Energy conservation plays a vital role in overcoming the burning issues of global warming worldwide. The synthesis of organic dyes using the conventional method consumes high levels of energy, temperature, as well as solvents, which further leads to additional costs as well as increases in energy consumption. To save energy, time and cost, the synthesis of dye using microwave based energy might be a good option. In this study, a comparison was drawn between the conventional synthesis and microwave based synthesis of fluorescein dye. The resultant dyes were characterised using the different techniques of UV-Visible and FTIR spectroscopy. Furthermore, colour values were evaluated for dyed wool and Nylon 6 fabrics. In view of this, the work in the present investigation is related to the synthesis of fluorescein with two different methods (conventional and microwave). This dye may be used for various applications in the textile industry. [ABSTRACT FROM AUTHOR]
