Abstract

A process for the simultaneous texturizing and entangling of filament bundles by treating filament bundles of synthetic, high-molecular weight materials with a heated fluid in two tubular treatment chambers, in which process spatial or periodic irregularities are produced, in the treatment zones, in the flow of fluid and/or filament bundles. Preferably, a certain range of values of a volume mass flow factor is adhered to.
