Abstract

A process for the preparation of an improved poly (p-phenyleneterephthalamide) fiber by heating a poly (p-phenylenterephthalamide) fiber with an inherent viscosity of at least 4.0, a density of at least 1.40 g/cm3, an orientation angle less than 22º and an apparent size of crystallites less than 52 Å under tension, in a zone maintained at 150ºC at least, for a period of time sufficient to give an apparent size of crystallites greater than 58 Å and an orientation angle of not more than 13º, the method of which is characterized in that the starting fiber has a lateral birefringence of at least 0.02, the tension is at least 0.5 g/denier but less than the required tension to stretch the fiber more than 1.03 times its original length at that temperature and because the heating time is such that the original tensile strength and inherent viscosity of the starting fiber do not decrease by more than 30%.
