Description

  The present invention relates to a rope-like fiber article or a length in a closed container comprising at least two axially adjacent J-boxes for receiving the fiber article during at least part of the processing time. The present invention relates to a method and apparatus for treating fabric. A driving action in the feed direction is transmitted to the textile article by means of a gas flow of the supply medium adapted to act on the rope or a length of fabric via the supply nozzle means.

  An injection processing system operating in accordance with this so-called aerodynamic system, i.e. an injection or nozzle dyeing machine, is used in the industry in the embodiment of the manifold. These are fundamentally different from hydraulic injection processors in that the supply means acting on the supply nozzle is a gas supply means rather than a processing solution. Therefore, the conditions in the hydraulic injection processor cannot be easily adopted in an injection or nozzle processing system that operates on the aerodynamic principle. As examples of the injection processor based on the aerodynamic principle, for example, there are those described in Patent Document 1 and Patent Document 2. As taught in U.S. Pat. No. 6,057,049, this type of processing equipment is known in which at least two J-boxes placed side-by-side in an axial direction are provided in a processing vessel that can be closed. Each J box is set to circulate by a supply nozzle means coupled to the J box and is folded endlessly at the outlet from the supply nozzle means, or in other words when entering the J box, its endless It comes to receive a rope. Side-by-side J-box supply nozzles operating in parallel communicate with the compression side of a common blower that draws a mixture of steam and air from the processing vessel and supplies it as a supply medium Send it into the nozzle. If there are several J-boxes arranged side-by-side in the axial direction, special precautions must be taken in the supply medium dispersion tube to obtain at least a substantially uniform effect by the supply nozzles of the individual J-boxes. .

  In one type, an endless rope comprising a plurality of J-boxes distributed over the entire length of the processing vessel, so that a corresponding number of endless ropes of fibers can be processed at the same time independently of each other In another apparatus known from US Pat. No. 6,057,056 for the hydrous treatment of a fibrous material in the form of The arrangement is such that the nozzle continues, and the rope outlet opens toward the same J box. A guide tube leading to the J box is connected to the outlet side of the supply nozzle and is pivotable about a vertical axis and can perform a traverse to fold the rope flat. Each of the supply nozzles is exposed to a gas supply medium by its radial blower, which is sucked from the inside of the processing vessel through a suction opening at the bottom in the housing of the radial blower Through the air injection opening and into the supply nozzle. Each radial blower is inserted into the upper opening in the jacket of the processing vessel in a vertical axial orientation.

  When this device is used, only one rope can be processed.

European Patent No. 0133897 German Patent Invention No. C219813593 German Patent Invention No. C24119152

  The object of the present invention is to improve the properties of the manifold for the treatment options of the rope-like fiber article according to the aerodynamic principle described above, thereby providing the possibility of a simple structural mounting form, The advantages of the method are achieved.

  To achieve the above object, the method according to the invention has the features of claim 1. The device according to the invention is the subject of claim 6.

  In the novel method, the rope-like fiber article passes through separate supply nozzle means assigned to this J box before entering each J box, and upon exiting from them, the supply nozzle means In the J box respectively coupled to the supply nozzle means or in the J box adjacent to the J box, or if there is at least one J box, away from this J box It is carried along a predetermined path for carrying the textile article. Within each J box, its own endless rope can continue to circulate for at least part of the processing time, or endless ropes from one J box can each be carried into the J box adjacent to it. . And after passing through that J box and optionally at least one further J box, it may return to the first J box. The endless rope is set so as to be circulated by the supply means that is passed through each of the J boxes.

  Thus, in the new equipment, each J box is assigned its own supply nozzle means, and the supply nozzle means have their rope outlets in each associated first J box or in the first J box. In a second J-box adjacent to or from at least one J-box in a device that receives the outgoing rope in an adjustable manner. The supply nozzle means of each J box is preferably assigned its own blower, which is particularly simple when the blower is fitted with a substantially vertical impeller shaft, for all J boxes The blower impeller shafts are located in at least one common, substantially vertical plane. In a preferred embodiment, the supply nozzle means of the individual J-boxes are supported pivotably about rotation axes parallel to each other, and the device is connected to the supply nozzle means of the J-box and pivots the supply nozzle means. A pivoting device is provided for enabling the rolling.

  The equipment is arranged to receive a rope coming out of the rope outlet of the supply nozzle means of at least one J box and thereby realize a rope return path to the J box preceding it in the rope feed direction A return device may be provided.

