industrial yarns. However, both systems may also be used for making some fancy yarns.
