PROBLEM TO BE SOLVED: To provide a method for producing textile products in which the amount of caffeine immobilized on the textile products can be increased and the resistance of the caffeine immobilized on the textile products against washing is increased and the caffeine is gradually released into human bodies. SOLUTION: The textile product is obtained by treating a textile product with tannic acid and caffeine. In order to stably immobilizing the caffeine on the textile product, a complex of caffeine and tannic acid is formed on the textile product by treating the product with an aqueous tannic acid solution and is followed by treatment with an aqueous caffeine solution. Or, caffeine and tannic acid is mixed to form their complex in the solution mixture and a textile product is treated with the aqueous solution containing the complex. Or, after dyeing a textile product, the textile product is subjected to fixing treatment with tannic acid, then treated with tannic acid and treated with an aqueous caffeine solution. Further in another case, after dyeing a textile product, the textile product is subjected to fixing treatment with tannic acid and then treated with an aqueous caffeine solution.
