Provided is a fiber structure which can be used as an adsorbent and the like. A fiber structure to be treated is subjected to the graft polymerization with a graft component that constitutes a graft chain, wherein the fiber structure to be treated is formed with a fiber assembly that contains at least a conjugated fiber and at least a part of the fiber surface of the conjugated fiber is composed of an ethylene-vinyl alcohol copolymer. The graft polymerization may be carried out by, for example, immersing the fiber structure to be treated in which an active species has been generated by the irradiation with a radioactive ray in a graft-component-containing solution that contains the graft component, thereby contacting the fiber structure to be treated with the graft component. By this method, the graft component can be polymerized at a high graft polymerization rate and a fiber structure having excellent adsorption performance and the like can be produced. |
