Abstract
Nonwoven fibrous webs include elastic filaments such that the web as a whole exhibits elastic properties when stretched. The webs include a multiplicity of nonwoven fibers and at least one elastic filament entangled with at least a portion of the nonwoven fibers to form a self-supporting, cohesive, elastic nonwoven fibrous web. Methods of making such elastic nonwoven fibrous webs using hydro-entanglement, and uses of such webs to form articles are also described.
