Abstract
An apertured nonwoven web is provided. The apertured nonwoven web comprises carded fibers, a first side, and a second side. The apertured nonwoven web defines a plurality of apertures therein. The apertures may each have a first side aperture size and a second side aperture size, and a ratio of the first side aperture size to the second side aperture size may be between about 1.15:1 to about 1:1.15. The plurality of apertures may have an aperture size regularity of about 1% to about 15%. The plurality of apertures may have an aperture shape regularity between about 1% to about 12%.
