Abstract
A method for making nonwoven fabric. The nonwoven fabric can include three-dimensional features that 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. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.
Claims20
A nonwoven fabric comprising:
- a first surface;
- a second surface;
- and
- at least two different, visually discernible patterns on at least one of the first and second surfaces, the at least two different, visually discernible patterns each having a regular, repeating 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 or volumetric density;
- wherein the first surface has a TS7 value in the range of about 1 dB V2 rms to about 15 dB V2 rms;
- wherein the second surface has a TS7 value in the range of about dB V2 rms to about 15 dB V2 rms;
- wherein the TS7 value of the first surface is different than the TS7 value of the second surface;
- wherein the nonwoven fabric is air through bonded;
- wherein the nonwoven fabric retains greater than 70% of its original average caliper after being tested by the Compression Aging Test at a pressure of 35 KPa;
- and
- wherein the nonwoven fabric comprises bicomponent fibers.
