Abstract

A method of manufacturing carpet provides for an old art dyeing effect. Specifically, acid and cationic dyes are provided in a solution to a carpet tufted with cationic and acid dye fibers. The carpet is preferably tufted in such a way that there is a relative scarcity of one of the cationic and acid dye fibers at a first width. An abundance of the other dye accumulates in higher concentration than in surrounding areas at the first width. This higher concentration tends to diffuse and/or be moved by other mechanisms to the surrounding areas or widths where the dye attaches to appropriate contacts. This creates at least one of the dark band, a fade and/or a old art dye effect at that location. By precisely controlling the carpet fiber location at the upper surface, the dye solution and the dyeing process, fades and other process can be precisely controlled for repeatable performance as has not been experienced in the prior art.
