Description

The present invention relates to printing and dyeing machines in the textile industry, and more particularly to transfer dyeing equipment.

Denim, also known as denim bib, is made of fabric dyed with relatively coarse and thick yarn. The fabric is generally dyed in a dark color such as indigo, is light in color (generally light gray or white after scouring) and is suitable for wearing while working.
Here, at present, denim manufacturing methods are roughly divided into two types. A first manufacturing method includes a method of weaving warp yarns after dyeing, and the manufacturing process is as follows.
That is, the procedure is white thread→dyed thread→yarn-dyed fabric (fabric processing)→cutting→sewing→hand-washing finishing→finishing→packaging. Above all, the warp process is dyed by combining dyeing/sizing and one-step dyeing.
The second method is to dye white cloth into denim, and the traditional production procedure for this method is uncolored cloth such as white → dyeing → colored cloth (fabric processing) → cutting. → Sewing → Hand cleaning → Finishing → Packing. Among them, white cloth (cloth not colored such as white) is characterized by being dyed mainly by a high-temperature, high-pressure overflow jet dyeing machine.
Here, the dyeing machine is composed of a body circulation pump heater, a nozzle, a lift device, a supply cylinder and the like. Then, the fabric (cloth) is repeatedly circulated inside the dyeing machine in a slack state like a rope for dyeing, so that the dye solution is in constant contact with the fabric and penetrates inside the fabric. It is being eroded to

However, current denim manufacturing methods generate a large amount of inorganic salts and dyes to be disposed of in the washing wastewater, which increases the COD (Chemical Oxygen Demand) of the sewage. In addition, its CODcr (COD chromium) is as high as 2200-2800 mg/L, the concentration of suspended solids reaches 300-400 mg/L, the pH value is 11-13, and the chromaticity reaches 1500-1800 times. , the manufacturing process has a significant negative impact on the environment.
In addition, as environmental protection policies become stricter, it is conceivable that denim production costs will increase in order to comply with environmental standards. Therefore, in recent years, in order to comply with environmental measures standards, a technology has been proposed that can color the surface of denim while reducing contamination during finishing treatment by reducing the consumption of dyes by reducing the contamination caused by dyeing and finishing denim. there is
In addition, paints and reactive dyes are used to color denim fabrics today. In practical applications, Applicants have discovered that indigo and sulfur dyes, for example, exhibit insolubility in water and therefore lack affinity for fibers.
Therefore, indigo dyes and sulfur dyes cannot be used directly for dyeing. A water-soluble leuco body is a light-colored substance, and since it is slightly soluble in water, it can be used for dyeing.
However, if indigo dyes and sulfur dyes are extensively exposed to oxygen in the air, they cannot color the leuco body. Therefore, when dyeing denim with indigo and sulfur dyes, current techniques include rope dyeing, warp sheet dyeing, suspension dyeing, or fabric immersion.
However, the use of these techniques causes the above-described environmental pollution and increases costs.

