Abstract:
A wearable disposable absorbent article for wearing about a lower torso of a wearer and having a longitudinal axis, two laterally opposed article side edges extending between a laterally extending first waist end edge in a first waist region and a laterally extending second waist end edge in a second waist region, and a crotch region interposed therebetween, the wearable disposable absorbent article comprising:a backsheet; a topsheet joined to the backsheet and having a body-facing surface; an absorbent core disposed intermediate the backsheet and the topsheet; and a wetness sensation member held in close contact with the wearer's skin during use and integrated with the topsheet such that a portion of the topsheet covering a portion of the absorbent core forms a permeable body-facing layer of the wetness sensation member, the wetness sensation member also including an impermeable layer disposed between the permeable body-facing layer and the absorbent core in a face-to-face arrangement with the permeable body-facing layer and having two laterally opposed impermeable layer side edges, at least a portion of each of the two impermeable layer side edges being disposed laterally inwardly of the article side edges; wherein urine deposited by the wearer onto the wetness sensation member can penetrate through the permeable body-facing layer in a z direction away from the wearer to the impermeable layer and the impermeable layer prevents urine from passing completely through the wetness sensation member in the z direction and supports the movement of urine in an x-y plane such that the wearer's awareness of urination is enhanced.
