“…In recent years, with the improvement in people's living standards, the awareness of environmental protection, healthy and ecological habits have gradually become popular, and people pay more and more attention to human health. The potential unsafe factors of many chemical synthetic dyes and textile finishing agents have aroused widespread concern [1][2][3]. In the context of the global advocacy of green sustainable development, more and more researchers are committed to replacing synthetic chemicals with green resources without affecting the quality and efficiency of production.…”

Most traditional synthetic dyes and functional reagents used in silk fabrics are not biodegradable and lack green environmental protection. Natural dyes have attracted more and more attention because of their coloring, functionalization effects, and environmental benefits. In this study, natural dyes were extracted from lac and used for coloring and functionalization in silk fabrics without any other harmful dyes. The extraction conditions were studied and analyzed by the univariate method. The optimal extraction process was that the volume ratio of ethanol to water was 60:40 with a solid–liquid ratio of 1:10, and reacting under the neutrality condition for 1 h at 70 °C. Silk fabric can be dyed dark owing to the certain lifting property of lac. After being dyed by Al3+ post-medium, the levels of the washing fastness, light fastness, and friction fastness of silk fabric are all above four with excellent fastness. The results show that the dyed silk fabrics have good UV protection, antioxidation, and antibacterial properties. The UV protection coefficient UPF is 42.68, the antioxidant property is 98.57%, and the antibacterial property can reach more than 80%. Therefore, the dyeing and functionalization of silk fabrics by utilizing naturally lac dyes show broad prospects in terms of the application of green sustainable dyeing and functionalization.

“…Natural colorants are gaining popularity due to their nontoxic and environmentally beneficial properties. ,− There are numerous sources of color that may be extracted from plants, animals, and insects, and these sources can be used in a variety of ways to dye textiles. ,− Comparing the cost of production, getting dyes from waste and byproducts would be better than harvesting directly. ,,− However, there are drawbacks and difficulties in using natural colorants for dyeing textiles. ,− These include their inherent shortcomings, which have limited their potential for industrial use, , the lower yield and color fastness, mordant and other chemical requirements, and little to no attraction toward the textile substrate. − Also, using metallic mordants in the dyeing process increases the effluent burden because they do not exhaust in a residual dye bath. ,, …”

A very promising green chemistry concept that should gain more traction is the introduction of semiprepared azo dyes, which are made by modifying natural extracts with the azo group. This would reduce the dependency on toxic and nonbiodegradable synthetic dyes while also giving economic value to agricultural wastes. In the current study, an extract of peanut red skin was used as an agro-waste and a source of polyphenols to prepare azo dye by coupling it with a diazonium salt of ρnitroaniline. Then, the prepared dye was used to dye and improve the functional properties of natural cellulosic (cotton) and proteinic (wool) as well as synthetic (polyester) fabrics by using microwave irradiation, with a focus on the kinetic and isothermal adsorption aspects of dyeing processes. The effect of different parameters on fabric dyeability was studied using K/S and the CIE L* a* b*. The effect of dyeing on the multifunctional properties of dyed fabrics was investigated. The adsorption kinetics, isotherms, and mechanism studies of the dyeing process were investigated. The results show that after the fabrics were dyed with the prepared dye, a decorative color was obtained. The dyed fabrics showed very good fastness properties. The dyed fabrics showed excellent UV protection, excellent antimicrobial activity, and very good antioxidant properties. The adsorption kinetics was accurately represented by the pseudo-second-order kinetic model. The Temkin and Nernst models with the best correlation coefficients were discovered to be the most acceptable isotherm models.
