Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sliver dye fixing device for fixing the dye on fibers of a sliver to which dye has been applied by a method such as decontamination.

[Conventional technology]

Printed products are usually obtained by applying dyes to textile products such as woven fabrics and slivers by printing a dye-containing printing paste into a predetermined pattern. At this stage, the printing paste is simply attached to the surface or between the fibers of the processed textile product. Therefore, after applying the dye, a step of fixing the dye to the fiber is necessary in order to chemically bond the dye in the printing paste to the fiber of the printed product.

Dye fixation on such printed materials has traditionally been done using a batch method, in which the printed material is placed in a steamer called a kya, the vacuum is evacuated, steam is blown in to deaerate the printed material, and the dye is fixed using steam heat. However, in recent years, J.
- A method of continuously fixing dyes using a box-type steamer or the like is being praised for its superior production efficiency.

[Problem that the invention seeks to solve]

However, when using the continuous dye fixing method described above, it is easy to degas the air and raise the temperature inside the fiber sufficiently when the fabric is thin and has a low air content. Although it can be carried out efficiently, it has the disadvantage that it cannot be carried out efficiently when the target is a sliver or the like with a large air content. That is, for slivers, it takes time to degas the air and raise the temperature inside the fibers sufficiently, and it takes a long time to fix the dye to the fibers, resulting in extremely poor production efficiency.

This invention was made in view of the above circumstances, and it is possible to easily deaerate the air from slivers with a high air content and sufficiently raise the temperature inside the fibers, thereby fixing the dye in a short time. The purpose of the present invention is to provide a sliver dye fixing device with high production efficiency.

[Means for solving problems]

In order to achieve the above object, the dye fixing device for sliver of the present invention is a dye fixing device for fixing the dye of the dye-applied sliver to the fiber, and the dye fixing device is a dye fixing device for fixing the dye on the fibers of the sliver to which the dye has been applied. a far-infrared heater; a first steam discharge device located below the far-infrared heater and discharging steam in the direction of the far-infrared heater; and a sliver inlet and outlet, the far-infrared heater and the first steam A first casing that accommodates a discharge device, a deaeration port provided on the upper side of the first casing, a second steam discharge device that discharges steam upward, and a sliver inlet and source. a second casing provided with the second steam discharge device on the bottom; a deaeration port provided in the second casing;
and a sliver transport means for transporting the sliver so that the sliver passes through the casing in this order.

In the present invention, the term "sliver" is used to include not only slivers in a narrow sense, but also all fiber products having width and thickness, such as wider webs.

That is, unlike conventional sliver dye fixing devices that simply utilize steam heating, this invention improves internal permeability to objects, ease of absorption,
Using a far-infrared cotton heater that has excellent direct heating properties using radiation, preheating is performed by combining heating with this heater and steam, and by performing this preheating prior to full-scale steam heating, the air content can be reduced. Even for slivers with a large amount of water, the air is degassed and the temperature inside the fibers is rapidly raised to a sufficient extent, thereby significantly shortening the fixing time of the dye.

Next, the present invention will be explained in detail based on examples.

〔Example〕

FIG. 1 shows an embodiment of the invention. This sliver dye fixing device 1 includes a first casing 2 that preliminarily heats a sliver 5 that has been subjected to Vigoro printing, etc. and at the same time deaerates the air held inside the sliver 5.
and a second casing 3 for fixing the dye of the sliver 5 after the preliminary heating and degassing.

The first casing 2 has a box shape and has a deaeration port 4 in the ceiling, an inlet 6 for the sliver 5 in the lower part of one side, and an inlet 6 for the sliver 5 in the upper part of the other side opposite to the one side. It has a sliver 5 discharge lower. Inside the first casing 2, a net conveyor 8 is disposed on an upward slope as shown in the figure for taking in the sliver 5 through the inlet 6 and conveying it to the discharge lower.
Slivers 5 are placed on both sides of the net conveyor 8.
A plurality of far-infrared heaters 9 are installed while maintaining a gap through which
A heater block consisting of - On the other hand, a plurality of steam discharge ports 1 are provided at the bottom of the first casing 2.
0 is provided, and the steam for steaming the sliver 5 is discharged in the direction of the far-infrared heater 9. A part of the discharged steam is replaced with the air inside the sliver 5, and the remaining steam and the air expelled by the steam from the inside of the sliver 5 are discharged to the outside of the casing 2 from the degassing port 4. . In this case, the net conveyor 8 that conveys the sliver 5 has an upward slope and has a structure that follows the rise of steam (due to thermal convection), so the air in the sliver 5 and the steam from the steam discharge port 10 It becomes easier to replace. Note that 31 is a guide plate that drives and folds the sliver 5 falling from the discharge lower (left and right), and is driven by a motor (not shown).

