Description

  The present invention relates to a carpet continuous dyeing machine capable of expressing various color patterns.

In general, a color pattern of a carpet is expressed by post-dying by dyeing a pile yarn of a living machine by a continuous dyeing machine, an inkjet printing machine, or the like.
The continuous dyeing | staining method dye | stains using a continuous dyeing machine is a method of dyeing a living machine in the middle of conveying a living machine to a longitudinal direction. In the continuous dyeing method, the so-called "shower curtain type" in which dye is discharged from a plurality of nozzles arranged in the width direction of the raw machine to the surface of the raw machine to be conveyed, and the raw machine is soaked in the dyeing liquid, The dyeing process is continuously performed using a so-called “dipping type” or the like. Such a conventional continuous dyeing machine can dye a large amount of raw machinery by using only a single kind of dye or using an acid dye and a cationic dye in combination, and is excellent in carpet productivity.
However, the continuous dyeing machine has a limit in the expression of the color pattern, and it is difficult to obtain carpets with various color patterns even when the acid dye and the cationic dye are used in combination as described above.

On the other hand, an ink jet method using an ink jet printing machine is a method of dyeing a living machine by spraying a dye from a printer head in the form of a mist, and can express a delicate color pattern (Patent Document 1).
However, the inkjet printing machine has a problem that printing speed is relatively slow and carpet productivity is poor. Further, since the dye is ejected in accordance with a predetermined pattern, only a predetermined color pattern can be expressed, and it is difficult to obtain a natural-toned carpet with a natural feeling that the dye has oozed out.

<Conveyor>
The conveying apparatus 3 conveys the long strip-shaped raw machine B in the longitudinal direction. The white arrow in each figure shows the conveyance direction of the living machine B. The conveying device 3 includes a conventionally known roller and a driving device (not shown). The raw machine B transported by the transport device 3 is an undyed live machine. The undyed living machine B has a long belt-like base fabric and undyed pile yarn tufted on the base fabric.
The undyed green machine B is a green machine before dyeing pile yarn using a dye to obtain a final carpet design. Therefore, as will be described later, the undyed living machine B includes not only a case where the pile yarn is not dyed at all, but also a case where the pile yarn is dyed in some color.
In the present specification, the side to which the living machine or the like is sent is referred to as “downstream side”, and the opposite side is referred to as “upstream side”.

<Pre-processing section>
The pretreatment unit 4 is a device that applies a treatment agent to the surface of the undyed living machine B. The surface of the living machine B is made of pile yarn.
The treating agent contains at least one of a dye-resisting agent and water, and may contain other components as necessary. Examples of other components include a viscosity adjusting agent such as a paste, a pH adjusting agent, a dye, and a leveling agent. Details of the treating agent will be described in detail in the section of the continuous dyeing method.

The said processing agent is apply | coated to the surface of the raw machine B using the suitable pre-processing part 4. FIG.
The pre-processing part 4 will not be specifically limited if a processing agent can be apply | coated to the surface of the raw machine B conveyed by the said conveying apparatus 3. FIG. In the illustrated example, a roll 41 that rotates in synchronization with the transport of the living machine B is used as the preprocessing unit 4. One roll 41 may be provided, or a plurality of rolls 41 may be provided in parallel. In the illustrated example, two rolls 411 and 412 (a first roll 411 and a second roll 412) are arranged in parallel to each other in the conveying direction of the living machine B.
The roll 41 (the first roll 411 and the second roll 412) has an axis arranged substantially parallel to the width direction of the living machine B, and can rotate around the axis. The roll 41 may be rotated by a driving force applied by a separate driving device (not shown). Alternatively, the roll 41 may be rotatably supported on a shaft while being in contact with the surface of the raw machine B, and may be rotated following the conveyance of the raw machine B.

On the peripheral surface of the roll 41, an application part (not shown) provided with a treatment agent is provided.
For example, a printing method can be used as the application unit using the roll 41.
Specifically, (1) a roll having a convex portion formed on the peripheral surface is used, a processing agent is attached to the top surface of the convex portion from a separate processing agent supply roll, and the convexity of the peripheral surface is determined according to the rotation of the roll. A method of applying a treating agent to the living machine B by bringing the top surface of the part into contact with the surface of the living machine B (use of relief printing method), (2) Separate processing using a roll having a recess formed on the peripheral surface A method of applying the treatment agent to the living machine B by filling the recess into the recess from an agent supply roll or the like and bringing the recess of the peripheral surface into contact with the surface of the living machine B according to the rotation of the roll (use of intaglio printing method) ), (3) Using a roll having innumerable fine holes formed on the peripheral surface, supplying the treatment agent from the inside of the roll, bringing the peripheral surface into contact with the surface of the living machine B according to the rotation of the roll, and finely treating the treatment agent Method of exuding from the hole and applying to the machine B (the advantage of the stencil printing method) ), And the like.
When the rolls 41 of (1) and (2) are used, the treatment agent is transferred to the living machine B in substantially the same shape as the plan view of the convex and concave portions. When the roll 41 of the above (3) is used, the treatment agent is transferred to the living machine B in substantially the same shape as the aggregate shape of innumerable fine holes.
Since the coating amount per time is large, it is preferable to use the roll 41 of the above (3). In particular, by using the roll 41 of the above (3) that can apply a relatively large amount of the processing agent, the processing agent containing a large amount of water is applied to sufficiently dilute the staining agent in the downstream dyeing portion 5. Therefore, it is possible to display a good gradation color pattern.

Depending on the form of the application part of the roll 41, the application shape of the treatment agent can be set as appropriate.
For example, when the roll 41 having a spot-like application portion provided on the peripheral surface is used, the treatment agent C is spot-like in plan view with a predetermined interval in the longitudinal direction on the surface of the living machine B. It is applied to the shape. The spot-like shape is not particularly limited, and examples include a substantially polygonal shape such as a substantially rectangular shape and a substantially triangular shape, a substantially circular shape, a substantially elliptical shape, a substantially star shape, and other arbitrary shapes. In this case, only one spot-shaped application portion such as a substantially rectangular shape may be provided in the circumferential direction on the circumferential surface of the roll 41, or a plurality of spots may be provided at predetermined intervals in the circumferential direction. It may be. Further, only one spot-shaped application portion may be provided on the peripheral surface of the roll 41 in the axial direction, or a plurality of application portions may be provided at predetermined intervals in the axial direction. .

