Abstract
A nonwoven fabric is disclosed. The nonwoven fabric can include a first surface and a second surface and at least a first visually discernible zone 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 the first visually discernible zone can exhibit a high visual resolution.
Claims20
A package comprising a plurality of disposable absorbent articles, wherein each disposable absorbent article includes a nonwoven fabric, wherein each nonwoven fabric comprises a first surface and a second surface, and at least a first visually discernible zone on at least one of the first surface and the second surface, the first visually discernable 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 the first visually discernable zones of the nonwoven fabrics of the plurality of disposable articles of the package have a Gray Level Variation of between about 0.1 and about 10.0, as measured according to the Inter-Article Gray Level Variation Test Method defined herein;
- wherein the first visually discernable zone on the nonwoven fabric of at least one of the disposable absorbent articles of the package has a Haralick Maximum Mean Contrast Value of between about 80 and about 750, as measured according to the Haralick Maximum Contrast Test Method defined herein.
The package of claim 1, wherein the Haralick Maximum Mean Contrast Value of the first disposable article is greater than 80.
A package comprising a plurality of disposable absorbent articles, wherein each disposable absorbent article includes a nonwoven fabric, wherein each nonwoven fabric comprises a first surface and a second surface, and at least a first visually discernible zone on at least one of the first surface and the second surface, the first visually discernable 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 the intensive property is one or more of:
- a. thickness,
- b. basis weight, and
- c. volumetric density;
- wherein the first visually discernable zones of the nonwoven fabrics of the plurality of disposable articles of the package have a Gray Level Variation of between about 0.1 and about 10.0, as measured according to the Inter-Article Gray Level Variation Test Method defined herein.
The package of claim 44, wherein the Gray Level Variation is between about 0.1 and about 3.0.
The package of claim 44, wherein the Gray Level Variation is less than 1.8.
A package comprising a plurality of disposable absorbent articles, wherein each disposable absorbent article includes a nonwoven fabric, wherein each nonwoven fabric comprises a first surface and a second surface, and at least a first visually discernible zone on at least one of the first surface and the second surface, the first visually discernable 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 the intensive property is one or more of:
- a. thickness,
- b. basis weight, and
- c. volumetric density;
- wherein the first visually discernable zones of the nonwoven fabrics of the plurality of disposable articles of the package have a Gray Level Variation of between about 0.1 and about 10.0, as measured according to the Inter-Article Gray Level Variation Test Method defined herein;
- wherein the first visually discernable zone on the nonwoven fabric of at least one of the disposable absorbent articles of the package has a Haralick Maximum Mean Contrast Value of between about 80 and about 750, as measured according to the Haralick Maximum Contrast Test Method defined herein.
