  • Patent number: 4846813
    Abstract: A fluid absorbent article, comprising an absorbent web expandable upon fluid absorption and joined to a topsheet of fluid impervious material having a plurality of tapered passages therein, each open at its respective base and apex, and oriented with its base in the plane of the topsheet and its apex disposed in an interior portion of said absorbent web, such that fluid contacting the topsheet, surface tensionally enters the tapered passages at the bases thereof for passage therethrough to exit at the apexes thereof into the absorbent web, whereupon expansion of the absorbent web in proximity to the tapered passages compressively affects closure thereof to sealingly retain the fluid in the absorbent web.

  • Patent number: 4783231
    Abstract: A fibrous web comprising fibers which have been differentially cooled to provide a crimped fiber conformation thereto and then thermally relaxed to a sufficient degree to at least partially decrimp the fibers and increase the loft and decrease the density of the web. Also disclosed is a process for forming a web of such type, comprising the steps of forming a web of fibers, bonding the fibers to form a bonded web, differentially cooling the fibers to provide a crimped fiber conformation thereto, and thermally relaxing the fibers to a sufficient degree to at least partially decrimp the fibers and increase the loft and decrease the density of the web, wherein the differential cooling step preferably is carried out prior to bonding of the fibers to form the bonded web and the thermal relaxing step is carried out after bonding of the fibers to form such web.

  • Patent number: 4761322
    Abstract: A laminated fibrous web comprising: a first fibrous layer; and a second fibrous layer bonded to and of lower density than the first fibrous layer; wherein fibers in the second fibrous layer are less bonded to one another, than fibers in the first fibrous layer are bonded to one another; and wherein the first and second fibrous layers are less bonded to each other than fibers in the first fibrous layer are bonded to one another.

  • Patent number: 4610685
    Abstract: A fibrous web, such as a nonwoven liquid-pervious fibrous web, has reinforced marginal portions and an unreinforced medial portion, the fibers of the reinforced marginal portions being at least partially thermally fused or embedded within a cured bonding medium. A process for forming reinforced marginal portions on a fibrous web includes the steps of passing said fibrous web through a pair of nip rollers having heated marginal surface portions and at least partially thermally fusing fibers of the marginal portions, but not the medial portion, of the fibrous web. Alternatively, the method comprises applying a curable medium to the marginal portions of the fibrous web, but not to the medial portion, and curing the curable medium to embed the fibers of the marginal portions within the cured medium.