Moreover, for example, when the roll 41 in which the coating part having a continuous shape over the entire circumferential direction is provided on the circumferential surface of the roll 41, the treatment agent C is flat on the surface of the living machine B in the longitudinal direction. It is applied in the shape of a visual band. Examples of the continuous shape include an annular shape extending over the entire circumferential direction of the peripheral surface. In this case, only one coating portion having a continuous shape in the circumferential direction may be provided on the circumferential surface of the roll 41 in the axial direction, or on the circumferential surface of the roll 41, the coating portion may be provided in the axial direction. A plurality may be provided at intervals.
Furthermore, the spot-shaped application part and the continuous-shaped application part may be provided on the peripheral surface of the roll 41. In addition, the form of the application part provided in the roll 41 can be variously set.

As described above, when a plurality of rolls 41 are arranged in parallel (for example, the first roll 411 and the second roll 412), the form of the application part of each roll 41 may be the same or different. From the significance of using a plurality of rolls 41, it is preferable to use a plurality of rolls 41 having different forms of application portions.
For example, the first roll 411 is provided with a plurality of spot-like application portions such as a substantially rectangular shape, and the second roll 412 is provided with a continuous application portion.

<Dyeing part>
3 to 5, a staining unit 5 is provided on the downstream side of the pretreatment unit 4.
The dyeing unit 5 is a device that applies a dyeing agent to the surface of the undyed living machine B. The form of the dyeing agent coating apparatus is not particularly limited, and examples thereof include a shower curtain type and a dipping type. The shower curtain type is a device that performs dyeing by pouring and applying an appropriate amount of dyeing agent onto the living machine B from above, and the dipping type allows the living machine B to be hidden in the dyeing tank in which the dyeing agent is stored. Is a device for dyeing. Since there is no possibility that the treatment agent applied to the living machine B in the pretreatment unit 4 flows out, the amount of dyeing can be controlled, and it is excellent in homogenizing dyeing and controlling the dyeing speed. preferable.
In the example of illustration, the shower curtain type application part 5 is shown.
As shown in FIGS. 4 to 8, the dyeing unit 5 is disposed between the plurality of discharge ports 51 and the living machine B and the plurality of discharge ports 51, and the dyeing agent discharged from the discharge ports 51 is the living machine B. And an adjusting unit 53 that adjusts the discharge amount of the stain from each discharge port 51, and preferably measures the discharge amount of the stain flowing out from each discharge port 51. The flow meter 54 is further provided.

A guide plate 52 is disposed in the middle of the transport device 3 and immediately downstream of the pretreatment unit 4. The guide plate 52 is formed of a plate-like body having a flat surface. In the illustrated example, the guide plate 52 has a substantially rectangular shape in plan view. The back surface of the guide plate 52 may be flat or formed in an uneven shape. The guide plate 52 is not limited to a flat plate, and a plate-like body having a bent portion or a plate-like body having a curved surface portion may be used. Further, the lower end 521 of the guide plate 52 is preferably pointed in side view as shown in FIGS. 5 and 8. Since the lower end 521 of the guide plate 52 is pointed in a side view, the cutting of the stain is improved, and the stain that has flowed on the surface of the guide plate 52 does not easily go around the back side of the guide plate 52.
The material of the induction | guidance | derivation board 52 is not specifically limited, A metal, a synthetic resin, glass, earthenware, these combinations etc. are mentioned. Among them, it is preferable that the guide plate 52 is made of stainless steel because it is excellent in corrosion resistance and hardly adheres to the stain.

The guide plate 52 is disposed on the surface of the living machine B transported by the transport device 3. The guide plate 52 is arranged with the lower end 521 of the guide plate 52 substantially parallel to the width direction of the living machine B so as to extend in the width direction of the living machine B.
As shown in FIG. 8, the guide plate 52 is fixed to a fixed side (not shown) with its lower end 521 away from the surface of the living machine B. Further, a moving device (not shown) for moving the guide plate 52 up and down may be provided so that the lower end 521 of the guide plate 52 can be moved closer to or away from the surface of the living machine B.
The lower end 521 of the guide plate 52 in the illustrated example is linear in plan view. However, the lower end 521 of the guide plate 52 has a wavy shape, a zigzag shape, an arc shape or a bent shape in which the central portion in the width direction is recessed inward, or an arc shape or a bent shape in which the central portion in the width direction protrudes to the outside. May be.

When the lower end 521 of the guide plate 52 is away from the living machine B, the straight line length H1 between the lower end 521 of the guide plate 52 and the surface of the living machine B is not particularly limited. If it is too large, the size of the apparatus will be increased, and the stain flowing down from the lower end 521 of the guide plate 52 may be rebounded on the surface of the living machine B. From this point of view, it is preferable that the guide plate 52 is disposed so that the linear length H1 between the lower end 521 of the guide plate 52 and the surface of the living machine B is 5 mm to 100 mm, so as to be 10 mm to 50 mm. More preferably, the guide plate 52 is disposed.
In addition, when the moving apparatus which moves the above-mentioned guide plate 52 up and down is provided, it becomes possible to finely adjust the said linear length H1 to an appropriate distance according to manufacturing conditions, an environment, etc.

As shown in FIGS. 4 and 7, the length in the width direction of the guide plate 52 is larger than the width of the raw machine B transported by the transport device 3. It protrudes outward from both ends in the width direction.
Further, as shown in FIG. 8, the length L1 of the guide plate 52 (the length of the guide plate 52 corresponding to the longitudinal direction of the living machine B) is not particularly limited, but if it is too small, the area through which the dyeing agent is transmitted is large. May be too small. From this point of view, the length L1 of the guide plate 52 is preferably 100 mm or more, and more preferably 200 mm or more. Further, if the length L1 of the guide plate 52 is too large, the apparatus is increased in size, and therefore the length L1 of the guide plate 52 is preferably 500 mm or less.

As shown in FIG. 8 and the like, the guide plate 52 is disposed so that the lower end 521 of the guide plate 52 is lower than the upper end 522 in a side view and the surface thereof is non-parallel to the surface of the living machine B. Yes. Preferably, the guide plate 52 is disposed such that the inner angle α formed by the surface of the guide plate 52 and the surface of the living machine B is greater than 0 degree and equal to or less than 90 degrees, and more preferably, the inner angle α is 10 degrees to The guide plate 52 is disposed so as to be 80 degrees, and more preferably, the guide plate 52 is disposed so that the inner angle α is 30 degrees to 70 degrees. Since the guide plate 52 is disposed at an acute angle with respect to the living machine B as described above, the staining agent flows favorably from the surface of the guide plate 52 to the surface of the living machine B.
However, the internal angle α formed by the surface of the guide plate 52 and the surface of the living machine B when the guide plate 52 has a shape having a bent part or a curved part is an average angle.
In addition, an angle adjusting device (not shown) may be provided on the guide plate 52 so that the inner angle α can be changed. If the inner angle α is reduced, the staining agent is more easily mixed. If the inner angle α is increased, the staining agent is less likely to be mixed. By adjusting the internal angle α (inclination angle) of the guide plate 52 by providing an angle adjusting device, the degree of mixing due to differences in conditions such as the type of dye and the viscosity can be stabilized, or according to the desired color pattern You can adjust the width of the blur area.

