Abstract: A fibrous structure suitable for use as a battery separator is described. The fibrous structure may include a plurality of plies or layers. Each ply or layer serves to provide a barrier function and an absorbent function, such that the multilayer fibrous structure is suitable for use as a battery separator, for example, an alkaline battery separator.

Abstract: A composite filter media of a nanofiber layer that includes nanofibers formed from non-polar, non-conductive thermoplastic polymers using a solution spinning process to form the nanofibers directly onto a conductive layer is presented, along with the associated methodology for making such media. The conductive layer includes at least about greater than about 5 wt. % conductive fibers, Z-directional conductivity and a uniform surface conductivity of at least about 10?7 microsiemens.

Abstract: The invention provides an improved facing (1) for a gypsum wallboard (22) that has a single layer (2) of nonwoven substrate (3) having about 40-80% of glass staple fibers (4) and about 50-15% of polymeric fibers (5), and wherein the ratio of the diameters of the glass fibers (4) and the polymeric fibers (5) is between about 1.5-3:1. A hydrophilic binders is disposed in the substrate (3) in the form of a porous film (10) that extents throughout the substrate (3) so as to provide the substrate, having only the binder therein, with a porosity of between about 150-450 cfm/sq. ft. A hydrophobic, polymeric coating (6) is applied to an upper front face (7) of the substrate (3), wherein 90% of the coating (6) lies within a distance from the front face (7) of the substrate (3) that is no more than 50% of the thickness (T) of the substrate (3).
