Abstract
Abstract An absorbent article is disclosed which contains an absorbent positioned between a fluid permeable cover and a fluid-impermeable baffle. The baffle can be either a nonwoven web or have a nonwoven web secured to it. The nonwoven web hs a high coefficient of friction so as to hold the absorbent article stationary relative to an adjacent undergarment and thereby retain the absorbent article in a comfortable position relative to the body of the user. The nonwoven web is a dry, soft, non-tacky, fibrous material which can have an elastomeric component. The nonwoven web can partially or totally cover the exterior surface of the absorbent article which is away from the body of the user.
