A method for manufacturing a breathable hybrid leather includes: a raw material supply step of supplying the natural leather of recycled leather; a step of applying a hot-melt adhesive to the upper surface of the leather raw material; a bonding step of supplying a fabric to the upper surface of the adhesive layer and applying heat and pressure to the leather raw material, the adhesive layer, and the fabric to obtain a bonded fabric; and a step of ironing and coating the bonded fabric a plurality of times.

The invention relates to a method and the production of natural leathers from pieces of natural leather torn into different-sized fibers which are sorted and placed, once they have been mixed with a binder, in successive layers (6, 7 and 8) on a support sheet (9) provided with filaments crossing the different layers. The support sheet (9) and filaments (10) are extracted once the binder substance has cured.

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.

A method for making an upgraded and embossed laminar supporting element, in particular leather, by applying several layers on the surface of the leather, including an aqueous base coat and a lacquer coat and partially removing water and/or solvent from said layers followed by embossing and optionally further drying.

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 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.

The present disclosure concerns a module (100) for inline embossing of a leather product (1) comprising a leather support sheet (2) having a surface finish layer of one or more partially cured coating layers. The module comprises an application means (10) to apply a protective foil (4) onto the partially cured layer (3) to form a laminate (5). The module also comprises a pressure group (20) including an embossing roller (21) having an outer surface with a relief structure (22) so as to emboss a negative of the surface relief structure into the leather product, across the protective foil.
