<p>An absorbent structure providing a substantially dry liquid-accepting surface after application of a quantity of liquid to the surface, the structure comprising a first planar region defining an upper, liquid-accepting surface of the absorbent structure comprising an upper layer comprising hydrophilic synthetic fibers, the layer having a first average pore size of about 75 to 400 mu m; and a lower layer disposed below and in fluid communication with the upper layer, comprising an air-laid mixture of natural pulp fibers and hydrophilic synthetic fibers, the layer having a second average pore size, less than the first average pore size, within the range of about 40 to 140 mu m; and a second planar region, disposed below and in fluid communication with the lower layer of the first planar region, comprising an upper layer comprising about 20 to 95 wt-% resilient hydrophilic fibers and about 5 to 80 wt-% superabsorbent material, having a third average pore size of about 400 to 1,000 mu m; and a lower layer disposed below and in fluid communication with the upper layer of the second planar region, comprising an air-laid mixture of natural pulp fibers and hydrophilic synthetic fibers, the layer having a fourth average pore size of about 40 to 140 mu m.</p> |
