Abstract
Abstract The present invention provides a composite elastic material capable of stretching in at least two directions. The material is disclosed as having at least one elastic sheet and at least one necked material joined to the elastic sheet at least at three locations arranged in a nonlinear configuration, so that the necked web is gathered between at least two of those locations. Also disclosed is a method of producing a composite elastic material capable of stretching in at least two directions.
