ABSTRACT:
Hollow polyester undrawn filaments having excellent mechanical quality and uniformity are prepared by a simplified post-coalescence melt spinning process at speeds of e.g. 2-5 km/min by selection of polymer and spinning conditions whereby the void content of the undrawn filaments can be essentially maintained or even increased when drawn cold or hot, with or without post heat-treatment.
