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.
Claims17
A process for preparing a reconstituted leather product comprising the steps of
- a) blending leather fibers with bonding fibers and resin to form an essentially dry homogenous dispersion, wherein leather fibers are at least 50% of the total amount of fibers blended by weight and the bonding fibers are at least 20% by weight of the total fiber amount;
- b) forming the blended mixture into a formed mat;
- and
- c) curing the resin in the formed mat to produce a reconstituted leather product by an essentially dry process where 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.
