Abstract:
1. A process for making a stitchbonded fabric comprising the steps of (A) providing a substrate material having two outboard edges along the machine direction, and providing a continuously operable multi-needle stitching machine, (B) feeding the substrate material to an entrance of the stitching machine, (C) slitting the substrate material at one or more positions intermediate the outboard edges, thereby producing a slit in the substrate material at each of said positions defining opposing lips, the slit extending in the machine direction, (D) folding at least one lip outward in contact with the substrate material adjacent the slit thereby forming a discontinuous base layer comprising a multilayer region of the substrate material extending in the machine direction and an open space region of the base layer extending in the machine direction and adjacent to the multilayer region which open space region is devoid of substrate material, and (E) multi-needle stitching of threads throughout the extent of the discontinuous base layer by threads in the open space region and in the at least one lip of the substrate material with at least one pattern of stitches in rows running in a machine direction and spaced apart in a cross direction, thereby forming an integrated fabric of stitched-over substrate areas of the base layer.
