When a dye is used, the dye concentration is 0.3 to 10% by weight, and when a surfactant is used, it is 0.5 to 5% by weight. The first ultraviolet absorber treatment step can be performed at 80 to 95 ° C. for about 30 to 120 minutes by immersing the fiber product in the treatment agent. Since the treatment agent is usually used in an aqueous system, when the first ultraviolet absorber having low solubility in water is used, it is treated with a ball mill using a surfactant to obtain a dispersion of the first ultraviolet absorber. be able to. The pH of the treatment agent is generally 3 to 8.5, but when a benzophenone-based UV absorber is used as the first UV absorber, the benzophenone-based UV absorber dissolves when the pH is 7 or higher. Uniform adhesion of UV absorber is possible.
(2) Fix (FIX) treatment Textile products after dyeing are usually subjected to a fix treatment before the softener treatment. In the fix treatment, the dyed fiber product is usually immersed in a fix treatment liquid containing a fix treatment agent such as a tannic acid compound, an aromatic sulfonic acid condensate, a polyvalent phenol derivative, and the like at 60 to 80 ° C.

In order to improve flexibility, it is preferable to use an amino-modified silicone oil in combination with the finish treatment agent as a dispersibility improver for the second ultraviolet absorber. The density | concentration of the 2nd ultraviolet absorber in a finishing agent is 1 to 10 weight%. The finishing treatment step can be performed for about 10 to 30 minutes at 20 to 50 ° C. by immersing the fiber product in the finishing agent. Since the finishing treatment step is usually carried out in an aqueous system, when a second ultraviolet absorber having low solubility in water is used, the second ultraviolet absorber can be emulsified with stirring in combination with a surfactant.
