1. A method for producing at least one filament, in particular an artificial-lawn filament, a packaging tape or a monofilament, with at least one stretching step in which the at least one filament, in particular the artificial-lawn filament, the packaging tape or the monofilament, is stretched, wherein the at least one filament, in particular the artificial-lawn filament, the packaging tape or the monofilament, is in a vapor-depositing region flown around by water vapor before and/or during the at least one stretching step, wherein at least one vapor parameter of the water vapor located in the vapor-depositing region, in particular in the form of dry vapor, is controlled so as to counteract a formation of droplets on the at least one filament, wherein the vapor parameter is monitored by at least one sensor element of a vapor-depositing apparatus, wherein a control or regulation unit of the vapor-depositing apparatus or of a filament-production installation comprising the vapor-depositing apparatus adjusts the vapor parameter such that a condensation of the water vapor on the filament is counteracted.
