  • Patent number: 6452062
    Abstract: Composite nonwoven material through which liquid can pass at a high speed and having an excellent resistance to rewetting and fluffing. The material comprises at least one first layer (2) of combed-type fibres and a second layer (3) of combed-type fibres, the fibres of the first layer having a denier greater than that of the fibres of the second layer, the layers being joined to one another by needling. Application to absorbent sanitary articles.

  • Patent number: 6204210
    Abstract: A composite nonwoven material having two external layers, formed of body fluid permeable nonwoven material, between which is arranged a synthetic fiber lap which is permeable to body fluids. The external layers are assembled between each other by thermal fusion according to a pattern forming a network of points and a central area of perforations. The composite nonwoven material can be used to make absorbent hygienic articles.

  • Patent number: 6045545
    Abstract: A disposable absorbent article of hygiene includes an absorbent pad disposed between an outer support sheet and an inner cover sheet and has two elasticized side flaps fastened to the cover sheet along the lengthwise edges of the article. Each flap is fastened to the cover sheet over the length of the article by a proximal portion of the flap positioned on an inner side of the absorbent pad, and is folded along the lengthwise direction. The flap is also fastened to the cover sheet in the folded state at end regions of the article so that a distal edge of the flap overlaps the proximal edge over the length of the article, and remains unattached in a region between the end regions to form a pouch.

  • Patent number: 5908412
    Abstract: A coated non-woven material, method of making such material, and disposable absorbent hygiene article are disclosed. The coated non-woven material comprises a base layer made of a non-woven web of fibrous material and at least one layer of a thermoplastic film. The peel strength of the material is equal to or below 98.times.10.sup.-3 kN/m, as measured according to the NFT 76-112 standard, wherein the peeling angle is specified at 180.degree. and the pull speed is specified at 200 mm/mn. In one embodiment, the coated non-woven material is incorporated into a disposable diaper as a liquid-impervious backsheet.

  • Patent number: 5879344
    Abstract: A composite nonwoven material includes a layer made of a nonwoven material which is permeable to body fluids and a sheet of carded synthetic fibers permeable to body fluids. The carded fiber sheet is bonded to the nonwoven layer solely by needling. An absorbent article of hygiene also includes the composite nonwoven material.

  • Patent number: 5843064
    Abstract: Multilayer nonwoven material which has a high rate of drying out, improved rate of entry of, or break-through time by, body fluids and good diffusion of the body fluids in the plane of the layers. The multilayer nonwoven material comprises at least two superposed layers (1, 2) of natural or synthetic textile fibers, joined together, the fibers of the successive layers having a denier decreasing progressively, in a given direction, from one successive layer to the other.Application as surface webs for absorbent articles of hygiene.
