What are hot brand, medium brand and cold brand dyes?
It is not common practice to specify dye types in this manner, for example, monochlorotriazine dyes have been given the name ‘hot brand’ whilst vinyl sulphone dyes have been termed ‘warm brand’ using this system it is not possible to give a term to mixed bi-functional dyes since they have one monochlorotriazine group and one vinyl sulphone group.
