The influence of hueing dye on the fabric b * value and CIE whiteness during home laundry was investigated using crystal violet dye to study the accumulation mechanism on fabric samples. Fabrics treated with the crystal violet dye had a lower b * value and a higher CIE whiteness. The dye accumulation was much higher on nylon or nylon/lycra blends than on cotton and polyester fabrics. The fabric surface charge and surface energy were also studied, and the dye‐fiber interaction was investigated based on fiber and dye molecular structure. The study indicates: (1) the electrostatic adsorption is the main contributor to the deposition and accumulation of hueing dyes on fabrics; (2) fabric surface energy may play an important role in the dye‐fiber interaction. The more hydrophobic the fiber surface, the less dye accumulates on the fabric during home laundry.
