Abstract
Patterned fibrous substrates having a plurality of individual fibers, a first region, and a second region are provided. The plurality of individual fibers comprise a functional surface additive. A plurality of individual fibers of the first region have a first diameter, and a plurality of individual fibers of the second region have a second diameter. The first diameter is less than the second diameter. The first region has a first C.I.E. L* score, and the second region has a second C.I.E. L* score. The first C.I.E. L* score is different than the second C.I.E. L* score.
Claims22
