The present invention relates to scrap leather re use which is fully based on sustainable and the process of enhancing leather wastage and scrap into beautiful leather product. More particularly, the present invention relates to converting leather scrap into leather sheet with the help of glue. Further, the present invention effectively saves wastage of leather and save environment from the pollution.

Further, the present invention effectively saves wastage of leather and save environment from the pollution.

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.

The present invention relates to leather fibers for product materials, physically extracted from cowhide, and more specifically, the leather fibers are easily obtained for each length so that there is an advantage in that the leather fibers having different lengths can be respectively used as materials more appropriately for various articles such as leather sheets or yarns.

A method for the treatment of flexible laminar covers is described. One aspect includes selecting a low-quality material with a visible surface. A first layer of a first resin in a liquid state with a weight of a first predetermined value is deposited on the first surface. The resin is dried by applying a heat source to obtain an intermediate laminar semi-finished product, A second layer of a second resin in a liquid state with a weight of a second predetermined value is deposited on an active surface of a laminar support. The resin is dried by applying a heat source. The laminar support is coupled with the laminar semi-finished product so as to face the active surface to obtain a coupled sandwich. The sandwich is calendered by applying predetermined pressure and temperature. The sandwich is heated to a predetermined temperature so as to obtain a laminar finished product.
