Suitability of Disperse Dyes for Different Applications

American Association of Textile Chemists and Colorists (AATCC) recommends an easy-to-perform immersion test [122], 

Another classification is based on covering up material differences in textured PES fibers. Dyes that have a low fastness to thermo fixing often hardly mark differences in texture they dye at relatively low temperature and are suited to carrier dyeing processes. Dyes that are very fast to thermofixing diffuse slowly into the fiber and must be dyed at high temperature they are not suited for carrier dyeing under atmospheric pressure they tend to mark texture and fixing differences in the fiber. 

According to the recommendation of the Society of Dyers and Colourists, four tests are used to characterize the dyeing properties of disperse dyes [123]  

3) Exhaustion test to determine the temperature range in which the main amount of dye attaches. 

4) Diffusion test (BASF Combi Test [124]) for rate of diffusion in the fiber.
