Shaped nonwoven
A spunbond nonwoven fabric. The fabric has a first surface and a second surface and at least a first and second visually discernible zone on at least one of the first and second surface, each of the first and second zones having a pattern of three-dimensional features, each of the three-dimensional features defining a microzone. Each microzone has a first region and a second region, the first and second regions having a difference in values for an intensive property, and wherein the difference in values for an intensive property for at least one of the microzones in the first zone is different from the difference in values for the intensive property for at least one of the microzones in the second zone.
1. A spunbond nonwoven fabric comprising:
a. a first surface and a second surface and at least a first and second visually discernible zone on at least one of the first and second surface, each of the first and second zones 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 basis weight, and
b. wherein the difference in values for basis weight for at least one of the microzones in the first zone is different from the difference in values for basis weight for at least one of the microzones in the second zone,
wherein the basis weight of every region of the spunbond nonwoven fabric is greater than zero.
2. The spunbond nonwoven fabric of claim 1 , wherein the difference in basis weight values for one of the microzones in the first zone is 1.2× different from the difference in basis weight values for the at least one of the microzones in the second zone.
3. The spunbond nonwoven fabric of claim 1 , wherein the difference in basis weight values for one of the microzones in the first zone is 1.2× to 10× different from the difference in basis weight values for the at least one of the microzones in the second zone.
4. The spunbond nonwoven fabric of claim 1 , wherein the difference in basis weight values for the at least one of the microzones in the first zone is between 3× and 50× different from the difference in basis weight values for the at least one of the microzones in the second zone.
5. The spunbond fabric of claim 1 , wherein fibers of the fabric are thermally bonded at the second regions on the first surface.
6. The spunbond fabric of claim 1 , wherein fibers of the fabric are thermally bonded by point bonds within an area selected from the first region, the second region, or a combination thereof.
7. The spunbond fabric of claim 1 , wherein fibers of the fabric are thermally bonded at the second regions on the first surface and wherein the second regions are fluid permeable.
8. The spunbond fabric of claim 1 , wherein fibers of the fabric are thermally bonded at the second regions on the first surface and wherein the second regions are fluid permeable and wherein fibers of the fabric are thermally bonded with point bonds within an area selected from the first region, the second region, or a combination thereof.
