Abstract

A distinctive absorbent article includes a backsheet layer which has a width dimension and a length dimension, and which includes a front waistband section, a back waistband section, and an intermediate section interconnecting the front and back waistband sections. An absorbent body is superposed on the backsheet layer, and an intermediate transfer layer, which is liquid permeable, is disposed in facing relation with the absorbent body to generally sandwich the absorbent body between the backsheet and transfer layer. The transfer layer has an appointed bodyside, inner surface, and a bodyside liner layer is located on the inner surface of the transfer layer. The bodyside liner comprises a bonded carded web which has a basis weight within the range of about 15-40 gsm and is composed of bicomponent fibers having a fiber denier within the range of about 1.0-3.0 dpf. The bodyside liner is constructed to provide for a Penetration rate index of at least about 1.5 ml/sec and a Retention index of not more than about 0.8 gm.
