Investigation of adsorption isotherms used for wool dyeing by aqueous extraction of cehri fruit (Fructus Rhamni Petiolari) and dyeing of wool and silk accompanied by various mordants

Abstract

In this study, adsorption isotherms were obtained by processing wool with dyestuff solutions of different concentrations extracted from cehri fruit with water. These isotherms follow the Nernst equation; the Nernst constant was determined and interpreted. In addition, wool and silk fibres were dyed with the same dyestuff solution and various mordants. Colours having a high fastness which could be used on an industrial scale were produced.
