Abstract: Methods and apparatus for fixing dye to pile fabrics such as carpet material by employing the electrical conductivity of the wet carpet itself for the purpose of heating the carpet and dye to a temperature sufficient to fix the dye. The present apparatus, in the space of several feet along the length of a continuous carpet treating apparatus, performs the same function as a conventional carpet steamer, which is typically several hundred feet in length. In one specific form, the electric current is passed in a direction through the thickness of the carpet employing a pair of flat plate-like electrodes which contact the front and back surface of the carpet. In another specific form, the electric current is passed through the carpet in a direction generally parallel to a surface of the carpet, e.g. longitudinally, employing electrodes on the back surface of the carpet which do not disturb any pattern which may be printed on the carpet during the dyeing process.
