US Patent 8168550 - Extensible nonwoven webs containing monocomponent nanocomposite fibers

This patent from Procter Gamble teaches incorporation of nanofibers into nonwoven webs to achieve absorbent articles such as diapers and wipes that are softer and more extensible. Claim 1 reads:

1. A nonwoven web comprising monocomponent nanocomposite fibers, the nanocomposite fibers comprising:

a) a polymer composition; and

b) a nanoparticles composition, wherein the nonwoven web has an average elongation at peak load that is greater than the average elongation at peak load of a comparable web without nanocomposite fibers.
