Abstract
Fine metallic particles-containing fibers with various fine metallic particles therein, which have fiber properties to such degree that they can be processed and worked, and which can exhibit various functions of the fine metallic particles, such as antibacterial deodorizing and electroconductive properties are provided, as well as a method for producing the same.

Fine metallic particles-containing fibers, having ion-exchangeable or ion-coordinable polar groups, having crosslinked structure, and containing throughout fine particles of a substantially insoluble metal and a substantially insoluble metallic salt.
A method for producing fine metallic particles-containing fibers, comprising applying metal ions to crosslinked fibers having ion-exchangeable or ion-coordinable polar groups to thereby make the substantially insoluble metal ions ion-exchanged or ion-coordinated with the polar groups, followed by immediately reducing the fibers to thereby make fine metal particles precipitated in the crosslinked fibers.
A method for producing fine metallic particles-containing fibers, comprising applying metal ions or ions bonding to metal ions to precipitate substantially insoluble metallic salts to crosslinked fibers having ion-exchangeable or ion-coordinable polar groups to thereby make the ions ion-exchanged or ion-coordinated with the polar groups, then adding a compound capable of precipitating a substantially insoluble metallic salt to the fibers to thereby make fine particles of a substantially insoluble metallic salt precipitated in the crosslinked fibers.
