APPLICATIONS OF GREEN CHEMISTRY PRINCIPLES IN TEXTILE WET PROCESSING

Abstract

The conventional finishing and dyeing processes practiced in the textile industry have a huge impact on the environmentand human health. This impact is due to the use of toxic chemicals, huge amounts of water usage, discharge of theeffluents generated by the textile industry in the water bodies, inefficient treatment of the discharged, water,atmospheric emissions and high energy consumption. The aim of the present study is to discuss the applications of greenchemistry principles in eco-friendly textile wet-treatment processes. This paper discusses the use of enzymes(biochemical approach) and physical treatment processes like ultraviolet radiation, plasma, and ozone technology. In caseof dyeing it discusses the use of natural dyes and technologies like Air Dye, ultrasonic, microwave, plasma, supercriticalCO2, electrochemical and Nano-DyeTM.
