“…The positive effect of water on the dyeing process was caused by the enhancement of solubility of reactive dyes in the scCO 2 ( Figure 50). Gao et al 108 applied a series of reactive dyes containing halogenated acetamide reactive group, (Figure 51) to cotton fabric in scCO 2 without pre-treatment or co-solvents. They studied the new dyes in scCO 2 with a dye concentration of 0.5% o.w.f., system temperature ranges from 353 to 393 K, dyeing time of 1-3 h, at a constant pressure of 20 MPa.…”

This review highlights the great role of supercritical carbon dioxide fluid technology in textile dyeing processes. The unequivocal physical characteristics of supercritical carbon dioxide are presented and further researched to continue the development of high efficiency, compact dyeing to save energy and water in manufacturing processes. This review also focuses on the solubility of the dyes in scCO2 as well as the application of the technology to both synthetic and natural fabrics. Some factors relating to the economics of sustainable scCO2 technology are also outlined.

“…Coloration efficiency is generally quantified by means of the K / S and the fixation efficiency ( F ) 57,63‐70 . Two K / S values are generally evaluated: the first one on the “just‐dyed” samples, the second after treating the textiles with an appropriate high temperature solvent extraction to remove the unfixed dye.…”

Supercritical fluid dyeing is a promising technology that was first proposed in the 1980s to overcome the high energy demand and water consumption of conventional textile coloration. This review covers its advances from 2014 to the present, from the successful industrial implementation of supercritical fluid dyeing of polyethylene terephthalate to the most recent results obtained for the dyeing of other synthetic and natural textiles. Specific attention is also dedicated to the most innovative applications of supercritical fluid dyeing such as the functionalisation of textile and non-textile substrates, which may give rise to the development of other sustainable processes or novel advanced materials in the near future.

“…2). A series of reactive disperse dyes incorporating the halogenated acetamide group were recently synthesized by Gao et al [21] for dyeing cotton fabric in scCO 2 . The results showed that the color strength of dyed cotton fabric increased favorably with increasing temperature and time, and found that color fastness to washing and rubbing were also reasonably good.…”

Textiles production processes such as sizing, scouring, bleaching, mercerizing, dyeing, printing, and finishing are characterized by a huge consumption of water, energy, and chemicals. The toxic effluent discharge generated in these processes mainly contains by-products, residual dyes, salts, acids and alkalis, auxiliary chemicals, and other solvents. Their discharge into neighboring water bodies is posing a serious threat to the flora and fauna. At present, however, development in the textile and clothing industry has focused on the use of some green technologies as alternatives to conventional wet processes to promote sustainable production and consumption of textiles and clothing. In recent years, emphasis has been put on developing cleaner, cost-effective, and value-added textile products for a variety of applications without compromising the issues related to health and the environment. This chapter is intended to provide a summary of recent developments in the coloration and finishing of textile fibers and to provide details of the ecofriendly strategies developed to reduce the waste generation in the textiles and clothing sector. Finally, their implications in the sustainability of clothing products are also outlined.
