Process and device for flushing of textile goods

Abstract

Under a process or a device for rinsing/flushing of rope-formed textile product JET-processing Machines, the textile product in the form of an endless fabric rope is put in rotation through a Venturi-Nozzle in a vessel by means of a gaseous transport medium. The flushing/rinsing is done with the rinsing liquid brought on the fabric rope in the fabric rope movement direction before and/or in and/or after the nozzle. In the process, the rinsing liquid application per time-unit and/or the speed of the fabric rope rotation is controlled based on the product-specific data of the textile article and/or on machine-specific and/or process-specific data.
