Definitions
- the invention relates to a process for dyeing continuous textiles according to the preamble of claim 1 and an apparatus for performing the method.
- Such methods and devices are used for e.g. Indigo dyeing of textiles used, in which the dye sparingly soluble in water with the aid of alkali and reducing agent is converted into a fiber-affine water-soluble form.
- the dye can dye the fibers of textiles, which is also called padding.
- Other vat dyes such as indanthrene and Sulfur dyes are usable.
- the object of the invention is a process for dyeing textiles, in which these padded several times with dyes and then greened in an oxidation zone be improved so that saves significant amounts of chemicals and at the same time achieve a consistent dyeing result.
- a Another object is the provision of a device for carrying out the method.
- the first object is solved by the characterizing features of claim 1.
- the fact that oxygen displaces from the textiles immediately before each padding is, whereby a re-penetration of oxygen into the textiles in each case before the greening Preventing unwanted oxygen is excluded in the dyebath arrives.
- Oxygen in the dyebath causes oxidation of the dyestuff, which does not cause it is more fiber affine, that is, it is water insoluble and can no longer be effective Dyeing be used. Furthermore, the oxygen causes auxiliary substances such as reducing agents and alkali are consumed and / or converted into an ineffective form. Overall, so in the known method more dyes and auxiliaries in the Dyeing baths are dosed as needed for the actual dyeing.
- the method according to the invention avoids these disadvantages and thus prevents that dyes and auxiliaries are oxidized without being used for the dyeing process to be able to. Compared to the known methods is a saving from 30 to 40% of the total consumption of chemicals with corresponding Cost reduction possible. Furthermore, a more uniform coloring result is achieved.
- Claim 6 solves the second task.
- wash water according to claim 3 carries chemicals that according to the lost to the known processes with the wastewater, in the dyeing process, so they can be used again.
- the washing water is oxygen-free, has the required pH value and is therefore ideal for the displacement of oxygen from the textiles suitable.
- the oxygen-free atmosphere between the displacement of oxygen and the subsequent greening prevents the textiles from wetting or when wetting Take up oxygen again with dyestuff and then enter into the dyebath.
- the Maintaining the once oxygen-free atmosphere is very low Effort possible because they are practical in operation through the running textiles is not affected
- Nitrogen according to claim 5 is available in an inert and inexpensive.
- the invention is based on a simplified illustrated embodiment of Threads further explained.
- the figure shows a diagram of a part of the device according to the invention for dyeing of threads.
- a device comprises a plurality of wetting stages 1 and each wetting stage 1 downstream oxidation routes 2 and a washing device 3. Furthermore, the device does not - - means for feeding threads 4 in which the threads are e.g. in a creel unwound from spools and directed to dyeing, and means for drying the dyed threads 4.
- Each wetting stage 1 comprises means 5 for displacing oxygen from the threads 4, a dyeing trough 6 and a second squeezing 7th
- the means for displacing 5 include a trough 8 with at least a first guide roller 9 and arranged at the exit of the threads 4 from the trough 8 first Quetschwerk 10. At the trough 8, an overflow pipe 11 is fixed, which with a Outflow is connected.
- the dyeing trough 6 At a short distance in the direction of the threads 4 behind the first squeezing 10 is the dyeing trough 6 with a plurality of second guide rollers 12 is arranged. To the second guide rollers 12, the threads 4 are guided so that this sufficient long distance in the dyeing trough 6 run. In the outlet area of the Därbetrogs 6 above a Klarbeflottenspiegels the second squeezer 7 is arranged so that squeezed Fleet back into the dyeing trough 6 flows.
- a hood 13 is arranged so that she dives with a part into the fleet of trough 8 and by the way against the trough 8, the dyeing trough 6 and the second squeezing 7 largely airtight connected.
- the hood 13 is connected via a line, not shown, to a Nitrogen source connectable.
- the washing device 3 is arranged. These comprises a washing trough 14 and a series of third deflecting rollers 15 and third Crushing 16.
- the washing trough 14 is connected by a line 17 with branches connected to each of the troughs 8; depending on the local conditions is in the line 17 arranged a pump 18.
- the washing device 3 is followed by an unillustrated dryer.
- the threads 4 are withdrawn from the creel and as a group of threads for dyeing, wherein at least one described in the following dyeing is going through.
- the threads 4, which have absorbed oxygen from the air, are initially in the trough 8 immersed, which is filled with washing water from the washing trough 14.
- the Wash water has a favorable pH of about 11 or higher and contains Remains of dye and excipients such as alkali and reducing agent. Through this Characteristics of the wash water, the oxygen is largely to completely removed from the threads 4, and these take up a part of the dye. To this Way must dosed much less dye and excipients in the dyeing trough 6 become.
- the threads are guided over the second guide rollers 11 so that they have sufficient contact time for mass transfer with the dyeing liquor.
- the Dyeing liquor will be the required amounts of water, dye and excipients dosed.
- the threads are 4 in the second Crushing 7 pressed again.
- the squeezing pressures in the first and in the second squeezing 10, 7 the same size, so that the threads 4 in the inlet of the Därbetrogs 6 have the same humidity as in its outlet and a dilution of the dyeing liquor is prevented.
- the entire area from the first to the second squeezer 7, 10 is below the Hood 13 provided with an inert atmosphere.
- the device for dyeing the air under the hood 13 replaced by nitrogen, the e.g. is supplied from a compressed gas cylinder via the associated line. While Normal operation is no or only occasional replenishment of nitrogen required.
- the threads are washed in the washing trough 14.
- they are alternately immersed in the washing trough 14 several times in succession and squeezed in the third Quetatken 16. This will be excess Dye and excipients from the threads 4 removed.
- the threads 4 are dried and further processed, e.g. wound.
- other textiles such as e.g. a web treatable.
