A nonwoven fabric with spun filaments fused together made from a composition comprising: (a) 50% to 90% by weight, based on the total weight of the composition, of a propylene based elastomer comprising 5% a 35% by weight of units derived from alpha-olefin and having a heat of fusion, determined by DSC, of less than 80 J / g and an MFR of 5 to 100dg / min (ASTM D-1238, 2.16 kg at 230 ° C) ; (b) from 2% to 50% by weight, based on the total weight of the composition, of a propylene-based polymer thermoplastic characterized by an MFR (ASTM D-1238, 2.16 kg at 230 ° C) from 3 to 300 dg / min, at least 97% of the propylene-based polymer units derived from the polymerization of propylene and a heat of fusion, determined by DSC, greater than 140 J / g; and (c) a large MFR polypropylene thermoplastic resin having an MFR (ASTM D-1238, 2.16 kga 230 ° C) greater than 400 dg / min and having at least 90% of the polymer units derived from propylene which is derived from the polymerization of propylene and, optionally, a hydrocarbon resin as a touch improver; and (d) optionally a sliding aid. |
