The invention discloses a graphene blanket which comprises a heat insulation layer, a heat preservation layer, a main heating layer, a heat diffusion film layer and a skin-friendly layer, wherein the heat insulation layer, the heat preservation layer, the main heating layer, the heat diffusion film layer and the skin-friendly layer are sequentially bonded from outside to inside; the main heating layer is used for providing heat energy, and is formed by alternately weaving warps formed by graphene yarns and bamboo fiber yarns and wefts formed by the graphene yarns and bamboo charcoal yarns in a mutually perpendicular mode; the warp yarns are formed by single yarn doubling of graphene yarns and bamboo fiber yarns, and the weft yarns are formed by single yarn doubling of graphene yarns and bamboo charcoal yarns; one end of the main heating layer is fixedly connected with a heating electrode, and the heating electrode is electrically connected with a controller for supplying power to the heating electrode; the controller comprises a storage battery unit for storing electric energy and a second charging interface for directly supplying power to the heating electrode. The invention provides a soft and comfortable graphene blanket with good moisture absorption and moisture conduction. |
