Definitions

  • the invention relates to a method and a device for treatment, in particular for dyeing fabric warp threads, in which the warp threads pass through a so-called sizing bath in the raw (white) state, which stiffens the warp threads and makes them more wear-resistant, whereupon the warp threads treated in this way are woven and that textile produced in this way is dyed.
  • a disadvantage of this known method is that due to the later dyeing of the warp threads after the fabric has been made at the white weaving mill, the time required for the manufacture of the finished product is relatively large, since separate operations accrued, which are connected with intermediate storage, intermediate drying and the like, which leads to an increase in the cost of the production of such fabrics.
  • the invention is accordingly based on the object of providing a method and a device with which it is possible to drastically reduce these costs.
  • untreated warp threads in the raw (white) state pass through at least one bath containing the size composition in a single operation in a continuous process, wherein in addition to the size in the bath, the colors to be applied in the form of viscous material or in pasty form Condition.
  • At least one trough is expediently provided, which receives the bath containing the sizing materials and the viscous paint and through which the warp threads to be treated are guided by means of roller transport.
  • a trough for the size and a trough for the color may be arranged immediately one behind the other, but the size and color are likewise applied in one pass in a single operation.
  • the trough or the troughs are arranged directly in front of a drying chamber in which the warp threads provided with size and color are subjected to drying.
  • This arrangement creates the possibility, after the actual drying chamber, of further treating the dyed warp threads, in particular printing and coating, in the form of wet-on-wet processing, which is only feasible for paints or coatings in the form of dispersion coatings.
  • the arrangement according to the invention also creates the possibility, immediately after the actual drying chamber, to provide a further printing device with which the warp threads can be coated with paint, varnish and dispersions or the like after the drying process.
  • the printing device can contain an ink receiving box, from which the surfaces of printing rollers are provided with ink.
  • the pressure rollers can be pressed against a support surface with the interposition of the warp threads, whereby this support surface can be a bottom roller.
  • this support surface can be a bottom roller.
  • the emulsion contained in a storage container and which is made of size and color and which can be transferred into the troughs or troughs is kept in a flowable state, for which purpose at least one stirrer is expediently provided, which intervenes in the mass.
  • at least one stirrer is expediently provided, which intervenes in the mass. The same applies to the paint containers.
  • the agitators can be set so that not the entire mass is stirred, but that only a partial stirring takes place, so that marbling veins or traces are formed which are transferred to the warp threads.
  • there are corresponding patterns on the finished textiles which can be further influenced by the fact that the finished dyed warp threads are subsequently treated by brushing or the like in a manner known per se.
  • the respective color can be supplied to the troughs from color magazines, which are provided with a return line with a pump, in order to return unused color contained in the troughs to the color magazines, so that it is possible to use up the color almost completely.
  • the excess colors still contained in the warp threads can be squeezed out laterally and reach neighboring regions, so that the color patterns are further influenced.
  • Brushing can take place both in front of and behind the drying chamber, but only in front of the drying chamber if it has been colored beforehand.
  • At least one color magazine can be connected to the feed lines for the size materials, in which thickened color pigment doughs are controllably supplied to the size material.
  • the color formulations can be chosen so that the desired amounts of color are drawn in at the same time or partially or completely adhere to the warp threads, although the sizes are applied at full production speed - as explained above.
  • the recipes can be controlled in such a way that you can choose between color surpluses and color shortages. Excess color can e.g. serve that after a special desizing process the weft threads are already colored.
  • the closed color cycles ensure that the material used is almost completely used up and that there are no additional disposal parts in the production process.
  • wet-on-wet printing can achieve color printing or color structure effects through synchronously running ink or application units on the warp yarns, which can be dried in the drying chamber controlled by means of a moisture measurement.
  • additional yarn changes and effects can be achieved through the action of additional sponge, smooth and brush rollers that move along.
  • the warp yarn arriving in a sorted manner can be processed immediately after it leaves the drying chamber via a further synchronously running inking or application unit. Since all warp threads are already sorted at this point and above Exiting hot, the entire warp set can be printed, coated or processed with any motif. Printing or coating these hot warp threads creates a new type of reaction between the printing and coating material and the warp threads.
