Patterned apertured webs and methods for making the same

Abstract

A disposable absorbent article having a topsheet, a backsheet, and an absorbent core disposed therebetween is described. The topsheet includes a plurality of apertures arranged in a first zone and a first plurality of structures which are disposed adjacent to the first plurality of apertures. The plurality of apertures have an Effective Aperture Area of from between 0.5 mm 2 to about 8 mm 2 as measured by the Aperture/Feret Angle test as described herein, and the topsheet has a top layer and a lower layer, wherein the top layer is more hydrophobic than the lower layer.

What is claimed is: 
     
         1 . A disposable absorbent article comprising a longitudinal axis and a lateral axis generally perpendicular to the longitudinal axis, a pair of side edges extending generally parallel to the longitudinal axis and a pair of end edges joining said pair of side edges on opposite ends of the disposable absorbent article, the disposable absorbent article further comprising:
 a topsheet comprising a web having a length generally parallel to the longitudinal axis and a width generally parallel to the lateral axis, a plurality of apertures arranged in a first zone, a first plurality of structures which are disposed adjacent to the first plurality of apertures, wherein the plurality of apertures have an Effective Aperture Area of from between 0.5 mm 2  to about 8 mm 2  as measured by the Aperture/Feret Angle test as described herein, and wherein the topsheet comprises a top layer and a lower layer, wherein the top layer is more hydrophobic than the lower layer;   a backsheet; and   an absorbent core disposed between the topsheet and the backsheet.   
     
     
         2 . The disposable absorbent article of  claim 1 , wherein the top layer has a basis weight of between 10 gsm and 30 gsm. 
     
     
         3 . The disposable absorbent article of  claim 1 , wherein the lower layer has a basis weight of between 10 gsm and 30 gsm.
