Conclusions

An effect of drawing temperature on the change in structural-mechanical properties of 111 tex polyester yarns during subsequent heat-treatment has been demonstrated.

Yarns drawn at temperatures below 190°C had a strength lower than yarns drawn at higher temperatures after heat-treatment.

The decrease in strength during heat-treatment is connected with the relaxation of significant internal stresses and rearrangement of the polyethylene terephthalate structure.
