“…It was also found that reusing the residual bath allowed us to obtain a depth of shade very similar to the first dyeing with further reduction of the cited environmental parameters [8].…”

“…Effect of the Dye Bath pH The effect of the dye bath pH on the dyeability of polyamide fabrics with the olive vegetable water was conducted at different pH (2)(3)(4)(5)(6)(7)(8). As shown in Figure 5, the color yield (K/S) of the dyed fabrics seemed to be inversely proportional with the pH of the dye bath.…”

“…Dyeing Procedures Polyamide fabric was dyed at different pH values (2)(3)(4)(5)(6)(7)(8), at different temperatures (50-100 o C), and for different durations (15-120 min). Throughout the manuscript, conventional heating is abbreviated to (CH) and ultrasonic treatment is abbreviated to (US).…”

“…Moreover, the phenolic compounds, which are very abundant in the olive vegetable water are characterized by their high affinity to wool and acrylic fabrics with good fastness properties [7,8]. This aqueous extract contains tannins and flavonoid compounds like apigenin, luteolin and quercetin [9,10].…”

The present study reports the valorization of the olive vegetable water in natural dyeing. HPLC analysis of the phenolic extract obtained from the used olive vegetable water showed that the predominant flavonoid compounds were luteolin and apigenin. Hydroxytyrosol and various phenolic acids were also identified. This abundant waste was used as a possible dye bath for dyeing polyamide fabrics in conventional and ultrasonic techniques. It was found that these synthetic fibers possess high affinity to the olive vegetable water giving brownish shades with generally good fastness properties. Factors affecting the dyeing performances such as pH, temperature, and duration of the dyeing time were studied. Ultrasonic dyeing showed marked improvement in the dye uptake compared to the conventional heating. The results also showed that the use of this method enhanced some fastness properties compared to the conventional method. Moreover, it was found that using ultrasonic technique can reduce the concentration of polyphenols so that it reduced the chemical oxygen demand COD and biological oxygen demand BOD 5 better than conventional heating method.

“…Bechtold et al [114] reported the use of anthocyanin dye extracted from grape pomace for the purpose of textile dyeing. Likewise, it has been shown that olive mill wastewater (OMW), which is a dark brown to black effluent produced during olive oil extraction, has the potential to be used as a natural dye for coloration of wool [115] and polyester fabrics [116]. The depth of shade and fastness properties were found to be very 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.
