Definitions

  • the invention relates to a method for treating a material web, in particular a fabric web according to the preamble of claim 1. Such treatment methods are used above all for washing fabric webs in order to remove residues of dyes, sizing agents and other treatment agents. The method could also be used for purposes other than cleaning the material web, e.g. for impregnation or the like.
  • the invention also relates to a device suitable for carrying out the method.
  • the web is conveyed through two communicating chambers, the aim being to achieve a high flow rate in the chambers by drawing in liquor from a chamber by means of a pump and in the another chamber is introduced at high speed via a tangential nozzle.
  • SU-A 1145063 describes a method for washing a continuously moving textile web, in which the textile web is passed through narrow chambers.
  • the width of the chambers is between 3 to 20mm.
  • Nozzles are arranged in the chambers, from which a washing liquid is applied to the textile web under turbulent flow.
  • the concentration of the wash liquor to be disposed of should be as high as possible so that the substances contained therein can also be recovered if necessary.
  • this object is achieved by a method which has the features in claim 1.
  • the narrow shaft practically forms a nozzle in which the treatment medium can act intensively and for a sufficiently long period of time on the material web. Maintaining an overpressure relative to atmospheric pressure causes a turbulent flow of relatively high speed in one direction of the shaft.
  • the use of a vaporous or gaseous treatment medium has the advantage that the use of liquid treatment medium can be kept as small as possible.
  • the substances detached from the material web by the steam accumulate in high concentration in the liquid component, while the steam can be easily sucked off and fed in again after a preparation process.
  • the material web can also be supplied with a liquid treatment medium from a separate nozzle arrangement. It is also conceivable to use saturated water vapor and / or air and washing liquor, each medium being introduced into the chamber from a separate nozzle arrangement or applied to the material web.
  • a washing liquor applied to the material web can subsequently be discharged again, for example, or partially evaporated through a gaseous medium, so that no special squeeze rollers are required to squeeze out the washing water.
  • the treatment media are preferably applied on both sides of the material web and / or one behind the other in the direction of movement. However, it would also be conceivable to apply the material web only on one side, or to introduce different treatment media on different sides or at different points in the shaft.
  • a rising and a descending run of the material web is particularly advantageously passed through a separate shaft, the treatment medium being applied to both shafts at the upper end and the two shafts communicating with one another at the upper end and the treatment medium being discharged at the lower end of the two shafts become.
  • the material web can also pass through several, for example vertical, shafts which are arranged next to one another or one above the other and in which treatment medium is applied at the upper end and in which the treatment medium is discharged at the lower end.
  • the liquid component of the Treatment media are collected in a tub, which can also be designed as an immersion bath.
  • the liquid could also be removed directly from the shaft.
  • the liquid collected on a shaft is particularly advantageously fed in countercurrent to the nozzle arrangement of an upstream shaft. This countercurrent principle is mainly used for washing, with increasingly pure washing water being applied with increasing cleaning stages.
  • the liquid treatment medium of the last treatment zone can be fresh water.
  • the pressure and / or the amount of the treatment media supplied can preferably be controlled separately for each medium. Depending on the nature of the material web, different conditions can be achieved in the treatment zones.
  • the method can be carried out particularly simply and advantageously with a device which has the features of claim 9.
  • the shaft can be loaded with any liquid, gaseous or, under certain circumstances, even solid treatment media in the form of a granulate. So it would be e.g. it is conceivable to apply a free-flowing sand to the material web in order to achieve a certain surface effect. A subsequent air nozzle could in turn blow away any sand particles still adhering to it.
  • At least three nozzle arrangements in the form of separate collector tubes are connected to one another. In this way, several different treatment media can be used in succession, but it is also possible, if necessary, to switch off individual collector tubes. This makes it possible for the device to be used for very different purposes without expensive conversion work Purposes can be used.
  • Opposing nozzle arrangements are preferably present on both sides of the material web. A deflection of the material web as a result of the pressurization can thus be prevented since the pressure of the media flowing against one another cancel each other out.
