Abstract:
A nonwoven fabric made from a composition comprising (a) a propylene-based elastomer characterized by including from about 5% to about 35% by weight units deriving from alpha-olefin and a heat of fusion, as determined by DSC, of less than 80 J/g, (b) a propylene-based thermoplastic polymer characterized by an MFR (ASTM D-1238 2.16 kg @ 230° C.) of from about 3 to about 300 dg/min, and a heat of fusion, as determined by DSC, of greater than 80 J/g, and (c) a feel modifier selected from the group consisting of (i) a high-MFR thermoplastic resin having an MFR (ASTM D-1238 2.16 kg @ 230° C.) in excess of 400 dg/min, (ii) a hydrocarbon resin, (iii) a polyolefin wax, (iv) a functionalized hydrocarbon resin, (v) a functionalized polyolefin, and (vi) a combination of two or more of the foregoing feel modifiers, and (d) optionally a slip aid.
