Abstract

An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet is disclosed. The topsheet has a first side and a second side, the first side being a body-facing side and the second side being in fluid communication with the absorbent core. The topsheet also has a first relatively hydrophobic component and a second relatively hydrophilic component, the relatively hydrophilic component extending through the relatively hydrophobic component and being disposed on both of the sides of the topsheet. The absorbent article exhibits a rewet value of less than about 94 mg, and a fluid acquisition rate of at least about 0.10 ml/sec when tested by the Gush Acquisition and Rewet Test Method.

Claims (10)

1. An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, the topsheet having a first side and a second side, the first side being a body-facing side and the second side being in fluid communication with the absorbent core, said topsheet further characterized by:
a. a first relatively hydrophobic component and a second relatively hydrophilic component;
b. said relatively hydrophilic component extending through said relatively hydrophobic component and being disposed on both of said sides of said topsheet; and c. wherein said absorbent article exhibits a rewet value of less than about 94 mg, and a fluid acquisition rate of at least about 0.10 ml/sec when tested by the Gush Acquisition and Rewet Test Method.
2. The absorbent article of Claim 1, further characterized in that the topsheet is a laminate of a relatively hydrophobic web and a relatively hydrophilic nonwoven web.
3. The absorbent article of Claim 1 or 2, further characterized in that the first side of the topsheet comprises a plurality of discrete tufts comprising fibers from said relatively hydrophilic nonwoven web.
4. The absorbent article of any of the preceding claims, wherein said fibers of either said relatively hydrophilic web or said relatively hydrophobic web comprise non-round fibers.
5. The absorbent article of Claim 1, further characterized in that said absorbent article exhibits a rewet value of less than about 50 mg, more preferably less than about 25 mg, and a fluid acquisition rate of at least about 0.50 ml/sec when tested by the Gush Acquisition and Rewet Test Method.
6. An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, the topsheet having a first side and a second side, the first side being a body-facing side and the second side being in fluid communication with the absorbent core, said topsheet characterized by a nonwoven web and tufted regions, said tufted regions comprising first, second and third zones, each said zone being characterized by the zone fiber orientation, wherein said first and third zones comprise fibers having portions orientated substantially parallel to a plane of the topsheet, and said second zone is intermediate and adjacent to said first and third zones, said second zone comprising fibers having substantially no portions oriented substantially parallel to said plane of the topsheet.
7. An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, the topsheet having a first side and a second side, the first side being a body-facing side and the second side being in fluid communication with the absorbent core, said topsheet characterized by a nonwoven web comprising tufts, said tufts at least partially originating in said second side and extending to a distal body-facing portion, the distal body-facing portion being relatively hydrophobic with respect to the second side.
8. The absorbent article of Claim 7 wherein said distal body-facing portion of said tufts is rendered hydrophobic by a lotion composition disposed thereon.
9. The absorbent article of Claim 7 or 8 wherein said lotion composition comprises a hydrophilic/lipophilic balance (HLB) of less than or equal to 7.
10. The absorbent article of Claim 9 wherein said lotion composition comprises petrolatum.
