Abstract:
1. A method of manufacturing dyed carpet comprising the steps of: providing a tufted carpet with cationic and acid dyeable fibers, wherein there is a relative majority of a first of fiber selected from high or cationic and acid dyeable fibers for a first predetermined width at an upper surface of the carpet; utilizing a continuous dying process with a solution of acid and cationic dye, said solution having a first concentration of acid dye and a second concentration of cationic dye, whereby when dying the carpet at least some of a first dye selected from the group of the acid and cationic dyes in the solution attaches to the first fiber at the first predetermined width thereby providing a higher concentration of a second dye of the acid and the cationic dyes, and then laterally moving the solution and dyeing a second predetermined width near the first predetermined width having second fibers which receive the second dye dyes thereby providing an old art dye effect at a first portion of the second predetermined width as a result of a higher concentration of second dye received by the second fibers than in a second portion of the second predetermined width.
