This disclosure relates to composite textile constructions formed by needle punching non-woven fibers into a layer of plastic material. In one embodiment a batt of non-woven fibers is needle punched into a plastic sheet and the composite laminate then hot calendered to press the punched fibers into the plastic sheet thereby forming a smooth surface. In another embodiment a non-woven batt is is needle punched into a heat-retractable plastic grid or shrinkable carrier. The grid is then caused to retract under dimensionally controlled conditions whereby the fibers in the unpunched portions of the batt will rise up in arch-like ridges or designs out of the plane of the batt thereby presenting a resilient textured surface. |
