Abstract

A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, and wherein in at least one of the microzones, the first region is hydrophobic and the second region is hydrophilic.

Claims (36)

1. A nonwoven fabric comprising a first surface and a second opposing surface and first and second visually discernible zones on one of the first or second surfaces, wherein the first visually discernible zone is free of overlap with the second visually discernible zone, each of the first and second zones having a visually different pattern of three-dimensional features, each of the three-dimensional features defining a microzone comprising a first region and a second region, the first and second regions having a difference in values for an intensive property, wherein the intensive property is one or more of:

a. thickness,

b. basis weight, and

c. volumetric density; and

wherein in at least one of the microzones the first region is hydrophobic and the second region is hydrophilic, wherein the first surface has a first TS7 value, wherein the second surface has a second TS7 value, and wherein the first TS7 value is different than the second TS7 value.

2. The nonwoven fabric of claim 1 , wherein the difference in values for the intensive property for one of the microzones in the first zone is an order of magnitude different from the difference in values for at least one of the microzones in the second zone.

3. The nonwoven fabric of claim 1 , wherein the difference in values for the intensive property for one of the microzones in the first zone is from about 1.2× to about 10× different from the difference in values for at least one of the microzones in the second zone.

4. The nonwoven fabric of claim 1 , wherein the intensive property is thickness, and wherein the thickness of every region is greater than zero.

5. The nonwoven fabric of claim 4 , wherein the difference in thickness in the first zone is greater than about 25 microns.

6. The nonwoven fabric of claim 1 , wherein the intensive property is basis weight, and wherein the basis weight of every region is greater than zero.

7. The nonwoven fabric of claim 6 , wherein the difference in basis weight in the first zone is greater than about 5 gsm.

8. The nonwoven fabric of claim 1 , wherein the intensive property is volumetric density, and wherein the volumetric density of every region is greater than zero.

9. The nonwoven fabric of claim 8 , wherein the difference in volumetric density in the first zone is greater than about 0.042 g/cc.

10. The nonwoven fabric of claim 1 , wherein at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms.

11. The nonwoven fabric of claim 10 , wherein the first surface has a TS7 value of about 2 to about 12 dB V 2 rms, and wherein the second surface has a TS7 value different than the TS7 value of the first surface.

12. The nonwoven fabric of claim 11 , wherein the second surface has a TS7 value that is lower than the first surface TS7 value.

13. The nonwoven fabric of claim 10 , wherein the second surface has a TS7 value of about 3 to about 8, and wherein the first surface has a TS7 value different than the TS7 value of the first surface.

14. The nonwoven fabric of claim 13 , wherein the first surface has a TS7 value that is higher than the second surface TS7 value.

15. An absorbent article comprising the nonwoven fabric of claim 1 .

16. A package of the absorbent articles of claim 15 .

17. The package of claim 16 , wherein the package has an in-bag stack height of between about 70 mm and about 100 mm, according to the In-Bag Stack Height Test herein.

18. The nonwoven fabric of claim 1 , wherein the nonwoven fabric is a spunbond construction.

19. A nonwoven fabric comprising a first surface and a second opposing surface and first and second visually discernible zones on one of the first or second surfaces, wherein the first visually discernible zone is free of overlap with the second visually discernible zone, each of the first and second zones having a visually different pattern of three-dimensional features, each of the three-dimensional features defining a microzone comprising a first region and a second region, the first and second regions having a difference in values for an intensive property, wherein the intensive property is one or more of:

a. thickness,

b. basis weight, and

c. volumetric density; and

wherein in at least one of the microzones the first region is hydrophobic and the second region is hydrophilic;

wherein the first surface has a TS7 value of about 2 to about 12 dB V 2 rms; and

wherein the second surface has a TS7 value different than the TS7 value of the first surface.

20. A nonwoven fabric comprising a first surface and a second opposing surface and first and second visually discernible zones on one of the first or second surface, wherein the first visually discernible zone is free of overlap with the second visually discernible zone, each of the first and second zones having a visually different pattern of three-dimensional features, each of the three-dimensional features defining a microzone comprising a first region and a second region, the first and second regions having a difference in values for an intensive property, wherein the intensive property is one or more of:

a. thickness,

b. basis weight, and

c. volumetric density; and

wherein in at least one of the microzones the first region is hydrophobic and the second region is hydrophilic;

wherein a package of absorbent articles each comprising the nonwoven fabric has an in-bag stack height of between about 70 mm and about 100 mm, according to the In-Bag Stack Height Test, wherein the first surface has a first TS7 value, wherein the second surface has a second TS7 value, and wherein the first TS7 value is different that the second TS7 value.

21. The nonwoven fabric of claim 20 , wherein the first zone at least partially surrounds the second zone.
