Definitions

  • the invention relates to a method and a device for mercerizing a fabric web according to the preamble of claim 1 and of claim 5.
  • the fabric web is sprayed in the spreader zone using hot weak lye or hot steam. This reduces shrinkage forces and stabilizes the fabric web. The stretching itself partially compensates for the shrinkage caused by the impregnation process.
  • a method of comparable generic type has become known, for example, from the applicant's EP-A-0 198 793.
  • the warp thread spacing should be uniform over the entire width of the fabric web, so that the fabric has the same density everywhere.
  • This object is achieved by a method which has the features in claim 1. This measure initially only stabilizes the edge zone, but not the central zone of the fabric web. The consequence of this is that the spreading forces caused by the tensioning chains are transferred from the already stabilized edge zones to the middle zone, which has not yet been stabilized or has not been stabilized yet. This results in an approximately uniform stretching force over the entire width of the textile web, so that the warp threads in the middle zone are also pulled apart.
  • the stretching forces are not exhausted in the marginal zone by giving in, as this is prevented by the targeted stabilization.
  • the spray density advantageously decreases approximately evenly from the edge zones towards the central zone of the fabric web, since the stretching forces also reduce towards the center of the fabric web.
  • the edge zone is at least 10% of the fabric width and at most 40% of the fabric width. At least twice the amount of the hot medium is sprayed onto the edge zone.
  • the spray nozzles can be arranged on a pair of spray tubes which is arranged at the desired angle and at the desired distance from the outer edges of the fabric web above the conical inlet field of the tenter frame.
  • the pairs of spray tubes are preferably at the same angle as the conical one Inlet field arranged so that the edge zones are sprayed evenly in the course of the feed of the fabric web.
  • the spray tubes can also have a slightly different angle relative to the outer edge of the fabric web in the conical inlet field of the tenter frame.
  • a particularly simple construction results if the spray nozzles are designed with respect to their arrangement and / or opening cross section such that the amount of the sprayed medium decreases towards the central zone of the fabric web. In this way, a single spray tube over both edge zones is sufficient to achieve the desired effect.
  • the tensioning frame advantageously has an adjusting device for changing the distance between the two tensioning chains, the spray tubes being fastened to the tensioning frame in such a way that they can be adjusted together with the tensioning chains.
  • the spray pipes above the two edge zones are always approximately the same distance from the outer edge of the fabric web.
  • the adjustment device can also be designed such that when the tension chains are adjusted, the spray tubes travel a proportionally shorter distance.
  • a plurality of parallel spray tubes are arranged above each edge zone and can be controlled individually via control valves.
  • These Spray tubes can be arranged so that only the tension chains need to be adjusted for a different width of fabric.
  • the spray density can be pre-selected by setting the control valves accordingly.
  • Individual spray pipes can be switched off completely or only partially fed with the hot medium.
  • the edge zones are preferably about 30% of the set web width, but at least 10% and not more than 40%.
  • spray tubes extending across the side-parallel field of the tenter frame can be arranged, which are provided with spray nozzles evenly distributed over the entire width of the fabric web.
  • the side-parallel field of the stenter connects directly to the conical inlet field with the spray pipes above the edge zones.
  • the spray tubes which are arranged transversely to the fabric web, spray the stretched fabric web evenly over the entire width and thus bring about a final stabilization.
  • FIGS. 1a and 1b show the disadvantages already mentioned in the introduction in a spreader method according to the prior art.
  • the warp threads 1 in the two edge zones 14 and 14 ' have a greater distance b than the distance a in the central zone 19. This phenomenon occurs in known chain tensioning fields without controlled stabilization of the fabric web. The spreading forces act almost exclusively on the two peripheral zones, while the central zone 19 remains unchanged.
  • FIG. 1b In the case of spreading by means of specially designed stabilizing or spreading rollers, an opposite but equally undesirable effect occurs, as shown in FIG. 1b.
