Description

  The present invention relates to a wood dyeing method, and more particularly to a wood dyeing method for dyeing the inside of wood.

  In recent years, attempts have been made to dye the interior of wood. This is different from the conventional coloring that is done by painting the surface of wood after processing, and by artificially coloring the natural wood grain by sucking up the dyeing liquid into the conduit or mentor of the wood before processing. It is intended to be used as crafts, furniture, decorations, etc. For example, a method of forming a hole or groove in a standing tree and injecting a dye solution therefrom to dye the tree (for example, Patent Documents 1 to 3), or covering a cut end of a tree after cutting and dyeing the bag A method (for example, Patent Document 4) of injecting and dyeing a liquid has been attempted.

Japanese Patent Laid-Open No. 57-11010 JP 2000-254904 A JP 2001-54903 A JP 58-42001 A

  However, when dyeing with standing trees, holes and grooves are formed in the trunk, so that the processed part cannot be used as wood, and there is a problem that the material cannot be used effectively, so-called “yield is poor”. In addition, standing trees vegetated in places where the scaffolding is bad for carrying out complicated processing such as forming steep slopes and cliff edges to form holes and grooves also has a problem that it is difficult to dye. In addition, Tachiki has roots in the soil and absorbs water actively from the roots, so in addition to poor dyeing efficiency, the dyeing solution is diluted and the finished color is much thinner than originally expected. There was a problem that there was something. There is also a problem that the dye solution is lost in the soil through the roots.

  In addition, wood is actively metabolized in the part close to the epidermis (sapwood) and is easy to be dyed because the wood is soft, whereas in the part close to the center of the annual ring (core material), the cells are almost dead. Since it hardly absorbs moisture and nutrients, it is difficult to be dyed. However, when dyeing standing trees, since the boundary position between the sapwood and the core material is unknown from the appearance, the formed holes and grooves reach the core material and are hardly dyed. Furthermore, in the case of wood having a cavity inside, the formed hole or groove may communicate with the cavity, and the dyeing solution may flow through the cavity. In addition, since it is not known from the outside as to which part of the grain the dyeing liquid is injected, the coloring applied by the dyeing can be understood only after cutting. That is, there are many accidental factors, and it was difficult to apply the intended coloring by dyeing.

  In addition, the method of covering the cut wood with a bag and dyeing it was advantageous in terms of effective use (yield) of materials compared to dyeing standing trees. There is a problem that the dyeing solution is supplied to the entire face of the mouth and the dyeing solution is also supplied to the cavity when there is a cavity inside. In addition, there is a problem that the interior of the wood is dyed with a single color as a whole and lacks in design fun.

  Therefore, in view of the above circumstances, the present invention is a wood dyeing method capable of efficiently using wood and efficiently dyeing it, and applying coloring intended to some extent by dyeing, and capable of various dyeings rich in change. It is a problem to provide.

In order to solve the above-mentioned problem, the wood dyeing method according to the present invention is described as follows: “ By driving a dyeing liquid supply tool connected to a dyeing liquid container containing a dyeing liquid into a cut end of a felled wood or the above-mentioned By inserting it into the hole formed in the face of the mouth, it is attached with leaving the air contact surface on the face of the mouth, and the wood is dyed by sucking up the dyeing solution.

  The end of the tree is the surface where the annual rings can be seen at the cut end of the felled wood. The dyeing solution is a solution in which a dye is dissolved in a solvent such as water, and examples of the dye include dye-based inks for inkjet printers, natural dyes such as indigo and safflower, food dyes, and synthetic dyes. Can do.

  Sucking the dyeing liquid from the end of the wood means that the dyeing liquid is sucked up instead of water using the water absorption action of wood. Here, transpiration, osmotic pressure, and capillary action are involved in the water-absorbing action of plants, and it is said that the influence of the transpiration is large. Therefore, it is preferable that the wood to which the present invention is applied is in a state where time has not passed since it was cut, leaves and leaves are attached, biological activity is active, and transpiration is actively performed. is there.

  The dyeing liquid supply tool is not particularly limited as long as it has a part connected to the dyeing liquid container and a part for supplying the dyeing liquid to the wood end of the wood, and supplies the dyeing liquid to the end of the wood. Examples include those in which the opening is formed so as to be in close contact with the face of the mouth, and those having a nozzle part that can be inserted into a hole formed in the face of the mouth. In addition, the stain solution supply tool and the stain solution container may be connected to the stain solution container via a piping member such as a tube, or the stain solution supply tool may be connected to the stain solution container. It can also be mounted directly.

