Producing high strength polyester fibres with reduced wear comprises first thermal treatment at 230 to 250 deg.C under vacuum. After mixing with a dye the fibres are passed through an extruder at temperatures of 268 to 295 deg.C. The filaments obtd. are submitted to a hot drawing process at 100 to 235 deg.C and rates between 1:5.75 and 1:5.95.
