Research overview:
To solve the problem of yellowing of indigo-dyed products during production or storage, we aim at establishing direct preventive measures based on the characteristics of the dye. Since the dye shows characteristic dying and coloring properties on fibers, the relationship of the properties with its fading is investigated. The relationship of shelf conditions for the dyed products with decomposition products of indigo is also examined to identify factors contributing to yellowing, and effective preventive measures against yellowing are proposed.