  Therefore, according to the wood dyeing | staining method of this invention, since the felled wood is dye | stained, a dyeing liquid supply tool can be arrange | positioned, visually recognizing the mouth end surface. That is, in the conventional method for dyeing standing trees, the dyeing solution is injected through the formed grooves and holes, and the setting of the dyeing position is in a state of groping. The staining position can be set at a desired position while actually viewing the annual rings. Thereby, after confirming the boundary between the sapwood and the core material, it is possible to dispose the staining liquid supply tool only in the sapwood portion that can be dyed. Further, even in the case of wood having a cavity inside, it is possible to dispose the staining liquid supply tool while avoiding the position of the cavity after confirming the position of the cavity, so that the staining liquid as in the conventional method can be provided. Can be dyed using the dyeing solution effectively without being washed away through the cavity.

  In addition, since the dyeing position can be set to a desired setting, a pattern can be expressed even with a single color dyeing. Furthermore, a desired color scheme can be set using a plurality of staining solutions. In this way, it is possible to perform coloring that is intended to some extent by dyeing, and it is possible to perform a variety of dyeings rich in change. For example, it is possible to express a complex color by mixing a plurality of colors by infiltrating the dyeing liquid into the wood by arranging the dyeing liquid supply tools for supplying the dyeing liquids of different colors in close proximity to each other. it can. On the contrary, by arranging a plurality of color solution supply tools apart from each other, it is possible to express a vivid color scheme that does not mix colors. Alternatively, a portion where the grain is dense can be dyed in a light color so that the grain is raised, and a portion where the grain is rough can be dyed in a dark color. In addition, it is possible to express a rainbow-like color by arranging a dye solution supply tool so that the color changes stepwise.

  Furthermore, since the felled wood is dyed from the direction of the end of the tree and the trunk portion is not processed, the entire portion above the felling site can be used. That is, by cutting near the root, the yield is better than the conventional method in which holes and grooves are formed from the side of the tree and dyed. In addition, by applying the wood dyeing method of the present invention to thinned wood that is harvested and removed in order to reduce the number of trees in forests that have become dense during the growth process, new uses such as crafts and decorative materials can be obtained. It can be found and is significant in terms of effective use of resources.

  In addition, the dyeing process does not need to be performed at the place where the timber is cut down, and it is possible to perform an operation such as attaching the dyeing liquid supply tool after appropriately moving the timber from the cutting place. As a result, it is possible to effectively utilize the wood planted in a place with a poor scaffold and perform dyeing. Moreover, since the roots are not stretched in the soil as in the case of dyeing standing trees, there is no water absorption action from the roots, and the dyeing solution can be sucked up exclusively. In addition, the staining solution is not diluted with water sucked from the roots, and the staining solution does not migrate through the roots into the soil. That is, it is possible to efficiently dye wood, and it is possible to dye it with a color density close to that originally intended.

  Moreover, the wood dyeing | staining method concerning this invention shall be "Coating the air contact surface of the said mouth end surface with a coating agent."

  The coating agent covers the remaining surface of the mouth end where the dyeing liquid supply tool is not attached, that is, the air contact surface that is in contact with the air, and closes the opening of conduits, phloem pipes, etc. In addition to preventing moisture from being absorbed through the surface, the wood is prevented from drying due to evaporation of moisture from the end of the mouth. As such a coating agent, a synthetic resin such as a vinyl acetate resin-based adhesive generally referred to as a bond for woodwork, a synthetic resin that has fluidity when applied to the end of a wood and is cured by irradiation with light or ultraviolet light, etc. And natural resins such as pine ani.

  Therefore, according to the wood dyeing method of the present invention, the end of the mouth other than the portion in contact with the dyeing solution supply tool is blocked by the coating agent, such as a conduit or a pedestrian tube, so that moisture in the atmosphere is absorbed by this portion. The action is prevented. As a result, the force to absorb moisture from the outside due to the influence of the transpiration action and the osmotic pressure acts only on the end face in contact with the dyeing liquid supply tool, and the dyeing liquid is sucked in more effectively. Moreover, it can suppress that a water | moisture content evaporates from an air contact surface, and also drying advances to the inside of a timber. As a result, depletion of the felled wood can be suppressed, the period when the biological activity is actively performed can be prolonged, and the suction of the dyeing liquid that greatly depends on the transpiration activity can be maintained for a predetermined period.

