  • Patent number: 5626571
    Abstract: A nonwoven that is exceptionally soft yet sufficiently strong for use in absorbent articles is disclosed. The soft, strong nonwoven includes fibers comprising polyethylene, at least a portion of which are consolidated. The soft, strong nonwoven has a cross-machine direction tensile strength of at least about 300 g/in and a cross-machine direction elongation at break of at least about 40%.The soft, strong nonwoven is preferably formed by permanently stretching an inelastic base nonwoven in the cross-machine direction. The preferred base nonwoven has certain properties which allow it to have sufficient strength after stretching, while being exceptionally soft, such that the resultant permanently stretched, soft, strong nonwoven is particularly suitable for use as a topsheet or a back sheet component in disposable absorbent articles.

  • Patent number: 5624425
    Abstract: A disposable absorbent article that effectively prevents the leakage of body fluids beyond its confines. The article of the present invention comprises a body having a fluid-impermeable backsheet, an intermediate, fluid-absorbing core, and a fluid-permeable topsheet. A pair of leg cuff assemblies is attached to the body. Each assembly comprises a cuff standing portion and a cuff base portion. The assemblies are composed of two hydrophobic nonwoven layers. A first layer is composed of a spunbonded web and a second layer is composed of a meltblown fiber. The first layer extends from the free, unattached end of the cuff standing portion to the distal edge of the article defining the leg opening. The second layer is provided where needed and in weights as needed to provide maximum assembly hydrophobicity with a minimum use of material. This construction allows the cuff assemblies to form fluid-impermeable dams which prevent passage of body fluid beyond the article along its leg hole sides.

  • Patent number: 5624427
    Abstract: The present invention provides a refastenable fastening device including female fastening component preferably comprising a base web and an engaging layer. The base web comprises a structural elastic-like film (SELF) web and is joined to the engaging layer which comprises a plurality of filaments or a nonwoven web. The SELF web exhibits an elastic-like behavior in the direction of elongation without the use of added elastic materials. The SELF web includes a strainable network having at least two distinct regions comprised of the same material composition. The first region is oriented substantially parallel to an axis of elongation such that it will undergo a molecular-level deformation in response to an applied axial elongation in a direction substantially parallel to the elongation axis before a substantial portion of the second region undergoes any substantial molecular-level deformation.

  • Patent number: 5613964
    Abstract: A sanitary napkin assembly comprises a plurality of thin, substantially planar, individual sanitary napkin units which are arranged in a stack so that their planar faces are adjacent. Each individual napkin unit is removably attached to the one or two individual, units which are adjacent to it. Each individual napkin unit comprises a sheet or layer for receiving, absorbing, and containing; body fluids secreted by the user, and a water-proof barrier sheet or layer for precluding, leakage of absorbed fluids to adjacent units or to the user's clothing. Thin adhesive-tape strips (or other suitable attachment media) are used to permanently attach the fluid-receiving layer to the barrier layer. Similar tape strips (or other suitable attachment media) are used to removably attach individual napkin units to adjacent units, and to removably attach the assembly to an interior portion of the user's undergarment.

  • Patent number: 5607465
    Abstract: A valve for use in a blood vessel, internal to the blood vessel itself, in contact with a blood stream, has a bent flexible wire mesh (1) with elasticity and plasticity so as to be collapsible and implantable remotely at a desired site. The wire mesh (1) is bent into three turns, two end ones (6, 6') and a central one (5), in such a way as to confine a tubular space. The central turn (5) is located at an angle relative to the end turns (6, 6') and mounts a monocusp sail-like valving element (2). A special catheter (12) is used to collapse the flexible wire mesh (1), to implant it remotely at the desired site, and to restore the wire mesh (1) to its original three-dimensional configuration.

  • Patent number: 5599417
    Abstract: An absorbent garment method of manufacture includes supplying a three-dimensional pant body defining a waist opening, two leg openings, and a crotch region. A containment trough formed of liquid impermeable material has a base portion bonded to the crotch region and integral retaining walls positioned transversely outward from the base portion. The retaining walls are freestanding from the pant body and include elastic members so as to define freestanding, elasticized flaps. An absorbent structure and liner are disposed between the elasticized flaps. To retard liquid movement away from the absorbent structure, the liner is wrapped around the side edges and partly beneath the absorbent structure. Further, an inwardly-directed face of each flap has a first Wicking Value while the liner has a second Wicking Value that is at least 2 times greater than the first Wicking Value on a gram per gram basis.

  • Patent number: 5599335
    Abstract: Absorbent members useful in the containment of body fluids such as urine, that have at least one region containing hydrogel-forming absorbent polymer in a concentration of from about 60 to 100% by weight and providing a gel-continuous fluid transportation zone when in a swollen state. This hydrogel-forming absorbent polymer has: (a) a Saline Flow Conductivity (SFC) value of at least about 30.times.10.sup.-7 cm.sup.3 sec/g; (b) a Performance under Pressure (PUP) capacity value of at least about 23 g/g under a confining pressure of 0.7 psi (5 kPa); and (c) a basis weight of at least about 10 gsm. In addition, the region where this hydrogel-forming absorbent polymer is present has, even when subjected to normal use conditions, sufficient wet integrity such that the gel-continuous zone substantially maintains its ability to acquire and transport body fluids through the gel-continuous zone.