  Further, a vibration device (not shown) that vibrates the guide plate 52 may be provided. The vibration device vibrates the guide plate 52 in parallel with the width direction of the living machine, moves the guide plate 52 in parallel with the longitudinal direction of the living machine, and moves the guide plate 52 closer to or away from the living machine. It has at least 1 operation | movement chosen from the operation | movement which vibrates in an up-down direction. When the guide plate 52 vibrates, it is possible to change the way the stain is mixed on the guide plate 52. If the vibration width of the guide plate 52 by the vibration device is too small, there is substantially no effect of vibration, and if it is too large, the stain may leak from the guide plate 52 greatly. From this viewpoint, the vibration width of the guide plate 52 is preferably about 0.3 mm to 10 mm.

A plurality of discharge ports 51 are arranged on the surface of the guide plate 52. The plurality of discharge ports 51 discharge the stain independently of each other. Each discharge port 51 is an outlet of a stain supplied from a tank described later, and each discharge port 51 discharges the stain onto the surface of the guide plate 52. Such a discharge port 51 is generally called a nozzle, and a conventionally known one can be used as the discharge port 51.
The material of the discharge port 51 is not particularly limited, and examples thereof include metals and synthetic resins. Among these, the discharge port 51 is preferably formed of stainless steel because it is excellent in corrosion resistance and hardly adheres to the stain. The diameter of the discharge port 51 is not particularly limited, and is, for example, about 3 mm to 40 mm.

As shown in FIG. 6 and FIG. 7 and the like, the plurality of discharge ports 51 are arranged on the surface of the guide plate 52 side by side in the width direction of the raw machine B before being dyed conveyed to the conveying device 3. . The discharge ports 51 are arranged in a straight line in the width direction of the living machine B. In the illustrated example, the discharge ports 51 are arranged in a line, but the discharge ports 51 may be arranged in two or more rows in the longitudinal direction of the living machine B as shown in FIG. .
The interval W1 between the adjacent ejection ports 51 is not particularly limited, and is, for example, 5 mm to 100 mm, preferably 10 mm to 60 mm. If the interval W1 is too large, fine expression becomes difficult. If the interval W1 is too small, the apparatus becomes complicated and it may be difficult to discharge the staining agent. The number of the discharge ports 51 can be appropriately set according to the length in the width direction of the living machine B and the interval between the discharge ports 51. It should be noted that although there are ten discharge ports 51 in the illustrated example, this number is shown schematically.

Each discharge port 51 is fixed to a fixed side (not shown) apart from the surface of the guide plate 52. However, the discharge port 51 may be fixed so as to contact the surface of the guide plate 52.
When each discharge port 51 is away from the guide plate 52, the linear length H2 between each discharge port 51 and the surface of the guide plate 52 is not particularly limited, but if it is too small, they are in contact with each other and are too large. In addition, the size of the apparatus is increased, and the stain discharged from the discharge port 51 may rebound on the surface of the guide plate 52. From this point of view, the straight line length H2 between each discharge port 51 and the surface of the guide plate 52 (the straight line length drawn in the vertical direction from the discharge port 51 to the surface of the guide plate 52) exceeds 0 and is 60 mm or less. It is preferable that each discharge port 51 is disposed so as to be, and it is more preferable that each discharge port 51 is disposed so as to be 10 mm to 40 mm.

Each discharge port 51 is disposed correspondingly between the lower end 521 and the upper end 522 of the guide plate 52. The straight line length L2 from each discharge port 51 to the lower end 521 of the guide plate 52 is not particularly limited, but if each discharge port 51 is too close to the lower end 521 of the guide plate 52, the stain is applied on the surface of the guide plate 52. The flowing distance is relatively small. From this point of view, it is preferable that each discharge port 51 is arranged so that the linear length L2 from each discharge port 51 to the lower end 521 of the guide plate 52 is 50 mm to 500 mm, and each 100 mm to 400 mm. It is more preferable that the discharge port 51 is arranged.
Further, each discharge port 51 is moved up and down so that each discharge port 51 can approach or move away from the surface of the guide plate 52 and / or each discharge port 51 can move closer to or away from the lower end 521 of the guide plate 52. A moving device (not shown) may be provided. By providing such a moving device, it is possible to adjust the degree of mixing of the staining agent.

  Each discharge port 51 is provided with a flow meter 54. The flow meter 54 measures the amount of the stain discharged from each discharge port 51. The flow meter 54 is connected to a control device (not shown), and the discharge amount of the stain from each discharge port 51 measured by the flow meter 54 is sent to the control device and managed.

Each discharge port 51 is provided with an adjustment unit 53. The adjustment unit 53 performs discharge of the stain from the discharge port 51, change of the discharge amount of the stain, and stop of discharge of the stain. As the adjustment unit 53, for example, a valve body can be typically used. The adjusting unit 53 such as a valve body may be manually operated, but is preferably connected to the control device and can mechanically restrict discharge (increase / decrease discharge amount) and stop discharge. An example of such an adjusting unit 53 is an automatic valve. Moreover, since it is comparatively simple, the adjustment part 53 may have a function only to switch the discharge of the stain and the stop of the discharge. As such an adjustment part 53, a solenoid valve is mentioned, for example. The discharge and stop of the staining agent by the adjusting unit 53 such as the automatic valve or the electromagnetic valve is managed by the control device and can be automatically controlled, for example. The adjustment unit 53 may be provided on the upstream side of the flow meter 54 as shown in FIGS. 5 to 7, or may be provided between the discharge port 51 and the flow meter 54.
In addition, when managing discharge and stop of the staining agent by the control device, it is necessary to adjust the adjustment unit 53 based on the data measured by the flow meter 54, so the adjustment unit 53 is located upstream of the flow meter 54. Will be provided.

