Abstract
Abstract The present invention provides a composite elastic necked-bonded material including at least one necked material joined to at least one elastic sheet. The composite elastic necked-bonded material is stretchable in a direction generally parallel to the direction of constriction or necking of the necked material. Also disclosed is a method of producing a composite elastic necked-bonded material by necking a neckable material and then joining the necked material to an elastic sheet.
