No full textA comparison of analytical methods for the quantificationof a reactive b-cyclodextrin fixed onto cotton yarns
No full textCotton yarns bobbins were treated in a water bath with different concentrations of a reactive b-cyclodextrin derivative. To quantify the amount of cyclodextrin fixed on the fiber different analytical methods were tested but none of them was reliable enough in the concentration range under investigation. Therefore, a new analytical method, fast and effective, was developed. From the measurement of cyclodextrin bath exhaustion, the amount of cyclodextrin chemically fixed and that physically adsorbed on the textile substrate was estimated. Two washing cycles were carried out to investigate the cyclodextrin washing fastnes