The second casing 3 installed alongside the first casing 2 is provided downstream of the first casing 2 with respect to the flow of the sliver 5, and is a cylindrical body having a 3-shaped appearance. It is. One end opening on the upstream side of this casing 3 serves as an inlet 1) for the sliver 5, and the other end opening on the downstream side serves as an outlet 12 for the sliver 5.

On the outside of the discharge port 12, there is a means for extracting the sliver 5 from the casing 3 by pulling it.
(not shown) is provided. By adjusting the speed at which the sliver 5 is taken out by the taking-out means and the conveyance speed of the net conveyor 8, the time during which the sliver 5 passes through the casings 2 and 3 can be adjusted. Further, a plurality of steam discharge ports 13 are provided at the bottom of the second casing 3 for discharging steam so that the steam moves from the bottom to the top in the casing 3. It is designed to be steamed to fix the dye. The discharged steam moves to the inlet port 1) and the outlet port 12 which are open, and is discharged to the outside of the casing 3 along with the air degassed from the sliver 5. In this way, in the second casing 3, the inlet 1) and the outlet 12 also serve as a deaeration port.

As the far-infrared heater 9 provided in the first casing 2, for example, a far-infrared ceramic heater (manufactured by Noritake Co., Ltd.) shown in FIG. 2 can be mentioned. This far-infrared heater 9 has a sheathed heater body 15 covered with a ceramic pipe 16, and has excellent corrosion resistance, heat resistance, insulation, etc., and is suitable for use in a dyeing process.

Such a far-infrared heater 9 improves heat penetration, absorption, and
Excellent direct heating properties by radiation.

In the above embodiment, the far-infrared heater 9 and the net conveyor 8 are arranged in an upwardly inclined manner (see Fig. 1), but this improves the efficiency of the inside of the sliver 5 being conveyed as described above. The inclination angle is preferably set to 30 to 60 degrees so that discharged steam can enter from below. Depending on the above-mentioned inclination angle, the conveyance of the first sliver 5 may slip and fail at the start of work, but in such a case, insert your hand through the inlet 6 and transfer the tip of the sliver 5 to the net conveyor 8. Conveyance may be started by tying a string lightly on the surface, and after the knot is released by the discharge lower, continuous conveyance can be performed.

Further, the second casing 3 and the steam discharge port 13 are
- It does not have to be box-shaped; it may be of any type, such as a normal high-pressure steamer used in batch 2. For example, as an alternative to the J-box type, a steamer as shown in FIG. 26 can be cited.

This steam heating device includes a first con-hair 120 that is arranged to be inclined to form a downward slope with respect to the downstream side, and a first conhair 120 that is arranged to be inclined upwardly or to form a horizontal plane with respect to the downstream side. Two conveyors 121 are used in combination, and the conveyance speed of the first conveyor 120 is higher than that of the second conveyor 120.
Since the conveyance speed is set to be faster than the conveyance speed of the conveyor 121, it is devised so that the sliver 53 introduced by shaking off is conveyed as a folded layer tilted backward (upstream side) on the conveyor. It is something that

Therefore, only the weight of that part is added to the folded part of the sliver 5a, and the weight of the entire other folded groups stacked on top of it is added to the folded part of the sliver 5a.
without destroying the lamination or creating creases,
It is easy to take out the sliver from the takeout port 126,
This prevents the slivers from getting entangled with each other, which tends to occur with the conventional J-box type. In addition, 122 is a casing, 123 is a sliver introduction port, 124 is a sliver shaking-off mechanism, and 125 is a steam discharge port.

