초록

The dyeing behavior of scaled wool by acid dyes, Methyl Orange, Ethyl Orange and Butyl Orange has been studied at 50, 60 and 70℃. The adsorption isotherms on descaled wool of these dyes were described in terms of the Langmuir-type adsorption formula at the equilibrium state. Also Klotz's equation could be applicable to dye-wool complexes. The first binding constant decreases with temperature and increases with increasing alkyl chain length. It was found that the free energy and the enthalpy changes are all negative and the entropy change is positive.
