Abstract
Nine dyes having various functional groups were synthesized and applied on silk fabric. The equilibrium exhaustions %E of the dyes on silk were determined. From this the thermodynamic parameters such as partition coefficient K, and standard affinity, ??? which is a driving force behind the dyeing process are determined. There is a strong correlation between the %E and the thermodynamic parameters values on one hand and effect of aftertreatment on the thermodynamic parameters on the other hand. Keywords : exhaustion, aftertreatment, partition coefficient, standard affinities, thermodymanic parameters
