Abstract

L’invention concerne une composition de résine pour former des cheveux artificiels à base de polyester conservant les propriétés des fibres de polyester ordinaires comme la résistance thermique, la résistance à l’allongement, tout en convenant parfaitement à la pose et la centrifugation, avec un retard de flamme important. La composition de résine pour cheveux artificiels à base de polyester retardateur de flamme comprend un polyester et, incorporés dans celui-ci dans des proportions spécifiques, un retardateur de flamme à base de composé de brome et un composé d’antimoine, et présente un indice d’oxygène limiteur (LOI) supérieur ou égal à 26, et une viscosité intrinsèque (IV) de 0,5 à 1,0. La centrifugation par fusion de la composition de résine permet d’obtenir des cheveux artificiels à base de polyester retardateur de flamme conservant les propriétés des fibres de polyester ordinaires comme la résistance thermique, la résistance à l’allongement, tout en convenant parfaitement à la pose et la centrifugation.
