Eco-Friendly Disperse Dyeingof Ultraviolet-Treated Polyester FabricUsing Disperse Yellow 211

Abstract

Dyes are widely used in the cosmetics, textile, leather, food, paper and plastic industries, but in view of toxicity, these dyes show carcinogenicity towards the environment in the form of effluents [1], due to which the dye bath needs modifications that not only reduce the effluent load but also make the textile processing ecofriendly. Modifications involve the use of modern techniques [2] such as ultraviolet radiation [3], plasma [4], gamma [5-6] ultrasonic, and microwave [7] -all of which make the dyeing process cost-, time-, and laboreffective as well as sustainable. Of these techniques, the role of UV radiation is gaining popularity due to its treatment and efficiency. Previously it has been reported that UV radiation adds value in coloration, as well as improving fastness properties. Due to such wonderful benefits, these rays are used in textiles, wood, fibre, and
