Definitions

  • the invention relates to a method and a device for applying liquor in a foamed form to a product comprising fibrous material according to the preamble of claim 1.
  • a method and a device of the type mentioned are known per se, namely from DE-OS 31 09 373 of the applicant.
  • an identical or related component of the liquor contained in the foam to be applied later is applied to the goods by a pre-order, the pre-order being intended for the subsequent dye application of foam to guide the way into the goods or into the fiber , so to ease into the material.
  • the pretreatment is carried out by wetting or soaking or soaking the goods, and wetting the goods or soaking or soaking can be done by washing, padding, dipping or spraying.
  • wetting the goods or soaking or soaking can be done by washing, padding, dipping or spraying.
  • all of the processes listed are unsuitable for pretreating the goods in such a way that they enter the subsequent printing and dyeing station with a low residual moisture value.
  • the criteria mentioned at the beginning which should be fulfilled, are not met. If the goods are soaked, they are too wet, just as if they were soaked by washing the goods.
  • the goods pass through a pair of rollers downstream of the soaking bath, the goods being squeezed off and consequently taking less liquor with them, but there is a difficulty in that uniformity over the total working width cannot be achieved. Even slight bending of the rollers means that the same edges and centers are not guaranteed.
  • the immersion of the goods for example by leading the goods through a jigger, does not produce the desired result, and spraying the goods cannot lead to uniformity either, since the spray nozzles with their spray cones have overlapping surfaces. Even if the spray nozzles are moved back and forth, it cannot be guaranteed that the goods are sprayed evenly with the pretreatment liquor.
  • the present invention is therefore based on the object to improve the method of the type mentioned so that the web or the goods inform of individual pieces of the subsequent foam application station for dyeing or printing is fed such that the subsequent application of the foamed liquor for dyeing or Printing takes place under optimal conditions because, on the one hand, an even distribution of the substances applied to the goods during the pretreatment is guaranteed and the residual moisture that remains on the goods should be kept within the lowest limits.
  • the invention is also based on the object of providing a device for carrying out the method according to the invention in which the pretreatment of the goods can be carried out using simple means.
  • the application takes place in the amounts of 10 to 100% of the weight of the goods, so that the conditions for taking up the dye-containing liquor in the subsequent foam application station are additionally influenced in a favorable manner.
  • two application units arranged one behind the other in the direction of travel of the goods are provided for the fleet, the front application unit being designed for applying the dye-free foam and the rear application unit for the dye-mixed foam .
  • the method according to the invention can be carried out without any special measure, since known work units can be used, as are known for screen printing. This even makes it possible to carry out the method according to the invention with existing devices.
  • the application unit at the front, as seen in the direction of flow of the goods, for applying the dye-free foam can be followed by one or more application units for applying the foam containing the dye.
  • the number depends on the number of colors to be printed.
  • the method according to the invention can be used both for a continuous and for an intermittent application method.
  • the dye-free foam is then also applied intermittently or continuously.
  • an applicator can be used in the known design.
  • this application unit can pressurize the foamed fleet in a closed application system with outlets directed towards the goods, with uniform pressure through the screen or the stencil.
  • the pretreated goods overflow a suction device after the pretreatment according to the invention, after which the foam is applied for printing or dyeing. Both are also possible, namely that the goods, preferably the web, first overflow the suction device and then enter the heat treatment or vice versa.
  • the applicator works similarly to a slot doctor blade, in that it is provided with outlets directed towards the goods, preferably an application slot, there is nevertheless the possibility of also using doctor blades or the like. to use.
  • goods of different types can be treated, but textiles of all types are preferred, e.g. Carpets, pile goods, velvet, fleeces, felts.
  • Non-woven fabrics, pullovers, sweater parts, T-shirts, garment parts or the like are unique items. conceivable, especially if they are placed in appropriate forms on the conveyor belt that leads the goods from the pretreatment station to the subsequent printing or dyeing station.
  • moisture-absorbing goods including paper and paper-like materials. These also contain fibrous material.
  • fibrous material In addition, it is not only possible to pre-treat flat goods, but also for example wise fibers, fiber strands and the like.
  • material webs includes thread webs, fiber strand webs and the like. not from.
  • the applied colorless foam is pressed through a sieve or through a stencil, the foam being destroyed and the resulting liquor being allocated to the goods exactly.
  • a material web 1 is drawn off from a supply roll 2 by a roller 3, which is not shown in more detail.
  • the roller 3 is driven by a drive 4 via two bevel gear drives 5 and 6 which are connected to one another in terms of transmission technology.
  • a deflecting roll 7 lying in the same plane as the roll 3.
  • a pressure blanket 8 which is also not explained in detail but is known per se. This runs around endlessly.
  • foam generators are also known as foam generators.
  • each application unit 9, 10 consists essentially of a screen 15, 16 and an application element 17, 18, which are shown as slot doctor blades in both exemplary embodiments.
  • the applicator units 9, 10 are also driven by the drive 4 via bevel gear transmissions 19, 20 which are technically connected to one another.
  • the first application unit 9, seen in the direction of flow is provided for the supply of dye-free foam, while the rear application unit 10 is intended to work with dye-added foam for carrying out coloring or, for example, printing.
  • Sieves or the stencils 15, 16 are designed as sieve or stencil cylinders in both exemplary embodiments and are likewise driven in a manner known per se. In any case, continuous operation is preferred. However, it is also possible to use screen template belts that are guided over rollers and are also known. The basic structure corresponds to known screen printing stations. If the screen cylinders are patterned, which is particularly suitable for the application unit 10, one speaks of stencil cylinders or stencil belts.
  • the present exemplary embodiments are designed for printing or dyeing, in particular, textile webs.
  • individual pieces can also be treated, as stated at the beginning.
  • the applicator units 9, 10 equipped with a slot doctor blade 17 or 18 other doctor blades can be used, for example roller doctor blades or the like.
  • Pretreatment is carried out by the same or related components, in such a way that in the pre-application a foam is also applied through a sieve or through a stencil.
  • related components with the same properties as are present in the foam which is used by the foam generator 14 of the printing and dyeing station 10, can also be used.
  • a suction device 22 is provided behind the application unit 9 below the web passage level, which is adjustable in relation to the application unit 9. This is provided with a suction slot 122, a flexible Suction line 222 and is connected to a suction pump 322.
  • a device for heat treatment 21 is preferably arranged downstream of this device.
  • this device for heat treatment is a damper.
  • a deflection roller 321 is located in the upper area of the damper. Saturated steam is used in the interior of the damper.
  • containers 421 are arranged in the input and output area of the damper, which are equipped with heaters 521 are provided. The material web runs in a U-shape around the deflection roller 321 and, after it has left the deflection roller 321, it runs into the printing and dyeing station, specifically into the application unit 10.
  • a different heat treatment can be used instead of a steamer, but other heat treatments are extremely problematic in terms of treatment uniformity.
  • the damper guarantees an even heat treatment across the entire working width.
  • the application unit 10 is also shown and described as a screen printing unit in connection with a foam generator and an application element 18, this being a preferred embodiment for achieving the foam application for dyeing or printing.
  • the subsequent foam application for dyeing or printing should also be controlled as precisely as the foam application for pretreatment. It would also be conceivable and possible for the application 10 to be designed differently than shown in the figures.
  • the foamed liquor is fed to the applicators 9 and 10 in a closed application system under pressure, the application elements 17, 18 being tubular and receiving the pressure build-up via lines 10, 11 from the foam generators 13, 14.
