▎ 摘　　要

NOVELTY - Graphene-based foam light and thin fabric is a double-layer structure comprising surface weft, surface warp, inner weft, inner warp, wiring and filling line. The surface weft is silk fiber. The inner weft is cotton fiber. The surface warp and inner warp are polymer fiber. The wiring is polylactic acid fiber. The filling line is graphene foam-modified polymer fiber. USE - Graphene-based foam light and thin fabric used for warming bed (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-based foam light and thin fabric comprising immersing polymer fiber in graphene oxide solution, oscillating, taking out, drying, spraying with hydrazine hydrate, sealing, heating and reacting, taking out, cooling to room temperature, obtaining graphene foam-modified polymer fiber, taking graphene foam-modified polymer fiber and polylactic acid fiber as raw materials, pulling, drawing, twisting, obtaining graphene foam-modified polymer fiber polylactic acid fiber spun yarn, taking silk fiber as surface weft, polymer fiber as surface warp and inner warp, cotton fiber as inner weft, and graphene foam-modified polymer fiber polylactic acid fiber spun yarn, preparing into double-layer structure, machine weaving into fabric, dyeing, dehydrating, drying and finalizing the design to obtain the product.
