Abstract

This invention relates to a novel absorbent structure and absorbent products containing this absorbent structure. More particularly, the absorbent structure of this invention contains a high-loft, bulky, low-density cover layer (10), a higher density transfer layer (20), a very high density, retentive reservoir layer (30) and an impermeable barrier layer (70). The cover and barrier layers are sealed around their periphery and, preferably, all the layers are bonded to each other to form a unitized structure.
