【Abstract】 The fire-retardant cellulose fiber is spun by adding the certain P-N fire retartant to the carbamate solution. The properties of the fire-retardant cellulose fiber and the fire-retardant mechanism are studied by the technique of the Oxygen Index Measuring Instrument and Scanning Electrical Microscope （SEM）. The experimental results show that the appropriate fire-retardant cellulose fiber is obtained when the content of the fire retardant is up to 18⁰₀.更多还原
