Surface characterization of cotton and adsorption of fragrances by IGC

What is it about?

The surface characterizations of the WFK16000 standard cotton by dispersive, specific and total surface energy heterogeneity profiles with surface energy distributions and acid–base properties determined by surface energy analyser are presented in thiswork. The Dorris–Gray and Schultz methods for the determination of the dispersive surface energy component are compared, and their critical analysis is given. It is concluded that the Dorris–Gray method is more applicable at elevated temperature. Furthermore, Henry’s coefficient, standard free enthalpy, enthalpy and entropy data at infinite dilution and adsorption isotherms for some fragrances (benzyl acetate, Cyclal C, diphenyl oxide, eucalyptol, linalool and viridine) measured on dry cotton fibres by inverse gas chromatography at various temperatures are given. The temperature-dependent form of the Langmuir equation has been fitted to the multiple temperature adsorption isotherms with good agreement.
