Popis:	In present day practice the tenacity of homopolymer fibers is increased by using the highest possible temperature and draw ratio while suppressing the processes of thermal disorientation /1,2/. In the single-stage stretching of amorphous isotropic fibers spun from polyethylene terephthalate (PETP) these conditions are difficult to achieve owing to the high mobility of the molecules at temperatures above 160°C /3;4,pp.75-90;5/ so that various methods have been proposed for increasing the tenacity of polyester fiber by stretching in several stages.
