Including A Nonwoven Fabric Layer Other Than Paper Patents (Class 442/319)
  • Patent number: 5685247
    Abstract: A multi-layer material for use in incontinence products comprises a base layer comprising a needled felt containing not less than 50% by weight polyester fiber, wherein the surface regions of the felt are denser than the central region thereof, which remains substantially unneedled. In addition, a second, multi-ply, layer is provided by a unitary fabric comprising two outer plies of knitted polyester fiber fabric with a ply of monofilament polyester accommodated therebetween. In order to prevent strike-through, furthermore, a barrier layer, e.g. of a polyurethane coated fabric, is also provided, as is also a fourth, skin-contact, layer with a nap finish to provide a comfortable "feel" to the product. Incontinence products made from this material exhibit good absorbency, little or no strike-through and a dry skin effect.

  • Patent number: 5681645
    Abstract: There is provided a laminate material having stretchability and recovery, breathability and barrier properties, and being made from a nonwoven elastomeric web having at least one web of textile material discontinuously adhesively bonded to each side thereof. The laminate material is free of an elastomeric film, the elastomeric web is substantially flat when the laminate is unstretched, and the nonwoven elastomeric web provides recovery to the laminate. The nonwoven elastomeric web is preferably a web of meltblown elastomeric fibers and the other webs may be knits, wovens or scrim materials. These laminates are well suited for infection control products, personal care products and garments.

  • Patent number: 5662991
    Abstract: A biocidal fabric in which a pattern of clusters of biocidal beads are adhered between an air pervious substrate and a cover which may be gas impervious, water-vapor pervious or gas pervious. In the method and appratus for making the fabric, a pattern of hot melt adhesive is applied to the substrate and beads of biocidal material are sprinkled over the adhesive, after which the excess beads are removed. The same pattern of adhesive is applied to the cover and the cover adhesive is brought into contact with the beads on the substrate to complete the fabric.
