Abstract

Disclosed is a fibrous web having a first region and at least one discrete integral second region, the second region having at least one portion being a discontinuity exhibiting a linear orientation and defining a longitudinal axis, and at least another portion being a deformation having a plurality of tufted fibers integral with but extending from the first region.

First claim

What is claimed is:

1. A multilayer web comprising:
a. a first nonwoven;
b. a second nonwoven that is different from the first nonwoven; and
c. a plurality of fiber tufts extending from a surface of one of the first nonwoven and the second nonwoven, the plurality of fibers tufts comprising fibers from both the first nonwoven and the second nonwoven;
d. wherein the difference between the first nonwoven and the second nonwoven is their fiber composition; and
e. wherein at least some of the plurality of fiber tufts comprise fibers that are integral with and extend from one of the first nonwoven and the second nonwoven, and that extend completely through the other of the first nonwoven and the second nonwoven.

2. The multilayer web of claim 1 , wherein the first nonwoven comprises relatively hydrophobic fibers and the second nonwoven comprises relatively hydrophilic fibers.

3. The multilayer web of claim 1 , wherein the first nonwoven comprises substantially continuous fibers and the second nonwoven comprises staple fibers.

4. The multilayer web of claim 1 , wherein the first nonwoven comprises polyethylene fibers and the second nonwoven comprises polyester fibers.

5. The multilayer web of claim 1 , wherein at least one of the first nonwoven and the second nonwoven comprises cellulose, rayon, and/or cotton fibers.

6. The multilayer web of claim 1 , wherein at least one of the first nonwoven and the second nonwoven comprises splittable fibers.

7. The multilayer web of claim 1 , wherein at least one of the first nonwoven and the second nonwoven comprises nanofibers.

8. The multilayer web of claim 1 , wherein at least one of the first nonwoven and the second nonwoven comprises non-round fibers.

9. The multilayer web of claim 1 , wherein the first nonwoven comprises bicomponent fibers and the second nonwoven comprises monocomponent fibers.

10. A personal hygiene product comprising the multilayer web of claim 1 , wherein the personal hygiene product has a body facing side and wherein the plurality of fiber tufts extend in a direction opposite to the body facing side.

11. The personal hygiene product of claim 10 , wherein the multilayer web at least partially forms a topsheet or secondary topsheet of the personal hygiene product.

12. A personal hygiene product comprising the multilayer web of claim 1 , wherein the first nonwoven forms a body facing side of the personal hygiene product.

13. A personal hygiene product comprising the multilayer web of claim 1 , wherein the second nonwoven forms a body facing side of the personal hygiene product.

14. A multilayer web comprising:
a. a first nonwoven;
b. a second nonwoven that is different from the first nonwoven; and
c. a plurality of fiber tufts extending from a surface of one of the first nonwoven and the second nonwoven, the plurality of fibers tufts comprising fibers from both the first nonwoven and the second nonwoven;
d. wherein the difference between the first nonwoven and the second nonwoven is their construction; and
e. wherein at least some of the plurality of fiber tufts comprise fibers that are integral with and extend from one of the first nonwoven and the second nonwoven, and that extend completely through the other of the first nonwoven and the second nonwoven.

15. The multilayer web of claim 14 , wherein the first nonwoven is a spunbond nonwoven and the second nonwoven is a thermal bonded, carded nonwoven.

16. The multilayer web of claim 14 , wherein the spunbond nonwoven comprises side-by-side configured bicomponent fibers.

17. The multilayer web of claim 14 , wherein the first nonwoven is a hydroentangled nonwoven.

18. The multilayer web of claim 14 , wherein the plurality of fiber tufts comprises looped fibers.

19. A personal hygiene product comprising the multilayer web of claim 14 , wherein the personal hygiene product has a body facing side and wherein the plurality of fiber tufts extend in a direction opposite to the body facing side.

20. The personal hygiene product of claim 19 , wherein the multilayer web at least partially forms a topsheet or secondary topsheet of the personal hygiene product.

21. A personal hygiene product comprising the multilayer web of claim 14 , wherein the first nonwoven forms a body facing side of the personal hygiene product.

22. A personal hygiene product comprising the multilayer web of claim 14 , wherein the second nonwoven forms a body facing side of the personal hygiene product.
