Abstract (en)
[origin: WO2022184696A1] The invention is based on a process for producing at least one filament (12), in particular an artificial-grass filament, a packaging band or a monofilament, preferably a group of filaments, with at least one stretching step (14), in which the at least one filament (12), in particular the artificial-grass filament, a packaging band or a monofilament, is stretched, wherein water vapour (18) is made to flow around the at least one filament (12), in particular the artificial-grass filament, a packaging band or a monofilament, in a vapour-depositing region (16) before and/or during stretching. It is proposed that at least one vapour parameter of the water vapour (18) located in the vapour-depositing region (16), in particular in the form of dry vapour, is controlled to counteract the formation of droplets on the at least one filament (12).
