A method is provided for producing breathable leather material including the following steps: a leather-based material is provided; the leather-based material is perforated; a support body is provided; a finishing is applied to the support body such that a later visible side of the finishing is facing the support body and the finishing is transferred to the surface of the perforated leather-based material and removed from the support body.

A method of preparing recycling leather sheets comprise: pre-processing where leather wastes are neutralized and fatliquoring agents are adhered; separating leather fibers from the leather wastes that has undergone the pre-processing; mixing the separated leather fibers with fibers for improving a tensile strength of the separated leather fibers; and forming sheets by combining the mixed leather fibers and raw fabrics for floor. The method of preparing recycling leather sheets in the present invention may reduce environmental pollution by preparing recycling leather sheets through physical combination without using adhesives.

A method for molding or replicating leather samples for inspection, selecting and later using those samples in applications such as automobile interiors with leather surfaces that are laminated or have a loose grain appearance. In one process variant, the main steps include choosing original samples for replication, the original samples including a characteristic to be replicated; making a replication tool from the approved samples; and producing replicated molded samples with the replication tool that emulate the original samples, thereby enabling the replicated molded samples to be compared with the original sample.

A multi-layered material that includes a layer of natural leather or collagen leather with holes and/or micro-holes and coated with a hydrophobic agent, which is superimposed and adhered, by means of hydrolysis-resistant adhesives, said adhesives being arranged in a non-laminar fashion, to a layer of waterproof, breathable material to prevent the passage of water and to allow the passage of air therethrough.

A method for manufacturing hybrid-natural leather having excellent appearance quality and good durability such as light resistance, water resistance, elongation and abrasion resistance is provided. Particularly, the fiber layer having a similar structure to the natural leather is introduced to the natural leather and the natural leather and the fiber layer are bonded and fused with each other under a specific condition to manufacture hybrid-natural leather having excellent durability while preventing wrinkles, stretching, and the like from being generated.
