The effect of simulated tire-building steps on morphological characteristics of polyethylene
terephthalate (PET) cords and their final dimensional stability is reported. Twisted single-ply
cords were sequentially processed for mimicking dip coating (without real latex treatment),
thermal curing (without embedding them in rubber matrix), and creep deformation. The
degree of crystallinity and crystalline orientation factor (f c) of the samples remained
essentially unchanged in the course of the simulated manufacturing steps. As measured by
birefringence, overall orientation of the cords increased in the coating step but decreased
during simulated curing. Overall orientation again increased after creep testing. As
measured by wide-angle X-ray diffraction, the cords having higher oriented amorphous
(mesophase) content displayed the least variation in overall orientation during processing
steps and the best dimensional stability.
