A process for applying water-soluble chemicals to flexible substrates, e.g., textile fibers, yarns, non-woven, loomed, tufted woven and knit materials, paper and the like, which employs a readily removable carrier formulation at lower temperatures under ambient pressures consisting of preparing an aqueous-oil emulsion of the chemical and its attendant assistants, catalysts or reactive or non-reactive co-chemicals, surface active agent(s) in 1 to 35 percent by weight water and 98 to 40 percent by weight of a halogenated hydrocarbon solvent boiling between about 40 DEG to about 165 DEG C., applying the emulsion to a flexible substrate by dipping, immersing, flooding, doctoring, spraying or the like, introducing the so-wetted substrate into a zone filled with the vapors of the halogenated solvent which is at a temperature at or above the boiling point of the solvent of the emulsion, maintaining the substrate in said vapors for a time sufficient to remove the water and solvent from the substrate, and removing the substrate from said zone in a dry condition retaining the chemical(s) thereon or in.