  • the distance between the material web and the nozzle arrangement is preferably adjustable. In this way it can be achieved that the material web runs through a narrow slot in the treatment zone without any friction points.
  • the collector tubes used as a nozzle arrangement preferably have a rectangular cross section, since these tubes can be connected to a unit in a particularly advantageous manner.
  • the interconnected collector tubes preferably form a gas-tight wall section of the treatment zone, which can be removed and / or moved. This design has the advantage over the known treatment zones that a gas-tight chamber does not have to be built around the nozzle arrangements.
  • the connections for the collector tubes are directly accessible from the outside, so that no additional bushings or seals are required.
  • the collector tubes or the treatment zones can be arranged at any relative position of the material web.
  • several vertical shafts are preferably arranged next to one another, a separate chamber being provided below each shaft.
  • at least one chamber can be connected to the suction line of a pump, the pressure line of which leads to a collector tube which is assigned to an upstream shaft.
  • the collector tubes can have nozzles whose flow axes or planes to the passage plane of the material web are inclined.
  • the axes or planes can also be arranged at right angles to the material web.
  • the axes or planes of adjacent collector tubes intersect, the point of intersection being in front of, on or behind the material web.
  • each shaft has hollow side walls in cross section and in that a heating medium can be conducted through the side walls.
  • the side walls can be formed by horizontally stacked hollow box profiles, the ends of which are closed at the end and which are connected to one another by openings. This creates a particularly stable and torsion-resistant shaft construction.
  • the heating of the cavity walls causes the outside of the wall construction to have approximately the same temperature as the inside facing the textile web. This excludes temperature-related changes in position.
  • the heating of the side walls ensures that the vaporous treatment medium does not condense out too quickly.
  • the collector tubes used as nozzle arrangements can be formed by the same hollow box profiles as the side walls.
  • the side walls thus form a compact unit in which the nozzle arrangements are integrated.
  • the gap width of each shaft is preferably adjustable by means of an adjusting device, so that the optimal gap width can be selected in individual cases.
  • FIG. 1 shows a high-performance washing compartment 1, which is constructed on the principle of a so-called roller skid and which has an upper roller 2 and two lower rollers 3a and 3b.
  • the latter are stored in a trough 4, which can be designed with or without subdivision 5, depending on the intended use of the washing compartment, or which is fed with or without countercurrent flow.
  • the trough 4 has e.g. an outlet 6 for emptying the chamber 7 and a pump connection 8 for the supply or discharge of washing liquor. If a counterflow is provided, the wash liquor is fed through the counterflow inlet 9 and discharged through the counterflow outlet 10.
  • the trough 4 is largely sealed against the escape of steam by cover plates 11 or by the cover 12, the fabric web 15 being immersed in the trough 4 via an inlet opening 13 and being withdrawn from the trough via an outlet opening 14.
  • the fabric outlet opening 14 is of course connected in a shaft-like manner with the fabric inlet opening 13 of the subsequent washing compartment, so that steam losses are largely avoided. (See e.g. Fig. 6).
  • the two shafts 16 and 17 are arranged, so that the ascending and descending strands of the fabric web guided over the top roller 2 each run into a separate shaft.
  • outside side covers 18 are provided which facilitate the pulling in of the fabric web 15 and which allow the material web to be observed.

  • the tubes could possibly also be of exactly square design.
  • the tubes are welded to one another in a gas-tight manner, a fastening strip 27 or 28 being welded to the uppermost tube 33 and the lowest tube 35.
  • the individual collectors are thus designed directly as a gas-tight wall section of the shaft.
  • the collectors also each form a connecting wall between the shafts 16 and 17 and the upper part 19. In order to enable the collectors to be moved laterally in the simplest way, intermediate pieces 22 and 23 are installed.
  • a side wall 56a or 56b is provided, which is pressed sealingly against the collectors.
  • This side wall could possibly also seal the individual collector tubes directly to the side.

However, it would also be conceivable for the individual collector tubes to be connected to one another in such a way that the nozzles of the individual tubes are at different distances from the fabric web. Finally, it would even be conceivable that the nozzle cross section can be changed from the outside with a slide or the like, or that individual nozzle openings can be completely covered in the same way.

  • the distance could also be be larger and be up to 40 mm. So that the fabric web 15 is not damaged by the very close collector tubes 33 to 35, these are provided with relatively large rounding radii at the corners. These also allow a recessed welding, whereby no protruding weld seams are formed.
