ABSTRACT:
A textile sheet strand is dyed by conducting it in at least two separate passes around an annular path having a first path section in a dye vat and a section path section in a gas-treatment location. In the dye vat the strand is contacted with a liquid dye bath in each of the paths, and the excess dye is squeezed out of at least two of the passes at the same time by pinch rollers immediately downstream of the dye vat. In the gas-treatment location the passes of the strand are each treated with a gas to fix the dye.
