Abstract: A process for recycling scrap of shoe stiffener comprising the steps of: 1. Kneading the collected scrap of shoe stiffener, having a core layer of TPU resin material (with filler) sandwiched in between two opposite net fabric layers, to be dense clumps; 2. Freezing the dense clumps to be hard frozen clumps; 3. Crushing the hard frozen clumps to be a crushed product including pellets of resin material, and short fibers; and 4. Extruding the crushed product including pellets and short fibers to produce a regenerated core layer; and covering or laminating two net fabric layers on opposite sides of the regenerated core layer to obtain a regenerated shoe stiffener sheet to enhance environmental protection and prevent from wasting of material resources.
