Abstract:
1. A non-woven fabric made from a composition prepared by combining: (a) from 10 to 40 percent by weight, based on the weight of the total composition, of a first propylene-based polymer blend prepared by combining (i) 90 to 70 wt %, by weight of the first propylene-based polymer blend, of a first propylene-based elastomer having an M (b) from 90 to 60 percent by weight, based on the weight of the total composition, of a second propylene-based polymer blend prepared by combining (i) 90 to 70 wt %, by weight of the second propylene-based polymer blend, of a second propylene-based elastomer having an M where the propylene-based elastomers comprise from about 5% to 35% by weight units derived from ethylene or non-propylene alpha-olefin, the propylene-based elastomer possessing 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, and wherein the propylene-based thermoplastic resin has a T wherein the first and second propylene-based polymer blends form a composition that has a bimodal molecular weight distribution.
