The present invention provides a method for selectively aperturing a nonwoven web. A nonwoven web is weakened along a plurality of locations and then a tensioning force is applied to the nonwoven web causing the nonwoven web to rupture at the plurality of weakened location creating a plurality of apertures in the nonwoven web coincident with the weakened locations

[ What is claimed is:] [1.] A nonwoven web made according to the method comprising the steps of:a) providing a nonwoven web, wherein said nonwoven web is provided with a patterned plurality of spaced apart discrete bonds to form a coherent web structure;b) weakening said nonwoven web at a plurality of locations to create a plurality of weakened, melt-stabilized locations, wherein a portion of said spaced apart descrete bonds are seperated from said melt-stabilized locations; andc) applying a tensioning force to said nonwoven web to cause said nonwoven web to rupture at said plurality of weakened, melt-stabilized locations so as to create a plurality of apertures in said nonwoven web coincident with said plurality of weakened, melt-stabilized locations, said apertures having a circumferential edge, a portion of which edge is defined by a remnant of the melt stabilized locations, without substantially rupturing any of said spaced apart discrete seperated bonds that are from said melt stabilized locations.
