▎ 摘  要

NOVELTY - Preparing of heating fabric containing graphene and spider silk comprises (i) joining 5-15 pts. wt. graphene in 30-40 pts. wt. bentonite improved solution, adding hydrochloric acid, adjusting pH value to 5.5-6.5, reacting at 55-75°C for 35-45 minutes under rotating speed of reaction is 550-750 revolutions/minutes, washing, and drying to obtain functional graphene improved material; (ii) mixing the functional graphene improving material and polyester chips according to the weight ratio of 1:5, melting, and extruding at 170-180°C to obtain polyester chip improving material; (iii) melt-spinning the polyester chip improvement material to obtain polyester chip improvement function graphene spinning, which is the first warp; and (iii) taking spider silk modified heating fiber blended yarn as the second weft yarn; and (iv) interlacing first warp yarn and the second weft yarn and overlapping in the warp and weft directions. USE - Preparation method of heating surface material containing graphene and spider silk. ADVANTAGE - The method enables to prepare heating surface material that has excellent heat preservation and heating effect, and enhanced heat preservation time of the product.
