ABSTRACT:
A multi-ply fibrous material is provided which is suitable for use as a wipe, swab, or sponge and which comprises a backing layer and at least one liquid absorbent layer. The backing layer is made of compactly assembled natural wood pulp fibers, bonded to each other with an adhesive binder to provide wet strength. The liquid absorbent layer is made of loosely assembled fibers including both natural wood pulp fibers and wettable thermoplastic synthetic wood pulp fibers which are irregularly arranged, intersecting, overlapping, and mechanically interengaged segments of the thermoplastic synthetic wood pulp fibers being heat fused and bonded to the backing layer in a discontinuous pattern of embossed areas alternating with unembossed areas.
The aforementioned fibrous material is made by bringing together the aforementioned backing layer and at least one liquid absorbent layer, applying heat and pressure to the layers in a discontinuous embossing pattern and applying heat in the absence of pressure to the layers to heat fuse and bond thermoplastic synthetic wood pulp fibers to each other and to other fibers in the absorbent layer.
