摘要

Process for improving the properties of hot-drawn or hot-drawn yarns of high-strength polymeric e-caprolactam characterized by the fact that the yarns are subjected to a heat treatment at temperatures between 200º and the melting point under the treatment conditions preferably between 210º and 220º with the use of a tension that lies between the corresponding force of contraction and 90 of the breaking load, preferably comprised between 055 g/den and 25 g/dec to avoid shrinkage and swelling or oxidation.
