In order to survey the possibility of an organic solvent as a dyeing medium, the dye uptake of C.I. Disperse Violet 1 on polyester fiber in 31 kinds of solvents including water was investigated. The dye uptake in alkanes was observed to be much higher than that in other organic solvents. As the number of carbon atoms in alkanes decreased, the dye uptake increased drastically. It was shown that dye uptake was linearly and inversely proportional to the solubility of the dye in various organic solvents in a logarithmic plot. It is very interesting that unless their flammable properties some alkanes are considered to be the excellent dyeing media for a non-aqueous dyeing system. Besides the practical aspects, the results obtained in this study may be beneficial in assisting the further development of non-aqueous dyeing systems.
