    摘要： The present invention relates to an absorbent laminate structure, and disposable absorbent article incorporating the structure, wherein first and second absorbent matrices comprising particulate superabsorbent polymeric material and filamentary adhesive are arranged between two outer substrate layers. The relatively porous, intermediate or central substrate layer, positioned between the absorbent matrices, promotes liquid transport within the laminate structure.

    摘要： The present invention relates to a layered absorbent structure in the form of a laminate including liquid storage layers comprising particulate superabsorbent material and adhesive fibers. Notably, the absorbent structure includes a wicking layer positioned between the liquid storage layers, with the wicking layer desirably acting to improve fluid spreading and rewet performance of the absorbent structure. The wicking layer preferably comprises airlaid cellulosic fibrous material such as wood pulp, and may optionally include superabsorbent polymer. A bonding pattern of the wicking layer is oriented to enhance wicking and rewet performance.

    摘要： An absorbent structure including a composite absorbent laminate is disclosed, with the structure suitable for use in disposable absorbent products such as for infant or incontinence care. Notably the laminate comprises discrete acquisition cells each comprising particles of preferably cellulosic absorbent material. The absorbent structure further comprises particulate superabsorbent polymer which can either be blended with the particulate discrete acquisition cells in the absorbent laminate, or provided in a separate absorbent layer of the absorbent structure. The discrete acquisition cells desirably generate free volume for rapid capillary absorption in an ultra-thin absorbent structure.

    摘要： An absorbent structure including a dryness layer laminate is disclosed, with the structure suitable for use in disposable absorbent products such as for infant or incontinence care. The dryness layer laminate is positioned adjacent an associated absorbent core, between the absorbent core and the wearer, for enhancing surface dryness and comfort for the wearer. The dryness layer laminate comprises adhesive fibers or filaments, and particulate superabsorbent, and is configured to permit liquid to pass through the laminate to the associated absorbent core, while acting to remove liquid from the surface of the absorbent structure positioned adjacent to the wearer.

    摘要： The present invention is directed to a method of forming a laminate absorbent structure, and a resulting package containing a single continuous running web of the laminate material. Notably, formation of the material is effected by blending a curtain of adhesive fibers with a curtain of particulate material, and depositing the mixture on a moving substrate, preferably provided in the form of a tissue layer. A second substrate, also preferably comprising a tissue layer, is applied on top of the deposited mixture, and pressure applied to form the laminated structure. Notably, attendant to packaging of the laminated material, adjacent layers of the material tend to nest into one another, to form a sandwich in which the density of the material in the package is more than 1.5 times the density of the material after its removal from the package.
