History of Natural Dyes: Renewed Interest and Applications

What is it about?

The use of natural dyes dates back to ancient societies, especially those in the Mediterranean, North Africa, Nigeria, South America, and Europe. Colorful fabrics for clothing, rituals, and commerce were created by people in these areas using plants, minerals, and insects. Various methods for extracting dyes and extending the life of colors were developed over time, utilizing compounds known as mordants. The chapter also discusses how contemporary science has utilized these dyes to enhance the process of extracting and utilizing them. Techniques such as microwave-assisted and supercritical fluid extraction enable us to extract more dye in less time and with fewer chemicals. These innovative methods are safer for both humans and the environment. Natural dyes are now utilized in various industries, including textiles, pharmaceuticals, solar technology, and food production. They find applications in cancer therapies, UV-protective materials, sensors, and solar cells.
