    摘要: Nonwoven fabrics and methods for making the same are described, wherein the fabrics comprise two or more propylene-based elastomers in combination with one or more propylene-based thermoplastic polymers. Specifically, the first propylene-based elastomer comprises at least 7% by weight ethylene or non-propylene alpha-olefin units, the second propylene-based elastomer comprises less than 7% by weight ethylene or non-propylene alpha-olefin units, the first and second propylene-based elastomers each have a heat of fusion less than 80 J/g, and the propylene-based thermoplastic polymer has a heat of fusion greater than 80 J/g.
