Title (EN) SURFACE SHEET FOR ABSORBENT ARTICLE
(FR) FEUILLE DE SURFACE EXTERNE POUR ARTICLE ABSORBANT.
(JA) 吸収性物品用の表面シート
Abstract:
(EN) This surface sheet (1) for absorbent article comprises a first fiber layer (11) and a second fiber layer (12). The surface sheet (1) is used in such a manner that the first fiber layer (11) is positioned toward a wearer's skin contact surface side. The first fiber layer (11) further comprises high convex parts (1b) and low convex parts (1s) which protrude from the second fiber layer(12)-side toward the first fiber layer(11)-side. The interior parts of the high convex parts (1b) and the low convex parts (1s) are filled with a fiber which configures the first fiber layer (11). With the high convex parts (1b) seen in cross-section view in a thickness direction Z, the hydrophilicity of high convex part apex parts (1bu) on an apex part(1bt)-side in the first fiber layer (11) is greater than the hydrophilicity of high convex part bottom parts (1bd) on the second fiber layer(12)-side in the first fiber layer (11), and the hydrophilicity of the second fiber layer (12) is greater than the hydrophilicity of the high convex part apex parts (1bu).
(FR) Cette feuille de surface (1) pour article absorbant comprend une première couche de fibres (11) et une seconde couche de fibres (12). La feuille de surface (1) est utilisée de manière à ce que la première couche de fibre (11) soit positionnée vers le côté de la surface de contact avec la peau de l'utilisateur. La première couche de fibre (11) comprend, en outre, des parties convexes élevées (1b) et des parties convexes (1s) qui font saillie de la seconde couche de fibre (12)-côté vers la première couche de fibre (11)-côté. Les parties intérieures des parties fortement convexes (1b), et les parties faiblement convexes (1s) sont remplies d'une fibre qui forment la première couche de fibres (11). Avec les parties convexes élevées (1b) vues en coupe transversale dans le sens de l'épaisseur Z, le caractère hydrophile des sommets de la partie convexe élevée (1bu) sur sommets (1bt)-dans la première couche de fibres (11) est supérieure au caractère hydrophile des parties inférieures de parties convexes élevées (1bd) sur la seconde couche de fibres (12)-dans la première couche de fibres (11), et le caractère hydrophile de la seconde couche de fibre (12) est supérieur au caractère hydrophile des parties de sommet de la partie convexe élevée (1bu).
(JA) 本発明の吸収性物品用の表面シート(1)は、第1繊維層(11)と第2繊維層(12)とを有する。表面シート(1)は第1繊維層(11)が着用者の肌当接面側に位置するように使用する。第1繊維層(11)は、第2繊維層(12)側から第1繊維層(11)側に向けて突出した高凸部(1b)と低凸部(1s)とを有し、高凸部(1b)及び低凸部(1s)は内部が第1繊維層(11)を構成する繊維で満たされている。高凸部(1b)を厚み方向Zに断面視した際、第1繊維層(11)における頂部(1bt)側の高凸部頂部(1bu)の親水度が、第1繊維層(11)における第2繊維層(12)側の高凸部底部(1bd)の親水度よりも高く、第2繊維層(12)の親水度が、高凸部頂部(1bu)の親水度よりも高い。
