In order to achieve the dyeing and functional finishing of wool fabrics with anthocyanins from Lycium ruthenicum Murray which were extracted using 80%ethanol/water mixed solution and distilled water,respectively,and both extracts were characterized by Fourier transform infrared spectroscopy(FTIR).And then according to the dyeing kinetics and thermodynamics of wool fabrics dyed with anthocyanins from Lycium ruthenicum Murray extracts,dyeing mechanism was explored.The results indicate that the main chemical components in the extract of Lycium ruthenicum Murray were anthocyanins,and there were slight differences in the structure of anthocyanins extracted with different solvents.Through the study of adsorption thermodynamics and kinetics,it is found that the dyeing process of wool fabrics with anthocyanins follows Langmuir and Freundlich isothermal adsorption models and pseudo-second-order kinetic model.
