Plasma and Ultrasonic Process in Dyeing of Wool Fibers with Madder in Presence of Lecithin

The environmental safe treatment methods were used to improve the penetrability of wool fibers with natural dye (Madder) in the presence of chemical and physical modified natural soybean lecithin. The dyeing conditions of wool fiber with madder were optimized by response surface methodology (RSM). The five independent variables were selected at low and high level values. The ANOVA results of the quadratic model show that the model terms such as dyeing temperature, dyeing time, lecithin concentration, plasma treatment duration, dyeing method, and their interactions are significant. Moreover, the optimum conditions which were proposed for the natural dyeing of LTP-treated wool fibers cause dyeing temperature reach to 76.53 degrees C in the presence of acetylated lecithin.
