Definitions

  • the invention relates to a method and a device for the preparation of dye liquors, in particular for textile dyeing or aftertreatment systems, the textiles being treated with heated dye liquors in one or more dyeing chambers connected in series.
  • the textiles to be dyed are moved back and forth several times in the back and forth gear by the dye liquors provided in the chamber or chambers.
  • This mechanical movement of the textiles within the dye liquor also takes place for color pre-treatment and post-treatment and serves to intensify the coloring and color matching.
  • the dyeing and washing liquors can be brought to a temperature below the boiling point of up to 90 °, which in the known arrangements is done by laying heating pipes within a lower chamber section that come into contact with the dyeing liquor.
  • the invention is accordingly based on the object of providing a method and a device of the type mentioned at the outset with which it is possible to keep the disposal fraction as low as possible and, if appropriate, to do without coloring aids altogether.
  • the textiles to be treated are drawn continuously through the associated device, with the use of deflection systems in each case a longer, always Textile section running in the same direction in the chambers is treated with the dye liquor and the dye liquor is subjected to a constantly repeating color exchange by removal from the chamber and reintroduction.
  • the frequency of the fleet exchange is expediently chosen so that a fleet exchange of 30 to 60 times takes place during the passage of a textile section with a length of approximately 300 m. In this way, the textile section is subjected to renewed application of color every 50 m with exchanged dye liquor.
  • the throughput speed of the textile section can be about 10 to 20 m per minute. With this throughput speed and the resulting throughput length, the overall performance of the system is normally achieved.
  • the color exchange is of course only an application of ink with a liquor that has been removed from the container and filtered and cleaned or processed in the manner described below and then returned to the container elsewhere.
  • a particular advantage of the arrangement according to the invention and of the method according to the invention is therefore that due to the supply of prepared, that is to say cleaned and filtered, liquor of the same substance, the introduction of coloring aids for coloring, as in the known arrangements, can be dispensed with entirely.
  • This has the further great advantage that the dye liquor can be used again and again in the cycle, with its amount only reducing to the extent that certain residues of the dye liquor remain in the textile.
  • the application of color aids is completely unnecessary. As a result, they do not need to be supplied or disposed of in any way, which has the further advantage that the textiles themselves no longer have to be subjected to post-treatment by the dealer or consumer, and washing is no longer necessary.
  • Another advantage is that in the arrangement according to the invention only a single installation is required for all dyeing and finishing stages, so that intermediate drying of the textile can also be avoided.
  • the textile piece is moved by the dye liquor
  • the dye liquor and not the textile is moved in a particularly advantageous manner, i.e. this only insofar as the feed through the system requires it.
  • the arrangement according to the invention therefore makes it possible, particularly in the case of particularly dense textiles, to dye them without sacrificing the advantages mentioned, for example by directing high-pressure nozzles onto the textile within the treatment chamber and introducing the dye liquor into the textile via these nozzles.
  • the high pressure nozzles can work with a pressure of 16 bar.
  • a differential pressure is formed between two chambers, and this pressure can also be used to subject dense textiles to the penetration of the dye liquor into their fabric components.
  • the preparation of the dye liquor is primarily used for cleaning by filtering the dye liquor to remove impure constituents from the dye liquor, i.e. also those loose components that are produced as residues in textile production. Filtering is also intended to remove pesticides and other toxins from the textile, whereby the dye liquor can be treated up to ultrafiltration.
  • Another task of liquor preparation is an additional dye supply, which of course must not lead to a higher liquid content, in particular to a higher water content.
  • the dye liquor is subjected to a steam treatment in which the additional water associated with the dye feed is evaporated again, so that the conditions remain unchanged despite the dye feed.
  • a certain amount of water is supplied to the dye liquor, which is then removed again in the form of steam, so that the relative amounts of liquor / water remain unchanged.
  • the steam development is carried out directly from the liquor to be exchanged, so that the medium is the steam developed from the liquor itself.
  • This steam generated in this way can be used simultaneously in the first treatment stage, that is to say in the application chamber, in order, for example, to facilitate and improve the application of the color to the textiles.
  • the steam does not contain any dye, so that clean steam can be obtained from the dye liquor.
