Title (EN) NON-WOVEN FABRIC FOR SEMIPERMEABLE MEMBRANE SUPPORT
(FR) TISSU NON-TISSÉ POUR SUPPORT DE MEMBRANE SEMI-PERMÉABLE
(JA) 半透膜支持体用不織布
Abstract:
(EN) The purpose of the present invention is to provide a non-woven fabric for a semipermeable membrane support, which can provide good adhesion of a semipermeable membrane to a support, can make the thickness of the semipermeable membrane uniform and does not undergo the penetration of a coating solution through the non-woven fabric. The non-woven fabric for a semipermeable membrane support according to the present invention is a non-woven fabric mainly composed of organic synthetic fibers and has a semipermeable membrane supported on one surface thereof, wherein each of a coating surface of the non-woven fabric, which is a surface to be coated with the semipermeable membrane, and a non-coating surface of the non-woven fabric, which is a surface opposed to the coating surface, has a Bekk smoothness degree of 5 seconds or more and the internal bond strength of the non-woven fabric falls within the range from 0.4 to 0.8 N·m as measured in the sheet lateral direction.
(FR) La présente invention concerne un tissu non-tissé pour un support de membrane semi-perméable, qui peut fournir une bonne adhésion d'une membrane semi-perméable à un support, qui peut rendre uniforme l'épaisseur de la membrane semi-perméable et qui ne subit pas la pénétration d'une solution de revêtement à travers le tissu non-tissé. Le tissu non-tissé pour un support de membrane semi-perméable selon la présente invention est un tissu non-tissé principalement composé de fibres synthétiques organiques et présente une membrane semi-perméable portée sur une de ses surfaces, chacune d'une surface de revêtement du tissu non-tissé, qui est une surface à revêtir par la membrane semi-perméable, et d'une surface de non revêtement du tissu non-tissé, qui est une surface opposée à la surface de revêtement, possède un degré de lissé Bekk de 5 secondes ou plus et la résistance interne du tissu non-tissé tombe dans la plage allant de 0,4 à 0,8 N·m telle que mesurée dans la direction latérale de la feuille.
(JA)  本発明の課題は、半透膜の支持体への密着性が良好でかつ半透膜の厚さ均一性が良好で、なおかつ塗工液の裏抜けがない半透膜支持体用不織布を提供することである。 本発明に係る半透膜支持体用不織布は、有機合成繊維を主体とする不織布であり、該不織布の一方の面に半透膜を支持することとなる半透膜支持体用不織布において、 不織布の半透膜を塗工することとなる塗工面及び該塗工面とは反対面となる非塗工面のいずれもが、ベック平滑度が5秒以上であり、かつ、不織布のシート横方向の内部結合強さが0.4~0.8N・mの範囲内である。
