Absorbent article with bonded web material

摘要

An absorbent article to be worn the lower torso is provided. The absorbent article comprises a chassis comprising a topsheet, a backsheet, an absorbent core, and a pair of longitudinal barrier cuffs attached to the chassis. Each of the longitudinal barrier cuffs comprises a web of material. The web of material comprises a first nonwoven component layer, and a second nonwoven component layer. Each of the longitudinal barrier cuffs comprises a longitudinal zone of attachment where each of the longitudinal barrier cuff attaches to the chassis, a longitudinal free edge, and a plurality of mechanical bonds disposed between the longitudinal zone of attachment and the free edge. The plurality of mechanical bonds attach one of a first portion of the web of material to a second portion of the web of material, and the web of material to a portion of the absorbent article.