Embodiments of the invention are described in detail below. According to one embodiment of the present invention, a transfer dyeing apparatus is provided generally as shown in FIG.
The transfer dyeing apparatus 1 includes the following parts. That is, the transfer dyeing apparatus 1 includes a fabric supply unit 2 such as a fabric wheel, a line enlarging unit 3, a tension unit 4, a correction unit 5, a fabric pulling unit 6, a dyeing section setting device 7, a permeating device 8, a sealing device 9, It includes an inert gas filling device (not shown). These components start from the fabric supply unit 2 on the upstream side, move downstream via the fabric pulling unit 6 and the like, and are transported to the permeating device 8 and the sealing device 9 in this order.
An operator can issue instructions to a central control unit (not shown) through a human-computer interaction unit (not shown) to collectively manage and control each unit and device. automatic control.
The fabric to be dyed that can be used with the transfer dyeing apparatus 1 of the present invention is denim 10 or other fabric that is dyed in an inert gas filled environment. In addition, although the denim 10 is mentioned as an example and demonstrated in this embodiment, the main point which restricts a cloth to the denim 10 is not.
As is clear from FIG. 1, the dyeing section setting device 7 of the transfer dyeing apparatus 1 is arranged in the dyeing box 11 . Also, the permeation device 8 of the transfer dyeing apparatus 1 is installed in the permeation box 12 . Also, when viewed from the movement direction of the denim 10, the infiltration box 12 is arranged downstream of the dyeing box 11 and communicates airtightly with the dyeing box 11 through the passageway 13.
A passageway 13 is arranged above the dyeing box 11 and the infiltrating box 12 . As another embodiment, the stain box 11 and the permeation box 12 may be integrally formed. That is, the dyeing box 11 and the permeation box 12 can be configured as the same box, and the dyeing section setting device 7 and the permeation device 8 may be arranged in the same box.
An inert gas filling device (not shown) can fill the dyeing box 11 and the infiltration box 12 with an inert gas such as nitrogen through the inert gas filling inlet 14 .
Inert gas can be simultaneously charged into the staining box 11 and the infiltration box 12 from an inert gas filling inlet 14 via a charging line 15 connected in parallel. Therefore, since they are filled in parallel at the same time, the inert gas can be quickly filled.
By utilizing the communication between the dyeing box 11 and the permeation box 12, only one of the dyeing box 11 and the permeation box 12 can be filled with an inert gas. However, as for the filling speed, more time is required than when the dyeing box 11 and the permeation box 12 are filled at the same time.
In order to prevent inert gas from escaping from the dyeing box 11 and the infiltration box 12 in the operating state to the outside environment, the dyeing box 11 and the infiltration box 12 are hermetically sealed at least when in the operating state. It is desirable to design
The dyeing box 11 can thus be provided with a sealing device 9 at its denim inlet 16 and the permeate box 12 with a sealing device 9 at its denim outlet 17 . Therefore, at least while the transfer dyeing apparatus 1 is in operation, the denim 10 in the dyeing box 11 and the permeation box 12 does not come into contact with oxygen and always stays in an inert gas atmosphere.
As can be seen in FIG. 1, the staining box 11 can have a sliding door 18, which is driven by a motor through a transmission (not shown) such as a rack and pinion transmission.
When the transfer dyeing apparatus 1 is in operation, the sliding door 18 is in the closed position indicated by the solid line. For example, if a part within the staining box 11 needs to be overhauled or replaced, the sliding door 18 can be moved to the open position shown in dashed lines by means of a motor.
Of course, the sliding door 18 can also be moved manually. Furthermore, the infiltration box 12 can also be provided with a part corresponding to a similar sliding door 18 .

Exemplary embodiments of the dyeing section setting device 7, the sealing device 9 and the permeating device 8 of the transfer dyeing device 1 of the present invention will now be described in detail. As is clear from FIG. 1, the staining section set device 7 comprises a pair of direct staining groups 19 and three pairs of transfer staining groups 20 arranged so as to be continuously connected from downstream to upstream. A pair of direct dyeing groups 19 can include two direct dyeing groups 19 on opposite sides of a vertical line or fabric, and a pair of transfer dyeing groups 20 can include two transfers on opposite sides of the same vertical line or fabric. Includes staining group 20.
The number of pairs (pairs) of the direct staining group 19 and the transfer staining group 20 in FIG. 1 and the sequence of arrangement are merely examples, and can be appropriately adjusted based on the actual desired staining conditions.
Generally, the direct dyeing group 19 and the transfer dyeing group 20 are arranged in a rocket-like structure, in which case the transfer dyeing device 1 is also called a rocket transfer dyeing device 1 . As another embodiment, other arrangement methods of the direct staining group 19 and the transfer staining group 20 are also conceivable.
As can be seen from FIG. 2, the pair of direct dyeing groups 19 comprises two symmetrically arranged mesh rollers 21 and two closed blade assemblies 22 respectively provided outside the mesh rollers 21, respectively. Prepare. Each direct dyeing group 19 is thus constructed with one mesh roller 21 and one closed blade assembly 22 .
In the working position, the closed blade assemblies 22 can be pressed against corresponding mesh rollers 21 . Thus, the two blade heads 23 of the closed blade assembly 22 form a closed liquid containing chamber together with the surface of the mesh roller 21 between the two blade heads 23 and the end seal member (not shown). do.
On the other hand, in the non-actuated position, the blade head 23 can be separated from the mesh roller 21 .
As shown in FIG. 1, the right direct dyeing group 19 of the pair of direct dyeing groups 19, the right mesh roller 21, and the closed blade assembly 22 provided therewith, may be mounted on a mounting block 24. can. The mounting block 24 can move laterally and linearly along guide rails (not shown) on the staining box 11 .
A servo motor 25 fixed to the dyeing box 11 is mounted such that by driving the mounting block 24, the mesh roller 21 on the right side of the mounting block 24 approaches or moves away from the mesh roller 21 on the left side located on the opposite side. It can be linearly moved using a transmission mechanism (not shown).
Also, the transmission mechanism associated with the servo motor 25 shown in FIG. Attached to the dyeing box 11 is a left direct dyeing group 19, a left mesh roller 21 and a closed blade assembly 22 provided therewith.
Of course, it is also conceivable to install the left direct staining group 19 on the mounting block 24 and install the right direct staining group 19 on the staining box 11 . The pressure provided by a push mechanism (not shown) acting on mounting block 24 to bring mesh roller 21 into contact with denim 10 is independently adjustable.
The pressure is also adjusted and set by the control system and can be gradually increased or decreased according to a program. In FIG. 1, the entire right-side directly stained group 19 is pushed by the push mechanism to approach the left-side directly stained group 19, and the width of the approach can be 2 cm to 5 cm.
Each mesh roller 21 may have its own servo motor (not shown) to drive it individually.
Of course, it is also conceivable for the two mesh rollers 21 to be driven simultaneously by a servomotor and a suitable transmission mechanism. Denim 10 can be moved between two mesh rollers 21 and sized.
Thus, pretreatment liquids, such as dye accelerators, can be applied to denim 10 via a pair of direct dye groups 19 to improve subsequent dye speed and dye efficiency.

