ABSTRACT:
A chemical, such as a dye, is applied to a textile substrate, such as carpet, by continuously moving the substrate past an application position. At the application position a liquid formulation containing the chemical, heated to a temperature below the boiling point thereof, is sprayed toward the substrate, thereby driving the chemical into the substrate. The temperature of the spray is controlled such that the dye contacts the substrate at a temperature sufficient to achieve substantially instantaneous fixation.
