A first set of the chambers can include a consecutive series of dye chambers through which the fabric load and a single dye bath are successively transferred and in which the dye bath is heated to about the same temperature in each of the dye chambers. A first chamber in the series of dye chambers and each chamber subsequent to the dye chambers can be adapted to receive a fresh water bath. A last chamber in the series of dye chambers and each subsequent chamber can be adapted to drain the bath in those chambers. The weight ratio of dye bath mixture-to-fabric can be about 5:1. The dye bath can include a fiber reactive dye or a direct fabric dye.02-02-2012
