  • Patent number: 6027483
    Abstract: A web material which exhibits an elastic-like behavior along at least one axis when subjected to an applied and subsequently released elongation. The web material includes a strainable network having at least two visually distinct regions of the same material composition. The first region undergoes a molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the web material is subjected to an applied elongation in a direction substantially parallel to the axis of elongation.

  • Patent number: 5968029
    Abstract: The present invention is directed to a macroscopically three-dimensional formed substrate including a first boundary zone having a first surface pathlength and a second boundary zone having a second surface pathlength. The first and the second surface pathlengths are preferably measured when the formed substrate is in a relaxed condition. The substrate also includes an elongated zone located at least partially between the first boundary zone and the second boundary zone. The elongated zone comprises incrementally stretched regions which result in the elongated zone being elongated in a first direction of elongation and having a third surface pathlength measured when the formed substrate is in the relaxed condition. The third surface pathlength is greater than either the first pathlength or the second pathlength such that the substrate takes on a macroscopic three-dimensional configuration when the backsheet is in a relaxed condition.

  • Patent number: 5382245
    Abstract: The present invention provides absorbent articles, especially sanitary napkins, containing a fluid transport layer. In-use, the transport layer directs menses to a storage layer, thereby minimizing product failure and staining of undergarments. The transport layer can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges. Preferably, the transport layer is a layer of fibers having external capillary channels.

  • Patent number: 5356405
    Abstract: Absorbent articles, especially sanitary napkins, contain fibers with intra-fiber capillary channels. In-use, the capillary channel fibers direct menses to a storage layer, thereby minimizing product failure and staining of undergarments. The capillary channel fibers can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges.

  • Patent number: 5185052
    Abstract: Disclosed is an apparatus for longitudinally pleating a moving lamina. The apparatus features a curved axis roll having a stationary axis circumscribed by a rotating sleeve with a plurality of circumferentially oriented grooves in the rotating sleeve. The pleats are produced by the intermeshing of the lamina with the grooves of the rotating sleeve. Preferably a complementary curved axis roll having lands which interdigitate with the grooves of the first roll is used in conjunction with the first curved axis roll.The apparatus preferably further comprises a third curved axis roll disposed upstream of the first curved axis roll to substantially equalize the paths of travel of any points on the moving lamina by compensating for differences in the paths of travel between the edges and centerline of the lamina.

  • Patent number: 4772444
    Abstract: A method for hydraulically deforming a web of polymeric film while the film is supported on a moving forming structure to produce a novel microbubbled substantially fluid-impervious web exhibiting substantially the same consumer preferred soft and silky tactile impression and reduced noise generation levels heretofore only achievable in microapertured, and hence substantially fluid pervious polymeric webs. In a particularly preferred embodiment, the microbubbled polymeric web exhibits a fine-scale pattern of discrete mushroom shaped surface aberrations, each of said surface aberrations having its amplitude oriented substantially perpendicular to the surface in which the surface aberration originates. The method may also be utilized to produce fluid pervious microapertured webs which are known in the art. Apparatus for producing microbubbled and/or microapertured webs either in "planar" or "macroscopically expanded" form are also disclosed.

  • Patent number: 4447373
    Abstract: A process of making a hollow article from polymeric material is taught. The article is molded in two parts. The two parts are caused to remain in their respective exterior molds. If the hollow article is to be filled with a desired material, a measured amount of filler material is added to one of the formed parts. The exterior molds are brought into opposed position and sealing relationship. The space between the exterior molds is purged with a purging gas and subjected to a partial vacuum. The exterior molds are then closed and subjected to a clamping pressure to join the part halves together and remove flash from the joint. Portions at least of the exterior molds are heated and then cooled. The exterior molds are then opened, and the finished filled article is removed therefrom.

  • Patent number: H1511
    Abstract: The present invention provides absorbent articles, especially sanitary napkins, containing a flow regulator positioned between the topsheet and the absorbent core. In-use, fluid deposited on the topsheet is internally moved in the longitudinal direction by the flow regulator before being released to the absorbent core. By moving substantial amounts of fluid in the longitudinal direction the flow regulator provides a more effective use of the absorbent core.
