Definitions

  • the textile goods are to be in circulation in the form of an endless fabric rope in a closed vessel by means of a transport (or conveyance) JET-System in the form of a JET-Nozzle, which is impinged to a conveyance current, which provides to the fabric rope its feed movement in the prescribed rotation context.
  • the transport medium in this context, in most machines, is a processing bath or liquor to which additives can be mixed depending upon the process-specific parameters and which can be brought to different temperatures during the course of the process.
  • flushing operations are necessary, in which substances, which have an affinity to the textile goods or get attached to their surfaces are found, and must be flushed out, after they have been subjected to preparatory processes such as desizing or scouring, bleaching, washing, saponification etc., and are brought, to start with or simultaneously to the flushing operations in solution, emulsion or dispersion.
  • preparatory processes such as desizing or scouring, bleaching, washing, saponification etc.
  • the flushing takes place between two different levels of the scouring liquor in the vessel.
  • the circulation movement of the fabric rope during the flushing operation is not interrupted through a filling and discharging operation of the finishing/processing liquor.
  • the rinsing/flushing liquid is circulated through a circulation pump, generally the floatation pump, during the processing period, whereby, using corresponding control of the flushing liquid inflow in the vessel and of the flushing liquids discharge from the vessel, a flushing liquid level is maintained in the vessel, which oscillates or fluctuates between an upper and a lower level (the minimum level for a perfect operation of the circulation pump).
  • the success of the flushing can be determined similar to the case of batch flushing, through ascertaining the dirt content of the discharged flushing liquid.
  • a third process is finally the flushing or rinsing with overflow.
  • the dirt-loaded processing liquor contained in the vessel is continuously added with scouring liquid, general water, while the excess processing bath, made thinner by the scouring liquid, is discharged continuously up to a certain level, which level is determined by means of an overflow tube.
  • the success of the flushing is obtained in this case through a continuous thinning of the process bath; it can be ascertained through corresponding monitoring of the processing bath, made increasingly thinner, that gushes out through the overflow pipe.
  • the batch flushing and the flushing between two different levels are the most efficient in the context of the scouring liquid consumption; that means generally water consumption.
  • the flushing liquid consumption under the overflow rinsing process is the maximum, with the result that this flushing or rinsing process is inefficient, in the context of flushing/scouring liquid consumption.
  • the task of the invention is therefore to design a flushing or rinsing process for hank formed textile products on JET-Processing machines, which allows to keep the minimum the flushing liquid consumption to the minimum, that means generally the rinsing water consumption, and the time required for carrying out the flushing operation, and to dovetail or match them corresponding to the respectively applicable conditions and peculiarities in such a manner that the production cost for the entire wet finishing process requiring a flushing operation is minimized.
  • the invention proceeds from the knowledge that in jet processing machines based on aerodynamic principle the transport of the endless product flow is independent of the processing liquor, because the fabric flow takes place through the impingement of the Venturi-Nozzle with a gaseous transport medium, where applicable, supported by an externally driven roller, and therefore offer new possibilities for the flushing operation.
  • the procedure adopted, in accordance with the invention is therefore the following: the textile product in the form of an endless fabric rope is set in motion by means of a Venturi-Nozzle in a closed vessel through a gaseous transport medium.
  • the textile product is subjected to the effect of a flushing or scouring liquor/liquid in such a manner that the rinsing/flushing is undertaken with continuously flowing scouring liquor.
  • the rinsing liquid application per time-unit is controlled optimally through and/or the speed of fabric rope movement, which depends on products-specific-data of the textile article, the machine-specific-data and the process-specific-data.
  • the dirty rinsing liquid exiting from the nozzle is discharged from the vessel.
  • this objective can be achieved in the following fashion: From product-specific data of the textile article, for example, weight, substrate and the making-up of the fabric rope, from design-dependent data of the nozzle such as jet diameter, jet length etc. and from specific data relating to the processing such as circulation speed of the fabric rope and such other factors, a computer model is evolved which images or simulates flushing or rinsing process and its success. The control of the throughput of the flushing liquid per unit through nozzle and the rope circulation speed is effected through a computer based on the prescribed computer model.
  • the computer model can be analyzed through the data obtained during the flushing operation. Apart from this, the computer model can be compared and calibrated through simple tests with data obtained in actual rinsing exercise.
  • the invention-related process under which a direct rinsing or flushing of the product with scouring liquor takes place can now be so designed that the success of the rinsing operation can be continuously monitored online or in prescribed time intervals.
  • the data so obtained for the respective success of the flushing can flow into the control and particularly in the computer model in order to modify the flushing operation automatically or to specify the end of the rinsing operation.
  • the modification of the rinsing operation for instance, can be done in such a manner that the application of the rinsing liquid on the rope is different, particularly higher at the beginning of the flushing operation, that means during the first rotation or circulation of the rope, than towards the end of the rinsing operation.
  • the dirt-load of the dirty rinsing liquid represents a measure or a yardstick of the rinsing effect achieved.
  • the measurement of the dirt extent can be done in the rinsing water exiting from the vessel and/or directly on the fabric rope.
