Title of Invention

AN ABSORBENT ARTICLE WITH IMPROVED TOPSHEET

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...

We claim:
1. An absorbent article (200) comprising a topsheet (206), a backsheet (202), and
an absorbent core (204) disposed between the topsheet (206) and the backsheet (202), the
topsheet (206) 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 (204), said
topsheet (206) further characterized by:
a. a first relatively hydrophobic component (21) and a second relatively
hydrophilic component (20);
b. said relatively hydrophilic component (20) extending through said relatively
hydrophobic component (21) and being disposed on both of said sides of said
topsheet (206); and
c. wherein said absorbent article (200) 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 (200) of Claim 1, wherein said topsheet (206) is a laminate of a relatively hydrophobic web (21) and a relatively hydrophilic non woven web (20).
3. The absorbent article (200) of Claim 1 or 2, wherein said first side of the topsheet (206) comprises a plurality of discrete tufts (6) comprising fibers from said relatively hydrophilic nonwoven web (20).
4. The absorbent article (200) of any of the preceding claims, wherein said fibers of either said relatively hydrophilic web (20) or said relatively hydrophobic web (21) comprise non-round fibers.
5. The absorbent article (200) of Claim 1, wherein said absorbent article (200) 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 (200) as claimed in claim 3, wherein said tufts (6) are comprised in tufted regions, said tufted regions comprising first (Zl), second (Z2) and third zones (Z3), each said zone being comprising the zone fiber orientation, wherein said first (Zl) and third (Z3) zones comprise fibers having portions orientated substantially parallel to a plane of the topsheet (206), and said second zone (Z2) is intermediate and adjacent to said first (Zl) and third (Z3) zones, said second zone (Z2) comprising fibers having substantially no portions oriented substantially parallel to said plane of the topsheet (206).
7. An absorbent article (200) as claimed in claim 3, wherein said tufts are at least partially originating in said second side and extending to a distal body-facing portion (31), the distal body-facing portion (31) being relatively hydrophobic with respect to the second side.
8. The absorbent article (200) of Claim 7 wherein said distal body-facing portion (31) of said tufts (6) is rendered hydrophobic by a lotion composition disposed thereon.

9. The absorbent article (200) of Claim 7 or 8 wherein said lotion composition comprises a hydrophilic/iipophilic balance (HLB) of less than or equal to 7.
10. The absorbent article (200) of Claim 9 wherein said lotion composition comprises petrolatum.