Each discharge port 51 is connected to the tank 56 via supply tubes 551 and 552. In addition, in FIG.6, FIG.7, FIG.9, although supply tube 551,552 is each represented by different length, it is preferable that all are the same length. By using the supply tubes of the same length, the pressure in each supply tube becomes substantially uniform, the stain can be supplied to the discharge port 51 at a uniform speed, and the flow rate of the stain can be accurately controlled. .
The number of tanks 56 may be one, but a plurality of tanks 56 are provided in order to discharge two or more kinds of stains from independent discharge ports 51. In the illustrated example, two tanks 56 are illustrated for convenience. That is, in the illustrated example, there are two sets of dyeing agent supply units including one tank and a member connected to the tank. Hereinafter, when distinguishing between tanks and discharge ports included in these stain supply parts, terms may be prefixed with “first” and “second”, respectively.
In the present invention, it is sufficient that two or more sets of staining agent supply units including at least a tank, a supply tube, an adjustment unit, and a discharge port are provided, and three or four sets of these may be provided. Since the number of types of dyeing agents can be increased according to the number of sets of dyeing agent supply units, the number of colors in the color pattern displayed on the live machine can be increased, but on the other hand, the dyeing machine becomes more complicated and large. To go. In consideration of these, the number of sets of the dye supply unit is set.

The first tank 561 is provided with a first pump 571. A first manifold 591 is provided on the downstream side of the first tank 561 through a first supply pipe 581. A plurality of first supply tubes 551 are connected to the first manifold 591, and a first discharge port 511 among the plurality of discharge ports 51 is connected to each first supply tube 551.
The first manifold 591 branches the stain supplied from the first tank 561 to the first supply tubes 551. The staining agent is sent from the first tank 561 to the first manifold 591 through the first pump 571, and the staining agent is discharged from the first discharge port 511 after passing through each adjustment unit 53 and the flow meter 54. .

The second tank 562 is provided with a second pump 572. A second manifold 592 is provided on the downstream side of the second tank 562 through the second supply pipe 582. A plurality of second supply tubes 552 are connected to the second manifold 592, and a second discharge port 512 among the plurality of discharge ports 51 is connected to each second supply tube 552.
The second manifold 592 branches the stain supplied from the second tank 562 to each second supply tube 552. The staining agent is sent from the second tank 562 to the second manifold 592 through the second pump 572, and the staining agent is discharged from the second discharge port 512 after passing through each adjustment unit 53 and the flow meter 54. .

  The first discharge port 511 connected to the first tank 561 and the second discharge port 512 connected to the second tank 562 can be appropriately selected from the discharge ports 51 arranged in the width direction. Since the tone design can be easily dyed, for example, the first discharge ports 511 and the second discharge ports 512 are alternately arranged one by one in the width direction. In addition, it is not restricted to such arrangement | positioning, For example, the 1st discharge port 511 and the 2nd discharge port 512 may be alternately arrange | positioned 2-5 pieces at a time in the width direction. Further, the alternate arrangement is not limited to the same number, and may be arranged with different numbers of discharge ports, such as alternately arranging one first discharge port and two second discharge ports. Good.

  In addition, when there are three or more tanks 56, several discharge ports are connected to each tank, but in order to form a striped blurred tone due to each stain, some of each tank 56 are connected to each tank. The arrangement of the discharge ports is also preferably alternate. For example, when three tanks are provided, some first outlets connected to the first tank, some second outlets connected to the second tank, and some third outlets connected to the third tank Can be arranged in various patterns such as alternately arranged one by one in the width direction, alternately arranged two to five in the width direction, or alternately instead of the same number. .

The manifold may be omitted as appropriate.
Further, each tank 56 is provided with a pump 57 for mainly sending the stain to the manifold. However, as will be described later, the stain is not necessarily discharged from each discharge port 51 under pressure. Therefore, the pump 57 may be omitted. When the pump 57 is omitted, for example, by installing each tank 56 at a position higher than each discharge port 51, the staining agent can be supplied from each tank 56 to the discharge port 51 with potential energy.

[Continuous dyeing method for carpet]
Next, the continuous dyeing method for carpets of the present invention will be described.
The method for continuous dyeing of carpets of the present invention can be performed as a single step incorporated in the manufacture of carpets.
For example, the carpet manufacturing method includes a preparation process for an undyed raw machine, a pretreatment process for the green machine, a dyeing process for the green machine, and a back layer forming process, and may include other processes as necessary. Good.
Each of these steps may be performed in series on one production line, or one or more steps selected from the above steps may be performed on one line and the remaining steps may be performed on another one or Two or more lines may be used. Further, all of the steps may be performed by one practitioner, or one or more steps selected from the steps may be performed by one practitioner, and the remaining steps may be performed by another practitioner. The person may go.

<Preparation of live equipment>
A long strip-shaped unstained living machine B is produced. The undyed living machine B can be obtained by tufting pile yarns on a long belt-like base fabric.
The pile yarn is not particularly limited as long as it can be dyed with a dyeing agent in a later-described dyeing step, and may be a pile yarn itself or a pile yarn colored in a desired color.
As the pile yarn, conventionally known yarns can be used, and examples thereof include synthetic fibers made of thermoplastic resin, natural fibers such as cotton and wool, and mixed fibers of synthetic fibers and natural fibers. The material of the synthetic fiber is not particularly limited, and examples thereof include polyamide, acrylic, polyester, polypropylene, polyvinyl alcohol, polyurethane, cellulose, and polyvinyl chloride. Since various colors can be satisfactorily dyed, it is preferable to use a pile yarn including a polyamide resin fiber or a pile yarn consisting only of a polyamide resin fiber.
The pile yarn tufted on the base fabric may be a cut pile or a loop pile. The pile height is not particularly limited, and is, for example, 1 mm to 20 mm, preferably 2 mm to 10 mm. Furthermore, the pile height may be constant or different. By tufting the pile yarn with different pile heights, it is possible to form an uneven pattern due to the pile height on the surface of the living machine.
In addition, after forming piles by tufting pile yarn on the base fabric, if necessary, a sealing layer made of an adhesive or the like is formed on the back surface of the base fabric to prevent the pile yarn from coming off. Also good.

<Pretreatment process>
Using the conveying device 3 of the continuous dyeing machine A, the unstained green machine B having a long belt shape is conveyed in the longitudinal direction.
As shown in FIG.10 and FIG.11, the processing agent C is apply | coated to the surface of the raw machine B from the pre-processing part 4 arrange | positioned in the middle of conveyance.
As the treating agent C, a liquid material having fluidity is used. The treating agent C includes at least one of a dye-resisting agent and water, and may include other components as necessary. Examples of other components include a viscosity adjusting agent such as a paste, a pH adjusting agent, a dye, and a leveling agent.

