Provided is an artificial hair made of a copolyester comprising polyethylene terephthalate copolymerized with an improving compound represented by <CHEM> in an amount of 1 to 8 mol%, which can be heatset for giving shapes such as curls or waves at a low temperature causing no migration or sublimation of disperse dyes, the shapes thus given being kept stably. Also provided is a process for producing such artificial hair, which can by employment of specific techniques keep the dry heat shrinkage at 170 DEG C of the obtained artificial hair below 10%. Then the resulting artificial hair exhibits good operatability of the heatsetting procedure. |