Next, the process of fixing the dye on the sliver 5 using the dye fixing device 1 will be explained.

FIG. 3 shows a step in which the dye fixing device 1 is connected to a boat-type Vigoro printing device 20 to continuously print the sliver 5 and fix the dye. In the figure, the sliver 5 is pulled out from a plurality of cans 21, aligned in parallel by a rotating roll 22, and becomes a sheet-like sliver 5 by passing through a gill 23. When this sheet-like sliver 5 passes between the felt roll 24 and the engraving roll 25° 25', it is supplied with printing paste supplied from the printing paste supply roll 27 partially immersed in the printing paste box 26. , the printing paste is retained on the surface and inside of the sliver 5. The printing paste is applied to the sliver 5 using an engraving roll 25 (25') as shown in FIG.
A spiral protrusion 28 carved on the outer peripheral surface of the sliver 5
This is done by pressing the felt roll 24 impregnated with printing paste through the printing paste. 29 is the spiral protrusion 28
This is a diagonal striped pattern formed by partially applying printing paste to the sliver 5 by pressing. In this state, the printing paste is only attached to the surface of the sliver 5 and between the fibers, and the dye contained in the printing paste and the fibers of the sliver 5 are not chemically bonded at all. Next, the sliver 5 to which the printing paste has been applied in a diagonal striped pattern is continuously introduced into the first casing 2 of the dye fixing device 1 (return to FIG. 3). The above-mentioned continuous introduction is performed by passing the sliver 5 between two opposing rotating rolls 30 at an inlet 6 provided in the first casing 2 and conveying it by a net conveyor 8.

During the conveyance process, the sliver 5 is transferred to the far-infrared cotton heater 9 in the upper and lower heater blocks of the net conveyor 8.
receives far-infrared heating. During this time, steam is constantly being discharged from the steam discharge port 10 provided at the bottom of the first casing 2 in the direction of the far-infrared heater 9, and most of the discharged steam is transferred to the net conveyor. It flows from the bottom to the top inside the first casing 2 along the ascending slope 8 . By this steam flow and far-infrared heating from the far-infrared heater 9, the air contained inside the fibers of the sliver 5 is replaced with steam and expelled from the sliver 5, and the sliver 5 is sufficiently heated to the inside. will be done. Next, the sliver 5 that has passed through the space in which the far-infrared heater 9 is provided is conveyed to the discharge lower of the first casing 2 and sequentially falls from there. The falling sliver 5 is guided by a guide plate 3 that swings from side to side.
1 without getting tangled, and in that state it is introduced into the inlet 1) of the second casing 3, and due to its own weight and the tension mechanism provided on the outlet 12 side of the second casing 3 (Fig. (not shown) passes through the inside of the casing 3 in a folded state. During this passage, the dye of the sliver 5 is steamed by the steam discharged from the steam discharge port 13, and a chemical bond is formed between the dye and the fiber, and the dye is fixed to the fiber. In this case, the sliver 5 is attached to the casing 3 for sufficient time for the dye fixation reaction to be completed.
It moves inside to the discharge port 12 on the downstream side, and is taken out from the discharge port 12 to the outside of the casing 3 via the rotating roll 32.

Following this process, wool slivers (2
5 g/m) was printed and dye fixation was performed.

It was a minute. In addition, the preheating conditions in the first casing 2 were such that the heating medium temperature of the far infrared heater was 130° C., the saturated steam atmosphere was set, the time for the sliver 5 to pass through the first casing 2 was 1 minute, and the second casing 2 was heated for 1 minute. Passing time within 3 is 20
A dye-fixed product (required time for research: 21 minutes) was obtained in minutes.

As a comparative example, the sliver 5 was directly introduced into the second casing 3 after printing without using the first casing 2, and the passage time in the second casing 3 was set to 40 minutes. A dye-fixed product (required time for Soken: 40 minutes) was obtained in the same manner as above except for the above.

After washing the experimental and comparison products obtained in this way with a back washer,
The dye fastness was examined for the items shown in the table. The results are shown in Table 1. Note that each test was conducted in accordance with the JIS test method.

