Abstract
An absorbent article is provided with inversely related basis weight and density gradients for absorbing and retaining body liquids. A central target area of the absorbent article has an average higher basis weight and a lower average density than end areas. Superabsorbent material is selectively disposed within the article.
Claims3
An absorbent article, comprising:
- a layer comprising generally oppositely disposed end areas, a target area between said end areas, and a top surface and a bottom surface defining therebetween a layer thickness,
- said target area having a higher average basis weight and a lower average density than one of said end areas,
- said layer further comprising an absorbent fibrous material and superabsorbent particles, all of said superabsorbent particles being in a discrete lamina.
An absorbent article, comprising:
- a layer comprising generally oppositely disposed end areas and generally oppositely disposed side areas, a target area between said end areas, and a top surface and a bottom surface defining therebetween a layer thickness,
- said target area having a higher average basis weight and a lower average density than one of said end areas,
- said target area having a higher average basis weight and a higher average density than said side areas,
- said one end area having a higher average density than said side areas,
- said layer further comprising an absorbent fibrous material and superabsorbent particles, at least a portion of said superabsorbent particles being in a discrete lamina.
