Title (EN) WATER ABSORBENT SHEET
(FR) FEUILLE ABSORBANT L'EAU
(JA) 吸水性シート
Abstract:
(EN) This water absorbent sheet (1) comprises a base material sheet (2) and a water absorbent polymer. The water absorbent polymer is a thermoplastic water absorbent polymer, or a water absorbent polymer that dissolves in a solvent. Looking at the water absorbent sheet (1) in planar view, polymer arrangement areas (3), where the water absorbent polymer is arranged, and polymer non-arrangement areas (4), where the water absorbent polymer is not arranged, are arranged dispersed in the planar direction. Looking at the water absorbent sheet (1) in cross-sectional view, the polymer arrangement areas (3) are arranged in a center region spaced away from both surfaces of the base material sheet (2).
(FR) La présente invention a trait à une feuille absorbant l'eau (1) comprenant une feuille de matériau de base (2) et un polymère absorbant l'eau. Le polymère absorbant l'eau est un polymère thermoplastique absorbant l'eau, ou un polymère absorbant l'eau qui se dissout dans un solvant. En regardant la feuille d'absorption d'eau (1) en vue plane, des zones d'agencement de polymère (3), où le polymère absorbant l'eau est disposé, et des zones de non-agencement de polymère (4), où le polymère absorbant l'eau n'est pas disposé, sont disposées en dispersion dans la direction plane. En regardant la feuille absorbant l'eau (1) en vue en coupe transversale, les zones d'agencement de polymère (3) sont agencées dans une région centrale espacée des deux surfaces de la feuille de matériau de base (2).
(JA) 本発明の吸水性シート(1)は、基材シート(2)と吸水性ポリマーとを有する。吸水性ポリマーは、熱可塑性吸水性高分子、又は溶剤に溶解する吸水性高分子である。吸水性シート(1)を平面視して、吸水性ポリマーが配されたポリマー配置部(3)と吸水性ポリマーが配されていないポリマー非配置部(4)とが面方向に分散して配されている。吸水性シート(1)を断面視して、ポリマー配置部(3)が、基材シート(2)の両面それぞれから間隔を空けた中間領域に配されている。
