Colorfastness is a term used in the textile industry to describe the resistance of a fabric to fading or discoloration when exposed to light, water, or other environmental factors. It is a critical property for textiles, as it ensures that the color of the fabric remains vibrant and true to the original shade over time. The colorfastness of a fabric is typically rated on a scale, with higher ratings indicating greater resistance to fading.

Several factors can affect the colorfastness of a fabric, including the type of dye used, the method of dyeing, and the composition of the fabric itself. For example, synthetic fibers such as polyester and nylon are generally more colorfast than natural fibers like cotton and wool, as they are less prone to fading and discoloration. Additionally, the use of mordants, which are substances that help dyes adhere to the fabric, can improve the colorfastness of a fabric.

Colorfastness is an important consideration for consumers when selecting textiles for clothing, home decor, and other applications. It ensures that the color of the fabric will remain consistent and vibrant over time, regardless of exposure to light, water, or other environmental factors. In the textile industry, colorfastness is typically tested using standardized methods and rated on a scale to provide consumers with reliable information about the durability of the fabric's color.
