Descrição

[Excerpt] Textile dyeing is recognized for its substantial environmental impact [1, 2]. In response to this challenge, there is an increasing focus on eco-friendly alternatives, including the use of natural dyes derived from plants that not only provide coloration, but also impart unique functional properties to textiles[3]. However, these types of dyes typically exhibit poor color fastness when exposed to washing and light. To address these limitations, heavy metal based mordants are usually employed, which, in turn, contribute to water contamination issues. In this study, the main objective is to establish a multifunctional dyeing method that incorporates Natural Deep Eutectic Solvents (NADES) as sustainable alternatives for both dye dispersion and the extraction of natural dyes [4-6]. The adoption of NADES is expected to reduce water, solvent, auxiliaries, and energy consumption in industrial operations, supporting environmentally friendly practices while maintaining textile quality.
