Abstract: A flame retardant, heat-insulated and moisture permeable coated fabric and its manufacturing method comprises the steps of: mixing the expandable graphite with the chemical containing phosphorus or nitrogen; mixing the mixture of the expandable graphite and the chemical containing phosphorus or nitrogen in the foam material to form the to-be-coated material; one-side or two-sides coating the to-be-coated material on the surface of the textile cloth by using wet coating to form at least one flame retardant, heat-insulated and moisture permeable coating which can permeate the textile cloth on the surface of the textile cloth. Thereby, the flame retardant, heat-insulated and moisture permeable coating can absorb heat and expand to form the porous structure, which not only can absorb heat and smoke simultaneously, but also can wrap the textile cloth to avoid the phenomena of secondary combustion and melting drip.
