Adsorption kinetics and thermodynamic study of Cuminum cyminum L. dyeing on silk

• Dyeing of silk fabric with dye extracted from Cuminum cyminum L.
• Physicochemical parameters of dyeing of silk fabric with cumin dye in terms of enthalpy, entropy changes and activation energy of adsorption were studied.
• Pseudo first-order and second-order kinetic models were used to examine the adsorption kinetic data.

Adsorption kinetic study of cumin dye on silk fabric was carried out under optimal dyeing parameters. The physicochemical parameters of dyeing of silk fabric with natural dye, extracted from Cuminum cyminum L. were examined in terms of enthalpy, entropy changes and activation energy of adsorption. Pseudo first-order and second-order kinetic models were used to examine the adsorption kinetic data.
