Abstract

A web material which exhibits an elastic-like behavior along at least one axis when subjected to an applied and subsequently released elongation. The web material includes a strainable network having at least two visually distinct regions of the same material composition. The first region undergoes a molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the web material is subjected to an applied elongation in a direction substantially parallel to the axis of elongation.
