Abstract: A breathable multilayer film having a breathable core layer and at least one skin layer is disclosed. The core layer prepared by from a mixture containing a thermoplastic polymer and a particulate filler and the skin layer or layers are prepared from a mixture of at least two incompatible polymers and a polymer which compatiblizes the incompatible polymers. The addition of the compatiblizer in the skin layer improves the film forming consistency. In addition, the core layer contains voids around the particulate filler and the skin layer or layer has cracks or voids, which provides breathability to the multilayer film. Stretching of the film after the layers are coextruded together forms the voids and/or cracks.

Abstract: A highly breathable, stretch-thinned film having enhanced breathability includes a matrix polymer, a particulate filler, and an incompatible polymer that is thermodynamically incompatible with the matrix polymer. The incompatible polymer can be added to the film in the form of laminate waste material.

Abstract: A textile fiber including polypropylene blended with an impact modifier. The impact modifier can be less than 10% by weight of the composition. Examples of suitable impact modifiers include ethylene-propylene-diene-monomer (EPDM), styrene/ethylene-co-butadiene/styrene (SEBS), and styrene-poly(ethylene-propylene)-styrene-poly(ethylene-propylene) (SEPSEP). The textile fiber can be used to form a spunbond fiber, a staple fiber, a multi-fiber yarn, a knit fabric, a woven fabric, or a nonwoven fabric.
