摘要：

The adsorption kinetics of the UV-absorber Tinuvin P, 2-(2-hydroxy-5-methyl-phenyl)-2H-benzotriazole on polyester (PET) fabrics have been studied. Polyester fabrics were dyed with CI Disperse Blue 85 and a new red monoazo disperse dye in different depths (0.5, 1 and 2% o.w.f.) by application of the UV-absorber by different processes (pretreatment, simultaneous addition and aftertreatment) and various UV-absorber/dye molar ratios (0.5-3.5). The application of the UV-absorber (0.1-2.5% o.w.f.) resulted in a slight decrease in dye uptake by the pretreatment and simultaneous addition processes, and in most cases in an improvement of light fastness (0-2 units of the Blue Standard scale) of the dyed fabrics. The light fastness improvement was generally higher for the after treatment process and for the blue dye.
