Abstract

Bicomponent fibers, methods of forming bicomponent fibers and articles formed from bicomponent fibers are described herein. The bicomponent fibers generally include a sheath component and a core component, wherein the sheath component consists essentially of a first metallocene polypropylene and the core component consists essentially of a second metallocene polypropylene.
