▎ 摘　　要

NOVELTY - Electrothermal functional textile of graphene/tourmaline comprises an active heating fabric layer (1). The textile further comprises an electric heating reinforcing layer set on the active heating fabric layer, a heat storage layer set (3) on the electric heating reinforcing layer and a wearable protection layer (4) set on the heat storage layer. USE - Used as electrothermal functional textile of graphene/tourmaline. ADVANTAGE - The textile: can realize low-voltage driving of 4-12 V and a heating rate of 0.3-8.4℃/s through Joule heating in the active heating area and has high electrothermal conversion efficiency and good comfort. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing electrothermal textile of graphene/tourmaline comprising (a) preparing active heating fabric layer, processing the fabric electrode to the active heating fabric layer through conductive filament, then connecting the power supply with the fabric electrode, forming a conductive path, (b) grafting the mixed solution of the graphene and the tourmaline to the surface of the active heating fabric layer by pressure atomization to form an electric heating reinforcing layer, (c) using pressure atomization method to divide the graphene oxide for 3-5 times to process the electric heating reinforcing layer, to form a heat storage layer and (d) using the pressure atomization method to divide the aqueous polyurethane solution into 3-5 times to process the heat storage layer to form a wearable protective layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing the structure of the electrothermal functional textile of graphene/tourmaline. 1Active heating fabric layer 2Electric heating reinforcing layer 3Heat storage layer 4Wearable protective layer