  Therefore, according to the present invention, the J-boxes (storage units) can be connected in parallel to each other, so that processing of a single rope as in the current normal injection processing machine can be performed. However, the J-boxes may be selectively connected in line with each other, which allows for savings in current, heat and water consumption, and compared to single rope processing. Higher power value.

  Since multiple boxes can be loaded in parallel in a series circuit, and only a few seams joining the individual ropes are required for the entire batch, connecting storage units one after the other during batch preparation And the loading time when loading the fiber article into the processing vessel is saved and shortened. For example, in an instrument with six boxes in the processing vessel, three J boxes connected in line with each other can be loaded in parallel at once. And for the entire batch of these six boxes, only two seams are required in the fiber rope.

  Depending on the size of the processing method and equipment implemented and the number of J-boxes, connecting the J-boxes in line with each other can be a circulation system for circulating ropes or as a continuous system for entering and exiting ropes. Can be used. In this mode of operation of the equipment, not only the textile article is subjected to a dyeing process etc., but also a washing and bleaching process is carried out, and the inner wall of the processing vessel is adjoined in a sealed manner over a part of the circumference. If the processing vessel is subdivided into processing sections by partitioning, and each processing section includes at least one J box, a more differentiated process of this method is performed within and within the processing section. Can be established within. For example, a water wash and wash solution bath based on the backflow principle can reduce the need for water to about 40% of that required for processing a single rope.

  Further features and modifications of the invention are the subject of the dependent claims.

  In the drawings, four exemplary embodiments of the present inventive subject matter are shown as follows.

  1 to 7 according to the invention in the form of a high temperature post-dyeing machine comprising a processing vessel 1 embodied as a cylindrical boiler that is pressure-proofed and closed at both ends by a welded dish-shaped boiler head Shows the equipment. In the exemplary embodiment shown in FIGS. 1 and 2, six J boxes are provided in the processing vessel 1 and are identified by I-VI. For example, as can be seen in FIGS. 1 and 4, each J-box I-VI is defined by two parallel side walls 3 and a bottom wall 4 joined to the side walls 3. The bottom wall 4 is embodied as a sliding bottom in a generally known manner, either by means of parallel PTFE rods or by using PTFE tiles, both types of excess processing solution being treated Underneath the bottom wall 4 in the container 1 can flow into the room marked 5 in FIG. The side walls 3, also called cloth boundary walls, are each embodied inside with a PTFE coating or as a single piece part in a guide profile and, like the bottom wall 4, reduces friction. An arrangement is obtained. The inner cover 6 (FIG. 4) is joined to the side wall 3 and the J box has a substantially U-shaped design with a rope inlet opening 7 and a rope outlet opening 8. The J-boxes I-VI in the illustrated embodiment each have the same axial J-box width, and for a processing vessel, a 2200 mm diameter can typically be 800 mm.

  As can be seen from FIGS. 1 to 3, the side walls 3 of adjacent J boxes I to VI extend obliquely with respect to the longitudinal axis indicated by 9 of the processing vessel. Forming an angle 10 with the longitudinal axis, correspondingly there is a complementary angle 11 to the cross-section indicated by 12, perpendicular to the vessel jacket wall and to the treatment vessel longitudinal axis 9. Extend. In practice, the angle 11 is about 12.5 ° to 15 °, but depending on the dimensions of the processing vessel 1 and the axial J-box width shown by 13 and 13a in FIG. Other angle values are possible. This is described in detail below.

  For each J box I-VI, there is one filling level sensor 14 (FIG. 4) located slightly below the rope exit opening 8 on the rope exit side, which Output a signal to limit.

  In each of the J boxes I to VI, an opening for attachment and detachment that is closed using the detachable pressure-resistant stopper 15 is placed at the level of the substantially horizontal diameter plane 16 of the processing container 1. A solution extraction container 171 is provided on the back surface of the processing container 1, and communicates with the inside of the container so as to extract the processing agent (liquid) when the liquid exits the fiber article. The contents of the solution extraction container 171 can hold the total amount of the solution minus the ratio of the solution confined in the fiber article, and the article moving inside each J box and the surface of the solution outside the article This state without contact makes it possible to add the solution formulation later.