  • the spreading effect decreases from the center towards the outside, so that the distance a between the warp threads in the edge zones is smaller than the distance b in the middle zone 19. It is obvious that a mercerized fabric web with a structure according to one of the figures 1a or 1b does not correspond to the desired quality.
  • FIG. 1c shows the structure of the fabric web, which is aimed at and also achieved with the method according to the invention, in which the warp threads 1 have a uniform distance c both in the central zone 19 and in the edge zones 14 and 14 '. This uniform distance is achieved by locally differentiated control of the stabilization process, so that the spreading forces can extend uniformly from the outside over the entire width of the fabric web.
  • a mercerizing machine 3 consists of various processing sections which are continuously traversed by the endless fabric web.
  • the fabric web 2 is introduced in an insertion zone 4 into the impregnation zone 5, where the impregnation takes place in a bound web guide in a hot-water bath.
  • the impregnation zone is followed by a cooling zone 6 and a dwell zone 7.
  • the width of the fabric web 2 continuously decreases in these last two zones due to shrinkage.
  • the fabric web must therefore be stretched again in the spreading zone 8 in the most gentle manner possible.
  • This is followed by the stabilization and leaching zone 9, where the mercerization process is completed.
  • the fabric web 2 treated in this way is then fed to an aftertreatment machine 10. Details of such a mercerization process can be found, for example, in EP-A-198 793 mentioned at the beginning.
  • a tensioning frame 11 is arranged in the spreading zone 8 and is provided with a pair of tensioning chains 12. These tension chains grip the fabric edges in a manner known per se by means of needle bars and / or clamps and stretch them in the conical entry field of the tension frame, where the distance between the two tension chains increases. Then the fabric web is stretched over a certain length in a section parallel to the sides by the tension chains Kept at a distance. It was already known to spray hot weak liquor onto the fabric web over the tenter frame 11 and in particular also over the conical inlet field from spray nozzles. This reduces the shrinkage forces gently and stabilizes the stretched fabric web.
  • the spraying with hot weak liquor or with another hot medium is now carried out in such a way that the edge zones 14, 14 'are sprayed more intensively than the central zone 19 in the conical inlet field are arranged at the same angle as the inlet field.
  • spray tubes there are spray nozzles, not shown in more detail, e.g. arranged in the form of simple bores which achieve a spray density that decreases from the outside inwards, as shown in FIG. So that the spray tubes 13, 13 'adapt to different fabric web widths, the spray tubes are attached to the tenter frame 11 such that they can be adjusted in width together with the tension chains 12.
  • An adjusting device 18 is shown symbolically in FIG.
  • the spray tubes 13 and the tension chains 12 can be adjusted via a spindle with the aid of a motor M.
  • the spindle has opposite thread sections so that the nuts sitting on it move towards or away from each other when the spindle is turned.
  • Both spray tubes are fed via a common manifold 17.
  • these are connected to the manifold, for example, via a flexible hose.
  • transverse spray tubes 15 are arranged, via which a uniform spraying with lye takes place after the completed stretching process.
  • a plurality of parallel spray tubes 13 are fixedly arranged over both edge zones 14, 14 '. These are also fed via a common manifold 17.
  • a valve 16 is arranged between the manifold and each individual spray tube, so that individual spray tubes can be switched off or on depending on the width of the fabric web to be treated.
  • the quantity of the medium to be sprayed via each individual spray tube can also be controlled via the valves 16.
  • transverse spray pipes can also be fastened over the conical inlet field of the tenter frame, similar to the spray pipes 15 over the side-parallel section. By drilling these pipes, the frequency of which decreases from the outside inwards, more intensive spraying of the edge zones could also be achieved.
  • FIG. 6 An example of a quantity distribution of the sprayed-on weak liquor is shown in FIG. 6.
  • the amount of alkali is entered above the ordinate 0 and the width of the fabric web above the abscissa A.
  • the edge zones R amount to approximately 30% of the total fabric web width. In the outermost areas about three times as much weak liquor is applied as in the central zone M.
  • the total amount i.e. the mean value of the amount of lye in the peripheral zone R is approximately twice as large as the lye portion applied in the central zone M.