The anti-dyeing agent does not contain a dyeing component and does not have a dyeing function itself, and substantially prevents dyeing of the dyeing agent on undyed pile yarn, or is not dyed with a dyeing agent. The pile yarn is allowed to be slightly dyed (in other words, incomplete dyeing of the pile yarn by the dyeing agent). As the dye-proofing agent, conventionally known ones can be used, and examples thereof include aromatic sulfonic acid condensation polymer compounds, aromatic sulfonates, polyhydric phenol condensation polymer compounds, and glycols. .
The water allows the undyed pile yarn to be dyed by the dyeing agent, but reduces the coloration.
In order to fix the processing agent C applied to the surface of the living machine B and to adjust the viscosity of the processing agent C, the paste is blended with the processing agent C as necessary. A conventionally well-known thing can be used as a paste, For example, water-system adhesives, such as a polyvinyl alcohol-type adhesive agent, are mentioned.
In order to impart a slight color to the processing agent C, the dye is blended in the processing agent C as necessary.

In the first example, the processing agent C includes water and a paste.
In the second example, the treatment agent C is composed of water, a paste, a dye, and a pH adjuster.
In the third example, the processing agent C is composed of water, a paste, and a dye.
In the fourth example, the treatment agent C is composed of an anti-dyeing agent, water, a paste, and a pH adjuster.
In the fifth example, the treating agent C is composed of an anti-dyeing agent, water, a paste, a dye, and a pH adjuster.
In the sixth example, the treatment agent C is composed of a dye-proofing agent, water, a paste, and a dye.
In the seventh example, the treatment agent C is composed of a dye-proofing agent, water, and a paste.
In the eighth example, the treating agent C is composed of an anti-dyeing agent, a paste, a dye, and a pH adjuster.
In the ninth example, the treatment agent C includes water, a dye, and a pH adjuster.
In the tenth example, the treating agent C is composed of water and a dye.
In the eleventh example, the treating agent C is composed of an anti-dyeing agent, water and a pH adjusting agent.
In the twelfth example, the treating agent C is composed of an anti-dyeing agent, water, a dye, and a pH adjuster.
In the thirteenth example, the treatment agent C is composed of a dye-resisting agent and a pH adjusting agent.
In the fourteenth example, the treatment agent C is composed of only a stain-proofing agent.
In the fifteenth example, the processing agent C consists only of water.
In the present embodiment in which the treatment agent is applied by the roll 41, the treatment agent C preferably contains water and a paste, and for example, is preferably selected from the first to seventh examples.

Although the viscosity of the processing agent in this embodiment is not specifically limited, Preferably, it is 50 mPa * s-10000 mPa * s, More preferably, it is 100 mPa * s-8000 mPa * s. By using the processing agent C having such a viscosity, the processing agent C can be satisfactorily applied to the living machine B using the roll 41, and the applied processing agent C does not spread unnecessarily.
However, in this specification, the viscosity of the treating agent is measured at 23 ° C. using an E-type viscometer (model “VISCONIC E” manufactured by Tokyo Keiki Co., Ltd., rotation speed: 25 to 100 RPM).

When a plurality of rolls 41 (in the illustrated example, the first roll 411 and the second roll 412) are used as described above, the same treatment agent C may be applied to each roll 41, or different treatments may be performed. Agent C may be applied.
For example, in the first roll 411, one type of treatment agent C (for example, the treatment agent C of the first example) is applied, and in the second roll 412, the same treatment agent C (for example, the first example of the treatment agent C of the first example). Treatment agent C) is applied. Alternatively, one type of treatment agent C (for example, the treatment agent C of the first example) is applied to the first roll 411, and a different treatment agent C (for example, the fourth example of the fourth example) is applied to the second roll 412. Treatment agent C) is applied.

As described above, the processing agent C is applied to the living machine B at the application portion of the roll 41. Hereinafter, the portion of the surface of the living machine B where the processing agent C is applied is referred to as a “processing agent adhesion portion”.
For example, when the roll 41 provided with the spot-like application portion is used, the treatment agent C is applied to the surface of the living machine B in the same planar view shape as the spot-like shape, and the plane The treatment agent adhering portions having a visual shape are formed at predetermined intervals in the longitudinal direction of the living machine B. That is, a plurality of spotted treatment agent adhering portions in the longitudinal direction are formed on the surface of the living machine B. In this case, the treating agent adhering portions are discontinuous in the longitudinal direction.
On the other hand, for example, in the case of using the roll 41 provided with a continuous-shaped coating portion, a treatment agent adhering portion having a planar view band shape extending continuously in the longitudinal direction is formed on the surface of the living machine B. To go.

When a plurality of rolls 41 (in the illustrated example, the first roll 411 and the second roll 412) are used, the processing agent adhering portions formed by application of the processing agent C of the respective rolls 41 are partially overlapped. Or they may not overlap each other. The part of the processing agent adhesion part overlaps, for example, the part of the processing agent adhesion part formed by application of the second roll 412 overlaps with the treatment agent adhesion part formed by application of the first roll 411. Say. The fact that none of the treatment agent adhering portions overlaps means that, for example, the treatment agent adhering portion formed by applying the second roll 412 does not overlap the treatment agent adhering portion formed by applying the first roll 411. Say.
From the significance of using a plurality of rolls 41, it is preferable that each roll 41 is configured to apply treatment agent C so that the treatment agent adhering portions formed by them do not overlap. When the treatment agent C is applied so that the treatment agent adhering portions overlap, the upstream roll 41 (first roll in the illustrated example) is applied to the application portion of the downstream roll 41 (second roll 412 in the illustrated example). 411) may come into contact, and the downstream roll 41 may be contaminated with the upstream roll 41 processing agent.

In FIG. 10, for easy understanding, the treatment agent adhesion portion by the first roll 411 is given a left-down oblique line and the treatment agent adhesion portion by the second roll is given a right-down oblique line for convenience. ing.
In FIG. 10, the treatment agent adhering portion based on the first roll 411 has a substantially rectangular shape in plan view, and the treatment agent adhering portion based on the second roll 412 has a band shape in plan view. The treatment agent adhering portion based on the first roll 411 and the treatment agent adhering portion based on the second roll 412 do not overlap each other and are spaced apart in the width direction of the living machine B.
In addition, the planar view shape of the processing agent adhesion part by each roll 41 is not limited to this, The processing agent C can be apply | coated to various shapes by setting the form of the application part of the roll 41 suitably. In addition, on the peripheral surface of each roll 41, by disposing the coating portion at an appropriate position in the circumferential direction and / or the axial direction, the treatment agent adhering portions formed by each roll 41 as described above do not overlap. Can be. In this case, even when the application part of each roll 41 has the same shape and the same size (for example, a substantially rectangular shape having the same size, for example), by disposing the application part in each roll 41, It is possible to prevent the treatment agent adhering portions formed by 41 from overlapping.
The dyeing process is performed after the pretreatment.

