ABSTRACT:
A process is provided for the manufacture of filament yarns having fine protruding filament ends, which comprises subjecting filament yarns, wherein at least part of the filaments consist of polymers the lateral bending resistance (Knickscheuerbestandigkeit) of which can be thermally influenced, to an intermittent sectional treatment, thus ensuring that determined sections of the filaments have a low lateral bending resistance, and by subsequently breaking these sections of low lateral bending resistance by transverse stress, which causes formation of the desired free filament ends.
