PURPOSE: A seamless adhesion method is provided to simplify manufacturing process, production efficiency, etc for natural lather, thereby capable of manufacturing innovative natural leather products. CONSTITUTION: A seamless adhesion method comprises: a binder coating step(S1) spreading a thermosetting liquid polyurethane binder on a grain layer; and an adhesion step(S2) locating fabric for decoration on the grain layer, and seamlessly attaching the grain layer and the fabric. In the adhesion step, the grain layer and the fabric are attached by heating and pressing in temperature of 130-150 °C, the pressure 30-50 kg/cm^2 for 15-30 seconds, using hot press.
