ABSTRACT:
A two-ply nonwoven fabric laminate comprises a first-ply of synthetic fibrous nonwoven material having an outer surface, an inner surface, and a thickness, and having a basis weight of from about 10 g/m.sup.2 to about 50 g/m.sup.2 ; and a second ply of fibrous nonwoven material having an outer surface, an inner surface, and a thickness, and having a basis weight of from about 10 g/m.sup.2 to about 50 g/m.sup.2. The inner surfaces of the first and second plies are adhered at their interface by a flexible, soft latex binder. The binder is adhered to substantially all fibers exposed on the inner surfaces of the first and second plies. The binder is present in the first ply from its inner surface to a depth of from about 20% to about 80% of its thickness, and is present in the second ply from its inner surface to a depth of from about 20% to about 80% of its thickness.
