International ClassB32B 027/14AbstractThe 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.Field of SearchWrinkled, creased, crinkled or crepedSpot bonds connect components MICROFIBER (LESS THAN 100 MICRON DIAMETER) Synthetic resin or polymer Three or more layers Cellulosic (e.g., wood, paper, cork, rayon, etc.) MATERIAL DESIGNED TO BE RESPONSIVE TO TEMPERATURE, LIGHT, MOISTURE, ETC.
