Abstract
Patterned fibrous substrates having a plurality of individual fibers, a first region, and a second region are provided. The first region is visually discernable from the second region. The first region has a first region fluid permeability score (PS1), and the second region has a second region fluid permeability score (PS2). The first region fluid permeability score (PS1) is different than the second region fluid permeability score (PS2). The first region fluid permeability score (PS1) and the second region fluid permeability score (PS2) are both greater than 5 Darcy.
Claims22
A patterned fibrous substrate comprising a plurality of individual fibers, a first region, and a second region;
- wherein the first region is visually discernable from the second region;
- wherein a plurality of individual fibers disposed in the first region have a first cross-sectional shape, wherein a plurality of individual fibers disposed in the second region have a second cross-sectional shape;
- wherein the first cross-sectional shape is different than the second cross-sectional shape;
- wherein the first region has a first region fluid permeability score (PS1), according to the Fluid Permeability Test Method;
- wherein the second region has a second region fluid permeability score (PS2), according to the Fluid Permeability Test Method;
- wherein the first region fluid permeability score (PS1) is different than the second region fluid permeability score (PS2):
- and wherein the first region fluid permeability score (PS1) and the second region fluid permeability score (PS2) are both greater than 5 Darcy;
- wherein the first region has a first region opacity, according to the Opacity Test Method, wherein the second region has a second region opacity, according to the Opacity Test Method, and wherein a difference between the first region opacity and the second region opacity is between about 5% and 60%, according to the Opacity Test Method.
A patterned fibrous substrate comprising a plurality of individual
