The dyeing of cationized cotton fabric with 3-chloro-2-hydroxypropyltrimethyl ammonium chloride 69% (Quat 188) using Cochineal dye was studied using both conventional and ultrasonic techniques. Factors affecting dye extraction and dye bath exhaustion were investigated. The results indicated that the dye extraction by ultrasound at 300W was more effective at lower temperatures and times than conventional extraction. Also, the colour strength values obtained were found to be higher with ultrasound than with conventional techniques. However, the results showed that the fastness properties of the dyed fabrics with ultrasound are similar to those of the conventional dyed fabrics. The scanning electron microscope (SEM) and X-ray diffraction (XRD) were measured for cationized cotton fabrics dyed with both conventional and ultrasound techniques, thus showing the sonicator efficiency.