Table 1 (Grade) From the results in Table 1, there is no difference in color fastness between the tested products and the comparative products.
It can be seen that the previously required time can be reduced to 21 minutes, resulting in a significant improvement in operational efficiency.

Next, according to the above steps, polyethylene sliver (
25 g/m) was printed and dye fixation was performed.

The printing paste used for printing is a mixture of the following raw materials.

800〃In this test, the preheating conditions in the first casing 2 were as follows: the heating medium temperature of the far-infrared heater was 210'C, the saturated steam atmosphere was set, and the time for the sliver 5 to pass through the first casing 2 was 210'C. It was a minute.

Other than that, the dye-fixed product (
Total research time required: 22 minutes).

As a comparative example, the sliver 5 was introduced into a conventionally used high-pressure steamer after printing without using the first casing 2,
The passage time in the high pressure steamer was 40 minutes. Other than that, the dye-fixed product was carried out in the same manner as the above test (required time for Souken: 40 minutes).
I got it.

Regarding the actual product and comparative product obtained in this way,
After single-source cleaning and pack washer cleaning,
The dye fastness was examined for the items shown in Table 2 below. The results are shown in Table 2. The testing method is the same as in Table 1.

Knee 1 (Grade) From the results in Table 2, there is no difference in dyeing fastness between the tested products and the comparative products. Therefore, according to the present invention, the dyeing fastness is good not only for natural fiber slivers but also for synthetic fiber slivers. It can be seen that an excellent time shortening effect (40 minutes to 22 minutes) can be obtained.

In addition, in the above dyeing example of polyethylene sliver, it is not necessarily necessary to pass the polyethylene sliver through the second casing 3, and good results can be obtained only by thermosol dyeing within the first casing 2.

The dye fixing device of the present invention can also be connected to a textile coloring device that performs special dyeing. This will be explained using FIG. 5. FIG. 5 shows an example in which the dye fixing device 1 of the present invention is connected to the above-mentioned special textile coloring device.

In this textile coloring device 40, the sliver 5 taken out from a plurality of cans 21 is arranged in parallel with a rotating roll 22 to form a sheet, and then the sliver 5 is processed into a sheet by three sets of special printing units U each equipped with an upper and lower pair of drums. This is a device that performs multicolor printing by passing it between drums. In the figure, 41 is a base;
Reference numeral 2 denotes a feed rate control means for controlling the feed rate of the sliver 5. The feed speed control means 42 operates so that the sliver 5 sent out from the can 21 is fed into the printing unit U at an appropriate speed. Further, 43 is a feed roll that feeds the sliver 5 before printing into the printing unit U in an aligned state, and 44 is a feed roll that sends out the printed textile product, both of which are designed to rotate freely. .

The above-mentioned textile printing unit U will be explained in detail with reference to FIG. 6, which is a perspective view of its appearance, and FIG. 7, which is a longitudinal sectional view thereof. In these figures, reference numeral 45 denotes a pair of left and right metal frames, on which a stainless steel hollow drum 46 for discharging a colored liquid and a hollow drum 47 for sucking a colored liquid are vertically and oppositely arranged in a fixed state. There is. Both drums above 46.47
As shown in FIG. 7, slit-shaped communication holes 48 and 49 extending in the axial direction are bored in the opposing portions of the two.

A colored liquid outflow sleeve 50 and a colored liquid suction sleeve 51 made of stainless steel are rotatably fitted around the outer peripheries of the colored liquid outflow hollow drum 46 and the colored liquid suction hollow drum 47, respectively. Sleeve 50.51
A plurality of slits 52 and 53 having the same shape as the slit-like communication holes 48 and 49 are formed at equal intervals in the circumferential direction on the outer circumferential surface of the slit. The colored liquid outflow sleeve 50 and the colored liquid suction sleeve 51 each have gears 54 and 55 that fit with each other, and the colored liquid suction sleeve 51
A gear 55 provided on the rotary shaft 57 of the motor 56 meshes with a gear 58 provided on the rotating shaft 57 of the motor 56 to be rotationally driven by the motor 56.

