Textile dyeing process: multicolor pattern dyeing of tufted nylon carpet

摘要

A continuous process for dyeing a pre-wetted carpet includes the step of printing, in one dye color, a desired pattern on the tufts, compressing those of the tufts receiving the dye in the process. The tufted printed surface of the carpet is then covered with a viscous water- soluble first gum and drops of a second dye, which is less viscous than the first gum, over the viscous gum-wetted tufts. Drops of a water- soluble second gum which is less viscous than the first gum, are then applied to the tufted surface and then a third dye which is substantially less viscous than the second dye is applied over the entire tufted surface of the carpet.