  • the arrangement according to the invention consequently makes it possible to use the same dye liquor over very long periods of time. Due to the color preparation in the manner described above, a fresh, i.e. revised and cleaned paint fleet available. Since the process according to the invention produces steam which is pure and forms clear water in its condensation, it is possible to use this clear water for other color levels within the same system.
  • a device for carrying out the method according to the invention is therefore a processing system for the dye liquor to be exchanged in each case.
  • the device consists of two essentially annularly arranged heat exchanger elements, of which the outer ring is connected to the liquor and the inner ring with heating pipes which serve to generate steam by being acted upon by the liquor. This proportion has already become so thin due to the development of steam that the proportion of color is reduced compared to the original color liquor.
  • the inner ring is designed as a steam pipe, with a cylindrical upper section and a lower section; the color liquor changes into pure steam with increasing steam development in the upper section of the tube.
  • the processing device can be provided with an additional heater, which can consist of an oil heater, an electric heater or the like, which is accommodated in pipes which are arranged in the bottom region of the device.
  • an additional heater which can consist of an oil heater, an electric heater or the like, which is accommodated in pipes which are arranged in the bottom region of the device.
  • the entire device is provided with insulation, with a double jacket which is filled with water being arranged between the inner evaporation tube and the outer annular liquor chamber , whereby the water continuously flows through the double jacket when cold (approx. 20 ° C).
  • the flow is caused by a pump, the flow rate of the water being adjustable so that the temperature to be maintained can be set precisely on the basis of the flow rate. It is therefore also easy to set the temperatures required for different colors.
  • the heating area which is slatted into the steam pipe is enlarged, so that that part of the liquor which enters this heating area can be supplied to the evaporation relatively quickly.
  • compressed air can also be introduced into the evaporation tube.
  • a textile tape 1 to be dyed is unwound from a supply roll 2 and, via a stand device 3, in which it is deflected several times, is supplied to a plurality of color liquor chambers 4 connected in series, in which the textile strip which is deflected is subjected to a continuous pass through the To enable dye liquor chambers 4 despite a relatively large length of the textile tape to be dyed.
  • the textile strip 1 is then fed to a drying chamber 5, in which it is likewise deflected several times in order to be finally wound up on a further supply roll 6.
  • the middle section of the system with the dye liquor chambers 4, in which the textile tape 1 is dyed, is important for the invention.
  • the individual continuously running textile strip preferably has a length of about 300 m, whereby - as provided according to the invention - a dye liquor exchange takes place about 30 to 60 times during the passage of such a strip.
  • the dye liquors or ink loading chambers 4 are each assigned dye liquor cleaning devices 7, to which the buffer stores 8 the liquor of paint to be cleaned and reprocessed is fed from top to bottom in the direction of the arrows 9, an evaporation device 10 being assigned to the cleaning devices 7 in each case in the case of clarified exemplary embodiments.
  • Fig. 2 shows one of the evaporators in detail.
  • the liquor to be exchanged is fed in the direction of arrow 11 via a schematically indicated fleet testing and metering device 12, which has several chambers, and via hydrogenation devices 13 to an annular jacket space 14, which has a relatively thick-walled insulating layer 15 on the outside and one on the inside Heat exchanger 16 is provided.
  • the heat exchanger 16 surrounds heating tubes 17 arranged in a circle (see FIG. 3), by means of which the dye liquor components contained in the annular heat exchanger 16 are heated in such a way that a water component evaporates and is discharged to the outside in the direction of arrow 18 and the ink liquor chambers 4 (see FIG. 1) is fed again.
  • the annular heat exchanger 16 consists of an upper section 16a of cylindrical shape, which is adjoined by a lower section 16b, which has a conical shape in order to cover a larger quantity range of the ink liquor 19.
  • Compressed air can be supplied to the overall arrangement via a line 20 coming from below in order to promote the upward flow and in order to be able to subject it to high-pressure textiles with a high pressure.
  • additional heating in the form of additional heating tubes 21 arranged in the bottom area can be provided.
  • the paint liquor can be supplemented by a liquor feed line 22 coming from below and acted upon by a pump.
