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 exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method detailed herein.

First claim

What is claimed is:

1 . A nonwoven fabric comprising:
a. a first surface and a second surface, and at least a first and second visually discernible zones on at least one of the first and second surface, each of the first and second zones having a visually different pattern of three-dimensional features that each comprise at least two distinct three-dimensional features, each of the patterns of three-dimensional features defining a microzone comprising a first region and a second region that correspond to the at least two distinct three-dimensional features; b. wherein values for an intensive property for the first region and the second region of the microzone in the first zone are different, wherein values for the intensive property for the first region and the second region of the microzone in the second zone are different, and wherein the intensive property is thickness; C. wherein the first surface has a TS7 value that is different than a TS7 value of the second surface; and d. wherein the nonwoven is a through air bonded nonwoven.

2 . The nonwoven fabric of claim 1 , wherein at least one of the microzones exhibits a Contact Angle in the range of about 90 degrees to about 140 degrees, as measured by the Contact Angle Test Method.

3 . The nonwoven fabric of claim 1 , wherein at least one of the microzones exhibits a Contact Angle in the range of about 110 degrees to about 135 degrees, as measured by the Contact Angle Test Method.

4 . The nonwoven fabric of claim 1 , wherein at least one of the microzones exhibits a Contact Angle in the range of about 125 degrees to about 135 degrees, as measured by the Contact Angle Test Method.

5 . The nonwoven fabric of claim 1 , wherein the first region exhibits both a Contact Angle of greater than about 90 degrees and a Time to Wick of greater than about 10 seconds, as measured by the Time to Wick Test Method.

6 . The nonwoven fabric of claim 5 , wherein the Time to Wick is between about 10 seconds and about 60 seconds, as measured by the Time to Wick Test Method.

7 . The nonwoven fabric of claim 1 , wherein the thickness of every region is greater than zero.

8 . The nonwoven fabric of claim 1 , wherein the difference in thickness in the first zone is greater than about 25 microns.

9 . The nonwoven fabric of claim 1 , wherein the first surface has a TS7 value that is higher than the second surface TS7 value.

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

11 . The absorbent article of claim 10 , wherein the nonwoven fabric forms a portion of a topsheet.

12 . A nonwoven fabric comprising:
a. a first surface and a second surface, and at least a first and second visually discernible zones on at least one of the first and second surface, each of the first and second zones having a visually different pattern of three-dimensional features that each comprise at least two distinct three-dimensional features, each of the patterns of three-dimensional features defining a microzone comprising a first region and a second region that correspond to the at least two distinct three-dimensional features; b. wherein values for an intensive property for the first region and the second region of the microzone in the first zone are different, wherein values for the intensive property for the first region and the second region of the microzone in the second zone are different, and wherein the intensive property is thickness; c. wherein the first surface has a TS7 value that is higher than a TS7 value of the second surface; and d. wherein the nonwoven is a through air bonded nonwoven.

13 . An absorbent article comprising the nonwoven fabric of claim 11 .

14 . The absorbent article of claim 13 , wherein the nonwoven fabric is a topsheet.

15 . The nonwoven fabric of claim 12 , wherein the difference in thickness in the first zone is greater than about 25 microns.

16 . A nonwoven fabric comprising:
a. a first surface and a second surface, and at least a first and second visually discernible zones on at least one of the first and second surface, each of the first and second zones having a visually different pattern of three-dimensional features that each comprise at least two distinct three-dimensional features, each of the patterns of three-dimensional features defining a microzone comprising a first region and a second region that correspond to the at least two distinct three-dimensional features; b. wherein values for an intensive property for the first region and the second region of the microzone in the first zone are different, wherein values for the intensive property for the first region and the second region of the microzone in the second zone are different, and wherein the intensive property is thickness; c. wherein the first surface has a TS7 value of about 2 dB V2 to about 12 dB V2 rms, and wherein the second surface has a TS7 value different than the TS7 value of the first surface; d. wherein the nonwoven is a through air bonded nonwoven.

17 . An absorbent article comprising the nonwoven fabric of claim 16 .

18 . The absorbent article of claim 17 , wherein the nonwoven fabric forms a portion of a topsheet.

19 . The nonwoven fabric of claim 16 , wherein the difference in thickness in the first zone is greater than about 25 microns.

20 . The nonwoven fabric of claim 16 , wherein the first surface has a TS7 value that is higher than the second surface TS7 value.