<Dyeing process>
Using the conveying device 3 of the continuous dyeing machine A, the undyed raw machine B subjected to the pretreatment is conveyed in the longitudinal direction. As shown in FIGS. 10 and 11, the staining agent is discharged from each discharge port 51 arranged in the middle of conveyance, and the staining agent is applied to the surface of the living machine B from its lower end along the surface of the guide plate 52. .
As described above, in the continuous dyeing machine A provided with a plurality of tanks 56, different dyeing agents are usually placed in the respective tanks 56. However, even in the continuous dyeing machine A provided with a plurality of tanks 56, the same dyeing agent may be put in at least two tanks selected from the plurality of tanks 56, or all tanks may have the same dyeing. An agent may be added.
The different dyes are: (a) dyes with different colors for dyeing pile yarn, (b) dyes with the same color but different color depth, (c) dyes with the same color but the dyes themselves (D) different types of dyes as described later (for example, acid dyes and cationic dyes are different kinds of dyes), (e) selected from (a) to (d) above A combination of at least two, and the like.

For example, a dyeing agent capable of dyeing pile yarn in a desired color (for example, blue) is placed in the first tank 561, and a pile yarn is dyed in a different color (for example, white) in the second tank 562. The possible dyeing agent is put. Further, for example, an acidic dye having a desired color is placed in the first tank 561, and a cationic dye having a desired color is placed in the second tank 562. Hereinafter, these different stains may be referred to as a first stain and a second stain.
In the above, a dyeing machine having two sets of the dye supply unit including the tank, the supply tube, the adjusting unit, and the discharge port is illustrated. However, when three or more sets of the dye supply unit are provided, It is preferable that different stains are discharged from the respective supply units.
Further, the dyeing agent put in each tank may be a combination of various dyes, for example, a mixed dye in which an acid dye and a cationic dye are mixed, a dye in which a plurality of acid dyes are mixed and adjusted to a desired color, etc. Good.

The type of the dyeing agent can be appropriately set according to the pile yarn, and examples thereof include dyes and pigments, and dyes are preferably used. Examples of the kind of the dye include acid dyes, cationic dyes, metal-containing dyes, disperse dyes, direct dyes, reactive dyes, fluorescent dyes, sulfur dyes, and combinations thereof.
As the dyeing agent, a liquid material having fluidity is used.
The viscosity of the stain is not particularly limited, but if the viscosity is too large, the stain does not flow well on the surface of the guide plate 52, and if the viscosity is too small, the stain flows along the surface of the guide plate 52 at an early stage. There is a risk that. From this viewpoint, the viscosity of the staining agent is preferably 0.6 mPa · s to 100 mPa · s, and more preferably 0.6 mPa · s to 10 mPa · s.
However, in this specification, the viscosity of the staining agent is measured at 23 ° C. using an E-type viscometer (model “VISCONIC E” manufactured by Tokyo Keiki Co., Ltd., rotation speed: 0.5 to 100 RPM).

The discharge speed of the staining agent from each discharge port 51 is not particularly limited, and is independently, for example, 0.2 to 10 L / min, and preferably 0.5 to 5 L / min. By setting the discharge speed within the above range, it is possible to effectively prevent the stain from splashing on the guide plate 52.
The staining agent is discharged from each discharge port 51.
The discharge property of the stain from each discharge port 51 is not particularly limited, and the stain may be discharged in the form of a mist, but the first stain and the second stain (different stains on the guide plate 52). 11), it is preferable to discharge each stain from the discharge port 51 substantially linearly as shown in FIG. The dyeing agent discharged from each discharge port 51 first falls in a stripe shape on the guide plate 52.

When the first stain D1 is discharged from the first discharge port 511 and the second stain D2 is discharged from the second discharge port 512 onto the guide plate 52, the first stain D1 and the second stain D2 are guided to the guide plate 52. It flows along the top toward the lower end 521 side of the guide plate 52. Then, the first stain D1 and the second stain D2 expand in the width direction toward the lower end 521 side of the guide plate 52, as if two rivers merge in the region near the lower end 521 of the guide plate 52. While both stains are mixed, the transition is made from the lower end 521 of the guide plate 52 to the surface of the living machine B.
In FIG. 10, for the sake of simplicity, innumerable dots are attached to the first staining agent and hatching is added to the second staining agent (the same applies to FIGS. 12 and 14).
Thus, the 1st dye D1 and the 2nd dye D2 which were previously mixed on the induction | guidance | derivation board 52 transfer to the living machine B, Therefore The 2nd dye D2 (or 2nd dye) from 1st dye D1 The color change is continuous from D2 to the first dye D1). Therefore, both the dyeing agent is mixed and applied between the region where the first dyeing agent D1 is mainly applied, the region where the second dyeing agent D2 is mainly applied, and the two regions. The changed gradation area is formed on the surface of the living machine B.

Further, based on the discharge amount of the stain from each discharge port 51 measured by the flow meter 54, the adjustment unit 53 of each discharge port 51 is operated to increase or decrease the discharge amount of the stain from any discharge port 51. Or it can be stopped.
Regardless of the discharge amount of the staining agent by the flow meter 54, the adjustment unit 53 can be operated to increase or decrease the discharge amount of the staining agent from an arbitrary discharge port 51, or to stop it. Each adjustment unit 53 is independent, and the adjustment unit 53 can increase, decrease, and stop the discharge amount of the stain from each discharge port 51 independently for each discharge port 51. In addition, each discharge port 51 may be divided into a plurality of groups, and the increase / decrease and stop of the discharge amount of the stain from the discharge port 51 may be controlled independently for each group.

  The operation of the adjustment unit 53 is controlled by, for example, a control device (not shown) as described above. In the control device, for example, automatic control such as feedback control is performed such that when the numerical value of the flow meter 54 is large, the discharge amount of the staining agent is decreased, and conversely, when the numerical value is small, the discharge amount is increased. By performing such control, the discharge amount can be stabilized regardless of the physical properties such as the type and viscosity of the stain and the environmental change. The administrator manually operates the adjustment unit 53 to change the staining conditions such as the staining density, the color mixture state, and the switching of the staining agent, or to adjust the discharge amount while looking at the flow meter 54. You may do it. When an ON / OFF type such as a solenoid valve is used as the adjusting unit 53, the dyeing agent is discharged and stopped at each discharge port 51. By controlling the discharge and stop of the staining agent at each discharge port 51, it is possible to change the coloring condition such as the color mixture state and the switching or replacement of the staining agent.

