Thermodynamic characteristics of cotton dyeing with reactive dyes in non-aqueous media

Understanding the dyeing behaviors of reactive dyes onto cotton in non-aqueous media is helpful to facilitate development sustainable dyeing. Here, thermodynamic characteristics with liquid paraffin (LP) and decamethylcyclopentasiloxane (D5), were investigated compared those aqueous medium. The results showed that adsorption isotherms LP, D5, water accorded Freundlich model, indicating proceeded via physical multi-molecular layers. Furthermore, enthalpy entropy using LP D5 positive, which was significantly different from an These properties help understand interpret behavior media.
