Sustainable Eco‐Dyeing of Nylon 6 Using Papaver Rhoeas Flower Extract: Optimization and Application of Natural Dyes with Biomordants

Significant attention has been directed toward eco‐friendly practices in the textile industry to mitigate the extensive use of chemicals involved in production processes. This research explored the potential of Papaver rhoeas flowers as a sustainable dye source for the coloration of nylon 6 fabric. Precisely, the study aimed to optimize various dyeing variables to achieve the optimal coloration results for nylon 6 using the extract derived from red poppy flowers. The results suggested that the optimal conditions for achieving highest color strength were characterized by the pH of 3, the temperature of 100 °C, the dye concentration of 100% owf, the material‐to‐liquor ratio of 1:30, and the dyeing time of 60 min. In addition, the study evaluated the effectiveness of both metallic and biomordants in enhancing color strength, as well as wash and lightfastness properties. Among the biomordants tested, walnut husk at a concentration of 50% owf demonstrated the highest color strength. Further, it achieved light and wash fastness ratings of 5 and 8, respectively. These findings, thus, provide valuable insights into the utilization of Papaver rhoeas flowers as a sustainable dye source for nylon 6 fabric, thereby expanding its potential applications in textile dyeing processes.
