The present invention relates to a method for making a leather laminate having a textured surface, and leather laminates made by this method. The laminates comprise a leather layer bonded to a reinforcing fabric with an adhesive, the reinforcing fabric providing strength to the laminate. The method involves dry milling the laminate in humid air, during which the reinforcing fabric constrains the laminate causing the textured surface to form.

A method for producing a recycled leather fabric according to an embodiment of the present invention may comprise steps of: processing cowhide pieces or waste to produce cotton-like leather fiber; preparing a mixture by mixing the cotton-like leather fiber with cotton-like fiber; producing a leather thread by spinning the mixture; weaving the leather thread to produce a fabric; crushing and beating cowhide to produce cowhide short fibers; laminating the cowhide short fibers onto the fabric; and entangling the laminated cowhide short fibers with the leather thread by pressing the cowhide short fibers into the fabric.

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 of making stretch leather composites is provided. The method includes providing a semi-finished leather. The semi-finished leather is split to obtain a final split having a thickness of from 0.10 mm to about 1.25. The final split is dried to obtain a crust. The crust is laminated with a stretch fabric impregnated with a stiffener, e.g., starch, to prepare a laminate. The starch is removed from the stretch fabric after preparing the laminate, for example, by dissolving the starch in a liquid solution naturally present in another laminate processing step liquid. Laminating the crust can include the use of an adhesive. A method of manufacturing an article of footwear can include providing a stretch leather composite, cutting the stretch leather composite to conform to a predetermined shape, and manufacturing the footwear using the stretch leather composite.
