PURPOSE:To obtain the title fiber having excellent washing resistance, maintaining deodorizing and antimicrobial effects for a long period of time by holding a water-insoluble inorganic metallic compound in the interior of cellulosic, fiber. CONSTITUTION:Cellulosic fiber is impregnated with an aqueous solution of metallic salt such as copper, silver, zinc, titanium or zirconium, for example, by immersion method (or vat method), the metallic salt is permeated into the yarn, treated with an aqueous solution of an acidic or alkali metallic salt and the water-soluble metallic salt is converted into the water-insoluble salt to give cellulosic yarn maintaining deodorizing and antimicrobial effects for a long period of time and having excellent washing resistance. |