For example, as illustrated in FIG. 12, the staining unit 53 stops the staining agent from one or more first ejection ports 511 among the plurality of first ejection ports 511. Alternatively, the adjustment unit 53 stops the staining agent from one or more second discharge ports 512 among the plurality of second discharge ports 512. Since the stain does not come out from the stopped discharge port 51, the stain from the discharge ports 51 on both sides of the discharge port 51 mixes on the guide plate 52, and the surface of the living machine B from the lower end 521 of the guide plate 52. To move on.
In FIG. 12, the stain from the second second discharge port 512 and the seventh first discharge port 511 from the upper side of the drawing is stopped by the adjustment unit 53. In this case, the first staining agent from the first and third first discharge ports 511 from the upper side is mixed, but the second discharge port 512 second from the upper side is stopped, so the mixed first staining is performed. The concentration of the agent decreases. For this reason, the living machine B is also lightly dyed in this region, resulting in a blurred tone. The same applies to the second stain from the sixth and eighth second discharge ports 512 from the upper side.

Although not particularly illustrated, in another embodiment, the amount of the staining agent from one or more of the first discharge ports 511 among the plurality of first discharge ports 511 is decreased by the adjustment unit 53. Alternatively, the amount of the stain from one or more second discharge ports 512 among the plurality of second discharge ports 512 is decreased by the adjustment unit 53. Since the discharge of the stain from the discharge port 51 squeezed by the adjusting unit 53 is reduced, the guide plate 52 is mixed with the stain from the discharge port 51 while the stain from the discharge ports 51 on both sides is greatly mixed. The lower end 521 of the machine moves to the surface of the living machine B.
Although not particularly illustrated, in another form, the adjustment unit 53 increases the amount of the staining agent from one or more first discharge ports 511 among the plurality of first discharge ports 511. Alternatively, the adjustment unit 53 increases the amount of the staining agent from one or more second discharge ports 512 among the plurality of second discharge ports 512.
Stop, decrease, and increase of these stains can be arbitrarily selected from each discharge port 51.

<Post-processing process>
As shown in FIG. 3, the living machine B1 coated with the dyeing agent preferably fixes the dyeing agent by applying steam to the pile surface through a steam chamber 91 as necessary. By hitting the steam, the raw machine B1 is less likely to be discolored.
Further, it is preferable to clean the pile surface by passing the living machine B1 through the cleaning chamber 92 as necessary. The remaining staining agent and the like can be removed by washing. The cleaning liquid is not particularly limited as long as it can remove residual components such as a staining agent and a processing agent, and examples thereof include water or low-concentration alcohol water. The temperature of the cleaning liquid is usually about 5 ° C to 50 ° C. The cleaning method is not particularly limited, and examples thereof include a method of spraying the cleaning liquid onto the living machine B1, and a method of passing the living machine B1 into a bath filled with the cleaning liquid.
In addition, after cleaning, the living machine B1 is dried. The drying method is not particularly limited, and examples include natural drying and drying using warm air.

<Back layer formation process>
A back surface layer is formed on the back surface of the dyed green machine B1. The back layer can be formed by a conventionally known method.
By forming the back layer, a long belt-like carpet is obtained. The back layer may be formed before the dyeing process. In this case, the dyeing process is performed on the undyed living machine B having the back layer formed on the back surface. Moreover, when a back surface layer is comprised from several layers, the formation process of the back surface layer may be divided into two or more, one may be performed before a dyeing process, and the rest may be performed after a dyeing process.
By cutting the long belt-like carpet thus obtained into a desired shape, a sheet-like carpet 1 as shown in FIG. 1 is obtained. In addition, you may store and convey with a long strip-like carpet.

The continuous dyeing machine and continuous dyeing method of the carpet of the present invention can continuously dye the long strip-shaped raw machine B, and are excellent in carpet production efficiency.
Furthermore, in the continuous dyeing machine and the continuous dyeing method of the present invention, the pretreatment unit 4 is provided on the upstream side of the dyeing unit 5, and the pretreatment unit 4 includes at least one of a stain-proofing agent and water. C is applied to the living machine B. For this reason, after that, when the staining agent is applied at the staining portion 5, the central portion of the treatment agent adhering portion is hardly dyed with the staining agent and becomes a thin color, and gradually goes from the central portion toward the periphery of the treatment agent adhering portion. It becomes darker and becomes the color of the stain on the outside of the treatment agent adhering portion.
The blur color pattern can be adjusted by adjusting the viscosity of the treatment agent C, and when using the treatment agent C containing the anti-fouling agent, by adjusting the content ratio of the anti-dye agent. Can be controlled. For example, when the processing agent C having a high viscosity is used, the gradation becomes weak and the contour is clearly displayed. On the contrary, when the processing agent C having a low viscosity is used, the gradation becomes strong. Further, when the treatment agent C having a high content ratio of the anti-dyeing agent is used, the blurring tone becomes strong, and when the processing agent C having a low content rate of the anti-dyeing agent is used, the blurring tone becomes weak.

As described above, according to the present invention, the living machine B1 can be dyed in a blurry color pattern with a natural feeling that the stain has oozed out around the treatment agent-attached portion, and the treatment agent C is applied to a desired portion. By doing so, the living machine B1 can be dyed in various blurred tone color patterns.
In particular, in dyeing using a continuous dyeing machine, conventionally, it is difficult to expose a pattern that is not continuous in the longitudinal direction. In this regard, according to the present invention, the processing agent C can be spot-coated in the longitudinal direction of the living machine B, and in this case, a discontinuous processing agent adhering portion is formed in the longitudinal direction of the living machine B ( For example, a color pattern that is not continuous in the longitudinal direction can be displayed. Thus, according to the present invention, various color patterns can be displayed on the living machine.

Moreover, since the dyeing | staining part 5 is provided with the induction | guidance | derivation board 52 under the several discharge outlet 51, it can dye | stain the living machine B in a favorable gradation color pattern further.
Specifically, as described above, the first stain D1 and the second stain D2 from the first discharge port 511 and the second discharge port 512 (each discharge port 51) are mixed on the guide plate 52 in advance. Move to live B while meeting. Since the first stain D1 and the second stain D2 flowing on the guide plate 52 are mixed according to the fluidity of the stain itself, a natural and unnatural gradation is generated between the two stains. By shifting to the living machine B, the surface of the living machine B is between the area stained with the first staining agent D1, the area stained with the second staining agent D2, and the two color areas. It is possible to dye a good gradation color pattern having two colorants mixed and a gradation region of natural color change. This gradation area continuously changes from the color of the first stain D1 to the color of the second stain D2 (the color of the second stain D2 to the color of the first stain D1), and the natural color Carpets with varying blur designs can be provided. In the case where the first stain and the second stain are the same color, the gradation area has a single color and the gradation of the color becomes lighter.

