System- atic further development aimed at the ex- ploitation of the innumerable advantages of the aerodynamic system has led to shorter dyeing processes and massive resource savings. However, a mastery of aerodynamic technology is a prerequisite for the safe use of this process. The basic principle underlying the aero- dynamic system is that the fabric passes through an air-steam mixture emitted from a blower. This means that contrary to a hydraulic dyeing machine, neither a dye bath nor an aqueous medium is needed for fabric transport. In other words, the fabric passage is possible without liquor. The material is in constant motion from feeding to the end of the process, as well as during drainage and filling procedures. Fig. 1 shows the air suction pipe, which has been designed as a filter, in the center of the dyestuff vessel. The blower and the airline, which leads to the transport nozzle, can be seen in the background. The fabric skein is drawn off from the dyestuff vessel by the winder, fed to the nozzle line and then returned to the storage chamber via the cuttler. The storage chamber is fitted with PTFE rods (Fig. 2). PTFE, which is familiar under the brand name Teflon, offers very good non- adher- ence characteristics with the result that the surface of the fabric is well protected. There is no dyeing liquor in the dyestuff This is another development of the very popular jet dyeing machines. The main difference between the Air Flow Machine and Jet Dyeing machine is that the airflow machine utilizes an air jet instead of the water jet for keeping the fabric in circulation. Typically the fabric is allowed to pass into the storage area that has a very small amount of free liquor. This results in a reduction in consumption of water, energy and chemicals. The figure below shows how in an Airflow Machine the bath level is always under the level of the processed textile. Here the fabric does not remain in touch with the liquor (the bath used is below the basket that holds the fabric in circulation). This invariably means that the bath conditions can be altered without having any impact on the process phase of the substrate. Airflow Dyeing Machine Discontinuous processing of textile substrates require more water and energy compared to continuous processes. However, for a long time efforts are undertaken to optimise discontinuous processes with respect to productivity, efficiency and also to minimise energy and water consumption respectively. This lead to dyeing jets. Thereby liquor ratios have been reduced step by step. The latest developments have LR of 1:3 (for woven PES fabric) and 1:4.5 (for woven CO fabric). To achieve such low LR, within the machine (jet), the fabric is moved by moisturised air or a mixture of steam and air only (no liquid) along with a winch. The prepared solutions of dyestuffs, auxiliaries and basic chemicals are injected into the gas stream. The bath level is always below the level of processed textiles in order to maintain low LR. The principle of such an airflow dyeing machine is illustrated. Rinsing is carried in a continuous manner. During the whole rinsing process, the bottom valve is open and rinsing water is discharged without additional contact with the fabric (which is the case in conventional machines) This also allows the discharge of hot bath liquors, also after high-temperature dyeing at 130°C. Thus, in addition to time saving, optimum heat recovery can be performed. The fabric itself is processed with low tension and crease formation is minimised. Description 1. Completely Separated circuit for liquor circulation without getting in touch with the textile 2. Bath less Dyeing operation 3. Rinsing process offers all the added benefits of continuous processing as it is no longer a batch operation 4. Extremely low liquor ratio 5. Virtually nonstop process 6. Comparatively lesser energy requirement due to faster heating/cooling and optimum heat recovery from the hot exhausted dye liquors 7. Reduction in consumption of the chemicals (e.g. salt) dosage of which is based on the amount of dye bath 8. Lesser water consumption savings up to 50% from the conventional Jet dyeing machines 9. Sensitivity towards ecology 10. Economical operation 11. More safety while dyeing.
