Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wood,

The present invention relates to a colorless wood and a method of manufacturing the same, and more particularly, to a colorless wood improved in three-dimensional embossing by imparting color (natural color) to a natural pattern of wood and a method of manufacturing the same.

Wood uses vary. The unique natural texture of wood can be seen as the greatest advantage of wood. In particular, the natural pattern of wood (wood grain pattern) increases the natural sense and aesthetic value. Accordingly, wood is mainly used for building materials such as flooring and wall finishing materials, ornaments, and furniture.

In general, wood products are processed so that the natural pattern of the wood, especially the natural wood grain pattern, can stand out. For example, in the case of plate products, natural veneer sheets are bonded to wood plywood to realize the natural wood grain of the wood. However, this requires a large amount of working water due to the bonding process of the natural veneer sheet and durability is degraded by aging or peeling of the natural veneer sheet.

As another example, in order to stand out the natural wood grain pattern of the wood, the surface of the wood is burnt through the heat treatment using a torch or the like to highlight the grain pattern of the wood itself, and then the wood surface is subjected to brushing, Thereby attaching the grain pattern three-dimensionally. For example, Korean Patent Laid-Open No. 10-2003-0076535 (Prior Art 1) discloses a technique related to this. However, this results in a difference in pattern depending on the degree of carbonization, for example, and there is a problem that the natural feeling is deteriorated due to carbonization.

In order to solve the problems of carbonization as described above, in Korean Patent No. 10-1385434 (Prior Art 2), a surface treatment agent containing soybean oil, sesame oil, cedar liquid, corn oil and charcoal powder is applied and dried, A technique capable of imparting natural feeling and stereoscopic feeling by brushing is proposed.

However, it is difficult to implement various colors in the prior art including the above-mentioned prior art documents. For example, when carbonizing with a torch or the like and applying a surface treatment agent containing charcoal powder as in the prior art document 2 as in the prior art document 1, the color is limited to a black color, It is difficult to do.

On the other hand, as a method of implementing color on wood, there is a method of applying color paint on the surface of wood. However, painting of color paints can achieve various colors depending on the choice of paints, but it drops the natural texture of wood. Above all, the painting of color paints is problematic in that the natural pattern (wood grain pattern, etc.) of the wood is lost due to the lamination of the paint layer, resulting in deterioration of natural feeling and aesthetic value.

In the present invention, the wood 100 may have a shape of, for example, a plate-like shape or a curved shape. For example, the wood 100 may be a single-layer plate or a multi- Lt; / RTI > In the accompanying drawings, for example, Fig. 2 shows a plywood to which three sheet materials 1, 2, and 3 are bonded.

The color red wood according to the present invention includes the wood grain pattern portion 10 and the ground pattern portion 20 as described above, and at least one of the wood grain pattern portion 10 and the ground pattern portion 20 is colored The liquid 30 'or 40' is permeated (absorbed) and is colored again. That is, at least one selected from among the grain pattern 10 and the ground pattern 20 is colored by the colored portions 30 and 40 re-colored by the penetration (absorption) of the color liquids 30 'and 40' Respectively. At this time, the grain pattern portion 10 and the ground pattern portion 20 have different colors.

In the present invention, 'different colors' are colors which are differently implemented by the colorants 30 'and 40', and / or colors of the colorants 30 'and 40' Means a color that is implemented differently by a unique color (natural color). Also, in the present invention, 'different colors' include not only different colors (colors) themselves, but also different colors (color densities) in the same color (color). For example, yellow and red, as well as different colors (colors) themselves, as well as dark yellow and light yellow color (color concentration) contains different things.

The red color portion 30 is formed only in the grain pattern portion 10 (see Fig. 2) by penetration (absorption) of the hue 30 'according to the first embodiment of the present invention, The red color portion 30 is formed only on the ground fringe portion 20 (refer to Fig. 5) by penetration (absorption) of the hue 30 'according to the embodiment.

Accordingly, the grain pattern 10 and the ground pattern 20 have different colors.

For example, in the case of the first embodiment of the present invention, the grain pattern portion 10 has a hue embodied by the hue 30 ', and the ground pattern portion 20 has a hue Natural color) and different colors are implemented. In the second embodiment of the present invention, the grain pattern portion 10 has the inherent color (natural color) of the wood 100, and the ground pattern portion 20 has the color So that different colors are implemented. In the third embodiment of the present invention, the grain pattern 10 and the ground pattern 20 have colors realized by different colorants 30 'and 40', and different colors are implemented .

