A patterned chemical fiber substrate having a plurality of individual fibers, a first region, and a second region is provided. The plurality of individual fibers comprise a functional surface additive. The plurality of individual fibers of the first region have a first diameter and the plurality of individual fibers of the second region have a second diameter. The first diameter is smaller than the second diameter. The first region has a first C.I.E.L * fraction and the second region has a second C.I.E.L * fraction. The first C.I.E.L * score is different from the second C.I.E.L * score. 提供了具有多根单独纤维、第一区域和第二区域的图案化纤维基底。该多根单独纤维包含功能性表面添加剂。第一区域的多根单独纤维具有第一直径，并且第二区域的多根单独纤维具有第二直径。第一直径小于第二直径。第一区域具有第一C.I.E.L*分数，并且第二区域具有第二C.I.E.L*分数。第一C.I.E.L*分数不同于第二C.I.E.L*分数。
