In the context of the need to develop sustainable textile technologies, this research investigates the application of Prunus spinosa extracts as environmentally friendly coloring agents. The fruits and bark of this species are rich sources of bioactive compounds, including tannins, flavonoids, and anthocyanins, characterized by antioxidant, antimicrobial, and dyeing properties, thus providing a viable alternative to synthetic dyes. Pigment extraction from Prunus spinosa fruits can be conducted through various methods such as maceration, boiling, and pressing. The chemical composition of the extracts can be characterized using advanced analytical techniques, including High-Performance Liquid Chromatography (HPLC), Proton Nuclear Magnetic Resonance (1H-NMR), and Fourier Transform Infrared Spectroscopy (FTIR). Employing these extracts in environmentally friendly textile dyeing processes significantly contributes to the reduction of environmental pollution by eliminating the necessity of harmful chemical agents. The stability and fixation properties of these natural dyes can be evaluated using spectroscopic analyses, wash, light, and rub fastness tests, as well as colorimetric measurements. Literature studies have indicated a high affinity of these natural dyes towards natural textile fibers, such as cotton and wool, ensuring strong adherence and enhanced color durability. In addition to ecological advantages, this method supports the development of a more sustainable textile industry by providing products with additional functional properties, such as ultraviolet (UV) protection and antimicrobial activity. Therefore, the valorization of Prunus spinosa extracts in textile dyeing aligns with green chemistry principles, promoting innovative and eco-friendly alternatives to conventional dyes. This approach represents a significant step towards reducing the ecological impact of the textile industry by demonstrating the feasibility of utilizing natural resources in sustainable processes. Future studies will focus on extending the applicability of these natural dyes to synthetic fibers, optimizing extraction procedures, and maximizing pigment fixation efficiency. Thus, the application of Prunus spinosa extracts as natural coloring agents not only offers a viable and environmentally friendly alternative to synthetic dyes, thereby reducing the negative environmental impact of the textile industry but also opens new perspectives for the development of functional textiles with antimicrobial and UV-protective properties, contributing to the transition towards more sustainable production processes aligned with circular economy and green chemistry principles.
