Ultrasonic Dyeing of Polyester Fabric with Azo Disperse Dyes Clubbed with Pyridonones and Its UV Protection Performance

The textile sector is closely linked to environmental pollution as a result of the use toxic chemicals and their disposal in liquid waste, which negatively affects for environment. Moreover, industries, especially wet processing, consume large amount energy, water, chemical auxiliaries. Therefore, there an urgent need find solution that takes problem into account. Considering ultrasound environmentally safe alternative dyeing polyester fabrics with disperse dyes we have prepared before, comparison between ultrasonic method conventional at low temperatures was investigated. Dye exhaustion on fastness properties such washing, rubbing, light, perspiration all dyed were performed by two methods. Additionally, ultraviolet protection factors (UPF) evaluated.
