Abstract:
1. A method for making a highly extensible apertured nonwoven web comprising the steps of: a) providing a nonwoven web comprising spunbond bicomponent fibers, said nonwoven web having a length measured in a machine direction and a first width measured in a cross machine direction, said nonwoven web having a peak CD extensibility of at least 150%; b) weakening said nonwoven web at a plurality of locations to create a plurality of weakened, melt-stabilized locations; c) applying a first tensioning force to said nonwoven web to cause said nonwoven web to rupture at said plurality of weakened, melt-stabilized locations creating a plurality of apertures in said nonwoven web coincident with said plurality of weakened, melt-stabilized locations, said first tensioning force causing said nonwoven web to have a second width; d) incrementally stretching said nonwoven to locally extend portions of said nonwoven web in a direction substantially parallel to said cross machine direction to a third width that is greater than the second width; and e) applying tension to said nonwoven web in the machine direction such that said nonwoven web has a width less than said third width.
