Abstract
A dye fixing section in a foam indigo dyeing machine for dyeing traveling sheets of textile yarn. The dye fixing section receives traveling sheets of yarn to which indigo dye in leuco form has been applied and penetrated partially through the yarn. Oxygen is applied to the substrate to set the dye at the level of penetration achieved as it enters the dye fixing section, to produce yarns in the sheet with outer dyed rings and undyed cores.