  • the following criteria measured through among corresponding sensors and/or calculated through the computer, can be used.
  • the invention based process enables, with the knowledge of the data required for the flushing process, to optimize the flushing process.
  • the control of the water consumption and/or the required production time itself can be calculated, depending upon the production conditions, such as price of water, magnitude of production and such similar parameters respectively applicable.
  • the control system needs from the operator or the programmer of the wet processing/finishing machine only information whether the flushing process should be optimized in the context of the water consumption or with reference to the production time.
  • FIG. 1 A jet-processing machine in accordance with aerodynamic principle, installed for carrying out the flushing process in accordance with the invention, in schematic illustration and in cross section.
  • FIG. 2 A diagram for clarification of the concentration decrease of the dirt load in the dirt containing rinsing water in the execution of the flushing process as per the invention, as a factor of the number of the fabric rope circulations, under demonstration of the matching or dovetailing between the measured and computed concentration values.
  • FIGS. 3 & 4 Two diagrams for clarifying the flushing time and the water consumption, depending on the rinsing water quantity injected in the nozzle and the rotation speed of the fabric rope, under utilization of the invention-based process, and
  • FIG. 5 A diagram for illustrating the counter running course of the flushing time and the water consumption in the execution of the flushing process as per the invention.
  • the high temperature (HT) piece dyeing machine schematically illustrated in FIG. 1 has a pressure-resistant cylindrical vessel 1 , in which there is an opening 3 for operation purposes, which opening can be closed by means of a lid 2 , through which a fabric rope 4 can be brought it.
  • the fabric rope 4 is guided through an externally driven roller 5 in a Venturi-nozzle 6 , to which a plaiter 7 is attached.
  • the plaiter 7 places the fabric rope 4 exiting from the nozzle 6 in storage 8 after duly plating it, from which the endless fabric rope is again pulled out through the roller 5 .
  • the roller 5 and nozzle 6 are accommodated in the housing parts 9 , which are connected to the vessel 1 in a leak-proof manner.
  • the fabric rope 4 is tied after placing it through the opening for operation 3 at its ends to form an endless fabric rope.
  • the nozzle 6 is impinged to a gaseous transport medium current, which puts the fabric rope 4 in circulation, in the rotation context illustrated through arrow 10 .
  • the transport medium in the above case is air or steam-air compound, which is sucked through a blower 11 and a suction pipe 12 from the vessel 1 and is conveyed through a compression pipe 13 in the nozzle 6 .
  • a focus pipe 14 is arranged which includes a liquor filter 15 and is connected with a suction pipe 16 of a liquor circulation pump 17 , the compressed pipe 18 of which has a heat exchanger 19 and converges through a regulating valve 20 in the nozzle 6 .
  • the liquor circulation pump 17 enables to have the liquor sucked from the vessel 1 circulated through the nozzle 6 and the vessel 1 .
  • Parallel to the heat exchanger 19 and the liquor circulation pump a bye pass pipe 22 is provided, which includes a shut-off valve 23 and connects the focus pipe 14 with the compressed pipe 21 .
  • dosing tank 24 which contains in watery solution, emulsions or dispersions a chemical additive material, which can be supplied through a dosing pump 25 and a jointing pipe 26 in the suction pipe 16 of the liquor circulation pump 17 .
  • a dosing pump 25 and a jointing pipe 26 in the suction pipe 16 of the liquor circulation pump 17 .
  • the piece dyeing machine described hitherto, working in accordance with aerodynamic principle is perse known. If in the course of a processing operation it is necessary to rinse or flush the fabric rope 4 , the process adopted is as follows:
  • a discharge valve 17 of the focus pipe 14 and an inlet valve 28 in the suction pipe 16 of the liquor circulation pump 17 are opened.
  • the inlet valve 28 rinsing water gushes into the suction pipe 16 , as denoted through an arrow 29 .
  • the incoming rinsing water can be added from the dosing tank 24 , where applicable, with the additive, which simplifies or supports the flushing operation, and is brought to the heat exchanger 19 at a purpose specific rinsing temperature, before it enters the nozzle 6 .
  • the blower 11 is switched on and conveys the transport/conveying air stream circulating through the pipe 12 , 13 , the nozzle 6 and the vessel 1 , which drives the fabric rope 4 in the direction of the rotation.
  • the rinsing water entering the nozzle 6 is brought to the product, which builds the fabric rope, in the nozzle 6 .
  • the fabric rope 4 pulled out by the roller 5 from the storage 8 is drenched at the entry in the nozzle 6 with the dirt particle-loaded liquor, which is brought to the nozzle 6 through the fabric rope.
  • In the nozzle 6 there takes place a mixing of the dirt-loaded liquor, which lands into the nozzle through the fabric rope and the rinsing water quantity added through the injection using the compressed pipe 21 .
  • the dirty rinsing water exiting from the nozzle 6 is captured in the vessel 1 , and is let out through the focus pipe 14 and the outlet valve 27 , as denoted through the arrow 30 .
  • the suction pipe 15 is shut-off through a shut-off valve 31 against the suctions side of the liquor circulation pump 17 .
