Abstract:
(EN) The purpose of the present invention is to provide ligand-immobilized sea-island composite fiber wherein both generation of microparticles caused by detachment of sea components from island components and generation of microparticles because of the destruction of fragile sea components are suppressed. The present invention is a sea-island composite fiber formed from sea components and island components, wherein: the value (L/S) of the average total length (L) of the perimeter of all island components in a cross-sectional surface perpendicular to the axis of the fiber divided by the average cross-sectional surface area (S) for the cross-sectional surface is 1.0 – 50.0 µm-1; the distance to the outermost island component from the surface is 1.9 µm or less; and compounds containing amino groups form covalent bonds with the polymer constituting the island components at an electron charge density of 0.1 to less than 500 µmol per 1 g dry weight.
(FR) La présente invention vise à obtenir une fibre composite mer-île à ligand immobilisé permettant d'obtenir la suppression de la formation de microparticules provoquée par le détachement des constituants mer des constituants île et de la formation de microparticules provoquée par la destruction des constituants mer fragiles. À cet effet, la présente invention concerne une fibre composite mer-île constituée de constituants mer et de constituants île. La valeur (L/S) de la longueur totale moyenne (L) du périmètre de tous les constituants île dans une surface de section transversale perpendiculaire à l'axe de la fibre divisée par la surface de section transversale moyenne (S) de la surface en coupe transversale est de 1,0 à 50,0 µm-1 ; la distance jusqu'au constituant île le plus à l'extérieur à partir de la surface est inférieure ou égale à 1,9 µm ; et des composés contenant des groupes amino forment des liaisons covalentes avec le polymère constituant les constituants île à une densité de charge d'électrons comprise entre 0,1 et moins de 500 µmoles pour 1 g de poids sec.
(JA) 本発明は、島成分からの海成分の剥離による微粒子発生及び脆弱な海成分の破壊による微粒子発生が共に抑制されたリガンド固定化海島複合繊維を提供することを目的としている。本発明は、海成分と島成分とからなる海島複合繊維であって、繊維軸に対し垂直な断面の全島成分周長の平均合計長(L)を該断面の平均断面積(S)で除した値(L/S)が1.0~50.0μm-1であり、表面から最外島成分までの距離が1.9μm以下であり、乾燥重量1g当たり0.1μmol以上500μmol未満の電荷密度で上記海成分を構成するポリマーにアミノ基含有化合物が共有結合している海島複合繊維を提供する。
