The effect of wool fibre hydrophobicity on anthraquinonic dye sorption into wool and on physical properties of dyed wool fibres was evaluated in this research. Dyeing experiments were performed on wool fabric samples, untreated and pretreated with a chloroform and methanol mixture. Newly synthesized Blue and Green anthraquinonic dyes and commercially available C. I. Acid Blue 80 dye were used for wool fabric dyeings. Wool samples were dyed in aqueous solutions of dyes as well as in dye and surfactant solutions at 60 °C and 90 °C temperatures. The data of dyeing experiments have shown that dye sorption into wool fibre mostly depends on the dye structure. The physical properties of dyed wool fibres varied depending on removal of hydrophobic outer layer of wool fibre as well as surfactants used in dyeing solutions.
