Abstract
An absorbent article is provided. The absorbent article includes a nonwoven, liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed at least partially intermediate the topsheet and the backsheet. The topsheet includes a layer of fibers and has a plurality of apertures defined in the layer of fibers. At least some of the apertures have a side wall having a portion disposed an angle in the range of about 55 degrees to about 90 degrees, in the range of about 60 degrees to about 80 degrees, or in the range of about 63 degrees to about 75 degrees, according to the 2D X-Ray CT Scan Test herein.
