ABSTRACT:
Disclosed is an absorbent article having an absorbent core. The absorbent core includes a primary absorbent member and a secondary absorbent member. The primary absorbent member has a fluid distribution rate, expressed as the ratio of a stain area in the primary absorbent member to a stain area in the secondary absorbent member, along a X-Y direction greater than about 1.8 times faster than the secondary absorbent member. The fluid distribution rate is expressed as a ratio of a stain area in the primary absorbent member to a stain area in the secondary absorbent member five minutes after a given volume of test fluid insults the absorbent core. The secondary absorbent member has a substantial portion thereof composed of a non-absorbent polymeric composition. The secondary absorbent member is superposed over a portion of the primary absorbent member. In a preferred embodiment, the secondary absorbent member has an aperture or orifice having an open surface area greater than about 20% of the secondary absorbent member surface area.
