Title (EN) ION EXCHANGE FIBER, WATER PURIFICATION FILTER AND WATER TREATMENT METHOD
(FR) FIBRE D'ÉCHANGE D'IONS, FILTRE DE PURIFICATION D'EAU ET PROCÉDÉ DE TRAITEMENT DE L'EAU
(JA) イオン交換繊維、浄水フィルタおよび水処理方法
Abstract:
(EN) The present invention relates to an ion exchange fiber which is provided with a core fiber and an ion exchange layer that is arranged around the core fiber and contains a crosslinked polymer compound having an ion exchange group, and which is characterized in that: the area of the ion exchange layer accounts for 50% to 90% (inclusive) of the total cross-sectional area of a cross-section that is perpendicular to the longitudinal direction of the ion exchange fiber; and the swelling ratio of the ion exchange fiber is 50% or less.
(FR) La présente invention concerne une fibre d'échange d'ions qui est pourvue d'une fibre à cœur et d'une couche d'échange d'ions qui est disposée autour de la fibre à cœur et contient un composé polymère réticulé ayant un groupe d'échange d'ions, et qui est caractérisé en ce que : la surface de la couche d'échange d'ions représente 50 % à 90 % (inclus) de la surface de section transversale totale d'une section transversale qui est perpendiculaire à la direction longitudinale de la fibre d'échange d'ions; et le taux de gonflement de la fibre d'échange d'ions est inférieur ou égal à 50 %.
(JA) 本発明は、芯繊維と、前記芯繊維の周囲に配置されるとともに、イオン交換基を有する架橋高分子化合物を含有するイオン交換層と、を備えるイオン交換繊維であって、前記イオン交換繊維の長手方向に垂直な断面において、前記イオン交換層の面積が全断面積の50%以上90%以下を占め、かつイオン交換繊維の膨潤率が50%以下であることを特徴とする、イオン交換繊維に関する。
