Add time:08/07/2019    Source:sciencedirect.com

The effect of benzotriazole type UV-absorbers Tinuvin P and Tinuvin 327 and 2,4-dihydroxy benzophenone in the dyeing of polyester fabrics with C.I. Disperse Yellow 86 and C.I. Disperse Red 86 at various depths of dyeing was studied. Various amounts and two application processes of the UV-absorber were used. The dye and UV-absorber uptake, and the light and sublimation fastness of the fabrics dyed and those treated with the UV-absorber were determined and the results compared with those obtained with the corresponding samples dyed in absence of a UV-absorber.
