ABSTRACT:
Fabrics having strength despite low bulk density and comprising at least one reinforcing layer of textile-length fibers, at least one layer of short bulk fibers and a bonding agent distributed throughout said fabric layers. Also a process for producing a fabric having a layer of such bulk fibers disposed between two of such reinforcing layers and a process for producing a fabric having a surface layer of such bulk fibers wherein a multi-layered structure containing an interior layer of such short bulk fibers is split along a continuum of lowered bonding agent concentrations at locations predetermined by controlled heating of the structure.
