Abstract: A high loft, low density, nonwoven fibrous web is provided comprising a plurality of irregularly arranged, intersecting, overlapping, mechanically interengaged, loosely assembled fibers including both thermoplastic synthetic wood pulp fibers and other fibers, segments of the thermoplastic synthetic wood pulp fibers being heat fused at a plurality of junctures with segments of other thermoplastic synthetic wood pulp fibers and with segments of fibers of other types, with additional binder distributed throughout the web.The web is prepared by air-laying a blend of thermoplastic synthetic wood pulp fibers and other fibers applying heat without pressure to the air-laid blend to fuse at least some of the thermoplastic synthetic wood pulp fibers to each other and to some of the other fibers to form a self-supporting fibrous web, introducing a latex binder into the web and drying and curing the binder.

Abstract: An absorbent article, such as a disposable diaper, is disclosed which includes a moisture permeable facing layer, a backing layer, and an absorbent layer disposed between said facing and backing layers and including at least one pocket containing a uniform admixture of discrete superabsorbent particles and discrete introfying particles.

Abstract: A catamenial device such as a tampon, a sanitary napkin or the like, is disclosed which includes an absorbent layer having at least one pocket containing a uniform admixture of discrete superabsorbent particles and discrete introfying particles.

Abstract: 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.

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.

Abstract: A high loft, low density, nonwoven fibrous material is provided comprising two layers of irregularly arranged, intersecting, overlapping, mechanically interengaged, loosely assembled fibers, one of the layers including thermoplastic synthetic wood pulp fibers at least in the portion thereof at the interface to the other layer, at least some of the thermoplastic synthetic wood pulp fibers in the one layer being in contact with and fused with segments of fibers of said other layer.The material is produced by air-laying the aforementioned layers successively so that some thermoplastic synthetic wood pulp fibers in one layer are in contact with some fibers in the other layer, and then applying heat without pressure to fuse and bond at least some of the thermoplastic synthetic wood pulp fibers in one layer to fibers in the other layer.

Abstract: 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.

Abstract: A disposable absorbent pad such as a diaper, sanitary napkin, underpad, surgical dressing or wipe, and the like, is made from a flexible, body fluid-impermeable backing sheet, a layer of absorbent material on the backing sheet, and a soft, body fluid-permeable facing sheet which overlies the absorbent material. The facing sheet is a non-woven, open but interconnected network of oriented thermoplastic polymer fiber elements having a mean denier of not more than 3. In addition to being useful as a separate entity, the absorbent pad of this invention can also be incorporated into a disposable or limited use garment as an integral part thereof.
