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 is hydrophobic and the second region is hydrophilic.
Claims20
A nonwoven fabric comprising a first surface and a second opposing surface and first and second visually discernible zones on one of the first or second surfaces, wherein the first visually discernible zone is free of overlap with the second visually discernible zone, wherein the first zone is positioned adjacent to the second zone, each of the first and second zones having a visually different 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;
- and
- wherein the intensive property is greater than zero, wherein the first region or the second region comprises a curvilinear portion, wherein the curvilinear portion comprises a linear element having at any point along its length a tangential vector V, with a closed shape being such that the tangential vector V has both machine direction and cross direction components that change values over greater than 50% of the length of the linear element of the closed figure, wherein the first surface has a first TS7 value, wherein the second surface has a second TS7 value, and wherein the first TS7 value is different than the second TS7 value.
A nonwoven fabric comprising a first surface and a second opposing surface and first and second visually discernible zones on one of the first or second surfaces, wherein the first visually discernible zone is free of overlap with the second visually discernible zone, wherein the first zone is positioned adjacent to the second zone, each of the first and second zones having a visually different 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;
- and
- wherein the intensive property is greater than zero, wherein the first region or the second region comprises a curvilinear portion, wherein the curvilinear portion comprises a linear element having at any point along its length a tangential vector V, with a closed shape being such that the tangential vector V has both machine direction and cross direction components that change values over greater than 50% of the length of the linear element of the closed figure, wherein the first surface has a TS7 value of about 2 to about 12 dB V2 rms, and wherein the second surface has a TS7 value different than the TS7 value of the first surface.
A through air bonded nonwoven fabric comprising a first surface and a second opposing surface and first and second visually discernible zones on one of the first or second surfaces, wherein the first visually discernible zone is free of overlap with the second visually discernible zone, wherein the first zone is positioned adjacent to the second zone, each of the first and second zones having a visually different 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 basis weight, and wherein the basis weight is greater than zero;
- wherein the first region or the second region comprises a curvilinear portion, wherein the curvilinear portion comprises a linear element having at any point along its length a tangential vector V, with a closed shape being such that the tangential vector V has both machine direction and cross direction components that change values over greater than 50% of the length of the linear element of the closed figure, wherein the first surface has a first TS7 value, wherein the second surface has a second TS7 value, and wherein the first TS7 value is different that the second TS7 value.
