Abstract:
1. A method of forming a nonwoven composite, the method comprising: forming an elastic film from an elastomeric polymer; passing the film and a nonwoven web material that contains fibers through a nip formed by at least one roll patterned with raised bonding elements; and at the nip, concurrently forming apertures in the film and melt fusing the film to the nonwoven web material so that the elastomeric polymer physically adheres to the fibers at a plurality of corresponding discrete bond sites, thus forming one or more discrete bond sites between the film and the nonwoven web material located proximate to a perimeter defined by at least one of the apertures, wherein at least one aperture has a length of from about 200 to about 5000 micrometers, and wherein the nonwoven web material remains generally unapertured at an area adjacent to the aperture in the film and remains generally unbonded to the film except at the corresponding discrete bond sites after being melt fused to the film.
