Abstract
The present invention provides a composite elastic material adapted to stretch in at least two directions and which includes at least one reversibly necked material. The composite elastic material is disclosed as having at least one elastic sheet and at least one reversibly necked material joined to the elastic sheet at least at three locations arranged in a nonlinear configuration, so that the reversibly necked material is gathered between those locations. Also disclosed is a method of producing such a composite elastic material.
Claims26
A composite elastic material capable of stretching in at least two directions comprising:
- at least one elastic sheet;
- and
- at least one reversibly necked material joined to the elastic sheet at least at least at three locations arranged in a nonlinear configuration, the reversibly necked material being gathered between at least two of the locations.
A composite elastic material capable of stretching in at least two directions comprising:
- at least one elastic web of meltblown fibers;
- and
- at least one reversibly necked nonwoven web of polypropylene fibers joined to the elastic web at least at three locations arranged in a nonlinear configuration, the reversibly necked nonwoven web being gathered between at least two of the locations.
