Abstract
Absorptive devices, such as disposable diapers, presenting a dry surface feel to the user. In a particularly preferred embodiment of the present invention, a substantially planar, moisture absorbent layer is disposed between a soft and bulky, wearer contacting, moisture-pervious topsheet and a moisture-resistant backing sheet to form a disposable diaper. The topsheet preferably comprises an integral structure containing a multiplicity of depressed areas which intimately contact the uppermost surface of a substantially planar, moisture absorbent layer, while the non-depressed areas of the topsheet contact the wearer's skin in-use. Due to the wet resilience and increased overall caliper of the topsheet, the non-depressed areas, which are of substantially the same density as the depressed areas, tend to isolate the wearer's skin from moisture contained within the moisture absorbent layer, thereby providing improved surface dryness and improved resistance to rewetting when the structure is temporarily subjected to pressure resulting from the wearer's body movements.
