Provided is a fiber structure that can be used as an adsorbent or the like. A graft component constituting a graft chain is applied to a fiber structure to be treated which is formed of a fiber assembly in which at least a part of the fiber surface is formed of a fiber assembly including at least a composite fiber composed of an ethylene-vinyl alcohol copolymer. Graft polymerize. Graft polymerization may be performed, for example, by immersing a fiber structure to be treated in which active species are generated by radiation irradiation in a graft component-containing liquid containing a graft component, thereby bringing the graft component into contact with each other. By such a method, the graft component can be polymerized at a high graft polymerization rate, and a fiber structure excellent in adsorption performance and the like can be obtained. |
