Advanced Technology in Textile Dyeing

All over the world, dyeing is considered one of the significant parts of the textile colouration process. It refers to both the dyeing and printing process. Dyeing is the specific colouration of textiles, while printing is the localized application of colourants by a suitable method base on the design. The conventional aqueous dyeing process consumes a significant quantity of water, creating wastewater processing difficulties that arise global environmental threats and an alarming concern for sustainable development. This chapter discusses the scope, processing techniques, required machinery and equipment, advantages, and other aspects of the innovative and emerging sustainable, eco-friendly dyeing technologies. It will cover supercritical carbon dioxide dyeing, air dyeing, plasma-assisted dyeing, and laser-assisted dyeing. It is not limited to these but also discusses ultrasound-assisted dyeing, microwave-assisted dyeing, foam dyeing, enzymatic dyeing, reverse micelle dyeing, ozone-assisted dyeing, nano-bubble dyeing, and electro-chemical dyeing.
