Abstract
A pile carpet after tufting or the like is usually provided on the back with a latex precoat for stabilization and then provided with a foam back or an additional jute fabric. This environmentally hazardous method and the problem of recycling the foam back as well as the latex layer can be avoided If a nonwoven is applied instead to the tufted back of the carpet by water needling. This is possible with water needling in that the solidification of the pile fibers in or on the primary carrier takes place but no nonwoven fibers reach the visible side of the carpet. The back layer to be needled can also be made thicker and mote voluminous. Instead of a carpet, any other pile goods can also be stabilized in this fashion.
