  • Publication number: 20040135286
    Abstract: A method for producing a nonwoven web material having cross-machine direction extensibility in which a nonwoven web is conveyed through a machine which elongates the nonwoven web in a cross-machine direction (CD). The elongated nonwoven web is then necked, forming a cross-machine direction extensible nonwoven web material. The CD extensible nonwoven web material is highly stretchable and is suitable for use in personal care articles, such as diapers, incontinence garments, and feminine care products, as well as other articles, such as wipes, face masks, tissues, bandages and wound dressings.

  • Patent number: 6348258
    Abstract: A breathable film having improved processing properties and reduced cost includes a breathable film-forming layer composition including a matrix polymer, a particulate organic filler, and a compatibilizer. The particulate organic filler is incompatible with the matrix polymer and tends to agglomerate when mixed with the matrix polymer alone. The compatibilizer achieves thermodynamic equilibrium between the matrix polymer and filler within a defined filler particle size range suitable for producing stretched breathable film. The film processes more easily than breathable films containing inorganic fillers, and is less expensive to manufacture.

  • Patent number: 6245401
    Abstract: Unitary films are provided having at least first and second film segments which extend adjacent one another and are permanently joined together. The first and second segments have different compositions whereby the unitary film includes distinct segments having varied physical properties such as, for example, varied levels of high water-vapor transmission rates and/or elasticity. The unitary films and laminates thereof are well suited for use as outer covers in personal care articles and various other barrier articles.
