METHOD FOR MANUFACTURE OF COLOR-CHANGE LAMINATED SPLIT LEATHER USING THERMOCHROMIC MICROCAPSULE AND COLOR-CHANGE LAMINATED SPLIT LEATHER USING THE SAME

摘要

PURPOSE: A method for fabricating color change laminate leather using thermochromic microcapsules and the laminated leather fabricated thereby are provided to form a skin film layer on the surface of split leather, thereby showing creativity by color change according to temperature. CONSTITUTION: A method for fabricating color change laminate leather using thermochromic microcapsules comprises the steps of: mixing water dispersion thermochromic microcapsules and aqueous polyurethane resin (S1); coating release paper with the mixture and forming a skin film layer (S2); curing the skin film layer (S3); drying the skin film layer and coating with an aqueous polyurethane adhesive to form an adhesion layer (S4); laminating pretreated split leather on the adhesive layer (S5); drying the skin film layer and split leather (S6); maturing the skin film layer and split leather to enhance the strength (S7); and separating the release paper form the skin film layer (S8).