  A cylindrical socket connector 17, welded to the jacket of the processing vessel 1, spaced above the rope outlet opening 8, leads to the inside of the vessel for each J box I-VI, and this stub is , Placed perpendicular to its axis 18 and connected to the center plane of symmetry, shown at 19 in FIG. The socket connector 17 includes an annular flange 20 at an end thereof, and a blower unit 21 is attached to the flange. The blower unit 21 includes a radial blower impeller 24 that circulates about a vertical rotating shaft 18 and is connected to an electric motor 25 mounted on the upper housing portion 22 and includes an upper housing portion 22 including an impeller housing 23. Is provided. The motor 25 is a rotating current motor whose rotational speed can be adjusted for inverter operation and is designed to adjust the required supply flow. The shaft is sealed from the inside of the housing by a shaft seal 26. A spiral guide baffle 27 (FIG. 5) is placed in the blower housing 23 and diverts the gas medium pumped by the blower impeller 24 into an outer flow tube 28 coaxial with the rotary shaft 18, thereby Communication on the compression side with the impeller housing 23 is established.

  A cylindrical inner jacket 29 is inserted in the socket connector 17 that forms the lower housing part of the blower unit 21 with a slight radial interval, is rotatably supported and is coaxial with the rotary shaft 18. Oriented. The inner jacket 29 is sealed at its outer periphery from the annular flange 20 via, for example, a sealing lip embodied as a grooved cuff and suspended on the annular flange via a flat PTFE profile 31. Supported radially and axially. An internal flow tube 33 extends coaxially with the rotational axis 18 of the jacket 29, and is connected to the inlet of the impeller of the blower as a suction tube and at the oppositely symmetrical end thereof. A suction cone is provided that opens into the processing container 1 at the section. An inner flow tube 33 with a jacket 29 defines a cylindrical extension 28 a of the outer flow tube 28. Thus, two centrally located vertical flow tubes 28, 28 a, 33 are embodied in the blower unit 21, and the flow tube 33 acting as a suction tube is designed in a conical shape from the inner jacket 29. Closed at the bottom (FIG. 4).

  The entire blower unit 21 can be removed from the annular flange 22 and replaced with a blower unit having different power or different pumping characteristics as required. Since the socket connector 17 and the annular flange 20 embodied as a welded flange are the same, when replacing the blower unit, the blower impeller 24 and the impeller 23 of different sizes may be replaced.

  A concentric bearing ring 34 is connected to a rotatably supported jacket 29 via a profile 36 (FIG. 6) so as not to rotate relative to it, and is embodied as an annular nozzle. It carries a cylindrical fabric inlet portion 37 of the nozzle 38. The fabric inlet portion 37 is welded with the diffuser 40 in a generally known manner through an annular gap in the nozzle housing 41 that is welded to the inner jacket 29 and communicates with the outer flow tube 28 that is subjected to pressure by the supply medium. Leading to an inlet nozzle portion 39 defining. Adjacent to the nozzle housing 41 is a support housing 42 that is coaxial with the nozzle portion 39 and secured thereto by a suitable stopper for the PTFE supply tube 43 into which the diffuser 40 discharges. The housing 42 forms a rigid support structure fixed against relative rotation for the adjacent supply tube 43, on which a supply part is formed with the supply tube 43 and, for example, an outgoing rope A larger diameter inlet curve 44 is installed that can be introduced into the J box. This is described in detail below. The supply tube 43 rises slightly at an angle of about 10 ° with respect to the horizontal in the exemplary embodiment shown in FIG. The inlet curve 44 exits at a slight distance from the edge of the J-box inlet opening 7.

  The injection nozzle 45 exits into a cylindrical nozzle housing 41 which is distributed annularly about its axis and communicates with the treatment agent supply line 47 via a flexible hose 46 of PTFE and special steel cloth. . The injection nozzle 45 acts as a sprayer nozzle in the direction of the annular gap embodied between the nozzle portion 39 and the diffuser 40, thus achieving a uniform action due to the treatment agent injection flow on the rope passing through the supply nozzle 38. Is done.