  Furthermore, the wood dyeing method according to the present invention is described as follows: “As the dyeing solution supply tool, an opening for supplying the dyeing solution to the mouthpiece surface is formed in a fan shape, and the dyeing solution supply tool is used as the mouthpiece surface. Can be driven in and mounted. "

  The dyeing liquid supply tool only needs to have a fan-shaped opening, and can be exemplified as a box-shaped one having a cross section parallel to the open surface and having the same shape. Or it can also be set as the polygonal pyramid shape from which the cross section parallel to the open surface reduces gradually. In addition, the dyeing liquid supply tool can be configured to be easily attached to the end of the wood by being hammered or the like by forming the periphery of the opening sharply or by forming it thinner than other parts.

  Therefore, according to the wood dyeing | staining method of this invention, since an opening part is fan-shaped, it has a certain amount of area and can supply a dyeing | staining liquid to the end face. Thereby, the area dye | stained with one dyeing liquid supply tool and the quantity of the dyeing liquid supplied per unit time increase, and wood can be dye | stained efficiently. In addition, since the shape of the opening is a fan shape having arc-shaped sides, it is possible to dispose the staining solution supply tool along the annual ring. Thereby, the dyeing | staining which utilized the pattern of the annual ring peculiar to wood can be performed. In addition, by combining a plurality of dye supply devices and arranging them adjacent to each other, it is also possible to dye the end of the wood into a donut shape. Thereby, it is also possible to dye almost the entire portion corresponding to the sapwood.

  As described above, as an effect of the present invention, the dyeing solution can be effectively used for efficient dyeing, and the usable part of the wood can be increased. A variety of dyeing is possible.

  Hereinafter, the wood dyeing | staining method which is one Embodiment of this invention is demonstrated based on FIG. 1 thru | or FIG. Here, FIG. 1 is explanatory drawing which shows typically the wood dyeing | staining method of this embodiment, FIG.2 (a) is a perspective view of the dyeing liquid supply tool used for the wood dyeing | staining method of this embodiment, ( b) is a bottom view thereof, (c) is an AA end view in (a), and FIGS. 3 (a) and 3 (b) are other dye supply solutions used in the wood dyeing method of the present embodiment. It is explanatory drawing which shows a tool and its attachment state typically.

  In the wood dyeing method of the present embodiment (hereinafter simply referred to as “dyeing method”), first, a tree is cut down to obtain the wood 10 to be dyed. At this time, by cutting the portion close to the root, the portion that can be used after dyeing is large and the yield is good. In addition, it is desirable to keep the branches and leaves attached in order to maintain a state where the transpiration action is active for a predetermined period. In the present embodiment, a case where a cedar having a breast height diameter of about 20 cm is cut and dyed is illustrated. In addition, the dyeing | staining method of this invention can also be applied using the timber 10 already felled as a thinning object tree. In this case, it is desirable that the time has not passed since the felling and the transpiration action is actively performed. If the place where the wood 10 is vegetated is a place with a poor footing such as a steep slope or a cliff, the wood 10 is appropriately moved to a place where the staining work can be performed safely and easily. Can do.

  Next, the dyeing liquid supply tool 20 is attached to the front end 11 of the wood 10. In the present embodiment, the dyeing solution supply tool 20 is one in which the opening 21 is formed in a fan shape. More specifically, the staining solution supply tool 20 is made of steel, and as shown in FIGS. 2 (a) and 2 (b), the cross section parallel to the open surface has an outer arc length of 10.5 cm. The inner arc has a length of 8.0 cm and a width of 3 cm in the same fan shape, and is formed in a box shape having a height of 5 cm. In addition, as shown in the end view of FIG. 2C, the opening 21 is formed with a peripheral edge portion 22 having a thinner thickness than other portions along the edge. The staining liquid supply tool 20 is arranged at a desired position on the end face 11 and the surface opposite to the opened face (upper face 23) is driven with a hammer or the like, so that the peripheral portion 22 is closed over the entire circumference of the opening 21. The staining solution supply tool 20 is attached to the end surface 11 without biting into the surface 11 and without a gap between the peripheral edge portion 22 and the end surface 11. In addition, the material and size of the dyeing liquid supply tool 20 are not limited to those exemplified in the present embodiment, and can be appropriately set depending on the diameter of wood to be dyed mainly. Moreover, the shape of the peripheral part 22 can be sharply formed as a tapered shape or a wedge-shaped cross section with a thickness decreasing toward the tip, and can be driven more easily by the end face 11.