As can be seen from FIG. 3, each pair of transfer dye groups 20 has two opposing transfer rollers 26, two plate rollers 27 each positioned outside the transfer rollers 26, and two plate rollers 27 positioned outside the plate rollers 27, respectively. It includes two closed blade assemblies 22 that are sealed together.
Each transfer dye group 20 thus includes a transfer roller 26 , a plate roller 27 and a closed blade assembly 22 . Plate roller 27 can be a gravure printing plate roller, a flexographic printing plate roller, a rotary screen printing plate roller, an offset printing plate roller, or the like.
In the working position the closed blade assembly 22 can be pressed against the plate roller 27 . Thus, the two blade heads 23 of the closed blade assembly 22 and the surface of the plate roller 27 between the two blade heads 23 and the end seal member (not shown) together form a closed liquid containing chamber. do.
On the other hand, in the non-actuated position, the blade head 23 can be separated from the plate roller 27 . Referring to FIG. 3 , the left transfer dyeing group 20 of the pair of transfer dyeing groups 20 , specifically the left plate roller 27 and closed blade assembly 22 , and the transfer roller 26 are mounted on a mounting block 24 . can be done. The mounting block 24 can move horizontally and linearly on guide rails on the staining box 11 .
Also, a servo motor 25 fixed to the dyeing box 11 can drive the mounting block 24 to move linearly via a transmission mechanism, so that the left transfer roller 26 on the mounting block 24 is , can move toward or away from the opposite right transfer roller 26 .
The servomotor 25 and the associated transmission mechanism can together form a propulsion mechanism for the mounting block 24 . A right transfer dyeing group 20 , specifically a right plate roller 27 , a closed blade assembly 22 associated with the plate roller 27 , and a transfer roller 26 can be attached to the dyeing box 11 .
Of course, as shown in FIG. 1 , the transfer staining group 20 may be placed on the right side of the mounting block 24 and the transfer staining group 20 may be placed on the left side of the staining box 11 . In the embodiment shown in FIG. 1, the right transfer stain groups 20 of the three pairs of transfer stain groups 20 are each attached to a mounting block 24 .
Similarly, the pressure provided by the pushing mechanism against the mounting block 24 to bring the transfer roller 26 adjacent the denim 10 is independently adjustable. The pressure applied by this pushing mechanism is adjusted or set by the control system, and can be gradually increased or decreased according to the contents of the program.
Also, the entire transfer-dyed group 20 on the left side of FIG. 3 is pushed by the pushing mechanism to separate and combine with the transfer-dyed group 20 on the right side. The separation and bonding stroke can be from 2 cm to 5 cm. The transfer roller 26 may be a hard material roller with a rubber surface.
Its surface can be covered with seamless rubber. The rubber is preferably natural rubber, styrene-butadiene rubber, polyurethane rubber, or other rubbers that have good affinity with water-based inks. Preferably, the rubber on the surface of the transfer roller 26 has a Shore hardness of 85 degrees to 90 degrees.
Since the transfer roller 26 of each transfer dyeing group 20 is a hard material roller covered with rubber, the outer diameter of the transfer roller 26 is slightly larger than the outer diameter of the plate roller 27 . This provides a certain tolerance space.
In the transfer printing process, when the rubber transfer roller 26 comes into contact with the plate roller 27, the rubber of the rubber transfer roller 26 is deformed by a predetermined pressure. When the front surface of the plate roller 27 leaves the rubber surface of the rubber transfer roller 26, the rubber surface can immediately return to its original shape. It should be noted that preferably the outer diameter of the plate roller 27 has two ends.

