摘要： A laminated non-woven fabric comprising a laminated material of an intermediate layer of a melt-blown non-woven fabric obtained by melt-blowing an olefin-type resin, an inner and outer layers of a spun-bonded non-woven fabric which chiefly consists of polyester-type fibers and in which the fibers are bonded together locally and at a coarse density, wherein the fibers constituting the inner and outer layers are inserted in the melt-blown non-woven fabric and are intermingled with fibers in the melt-blown non-woven fabric or in the spun-bonded non-woven fabrics of the opposite sides, so that the layers are coupled together as a unitary structure, and a process for producing the same. In the laminated non-woven fabric, the melt-blown non-woven fabric and the spun-bonded non-woven fabrics are fastened and stuck together free of defects to exhibit softness, porosity, water resisting property and like properties possessed by the melt-blown non-woven fabric as well as strength, hand, touch and like properties possessed by the spun-bonded non-woven fabric to their maximum degrees.
