The behaviour of disperse dyes on wool has been reappraised, with the main emphasis on the effect that blend ratios have on the degree of cross‐staining. It has been found that whilst dyestuff selection is generally unchanged, the dyeing method must be changed completely in order to achieve good results. Blends containing 50% or less of wool may be dyed successfully by a one‐bath method, but wool‐rich blends need to be dyed by a novel two‐bath method. The results of these studies, and the dyeing method that is being proposed, are discussed.
