Abstract
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.
