▎ 摘　　要

NOVELTY - Fire-proof and heat-insulating multi-layer composite fabric, comprises a fire-proof layer, a waterproof ventilating layer, a heat insulating layer, and a comfortable cotton layer, which are respectively arranged from an outer layer to an inner layer. The fire-proof layer is far-infrared ceramic fiber, and aramid fiber. The waterproof ventilating layer is polyisophthaloyl metaphenylene diamine (aramid fiber 1313), poly-p-phenyleneterephthamide (aramid fiber 1414), Japan high moisture permeability water pressure resistant film, and Teflon (Polytetrafluroethylene) activation film. The heat insulating layer is graphene knitted cloth, superfine glass wool fiber and the coating on superfine glass wool fiber. The coating comprises a heat insulation gas gel and a polyurethane emulsion. The comfortable cotton layer is aramid fiber and polyester-cotton blended fiber. USE - The fire-proof and heat-insulating multi-layer composite fabric is useful for fire protection. ADVANTAGE - The fabric has excellent heat protection and flame retardant performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing fire-proof and heat-insulating multi-layer composite fabric, comprising (a) grinding the nano-far-infrared ceramic fiber with water to form a slurry, adding magnesium oxide and sodium silicate, stirring and mixing uniformly, and placing into an ultrasonic processing tank, vibrating for 6-12 hours, drying and grinding for 2-4 hours, and adding 1-butyl-3-methylimidium acetate to obtain a spinning raw liquid, spinning and discharging to obtain a fire-proof layer fabric, (b) mixing aramid 1313, aramid 1414, and Japan's high moisture permeability and water pressure resistant film, carding into strips and mixing in strip, and spinning to obtain fabrics, setting Teflon(Polytetrafluroethylene) activation film on this layer of fabric to prepare waterproof ventilating layer fabric, (c) placing 3-8 pts. wt. fluorite, 7-12 pts. wt. borax, 45-55 pts. wt. quartz sand, 2-4 pts. wt. dolomite, 30-40 pts. wt. broken glass, and 2-4 pts. wt. soda ash into the centrifugal fiber forming machine to obtain superfine glass wool fiber, and spinning to produce ultra-fine glass wool fiber cloth, applying the heat-insulating gas gel and polyurethane emulsion under the ultrafine glass wool cloth, and combining with graphene cloth, to obtain the heat insulating layer, and (d) configuring sodium hydroxide solution, using sodium hydroxide solution to carry out alkali treatment on polyester fiber, washing alkali-treated polyester fiber with water, and acetic acid in sequence and drying to obtain the polyester fiber, and spinning to obtain the comfortable cotton layer fabric.
