Abstract
The properties of cords made from fibers with superior modulus/shrinkage characteristics have been studied, and the implications of these properties on tire performance have been addressed. The cord-modulus, dimensional-stability, stress-amplification, and retractive-force trends are comparable to those of the precursor yarns, indicating that the yarn morphology yielding these properties is maintained in tire-cord form. One would expect that these cords could be used to make tires with improved uniformity, bruise-resistance, and handling, and reduced sidewall indentations.
