Abstract: The invention provides a diaper with a mechanical fastening system comprising an outer cover, at least one single piece of flexible material with an active fastening surface, a first waist region, a second waist region opposite the first waist region wherein the active fastening surface of the at least one single piece of flexible material provides an at least one fastener and the outer cover defines an inside surface and an outside surface such that in use, the active fastening surface of the at least one fastener anchors to the outside surface of the outer cover in the first waist region and the at least one fastener fastens the outside surface of the outer cover in the second waist region thereby forming a waist opening and a pair of leg openings.

Abstract: Generally stated, the present invention provides a distinctive absorbent article comprising a backsheet layer, and a topsheet layer which is disposed in facing relation with the backsheet layer. An absorbent body is interposed between the backsheet layer and topsheet layer. The absorbent body includes a retention portion which comprises a matrix of substantially hydrophilic fibers having a distribution of high-absorbency particulate material therein. The hydrophilic fibers and high-absorbency particles can be provided in a fiber-to-particle weight ratio within the range of about 70:30 to about 30:70. A surge management layer, comprising bicomponent fibers having a denier of not more than about 3 d, is located adjacent at least one major, facing surface of the topsheet layer, and can cooperate with the article components to provide for a liquid Penetration Rate index of not less than about 2.67 ml/sec.
