This paper is a reviewing account on the application of polymeric dyes in textiles. Polymeric dyes are classified as crosslinking polymeric dyes, disperse polymeric dyes, “fiber-reactive” polymeric dyes and acidic polymeric dyes. Excellent color fastnesses and dyeing properties are shown when fibers are treated by these polymeric dyes. Crosslinking polymeric dyes show excellent fixation (reaching 99%); disperse polymeric dyes show excellent light fastness (8 grade); “fiber-reactive”polymeric dyes could form chemical covalent bonds with fiber, exhibiting excellent washing fastness; acidic polymeric dyes showing the same fastness properties as the corresponding monomeric dyes, and furthermore the thermal stability is enhanced.
