Abstract

La présente invention concerne un article absorbant pourvu d'un corps absorbant et d'un corps externe permettant de maintenir le corps absorbant. Le corps externe comprend l'une des structures (A) à (C) décrites ci-dessous, et la différence de transmittance de lumière totale dans la direction de l'épaisseur lors de l'absorption d'humidité par opposition à l'état sec est supérieure ou égale à 5 %. La couleur du corps externe selon le nuancier de Munsell satisfait l'un des points (a) à (c) indiqués ci-dessous. Structure (A) : structure pourvue d'une feuille de couche interne située du côté peau d'un utilisateur et comprenant des fibres thermoplastiques, une feuille de couche externe située du côté non peau et comprenant des fibres thermoplastiques, et une feuille contenant des fibres de cellulose disposée entre la feuille de couche interne et la feuille de couche externe. Structure (B) : structure pourvue d'une feuille de couche interne située du côté peau d'un utilisateur et comprenant des fibres thermoplastiques, une feuille de couche externe située du côté non peau et comprenant des fibres thermoplastiques, et une feuille contenant des fibres de cellulose disposée davantage vers le côté peau de l'utilisateur que la feuille de couche interne. Structure (C) : une structure pourvue d'une feuille de couche interne située du côté peau d'un utilisateur et comprenant une partie fibres thermoplastiques et une partie fibres de celluloses, et une feuille de couche externe située du côté non peau et comprenant des fibres thermoplastiques. (a) La clarté est de N 9,0 (blanc). (b) La teinte est R (rouge), YR (orange), ou Y (jaune), la clarté est de V8 ou moins, et la saturation est de C3 ou plus. (c) La teinte est GY (vert-jaune), G (vert), BG (cyan foncé), B (cyan), PB (bleu-pourpre), P (pourpre) ou RP (magenta foncé).
