 Full text | Abstract: The binding behaviour of 1.4-diamine anthraquinone derivative disulphonic CI Acid Blue 80 dye with nonionic surfactants based on ethoxylated alkylamines and fatty alcohols or alkylphenol (NPE) in aqueous solutions was investigated by means of conductivity measurements as well as by absorption spectroscopy. When the concentration of the surfactants was lower than the critical micellar concentration and the dye/surfactant molar ratio was ca. 1:1, the interaction of the dye with ethoxylated fatty alcohols or NPE was significantand dependent on temperature. It was established that the extent of interaction between the dye and surfactant is in correlation with the results of dye exhaustion from a dyebath as well as the colour strength of dyed wool fibre. |
