  • Publication number: 20030199845
    Abstract: A wearable disposable absorbent article useful for facilitating toilet training. The wearable disposable absorbent article includes a wetness sensation member having a permeable body-facing layer and an impermeable layer disposed between the permeable layer and an absorbent core in a face-to-face arrangement with the permeable layer. During insults of urine, the permeable layer allows urine to penetrate in the z-direction and provides a medium for the flow of urine in the x-y plane via wicking. The impermeable layer prevents the urine from passing completely through the wetness sensation member in the z direction and supports the movement of the urine in an x-y plane to enhance the wearer's awareness that urination has occurred by increasing the wetted area contacting the wearer's skin. The wetness sensation member preferably is held in close contact with a wearer's skin during use.
