Abstract
(EN)
[Problem] To provide a material which is for improving the gloss of hair and body hair of an animal and is made of a fibrous structure. [Solution] This material for improving hair gloss employs a fibrous structure that comprises a synthetic fiber to which an amino acid derivative is ionically bonded. The fibrous structure, to which an amino acid derivative is ionically bonded, gradually releases the amino acid derivative from the fibrous structure. By bringing the fibrous structure into contact with hair, the amino acid derivative transfers to the hair, and the absorption of internal scattered light by the hair is enhanced, thereby improving hair gloss. Thus, when an animal wears such a fibrous structure, that is, a fibrous structure processed into a garment shape, hair gloss can be naturally improved. The present invention can be mainly applied to mammals including humans.

La présente invention vise à fournir une matière qui est destiné à améliorer le brillant des cheveux et des poils d'un animal, et qui est constitué d'une structure fibreuse. À cet effet, l'invention concerne un matériau pour améliorer le brillant des cheveux/poils, qui utilise une structure fibreuse qui comprend une fibre synthétique à laquelle un dérivé d'acide aminé est ioniquement lié. La structure fibreuse, à laquelle un dérivé d'acide aminé est ioniquement lié, libère progressivement le dérivé d'acide aminé de la structure fibreuse. En amenant la structure fibreuse en contact avec les cheveux/poils, le dérivé d'acide aminé se transfère sur les cheveux/poils, et l'absorption de lumière diffusée interne par les cheveux/poils est améliorée, améliorant ainsi le brillant des cheveux/poils. Ainsi, lorsqu'un animal porte une telle structure fibreuse, c'est-à-dire une structure fibreuse transformée en forme de vêtement, le brillant des cheveux/poils peut être naturellement amélioré. La présente invention peut être principalement appliquée à des mammifères, y compris des êtres humains.

【課題】 繊維構造物からなる動物の毛髪及び体毛の毛づや改善材を提供することを目的とする。 【解決手段】アミノ酸誘導体がイオン結合された合成繊維を含む繊維構造物を毛づや改善材とする。アミノ酸誘導体がイオン結合された繊維構造物は、繊維構造物からアミノ酸誘導体を徐々に放出する。当該繊維構造物を毛に接触させておくことで、アミノ酸誘導体が毛に移行し、毛の内部散乱光の吸収を強化することにより毛づやが改善される。よってかかる繊維構造物、すなわち衣服形状に加工した繊維構造物を動物に着用させれば、自然な毛づやの改善が可能となる。本発明は主としてヒトを含む哺乳動物に適用できる。
