▎ 摘  要

NOVELTY - A graphene thermostatic fabric (1) comprises fibrous tissue (10) having 1st tissue surface (101), 2nd tissue surface (102), and interspace (103) between 1st tissue surface and 2nd tissue surface; and graphene thermostatic layer (20) adhering to 1st tissue surface and filling a portion of the interspace, comprising hydrophobic resin (201) and nano-graphene sheets (202) dispersed in the hydrophobic resin. Thermal conductivity of graphene thermostatic layer varies with a change of an ambient temperature, and thermal conductivity of graphene thermostatic layer perpendicular to 1st tissue surface is less than thermal conductivity of graphene thermostatic layer parallel to 1st tissue surface. USE - A graphene thermostatic fabric for clothes material. ADVANTAGE - When the ambient temperature is higher, the graphene thermostatic layer can accelerate heat dissipation from human skin to achieve the cooling effect; when the ambient temperature is lower, the graphene thermostatic layer can homogenize temperatures of different portions of the human skin, absorb infrared from the human skin, and then emit the far infrared to the human skin, to achieve the warming and thermostatic effects at the same time. In comparison with the current technologies of functional fibers, the graphene thermostatic fabric has excellent adhesion and wash fastness; and the method of manufacturing the graphene thermostatic fabric does not affect the fiber yield and efficiency of the drawing and weaving processes and effectively reduces manufacturing cost. Additionally, due to the excellent conductivity of the graphene, the graphene thermostatic fabric has an antistatic property, when a conductive material is further added to graphene thermostatic layer to act as a conductive line of a physiological sensor arranged on the functional clothes, design flexibility of the functional clothes can be effectively increased, and manufacturing cost of the functional clothes can be greatly reduced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene thermostatic fabric which involves mixing 1st solvent and 2nd solvent to form mixed solvent, where boiling point of 1st solvent is not greater than 80 degrees C, boiling point of 2nd solvent is not less than 120 degrees C, and surface tension of 2nd solvent is 30-60 mJ/m2; adding nano-graphene sheets to mixed solvent; dispersing nano-graphene sheets with mechanical force to form suspension solution of nano-graphene sheets; adding hydrophobic resin to nano-graphene sheets suspension solution; dispersing nano-graphene sheets and hydrophobic resin with mechanical force to form graphene resin solution; and coating or printing graphene resin solution on surface of fabric, removing mixed solvent in graphene resin solution, to form graphene thermostatic layer adhering to surface of fabric. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional diagram of a graphene thermostatic fabric.
