Abstract: A composite absorbent article has a plural layer absorbent core comprising a bonded insert pad (14) and a dispersion pad (16). The insert pad (14) preferably comprises binder coated fibers to which superabsorbent particles are adhered. By using heat fusible binders, a heat bonded superabsorbent containing insert pad (14) is provided. The dispersion pad (16) also typically comprises fibers and enhances the wicking of liquid throughout the insert pad (14). In addition, the insert pad (14) may be bound to the dispersion pad (16) at the inerface between the pads to provide a stronger composite structure and to also entangle the fibers of the two pads at their interface to improve the wicking of liquid from the dispersion pad into the insert pad. The insert pad (14) is preferably positioned underneath the facing sheet (12) of the diaper (10) with the dispersion pad (16) being positioned between the insert pad (14) and the backing sheet (18) of the diaper (10).
