Abstract
The present invention provides an absorbent article having a first waist region, an opposed second waist region, a crotch region disposed between the first waist region and the second waist region. The absorbent article preferably comprises a liquid impervious backsheet material, an absorbent core and a directionally preferential waste passage member. The waste passage member has a body facing surface and an opposed garment facing surface, at least a portion of the body facing surface of the waste passage member including a soluble material capable of dissolving when contacted by bodily exudates so as to permit the bodily exudates to pass through the waste passage member in a direction generally away from the wearer's skin. At least a portion of the garment facing surface of the waste passage member includes a barrier material which resists penetration by the bodily exudates in a direction opposite from the first direction. The waste activated barrier member is preferably disposed in at least a portion of the crotch region of the absorbent article.
