Abstract
A non-woven fabric made from a composition prepared by combining a first propylene-based polymer blend, where the first polymer blend is prepared by combining a propylene-based elastomer with a propylene-based thermoplastic resin and where the first blend has an MFR (ASTM D-1238 2.16 kg @ 230° C.) equal to or less than 50 dg/min, with a second propylene-based polymer blend, where the second polymer blend is prepared by combining a propylene-based elastomer with a propylene-based thermoplastic resin and where said second blend has an MFR (ASTM D-1238 2.16 kg @ 230° C.) greater than 50 dg/min, where the propylene-based elastomers comprise from about 5% to 35% by weight units derived from ethylene or non-propylene alpha-olefin and have a heat of fusion, as determined by DSC, of less than 80 J/g, and where the propylene-based thermoplastic resins have a heat of fusion, as determined by DSC, equal to or greater than 80 J/g.
