Abstract: A flexible non-disintegrative absorbent product comprising a water-insoluble substantially non-swelling matrix of a thermoplastic polymer bearing a uniformly dispersed particulate water-insoluble water-swellable organic polymer absorbent. Certain compositions and processes for their preparation as well as article prepared from the products are described.

Abstract: A disposable diaper is disclosed. This diaper includes an absorbent body forming a layer thicker in a crotch area than in the rest area, said thicker layer of the absorbent body defined in the crotch area pressed along both sides thereof, and elastic members located on both sides of the crotch area each made of a relatively wide material.

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: A sanitary napkin comprising an absorbent, a liquid-impervious layer covering the bottom, sides and top edge of the absorbent and a non-woven wrapper fabric covering the absorbent and the liquid-impervious layer, wherein the non-woven fabric has a double layer structure comprising a web layer in which most of the fibers are oriented uniformly and another web layer in which the fibers are randomly arranged.

Abstract: Absorptive devices comprising a facing element, a support element, an absorbent core, and a backsheet. The facing element is a body fluid permeable, unbonded, carded web of resilient, hydrophobic fibers which has been affixed to the supporting element through the means of spaced apart regions of bonding. The supporting element is a body fluid permeable planer sheet compatible with and affixed to the facing element. The absorbent core must absorb and retain body fluids while the backsheet must be impermeable to such fluids. The four elements are superimposed one upon another in the order mentioned and are united in that position to form devices such as disposable diapers, sanitary napkins, incontinent pads and the like.

Abstract: A delaminatable two-ply diaper facing material is provided in which an outer ply, or layer, is made of irregularly arranged, intersecting, overlapping, mechanically interengaged, loosely assembled natural wood pulp fibers and an inner ply, or layer, contains similarly disposed natural wood pulp fibers and thermoplastic synthetic wood pulp fibers having a melting point lower than that of other fibers in the layer, the latter being in contact with and heat fused with other fibers to provide structural integrity to the inner layer, with fibers in both layers being bonded to each other by a water soluble adhesive binder.The material is prepared by bringing together the aforementioned layers, applying heat in the absence of pressure to fuse the thermoplastic synthetic wood pulp fibers in the inner layer to each other and to other fibers, introducing a water soluble adhesive binder into the two layers and then drying and curing the binder.
