Abstract:
A disposable absorbent article having a liner, an outer cover and an absorbent body therebetween for absorbing liquid body waste penetrating the liner. In one embodiment, the absorbent body has an inner layer and an outer layer. The inner layer has a lower absorbent capacity per unit weight than the outer layer. A flow control layer between the inner layer and the outer layer at least retards the flow of liquid body waste from the inner layer to the outer layer to facilitate a prolonged feeling of wetness to the wearer. In another embodiment, a surge layer lies between the liner and an absorbent body. A flow control layer between the liner and the surge layer, or between the surge layer and the absorbent body, at least retards the flow of liquid body waste through the surge layer toward the absorbent body.
