The addition of a nonionic levelling agent to a dyebath containing a mixture of three disperse dyes in equal proportions and having similar hues (all in the red—yellow sector of colour space) significantly improved their compatibility, especially at higher applied depths of 3.0% and 4.5%. The dyed samples were measured for the differences in their colour coordinates with respect to the undyed substrate on a spectrophotometer attached to an IBM personal computer. The plots of Δ L * vs Δ C * ab , Δ L * vs K/S , Δ b * vs Δ a *, Δ a * vs K/S and Δ 6 * vs K/S clearly indicated the improvement in compatibility of the dye mixture.
