Abstract
The textile-processing industry is accountable for the significant use and contamination of freshwater resources. The textile industry needs to review and improve its current water consumption practices due to increased consumer knowledge of environmental regulations regarding freshwater contamination. One very interesting alternative that could help to create a more sustainable future is the foam-dyeing technique. This review paper examines the recent advancements in foam-dyeing technology, highlighting its benefits over traditional techniques, including lower energy and water consumption as well as less need for chemicals and dyes. The configuration of foam makes it possible to apply dyes more successfully, thus decreasing both the amount of dye used and the processing time. Additionally, compared to traditional processing technologies, foam-dyeing methods use less energy because they require a lower dyeing temperature. This study also emphasizes the current studies on foam dyeing on a variety of textile substrates, including cotton, polyester, and their blends, as well as on fibers, yarns, and fabrics. Additionally, a techno-economical comparison between conventional dyeing and foam dyeing is provided. This review paper additionally endorses Sustainable Development Goal 6 (clean water and sanitation) by examining the preservation of usable water and the decrease in wastewater discharge through foam-dyeing technology.
