Abstract
An apertured nonwovens having a first nonwoven layer is described. The first nonwoven layer includes cellulose-based fibers and a plurality of apertures, wherein the plurality apertures have a minimum aperture distance between two adjacent apertures which has a relative standard deviation no greater than about 40%, as measured according to the Aperture Quality Test. The apertures have an aperture size no greater than about 2.2 mm2 and have an occlusion no greater than about 9%, as measured according to the Aperture Quality Test, or the apertures have an aspect ratio no greater than about 2.5 as measured according to the Aspect Ratio Test.
