After copolymerizing acrylic acid with acrylonitrile in an amount less than A fiber having a carboxyl group can be obtained by dissolving it to obtain a spinning stock solution and spinning this into a dilute aqueous solution of the above solvent. Alternatively, carboxyl groups can be introduced by treating commercially available acrylic fibers with hot water containing caustic soda and sodium chloride. In addition, when introducing a sulfonic acid group, use sodium methalylsulfonate, sodium allylsulfonate, etc. as a copolymerization component, or use sulfite, sodium sulfite, etc. as a reducing agent component in redox polymerization of acrylonitrile. Also, a sulfonic acid group can be introduced into the terminal group.

易に反応させることができる。The content of anionic functional groups contained in this fiber (hereinafter referred to as fiber A) is not particularly limited, but in order to be lightweight and exhibit a large deodorizing effect, 0.2 mmo P,
/g fiber or more is preferred. On the other hand, when the acrylonitrile content is less than 60%, fiber spinning performance decreases and fiber production becomes difficult. In order to react the fiber A with the transition metal compound, an alkali such as caustic soda,
The reaction can be easily carried out by neutralizing with ammonia or the like to convert the anionic functional group into a sodium salt or ammonium salt.
