ABSTRACT:
This invention is a method to dye nylon carpet in a pattern. Improvement comprises adding a reducing agent selected from a group consisting of zinc formaldehyde sulfoxylate, sodium formaldehyde sulfoxylate, thiourea dioxide and mixtures of the formaldehyde sulfoxylate salts with a dye selected from a group consisting of acid, direct, dispersed, fiber reactive and mixtures thereof; also adding an activator for the reducing agent and a stabilizer for the dye bath. Then the dyed carpet is steamed to activate the reducing agent. This makes a dyed pattern that is reproducible, controlled and has differential multicolorations. Each of the dyes is selected for its known characteristic behavior with the activator reducing agent, whether it is completely unaffected, partially affected or completely destroyed. Each dye is applied at a time during the dyeing so that its characteristic effect produces the desired multicoloration effect.
