Abstract

Yarns are prepared by spinning PEN or other semi-crystalline polyester polymers made from similarly rigid monomer combinations to a state of optimum amorphous orientation and crystallinity.
This is accomplished by selection of process par-ameters to form an undrawn polyester yarn of birefringence at least 0.030. The spun yarn is then hot drawn to a total draw ratio of between 1.5/1 and 6.0/1 with the resulting drawn semi-crystalline polyester yarn having Tg greater than 100°C and a melting point elevation at least 8°C. The preferred yarn has a tenacity at least 6.5 g/d; dimensional stability (EASL + Shrinkage) of less than 5 %, and shrinkage 4 % or less. The resulting yarn exhibits surprisingly high modulus and tenacity together with low shrin-kage when compared to prior art yarns.
