Abstract

A nonwoven web for an absorbent article is provided. The nonwoven web comprises a first surface, a second surface, and a visually discernible pattern of three-dimensional features on the first surface or the second surface. The three-dimensional features comprise one or more first regions and a plurality of second regions. The one or more first regions have a first value of an average intensive property. The plurality second regions have a second value of the average intensive property. The first value and the second value are different and are both greater than zero. The nonwoven web has a Single Layer Chroma value in the range of about 1.0 to about 3.5, according to the Delta Chroma and Single Layer Chroma Test. The nonwoven web has a Delta Chroma value in the range of about +0.1 to about +3.5, according to the Delta Chroma and Single Layer Chroma Test.

First claim

a visually discernible pattern of three-dimensional features on the first surface or the second surface, wherein the three-dimensional features comprise one or more first regions and a plurality of second regions;
wherein the one or more first regions have a first value of an average intensive property, wherein the plurality second regions have a second value of the average intensive property, wherein the first value and the second value are different, wherein the first value and the second value are greater than zero, and wherein the average intensive property is basis weight, volumetric density, or caliper;
wherein a non-white colorant is included in a composition used to create fibers of the non-woven web such that the non-woven web appears white to a human eye, wherein the composition includes 0.15% to 0.4% by weight of the non-white colorant;
wherein the nonwoven web has a Single Layer Chroma value in the range of about 1.0 to about 3.5, according to the Delta Chroma and Single Layer Chroma Test; and
wherein the nonwoven web has a Delta Chroma value in the range of about +0.1 to about +3.5, according to the Delta Chroma and Single Layer Chroma Test.

2. The nonwoven web for an absorbent article of claim 1 , wherein the nonwoven web has a Single Layer Chroma value in the range of about 1.5 to about 3.5, according to the Delta Chroma and Single Layer Chroma Test, and wherein the nonwoven web has a Delta Chroma value in the range of about +0.5 to about +3.5, according to the Delta Chroma and Single Layer Chroma Test.

3. The nonwoven web for an absorbent article of claim 1 , wherein the nonwoven web has a Single Layer Chroma value in the range of about 1.5 to about 3.5, according to the Delta Chroma and Single Layer Chroma Test, and wherein the nonwoven web has a Delta Chroma value in the range of about +1.0 to about +3.5, according to the Delta Chroma and Single Layer Chroma Test.

4. The nonwoven web for an absorbent article of claim 1 , wherein the nonwoven web has a Single Layer Chroma value in the range of about 1.5 to about 3.5, according to the Delta Chroma and Single Layer Chroma Test, and wherein the nonwoven web has a Delta Chroma value in the range of about +1.5 to about +3.5, according to the Delta Chroma and Single Layer Chroma Test.

5. The nonwoven web for an absorbent article of claim 1 , wherein the non-white colorant comprises a blue colorant.

6. The nonwoven web for an absorbent article of claim 1 , wherein the first average intensive property and the second average intensive property are basis weight.

7. The nonwoven web for an absorbent article of claim 1 , wherein the first average intensive property and the second average intensive property are caliper.

8. The nonwoven web for an absorbent article of claim 1 , wherein the first average intensive property and the second average intensive property are volumetric density.

9. The nonwoven web for an absorbent article of claim 1 , wherein the nonwoven web comprises bonds at fiber intersections formed by passing hot air through the nonwoven web.

10. The nonwoven web for an absorbent article of claim 1 , wherein the nonwoven web comprises calendar bonds configured to join the fibers together.

11. The nonwoven web for an absorbent article of claim 1 , wherein the nonwoven web comprises a second, visually discernible pattern of three-dimensional features on the first surface or the second surface, wherein the three-dimensional features comprise one or more third regions and a plurality of fourth regions, and wherein the one or more third regions are different than the plurality of fourth regions in a value of an average intensive property.

12. The nonwoven web for an absorbent article of claim 1 , wherein the nonwoven web comprises multicomponent fibers, and wherein at least one component of the multicomponent fibers is bio-based.

13. The nonwoven web for an absorbent article of claim 1 , wherein the nonwoven web has a basis weight in the range of about 10 gsm to about 100 gsm according to the Basis Weight Test, and wherein the nonwoven web is a spunbond nonwoven web.

14. The nonwoven web for an absorbent article of claim 1 , wherein a portion of the nonwoven web 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 wherein the portion of the nonwoven web has a TS750 value in the range of about 6 dB V 2 rms to about 30 dB V 2 rms, according to the Emtec Test.

15. The nonwoven web for an absorbent article of claim 14 , wherein the portion of the nonwoven web has a D value in the range of about 2 mm/N to about 6 mm/N, according to the Emtec Test.

16. An absorbent article comprising the nonwoven web of claim 1 .

17. A nonwoven web for an absorbent article, the nonwoven web having one or more layers and comprising:
a first surface;
a second surface;
a plurality of continuous spunbond fibers; and
a visually discernible pattern of three-dimensional features on the first surface or the second surface, wherein the three-dimensional features comprise one or more first regions and a plurality of second regions;
wherein the one or more first regions have a first value of an average intensive property, wherein the plurality of second regions have a second value of the average intensive property, wherein the first value and the second value are different, wherein the first value and the second value are greater than zero, and wherein the average intensive property is basis weight, volumetric density, or caliper;
wherein a non-white colorant is included in a composition used to create fibers of the non-woven web such that the non-woven web appears white to a human eye, wherein the composition includes 0.15% to 0.4% by weight of the non-white colorant;
