Color is one the most significant factors for textile fabrics. In addition, color is very important for marketability of textile fabrics. Colorfastness refers to dyes that do not shift hue or fade when exposed to light and other environmental factors and that do not bleed onto other fabrics or materials during storage, processing, use, or care. This study focuses on the use of three different types of dye, disperse, reactive, and direct, on two most commonly used fabrics, cotton and polyester. The fabrics will go under testing to see how much dye is released into the wash by looking at the L, A, B values from the CIELAB spectrometer. The methods done in this study will conclude if the tested fabrics absorb the dyes, making the textiles marketable.
