Process for the production of polyamide-6 filament yarns

A process for the continuous production of stretched and twisted polyamide-6 filament yarns from polyamide-6 melts by extruding the melt through spinnerets, cooling the filaments by blowing air onto them in the spinning duct, wetting the bundle of filaments with an aqueous preparation and running off the filament yarn with a take-off unit around which the filament yarn passes at least once, followed by direct stretching with a stretching unit and winding into package form, wherein, before stretching, the filament yarn is interlaced in such a way that it has a hook-drop value of at most 200 mm and wherein the filament yarn is treated after stretching at temperature above 110.degree.
