ABSTRACT:
A disposable, absorbent diaper comprising a topsheet, a liquid impervious backsheet associated with the topsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent core has a dusting layer of mechanical pulp fibers, a continuous primary layer of mechanical pulp fibers containing from about 8% to about 60%, on a total primary layer dry weight basis, of discrete particles of polymeric gelling material, and a water-permeable core reinforcing layer disposed between the dusting layer and the primary layer. The mechanical pulp fibers, preferably chemithermomechanical pulp fibers, have an average fiber length of at least about 1.9 mm and are in a highly disintegrated condition.
