Abstract
An absorbent article such as a diaper has an outer layer of a porous fabric and an inner absorbent core. A separator layer of thermally bonded nonwoven fabric is positioned between the outer layer and the core to minimize rewet by liquids. The fibers of the nonwoven fabric of the separator layer have a diameter greater than 28 microns, and at least 5 crimps per extended inch, and the fabric has a porosity of about 90-95%, to provide superior rewet properties.
