Abstract: Absorbent structures having a wetlaid fluid acquisition/distribution layer with an average dry density of less than about 0.30 g/cc, an average density upon wetting with 1.0% NaCl aqueous solution of less than about 0.20 g/cc, and an average dry basis weight from about 0.001 to about 0.10 g/cm2; and a fluid storage layer positioned beneath the aquisition/distribution layer comprising at least about 15% superabsorbent material. The fluid acquisition/distribution layer comprises from about 50% to 100% chemically stiffened cellulosic fibers and from 0% to about 50% binding means.

Abstract: Se describen estructuras absorbentes que comprenden una primera capa, una segunda capa yuxtapuesta en relacion de frente con la primera capa, en donde por lo menos una de capas es permeable al fluido. Estas estructuras también tienen una region continua entre las capas primera y segunda que comprenden un polímero formador de hidrogel que está distribuido de manera sustancialmente uniforme a todo lo largo de la region. La region continua circunda al menos parcialmente zonas multiples separadas entre las capas, cuyas zonas están sustancialmente libres del polímero absorbente formador de hidrogel. Las capas primera y segunda están unidas juntas de tal manera que el polímero absorbente formador de hidrogel está sustancialmente inmovilizado cuando está en un estado seco, preferiblemente en los sitios dentro de una pluralidad de las zonas. Preferiblemente, el polímero formador de hidrogel tiene permeabilidad de gel relativamente elevada, tal queéste forma una capa de transportacion de fluido continua de gel.

Abstract: Relatively thin, collapsed, i.e. unexpanded, polymeric foam materials that, upon contact with aqueous body fluids, expand and absorb such fluids, are disclosed. A process for consistently obtaining such relatively thin, collapsed polymeric foam materials by polymerizing a specific type of water-in-oil emulsion, commonly known as High Internal Phase Emulsions or "HIPE", is also disclosed.

Abstract: Absorbent article (20) having a containment assembly (22) comprising an absorbent core (28) between the top sheet (24) and the back sheet (26). The crotch region has a fluid storage capacity of 49%, pref. 41%, most pref. 23% of the total core ultimate storage capacity, and has a high flux liquid distribution material having a flux at 12.4 cm ranging from >0.075 g/cm2/sec to >0.15 g/cm2/sec. The core may comprise natural fibres such as wood pulp or cellulosic fibres, or synthetic fibres such as surfactant- or silica-treated fibres derived from polyolefins, polyacrylics, polyamides, polystyrenes, polyurethanes, etc.. The fibres may be chemically stiffened, twisted and curled. Alternatively, open-celled absorbent polymeric foam materials derived from HIPE-derived foams may be used or super absorbent polymers may be used.
