Abstract:
An absorbent product, having opposing longitudinal edges and opposing transverse edges, and comprising a body facing liquid permeable sheet, an undergarment facing air permeable, substantially liquid impermeable barrier structure, and an absorbent structure therebetween, the barrier structure comprising at least one porous layer having opposing sides, the porous layer being comprised of:a porous substrate having pores, which extend between opposing sides that correspond to the opposing sides of the porous layer, whereby a liquid may transverse the substrate; andparticles that are fused to the at least one side of the porous substrate so as to restrict entry of the liquid into the pores;wherein the porous layer substantially resists penetration by the liquid when it is contained in a test absorbent product that overlays the first side of the porous layer to which the particles are fused, and is under a loading of one pound per square inch; and wherein the barrier structure has a Frazier air permeability value of greater than zero mm.sup.3 /m.sup.2 /min.