As a result, both the sleeves 50, 51 open the plurality of slits 52, 53 provided on their respective outer peripheral surfaces at the same timing to the communication holes 48, 4 of the hollow drums 46, 47.
9 in order.

The colored liquid outflow hollow drum 46 and the colored liquid suction hollow drum 47 are fixed to main shafts 59 and 60, respectively.The main shaft 59 is fixed to a shaft holder 61 of the frame 45, and the main shaft 60 is fixed to the frame 45. Fixed. Both sleeves 50.51 fitted around the outer peripheries of the two hollow drums 46.47 are attached to this main shaft 59.60 via bearings and rotate around the outer peripheries of the two hollow drums 46.47. Main shaft 5 of the hollow drum 46 for colored liquid outflow
9 has a hollow interior, into which a colored liquid mainly composed of dyes, pigments, etc. is supplied via a vibro 2 with a liquid pump (not shown); Also,
The main shaft 60 of the colored liquid suction hollow drum 47 is also hollow inside, and is connected to a vacuum pump (
(not shown). As shown in FIG. 7, holes 64.
65 is provided, the colored liquid sent through the vibro 2 flows down from the hole 64 of the main shaft 59 into the hollow drum 46 for flowing out the colored liquid, and this flowing liquid is transferred to the above-mentioned Surin 1-
52, 53 and the communication holes 48° and 49, the suction force of the vacuum pump causes the liquid to be fed into the hollow drum 47 for suctioning the colored liquid via the communication hole 48 - slit 52 - slit 53 → the communication hole 49, and then through the holes. 65 into the main shaft 60, and from there it is discharged to the outside via the vibro 3. This discharged liquid is replenished with colorant as appropriate and is again supplied from the colored liquid outflow hollow drum 46. In addition, 64゛ raises and lowers the shaft holder 61 and both sleeves 50.5
It is a body with an adjustment handle that adjusts the gap between the holes.

Dyeing by the textile coloring device 40 combined with such a drum unit U is performed by rotating the motor 56 to drive the gears 54 and 55. This is done by passing the sliver 5 between the two sleeves 50, 51 (FIG. 8). In this case, each sliver 5
Each maintains a large string-like shape until it enters between the sleeves 50 and 51, but is formed into a substantially flat sheet shape by the pressure applied when passing between the sleeves 50 and 51,
When the slits 52, 53 of the sleeves 50, 51 respectively match the flow holes 48, 49 of the hollow drums 46 and 47, the dye liquid is suctioned and passed through, and the sliver 5 is forcibly colored in a striped pattern. It turns out. In this case, the spacing of the striped patterns substantially matches the spacing in the circumferential direction of the sleeves 52, 53 in both sleeves 50, 51.

In this way, the sliver 5 becomes a set of drum units)
A striped colored material of one color is obtained by passing through the drum unit U, and the color of the dye solution is further changed by passing through another drum unit U in which the phase of drum rotation is shifted.
A colored liquid with a multicolored striped pattern as shown in the figure is obtained. In the figure, in the first drum unit U, II? I pattern a is
The second drum unit U has a striped pattern, while the third drum unit U has a striped pattern C.

As described above, according to this textile coloring device 40, the coloring liquid is forcibly passed through the sliver 5 by the negative pressure in the hollow drum 47 for coloring liquid suction, so that the sliver 5 can be colored even if the sliver 5 is thick. However, it is easy to uniformly color the inside. Therefore, this textile coloring device 40
It can be said that the colored fiber products obtained by this method are extremely thick and have a large air content and dye liquid content compared to printed products obtained by conventional printing or the like. Therefore, if the dye fixation is carried out as described above using the dye fixing device 1, the dye fixation can be carried out in an extremely short time, and production efficiency can be significantly improved.

Note that the above-mentioned textile coloring device 40 is a special textile coloring device in which the dye solution is forced to pass through the sliver.
However, various types can be used.

