摘要： The present invention relates to a process for dyeing cellulosic warp yarns with indigo by applying a leucoindigo foam to the warp yarns and subsequently oxidizing the leucoindigo to indigo, wherein the warp yarns are led through an entry opening into a sealed foam chamber and have leucoindigo foam applied to them therein before they reemerge from the foam chamber through an exit opening, the longitudinal tension of the warp yarns being closed loop controlled such that they are in a state of free suspension within the foam chamber.
