Method for making a shaped nonwoven
A nonwoven fabric comprises a first surface, a second surface, and a visually discernible pattern on at least one of the first and second surfaces. The visually discernible pattern has a regular, repeating pattern of three-dimensional features. Each of the three-dimensional features define a microzone comprising a first region and a second region. The first and second regions having a difference in values for an intensive property. The first surface has a TS7 value in the range of about 1 dB V 2 rms to about 15 dB V 2 rms. The second surface has a TS7 value in the range of about 1 dB V 2 rms to about 15 dB V 2 rms. A ratio of the TS7 value of the first surface to the TS7 value of the second surface is in the range of about 1 to about 3.
