Patent ID: 7081559

Claim:
An absorbent article consisting essentially of an absorbent composite sheet and a liquid blocking back sheet, wherein said absorbent composite sheet comprises: a first layer on a liquid receiving side of the composite sheet and a second layer stacked below said first layer; said first layer being a non-woven fabric comprising thermoplastic synthetic resin fibers, said second layer being a non-woven fabric conspiring cellulose type fibers entangled with thermoplastic synthetic resin fibers; said first layer and said second layer being joined by fused bonds between the thermoplastic synthetic resin fibers of said first layer and the thermoplastic synthetic resin fibers of said second layer; and the absorbent composite sheet further comprising gaps between the thermoplastic synthetic resin fibers of said first layer for transferring a liquid from a top surface of said first layer to said second layer through said gaps; wherein said first layer has a fiber density in a range of 0.05 to 0.20 g/cm 3 when a pressure of 4.9 kPa is applied thereto, said second layer has a fiber density in a range of 0.015 to 0.10 g/cm 3 when a pressure of 4.9 kPa is applied thereto, and the fiber density of said first layer is higher than that of said second layer; said liquid blocking back sheet is disposed below said second layer; and said second layer defines a primary absorbent body of said absorbent article and the first layer is non-coextensive with said second layer and has a portion that extends outwardly beyond a periphery of said second layer and is bonded to the back sheet.
