Abstract

A 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.
