ABSTRACT:
An absorbent article having two coapertured layers and a method of making the absorbent article are disclosed. The absorbent article includes first and second layers formed from nonwoven materials. The first layer has an open pore structure and has an average fiber denier greater than about 2.5. The second layer has a finer pore structure than the first layer. The first layer overlays the second layer and both layers have a plurality of coaxially aligned apertures formed completely therethrough. The apertures allow body fluid, especially viscous fluid like menses, which is deposited on the first layer to rapidly pass down through both layers.
