A breathable water resistant film provided by the present disclosure includes a base cloth and a nanofiber layer disposed on the base cloth, wherein the nanofiber layer is formed by an electrospinning solution including a first additive and a second additive. The first additive includes a nylon copolymer and an alcohol, and the second additive includes a polysilazane resin and a perfluoropolyether-modified polysilazane resin.

A dry method for manufacturing a non-woven fabric from tanned leather scraps involves providing tanned leather scraps in the form of compact material, subjecting the tanned leather scraps to opening to tear the compact material into fiber, and subjecting the torn material to carding. Textile fibers are added during carding to obtain a web of mixed fibers, the textile fibers including wool fibers. The dry method further involves subjecting the web of mixed fibers to needling to obtain a felt. The web of mixed fibers is free of impregnating agents and includes a leather fiber component composed of tanned leather fibers having a diameter of between 4 ?m and 70 ?m and a length of between 4 mm and 20 mm. The leather fiber component is comprised in a weight percentage greater than or equal to 50% of a total weight of the fibers in the web of mixed fibers.

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.
