Abstract:
1. An absorbent article comprising a liquid pervious topsheet comprising a first portion and a second portion, wherein said first portion differs in structure from said second portion, said topsheet having an area; wherein said topsheet has a longitudinal centerline and a transverse centerline; wherein said second portion comprises a first structurally modified zone, a second structurally modified zone, a third structurally modified zone, and a fourth structurally modified zone; wherein said first structurally modified zone and said second structurally modified zone are on opposing sides of said longitudinal centerline and said first structurally modified zone and said second structurally modified zone are on opposing sides of an axis parallel to said transverse centerline; wherein said third structurally modified zone is disposed on the same side of said longitudinal centerline as said first structurally modified zone, wherein said first structurally modified zone and said third structurally modified zone are disposed on opposing sides of an axis parallel to said transverse centerline; wherein said fourth structurally modified zone is disposed on the same side of said longitudinal centerline as said second structurally modified zone, wherein said second structurally modified zone and said fourth structurally modified zone are disposed on opposing sides of an axis parallel to said transverse centerline; wherein said first structurally modified zone, said second structurally modified zone, said third structurally modified zone, and said fourth structurally modified zone are spaced apart from one another; wherein said first structurally modified zone, said second structurally modified zone, said third structurally modified zone, and said fourth structurally modified zone together comprise more than about 10% of the area of said topsheet; wherein said first structurally modified zone is different from said third structurally modified zone through a difference in size or pattern of structures defining the respective first and third structurally modified zones, and wherein said second structurally modified zone is different from said fourth structurally modified zone through a difference in size or pattern of structures defining the respective second and fourth structurally modified zones.
