PURPOSE: To produce a composite nonwoven fabric excellent in mechanical characteristics such as tensile strength and interlaminar peeling strength, dimensional stability, flexibility, water absorption and moisture absorption, and suitable not only as a raw material for industrial materials but also as a raw material for general materials.
CONSTITUTION: This composite nonwoven fabric is produced by laminating nonwoven web layers B comprising regenerated cellulose staple fibers to both the surfaces of a synthetic filament nonwoven web layer A. The fibers of the nonwoven web layer A are partially heat-pressed therebetween. The fibers of the nonwoven web layer A and the fibers of the nonwoven web layer B are three-dimensionally interlaced with each other, and the fibers of the nonwoven web layer B themselves are also three-dimensionally interlaced with each other. Thus, the wholly incorporated composite nonwoven fabric is produced.
