Open- End Spinning The term “ open- end spinning ” has constantly been used as a reverse for all new styles of making yarn. This is incorrect, and “ open- end ” should be applied only to systems where a break occurs in the fiber system. Break spinning and open – end spinning is synonymous.

 The essential way in open – end spinning include the following. A coarse splinter of filaments is fed to and opening system which opens the splinter to the point where the filaments are individual realities. The individual filaments are fed forward and also are collected together on a small face and pulled from the face as a thin subcaste constantly adding to the open end or tail of the forming yarn. The thin subcaste is downgraded, twist is fitted , and the performing yarn is wound onto bobbins. Two styles of open – end or break spinning are in use rotor spinning and fluid or air or whirlpool systems.

 Rotor spinning involves the contact of filaments in or on rotating bias similar as tubes, cones, sieves, or needled shells. A splinter of filaments is fed into the unit, a current of air forces the filaments into a loose form, and they're collected on the rotating device. As they're collected, they're pulled off the rotor by mechanical means to form the yarn, and the new yarn is wound onto packages. Twist is fitted as the yarn is removed from the rotor.
