It is an object of the present invention to provide a polyester based artificial hair which has an excellent spinning processability, maintains fiber properties such as heat resistance, strength and elongation and the like, and has excellent curl holding properties and iron setting properties. A flame retardant polyester based artificial hair which has an excellent spinning processability, maintains fiber properties such as heat resistance, strength and elongation and the like, and has excellent curl holding properties and iron setting properties can be obtained by melt spinning a composition obtained by melt kneading a polyester, a phosphorus containing flame retardant and/or a bromine containing flame retardant and at least one compound selected from the group consisting of a carbodiimide compound, a bisoxazoline compound and an isocyanate compound.
A flame retardant polyester based artificial hair, formed from a composition having intrinsic viscosity of 0.5 to 1.4 which is obtained by melt kneading 100 parts by weight of (A) a polyester made of one or more of polyalkylene terephthalate or a copolymer polyester comprising polyalkylene terephthalate as a main component, 5 to 30 parts by weight of (B) a phosphorus containing flame retardant and/or a bromine containing flame retardant and 0.05 to 10 parts by weight of (C) at least one compound selected from the group consisting of a carbodiimide compound, a bisoxazoline compound and an isocyanate compound.
