A method for producing an antimicrobial cellulose fiber. The method includes reacting a reactive compound with an antimicrobial agent to prepare a reactive antimicrobial compound, chemically fixing the reactive antimicrobial compound to a cellulose fiber through chemical bonding between the reactive compound and the cellulose fiber, and stabilizing the cellulose fiber structure. Further disclosed is an antimicrobial cellulose fiber produced by the method. The antimicrobial cellulose fiber is a human friendly material that has excellent antimicrobial activity and deodorizing performance. The antimicrobial cellulose fiber can be manufactured in the form of raw cotton, sliver, roving yarn, spun yarn, woven fabric, knitted fabric, non-woven fabric, etc. The antimicrobial cellulose fiber may be blended with other fibers, such as natural fibers and synthetic fibers.
