Abstract

An absorbent article comprises a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core positioned at least partially intermediate the topsheet and the backsheet, and a distribution material comprising a wet-laid, three-dimensional fibrous substrate comprising at least 80% pulp fibers by weight of the wet-laid, three-dimensional fibrous substrate. The wet-laid, three-dimensional fibrous substrate comprises a continuous network region and a plurality of discrete zones that are dispersed throughout the continuous network region. The continuous network region comprises a first average density and the plurality of discrete zones comprise a second average density. The discrete zones are dispersed throughout the continuous network region. The first average density and the second average density are different.
