ABSTRACT:
In a washing method, a web of textile goods is wetted with a washing-active liquid and the liquid is caused to foam by steam which is blown at high pressure into a back side of the web of goods with a pile on the front side. The steam is discharged from a nozzle slot that extends transversely across the web of goods. The nozzle directs the steam against the web and through it. The foam which then suddenly forms is then drawn off by a vacuum or suction together with the liquid still in the pile from the pile side of the web.
