Abstract
An absorbent article is disclosed which exhibits enhanced wicking capacity. The absorbent article includes a liquid-permeable cover, a liquid-impermeable baffle and an absorbent enclosed therebetween. The absorbent is constructed of first, second and third members. Each member has a wicking capacity for body fluids discharged by a human body. The first member has a high wicking capacity, the second member has a lower wicking capacity than the first member, and the third member has a greater wicking capacity than the second member. The different wicking capacities of the three members promotes a systematic distribution of body fluid away from the body-side cover down into the absorbent article. The second member also has an equal or greater width than either the first or third members so as to provide a visual cue of when the absorbent article is in need of changing. By changing the absorbent article when the second member appears to be soiled, the user can prevent side leakage and soiling of an adjacent undergarment.