A first end of swing arm 31 is pivotally connected to the protruding end of the piston rod of actuator 29 via a pin. A second end of swing arm 31 is pivotally connected to one end of linkage 32 via a pin.
The other end of linkage 32 is pivotally connected to eccentric bushing 30 . An eccentric bushing 30 can thus be assigned to the plate roller 27 , and by rotating the eccentric bushing 30 with an actuator 29 the plate roller 27 can be moved towards or away from the transfer roller 26 .
Of course, to those skilled in the art, any other transmission method besides the swing arm linkage method described herein can be used to effect the rotational movement of the actuator 29 on the eccentric bushing 30 .
Optionally, a handle can be provided at the end of the swing arm pivot 33 so that the rotation of the eccentric bushing 30 can be manually adjusted by the operator during the debug phase.
When the eccentric bushing 30 rotates to move the plate roller 27 to the pressing position, the distance between the plate roller 27 and the transfer roller 26 decreases, pushing them closer together, and this action causes the transfer roller 26 A pressure of the plate roller 27 is generated against the .
When the eccentric bushing 30 rotates to move the plate roller 27 to a rest position, the distance between the plate roller 27 and the transfer roller 26 increases, and in this condition there is not much pressure between them (and yet , can be both in contact and out of contact), the plate roller 27 does not provide pressure to the transfer roller 26 .
And, when in operation, the plate roller 27 can rotate the eccentric bushing 30 by the pressure assembly 28 and move it to different pressing positions on demand.
By rotating the eccentric bushing 30, the plate roller 27 can be moved to different pressing positions and the distance between the plate roller 27 and the transfer roller 26 can be adjusted, thereby adjusting the plate roller 27 relative to the transfer roller 26. can be adjusted.
Further, since rubber has characteristics of flexibility, elasticity, and low hardness, the deformation of the transfer roller 26 can be finely controlled by adjusting the generated pressure. The eccentric bushing 30 can be set so that the initial position is the rest position. When pressure is applied, the actuator 29 operates to extend the piston rod. By driving the swing arm 31, it is rotated around the central axis of the swing arm pivot 33, thereby driving and operating the link mechanism 32 connected to the swing arm 31. By the operation of the link mechanism 32, By rotating the eccentric bushing 30 and using the rotation of the eccentric bushing 30, the plate roller 27 is moved to the pressing position (see FIG. 3).
As the distance between plate roller 27 and transfer roller 26 decreases and they press against each other, plate roller 27 provides pressure to press transfer roller 26 .
Conversely, when no pressure is required, the actuator 29 operates to retract the piston rod (not shown), driving the swing arm 31 to pivot about the central axis of the swing arm pivot 33. . As a result, the link mechanism 32 connected to the swing arm 31 is driven and moved.
Movement of the link mechanism 32 then drives the eccentric bushing 30 to rotate, and the eccentric bushing 30 rotates to move the plate roller 27 to the rest position so that the distance between the plate roller 27 and the transfer roller 26 is Plate roller 27 does not apply pressure to transfer roller 26 at this time, as both are relieved of pressure.

