Fixing Agent

Fixing Agent, also known as a color fixing agent, is a chemical compound used to enhance the colorfastness of dyes on fabrics and other materials. It works by converting water-soluble dyes into water-insoluble forms on fibers, thereby improving the wash, sweat, stain, water spot, and friction fastness properties of dyed goods. These agents are particularly important in the textile industry for processes involving reactive, direct, and acid dyes. They can also form cross-links between the dye and fiber, further securing the color's stability. Fixing agents are essential for ensuring the longevity and vibrancy of colors in textiles, making them a critical component in dyeing and printing applications.
