Web5.5.4 Disperse dyeing of polyester. Today, almost all polyester is dyed with the small molecular-sized, nonpolar disperse dyes (Gohl and Vilensky, 1983). Before the advent of high-temperature pressurized jet-dyeing machines, disperse dyeing of polyester required the use of fiber-swelling agents such as phenolic-based chemicals. Polyester fiber is a manufactured fiber composed of synthetic linear macromolecules in the chain at least 85% by mass of an ester of diol and benzene-1, 4-dicarboxylic acid (terephthalic acid).
