Abstract

Process for the manufacture of filaments from linear polyesters of high molecular weight, characterized in that the filament is stretched, passed on or around one or more rollers having a surface temperature between 230 and 280ºC for a total time of contact between 0.02 and 0.5 seconds, and then allowing the filament to relax under tension between 0.2 and 10 p/tex, calculated on the final filament heading.
