Abstract
A process for coating carpets with fluorochemical emulsions is disclosed. The process comprises treating the fabric with a fluorochemical emulsion then heating, rinsing and, finally, drying the treated fabric. The process is characterized in that the emulsion has a pH and divalent metal ion concentration sufficient to effect transfer of the fluorochemical from the emulsion to the carpet during the heating step.
