Abstract

The dyeing behaviors of poly(trimethylene terephthalate)/poly(ethylene terephthalate blends were investigated. The influence of dyeing time and temperature on dye uptake was examined. The effect of blend levels on the quality of the dyed goods, such as dye uptake, shade depth, and colorfastness, was explored with dyeing conditions for different blend levels of PTT/PET recommended. Due to the strong disperse dye affinity and the atmospheric dyeability of PTT, PTT/PET mixtures were pattern colored in a single dyebath with only disperse dyes. Possible approaches to such pattern coloring and examples of the cross dyeing results are also discussed. The color quality of the dyed PTT/PET blends was very close to the 100% PET. The improved fabric performance properties and the disperse cross dyeing ability provide this new product with some novel opportunities.
