摘要
A resin composition and a flameproofing method are desired which are necessary for flame-retardant dope-dyed polyester fibers which are excellent in light resistance and durability and can have any of various colors. Provided is a flame-retardant fiber obtained by melt-spinning a flame-retardant polyester resin composition comprising: a flame retardant comprising at least one inorganic phosphorus-nitrogen compound selected from a group consisting of ammonium polyphosphate, melamine polyphosphate, and phosphazene compounds; a colorant; and a thermoplastic polyester resin. The fiber is characterized in that the contents of the inorganic phosphorus-nitrogen compound, the colorant, and the thermoplastic polyester resin are 0.1-12 mass%, 0.01-5 mass%, and 83-99.89 mass%, respectively, of the total amount of the polyester resin composition.
