  • Publication number: 20210154642
    Abstract: An object of the present invention is to provide a ligand-immobilized sea-island composite fiber in which generation of fine particles due to peeling of a sea component from an island component and generation of fine particles due to destruction of a fragile sea component are both suppressed. The present invention provides a sea-island composite fiber comprising a sea component and island components, in which a value (L/S) obtained by dividing the average total length (L) of the perimeter of all island components in a cross section perpendicular to the fiber axis by the average cross-sectional area (S) of the cross section is from 1.0 to 50.0 ?m?1, a distance from the surface to the outermost island component is 1.9 ?m or less, and an amino group-containing compound is covalently bonded to a polymer constituting the sea component at a charge density of 0.1 ?mol or more and less than 500 ?mol per 1 gram dry weight.
