Definitions
- the invention relates to a process for the continuous impregnation of, in particular wet, textile material in an impregnation compartment containing the impregnation liquor, through which the textile material is passed, the impregnation liquor as impregnation agent being a lye, in particular sodium hydroxide solution, or a lye, in particular sodium hydroxide solution, and additionally an oxidative agent contains active bleach, in particular hydrogen peroxide, part of the impregnating liquor being branched off, in particular continuously, via a bypass, filtered and fed to one or more sensors for determining the concentration of the impregnating agent.
- the branched-off part of the impregnation liquor is preferably also prepared in a defined manner before it is fed to the sensors.
- the concentrations are calculated and displayed.
- the values obtained can be used to control a metering unit for hydrogen peroxide and / or sodium hydroxide solution.
- the data can be saved on a personal computer and is available for printing.
- the invention is intended in particular for the continuous wet-on-wet impregnation which is very frequently used in the textile industry.
- the wet or moist textile material is continuously fed to the impregnation compartment. Since water is constantly being introduced into the impregnation compartment, the problem is to keep the concentration of the impregnating agent in the impregnation compartment constant.
- the concentration in the impregnation compartment can be changed from time to time, as is customary measure and replenish the impregnant accordingly.
- the necessary amount of impregnating agent to be metered in can also be determined on the basis of the weight of the goods introduced into the impregnating compartment.
- Dyer is a significant improvement in the previous practice of the textile industry, because it allows the concentration of the impregnating agent hydrogen peroxide in the impregnating compartment to be determined continuously and quickly, so that the required amount of impregnating agent can be replenished practically at the same time.
- a control loop can therefore be set up which constantly monitors the concentration in the impregnation compartment and adjusts it accordingly.
- the invention is therefore based on the object of achieving a continuous, trouble-free and precise replenishment of the impregnating agent, in particular sodium hydroxide solution or the combination of sodium hydroxide solution and hydrogen peroxide, in the process mentioned at the outset.
- the impregnating agent in particular sodium hydroxide solution or the combination of sodium hydroxide solution and hydrogen peroxide
- This object is achieved according to the invention in the method mentioned at the outset by heating the branched-off part of the impregnation liquor before the filtration.
- the heating prevents the starch constituents from coagulating in the impregnation liquor or the starch particles which have already been coagulated are dissolved again.
- the branched-off part of the impregnation liquor be heated to a temperature in the range from 30 to 60 ° C. and in particular to about 40 ° C. before the filtration.
- this temperature range has proven to be particularly advantageous for accurate and undisturbed determination of the concentration of the impregnating agent over a long period of time.
- amperometric and / or potentiometric methods be used to determine the concentration of the impregnating agent Sensors, dilutes the branched part of the impregnation liquor before the concentration determination, if necessary to adjust a pH value of about 7 according to the requirements of the hydrogen peroxide sensor, and galvanically separates it from the rest of the impregnation liquor.
- the sensors mentioned are known from the prior art and are commercially available.
- the dilution of the impregnation liquor is only necessary for the determination of hydrogen peroxide, since the corresponding sensor can only be used for concentrations of hydrogen peroxide which are significantly below the usual concentrations in the impregnation liquor.
- the galvanic isolation which can be done via a drip mechanism, is advantageous in order to obtain reliable results with certainty. In the case of the sensors mentioned, even a small fault current or a small fault voltage could lead to an error in determining the concentration.
- the signals from the sensors corresponding to the measured concentrations be fed to a control device for replenishing the impregnating agent.
- the concentration of the impregnating agent in the impregnating compartment usually changes.
- the change in concentration determined after 5 minutes can be used to calculate the concentration in the new equilibrium, since the difference in the equilibrium concentrations according to the findings and experiments according to the invention is approximately 8 times as great as the change in the concentration in the first 5 minutes.
- Constant textile qualities are achieved with the invention, since the concentration of the impregnating liquor can be kept practically constant, even if the textile material is changed.
- report logs can be created and printed out, or the stored data can be processed accordingly, so that, for example, the cause can be easily found out in the event of any errors that were only discovered later.
- the method can also be carried out with systems according to the prior art, since such systems can be easily upgraded.
- Figure 1 shows a system suitable for performing the method according to the invention or a corresponding flow diagram in a schematic representation without the lines and parts which are not essential to the invention.
