Abstract

A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.

Claims (50)

1. A patterned apertured web comprising:

a plurality of land areas in the patterned apertured web; and

a plurality of apertures defined in the patterned apertured web, wherein at least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures;

wherein the patterned apertured web has an Effective Open Area in the range of about 5% to about 40%, according to an Aperture Test;

wherein the plurality of apertures are non-homogeneous in a repeat unit such that at least two apertures of the plurality of apertures have a different size, a different shape, or a different Absolute Feret Angle, according to the Aperture Test;

wherein the patterned apertured web comprises spunbond fibers;

wherein the spunbond fibers comprise polypropylene;

wherein the patterned apertured web comprises a portion of a topsheet or a portion of a garment-facing surface;

wherein at least some apertures of the plurality of apertures form a first enclosed shape, wherein a perimeter of the enclosed shape defines a concavity, and wherein the enclosed shape comprises at least six apertures of the plurality of apertures;

wherein at least some apertures of the plurality of apertures form a second enclosed shape, the second enclosed shape being different from the first enclosed shape; and

wherein the first enclosed shape is positioned within and completely surrounded by the second enclosed shape.

2. The patterned apertured web of claim 1 , wherein the patterned apertured web comprises at least two layers, and wherein the at least two layers comprise a first spunbond layer and a second spunbond layer.

3. The patterned apertured web of claim 2 , wherein the first layer has a first basis weight, wherein the second layer has a second basis weight, and wherein the first basis weight is substantially the same as the second basis weight.

4. The patterned apertured web of claim 2 , wherein the first layer has a first basis weight, wherein the second layer has a second basis weight, and wherein the first basis weight is different than the second basis weight.

5. The patterned apertured web of claim 2 , comprising a third layer.

6. The patterned apertured web of claim 2 , comprising a third spunbond layer.

7. A diaper comprising:

a) patterned apertured web of claim 1 ;

b) a backsheet;

c) an absorbent core positioned at least partially intermediate the patterned apertured web and the backsheet; and

d) a pair of leg cuffs.

8. The patterned apertured web of claim 1 , wherein the perimeter of the enclosed shape defines a point where the concavity ends.

9. The patterned apertured web of claim 1 , wherein the second layer has a different hydrophobicity than the first layer.

10. A patterned apertured web comprising:

a plurality of land areas in the patterned apertured web; and

a plurality of apertures defined in the patterned apertured web, wherein at least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures;

wherein the plurality of apertures are non-homogeneous in a repeat unit such that at least two apertures of the plurality of apertures have a different size, a different shape, or a different Absolute Feret Angle, according to an Aperture Test;

wherein the patterned apertured web has an Effective Open Area in a range of about 3% to about 15%, according to the Aperture Test;

wherein the patterned apertured web comprises spunbond fibers comprising polypropylene;

wherein the patterned apertured web comprises a portion of a topsheet or a portion of a garment-facing surface;

wherein at least some apertures of the plurality of apertures form a first enclosed shape, and wherein at least some apertures of the plurality of apertures form a second enclosed shape, the second enclosed shape being different from the first enclosed shape; and

wherein the first enclosed shape is positioned within and completely surrounded by the second enclosed shape.

11. The patterned apertured web of claim 10 , comprising at least two layers, wherein the at least two layers comprise a first spunbond layer and a second spunbond layer.

12. The patterned apertured web of claim 11 , comprising a third spunbond layer.

13. The patterned apertured web of claim 11 , wherein the second spunbond layer has a different hydrophobicity than the first spunbond layer.

14. The patterned apertured web of claim 10 , wherein the first enclosed shape is a heart shape comprising at least six apertures of the plurality of apertures.

15. The patterned apertured web of claim 14 , wherein the second enclosed shape is a diamond.

16. A patterned apertured web comprising:

a plurality of land areas in the patterned apertured web; and

a plurality of apertures defined in the patterned apertured web, wherein at least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures;

wherein the plurality of apertures are non-homogeneous in a repeat unit such that at least two apertures of the plurality of apertures have a different size or a different shape;

wherein the patterned apertured web has an Effective Open Area in the range of about 8% to about 35%, according to an Aperture Test;

a first spunbond layer;

a second spunbond layer;

a third spunbond layer;

wherein the spunbond layers comprise polypropylene;

wherein at least some apertures of the plurality of apertures form a heart shape;

wherein at least some apertures of the plurality of apertures form a second enclosed shape, the second enclosed shape being different from the heart shape; and

wherein the heart shape is positioned within and completely surrounded by the second enclosed shape.

17. The patterned apertured web of claim 16 , wherein the second enclosed shape forms a diamond shape, and wherein at least some apertures of the plurality of apertures have an Effective Aperture Area in a range of about 0.5 mm 2 to about 8.0 mm 2 , according to the Aperture Test.
