“…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.

Dyeing plays a vital role in the textile industry, however, associated health and environmental issues have raised significant concerns regarding the types of dyes used. Among these, natural dyes, particularly those derived from plants, exhibit superior safety and environmental performance, making them a more sustainable alternative. Moreover, fabrics dyed with plant dyes can acquire diverse functional properties, including antimicrobial characteristics, attributed to various active ingredients present in plants during the dyeing process. With increasing environmental consciousness and the rising demand for functional fabrics, natural plant dyes have garnered growing attention. In our research, a systemic review of the antimicrobial properties of plant dyes in the textile field was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method. A literature search was executed through the PubMed and Web of Science databases, from which 132 articles were selected. The results indicate that the overall number of publications in this field is on the rise, especially showing a significant increase in the past 7 years, demonstrating substantial research value and potential. Furthermore, this study conducted an analysis of the content included in the literature, summarizing the different standards and characteristics of antimicrobial testing, with a focus on revealing the antimicrobial mechanisms of plant dyes. It also discussed the mordants and other treatment methods that can effectively enhance the antimicrobial properties of plant dyeing. Building on this foundation, this review discusses the advantages, application potential, and future research directions of antimicrobial natural dyes derived from plants. Through this review, relevant researchers can gain a clearer understanding of the current state and development trends of plant-based natural dyes in terms of antimicrobial properties, thereby promoting further exploration in this field.
