The fastness of a dye refers to its resistance to fading or running when subjected to various conditions, such as washing, light exposure, and rubbing. High fastness indicates that the dye will retain its color well over time, while low fastness means the color may degrade or bleed. Fastness is an important quality in textiles and other dyed materials, as it affects their durability and appearance. Different dyes and textiles have varying levels of fastness, which can be assessed through standardized testing methods.