  A cantilever arm 48 is fixed to the back surface of the nozzle housing 41 and extends, for example, as shown in FIG. It is articulated to the passing thrust rod 49. The thrust rod 49 communicates with a pneumatic push-up cylinder 51 that can be replaced by a threaded spindle or some other actuating drive. Accordingly, the operation of the push-up cylinder 51 causes the supply nozzle 38 and the supply portion 43/44 to pivot about the vertical rotation shaft 18 of the blower unit. For example, as shown in FIGS. 1 and 2, since the thrust rod 49 is connected to the cantilever arms 48 of all the blower units 21, when the push-up cylinder 51 is operated, the supply nozzles and the supply parts for all the J boxes are , Are simultaneously pivoted at the same angle about each vertical pivot 18 and are therefore firmly connected to each other. Also for the supply nozzle 38 and the supply part 43/44 of the further blower unit 21, which is identified in FIG. 1 and FIG. 2 by 0 and is defined in one side by the pan-type boiler head 2. It is the same. This will also be described below.

  Below the cloth inlet portion 37 of each supply nozzle 38 in the processing vessel 1 is a deflection roller 52 supported in a freely rotating manner around a horizontal axis, which deflection roller 52 is connected to all the J in the processing vessel. It may selectively extend continuously along the box, or it may have its own deflection roller 52 in each J box or group of J boxes. As shown in FIG. 7, each deflection roller 52 is connected to a toothed belt drive 54, which is in the processing container 1 and embodied as an electromagnetic coupling, for example. It is fixed by a guard baffle, extends out of the processing vessel 1 and is driven by a geared motor 56. Generally, the deflection roller 52 has a smooth surface. A rotation speed monitoring device is assigned to the deflection roller 52, whereby the rope running can be monitored. As shown in FIG. 4, the deflection roller 52 allows the cloth to travel reliably without being reinforced by the driven skein winder. As a result, the cloth enters the supply nozzle 38 vertically, and the suction flow acting in the same direction as the blower unit 21 reinforces the cloth entering. Usually, the deflection roller 52 is free to rotate. The temporary drive of the deflection roller for when the fabric stops has the task of pulling the rope freely. This is accomplished by connecting the free rotation deflection roller 52 to a drive motor 56 with a joint 53.

  In FIG. 6, a slightly modified embodiment is shown in which a rope enters the supply nozzle 38. Between the free rotation deflection roller 52 and the cloth entrance path 37, a further free rotation guide roller 57 accommodated so as to be pivotable is provided. In the position pivoted upward, indicated by the solid line in FIG. 6, the guide roller 57 does not intervene in the rope travel. When pivoted down to the position indicated by the dotted line, the wrap angle of the deflecting roller 52 is increased, thus improving the removal of the solution still remaining in the rope network and therefore with the rope the supply nozzle 38. The amount of solution introduced into it is reduced. If it is not necessary to reach the rated speed, the power source of the drive device for the free rotation deflection roller 52 can be optionally turned on. Adjustment of the guide roller 57 is effected by a pneumatic push-up cylinder indicated at 58.

  1 and 2, for example, the blower unit 21 with the combined supply nozzle 38 and the supply part 43/44 of all boxes I to VI and the intermediate box 0 is parallel to the longitudinal axis 9 of the container. It is shown that it is placed on a common vertical surface 59 with a vertical pivot (18). Thus, the spacing 60 (FIG. 3) of all pivots 18 from the longitudinal axis 9 of the container is equal. Moreover, as already mentioned above, the pivot 18 of each supply nozzle 38 extends to the vertical central plane 19 of the combined box. The spacing 61 between adjacent pivots 18 is also equal. The pivot range indicated by 62 for each supply nozzle 38 is that in a first position, the supply nozzle 38 with adjacent supply portions 43/44 is connected to the central plane 19 of each J-box I-VI. And in the middle box 0 of the plane 19a parallel to it, it is chosen to be placed with its longitudinal central axis intersecting the pivot axis 18, which is in a symmetrical position opposite the side wall 3 On the other side, as well as the longitudinal center plane 19 of the joined J-boxes, extend from the sidewalls of adjacent J-boxes with the same axial spacing. This setting is illustrated in FIG.

  All supply nozzles with a combined supply part 43/44 at the second position of the supply nozzle 38, which can be set by suitable actuation of the push-up cylinder 51 and at the other end of the pivoting range 62 1 is pivoted to the left in FIG. 1, in particular until the inlet curve 44 of each supply nozzle 38 in the first J-box exits in the middle in the adjacent second J-box. That is, the rope exit opening of the entrance curve 44 is at the center point of the center plane 19 in the longitudinal direction of the second J box. Thus, a rope is sent from the first J box to each adjacent second J box.

