The axial distance (4) between the end faces of the package (5) and the outermost holes (1) of the tube (2) is 0.6 to 1.2 times the distance between the holes and the outer surface of the yarn package. The cross-sectional throughflow area of all the holes in the tube is not larger than 9 cm<2> for a yarn weight of the package of 1 kg. So that the inner layers do not undergo a more intensive dyeing in the region by which they cover the holes, in each hole the ratio of the smallest hole cross-section to the hole cross-section on the outside of the tube is at least 1 : 3. <IMAGE>
