Abstract
The photodegradation behavior of some azo and anthraquinone disperse dyes was investigated in solution in the presence of polyester and compared with that on polyester fiber. Ethyl acetate as a solvent, a soluble polyester of low molecular weight as typical model of polyester fiber, and monochromatic light of various wavelengths as light source were employed in the investigation. The influence of added polyester, dissolved oxygen, and of an ultraviolet absorber on the photodegradation of the dyes was studied to gain an insight into the nature of the photofading of the dyes on polyester fiber. It was found that the results obtained in polyester-containing solution correlated very well to those on polyester fiber.
