The dyeing industry utilizes both natural and synthetic sources for colors. Natural dyes are derived from plants (such as indigo and madder), minerals, and insects (like cochineal), while synthetic dyes are created through chemical processes, offering a broader spectrum of vibrant colors and greater colorfastness. Common synthetic dyes include azo dyes and reactive dyes, which are widely used due to their affordability and efficiency. Additionally, advancements in technology have led to the development of eco-friendly synthetic dyes to reduce environmental impact.
