Abstract

Deformed web materials are disclosed. The web materials have discrete deformations formed therein. The deformations may be features in the form of portions of a web with apertures therein, protrusions, depressed areas, and combinations thereof. These features may extend out from the surface on one side of the web, or from both of the surfaces of the web. Different features may be intermixed with one another.

First claim

What is claimed is:

1. A web material comprising a nonwoven, said web material having discrete features formed therein, said web material having a first side and a second side, said web material comprising:
a) substantially undeformed regions, said substantially undeformed regions having surfaces that correspond to the first and second surfaces of said web material;
b) a plurality of spaced apart discrete first macroscopic features, at least some which comprise three dimensional portions of said web material having a distal end with an aperture therein; and
c) a plurality of spaced apart discrete second macroscopic features, each of the plurality of spaced apart discrete second macroscopic features comprising an aperture, and wherein the apertures of the second macroscopic features are two dimensional;
wherein at least some of said second features are intermixed with said first features, wherein said three dimensional portions forming first features extend out of a plane of the web on the first side and wherein the first features have a first population per square inch and the second features have a second population per square inch, and wherein the first population and the second population are different.

2. The web of claim 1 , wherein the first macroscopic features are aligned in rows in a machine direction for the web.

3. The web of claim 2 , wherein the second macroscopic features are aligned in rows in a machine direction for the web.

4. The web of either claim 1 or 3 , wherein the first macroscopic features are offset from the second macroscopic features in the machine direction.

5. The web of claim 1 , wherein the first macroscopic features are aligned in rows in a cross direction for the web.

6. The web of claim 2 , wherein the second macroscopic features are aligned in rows in a cross direction for the web.

7. The web of either claim 1 or 3 , wherein the first macroscopic features are offset from the second macroscopic features in the cross direction.

8. A disposable absorbent article comprising the nonwoven of claim 1 , a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core disposed between the topsheet and the backsheet.

9. The disposable absorbent article of claim 8 , wherein the nonwoven forms at least part of the liquid pervious topsheet.

10. The disposable absorbent article of claim 8 , wherein the nonwoven forms at least part of the liquid impervious backsheet.

11. The disposable absorbent article of claim 9 , which is a sanitary napkin or panty liner.

12. The disposable absorbent article of claim 9 , which is an adult incontinence article.

13. The disposable absorbent article of claim 9 , which is a diaper.
