Abstract
(EN)
An aspect of the present invention is a fiber for artificial hair which is made of a polyvinyl chloride resin composition. When measured for dynamic viscoelasticity under the conditions shown below, this fiber for artificial hair has a loss tangent tanδ value X1 at 70°C of 0.06 to 0.12, and has a peak within the temperature range of 90°C to 110°C. (Conditions for measurement of dynamic viscoelasticity) A bundle of 40 fibers for artificial hair is measured at a heating rate of 4°C/min and a frequency of 1 Hz.

Un aspect de la présente invention est une fibre pour cheveux artificiels qui est constituée d'une composition de résine de polychlorure de vinyle. Lorsqu'elle est mesurée pour une viscoélasticité dynamique dans les conditions présentées ci-dessous, cette fibre pour cheveux artificiels a une valeur tanδ de tangente de perte X1 à 70 °C de 0,06 à 0,12, et a un pic dans la plage de température de 90 °C à 110 °C. (conditions de mesure de viscoélasticité dynamique) Un faisceau de 40 fibres pour cheveux artificiels est mesuré à une vitesse de chauffage de 4 °C/min et une fréquence de 1 Hz.