  The feed nozzle 38 and feed portion 43/44 of the J-box VI on the left of FIGS. 2 and 3 adjacent to the pan boiler head 2 are in this pivoted position, together with an inlet curve 44, a cylindrical chute ( scray) 620 (FIG. 4), which is in the chamber between the dish-shaped boiler head 2 and the side wall 3 adjacent to that of the J-box, whose orifice enters this chamber Align with the orifice of the incoming inlet curve 44. The return chute 620 extends along the process vessel 1 and exits the rope return tube 63 which is outside the process vessel and exits from the bottom in the middle J-box 0 via the funnel portion 631. This position of the supply nozzle 38 and the combined supply part 43/44 is shown in FIGS.

  As can be seen from FIG. 3, the pivot range 63 is embodied symmetrically with each cross-section 12 extending through the corresponding pivot 18. Thus, along the diagonal position of the side wall 3 of the J box, the inlet curve 44 of each supply nozzle 38 always exits from the center in each J box, both in the setting of FIG. 1 and in the setting of FIG. Achieved. The center point of the rope exit opening of the inlet curve 44 is always in a common vertical plane 630 that extends parallel to the longitudinal axis 9 of the processing vessel. Thus, for both the setup of FIG. 1 and FIG. 2, the same situation is obtained that folds flat in the J box, which is very important for proper fabric travel.

  The pivot range 62 is adapted to the oblique position of the side wall 3 of the J box. This is twice as large as the angle 11 shown in FIG.

  FIG. 3 shows the effect of pivot angle 62 on J box width 13 or 13a for the same process vessel diameter 64 and the same axial blower spacing 60. FIG. The pivot angle range 62 on the left side of the drawing is 25 °, and the pivot range 62a on the right side of the drawing is 30 °. The result is, for example, a rated box width 13 of 700 mm at 25 ° and a rated box width 13a of 800 mm at 30 °. Therefore, the interval 61 of the blower unit 21 or in other words, the pivot 18 parallel to the longitudinal axis of the processing container 1 also increases, for example, from 740 mm of the interval 61 to 840 mm of the interval 61a. Over the entire length of the processing vessel 1, the blower units 21 form a row in which the respective blower units are placed vertically. Since the cloth entry path is on the back surface of the cloth inlet portion 37 (FIG. 4) in the region of the impeller shaft 18, excellent running characteristics of the cloth occur.

  The inside of the fabric inlet portion 37 that includes the nozzle portion 39 relative to the nozzle portion 39 is coated with PTFE or designed using PTFE.

  In the operation mode of FIG. 1, the individual J boxes I to VI are connected in parallel to each other. Within each J box, an endless rope is circulated by a combined supply nozzle 38. Thus, the processing of one rope can be performed in each one of the J boxes.

  In the setting of FIG. 2, J-boxes I-VI are connected in series with each other during operation, resulting in a circulation system for circulating endless ropes, which endless ropes are each adjacent from one J-box. After moving to the J box and returning to the last J box 6 in the row, it passes through the rope return tube 63 to the middle box 0 and from there to the first J box I by means of a combined supply nozzle. Will be introduced again. In this setup, as an alternative, the instrument can be used as a continuous system where the rope enters the processing vessel 1 or intermediate box 0 and exits from the last J box VI.

  In this regard, in the exemplary embodiments of the various processing methods, see also FIG. 8, FIG. 9, which also briefly shows the additional equipment required for the processing method for adding processing agents, etc., in an integral part. However, a brief description will be given below.

  FIGS. 8 and 9 very schematically show a hot post-dyeing machine with nine J-boxes I to IX and ten blower units 21, each with a combined supply nozzle 38 and adjacent to it. The supply parts 43 and 44 are provided, and only the supply nozzle 38 is represented by a circle. One such unit is assigned to each of the J boxes I to IX and the intermediate box 0. The supply parts 43, 44 are in the position of FIG. That is, the machine is set for continuous circulation operation. The rope return line 63 is indicated by a dotted line. The pneumatic cylinder 51 is in the position of FIG. The interior of the processing container 1 is subdivided into three processing sections X, Y, and Z, each of which includes three J boxes I to III, IV to VI, and VII to IX, respectively. The partitions separating the three processing sections from each other are two J-boxes embodied as box partitions extending from the lower part to the jacket of the processing vessel and connected to the inside via sealing lips This is provided by the side wall 300. Box divider 300 extends upward beyond the maximum solution level. These are between J box, III and IV and VI and VII.

