ABSTRACT:
A method for producing substantially 100% polyester yarns on an open end spinning machine is described. The process involves acting on substantially 100% polyester sliver made of high tenacity, fine denier fibers with a negative tooth combing roll to individualize the fibers and feed them to the rotor of an open end spinning machine. Superior quality industrial gauge yarns can be produced from fine denier, high tenacity polyester fibers according to this method at a high rate of throughput and with few ends down.