The stroke of the piston rod of actuator 29 can be set between 80 mm and 200 mm, preferably 100 mm. Each transfer dyeing group 20 can include a plate changer 34 (replacer) that can change the plate roller 27 as needed.
Each transfer dye group 20 includes a tilt plate device 35 that allows fine adjustment of the position and angle of the transfer roller 26 to achieve precise alignment between the transfer roller 26 and an adjacent roller.
Each transfer dyeing group 20 includes an axial stretching device 36 assigned to the plate rollers 27 . This axial stretching device 36 includes an axial plate traction motor (not shown) for adjusting the axial position of the plate roller 27 and a corresponding transmission mechanism (not shown).
Each plate roller 27, each transfer roller 26 may each have its own servo motor 25 to drive the plate roller 27 and transfer roller 26 individually.
Of course, only the transfer roller 26 has its own servomotor 25, and the plate roller 27 and the transfer roller 26 may be synchronously driven by a synchronizing device such as a synchronizing gear.
Denim 10 from a pair of direct dyeing groups 20 moves between the two transfer rollers 26 of each pair of transfer dyeing groups 20 and can be applied with a dye such as indigo dye or sulfur dye. By arranging a plurality (here three) of transfer dye groups 20 in succession, the surface of denim 10 can be evenly coated with sufficient dye.
Dye coating on the denim 10 can be performed under an inert gas atmosphere in the dyeing box 11, and the denim 10 can be colored more reliably by reducing the indigo dye and the sulfur dye to leuco bodies. can.
The dyeing box 11 may be provided with a sealing device 9 at its lower denim inlet 16 and the infiltration box 12 may be provided with a sealing device 9 at its denim outlet 17 formed on its bottom side. The two sealing devices 9 can be the same or different.
A sealing device 9 hermetically seals the dye box 11 and the infiltration box 12 to prevent inert gas from escaping from them. Each sealing device 9 of FIG. 1 is shown simply in FIG. 4 as a pair of airbags 37 having a cylindrical cross-section.

A preferred embodiment of the sealing device 9 will be described with reference to FIGS. 4 and 5. FIG. The sealing device 9 has a case 38 and a plurality of pairs of airbags 37 continuously arranged therein.
The case 38 can be fixedly positioned at the denim inlet 16 of the dyeing box 11 and the denim outlet 17 of the infiltration box 12 . Further, the case 38 can have a fabric inlet and a fabric outlet on opposite side walls thereof, which generally correspond to the cross-sectional structure of the denim 10 .
Each pair of airbags 37 includes a pair of upper and lower airbags 37 . Each airbag 37 is provided with a fixing device 39 at each end thereof. Each airbag 37 can be fixed (preferably non-rotatably) to the sidewalls of the case 38 via fixing devices 39 at both ends.
The sealing device 9 comprises an inflator (filling device) provided to the airbag 37 . The inflator (filling device) includes an air pump 40 and a piping system 41 connected between the air pump 40 and each airbag 37 shown in FIG. The piping system 41 allows the air pump 40 to fill each airbag 37 with gas, such as air, by passing it through the piping system 41 .
In the embodiment shown in FIGS. 4 and 5, the inflator has a piping system 41 connected in parallel to the air pump 40 and each airbag 37 as shown in FIG. The advantage of this design is that there are few parts and all airbags 37 can be inflated at the same time.
However, it is also conceivable to equip each airbag 37 with a separate air pump 40 and piping system 41 . These designs facilitate individual inflation of each airbag 37 . Other arrangements of the air pump 40 and the piping system 41 are also conceivable as long as the air bag 37 can be inflated.
Corresponding switches or valves are also provided in the plumbing system 41 to allow one or more airbags 37 to be inflated or blocked from inflating. Each airbag 37 may have its own air pressure indicator (not shown) by which it can be determined whether the air pressure within the airbag 37 has reached a predetermined threshold.
Then, when the air pressure indicator detects that the air pressure within the airbag 37 is below a predetermined threshold, the airbag 37 can be inflated by the air pump 40 . Then, when the threshold value is exceeded, the filling of the airbag 37 with air is stopped.
Alternatively, these processes can be performed manually. Of course, it can also be automated using a corresponding control device (not shown). After being filled with gas, the airbag 37 has a uniform circular cross-section over substantially its entire length (see FIG. 4). Note that the shape of the cross section may be other shapes.
However, in terms of shape, it is effective to make the cross section of the airbag 37 circular, and each pair of opposing airbags 37 can basically make line contact with the denim 10 after being inflated. , a line contact can apply more pressure than a point contact, for example. Therefore, reliability is enhanced from the viewpoint of hermetic sealing.
Furthermore, the contact line length of the opposing airbags 37 is preferably longer than the width of the denim 10 (see FIG. 5). Therefore, the denim 10 can be hermetically sealed by each pair of airbags 37, greatly enhancing the effect of sealing.
Of course, it is also conceivable that the airbag 37 contacts the surface of the denim 10 after being inflated. The surfaces of the airbags 37 are smooth and even, so that the denim 10 can pass or slide between the opposing airbags 37 . On the other hand, the inert gas in the dyeing box 11 and the infiltration box 12 cannot pass between the airbags 37, effectively blocking the inert gas from leaking.

