Abstract
Abstract A bodyside cover an for absorbent article is disclosed which includes two different materials to provide enhanced functionality. The bicomponent cover includes an apertured first material, which is positioned along the longitudinal central axis of the absorbent article, and a nonperforated second material secured to at least a portion of the first material. The first material has a rewet value which is less than, or equal to, the rewet value of the second material while the second material is softer than the first material. The first material is positioned below the principal point of fluid discharge and represents the primary fluid-receiving region of the cover. The second material is situated away from the principal point of fluid discharge and represents the secondary fluid-receiving region of the cover.