  The solution withdrawal container 171 is also subdivided into three partial containers by a corresponding partition 170, each connected to one of the processing sections X, Y, Z. Corresponding to the three processing sections X, Y, Z, three processing agent injection systems are provided, each for heating and cooling one solution filter 70, one injection pump 71, and the processing solution. 1 heat exchanger 72. 73 shows a shut-off valve starting from the compression side of the injection pump 71 downstream of the heat exchanger 72. The shut-off valve is configured to remove a processing solution from a solution extraction container 171 coupled to each processing section X, Y, Z. It is for returning to a part of. The circulating processing solution is pumped by the combined jet pump 71 into each solution supply line 47 (FIGS. 4 and 7) of the supply nozzle 38 in the adaptable group J-box and in the combined line. Has a shut-off valve 74 for running the treatment solution forward. The outflow fixture for each of the processing sections X, Y, Z is indicated at 75. A supply container 77 for treated water, untreated water, soft water, and warm water (about 60 ° C.), or an initial solution container for a treatment bath communicates with the suction side of the injection pump 71 via the respective cutoff fixtures 74. . Two initial solution and replenishment solution containers 78 for the treatment solution are also provided, each of which can be communicated to the suction side of the injection pump 71 via a shut-off valve 79. The shut-off valve 79 and the combined line connection are shown for only one of the initial and replenishment solution containers. A steam source is indicated by 80, and a condensate diverter 81, a pressure reducing valve 82, and a regulating valve 83 are provided downstream of the steam source. By this source, the inside of the processing vessel 1 can be directly exposed to steam. Finally, a switching / deadline armature is also shown at 84 on the suction side of the injection pump 71.

[Example 1]
In a high temperature post-dyeing machine with nine J-boxes I-IX, alkaline hydrogen peroxide bleaching is performed on knitted cotton products with lattice bonds as pre-bleaching for subsequent reactive dyeing operations. The lattice product has an 80 cm cylindrical width that is not incised. The weight per unit of surface area is 190 g / m ² , which corresponds to an extended metric weight of 300 g / m, and for a batch weight of 9 times 150 kg per box, this is a total batch of 1350 kg for a 4500 m fabric length. Equivalent to.

The thickness of 0.8mm of the fabric, the batch corresponds to the substrate deposition VS volume Vtex and 6.0 m ³ of 5.76M ^3, which corresponds to the intermediate chamber volume VZ of 4.86M ³ . For an average solution loading of 80%, this volume is 3.89 m ³ .

  The entire batch, in preparation for loading into the machine, is three connected pieces, each 1500 m.

  In the initial solution container 77, a pre-bleaching treatment bath is set at 2500 ° C. at 50 ° C.

  The bath contains a wetting agent, 32.5% caustic soda, 35% hydrogen peroxide, and a bleach stabilizer additive.

Loading the entire batch into the machine Pneumatic cylinder 51 (FIG. 2) is placed in the position of the circulation system of FIG. This is also activated by a control unit 85 that transmits the reciprocating traverse to the inlet curve 44 along the thrust rod 49 across the J box width, so that the feed portion 43 together with the inlet curve 44 is for each J box. Functions as a rope piler. In order to monitor the loading operation, all the stoppers 15 in the area of the blower unit 21 are opened.

  The blower unit 21 is designed with a cloth inlet 37 and a nozzle portion 39 for self-suction of the rope, so that a forward feed piece or belt is not required for the loading operation.

  For loading into the processing vessel 1, the tip of the rope loading from the 3 pile cloth is introduced by the stopper 15 of the blower unit 21 of the box 0 intermediate between the J box III and the J box VI, and the 3 pile cloth Since the end of the rope is fixed to the same stopper, the end of the rope is fixed after entering. After the blower unit 21 of J box 0 is powered on, the blower unit pulls the first rope in. The J box III and VI blower units are then powered on with a delay of approximately 5 seconds, so that the three ropes enter J boxes I, IV, and VII in parallel with each other. In order to reinforce the running of the cloth in the box, the blower on the exit side of the incoming J box is also turned on. The next J box blower unit 21 is turned on with a delay corresponding to this time.

  The injection nozzle 45 (FIG. 4) is exposed to the processing solution via an injection pump 71 connected to an adaptable group of J-boxes in open communication with the initial solution container 77.

