Abstract
A composite elastic material including at least one reversibly necked material and at least one elastic sheet joined at least at two locations in which the reversibly necked material is formed from a neckable material which has been treated so that, upon application of a force to extend the necked material to its pre-necked dimensions, the material returns generally to its necked dimensions upon termination of the force. Also disclosed is a process for making a composite elastic material by joining a reversibly necked material to an elastic sheet at least at two locations.
