This invention is concerned with a process for producing deodorizing cellulose fibers on which a considerable amount of copper hydroxide and/or zinc hydroxide is fixed highly strongly, which process is characterized in that cellulose fibers are allowed to contact with a colloidal solution of copper hydroxide and/or zinc hydroxide prepared by adding an alkaline substance to an aqueous solution of a water-soluble copper compound and/or a water-soluble zinc compound. Deodorizing fibers so obtained are capable of effectively removing malodorous gaseous substances, such as hydrogen sulfide, ammonia, methyl mercaptan, etc., and exhibit excellent deodorizing effects. In addition, the deodorizing fibers, although they can be an excellent deodorizing material as they are, are excellent in workability and hence can be used in the form of a shaped product, including, e.g., granules, sheets, etc. They can therefore be applied to various used in the field of deodorization.
