Definitions

  • the present invention relates to a process for the continuous dyeing of strand-like textile material made of synthetic and / or natural fibers with aqueous liquors - containing dyes suitable for the fiber type in question on jet (dyeing) machines, the feed for the transport of the goods through them closed treatment zone takes place essentially via the actuation of the nozzle system by means of the kinetic energy of a circulated gas stream.
  • the main feature of this working technique is therefore that the goods are conveyed through the unit in a continuous, continuous form due to the kinetic energy imparted by the tangential application of the jet, whereby according to the process control explained for the drive of the strand during the different treatment stages gas and liquid flow can alternate or be combined, which allows a seamless transition from one dyeing step to another without a standstill and under isothermal conditions.
  • the fiber material is introduced in batches into the dyeing jet and is charged there with the liquor in such a way that it is injected in atomized form into the circulated gas stream, whereby the textile goods and the treatment fleet not taken up by him are always recirculated.
  • the order of the entire fleet amount is distributed over several product circulations and through the continuous recirculation of the excess fleet an even spreading of the fleet on and in the strand is achieved and thus an excellent level of treatment result.
  • the material dyed in one piece is removed from the jet.
  • US Pat. No. 3,330,134 describes a process for the liquid treatment of textile goods in a relatively long liquor without intermediate drainage, the movement of the textile goods taking place exclusively with pressurized water from nozzles, and this movement being supported by driven rollers.
  • a tunneling of goods with hot air or steam is not mentioned. Since it is a hydraulic system, there is a long liquor ratio, so that a continuous dyeing process cannot be carried out economically with this method.
  • DE-A-2 358 712 discloses a method and an apparatus for treating textile materials, the term treatment comprising any processing of textile materials in a wet or dry atmosphere, for example degreasing, impregnating, steaming or drying the goods.
  • the material to be treated is passed through successive treatment zones without tension in the up and down flow by means of a liquid medium, for example a liquid metal or a molten salt, the liquid medium separating the successive treatment zones from one another.
  • a liquid medium for example a liquid metal or a molten salt
  • the machine to be used can be kept relatively simple, because it does not need to be divided into application and separate fixing areas, because only one in the The application area integrated or located directly in front of it guarantees the occupational safety and time reduction aimed for by the method.
  • the object on which the invention in question was based was therefore to design the application conditions for the colorant in such a way that, with as few as possible, if possible, minimal liquor application, uniform coloring was achieved in a fully continuous manner, if possible under isothermal conditions.
  • Another object of the invention was to design a machine suitable for carrying out such a project.
  • the object outlined above is achieved according to the invention by continuously introducing the long-running textile strand into the treatment zone, possibly via an element which seals the outside atmosphere, impregnating it there with the dyeing liquor during its further passage and then using an aerodynamically effective arrangement arranged in the direction of movement of the goods Nozzle arrangement, consisting of at least one transport nozzle, is conveyed forward through the treatment zone at such a speed that it is subjected to a dwelling operation therein, optionally under fixing conditions for the dye or mixture thereof, after which the textile strand treated in this way is optionally removed via a further sealing element of the same type as at the beginning - continuously removes the treatment zone.
  • the claimed method is usually carried out as follows: To apply the intended colorant to the goods, the textile material is first subjected to the measures for impregnation, which is sewn together to form an endless, not self-contained strand, which can expediently already happen during the introduction of the strand into the treatment zone or immediately thereafter, and then it becomes fed to a first nozzle in which the goods are brought to the intended treatment temperature by means of hot air or a steam / air mixture. At the same time, the gas flow takes over the further transport of the goods strand due to its inherent kinetic energy imparted by a blower.
  • the impregnated goods are expediently turned into a second Nozzle supplied and through this - and in the same way via possibly necessary further nozzles and further induction loops - transported through the treatment chamber.
  • the impregnation and the residence are preferably carried out under isothermal conditions.
  • the dyeing liquor can be applied to the continuously arriving textile goods in various ways:
  • an impregnation device can be used, which consists of a relatively small trough in which at least one perforated drum, loaded with liquor from the inside, runs. Between the trough wall and the rotating perforated drum, the strand of goods is partly wrapped over the lateral surface of the latter and then impregnated during the passage.
  • the textile goods are also impregnated if the fabric strand is passed through a single or a series of annular nozzles arranged in the direction of travel of the goods and fed with the dyeing liquor.
  • the dyeing liquors are added to the circulated gas stream practically in the area of the nozzle arrangement for the advance of the goods by injection in atomized form, as already described in EP-PS 0 078 022 .
  • the same result is further achieved by metering the dyeing liquor into the gas stream driving the fabric strand on the suction side of the blower producing it, the latter causing its fine distribution by atomization into the flowing gas.
  • the dyeing liquors to be applied generally contain all the necessary treatment agents, such as, for example, dyes, fixing chemicals, pH regulators, other auxiliaries, such as, if necessary, carriers or wrinkle inhibitors. If their stability requires it, they can only be mixed together by suitable dosing devices immediately before entering the dyeing machine. In order to achieve a good impregnation of the textile, the liquor can furthermore have wetting agents and substances which promote the uniform liquor distribution during the subsequent fixing process.
  • the amount of liquor used according to the invention is preferably dimensioned such that the entire applied liquor remains in the strand of goods and no excess migrating liquor occurs during the subsequent fixation, since otherwise it drips off the strand of goods after dripping and is fed to the previous impregnation step in the circuit would have to be in order to come into action again and again in the course of treatment.
  • the textile goods can be transported further after the dye liquor has been applied:
  • the line of goods can be moved in the course of crossing the treatment zone, for example as a loop by means of spiral-shaped nozzles in the manner of the clapot, such nozzles optionally being operated with steam, hot air or a steam / air mixture.
  • the textile material can also be conveyed in a spiral-like manner purely mechanically via a driven reel or a plurality of separate reels. It is also possible to place the textile goods on a conveyor belt or a floor conveyor and thus expose them to the effects of the fixing atmosphere.

If the claimed process is carried out at atmospheric pressure, the latter are below 100 ° C, preferably in the range between 10 ° and 100 ° C; if working under increased pressure, in the range between 100 ° and 150 ° C.
  • a particular embodiment of the method in question is given if it is carried out under the conditions as described in European Patent EP-B-0 087 740.
