the steam nozzle. The steam nozzle conveys the material wetted with dyeing liquortothefixation chamber-if HByarn is being rocessed,the bulkingprocess is initiated by the effect of the steam - and the yarn is fed otfrom there to travelling yarn column. In test unit 3, the liquor padding device and the yarn centrifuge are'dispensed with. Here, the basic dye can be sprayed on and suctioned off in the space-dyeing device. The capacity of the fixation chamber should be such that the dwell time required for fixing the dye can be reached while ensuring an economical processing speed. The yarn is drawn out of the fixation chamber by the spooler, cooled on the way via the opera- tor aisle, freed of any residual moisture and wound up on the finished commercial bobbin. Depending on the type of material and the thickness of the yarn, production speeds of be- tween 3 /min and 9 /min are possible. The electronically controlled programming unit permits preselectable and reproducible colour effects and, in addition to the basic colour, the 4 space colours and the corresponding mixed colours. The coloured sections can be set between 0.0 and 1 mm, while at the same time avoiding the feared repeat patterning during patterning. The patterning possibilities are virtu- ally unlimited, from mini to long space. The primary field of ap lication will be in the syntheticfibres sector, with emphasis on machine knitting yarn made ?acrylic-Hi3 and -fibres, textured polyamide carpet yarns and staple fibres. 3.
