  • Patent number: 6989005
    Abstract: A disposable absorbent article suitable for absorbing and retaining aqueous body fluids includes a backsheet that is substantially liquid impervious except at a discontinuity therein and an absorbent core between the backsheet and a topsheet. The absorbent core includes a non-removable component and a removable and replaceable component in fluid communication with the non-removable component. Access for the removal and replacement of the removable component is provided by the discontinuity in the backsheet. The replaceable absorbent core component may be removed and a like component may be substituted in place of the removed component without removal of the absorbent article from the wearer.

  • Patent number: 6909028
    Abstract: A thermally stable microporous breathable film is provided comprising at least 35% filler, by weight of the filled-film, and a thermoplastic polymer blend of a first polyethylene polymer and a second polyethylene polymer. The first polyethylene polymer comprises 30%-70% by weight of the polymer blend and can have a density between about 0.86 g/cm3 and 0.89 g/cm3 and the second polyethylene polymer can have a density between about 0.90 g/cm3 and 0.92 g/cm3. The filled-film can be uniaxially or biaxially oriented to form a microporous film and/or film laminate having good body conformance and which retains a high WVTR at 37° C. and above.

  • Patent number: 6881876
    Abstract: The invention relates to a material structure for use in absorbent articles, and an absorbent article comprising such a material structure. The material structure (1) comprises a liquid-pervious cover layer (2), a liquid-impervious cover layer (3), and an absorbent structure (4, 4?) enclosed between the cover layers (2, 3). Thereby, the absorbent structure (4, 4?) comprises polylactide fibres or filaments, the properties of which contributing to a rapid acquisition of liquid through the liquid-pervious cover layer (2) for absorption into the absorbent structure (4, 4?) also when the material structure (1) is subjected to repeated wettings. The invention can advantageously be applied within the field of absorbent hygiene articles, such as different types of diapers and incontinence guards, sanitary napkins, pantyliners, and the like.

  • Patent number: 6802932
    Abstract: A method for manufacturing an absorbent article including: a topsheet formed from a nonwoven fabric; a backsheet; and a cushion layer disposed between the topsheet and the backsheet is achieved by applying heat to a cushion layer unwound from a material roll to restore the bulkiness of the tissue layer, blowing air into the cushion layer for rapid cooling after the application of heat to maintain the restored bulkiness of the cushion layer, and laminating the topsheet, cushion layer, and the backsheet onto each other.

  • Patent number: 6781027
    Abstract: A nonwoven surge material for personal care products, which is a nonwoven fabric made of a homogeneous blend of large and small denier fibers. The small or first denier fiber preferably has an average denier less than 2, is at least 3 denier less than the second or larger fiber and the large or second denier fiber has an average denier between 4 and 15. The nonwoven fabric is a mixture of these fibers in amounts of from 25 to 75 weight percent of each type of fiber. The fabric may have a basis weight between 30 and 200 gsm. The first denier fiber may be a bicomponent fiber which may be a sheath/core polyethylene/polypropylene bicomponent fiber. The second denier fiber may be made from a polyester. It is also possible that the fibers have a hydrophilic treatment added to their surface to increase their hydrophilicity.

  • Patent number: 6761955
    Abstract: Disclosed is an absorbent article including a topsheet, a backsheet and an absorbent core positioned between the topsheet and the backsheet, and having leakage-preventing side walls on a liquid-receiving side of the article. The leakage-preventing side walls extend in a longitudinal direction of the article and lie opposite one another in a width direction of the article. At least a liquid-receiving face of each leakage-preventing side wall is made of a fibrous sheet that contains hydrophobic fibers thermally bonded to one another and hydrophilic fibers shorter than the hydrophobic fibers. At least a part of the hydrophilic fibers form aggregates which are dispersed in the fibrous sheet and are bonded to the hydrophobic fibers.

  • Publication number: 20040133177
    Abstract: The present invention is directed to absorbent articles comprised of one or more components exhibiting an improved barrier to basis weight performance. The improved barrier performance of the aforementioned absorbent article components is a result of supplying a strong and durable nonwoven substrate layer followed by deposition of a nano-denier, essentially continuously filament barrier layer onto the nonwoven substrate layer thereby providing absorbent articles that exhibit enhanced barrier performance in comparison to conventional absorbent articles.
