dc.description.abstract	Wool and silk fibres have been effectively dyed with an aqueous extract of C. sinensis from an acidic dye bath (pH * 4.0). Methanol extract of the dye has been used for measuring different kinetic and thermodynamic parameters. The results indicate that the dye has an affinity for wool and silk. The standard affinity value of C. sinensis for wool fibre is greater than that for the silk fibre and it increases with the increase in temperature. Rate of dyeing for wool is lower as compared to that of silk. Studies on adsorption isotherm indicate that this dye is adsorbed on protein fibres chiefly following Langmuir adsorption mechanism	en_US