The continuous dyeing machine A having the dyeing unit 5 in addition to the pretreatment unit 4 has an area dyed with the first dyeing agent D1, an area dyed with the second dyeing agent D2, and a gradation of natural color change. In areas where the region overlaps with the treatment agent adhering portion, a thin color that is hardly dyed with the staining agent and a natural tone-like color pattern in which the staining agent exudes are generated. For this reason, by combining the dyeing part with the pre-processing part, it is possible to display a more natural and gradation color pattern in a more complex and diverse manner.
In addition, the pretreatment unit 4 and the staining unit 5 can efficiently and massively dye the entire living machine while displaying the color pattern in the continuous staining of the staining unit 5.

Further, since the discharge amount of each stain is measured by the flow meter 54, it is possible to find a situation such as an unintentionally large amount of stain being discharged from each discharge port 51. The amount of the staining agent at the discharge port 51 can be adjusted.
Moreover, since the adjustment part 53 is provided in each discharge port 51, the discharge amount of a dyeing agent can be controlled independently for every discharge port 51, and the living machine B1 can be dye | stained to a various gradation color pattern.

[Other Embodiments]
The present invention is not limited to the above-described embodiment, and various modifications can be made within the intended scope of the present invention. Hereinafter, other embodiments of the present invention will be described. However, in the description, configurations and effects different from those of the above-described embodiments will be mainly described, and the same configurations and the like will be referred to by using terms or symbols as they are. The description of the configuration may be omitted.

In the above-described embodiment, the roll 41 is used as the preprocessing unit 4. However, for example, as shown in FIG. 13, a spray 42 may be used.
The spray 42 sprays the processing agent C in a mist form. Although the number of sprays 42 may be one, it is preferable that a plurality of sprays 42 are provided in the width direction of the living machine B as in the illustrated example. A tube for supplying the treatment agent to the spray 42 is omitted on the way.
Further, as shown in the figure, the plurality of sprays 42 may be arranged in a row in the width direction of the living machine B, or although not particularly shown, the rows arranged in the width direction are two rows in the longitudinal direction. They may be arranged side by side, or may be alternately arranged in a width direction and a longitudinal direction (in a staggered manner in a plan view). Moreover, you may provide the spray 42 so that a movement in the width direction and / or an up-down direction etc. is possible. For example, the spray 42 may be provided with a moving device (not shown). In this case, by applying the treatment agent while moving the spray 42 in the width direction, for example, a wave-like treatment agent adhering portion meandering in the longitudinal direction can be formed on the surface of the living machine B. Can be expressed.

  The material of the spray 42 is not particularly limited, and examples thereof include metals and synthetic resins. Among these, the spray 42 is preferably made of stainless steel because it is excellent in corrosion resistance and hardly adheres to the stain.

The continuous dyeing machine in which the spray 42 is used as the pretreatment unit 4 also uses the conveying device 3 in the same manner as described above to convey the long strip-shaped undyed green machine B in the longitudinal direction thereof, as shown in FIGS. As shown, the treatment agent C is applied to the surface of the living machine B from the spray 42 (pretreatment unit 4). In FIG. 14, for the sake of convenience, the processing agent is hatched for easy understanding of the portion where the processing agent is applied.
The treating agent C is not particularly limited. In the present embodiment in which the treatment agent is applied by the spray 42, the treatment agent C does not necessarily include a paste. For example, in the present embodiment, various treatment agents C such as the first to fifteenth examples exemplified above can be used as the treatment agent C, and it is preferably selected from the ninth to fifteenth examples.
Although the viscosity of the processing agent in this embodiment is not specifically limited, Preferably, it is 0.1 mPa * s-5000 mPa * s, More preferably, it is 0.5 mPa * s-3000 mPa * s. By using the processing agent C having such a viscosity, the processing agent C can be satisfactorily applied to the living machine B using the spray 42.

The treatment agent C sprayed from each spray 42 may be the same or different for each spray 42. In the illustrated example, one treatment agent C is sprayed from several sprays C among the plurality of sprays 42 to the living machine B, and a different treatment agent C is sprayed from the remaining spray 42 to the living machine B. Yes. In FIG. 14, one type of treatment agent is provided with a left-downward oblique line, and a different treatment agent C is provided with a right-downward oblique line.
Even in the pretreatment unit 4 using the spray 42, as in the above-described embodiment, the pretreatment unit 4 applies various treatment agents C including at least one of a dye-proofing agent and water to a desired portion. The living machine B1 can be dyed in a blurred color pattern.
In particular, when the spray 42 is used, the treatment agent C having a relatively low viscosity can be applied, so that a more natural color tone pattern can be expressed.

  Furthermore, in the dyeing process of the above embodiment, different stains are applied to the living machine B from the respective discharge ports 51. For example, the same stain agent may be applied to the living machine B from all the discharge ports 51. In this case, the carpet production machine B has only one color in color, but since the treatment agent C is applied, the shade of the natural color is produced in the treatment agent adhering portion, and the one-color blur tone carpet is formed. can get.

Moreover, although the dyeing | staining part 5 of the continuous dyeing | staining machine of the said embodiment is independently provided with the flowmeter 54 and the adjustment part 53 in each of the some discharge outlet 51, it does not need to provide these in each discharge outlet 51. Good. Alternatively, a flow meter and an adjustment unit may be provided between the tanks 561 and 562 and the manifolds 591 and 592 without providing these at the discharge ports 51.
Furthermore, the discharge ports 513 of the staining unit 5 are not limited to a plurality of independent ones. For example, as illustrated in FIG. 16, a discharge port 513 having a slit-like opening 513a extending in the width direction of the living machine B may be used. Good. Stain is supplied to the discharge port 513 from the tank 563 through the supply pipe 583, and the stain is discharged onto the guide plate 52 from the opening 513a. In addition, the discharge port 513 in the illustrated example has an opening 513a formed to be approximately the same width as the living machine B to the extent that the staining agent can be applied to the entire width direction of the living machine B. However, the slit-shaped opening is not limited to substantially the same as the width of the living machine B, and may be formed, for example, half or 1/3 of the width of the living machine B (not shown). Moreover, although only one discharge port 513 in the illustrated example is provided for the living machine B, the present invention is not limited to this, and two or more may be provided.

Moreover, although the dyeing | staining part 5 has the guide plate 52, you may make it apply | coat a dyeing agent directly on the surface of the living machine B from an ejection opening, without providing the guide plate 52. FIG.
In addition, the continuous dyeing machine and the continuous dyeing method of the present invention are not limited to the above-described embodiments and modifications, and various design changes can be made within the intended scope of the present invention.
