Flame-retardant fabric is a core functional workwear fabric with key flame-retardant properties: incombustible on contact with fire and self-extinguishing when the fire source is removed. It also offers practical benefits like wash and wear resistance, breathability and comfort, with its flame-retardant effect remaining unimpaired after repeated washing. Widely applied in high-risk working scenarios such as fire protection, power, metallurgy and chemical engineering, it builds a solid safety barrier for frontline workers.