For example, it is possible to use a hollow drum for discharging the colored liquid shown in FIG. 10 in which a sleeve is not fitted onto the outside of the drum. That is, in this drum unit, a plurality of grooves 72 having colored liquid flow holes 71 at the bottom of the grooves are formed at predetermined intervals in the circumferential direction on the outer peripheral surface of the colored liquid outflow drum 70. 1) As shown in the figure, a slit plate block 75 has a plurality of long slit plates 73 made of stainless steel arranged side by side, and short partition plates 74 made of stainless steel erected thereon at predetermined intervals. The slit plate 73 is inserted and fixed with the side of the slit plate 73 facing inside and the longitudinal direction of the slit plate 73 aligned with the longitudinal direction of the groove 72. Of the plurality of slit plates 73, both left and right sides 73a and 73e
and slit plates 73b other than the central slit plate 73c,
73d includes the circled part B in FIG. 12 (first).
As shown in the enlarged view of FIG. . The slit plate 73 and the partition plate 74 have an alkali treatment to remove surface oils and a subsequent acid treatment to form irregularities on the surface to increase their affinity for water. 73 and the partition plate 74.Other than that, the drum unit is the same as the drum unit shown in FIG. 7, and the operation and effect are also the same.

Also, instead of the slit plate block 75, the strip 'a7
A drum unit (Fig. 13) in which a porous material 80 having continuous pores such as polyvinyl formal sponge is inserted and fixed, and a T8 aqueous flocculent material 81 is stretched over the entire opening of the groove 72. drum unit (14th
Figure) may also be used. Like the slit plate block 75, the porous body 80 and the tn aqueous network body 81 have a retention function for the colored liquid. Note that FIG. 15 shows a state in which the water-repellent network body 81 retains the colored liquid 82.

Furthermore, not only the hollow drum for discharging the colored liquid but also the hollow drum for sucking the colored liquid may be of a type in which a sleeve is not fitted onto the outside. For example, in the drum unit shown in FIG. 16, the main shaft 5 of the hollow drum 70 for discharging the colored liquid
A nozzle 83 for discharging a colored liquid is fitted into the flow hole 64 of 9, and a main shaft 85 of a hollow drum 84 for suctioning the colored liquid
It is the axis of peeling. Similar to the drum unit shown in FIG. 10, a slit plate block 75 is fitted and fixed in the groove 72 on the outer peripheral surface of the hollow drum 70 for discharging the colored liquid. - On the other hand, the hollow drum for colored liquid suction has drums 84 on its outer peripheral surface at predetermined intervals in the circumferential direction.
A groove 87 is formed as a pair with a communicating path 86 which is open at one end surface. The groove 87 has a porous body 8
8 is fitted and fixed, and a vacuum pump (
(not shown) causes the colored liquid to be absorbed into the porous body 8.
8 - communication hole 90 - communication path 86 - pipe 89 to be discharged to the outside of the drum 84. Incidentally, FIG. 17 is a sectional view showing the state in which the textile article 91 passes through this drum unit. In the figure, the colored liquid flows down inside the textile product 91 as indicated by arrow A.

In addition, the hollow drum 84 for colored suction (see Fig. 16)
Instead of forcibly suctioning the colored liquid from the side, the 18th
The colored liquid may be forcibly discharged from the colored liquid outflow hollow drum 92 side as shown in the figure. That is,
In this drum unit, main shafts 93 and 94 are used as bare shafts, and a hollow drum 92 for discharging the colored liquid is provided with communicating passages 93 and 92 opened at one end surface of the drum 92, respectively, at predetermined intervals in the circumferential direction on the outer peripheral surface thereof. Paired row'f#9
4 is used. A porous body 96 is fitted and fixed in the groove 94 to hold a colored liquid injected through a pipe 95 on the upper end side of the drum 92, which communicates with the communication path 93' by sequentially aligning with the communication path 93'. There is. −
On the other hand, a pipe 97 is provided on the lower end side of the drum 92 so as to sequentially match and communicate with the communication path 93'', and compressed air is supplied to this pipe 97 by a compression pump (not shown). The compressed air is supplied by the compression pump through a cam switch 98 (19th
Control is performed so that communication is performed every time the communication path 93'' of the drum 92 and the pipe 97 match and communicate by the action of a solenoid valve 99 which is opened and closed by a solenoid valve 99 (see figure).
The colored liquid injected at the upper end of the drum 92 and held in the porous body 96 is forcibly discharged downward (to the colored suction hollow drum) at the lower end of the drum 92 by the supply of compressed air. The colored liquid suction hollow drum 100 in this drum unit is composed of a pair of left and right disc-shaped side plates 101 and a cylindrical stainless steel mesh 102 installed between both side plates. The discharged colored liquid is passed through the mesh of the stainless steel mesh 102 to be discharged below the drum 100.

