Abstract
A nonwoven fabric. 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 the intensive property is one or more of thickness, basis weight, or volumetric density, and wherein the first surface has a TS7 value different than a TS7 value of the second surface.
Claims20
A nonwoven fabric formed of continuous fibers, the nonwoven comprising:
- a first surface on a first side of the nonwoven fabric,
- a second surface on a second side of the nonwoven fabric opposite the first side, and
- a visually discernible zone on the second surface and extending from the first surface, the visually discernible zone having a pattern of three-dimensional features,
- each of the three-dimensional features in the visually discernible zone defining individual microzones, each individual microzone comprising a first region and a second region visually distinct from the first region,
- wherein each first region and each second region extend from the first side of the nonwoven fabric to the second side of the nonwoven fabric,
- wherein the first surface of the nonwoven fabric in each individual microzone has greater fiber to fiber bonding than the second surface of the nonwoven fabric in each individual microzone, and
- wherein a minimally-bonded portion of the second surface of the nonwoven fabric in the second region of each individual microzone has little fiber to fiber bonding,
- the first and second regions in each individual microzone having a difference in values for an intensive property;
- wherein the nonwoven fabric is not formed from separate layers.

- wherein each first region and each second region extend from the first side of the nonwoven fabric to the second side of the nonwoven fabric,
- wherein the first surface of the nonwoven fabric in each individual microzone has greater fiber to fiber bonding than the second surface of the nonwoven fabric in each individual microzone, and
- wherein a minimally-bonded portion of the second surface of the nonwoven fabric in the second region of each individual microzone has little fiber to fiber bonding,
- wherein the first regions and the second regions in each individual microzone have different values for basis weight;
- wherein the basis weight of every first region and of every second region is greater than zero;
- and
- wherein the nonwoven fabric is not formed from separate layers.
