PURPOSE:To obtain dyed material having excellent color fastness to light by subjecting polyester fiber to exhaustion dyeing with disperse dye and bringing into contact with aqueous solution containing ultraviolet absorber in high temperature range. CONSTITUTION:Polyester fiber is subjected to exhaustion dyeing with disperse dye by normal method and after said dyeing is almost finished (>=95% exhaustion), then brought into contact with an aqueous solution containing a known ultraviolet absorber at 100-150 deg.C to afford dyed material of polyester fiber having excellent color fastness to light. Said dyed material is suitable as a dyed material required of high color fastness to light such as seat for automobile. |
