    Abstract: A film that comprises a thermoplastic composition that contains a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains is provided. The film is biaxially stretched in a machine direction and cross-machine direction to form a porous network in the composition. The porous network contains nanopores having a maximum cross-sectional dimension of about 800 nanometers or less. At least a portion of the nanopores are oriented in the cross-machine direction so that the axial dimension generally extends in the cross-machine direction and the cross-sectional dimension generally extends in the machine direction.

    Abstract: A breathable film having a base layer comprising first filler particles and second filler particles dispersed within a biodegradable polymer matrix is provided. The first filler particles constitute from about 25 wt.% to about 75 wt.% of the base layer and the second filler particles constitute from about 0.1 wt.% to about 10 wt.% of the base layer. The ratio of the average size of the first filler particles to the average size of the second filler particles being from about 2 to about 100. The film exhibits a water vapor transmission rate of about 2,000 g/m/24 hours or more and a peak load in the machine direction of about 800 grams-force per inch or more.

    Abstract: The present invention provides a natural fiber knitlike multi-layer composite containing at least one layer of a nonwoven fiber web and at least one layer of an elastomeric material, wherein the nonwoven web layer is joined to the elastic layer at spaced-apart locations and is gathered between said spaced-apart locations. The nonwoven fiber web is fabricated from multicomponent conjugate fibers or filaments that contain at least one polyolefin, and is a spunbond fiber web, staple fiber web or hydroentangled web. The composite exhibit soft, clothlike texture of natural fiber knits as well as highly useful elastic properties.

    Abstract: An apertured, film-coated nonwoven fabric or material and a process for making the film-coated nonwoven fabric or material are provided. A nonwoven material layer is formed and extrusion coated with a polymer film to form a film-coated nonwoven material, the film-coated nonwoven material including a film layer having a thickness not greater than about 0.30 mils. A plurality of apertures may be formed in at least the film layer to form the apertured, film-coated nonwoven material. In alternative embodiments of this invention, a plurality of "peaks" or "cones" may be formed in the film layer having an aperture at a "valley" formed between adjacent peaks or cones.

    Abstract: An elastic nonwoven web is formed from elastic fibers composed of a blend of (1) a styrene-poly(ethylene- propylene)-styrene thermoplastic. elastomeric block copolymer or a mixture of a styrene-poly(ethylene- propylene)-styrene elastomeric block copolymer and a styrene-polyethylene-butylene)-styrene elastomeric block copolymer, and (2) a tackifying resin in which the elastic nonwoven web has a stress relaxation of less than about 30 percent. the blend used to form the elastic nonwoven web and/or elastic fibers may also include a polyolefin and an extending oil.
