Abstract

A laminate web comprising a first and second precursor webs, at least the first precursor web being a nonwoven web, the laminate web having a first side, the first side comprising the second precursor web and at least one discrete tuft, each of the discrete tufts having a linear orientation defining a longitudinal axis and comprising a plurality of tufted fibers being integral extensions of the first precursor web and extending through the second precursor web; and a second side, the second side comprising the first precursor web.

Claims (12)

1. A laminate web comprising first and second precursor webs, said laminate web having a machine direction and a cross machine direction defining a MD-CD plane, at least the first precursor web being a nonwoven web, the laminate web having a first side, the first side comprising the second precursor web and at least one discrete tuft, each of the discrete tufts having a linear orientation defining a longitudinal axis in said MD-CD plane and comprising a plurality of tufted fibers being integral extensions of the first precursor web and extending through the second precursor web; and a second side, the second side comprising the first precursor web; wherein said plurality of tufted fibers being integral extensions of the first precursor web comprises both a first plurality of looped fibers and a second plurality of non-looped fibers, and wherein said first plurality of looped fibers define a tunnel-like shaped tuft having opposing longitudinal open ends.

2. The laminate web of claim 1 , wherein said web comprises a plurality of discrete tufts.

3. The laminate web of claim 1 , wherein said first precursor web comprises a nonwoven web of substantially randomly oriented fibers.

4. The laminate web of claim 1 , wherein a portion of each said tuft defines an open void area internal to said tufts.

5. A wipe comprising said laminate web of claim 1 .

6. A disposable absorbent article, said article having at least one component comprising a laminate web, said laminate web having a machine direction and a cross machine direction defining a MD-CD plane, said laminate web comprising first and second precursor webs, at least the first precursor web being a nonwoven web, the laminate web having a first side, the first side comprising the second precursor web and at least one discrete tuft, each of the discrete tufts having a linear orientation defining a longitudinal axis in said MD-CD plane and comprising a plurality of tufted fibers being integral extensions of the first precursor web and extending through the second precursor web; and a second side, the second side comprising the first precursor web; wherein said plurality of tufted fibers being integral extensions of the first precursor web comprises both a first plurality of looped fibers and a second plurality of non-looped fibers, and wherein said first plurality of looped fibers define a tunnel-like shaped tuft having opposing longitudinal open ends.

7. The article of claim 6 , wherein said article is selected from the group consisting of a catamenial device, a tampon, or a diaper.

8. The article of claim 6 wherein said laminate web comprises a topsheet of said disposable absorbent article.

9. The article of claim 6 wherein said laminate web comprises a core of said disposable absorbent article.

10. The laminate web of claim 1 , wherein at least one of said first precursor web and said second precursor web comprises nanofibers having a mean diameter of less than 1 micron.

11. The article of claim 6 , wherein at least one of said first precursor web and said second precursor web comprises nanofibers having a mean diameter of less than 1 micron.

12. A laminate web comprising first and second precursor webs, said laminate web having a machine direction and a cross machine direction defining a MD-CD plane, at least the first precursor web being a nonwoven web, the laminate web having a first side, the first side comprising the second precursor web and at least one discrete tuft, each of the discrete tufts having a linear orientation defining a longitudinal axis in said MD-CD plane and comprising a plurality of tufted fibers being integral extensions of the first precursor web and extending through the second precursor web; and a second side, the second side comprising the first precursor web; wherein said plurality of tufted fibers comprises looped fibers that collectively define a tunnel-like shaped tuft having opposing longitudinal open ends.
