  • Patent number: 11744748
    Abstract: The present disclosure relates to absorbent garments having a dryness layer that can comprise one or more laminates and one or more channels to facilitate liquid acquisition and retention. Laminate(s) can include an absorbent lamina disposed between substrate laminae, each comprising tissue and/or a nonwoven. Some dryness layers can have a folded laminate that defines a longitudinally-extending channel. Some dryness layers can have two or more laminate strips that are laterally spaced apart along a width of the dryness layer such that one or more longitudinally-extending channels are defined therebetween.

  • Patent number: 10092674
    Abstract: 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.

  • Patent number: 6913718
    Abstract: A method for formation of shaped components such as shaped absorbent cores, for disposable absorbent articles, contemplates that a relatively wide web of material be provided from which the components are cut. The web of material is longitudinally slit to form a plurality of subdivided webs each having shaped components arranged in serial relationship. The shaped components of adjacent ones of the subdivided webs are nested with each other, that is, a line extending longitudinally of the web extends through the components of adjacent subdivided webs. Efficient formation is facilitated by collecting the marginal portions of the web of material, and at least partially recycling the collected portions for formation of the wide web.

  • Publication number: 20050118916
    Abstract: In accordance with the present invention, a composite absorbent structure is formed by air laying an absorbent core comprising cellulosic fibers, typically wood pulp fibers. The absorbent core may include superabsorbent polymeric material (SAP), for enhanced liquid absorption and retention. The present invention contemplates that a nonwoven fabric layer be provided which comprises polymeric fibrous material, either in staple length or filamentary form. A composite material is formed in which the cellulosic fibers are hydrogen bonded to form an absorbent core and the nonwoven fabric layer is laminated to this hydrogen bonded layer, without adding additional non-cellulosic bonding agents (the cellulosic fibers themselves act as their own bonding agents) either to the cellulosic layer or between the cellulosic layer and the nonwoven.

  • Publication number: 20050010184
    Abstract: A disposable absorbent article partially defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, includes a topsheet layer, a backsheet layer, and an absorbent core disposed between the topsheet and the backsheet. The disposable absorbent article also has a pair of side wall structures each having a pair of oppositely positioned end portions. A first side wall structure extends generally longitudinally between the core and one of the side edges and the other side wall structure extends generally longitudinally between the core and the other side edge. Further, an end strip constructed from an elastic material is positioned substantially adjacent each one of the end edges, and extends laterally between the side edges.
