Abstract
An apparatus for dyeing a textile substrate using a plurality of applicators that each apply an increment of a total dye application. In one form a reduced indigo dye in a leuco-state is applied in an inert atmosphere substantially isolated from oxidizing substances. In another form the foamed dye is applied while open to the atmosphere. In both forms holddown rollers or inverted applicators are located between applicators at decreasing depths to minimize increases in tension as the substrate travels over successive applicator faces.
