Abstract: A composite nonwoven fabric (1, 51, 61) and a process (100, 101, 102) for the production of the composite nonwoven fabric (1, 51, 61) are shown, wherein the composite nonwoven fabric (1, 51, 61) comprises at least one spunbonded nonwoven (8, 54, 64), which exhibits essentially continuous regenerated cellulosic filaments (4, 55, 65) deposited in a random orientation, and at least one layer (52, 62) of biobased biodegradable short fibers (14, 53, 63). So as to provide a fully biodegradable composite nonwoven fabric of the initially mentioned type, which exhibits a high stability and tensile strength as well as good absorption properties and haptic properties and, in addition, can be produced in a cost-efficient way, it is suggested that the composite nonwoven fabric (1, 51, 61) has at least one mixing area (56, 66) in which the filaments (4, 55, 65) of the spunbonded nonwoven (8, 54, 64) and the short fibers (14, 53, 63) are present in a state of physical interconnection.
