Abstract
Manufacture of polyester yarns by a high speed draw spinning process in which the yarns are passed through a first fluid environment heated to a temperature above the melting point of the material of the filaments then through a second fluid environment heated to a temperature above the glass transition temperature of the material of the filaments and then winding up at a speed in excess of 5500 metres/min. Yarns are comparable in properties with conventional spin-lag- draw hot relax yarns.
