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.
