Abstract

La présente invention concerne une fibre de chlorure de polyvinyle pour des cheveux artificiels qui sont fréquemment transformés en postiches en enroulant la fibre autour d'un tube et en thermofixant la fibre pour la boucler, ou en plaçant la fibre entre des équipements chauffés pour la friser. Lorsque ce travail est réalisé à une température élevée de fixage ou d'équipement dans un élément de fabrication afin de faire en sorte que la fibre de chlorure de polyvinyle ait une forme résistante et moins déformable, la sensation au toucher du postiche obtenu change de façon problématique par rapport à la sensation d'origine pour devenir dure et indésirable. Durant l'extrusion par fusion d'une composition de résine de chlorure de vinyle qui contient un stabilisant thermique sélectionné parmi le groupe constitué de stabilisants thermiques à hydrotalcite et de stabilisants thermiques à Ca-Zn pour obtenir une fibre de chlorure de polyvinyle, selon l'invention, le pourcentage de retrait thermique à sec à 90 °C est réglé dans la plage de 15 à 35 % et la quantité de lubrifiant qui adhère à la fibre est réglée dans la plage de 0,01 à 0,1 % en poids. Il a été constaté le réglage ci-dessus a pour résultat une fibre qui peut être bien façonnée par thermofixage et qui peut fournir des postiches dépourvus de déformation ou de détérioration de la sensation au toucher.
