Definitions

  • the invention relates to a method (according to the preamble of claim 1) and a device (according to the preamble of claim 3) for the continuous wet-on-wet treatment of a web.
  • a wet-on-wet treatment is understood to mean a continuous process in which a web of material, for example a textile web, in cut form, in the strand or as a tube passes through at least two baths or impregnation chassis.
  • the web is drained as much as possible after a first wet treatment. After dewatering, the material web passes through a diving trough, an impregnation chassis or another wetting device, is wetted or soaked with the appropriate liquor and then brought back (with squeezing units or by suction) to a certain residual moisture, which in this case must be higher than the moisture when entering the wetting device.
  • the Inlet moisture can be, for example, 100% and the outlet moisture can be 130%.
  • the differential humidity (thus 30% in the assumed example) must be introduced into the treatment bath by post-dosing, and all the chemicals and preparations required for the desired treatment process must also be contained in this post-dosing.
  • the first method uses computers or manual devices that record the weight of the goods and the machine speed and accordingly regulate the dosing. In view of the constantly changing widths of goods and the differences in the composition and weight of each type of goods, this process is very complex and difficult to control.
  • the second method works on the principle of carry-over. A fleet level that is as constant as possible is thus maintained and the addition metering is controlled accordingly. However, there are two conflicting requirements with this method that are difficult to reconcile.
  • the smallest possible amount of liquor i.e. a small chassis content
  • the incoming goods bring with them, for example, 100% water (residual moisture) and undissolved preparations, some of which dissolve and mix in the bathroom; At the same time, 130% is carried out in the assumed example.
  • the 30% differential humidity is then adjusted using a level control and contains all the chemicals and preparations required for this process. It is obvious that in this case a small amount of the fleet, i.e. H.
  • a low chassis content is a great advantage, because after a short time an equilibrium is established (because the outgoing goods also carry off detaching dirt and water).
  • the batch dosing has been carried out intermittently so far that the batch dosing is switched off when the target level is reached and is switched on again when the target level is undershot.
  • Uniform treatment, for example impregnation, of the material web is not possible in this way.
  • EP-A-87 391 discloses a method which corresponds to the preamble of claim 1 (and a device which corresponds to the preamble of claim 3), in which a web of material to be treated is fed through at least two partial baths, each with an output squeezer and assigned level controllers, wherein the first partial bath is preferably smaller than the second and a desired application of chemicals is to be achieved quantitatively essentially already in the first bath, while the second bath then essentially only ensures a uniform distribution of the chemicals.
  • the concentration of the chemicals in the bath is monitored over a certain period of time by means of analyzers, then the concentration required for the desired chemical application is determined from the speed of the change in concentration, and the concentration of the chemicals is then corrected accordingly.
  • all baths can be equipped with separate or shared analyzing devices and a similar computer; the analyzing devices are connected to the circulating circuits of the baths and are connected to the computer, from which both a metering device connected to the liquor circuit of the first sub-bath and a meter leading directly into the second bath Dosing device of the chemical storage container can be controlled.
  • the bath level in the two sub-baths is regulated separately using assigned level probes and level controllers, which are connected to a separate fleet reservoir for control purposes.
  • the invention has for its object to provide a method according to the preamble of claim 1 and a device according to the preamble of claim 3 so that the bath concentration is kept constant with high accuracy and the equilibrium is reached quickly.
  • the method according to the invention thus combines the advantages of a small amount of liquor, ie. H. a low chassis content, with the advantages of a constantly regulating addition dosage.
  • the equilibrium state is reached quickly at the beginning of a treatment process, and there is only a small amount of waste liquor with process changes.
  • the continuously regulating batching ensures that a constant bath concentration and thus an excellent quality, in particular uniformity, of the wet-on-wet treatment is maintained.
  • the device shown for the continuous wet-on-wet treatment of a web 1 contains a first treatment bath 2 and a second treatment bath 3, which are passed through by the web 1 in succession. After passing through the treatment bath 2, the web 1 is brought to a certain residual moisture (for example 100%) by squeeze rollers 4, which at the same time the inlet moisture FE of the web upon entry represents in the treatment bath 3.
  • a certain residual moisture for example 100%
  • the material web 1 leaving the treatment bath 3 is brought to a certain residual moisture (for example 130%) by squeeze rollers 5, which thus represents the outlet moisture FA (based on the treatment bath 3).
  • the treatment bath 3 is filled with liquor 6, the level of which is monitored by a float 7 of relatively large volume.
  • This float 7 compensates for mechanical resistance and foam formation and actuates a potentiometer 8, which is connected to a device 9 for comparing the setpoint and actual value.
  • a controllable motor valve 10 is connected to the device 9, through which the amount of fresh water to be added (arrow 11) is metered.
  • the amount of water flowing through the engine valve 10 is measured by a water meter 12 to which a microprocessor 13 is connected.
  • This microprocessor 13 determines the amount of additives (chemicals, preparations, etc.) to be added to the respective amount of water.
  • a number of metering pumps 14, 15, 16 are connected to the microprocessor 13, which introduce the required amounts of additives from storage containers 17, 18, 19 into the water line 20, which leads to a nozzle 21 which the subsequent dosing takes place.
  • a factor f is taken into account in the microprocessor 13, which is formed by the quotient of outlet moisture FA and differential moisture (FA-FE).
  • the content of the treatment bath is expediently dimensioned so small that a complete liquor exchange in the treatment bath takes place within 5 to 20 minutes, preferably within 10 to 15 minutes, as a result of the addition metering.
  • the chassis content should not exceed 50 to 75 l.
