Abstract

A process for improving the tenacity of a filament having a tenacity of at least one gram per denier and formed from a synthetic linear condensation polymer, characterized in that the polymer is capable of forming an anisotropic melt and that the filament is subjected to heat treatment at a temperature below the flow temperature of the filament and in an inert below the flow temperature of the filament and in an inert a atmosphere and while the filament is in an essentially relaxed condition, the said treatment being conducted until the filament tenacity is improved by at least 50% and exceeds 10 grams per denier.
