| Abstract: | The dyeing kinetics and thermodynamics for PLA fibre dyed with the natural dye curcumin have been studied. The rate of dye uptake, half dyeing time, diffusion coefficient, standard affinity, heat and entropy of dyeing have been determined. Linear isotherms are obtained, suggesting that the mechanism of dyeing is similar to that of disperse dyes. The rate of dye uptake and the total dye uptake increase with the increase in dyeing temperature. |
