On peut atteindre ce but avec un cheveu artificiel à base de polyester qui est obtenu par le mélange du poly(téréphtalate d’éthylène) avec du poly(téréphtalate de triméthylène) dans un rapport spécifique et ensuite le filage à chaud du mélange obtenu. En utilisant en outre un agent ignifuge bromé, il devient possible d’obtenir un cheveu artificiel à base de polyester ayant un caractère ignifuge en plus des caractéristiques décrites précédemment.
