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.

Claims (13)

1. A fibrous web comprising a first region and at least one discrete integral second region, said fibrous web having a machine direction and a cross machine direction defining an MD-CD plane, the second region having at least one portion being a discontinuity exhibiting a linear orientation and defining a longitudinal axis (L) in the MD-CD plane and at least another portion being a deformation comprising a plurality of tufted fibers integral with but extending from the first region, wherein each of the plurality of tufted fibers comprises a plurality of looped fibers to define a tunnel-like shaped tuft having opposing longitudinal open ends, and wherein said tufted fibers have an average tufted fiber diameter and said first region has a first region average fiber diameter, wherein said average tufted fiber diameter is less than said first region average fiber diameter.

2. The fibrous web of claim 1 , wherein said web comprises a plurality of discrete integral second regions.

3. The fibrous web of claim 2 , wherein said plurality of discrete integral second regions is uniformly distributed on said fibrous web.

4. The fibrous web of claim 1 , wherein said fibrous web comprises a nonwoven web of substantially randomly oriented fibers.

5. The fibrous web of claim 2 , wherein said fibers comprise materials selected from the group consisting of cellulose, rayon, cotton, polyethylene, polypropylene, polyester, and blends thereof.

6. The fibrous web of claim 2 , wherein said fibers comprise bicomponent fibers.

7. The fibrous web of claim 2 , wherein said fibers comprise non-round fibers.

8. The fibrous web of claim 1 , wherein said web comprises at least 10discrete integral second regions per square centimeter.

9. The fibrous web of claim 1 , wherein a portion of said tufted fibers define an open void area internal to said second regions.

10. A wipe comprising said fibrous web of claim 1 .

11. The fibrous web of claim 1 , wherein an absorbent core is disposed between said first region and a backsheet.

12. The fibrous web of claim 1 , wherein said plurality of tufted fibers comprises nanofibers.

13. The fibrous web of claim 1 , further comprising a lotion.
