Abstract: A fiber or nonwoven and methods for making and using same are provided herein. The fiber or nonwoven can contain at least one primary polypropylene, at least one polyalphaolefin, and at least one propylene-based elastomer. The propylene-based elastomer can have a heat of fusion less than about 80 J/g. The propylene-based elastomer can also include greater than 50 wt % propylene and from about 3 to about 25 wt % units derived from one or more C2 or C4-C12 α-olefins, based on a total weight of the propylene-based elastomer.