  • the dirty liquor contained in the fabric rope is diluted in an increasing measure through the rinsing water injected through the nozzle 6 , till finally the respectively endeavoured flushing success is reached.
  • the entry of this flushing success can be determined through sensor device 31 online, through which the dirty rinsing water gushing from the vessel 1 flows.
  • the sensor device 32 monitored for instance the pH value, the electrical conductivity and the turbidity of the outgoing rinsing water and transmits electrical signals, which characterize and corresponds to these parameters, as data to a computer 33 of the control system.
  • the addition is again stopped and the piece dyeing machine is made ready for the next following wet finishing/processing step.
  • the fabric rope is driven through the air stream conveyed by the blower 11 independent of the rinsing water quantity injected.
  • the rotation speed of the fabric rope 4 can be continuously altered, while the control valve 20 allows modifying the rinsing water quantity injected per time unit, with controls from a computer 33 .
  • the rotation speed of the fabric rope 4 can be altered also thereby that the computer 33 controls a butterfly valve 34 in the compressed pipe 13 in the downstream of the blower 11 .
  • the injected rinsing water quantity can also be modified through a control intervention on the circulation pump 17 , as is denoted in FIG. 1 .
  • the quantity of the dirt particle-loaded liquor brought into the nozzle 6 with the fabric rope 4 depends primarily on factors such as weight, substrate and the making up of the fabric rope 4 . From this a calculation is made how many litres of liquid can be absorbed by the fabric rope. The quantity of the actually consumed liquid, in relation to the weight of the fabric rope, results in the so-called “pick-up A”. Moreover it is dependent on the speed of the fabric rope 4 , the dirt particles contained liquor quantity brought in the nozzle 6 with the fabric rope depends therefore directly on the rotation speed of the fabric rope. Building from this knowledge, it is possible to generate a computer model, which simulates the success of the flushing. This computer model can be compared and calibrated through tests with the practical conditions. FIG. 2 illustrates the result of such comparative tests between the theoretical computation and the actual measured values.
  • the dirt concentration is recorded in gram per litre in the dirt particles loaded rinsing water exiting from the focus pipe 14 , depending upon the number of the circulation of the fabric rope 4 . Both the curves show that the concentration during the first rotation of the fabric rope steeply falls down and, with increasing number of the rotation of the fabric rope approximates asymptotically a minimal residual value. There is a good agreement between calculation and actual measurement.
  • the design example which forms the basis for FIGS. 3 to 5 is applicable for a cotton textile product with an average square meter weight of 250/m and with following parameters: pick-up percentage 330 Storage Load KG 200 Starting Dirty Intensity (gram/ltr.) 35 Residual Dirt Load at the end of 3 The Flushing time (gram/ltr.)
  • Tables 1 and 2 show that through variation of the rinsing water quantity per time unit (injection quantity) and the speed of rotation of a product, as illustrated through the dark shaded fields of the table, for instance, a time saving by 75% can be achieved, while simultaneously the required rinsing water quantity increases only by 38%.
  • the illustrated design example shows that under lower rinsing water costs, at the cost of an enhanced flushing/rinsing water consumption, the product quantity produced and thereby the income can be significantly enhanced, because the rinsing time is shortened, while under high flushing water costs by extension of the flushing time and, necessitated by it, through application of additional machine capacity the expenditure could be significantly reduced.
  • the rinsing liquid is ejected in nozzle 6 ( FIG. 1 ) and thus brought on to the fabric rope 4 .
  • the new rinsing/flushing process can be carried out also in such a manner that the rinsing liquid is brought on the path of the fabric rope and/or after the nozzle 6 on the fabric rope 4 .
  • FIG. 1 schematically, as an example.
  • a rinsing liquid pipe 24 emerging from the compressed pipe 21 converges.
  • a control valve 35 which can be controlled by computer 33 . What is achieved there with is that the product stream entering in the nozzle 6 is already loaded with rinsing liquid.
  • the pipe 34 need not necessarily converge in the area above the roller 5 . Depending upon the respective peculiarities convergence of pipe 34 can happen somewhere between the roller and the annular gap of the Venturi-Nozzle 6 . Besides this, even design forms can be thought of in which the convergence of the pipe 34 lies in the movement path of the fabric rope 4 (vertical), located between the storage 8 and roller 5 , and the rinsing liquid is brought on the fabric rope 4 already before it reaches the roller 5 .
  • this variant is denoted with a “dot-and-line”, which reproduces a compressed pipe 34 a provided with a regulation valve 35 a , which similarly can be controlled by computer 33 .
  • the dirt particles containing flushing liquid emerging from the fabric rope 4 is captured in the vessel 1 and is discharged through the sump and the outlet valve 27 .
  • the following method can also be adopted.
  • dirt particles containing rinsing liquid are discharged from the vessel branch-wise, that means the rinsing liquid is captured in the vessel in order to be added later for a reuse.
  • the sensor device 32 for determining the achievement of the flushing success need not necessarily be located at the rear of the outlet valve 27 , in order to monitor the exiting rinsing liquid mixed with dirt.
  • the measurement or determination of the data characterizing the extent of dirt can also take place directly on the fabric rope.
