Abstract

A nonwoven fabric is provided. 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, wherein at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms, and wherein the first surface has a TS7 value that is higher than the second surface TS7 value.

Claims (29)

1. A spunbond nonwoven fabric comprising:

a first surface, a second surface, and a visually discernible zone on at least one of the first surface and second surface, the visually discernible zone having a 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 at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms;

wherein the intensive property is basis weight; and

wherein the difference in values for the basis weight for the first region and the second region is from about 1.2× to about 10× different.

2. The spunbond nonwoven fabric of claim 1 , wherein the first surface has a TS7 value of about 2 dB V 2 rms 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.

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

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

5. The spunbond nonwoven fabric of claim 1 , wherein the second surface has a TS7 value of about 3 dB V 2 rms to about 8 dB V 2 rms, and wherein the first surface has a TS7 value different than the TS7 value of the first surface.

6. The spunbond nonwoven fabric of claim 1 , 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.

7. The spunbond nonwoven fabric of claim 6 , wherein the Contact Angle is between about 90 degrees and about 140 degrees, as measured by the Contact Angle Test Method.

8. The spunbond nonwoven fabric of claim 6 , wherein the Contact Angle is between about 110 degrees and about 135 degrees, as measured by the Contact Angle Test Method.

9. The spunbond 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 10 seconds, as measured by the Time to Wick Test Method.

10. The spunbond nonwoven fabric of claim 9 , wherein the Time to Wick is between about 10 seconds and about 60 seconds, as measured by the Time to Wick Test Method.

11. The spunbond nonwoven fabric of claim 1 , wherein e basis weight of every region is greater than zero.

12. An absorbent article comprising a spunbond nonwoven fabric of claim 1 .

13. The absorbent article of claim 12 , wherein the absorbent article comprises a topsheet, a backsheet, and an absorbent core positioned intermediate the topsheet and the backsheet.

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

15. A package of absorbent articles, each absorbent article comprising the spunbond nonwoven fabric of claim 1 , 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.

16. A spunbond nonwoven fabric comprising:

a first surface, a second surface, and a visually discernible zone on at least one of the first surface and second surface, the visually discernible zone having a 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 at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms, and wherein the first surface has a TS7 value that is higher than the second surface TS7 value;

wherein the intensive property is basis weight; and

wherein the difference in values for the basis weight for the first region and the second region is from about 1.2× to about 10× different, and wherein the basis weight of the first region and the second region are both greater than zero.

17. The spunbond nonwoven fabric of claim 16 , wherein the first surface has a TS7 value of about 2 dB V 2 rms to about 12 dB V 2 rms, and wherein the second surface has a TS7 value of about 3 dB V 2 rms to about 8 dB V 2 rms.

18. A spunbond nonwoven fabric comprising:

a first surface, a second surface, and a visually discernible zone on at least one of the first surface and second surface, the visually discernible zone having a 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 at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms, and wherein the first surface has a TS7 value that is different than the second surface TS7 value;

wherein the intensive property is basis weight; and

wherein the difference in values for the basis weight for the first region and the second region is from about 1.2× to about 10× different, and wherein the basis weight of the first region and the second region are both greater than zero.

19. An absorbent article comprising a spunbond nonwoven fabric of claim 18 .

20. A package of absorbent articles, each absorbent article comprising a spunbond nonwoven fabric of claim 18 , 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.
