liquor spray nozzles 3.3 Improvements on units 2 and 3 and/or expansion with new yarn winders Experiments on unit 3 showed that, according to the experience.gained with unit 2, the arran- gement of thespace-dyeing units and dyespray nozzles hadto bechanged toeliminatesoiling of the yarn. This improvement will be incorporated in the pilot plant. At this time, experiments and profitability analyses indicate that the machine knitting yarns (Nm 1/2 - Nm to be processed with unit 3 can be moreeconomically fixed in vacuum steamer, due to the small quantiti,of yarn and the relatively long dr fixing time. The final choiceforthedyefixingofthemac ine knitting yarnscan bemadeatt egiventime,following corresponding experiments on the pilot plant. 3.4 Improvement of the liquor spray nozzles ) Longer service life Constant dyeing and functional tests with the spray nozzles showed that corrosion primarily occurs with various basic dye combinations in connection with the acetic acid used as the sol- vent. Series of experiments and metallurgical studies were carried out with the support of the dye manufacturers and in close cooperation with Messrs. BOSCH. After consultations with the ' special-steel manufacturers, material was found which, accordin to current test results, holds the promise that corrosion will be avoided in the event of possib?econtact between chlo- ride and acetic acid during dye application. Wear tests erformed on the BOSCH test rig indicate that satisfactory service life can be expected orthe nozzles made from the new material Practical experiments have confirmed this result ) Greater reliability of colour uniformity from one processing location to another After determining nozzle material which resists the dyeing liquor, investigations and experi- ments were carried out with the goal of integrating the function of the closing mechanism of the BOSCH nozzle with that of spray jet formation in the nozzle mouthpiece(1ocated in front) i
