ANTIBACTERIAL FIBER AND RESIN AND PRODUCTION THEREOF.

摘要

This invention relates to: (1) antibacterial polyacrylonitrile or polyester fiber and resin containing 1 to 1,000 ppm, preferably 10 to 1,000 ppm, of silver in the form of silver sulfonate, (2) a method of producing the antibacterial polyacrylonitrile or polyester fiber or resin by reacting polyacrylonitrile or polyester fiber or resin having sulfo and/or sulfonate groups in its structure with a water-soluble silver compound in water, characterized in that said reaction is carried out at a temperature above the glass transition point of the polyacrylonitrile or polyester, (3) a method of producing the antibacterial polyacrylonitrile or polyester fiber or resin characterized by reacting polyacrylonitrile or polyester fiber or resin having sulfo and/or sulfonate groups in its structure with a water-soluble silver compound in water at a temperature above the glass transition point of the polyacrylonitrile or polyester and treating the reaction product with a reducing agent, and (4) antibacterial polyacrylonitrile or polyester fiber and resin produced by the above method (2) or (3).