  The attachment position of the staining liquid supply tool 20 to the wood face 11 can be set while the wood 10 is laid down while the eye face 11 is actually visually recognized. Here, in general, the portion close to the dark central portion (core material portion 13) is inactive in biological activity and absorbs moisture and nutrients almost as compared with the outer portion of the annual ring (sapwood portion 12). It is hard to be dyed because it is not done at all. Therefore, it is desirable to avoid the core material portion 13 and to arrange the staining liquid supply tool 20 in the sap material portion 12. Further, in the case of the wood 10 having a cavity (not shown) inside, a cross section of the cavity appears on the end surface of the wood, so that the staining solution supply tool 20 can be disposed avoiding this cavity. In the present embodiment, as shown in FIG. 1, the four staining solution supply tools 20 are arranged at equal intervals along the annual ring with the sapwood portion 12 with the inner arc side of each opening portion 21 facing the center side of the mouthpiece surface. It is arranged with.

  A coating agent (not shown) is entirely applied to the remaining end face 11 to which the staining solution supply tool 20 is not attached, that is, the atmospheric contact surface 15. As a result, the mentor tube and the conduit opening in the end face 11 are closed. In this embodiment, a vinyl acetate resin-based adhesive that is generally marketed as a bond for woodworking is used as a coating agent.

  One end of a vinyl tube 40 is connected to the dyeing solution supply tool 20 attached to the end face 11. Here, on the upper surface 23 of the staining liquid supply tool 20, a cylindrical connection portion 24 protrudes outward, and the tube 40 can be connected thereto. A groove portion 25 is formed on the outer periphery of the connection portion 24, and the tube 40 to be connected is difficult to be removed by contacting the groove portion 25 with the inner wall of the tube 40. The other end of the tube 40 is connected to a staining liquid container 30 that stores the staining liquid 2. At this time, as illustrated in FIG. 1, by connecting the tube 40 via the three-way joint 45, the same color of the staining solution 2 is supplied from one staining solution container 30 to the plurality of staining solution supply tools 20. You can also.

  In this embodiment, the staining liquid container 30 uses a PET bottle having a capacity of 2 liters, and a cylindrical connection portion 34 is attached to the cap 31 and the tube 40 is connected thereto. That is, the staining solution container 30 of the present embodiment is used in an inverted state when supplying the staining solution 2 to the wood 10. Moreover, the connection part 34 attached to the cap 31 is formed with a groove part (not shown) on the outer periphery in order to make it difficult to pull out the connected tube 40 in the same manner as the connection part 24 described above.

  Next, the staining solution 2 is injected into the staining solution container 30. Here, the staining solution container 30 is provided with an injection port 36 for injecting the staining solution 2 at a position that is upward in an inverted state. By forming the injection port 36 on the side surface of the staining liquid container 30, it becomes difficult for rainwater to enter during the staining period. Further, the number of the dye liquid containers 30 corresponding to the number of colors of the dye liquid 2 is used according to a desired color scheme. In this embodiment, a 10% aqueous solution of a dye-based ink for an ink jet printer is used as the staining liquid 2. The injection port 36 may be provided not on the side surface of the staining solution container 30 but on the upper surface in an inverted state, and a cover for preventing the entry of rainwater or the like may be separately attached.

  These staining liquid containers 30 are fixed so that the height of the connection part 34 connected to the tube 40 is higher than the connection part 24 between the staining liquid supply tool 20 and the tube 40 in an inverted state. For example, it is possible to fix the dyeing liquid container 30 to a predetermined height by standing a pole at the site where the dyeing operation is performed and tying the dyeing liquid container 30 with a string or the like or hanging it. Alternatively, the staining solution container 30 can be fixed using a standing tree on site. By fixing at such a height, the staining solution 2 flows down due to gravity, the staining solution 2 is introduced from the staining solution container 30 into the staining solution supply tool 20 through the tube 40, and the mouthpiece surface 11 is opened from the opening 21. To be supplied. In addition, it is possible to make the wood 10 suck up the dyeing solution 2 more efficiently by repeatedly performing an operation of manually compressing the tube 40 to push out the air existing in the tube 40 or in the opening 21. .

