Abstract

The present invention relates to a polyester-based fiber for artificial hair obtained by melt spinning a polyester resin composition. The polyester resin composition includes 100 parts by weight of a polyester resin, 5 to 40 parts by weight of a brominated epoxy flame retardant, and 1.5 parts by weight or more and less than 7 parts by weight of an antimony oxide. The polyester resin is at least one kind of resin selected from the group consisting of polyalkylene terephthalate and a copolymerized polyester containing polyalkylene terephthalate as a main component. The polyester-based fiber for artificial hair has aggregates of the brominated epoxy flame retardant that are dispersed in the polyester resin in the form of islands, as viewed in the cross section of the fiber parallel to the fiber axis direction. The present invention also relates to hair ornament products including the polyester-based fiber for artificial hair and a method for producing the polyester-based fiber for artificial hair. Thus, the present invention provides a polyester-based fiber for artificial hair having a gloss and a texture that are similar to those of human hair, and hair ornament products including the polyester-based fiber for artificial hair.
