Abstract

Shaped, soft, and textured nonwoven fabrics are provided. Absorbent articles that comprise shaped, soft and textured nonwoven fabrics are provided. The nonwoven fabrics may be a topsheet and an outer cover nonwoven material of the absorbent article. A portion of a wearer-facing surface of the topsheet may have a TS7 in the range of about 1 dB V 2 rms of about 1 to about 4.5 dB V 2 rms and a TS750 in the range of about 6 dB V 2 rms to about 30 dB V 2 rms. A portion of a garment-facing surface of the outer cover nonwoven material may have a TS7 in the range of about 1 dB V 2 rms of about 1 to about 4.5 dB V 2 rms and a TS750 in the range of about 6 dB V 2 rms to about 30 dB V 2 rms. The nonwoven fabrics of the present disclosure provide soft materials with texture.

First claim

What is claimed is:

1. A through air bonded nonwoven fabric comprising a surface, the surface having a portion having:
a TS7 value in the range of about 1 dB V 2 rms to about 4.5 dB V 2 rms, according to the Emtec Test;
a TS750 value in the range of about 6 dB V 2 rms to about 15 dB V 2 rms, according to the Emtec Test; and
a D value in the range of about 2 mm/N to about 6 mm/N, according to the Emtec Test;
wherein the surface has a first visually discernible pattern of three-dimensional features, each of the three dimensional features having a first region and a second region, the first region having a different basis weight than the second region;
wherein the surface has a second visually discernible pattern of three-dimensional features, each of the three dimensional features having a first region and a second region, the first region having a different basis weight than the second region; and
wherein a difference in values for basis weight in the first region and the second region in the first visually discernible pattern is different than a difference in values for basis weight in the first region and the second region in the second visually discernible pattern.

2. The through air bonded nonwoven fabric of claim 1 , wherein a basis weight of the through air bonded nonwoven material is in the range of about 20 gsm to about 50 gsm.

3. The through air bonded nonwoven fabric of claim 1 , wherein fibers of the through air bonded nonwoven fabric comprise bicomponent spunbond fibers.

4. The through air bonded nonwoven fabric of claim 1 , wherein the portion of the surface has a total region one area in the range of about 5% to about 25%, of a total area of the portion of the surface, with the remainder of the portion of the surface being a total region two area.

5. The through air bonded nonwoven fabric of claim 1 , wherein the portion of the surface has a total region one area in the range of about 10% to about 20%, of a total area of the portion of the surface with the remainder of the portion of the surface being a total region two area.

6. The through air bonded nonwoven fabric of claim 3 , wherein the nonwoven fabric comprises crimped fibers.

7. An absorbent article comprising the through air bonded nonwoven fabric of claim 1 .

8. The absorbent article of claim 7 , wherein the through air bonded nonwoven fabric forms a portion of a topsheet.

9. The absorbent article of claim 8 , wherein a wearer-facing surface of the topsheet comprises a first region and a second region, and wherein the first region is hydrophobic and the second region is hydrophilic.

10. The absorbent article of claim 7 , wherein the through air bonded nonwoven fabric forms a portion of an outer cover nonwoven material.

11. An absorbent article comprising:
a through air bonded nonwoven fabric topsheet comprising a wearer-facing surface, wherein a portion of the wearer-facing surface has:
a TS7 value in the range of about 1 dB V 2 rms to about 4.5 dB V 2 rms, according to the Emtec Test; and
a TS750 value in the range of about 6 dB V 2 rms to about 15 dB V 2 rms, according to the Emtec Test;
wherein the portion of the wearer-facing surface has a first visually discernible pattern of three-dimensional features, each of the three dimensional features having a first region and a second region, the first region having a different basis weight than the second region;
wherein the portion of the wearer-facing surface has a second visually discernible pattern of three-dimensional features, each of the three dimensional features having a first region and a second region, the first region having a different basis weight than the second region;
wherein a difference in values for basis weight in the first region and the second region in the first visually discernible pattern is different than a difference in values for basis weight in the first region and the second region in the second visually discernible pattern; and

through air bonded outer cover nonwoven material comprising a garment-facing surface, wherein a portion of the garment-facing surface has:
a TS7 value in the range of about 1 dB V 2 rms to about 4.5 dB V 2 rms, according to the Emtec Test; and
a TS750 value in the range of about 6 dB V 2 rms to about 15 dB V 2 rms, according to the Emtec Test; and
wherein the portion of the garment-facing surface has a visually discernible pattern of three-dimensional features, each of the three dimensional features having a first region and a second region, the first region having a different basis weight than the second region.

12. The absorbent article claim 11 , wherein the portion of wearer-facing surface has a D value in the range of about 2 mm/N to about 6 mm/N, according to the Emtec Test.

13. The absorbent article claim 12 , wherein the portion of the garment-facing surface has a D value in the range of about 2 mm/N to about 6 mm/N, according to the Emtec Test.

14. The absorbent article of claim 11 , wherein the portion of the wearer-facing surface has a total region one area in the range of about 5% to about 25% of a total area of the portion of the wearer-facing surface, with the remainder of the portion of the wearer-facing surface being a total region two area.

15. The absorbent article of any one of claim 11 , wherein the portion of the garment-facing surface has a total region one area in the range of about 5% to about 25% of a total area of the portion of the garment-facing surface, with the remainder of the portion of the garment-facing surface being a total region two area.

16. The absorbent article of claim 11 , wherein the topsheet and the outer cover nonwoven material comprise crimped bicomponent spunbond fibers.

17. The absorbent article claim 11 , wherein the wearer-facing surface comprises a first region and a second region, and wherein the first region is hydrophobic and the second region is hydrophilic.

18. An absorbent article comprising:
a through air bonded nonwoven topsheet;
a backsheet;
an absorbent core positioned at least partially intermediate the topsheet and the backsheet; and
a through air bonded nonwoven outer cover joined to the backsheet;
wherein a first portion of a wearer-facing side of the through air bonded nonwoven topsheet and a second portion of a garment-facing side of the through air bonded nonwoven outer cover each have a TS7 value in the range of about 1 dB V 2 rms to about 4.5 dB V 2 rms, according to the Emtec Test;
wherein the first portion of the wearer-facing surface of the through air bonded nonwoven topsheet has a first visually discernible pattern of three-dimensional features, each of the three dimensional features having a first region and a second region, the first region having a different basis weight than the second region;
wherein the first portion of the wearer-facing surface of the through air bonded nonwoven topsheet has a second visually discernible pattern of three-dimensional features, each of the three dimensional features having a first region and a second region, the first region having a different basis weight than the second region;
wherein a difference in values for basis weight in the first region and the second region in the first visually discernible pattern is different than a difference in values for basis weight in the first region and the second region in the second visually discernible pattern; and
wherein the second portion of the garment-facing side of the through air bonded nonwoven outer cover has a TS750 value that is about 1.5 to about 2 times greater than a TS750 value of
