The Kinetics of Wool Dyeing—Some Effects of Alcohols on Wool Dyeing Rates

Abstract
The action of alcohols in the "solvent dyeing" of wool is considered and, from an analysis based on the diffusion characteristics of the fiber, the increased dyeing rates obtained are attributed largely to faster movement of the dye within the fiber. The reduced resistance to dye diffusion within the fiber is associated with the presence of the alcohol during the diffusion process and also with the removal of greasy material from the interior of the fiber by the alcohol-water phase.
