Abstract

A patterned apertured web comprises a layer comprising a plurality of apertures and a plurality of land areas. The plurality of apertures comprise a first set of apertures in a first zone and a second set of apertures in a second zone. The first set of apertures in the first zone have Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances of the first set of apertures have a first distribution having a first mean and a first median. The first mean is different than the first median. The second set of apertures in the second zone have Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances of the second set of apertures have a second distribution having a second mean and a second median. The second mean is different than the second median. The first and second sets of apertures have different patterns.

First claim

What is claimed is:

1 . A patterned apertured web comprising:
a plurality of first arrays forming a first zone in the patterned apertured web, wherein at least some of the first arrays comprise:
a first plurality of land areas; and
a first plurality of apertures, wherein at least some of the first plurality of land areas surround at least some of the first plurality of apertures;
wherein the first plurality of apertures of the first zone have a plurality of Interaperture Distances, according to the Aperture Test herein, wherein the Interaperture Distances of the first zone have a first distribution having a first mean and a first median, and wherein the first mean is greater than the first median by at least 4%; and
wherein the first arrays comprise an Effective Open Area in the range of about 5% to about 50%, according to the Aperture Test herein; and
a plurality of second, different arrays forming a second zone in the patterned apertured web, wherein at least some of the second arrays comprise:
a second plurality of land areas; and
a second plurality of apertures, wherein at least some of the second land areas surround at least some of the second plurality of apertures;
wherein the second plurality of apertures of the second zone have a plurality of Interaperture Distances, according to the Aperture Test herein, wherein the Interaperture Distances of the second zone have a second distribution having a second mean and a second median, and wherein the second mean is greater than the second median; and
wherein the second arrays comprise an Effective Open Area of about 5% to about 50%, according to the Aperture Test herein.

2 . The patterned apertured web of claim 1 , comprising two or more layers.

3 . The patterned apertured web of claim 2 , wherein a first layer comprising a nonwoven material, and wherein a second layer comprises a nonwoven material.

4 . The patterned apertured web of claim 2 , wherein the first layer comprises a nonwoven material, and wherein a second layer comprises a film.

5 . The patterned apertured web of claim 2 , wherein a first layer has a different color or opacity than a second layer.

6 . The patterned apertured web of claim 1 , wherein the first plurality of apertures in the first array or the second plurality of apertures in the second array form a substantially continuous pattern.

7 . The patterned apertured web of claim 1 , wherein the first plurality of apertures in the first array or the second plurality of apertures in the second array form a discrete pattern.

8 . The patterned apertured web of claim 1 , wherein the first plurality of land areas in the first array or the second plurality of apertures in the second array form a substantially continuous pattern.

9 . The patterned apertured web of claim 1 , wherein the first plurality of land areas in the first array or the second plurality of apertures in the second array form a discrete pattern.

10 . The patterned apertured web of claim 1 , wherein the first plurality of apertures in the first array or the second plurality of apertures in the second array form a linear pattern.

11 . An absorbent article comprising the patterned apertured web of claim 1 .

12 . The absorbent article of claim 11 , wherein the first zone forms a first region of a topsheet or an outer cover, and wherein the second zone forms a second, different region of the topsheet or the outer cover.

13 . The absorbent article of claim 11 , wherein the first zone or the second zone indicate the correct orientation of the absorbent article on a wearer.

14 . The patterned apertured web of claim 1 , wherein the patterned apertured web comprises a polyethylene/polypropylene bicomponent spunbond material.

15 . The patterned apertured web of claim 1 , wherein the patterned apertured web comprises nanofibers or crimped fibers.

16 . A patterned apertured web comprising:
a plurality of first arrays forming a first zone in the patterned apertured web, wherein at least some of the first arrays comprise:
a first plurality of land areas; and
a first plurality of non-homogeneous apertures, wherein at least some of the first plurality of land areas surround at least some of the first plurality of apertures;
wherein the first plurality of apertures have an Average Absolute Feret Angle of greater than about 20 degrees, according to the Aperture Test herein; and
wherein the first arrays comprises an Effective Open Area in the range of about 5% to about 50%, according to the Aperture Test herein; and
a plurality of second, different arrays forming a second zone in the patterned aperture web, wherein at least some of the second arrays comprise:
a second plurality of land areas; and
a second plurality of non-homogeneous apertures, wherein at least some of the second plurality of land areas surround at least some of the second plurality of apertures;
wherein the second arrays comprise an Effective Open Area of about 5% to about 50%, according to the Aperture Test herein.

17 . The patterned apertured web of claim 16 , wherein the second plurality of apertures have an Average Absolute Feret Angle of greater than about 20 degrees, according to the Aperture Test herein.

18 . A patterned apertured web comprising:
a layer comprising a plurality of apertures and a plurality of land areas, wherein the plurality of apertures comprise a first set of apertures in a first zone and a second set of apertures in a second zone; wherein the first set of apertures in the first zone have Interaperture Distances, according to the Aperture Test herein, wherein the Interaperture Distances of the first set of apertures have a first distribution having a first mean and a first median, and wherein the first mean is different than the first median; wherein the second set of apertures in the second zone have Interaperture Distances, according to the Aperture Test herein, wherein the Interaperture Distances of the second set of apertures have a second distribution having a second mean and a second median, wherein the second mean is different than the second median, and wherein the first and second sets of apertures have different patterns.

19 . The patterned apertured web of claim 18 , wherein the layer is a first layer, comprising a second layer.

20 . The patterned apertured web of claim 19 , wherein the second layer is not apertured.

21 . The patterned apertured web of claim 19 , wherein the second layer comprises a second plurality of apertures and a second plurality of land areas.

22 . An absorbent article comprising the patterned apertured web of claim 18 .