- the method according to the invention can be subdivided into three main stages: First, the sample to be measured has to be taken and prepared. Then the measurement takes place. Thirdly, the fleet to be metered in is controlled with the measurement results obtained, so that a constant concentration of the respective impregnating agent is always maintained in the impregnating compartment.
- the liquor to be measured is led out of the impregnation compartment 1 via a bypass feed line 2 and heated in a heat exchanger 3 to a temperature of about 40 ° C. in order to prevent coagulation of the remaining constituents of the size agent within the subsequent membrane filters 4, 5. to which the heated sample is fed by means of a peristaltic pump 6.
- the unfiltered excess portion of the liquor is returned to the impregnation compartment 1 via a bypass return line 2a.
- the sample is cleaned of impurities> 0.2 ⁇ m. Contamination that remains in both filters is removed by cyclically rinsing the filter.
- water is fed into a heating device 30 via a service water connection 29, heated there to a temperature of about 60 ° C. and immediately transported into the two filters with the help of the peristaltic pump 6.
- the washed-out impurities are removed from the system via a channel connection 31.
- the filtrate from the first membrane filter 4 is used to determine the concentration of hydrogen peroxide.
- the filtrate flows through a level measuring container 7 to two dilution stations, between which a pressure compensation chamber 8 is arranged.
- Distilled water from a storage tank 9a is fed to the sample solution via line 10 and a buffer solution from a storage tank 9b via line 11, so that the sample is in the pH range suitable for the sensor and in the concentration range suitable for the sensor.
- hose pumps 12, 13 are also provided.
- the sample which has now been diluted twice, is now fed to the sensor 17 for hydrogen peroxide via a drip chamber 16, which is used for electrical isolation.
- the sample is then fed to a drip pan 28 for the waste solution by means of a hose pump 18.
- the sensor 17 is an amperometric molecular selective chemical sensor. It is commercially available from Zabs GmbH.
- the peroxide is continuously decomposed on a platinum electrode.
- the electrical current obtained represents the measured value, which is compared in a subsequent electronic device (not shown) with previously obtained calibration values.
- the filtrate from the second membrane filter 5 is fed to a sensor 21 for sodium ions and its reference system 22 via the first channel 19a of the peristaltic pump and a drip chamber 20, which is used for electrical isolation.
- Two storage tanks 24, 25 are provided for calibrating the sensor, from which the corresponding calibration solutions can be fed to the sensor 21.
- the sensor 21 is a potentiometric, ion-selective chemosensor.
- the concentration of the sodium hydroxide solution is measured via the membrane potential. After the measurement, the sample solution is fed to the peristaltic pump via the second channel 19b of the above-mentioned collecting pan 28 for the waste solution.
- a standby circulation line which contains a standby vessel 35, is installed in the analysis section of the hydrogen peroxide sensor 17. From this vessel, buffer solution is continuously fed through the hydrogen peroxide sensor 17 and back into the vessel 35 during the standby phase.
- the standby mode of the sodium hydroxide sensor 21 is carried out by continuously supplying saline solution from a storage tank 36 instead of the sample solution.
- the reference system 22 of the sensor 21 must be cleaned at regular intervals.
- distilled water is transported from the storage system 32 through the reference system 22 instead of the potassium chloride solution, the potassium chloride reservoir 23 being short-circuited with the aid of two hose clamp valves 33, 34 in order to accelerate the rinsing process.
- the changes in concentration can be recorded in time using an exponential equation, so that the equilibrium concentration can be calculated. This eliminates the usual "trial and error method".
- the required amount of reinforcing liquor to be added can be determined by calculation within a maximum of a few minutes. For this it is necessary to indicate the quantity of goods per meter (goods throughput in kg / m).
- the fleet (Q2) taken along by the goods from the impregnation compartment is recorded by calculation.
- the amount of water (Q1) brought into the impregnation compartment by the goods is mostly known or can be reliably determined.
- the exchange factor (f) by iteration
- the following formula is used for this:
- Kt Ko - Mc * Kc / (Q 1 * f * M * v + Mc) * exp ⁇ -t * ((Q 1 * f * M * v + Mc) / Mbo) ⁇ + + Mc * Kc / ( Q1 * f * M * v + Mc),
- Kc concentration of total gain (l / l)
- Mc fleet difference per unit of time (l / min)
