Color fastness is the quality benchmark of choice across the textile industry, as it directly determines a fabric’s appearance retention, durability, and market reputation. Among all fastness properties, color fastness to wash is the most widely evaluated, as regular laundering is the leading cause of color fading and staining in everyday textile use.
