摘要： The invention of the present application comprises a high loft, low density, nonwoven fibrous material and method of making the same. The material has good wet strength, softness, abrasion resistance, and liquid absorbency and retention, and is formed of a plurality of irregularly arranged, intersecting, overlapping, mechanically interengaged, loosely assembled fibers including both synthetic and natural wood pulp fibers which are present in different proportions in various regions parallel to the median plane of the material. Segments of said synthetic wood pulp fibers are heat fused with other segments of synthetic wood pulp fibers and with segments of other fibers at a plurality of junctures throughout the fibrous material to form a self-supporting fibrous structure which does not require any additional binder.

摘要： A method is provided for the stabilization of a high loft, low density, air-laid pad of short length fibers by the formation of a thin, reinforcing layer on a surface thereof. The film is formed by first pretreating a surface of the pad with a light spray (at a level not higher than about 15 cc per sq. meter of the pad) of a solution of a coagulating material for a resin dispersion, and then applying the resin dispersion to the pretreated surface and limiting its penetration into the pad by instant coagulation thereof.

摘要： 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.
