摘要:
A flame-retardant fabric may include a cellulosic fiber and a modacrylic fiber, the cellulosic fiber being a natural cellulose fiber containing a phosphorus compound, the modacrylic fiber containing an antimony compound, the flame-retardant fabric including the modacrylic fiber containing the antimony compound in an amount of 14 to 54 wt %, antimony in an amount of not less than 1.7 wt %, and phosphorus in an amount of 0.3 to 1.5 wt % with respect to the total weight of the flame-retardant fabric, and the flame-retardant fabric having a weight per unit area of not less than 160 g/m2. The flame-retardant fabric can be produced by subjecting a fabric including a natural cellulose fiber and a modacrylic fiber containing an antimony compound to flame-retardant treatment with a phosphorus compound.
