A process for the production of fast, bright dyeings on wool cloth is described. Reactive dyes applied by a pad‐batch (cold) method yield level dyeings with very high colour yields. Virtually 100% fixation has been obtained with Procion M (ICI) dyes applied to wool from mildly acidic solutions, after batching for up to 24 h at room temperature. Yellowing of wool does not occur under these conditions, which facilitate the production of dyeings of a brightness and fastness that cannot be achieved under conventional dyeing conditions for wool.
