Fireproof and heat-insulating multilayer composite fabric for firefighter wear and preparation method of fireproof and heat-insulating multilayer composite fabric

The invention discloses a fireproof and heat-insulating multi-layer composite fabric for firefighter clothing and a preparation method thereof. The fireproof and heat-insulating multi-layer composite fabric is prepared by quilting a fireproof layer, a waterproof breathable layer, a heat-insulating layer and a comfortable layer, the fireproof layer is an aramid fiber woven fabric; the waterproof breathable layer comprises aramid fiber non-woven fabric and a PTFE (Polytetrafluoroethylene) film; the thermal insulation layer comprises aramid fiber non-woven fabric and a coating, and the coating contains thermal insulation aerogel and polyurethane emulsion; the comfortable layer comprises an aramid fiber non-woven fabric and an aramid fiber blended base fabric. Through weaving and non-weaving of various aramid fibers and compounding and quilting of multiple layers of aramid fabric, the aramid fiber non-woven fabric is modified by utilizing heat-insulating aerogel, and the heat-insulating aerogel inhibits flowing o
