Abstract

Process for obtaining polyamide yarns endowed with improved mechanical characteristics, characterized in that a polycaproamide yarn is continuously stretched, heated continuously at temperatures to which it would contract if it were free, while said contraction is substantially impeded, and because it cools to a substantially constant length before its re-rolling.
