Machines used in short-staple fiber spinning and there operations

 Staple fiber (i.e raw cotton, flax, Hemp, wool) that can be twisted to form yarn is called staple fiber and it can vary in length. Around 33 million tons approx. processed as staple fiber every year in the world annual fiber consumption. It become important to know about the technology which is required to convert the raw material to semi finished or fully finished product.
