A polyester package dyeing system based upon water and 2‐ethoxyethanol is described. The process is similar to and a natural development of the silicone—perchloroethylene system discussed in Part I [1]. It is a bicomponent homogeneous system. Water replaces silicone as the bulking medium or antisolvent and 2‐ethoxyethanol replaces perchloroethylene as the dye solvent. Potentially it is a more versatile system than Dacsol, e.g. cotton‐polyester fibre blends can be dyed. High yields result from a low 2‐ethoxyethanol: fibre ratio. Existing disperse dyes in diluent‐free or commercial forms are suitable. Water quality, however, is important.
