ABSTRACT:
A reconstituted leather product and a method of manufacturing this reconstituted leather product is disclosed in which leather (preferably scrap leather) is ground or shredded into a fibrous state. The fibrous leather is mixed with a binder, such as natural rubber dissolved in an evaporatable solvent (e.g., naphtha), so as to form a paste-like mix. The mix is then extruded (or otherwise formed) into sheets or webs and is cured so as to drive off excess solvent. A reinforcing mesh web may be adhered to the back face of the sheet or may be sandwiched between layers of the fibrous leather and binder. The cured reconstituted leather may be finished to have any desired surface finish or color in a manner similar to real leather. The resulting reconstituted leather closely resembles real leather in feel, color, finish, odor, strength, flexibility, and appearance, but is of much lower cost.