In the embodiment shown in FIGS. 4 and 5, three pairs of inflated airbags 37 are exemplarily shown along the direction of movement of denim 10 . Denim 10 passes between each pair of airbags 37 in turn.
The airbags 37 are laterally pressed against each other. The left and right airbags are pressed against the sidewalls of case 38, respectively. Both ends of each airbag 37 are pressed against side walls of the case 38 .
As a result, a space as sealed as possible is formed between the three airbags 37 provided on the upper side of FIG. 4, the three airbags 37 provided on the lower side, and the side wall of the case 38. .
However, the ends of the airbag 37 may not be completely adjacent to the side walls of the case 38 (see FIG. 5), so the contact area is less than the cross-sectional area of the airbag 37 . In general, the inert gas still leaks out of the sealed space inside the case 38 through the gaps at both ends of the airbag 37 .
In order to solve this problem, the case 38 of the sealing device 9 preferably has a return port 42 for inactivating the gas above or below the case 38 . Return port 42 penetrates the wall of case 38 .
Therefore, via the return port 42, the inert gas can be returned to the inert gas filling device again by a pipeline (not shown). In this way, the inert gas can be prevented from leaking into the environment through the fabric outlet, and the reuse of the inert gas can be realized.

Returning to FIG. 1, description will be made. In the permeation device 8 according to this embodiment, the guide rollers 43 are provided in two rows, one row on the upper side and one row on the lower side. Axial ends of the guide rollers 43 are preferably rotatably arranged, for example, on side walls of the infiltration box 12 .
Each row of guide rollers 43 includes a plurality of guide rollers 43 (nine in this case) sequentially provided from the upstream side to the downstream side, and the axes of these guide rollers 43 are positioned on the same plane. As for the positional relationship between the upper and lower two rows of guide rollers 43 , for example, they are staggered so that the upper and lower sides are alternately shifted while being shifted by the same width as the width of one guide roller 43 .
As a result, the denim 10 entering the infiltration box 12 is stretched through the guide rollers 43 in a plurality of denim sections 44 alternately winding vertically. In this embodiment, these denim sections 44 travel substantially longitudinally through the infiltration device 8 within the infiltration box 12 .
This longitudinally progressing layout is applicable to textiles. For example, these denim sections 44 extend parallel to each other and the direction of travel to adjacent denim sections 44 is opposite and, after traveling upwards, is redirected by the guide rollers 43 to downwards. proceed.
Adjacent denim sections 44 can be moved up and down at a predetermined angle, but the predetermined angle should be as small as possible in order to maximize the number of denim sections 44 .
As a result, the residence time of the denim 10 in the permeation box 12 can be maximized, and as a result, the dye can increase the permeation power from the surface to the interior of the denim 10 and can be sufficiently permeated. .
The dyes are, for example, indigo dyes and sulfur dyes coated onto the denim 10 via the dyeing station set device 7 . Thus, there is adequate time for reduction to the leuco bodies in an atmosphere of inert gas to better color the denim 10 . The cloth capacity of the infiltration box 12 ranges from 20 meters to 80 meters.

Referring to FIG. 6, in the permeation device 8 according to another embodiment, the guide rollers 43 are arranged in a total of two rows, one row on the left side and one row on the right side. 6 are the same as those in FIG. 1, so description thereof will be omitted.
In the embodiment shown in FIG. 6, the denim section 44 travels substantially laterally (side-to-side) through the infiltration device 8 within the infiltration box 12 . It should be noted that such a horizontal progression layout can be applied to knitted fabrics.
The permeation box 12 can be equipped with an inert gas concentration detector (not shown) inside. The inert gas concentration detection device can detect and further control the concentration of inert gas in the infiltration box 12 so that the concentration of inert gas in the infiltration box 12 is always the most suitable for coloring the denim 10. valid range.
