PURPOSE: To obtain a fiber having deodorizing and antibacterial potencies and adequate washing durability by adding a metal ion elimination-preventing agent to an organic fiber having metal-containing carboxyl groups. CONSTITUTION: This production of a metal ion-containing organic fiber improved in durability is to graft polymerize methacrylic acid on an organic fiber such as a natural fiber e.g. cotton or wool, a synthetic fiber e.g. nylon or polyester, etc., for example, cotton yarns, treat the product with sodium hydroxide to change COOH into COONa, substitute Na with a metal ion such as copper, zinc, iron, nickel, cobalt or silver to obtain the cotton yarns having metal- containing carboxyl groups, then add a metal ion elimination-preventing agent comprising at least one compound selected from a group consisting of benzotriazole-based compounds, imine ring-containing compounds, triazine thiol compounds or silane coupling agents containing amino groups, mercapto groups or tertiary ammonium salts, e.g. 2,2-bishydroxymethylbutanol tris2[3(1- aziridinyl)]propionate. |