Furthermore, the forcible discharge of the colored liquid from the lower end side of the colored liquid outflow hollow drum 92 (see FIG. 18) is stopped,
The colored liquid may be forcibly sucked from the colored liquid suction hollow drum side. As the colored liquid suction hollow drum, for example, the colored liquid suction hollow drum 84 of the drum unit shown in FIG. 16 can be used. Such a drum unit is shown in FIG. That is, in this drum unit, the porous body 9 is disposed on the upper end side of the hollow drum 92 for discharging the colored liquid in the same way as the drum unit shown in FIG.
After the colored liquid is injected into and held in the colored liquid injected into the coloring liquid 6, the colored liquid injected porous body 96 faces the colored liquid suction drum 84 at the lower end side of the drum 92. The colored liquid suction drum 84 is a first
As already mentioned in the explanation of the six drum units, the colored liquid on the side of the colored liquid outflow drum 92 is transferred to the porous body 88.
Since the suction is carried out through the path of - communication hole 90 - communication path 86 - pipe 89, the colored liquid held in the porous body 96 of the colored liquid outflow hollow drum 92 is transferred to the colored liquid suction drum 84. is sucked into the porous body 88.

Furthermore, a piston pump 103 for liquid feeding is connected to the main shaft 59 of the drum unit shown in FIG. 13 via a vibro 2, and the colored liquid is quantitatively inserted into the hollow drum 70 for flowing out the colored liquid. (Figure 21). In the figure, 104 is a piston rod of a piston pump 103, and 105 is a crankshaft for driving the piston rod 104. This crankshaft 105 is given rotation by gears 106 and 107 that mesh with gears that rotationally drive both drums 51 and 70 of the drum unit, and the piston pump 103 is rotated in synchronization with the rotation of both drums 51 and 70. drive

Furthermore, as an application of the drum unit shown in FIG.
8,109, which is inserted into the hollow drum 70 for coloring liquid distribution is also used (FIG. 22). This drum unit has almost the same liquid feeding mechanism as the drum unit shown in FIG. 21 above, but is characterized by two colored liquid flow paths (1)0. ,
Textiles can be colored in alternating stripes of two colors in a single drum unit. That is, the two types of colored liquids inserted into the colored liquid outflow hollow drum through the two flow paths 1)0 and 1)1 are passed through the nozzles 1)2 and 1)3 as shown in FIG. What, article? ! When j72 is located directly below, it is alternately discharged downward. Therefore, the porous bodies 80 fitted and fixed in the respective grooves 72 alternately hold different colored liquids and color the textile article in a striped pattern of two colors alternating. Note that 1) 4 is a partition plate for separating not only the groove 72 directly below but also the grooves 72a and 72b on both sides so that the discharged colored liquid does not contaminate the grooves 72a and 72b.

In these various drum units, the grooves are not formed parallel to the axial direction as described above (the grooves are formed parallel to the axial direction).
As shown in FIG. 4, it may be formed in an axially inclined state. Further, as shown in FIG. 25, a plurality of holes may be provided in a continuous manner instead of the grooves.

These devices are suitable for being connected to the dye fixing device 1 of the present invention because they are capable of uniformly printing even thicker materials than normal Vigoro printing devices.

〔Effect of the invention〕

As described above, the dye fixing device of the present invention performs efficient preheating and degassing by combining far-infrared heating and steam heat using a far-infrared heater before starting the full-scale steaming process. Therefore, even thick materials can be sufficiently heated and degassed to the inside quickly, and the time required for the subsequent full-scale steaming process can be significantly shortened. Therefore, dye fixing using the dye fixing device of the present invention is excellent with extremely high production efficiency.
