Composite nonwoven sheet material

A composite nonwoven sheet material includes pulp fibers, a reinforcement material and microfibers. The sheet material has one pulp-enriched first outer layer and one microfiber-enriched second outer layer, the reinforcement material is thereby interposed between the pulp-enriched first outer layer and the microfiber-enriched second outer layer and the pulp fibers and the microfibers penetrate the reinforcement material. Also disclosed is a process of producing such composite nonwoven sheet material and the use of such composite nonwoven sheet material.
