CONJUGATED FIBER AND STRUCTURAL FIBER PRODUCT COMPRISING THE CONJUGATED FIBER

摘要

A structural fiber product usable as an adsorbent or the like is provided.;A graft component for forming a graft chain is graft-polymerized onto a structural fiber object; the structural fiber object comprises a fiber assembly comprising at least a conjugated fiber, and an ethylene-vinyl alcohol-series copolymer exists on at least part of a surface of the fiber. The graft polymerization may be conducted, for example, by exposing a structural fiber object to radiation to generate an active species and immersing the structural fiber object in a liquid containing a graft component to bring the structural fiber object into contact with the graft component. According to the method, the graft component can be polymerized at a high degree of grafting, and a structural fiber product having an excellent adsorption characteristic is obtained.
