摘要

The textile industry’s dyeing process consumes significant water and utilities, leading to environmental concerns due to wastewater disposal. Traditional dyeing methods often result in water pollution, making sustainability a pressing issue. To address this, researchers are developing eco-friendly alternatives. This chapter explores sustainable dyeing techniques, including foam dyeing, supercritical carbon dioxide (scCO2) dyeing, air dyeing, plasma-assisted dyeing, and laser-assisted dyeing. It provides an overview of conventional dyeing methods, highlighting their environmental impact, and examines innovative waterless dyeing solutions, discussing their principles, benefits, and limitations.
