Conclusions
An interconnection has been found between the conformational composition of the polyethylene terephthalate structure and fatigue properties in specimens of technical polyester yarn.
It has been shown that heat-treatment with an assigned shrinkage of about 14% permits one to increase the resistance of a yarn to double bending by a factor of 2 to 2.5.
