| Résumé : |
Color-forming rules and mechanism of methylamine and protein fibers dyed by four iridoids, genipin, loganin aglycone, oleuropein aglycone and E-6-O-methoxycinnamoyl scandoside methyl ester aglycone were researched. The results showed that, before the formation of final pigments, intermediates were formed. A continuous color change following classical color matching principles was observed when the pigments formed by genipin and oleuropein aglycone reacted individually with methylamine were mixed. However, when genipin and oleuropein aglycone reacted simultaneously with methylamine, the situation was different. The results of single dyeing and combination dyeing of protein fibers showed that color of the dyed protein was the same as that formed by each iridoid with methylamine. This means that the structure of iridoid is the dominant factor for the color-forming process. The classical color-matching principle would be observed when two iridoids were applied to dye protein fibers separately. However, during simultaneous combination dyeing, the classical color-matching principle was not observed. |
