Dye compactibility refers to the ability of a dye to be effectively incorporated into a substrate, such as fabric or plastic, without losing its color properties or causing defects. This characteristic is crucial in industries like textiles and plastics, where uniform color application is essential for product quality. High compactibility ensures that the dye adheres well and remains stable during processing and use. Factors influencing dye compactibility include the chemical structure of the dye, the nature of the substrate, and the processing conditions.
