Abstract

A personal care absorbent article, such as a sanitary pad or napkin, wound dressing, and the like having an absorbent material treated with a fluid treatment agent, which fluid treatment agent causes red blood cells in a blood-containing fluid to agglomerate or lyse as the fluid passes into and/or through the absorbent article. In accordance with one preferred embodiment, the absorbent material is a porous nonwoven web material, comprising a porisity gradient with pore size increasing from one side of web material to the opposite side.

Claims 1, 16, 40 and 53 have been amended to identify the fluid treatment agent as comprising a material selected from the group consisting of a tri-biock copolymer comprising polypropylene oxide and polyethylene oxide, a polycationic surfactant linear polymer, polylysine, an antibody, a saponin, an octylpolyglycoside and combinations thereof. The dependencies of Claims 12 and 23 have been amended to depend from Claims 1 and 16, respectively due to the deletion of the claims from which they originally depended. Claim 24 has been amended to identify the porous synthetic substrate as comprising a nonwoven material selected from the group consisting of spunbond, meltblown, airlaid and
bonded carded.
Applicant respectfully urges that this amendment of the claims is fully supported by the application as originally filed and, thus, incorporates no new subject matter into the application.
