Patent

CA 2139382

There is provided by this invention at least three integrated regions, each region having distinct density and fluid affinity gradients, wherein the density and fluid affinity of the composite continuously increases from top to bottom thereby facilitating effective fluid transport and efficient utilization of storage capacity. An additional layer of SA and tissue may be provided to the absorbent product to provide an absorbent structure with dry feel and low stain. Methods of forming integrated, multi-layered absorbent composites and structures comprising at least three regions wherein each region has distinct density and fluid affinity gradients and wherein the density and fluid affinity of the composite continuously increases from top to bottom, are also provided herein.
