摘要： A moisture vapor permeable, substantially liquid impermeable composite sheet material comprising a fibrous substrate and a moisture vapor permeable thermoplastic film layer. The moisture vapor permeable film has an average thickness of less than 25 microns, a peel strength of at least 0.1 N/cm, a dynamic fluid transmission of less than about 0.75 g/m2 when subjected to an impact energy of about 2400 joules/m2, a hydrostatic head of at least 60 cm, and a moisture vapor transmission rate, according to the desiccant method, of at least 2800 g/m2/24 hr. The moisture vapor permeable film is preferably comprised of at least about 50% by weight of polymer selected from the group of block copolyether esters, block copolyether amides, polyurethanes, polyvinyl alcohol, and combinations thereof. A method for making such a sheet material is also provided.

摘要： Incorporation of an encapsulated nucleant made from an encapsulant polymer and a nucleant, wherein the encapsulant polymer is selected from linear low density polyethylene, high density polyethylene, and polypropylene, into polyoxymethylene compositions results in a decrease in the center line porosity of polyoxymethylene extruded stock shape parts, without also reducing the rate of extrusion. The compositions are especially useful for extrusion into stock shape parts, such as rod, slab, sheet, and tube stock, which are used for machined parts (like artificial limbs and complex gears), die cut parts (like washers and gaskets), and control cable inners.

More specifically, the present invention provides an absorbent article comprising (a) a topsheet; (b) a backsheet; and (c) an absorbent core located between the topsheet and the backsheet; wherein the backsheet comprises a non-porous, substantially fluid impermeable, moisture vapor permeable composite sheet material. Preferably, the composite sheet material is oriented such that the film layer of the composite sheet material faces toward said absorbent core. Where the film layer of the composite sheet comprises a substantially hydrophilic elastomer film layer, the substantially hydrophilic elastomer film is preferably located in contact with the fibrous substrate. Where the film layer of the composite sheet comprises a multiple layer film with a substantially hydrophilic elastomer film layer and a substantially hydrophobic elastomer film, the substantially hydrophilic elastomer film is preferably located between the substantially hydrophobic elastomer film and the fibrous substrate. In another embodiment, the film layer may further comprise a third film layer comprising a substantially hydrophobic elastomer film located between the substantially hydrophilic elastomer film and the fibrous substrate. The absorbent article may comprise a disposable diaper.