  • the warp threads run through the device in the direction of arrow 1, that is to say from left to right in the representation there.
  • the warp threads which have not yet been treated, are wound on bobbins or the like 2 and pass through separating and sorting devices 3. Subsequently, a drying chamber 6 is provided, the housing of which is designated 5, the housing 5 already saving the device part according to FIG. 2 includes, in which, in the illustrated embodiment, two troughs 6 arranged one behind the other are provided for coating in the manner described. This part of the device is designated 7 (see also FIG. 2).
  • warp threads are already separated into upper and lower threads in the vestibule 8 containing the bobbin 2, it is possible, as shown in FIG. 1, to assign different troughs 6 to the warp threads, which then also have different sizing materials, but in particular different color materials can be filled.
  • first the lower threads 10 and then the upper threads 9 are coated.
  • the warp threads coated and dyed in this way pass through rollers 11 and 12, which can preferably be heated, into the actual drying room 4, where their drying is completed. Since the drying room 4, like the rooms 13 and 14 provided with heating rollers, is subject to the same air heating (a temperature of approximately 140 ° C. being generated in the drying room, that is to say inside the housing 5), pre-drying takes place in the rooms 13 and 14 , which is completed in room 4, so that the dried threads emerge hot in the direction of arrow 15 from the drying chamber.
  • the coated and dyed warp threads leave this space in the direction of the arrow 18, being separated according to the upper and lower threads in order to be wound up on a warp beam 19 or the like.
  • the warp beam 19 rotates in the direction of the arrow 20.
  • the drying chamber 5 is provided with an air heater 21, the radiator of which is designated 22.
  • the pipe system of the heater 21 is provided with hot or warm air outlet nozzles 23 and 24, through which the heated air is supplied as room 17 and rooms 25 and 26 is, with the predrying rooms 13 and 14 also being heated via the latter.
  • the device parts shown in FIG. 2 are contained in rooms 25 and 26, which have a trough 6 containing a mixture or an emulsion of the sizing materials and the viscous colors, through which the warp threads 9 and 10 by means of rollers 27 and 28 (see also FIG. 2) are performed.
  • the trough 6 is connected via a line system 29 to the outlets 30 of individual paint containers 31 and 32, the outlets 30 being closable by valves 33.
  • Via a return line 34 which is acted upon by at least one pump 35, unused material is fed back to the ink containers 32, until the ink is used up.
  • the individual paint containers 31, 32 are provided with agitators 36 which keep the viscous or pasty paint in the paint containers 32 in a flowable state.
  • a larger container 37 contains a stock of sizing material, this container also being provided with an agitator 38, the drive motor of which is designated 39, as are the motors of the agitators 36 according to FIG. 2.
  • the size container 37 also has an outlet connection 40 with a shut-off valve 41, which is arranged in a line 42 which leads to a pump 43 with which the size composition is pumped upwards in the direction of arrow 54 into the trough 6.
  • the container 37 is connected to the outlets 30 of the paint containers 32 via a connecting line 44, this line also having a shut-off valve 45.
  • the ink contained in the ink containers 32 can be introduced into the sizing agent container 37 in different amounts, in different compositions and, if appropriate, also in different consistency.
  • FIG. 3 shows that part of the device that belongs in the space 17 according to FIG. 1 and serves to a certain extent for the post-processing of the treated warp threads.
  • additional imprints can be applied in this aftertreatment part in the wet process, which can be done by synchronously running ink or application units 46.
  • smoothing rollers 47, sponge rollers 48 and brush rollers 49 can also run in order to achieve further yarn changes and effects.
  • the ink masses to be applied via a feed system 50 are only applied to the surfaces of the rollers from above applied by means of feed pipe 51; a bath treatment as in the section described above is not an option for this post-treatment.
  • the warp threads 9 and 10 are so hot that the entire warp set can be printed, coated or processed with motifs of any kind.
  • color can be applied via a further synchronously running inking or application unit 52 (see FIG. 1) and at the same time dried by contact with the hot warp threads.
  • the printing or coating of these hot warp threads creates a new type of reaction between the printing and coating material and the warp threads.
