 This work compares the coloristic and colorfastness properties of organic cotton fabrics dyed using microwave irradiation and conventional dyeing methods with ramnospatialaris bois, quercosithaburansis decaine, and quercosithaburansis decaine plus ramnospatialaris bois. The dyed fabrics were analyzed by different analytical and technical methods, including RPHP-LCPAD, CIE lab spectrophotometer, SEMEDX, and colorfastness tests. The results show that microwave irradiation is a more efficient and cost-effective method for dyeing organic cotton fabrics compared to conventional dyeing methods, with almost the same color yields obtained in both processes.
