The present invention is directed to a matched permeability liner/absorbent structure system, suitable for use in absorbent articles, in which the permeability of the bodyside liner is correlated with the permeability of the subjacent layer of the absorbent structure, such as a surge layer. The inventors have observed that by appropriately matching the permeability of the liner material to the permeability of the subjacent layer, liquid intake performance of the liner and subjacent layer materials can exceed liquid intake performance of the subjacent layer material alone. Thus, in accordance with an embodiment of the present invention, the permeability of the bodyside liner is set within a specified range of that of the subjacent layer such that the liner/subjacent layer liquid intake performance is improved. In accordance with another embodiment of the present invention, the permeability of the bodyside liner is matched to or correlated with the permeability of the subjacent layer such that the liner/subjacent layer liquid intake performance is improved at least about 50 percent over the liquid intake performance of the subjacent layer alone. In accordance with yet another embodiment of the present invention, the permeability of the liner material is matched to or correlated with the permeability of the subjacent layer such that liquid intake performance of the liner/subjacent layer combination is improved at least about 65 percent over the liquid intake performance of the subjacent layer alone. As disclosed herein, by properly selecting the permeability of the liner material, as compared with the permeability of the subjacent layer material, the liquid intake rate of the liner material not only does not limit or inhibit liquid intake into the subjacent layer and underlying components of the absorbent structure, but provides an unexpected increase in liquid intake performance over that of the subjacent layer alone. The bodyside liner and subjacent layer can suitably be formed of fibrous nonwoven webs.

Matched permeability liner/absorbent structure system for absorbent

A distinctive absorbent article comprises a substantially liquid-impermeable outer cover member having a length and a width. The outer cover provides a rear waistband portion and a front waistband portion, and has a layer of polymer film material on an outer surface of the front waistband portion of the outer cover. A liquid permeable topsheet layer is provided for contacting a wearer's skin, and an absorbent body is interposed between the outer cover and the topsheet layer. The absorbent body has a length and width which are smaller than the outer cover length and width, thereby providing end margins and side margins of the outer cover. An adhesive fastening mechanism adheres to the film layer to secure the front and rear waistband portions of the outer cover about the wearer. An elastic member is connected to provide elasticized gathers along a cross-direction of the rear waistband portion of the outer cover. An outermost layer of substantially nonwettable, resilient material is connected to overlie the polymer film of the outer cover along the front waistband portion of the outer cover, thereby sandwiching the polymer film between the topsheet layer and the outermost layer of resilient material. The outermost resilient material has a lengthwise extent which is less than the length of the outer cover.

Disclosed herein a personal care absorbent product which when first insulted, has a high initial surface moisture value which is maintained for several minutes but then, after a short period of time, drops to a lower value. As a result, the product has an initial 'wet' feel but quickly changes to a drier feel so as to provide more comfort.
