NOVELTY - The utility model claims a heat-insulating fibre cotton comprises fibre cotton main body, the fibre in the cotton main body comprises fibre cotton body, a metal coating, fibre monofil, low temperature heat insulation material, the graphene layer and corrosion resistant layer, the metal skin on top of the fibre monofilament, the fibre monofilament is in low temperature heat insulation material, the low temperature heat-insulating material on the graphene layer, the graphene layer on the corrosion layer, the surface of said metal envelope provided with a heat-conducting groove. This utility model through the fibre cotton body, a metal coating, a heat conducting groove, fibre monofil, closing a vacuum ball, low-temperature heat-insulating material layer and graphene layer are matched with each other, the fibre cotton has the function of thermal insulation, so that the fibre cotton when better use effect and avoids the problem that the fibre cotton is used, because the non-insulating fibre cotton, resulting fibre cotton used in some places, fibre cotton use effect is not good condition occurs.
