POLYESTER FIBER HAVING IMPROVED WEATHER RESISTANCE

摘要

PROBLEM TO BE SOLVED: To obtain polyester dyed things excellent in weather resistance for a long period of time by dyeing a polyester fiber material, after a mixture of specific benzophenone ultraviolet absorbers is added to the dye bath. SOLUTION: Benzophenone ultraviolet absorbers A and B of formulas I and II are added to the dye bath for polyester fiber fabric at a ratio A/B of 1/9-9/1 so that they may be applied to the fabric by 0.001-10 pts.wt. to increase the weather resistance of the dyed fabric.
