| Résumé : |
Levelness in dyeing is assessed traditionally in leather industry by subjective visual method or grading using a grey scale. In the present investigation, an attempt has been made to develop a reliable objective method for the assessment of levelness based on instrumental techniques. Three methods based on Mean Delta ECIE (color difference based on method of Commission International de I'Eclairage), Mean Delta ECMC (color difference based on method of Color Measurement Committee of the Society of Dyers and Colorists, U.K) and Relative Unlevelness Index (RUI) were screened for use on leather substrate and compared with the visual assessment method. The study was carried out for 13 shades on goat upper leathers. Results show that the method based on Mean Delta ECMC is the most suitable for all the shades and has a good correlation with the visual assessment rating. |
