Abstract
In a continuous application process with post-steaming, SAC's having molecular size (hydrodynamic volume) defined by elution volume (Ve) determined by Size Exclusion Chromatography (SEC) of between 6.3 and 6.5 ml. using the procedure described, are such that they are not too small so that migration into the fiber occurs (reduces ring dyeing effect) nor are they too large such that they require extremely long steaming times or the use of swelling agents to be effective. This is independent of the degree of sulfonation of the SAC.
