PROBLEM TO BE SOLVED: To maintain a fiber property such as heat resistance and strong elongation of a normal polyester fiber, excellent in flame retardancy, setability, combing property, and controlled the gloss of the fiber, and a polyester artificial hair fiber using the same Provide artificial hair. SOLUTION: A composition obtained by melt-kneading a polyester containing a phosphorus-containing flame retardant and / or a bromine-containing flame retardant and an additive comprising at least one of a compatibilizer, a lubricant and a bleed inhibitor, or polyester and phosphorus The above-mentioned problems have been solved by melt spinning a composition obtained by melt-kneading a copolymer obtained by copolymerizing a contained flame retardant and an additive comprising at least one of a compatibilizer, a lubricant and a bleed inhibitor. A flame-retardant polyester-based artificial hair fiber is obtained. [Selection figure] None |
