An absorbent article, comprising:
- a liquid permeable top sheet,
- a pulpless absorbent core, the core including synthetic fibers and a super absorbent material, the super absorbent material having a PDAUP between about 14 g/g and about 22 g/g;
- and
- a liquid impermeable backsheet;
- wherein the absorbent core is positioned between the top sheet & the backsheet and
- wherein PDAUP is a measurement of the capacity of a swollen super absorbent material to absorb a saline solution under an enclosing pressure and the permeability of the swollen super absorbent material, and is measured as the amount of a 0.9 weight percent NaCl solution absorbed by an amount of super absorbent material during one hour, under a load of approximately 0.7 pounds per square inch.
