Apparatus for dyeing yarn of the type wherein yarn is wound on cones mounted on a carrier in a vessel fitted with inlet and outlet conduits for the dye liquor, whereby the latter may be circulated in two modes, namely, in a first mode from the inside of the cones, and therethrough to the outside; and in a second mode vice-versa, and including means for operating in the first mode such that the amount of circulating dye liquor is little more than just sufficient to fill the inside of the cones and the perforate carrier, thus leaving the major part of the vessel space outside the volume occupied by the cones and the perforate carrier substantially free of dye liquor.
