Abstract
Various non-aqueous media were employed to examine the adsorption and solubility properties of disperse dyes on poly(ethylene terephthalate). The dye adsorptions in alkane media were much higher than those in other non-aqueous systems. The adsorption of disperse dyes on poly(ethylene terephthalate) increased with decreasing number of carbon atoms of alkane groups. In the case of relationships between dye adsorption and dye solubility in various non-aqueous media, the adsorption of the dye is linearly and inversely proportional to the dye solubility in the logarithmic plot. The adsorption dependency on the solubility of dyes was shown to have a similar pattern for different disperse dyes.
