Abstract
In a process and apparatus for coloring a pile fabric, liquid coloring material is introduced into compartments, and the pile fabric is pressed face downwardly into the compartments. In order to provide regions wherein different colors are distinct from one another, a resilient barrier is provided between compartments to which different colored liquid coloring material is introduced and in order to provide areas of the pile fabric wherein the colors are blended, liquid coloring material of different colors is introduced into the compartments in regions not separated by a resilient barrier.