  After the rope-shaped cylindrical cloth enters, the various blower units 21 concerned and the shut-off valve 74 connected to them are turned off. The end of the incoming rope that reaches the stopper 15 of J box III, VI or intermediate box 0 is bound with the end of each adjacent rope to create an endless rope with three seams. From each of the stoppers, it is monitored that the fiber article enters the blower unit 21 corresponding thereto, but this stopper 15 is closed.

  When the blower unit 21 and the supply part 43/44 are set for circulation system operation, the traverse power supply of the inlet curve 44 is turned on, and the blower unit 21 and the injection pump 72 are turned on, the opened initial solution container 77 The reached initial solution bath is evenly distributed throughout the article. The blower unit 21 is adjusted to a cloth circulation speed of 400 m / min.

  By monitoring the level in the solution withdrawal container 17, the level in the processing container 1 is corrected after the initial solution bath is introduced from the initial solution container 77 through the valves 73 and 74. The treatment solution is kept constant at 60 ° C. for 10 minutes and then heated to a treatment temperature of 90 ° C. with a ramp of 6 ° C./min and maintained for 20 minutes upon direct steam power from the vapor source 80. The

  During this time, in the initial solution container 77, a first water wash bath is prepared with a bath volume of 2500 l at 80 ° C.

  The treatment bath (bleaching bath) in the treatment vessel 1 is drained after 20 minutes by opening the ventilation valve 90 and the drain valve 75, and the first washing bath is fed to the treatment section X via the injection pump 71. , Y, Z are distributed over the ropes of three groups of J boxes.

  The washing water dripping in the J box enters the solution extraction container 17 and is again sucked by the injection pump 71 via the switching fixture 84.

  Circulating water wash is maintained for 5 minutes.

  Within this time, the second rinsing bath added acetic acid into the initial solution vessel 77 using 2500 liters of rinsing water at 60 ° C. to neutralize the product against the residual concentration of hydrogen peroxide. Be prepared. After the first rinsing bath is drained, based on the backflow principle, the second rinsing bath is carried through the three groups of J boxes, and the first group of boxes containing J boxes VII, VIII, and IX. From the second group of J-boxes IV, V, VI through the switching fixture 84 and the injection pump 71 respectively coupled thereto, and after passing through them, the third group of J-boxes I, II. , III, then pumped to drain. In this reverse flow process, the subsequent reactive dyeing is performed at a constant temperature of 60 ° C., so that the temperature of the washing water is kept constant at 60 ° C.

  For the 3.5% reactive dyeing planned after the alkaline hydrogen peroxide bleaching is performed, after the constant temperature dyeing at 60 ° C., the non-fixed reactive dyes are washed away and the residual chemicals from the dye bath are removed. Neutralized at the same time.

  The water wash cycle is more comprehensive than the peroxide bleach cycle described above and is therefore more time consuming.

  In order to reduce the total processing time, the boxes can be divided into groups of different numbers of boxes (eg 1-4 boxes). And since time can be shifted by the water-washing part, based on the order of the water-washing part, an effect | action can be exerted simultaneously with respect to textile goods by the water-washing bath which has a different water-washing temperature and a different residual density | concentration.

  Regarding the breakdown of the washing cycle in the reactive dyeing described as an example in the present specification, concentration uniformity is achieved in the first washing bath and bath circulation at 50 ° C., and the reverse flow principle is used for neutralization. A second bath at 50 ° C. is then provided, and then by using a staggered water wash temperature of 85 ° C. to perform warm water wash to neutralize residual alkali and direct steam from the steam source 80. Can also be turned on. In order to accelerate the wash-off process, a further spray nozzle (not shown) is switched on, facing the surface of the incoming welding rope in the box part.

  After the same working process after warm water washing, based on the backflow principle, two initial water bath solutions at 50 ° C. and one initial water bath solution at 30 ° C. are carried out in an offset connection. That is, after passing through the first group of boxes and being switched to the second group of boxes, the next subsequent flush bath may already be switched to the first group of boxes.

  When the rinsing solution is drained from the last rinsing bath, the rope stops at box IX after seam sensor 87 (FIG. 4) reports the seam. The rope is cut off, and the piece opposite to the cloth traveling direction is conveyed from the J box IX through the stopper 15 and welded through the discharge stake winder in the rotary carriage. The power of the blower unit 21 of the J box that is emptied at the time of discharge is automatically turned off.
