mordants

Mordants are substances used in dyeing textiles to help fix the dye to the fabric, ensuring the color is vibrant and long-lasting. They work by forming a chemical bond between the dye and the fibers, increasing colorfastness. Common mordants include metals like alum, iron, or chromium. The choice of mordant can influence the hue and intensity of the dyed material, allowing for variations in color. Essentially, mordants act as a bridge that securely attaches the dye to the fabric, making the color resistant to washing and light exposure.
