Method for producing antimicrobial cellulose fiber, fiber produced by the method and fabric using the fiber

A method for producing an antimicrobial cellulose fiber, the method comprising:

• reacting an antimicrobial agent with at least one reactive compound selected from the group consisting of triazine compounds, pyrimidine compounds, quinoxaline compounds, vinyl sulfone compounds, epoxy compounds, urethane compounds and acrylamide compounds to prepare a reactive antimicrobial compound;
• chemically fixing the reactive antimicrobial compound to a cellulose fiber to generate an antimicrobial cellulose fiber structure through chemical bonding between the reactive antimicrobial compound and the cellulose fiber such that the reactive antimicrobial compound is contained in an amount of 0.1 to 10.0% by weight with respect to the weight of the cellulose, wherein said chemically fixing comprises dipping the cellulose fiber in an aqueous solution of (i) 10 to 100 g/l of the reactive antimicrobial compound, (ii) 5 to 50 g/l of sodium carbonate and (iii) 20 to 200 g/l of sodium sulfate in a liquid ratio of 1:5-50 at 40 to 90° C. for 10 to 100 minutes to form chemical bonds;
• and
• stabilizing the antimicrobial cellulose fiber structure by reacting the antimicrobial cellulose fiber structure with an aqueous solution of 0.5 to 5.0% by weight of a plurality of metal compounds comprising two or more of sodium hydroxide, potassium hydroxide, calcium hydroxide, sodium carbonate, silver nitrate, zinc sulfate, zinc chloride, tin chloride, calcium chloride and copper sulfate at 10 to 90° C. until the content of the metal compound reaches 0.05 to 5.00% by weight with respect to the weight of the cellulose fiber.
