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.
An absorbent article, comprising: a backsheet layer; a fibrous, liquid permeable topsheet layer for positioning against a wearer\s skin, said topsheet layer having length and width dimensions and disposed in facing relation with said backsheet layer; an absorbent retention portion which is interpose
An absorbent article, comprising: a backsheet layer; a fibrous, liquid permeable topsheet layer for positioning against a wearer\s skin, said topsheet layer having length and width dimensions and disposed in facing relation with said backsheet layer; an absorbent retention portion which is interposed between said backsheet layer and topsheet layer, said retention portion having length and width dimensions smaller than corresponding dimensions of said topsheet layer and comprising a matrix of substantially hydrophilic fibers having a distribution of high-absorbency particle material therein, said hydrophilic fibers and high-absorbency particles provided in a fiber-to-particle ratio which is not more than about 70:30 and is not less than about 30:70 by weight; a fibrous surge management layer which is arranged to transport liquid therethrough and includes bicomponent fibers having a denier of not more than about 3 d, said surge management layer having a facing surface thereof located in an adjacent, facing relation with at least one major, facing surface of said topsheet layer and thereby arranged to transport liquid between said facing surface of said surge management layer and said adjacent facing surface of said topsheet layer; a multi-element wrapsheet which is located between said backsheet layer and said surge management layer and is placed adjacent major surfaces of said retention portion; said multi-element wrapsheet including a bodyside wrap layer and a separate outerside wrap layer, each of which extends past all or some peripheral edges of said fiber matrix to provide an outwardly protruding flange-type bonding region over which an entire or partial periphery of the bodyside wrap layer is connected to an entire or partial periphery of the outerside wrap layer.
