<p>RCA 72,838 TEXTILE DYEING PROCESS A continuous process for dyeing a carpet includes the step of applying a viscous, water soluble colorless gum layer over the tufted face of the carpet. Drops of first and second dyes less viscous than the gum are applied over the gum-wetted carpet face. A third dye, which is substantially less viscous than the gum and then the first and second dyes, is applied over the entire tufted surface of the carpet. The carpet may be pre-wetted before the gum layer is applied.</p> |
