Abstract
The present invention provides nonwoven webs comprising multicomponent nanocomposite fibers that enable the nonwoven webs to possess high extensibility. The multicomponent nanocomposite fibers comprise two or more components. Each component comprises a polymer composition and at least one component comprises a nanoparticles composition. The nonwoven webs comprising the multicomponent nanocomposite fibers have an average elongation at peak load which is greater than the average elongation at peak load of comparable nonwoven webs without nanocomposite fibers.
