ABSTRACT:
Compositions for use as dye assistants are formed from a non-phenolic aromatic swelling agent for the fiber to be dyed mixed with just enough dispersant to cause a non-foaming emulsion upon dilution of the dye assistant in water, but not enough dispersant to interfere with the swelling process of the fiber by the dye assistant. Thus, the swelling agent is mixed with the minimum amount of surfactant required for the production of an emulsion and dispersion of the dye with little or no foaming in the dye bath. Formulations can also be prepared having higher levels of water which are non-flammable.
