Abstract
A reconstituted leather product and process for making. The reconstituted leather product can be finished to have the look and feel of real leather and physical properties equivalent thereto. The process is essentially dry and involves reducing leather materials to fibers, preferably not longer than one inch. The process further involves blending these fibers with synthetic fibers, a resin and optionally other additives, forming the mixture into a mat, curing the mat and pressing the mat into a reconstituted leather product.
Claims12
A reconstituted leather product comprising:
- leather fibers in an amount of at least 50% by weight of the total fiber amount;
- bonding fibers in an amount of at least 20% by weight of the total fiber amount;
- and
- polymeric resin,
- wherein the reconstituted leather product at the end of the product's useful life is capable of being used as a starting material in the formation of the reconstituted leather product and the reconstituted leather product is produced by an essentially dry process.

A reconstituted leather product produced by the process of:
- blending leather fibers in an amount of at least 50% by weight of the total fiber amount with bonding fibers in an amount of at least 10% by weight of the total fiber amount, and resin to form an essentially dry homogeneous dispersion where said blending fibers melt when exposed to temperatures of between 325.degree. F. and 350.degree. F.,
- forming the blended mixture into a mat;
- and
- curing the resin in the formed mat to produce a reconstituted leather product wherein the product is produced by an essentially dry process.
