A Study on Color Reproducibility of Disperse Dyestuff for Polyester

Dyeing is the process of providing color to a textile through color phenomenon resulting from the complex interaction of the dye and the textile. Thus, it is essential for laboratory to grasp understanding of dyeing behavior from 3-combination dye group together with high compatibility amongst themselves. To increase the color reproducibility in the industry, measurement and comparison of the absorption rate, K/S value, and the color difference of commonly used 3-combination disperse dyestuff in the polyester dye industry revealed the following conclusions: 1. The higher the Dye absorption rate of the 3-combination dyestuff, the higher the Color reproducibility is when applied to Deep shade target colors. 2. If the graph of K/S value for 3-combination dyestuff is linear, it has excellent Build-up property, and if dye behavior of each 3-combination dyestuff is similar, then the dye group has good Compatibility, thus good Color reproducibility. 3. The better the Compatibility of the 3-combination dyestuff, the lower the Color difference was between the lab and the industry, thus producing good Color reproducibility.