  Then, as the predetermined period elapses, the dyeing liquid 2 is sucked up to the inside of the wood 10 by the water absorption action of the wood 10 and the inside of the wood 10 is dyed. During the staining period, the staining solution 2 can be replenished from the injection port 36 of the staining solution container 30 as necessary. In the present embodiment, when the dyeing period is about 2 weeks and the lumber 10 is then sawn, the beautiful wood 10 that is sufficiently dyed to the inside can be obtained while taking advantage of the natural grain. Further, the dyed color was darker than the original color of the dyeing liquid 2 because the dyeing liquid 2 was not diluted by water absorption from the roots. In addition, it was confirmed that the coloring as originally intended was almost realized. That is, in this embodiment, since the dye liquid supply tools 20 having different colors are arranged at some distance from each other, they are stained according to the positional relationship in which the dye liquid supply tool 20 is arranged without being mixed. Observed. Moreover, since the opening part 21 used the fan-shaped dyeing liquid supply tool 20, the same color was dye | stained by the wide area.

  Note that the staining solution supply tool 20 is not limited to the one in which the opening 21 is formed in a fan shape as described above, and for example, the staining solution supply tool 20 having the nozzle portion 27 can be used. In this case, the hole portion 16 is drilled in the mouth end surface 11 with an electric drill or the like, the staining solution supply tool 20 is driven into the nozzle portion 27, and the staining solution 2 is supplied into the wood 10 from here. can do. As the dyeing liquid supply tool 20 having such a nozzle part 27, for example, a nut coupler joint as shown in FIG. 3A can be used. In this case, the tube 40 and the staining solution supply tool 20 can be simply and reliably connected by simply inserting the nipple portion 28 of the staining solution supply tool 20 into the tube 40 and tightening the nut portion 29 to the nipple portion 28. it can.

  In this embodiment, as shown in FIG. 3B, a total of six holes 16 into which the staining liquid supply tool 20 having the nozzle portion 27 is inserted are arranged at substantially equal intervals on the same circumference of the sap material portion 21. The case where it drills is illustrated. A total of six staining solution supply tools 20 inserted into the respective holes 16 are provided with tubes having three-way joints 45 from three staining solution containers 30 each containing a different staining solution 2. Through 40, the dye liquid 2 of each color is supplied to the two holes 16 that are not adjacent to each other. Other processes such as coating of the coating agent and connection with the tube 40 are the same as those described above.

  When the staining liquid supply tool 20 having such a nozzle portion 27 is used, the surface parallel to the wood end surface 11 of the wood 10 is dyed concentrically with the hole portion 16 as the center. Moreover, compared with the case where the dyeing liquid supply tool 20 which has the fan-shaped opening part 21 is used, the area of the end surface 11 which receives the supply of the dyeing liquid 2 from one dyeing liquid supply tool 20 becomes small. Thereby, for example, the dyeing method of the present invention is applied to a kind of wood 10 in which the dyeing liquid 2 is difficult to penetrate in the radial direction, and the dyeing liquid supply tool 20 is arranged by examining the dyeing position while visually checking the end face 11. By providing this, it becomes possible to express more detailed and complicated patterns.

  As described above, according to the staining method of the present embodiment, the staining solution supply tool 20 can be disposed while actually viewing the end face 11. Thereby, the boundary of the sap part 12 and the core part 13 can be confirmed, and the dyeing | staining liquid 2 can be supplied only to the sap part 12 which can be dye | stained. Further, even in the case of the wood 10 having a cavity inside, the staining liquid supply tool 20 can be disposed avoiding the cavity, and the staining liquid 2 can be prevented from being washed away through the cavity. In addition, since it is easy to set a desired color arrangement at a desired position using a plurality of staining solutions 2, accidental elements can be reduced and coloring intended to some extent can be performed by staining.

