Abstract

A process for the production of a face-to-face carpet fabric on a double pile loom having at least two filling insertion planes, uses filling yarns, stuffer warp yarns, and chain warp yarns to form two back cloths. The filling yarns are inserted into each back cloth as back fillings and inner fillings. Groups of chain warp yarns, individual yarns of which between their respective last binding to an inner filling and the succeeding last binding to a back filling form a holding length, are assigned to each back cloth. All patterning pile loops are stretched over back fillings. and the pattern repeat of a group of chain warp yarns is selected to be greater than six. The holding lengths of a chain warp yarn extend over at least three filling insertion cycles.
