Absorbent articles having textured zones

Abstract

An absorbent article comprises a chassis having a belt portion extending therefrom. The belt portion comprises a side edge, a waist opening edge, a leg opening edge, first and second substrates engaged with each other, and elastic elements disposed intermediate the first substrate and the second substrate. The belt portion also comprises a first texture zone comprising a first portion of the substrates and the elastic strands and disposed adjacent to the side edge and the waist opening edge and a second texture zone comprising a second portion of the substrates and the elastic elements and disposed adjacent to the side edge and the leg opening edge. The first texture zone extends at least partially along a first lateral extent of the belt portion and the second texture zone extends at least partially along a second lateral extent of the belt portion.