  Further, the air contact surface 15 of the mouth end surface 11 is coated with a coating agent, and the conduit and the phlegm tube are closed, so that the force to absorb moisture from the outside is only on the portion in contact with the staining solution supply tool 20. It acts and the dyeing liquid 2 is sucked in more effectively. Moreover, since evaporation of moisture from the air contact surface 15 can be suppressed, it is possible to suppress depletion of the felled wood 10 and to maintain the suction of the dyeing liquid 2 that greatly depends on the transpiration activity for a predetermined period. Become.

  Furthermore, by using the dyeing liquid supply tool 20 in which the opening 21 is formed in a fan shape, the dyeing liquid 2 can be supplied to the end face 11 in a wide area, and the wood 10 can be dyed efficiently. In addition, since it has a fan shape, the dyeing liquid supply tool 20 can be arranged along the annual ring, and the sapwood portion 12 can be efficiently dyed, and the pattern of the annual ring unique to the wood 10 is utilized. Dyeing can be performed. Moreover, since the thin peripheral part 22 is formed in the edge of the opening part 21, the staining liquid supply tool 20 is driven into the end face 11, and the peripheral part 22 is bitten into the end face 11, so that the peripheral part 22 and the end face are 11 can be attached without any gap. Thereby, the dyeing liquid 2 becomes difficult to leak to the outside, and the dyeing liquid 2 can be effectively used and supplied to the wood 10 from the end face 11.

  Further, the dyeing liquid supply tool 20 having the fan-shaped opening 12 and the dyeing liquid supply tool 20 having the nozzle part 27 are different in how the wood 10 is dyed, and can be colored with different textures. . That is, various dyeings can be performed by arranging the dye liquid supply tool 20 having an appropriate shape at a desired position with a desired color scheme.

  Moreover, since the felled timber 10 is dyed, all the parts above the felling site can be used, and the yield is good. In addition, it is possible to use the thinned wood or the timber 10 that is vegetated in a place with poor scaffolding, which contributes to effective utilization of resources. Further, since there is no water absorption action from the roots as in the case of dyeing standing trees, the dyeing liquid 2 can be sucked up exclusively, and the dyeing liquid 2 is diluted or the dyeing liquid 2 is lost to the soil through the roots. There is no fear and dyeing can be performed efficiently.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements can be made without departing from the scope of the present invention as described below. And design changes are possible.

  For example, in the present embodiment, the dyeing liquid supply tool having a fan-shaped opening and the dyeing liquid supply tool having a nozzle portion are illustrated as being attached to separate woods, respectively. However, the present invention is not limited thereto. It is also possible to use a combination of both types of dye solution supply tools for the same wood. Thereby, it becomes possible to perform further various dyeing | staining.

  Further, in the present embodiment, the case where the staining solution supply tool is arranged on the surface of the mouth by separating the staining solution to some extent is illustrated, but the staining solution supply tool of different colors is disposed in close proximity on the surface of the mouth, thereby dyeing. It is also possible to form a gradation pattern in which the colors are mixed at the part where both colors come into contact with each other due to liquid permeation. Of course, the setting of the type of wood to be dyed, the number of dyeing liquid supply tools, the number of colors of the dyeing liquid, the color scheme, and the dyeing position is not limited to those exemplified in this embodiment, and these are set in various combinations. Therefore, it is possible to carry out various dyeings. Further, the dyeing period is not limited to that exemplified in the present embodiment, and can be set as appropriate according to the ease of dyeing liquid penetration, the diameter and length of the wood, etc., depending on the properties of the wood to be dyed.

  In addition, the configuration of the staining solution container and the configuration in which the staining solution supply tool and the staining solution container are connected can be used in this embodiment as long as the staining solution is introduced from the staining solution container to the staining solution supply tool. It is not limited to what was illustrated. For example, a connection part and a tube in which no groove part is formed on the outer periphery can be fastened using a hose band. Moreover, it can also be set as the structure by which a dyeing liquid container is directly attached to a dyeing liquid supply tool, without passing through a tube. In the present embodiment, the procedure for disposing the staining solution supply tool on the mouthpiece surface, connecting the staining solution supply tool and the tube, connecting the tube and the staining solution container, and filling the staining solution container with the staining solution Although an efficient one is shown so that the staining solution does not leak from the unconnected portion, this procedure is of course exemplary. That is, each operation may be performed in any order as long as the staining liquid is introduced from the staining liquid container to the staining liquid supply tool and the staining liquid can be supplied to the wood from the mouth end.
