A system of spinning using a ring and traveler is known as ring spinning. Ring spun yarn is stronger than open end yarn.

A spinning system in which fibers are twisted and wrapped around each other by the use of a rapidly rotating rotor.

A spinning system in which yarn is made by wrapping fibers around a core stream of fibers with compressed air. Fibers are fed to the air jet chambers where they are twisted, first in one direction, then in the reverse direction in a second chamber.

This is the attachment for ring spinning machine, in this system the fibers are compacted by air for making yarn.

This is very good yarn concerning, strength % and TPI value, hairiness and evenness.
