ABSTRACT
Levelness in package dyeing can be described quantitatively and an unlevelness parameter defined using simple model systems. Factors which determine levelness in industrial dyeing procedures are discussed including the role of the fiber surface in dyeing acrylic fibers, the leveling ability of disperse dyes for polyester and the importance of liquor flow and its uniformity when dyeing cellulosic fibers. If these factors are considered as well as control of exhaustion or fixation, levelness can be improved or dyeing time reduced. Further optimization with the use of simple computer programs allows for improved dyeing results.
