Abstract: The present invention relates to absorbent articles such as diapers, adult incontinence garments, and feminine hygiene products. The present invention further relates to such absorbent articles having outer coverings designed to provide breathability and promote more healthy internal environmental conditions for the wearer. 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.

Abstract: 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.
