Abstract
A multi-layer, fluid transmissive structure is provided that comprises first and second fiber layers each comprising a plurality of polymeric fibers bonded to each other at spaced apart contact points. The polymeric fibers of these fiber layers have diameters greater than one micron and collectively define interconnected interstitial spaces providing tortuous fluid flow paths through the first and second fiber layers. The structure also comprises a plurality of nanofibers disposed intermediate at least a portion of the first fiber layer and at least a portion of the second fiber layer.
