  • Patent number: 5401267
    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.
