Abstract
An absorbent article including a fluid pervious topsheet, a fluid impervious backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and the backsheet. The topsheet includes a fluid pervious nonwoven material having a patterned network of fluid impervious areas deposited thereon. Bodily fluid deposited on the topsheet is transported through the fluid pervious nonwoven material portion of the topsheet, thereby wetting the nonwoven material while the fluid impervious areas remain dry. The dry fluid impervious areas contrast visually with the wetted nonwoven material portion of the topsheet. This structure provides a topsheet that is perceived as soft and fibrous prior to the discharge of bodily fluids thereon and clean and dry after bodily fluids have been deposited thereon.
