(57) [Summary] [Purpose] A fiber having fiber properties sufficient for processing and containing various kinds of metal fine particles, and having various functions such as antibacterial, deodorant, and conductive properties of the metal fine particles. Provided are a fine metal particle-containing fiber having excellent expression ability and a method for producing the same. [Constitution] A metal fine particle-containing fiber, characterized in that the fine metal particle is contained in a fiber having a polar group capable of ion exchange or ion coordination and having a crosslinked structure. In addition, after the metal ion is ion-exchanged or ion-coordinated to the polar group in the crosslinked fiber containing the polar group capable of ion exchange or ion coordination, the reduction reaction is immediately performed to precipitate the metal fine particles in the crosslinked fiber. A method for producing a fiber containing fine metal particles. [Effect] Since the metal fine particles are uniformly contained in the fiber at a high concentration, various functions of the metal fine particles, antibacterial properties, Provided are fibers having deodorant properties, conductivity, etc., and processed products of the fibers. |
