Abstract
An absorbent article is disclosed, including a three-dimensional material formed of a liquid permeable topsheet and an acquisition material. The acquisition material is positioned beneath the topsheet, and both may be formed of nonwoven material. The three dimensional material may have two surfaces and a plurality of protrusions extending in a z-direction from one of the surfaces, each protrusion having side walls defining an opening in the other of the surfaces. One of the topsheet and the acquisition material may include fibers spun of polymer resin pigmented with a first color that differs from a second color of fibers of the other of the topsheet and the acquisition material, and the differing colors are visible when viewing a wearer-facing surface of the absorbent article.
