    摘要: A composite nonwoven sheet material comprising a reinforcement layer comprising mainly reinforcement filaments, a pulp layer comprising mainly pulp fibers, and a surface layer comprising mainly microfibers, wherein the pulp layer is interposed between the reinforcement layer and the surface layer, and wherein the pulp fibers are entangled with the reinforcement filaments and the microfibers. A process of producing a composite nonwoven sheet material, comprising: forming a fibrous web comprising a reinforcement layer comprising mainly reinforcement filaments, a pulp layer comprising mainly pulp fibers, and a surface layer comprising mainly microfibers, wherein the pulp layer is interposed between the reinforcement layer and the surface layer; and hydroentangling the fibrous web to form the composite nonwoven sheet material.
