Description

The innovation relates to improvements in reel dyeing machines. Various types of reel dyeing machines have been proposed for the purpose of stretching and Preventing puckering, especially of thermoplastic fabrics, during dyeing, however, did not quite work satisfactory and the object of the present innovation is to improve the operation of such machines.

A reel dyeing machine consists of a closed, lye-containing vessel 1 with an outside Pump 2 and a heat exchanger 3, the dye liquor through an outer pipe 4 to an inlet and control valve 5 circulates to the vessel. The vessel 1 is provided with a false bottom 6 to provide a return passage 7 for the To create lye underneath the wrong soil. The false bottom has holes 8 at the end, which is remote from the pump to provide access from inside the chamber to the return passage 7.

Above the liquor inlet pipe 5 at the rear end of the vessel, a fabric dispensing roller 9 is in engagement with a Removal roller Io attached. A front roller 11 is attached to the front of the machine and a control flap slide or throttle valve 12 arranged for a front jet nozzle. Another regulating or throttle valve 13 is located at the rear of the machine.

An external water supply with an independent pump 14 feeds an overhead spray ring 15, while a The folding spray can is fed from the inlet control valve 5.

A salt / paint box 17 is provided outside the machine. Flap doors 18, 19 are at the front and rear ends of the vessel and also a tissue removal roller 18a with an independent drive at the front end.

An automatic vent la is provided in the upper part of the vessel, which is pneumatic during the cooling process is operated. The top and sides of the vessel are insulated against heat loss.

The inlet for the pump 2 is provided in a collector 2o at the rear end of the vessel, the liquor through the pump 2 is sucked in, through a plate-like heat exchanger 3 and from there to a split channel 4, 4a travels to feed the front and rear spray tubes. It should be noted that the spray tubes over the run the entire width of the vessel and are designed so that they result in a thin water surface and not that, what is normally expected from a shower head.

Both tubes are regulated by the throttle valves 12, 13. In the case of the rear sprayer 13 is the The lye spray angle downwards and forwards (simultaneously) and a reciprocating movement of the inlet control valve 5 applied, which gives the spraying an "on-off" state. The purpose of all of this is, tissue A.

channel or passage 7 and from there to pump 2o and pump 2 is withdrawn. The tissue migrates through a pivotably mounted dowel rail 21, which in the event of entanglement with a (not shown) trigger switch is connected, then over the front roller 11 and is pushed through the underflow 7 and over the rear roller 9, where the Cycle begins again. The strands of tissue are laid in continuous single loops, as described above.

The purpose of the front spray nozzle is to increase the flow of liquor through the underflow or channel 7 so that the increase in the flow of tissue is compensated for by a corresponding increase in the flow of lye. While its course through this channel 7, the tissue expands into the liquor stream and is formed every time it gets back into the vessel 1, back in a different shape.

On its way from the pump 2 to the front spray nozzle through the caustic duct 4, caustic can be tapped from this duct and to the salt or paint box 17 on the side of the machine. This box is by means of gravity connected to the collector 2o at the rear end of the machine to dilute the liquid dyes and chemicals before they get into the main staining vessel, and to dissolve the solid chemicals (such as salts) so that they are in a liquid state get into the staining vessel.

The overhead spray nozzles 15 can alternate with the dye liquor or a source of pure water. The spray nozzles are arranged so that they the Cover the entire surface of the vessel with a comparatively fine spray of small droplets. When connected The purpose of the dye liquor is to keep the fabric moist with the liquor, if the liquor ratios are very low be used, because under these circumstances there are actually correct proportions above the lye level. This moistening with the dye liquor is only necessary in special cases, even if the tissue is not fully immersed.

However, the use of overhead spray nozzles 15 is important as a pure water shower for removing residual chemicals after the actual dyeing process. A fundamental feature of the machine is that the fabric is flat is spread in a very thin mass over a comparatively wide area. Its purpose is above all to process the fabric in a completely relaxed form and also to rinse off paint residues more thoroughly with considerable To achieve a reduction in the amount of flush water required. When the dyeing stage is finished, will the contents of the vessel are drained and the dye liquor drains off. However, all wet fabrics retain varying amounts of the

This dye liquor returns in itself and in some cases this can be five times the weight of the fabric. this in turn, contaminates the pure water that is used for rinsing after dyeing, so that a proportion

There can be an automatic control to turn on the pure water spray nozzles with the opening of the pull-in valve 23. The machine can run at speeds of 40 yards / min, (approx. 36.4 m / min) without loss of performance compared to existing machines and with improved quality ' to run.
