Abstract
A nonwoven composite fabric having first and second fibrous layers reinforced by an intermediate scrim layer. The first fibrous layer may be an entangled fabric formed of staple length fibers or continuous filaments, and the second fibrous layer may be a thermally point-bonded fabric formed of staple length fibers or continuous filaments. The second fibrous layer bonds the scrim to the first fibrous layer and will mask the scrim in the finished product. The composite fabric is produced by placing the scrim in face-to-face juxtaposition with the first and second fibrous layers, and subjecting the resulting composite to the forces of high pressure fluid jets to break the bonds in the second fibrous layer and to cause the fibers or filaments of that fibrous layer to pass through the openings in the scrim and become entangled with the fibers or filaments of the first fibrous layer.
