Abstract
A through-air thermally bonded 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 V2 rms, and wherein the first surface has a TS7 value that is higher than the second surface TS7 value.

A through-air bonded nonwoven fabric comprising:
- the through-air bonded 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 V2 rms;
- wherein the intensive property is basis weight;
- 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;
- wherein, in at least one of the microzones, the first and second regions comprise a surfactant;
- and
- wherein a ratio of % surfactant in the first region to % surfactant in the second region is less than 1.
A through-air bonded nonwoven fabric comprising:
- the through-air bonded 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 V2 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;
- 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;
- wherein, in at least one of the microzones, the rust and second regions comprise a surfactant;
- and
- wherein a ratio of % surfactant in the first region to % surfactant in the second region is less than 1.