In the present invention, 'color re-coloration' means that the coloring liquids 30 'and 40' penetrate (absorb) into the wood 100 and are colored (colored), which is different from the conventional painting of a color paint. Specifically, the painting of a typical color paint means that a color paint layer is laminated on the surface of the wood, but the color of the color in the present invention is the color liquid 30 '(40 ') Is penetrated, absorbed and colored. In the present invention, the re-colored portions, that is, the re-colored portions 30 and 40 are portions formed in the grain pattern portion 10 and / or the ground pattern portion 20 at a predetermined depth, ) 40 'is penetrated (absorbed). In addition, the re-coloring portions 30 and 40 have a color implemented by the coloring liquids 30 'and 40', which is different depending on the type of the coloring liquids 30 'and 40' May have the same hue as the coloring liquids 30 ', 40' themselves, or may have a different color from the used hueing liquids 30 ', 40'.

In the present invention, the coloring liquids 30 'and 40' are liquids containing a coloring agent and a solvent, and are not particularly limited as long as they can penetrate (absorb) the wood 100 and realize colors.

The coloring agent is not limited as long as it is a material capable of realizing hue, and it can be selected from an inorganic substance, an organic substance and / or an inorganic-organic compound, and the like. The coloring agent may use one or more selected from, for example, chemical dyes, chemical pigments, vegetable dyes and animal dyes. The colors realized by the coloring agent, that is, the colors of the re-coloring portions 30 and 40 may be, for example, brown, green, black green, black, purple, green, yellow, red, pink, And / or sky blue. These colors may be realized by mixing one kind of coloring agent or two or more kinds of coloring agents having different colors.

The ground tinted portion 20 is a part growing mainly in spring and summer and has a soft (soft) density lower than that of the grain pattern portion 10 and has a soft color (in most cases, close to white) . The present invention utilizes the inherent physical properties and hue of the wood 100 as described above.

2 (b), when the coloring liquid 30 'is applied to the surface of the wood 100 as described above, the grain pattern 10 and the ground fringe 20 have a penetration depth (T ₁ ) (T ₂ ). Specifically, when the coloring liquid 30 'is applied, the grain pattern 10 is hard and has a high density so that the penetration depth T ₁ of the coloring liquid 30' is small and the ground pattern 20 The penetration depth (T ₂ ) of the color liquid 30 'is large because of its smoothness and low density. That is, in FIG. 2B, T ₁ <T ₂ . Herein, T ₁ is the depth of the hue 30 'penetrated (absorbed) into the grain pattern 10, T ₂ is the depth of the hue 30' penetrated (absorbed) into the ground tinted portion 20, to be.

The coloring liquid 30 'is infiltrated (absorbed) into the grain pattern 10 and the ground pattern 20 as described above and then the surface of the colored wood 100 is subjected to brushing. At this time, in the brushing process, the penetrated portion of the tint 30 'of the ground tint 20 is etched and removed. 2 (b) and 2 (c), the surface of the grain pattern portion 10 and the ground pattern portion 20 are brushed, and the coloring liquid 30 'of the ground pattern portion 20 The penetrated part is etched and removed by brushing. That is, in FIG. 2 (b), the portion indicated by T ₂ is completely removed.

In the present invention, the brushing process is a process of etching the surface of the wood 100 by using, for example, a metal brush. In this brushing process, the hard wood grain 10 is etched a little , And the soft ground pattern 20 should be relatively etched. 2C, after the brushing process, the re-colored portion 30, which has been re-colored by the penetration of the coloring liquid 30 'into the grain pattern portion 10 only at the predetermined depth T ₃ And the portion where the hue 30 'is penetrated disappears in the ground tint 20.

In addition, a concavo-convex structure is formed on the surface of the wood 100 by the brushing process. 2 (c), the grain pattern portion 10 is formed on the ground pattern portion 20 so that the soft ground pattern portion 20 is etched relatively more than the hard wood pattern portion 10, So that the surface of the projected convexo-concave structure is formed. A red colored portion 30 having a predetermined depth T ₃ is formed on the protruding portion of the grain pattern portion 10. Accordingly, the color of the grain pattern portion 10 is realized by the penetration of the coloring liquid 30 ', and the ground pattern portion 20 has a natural color (natural color) 10) 20 are conspicuous and have a three-dimensional effect. At the same time, the grain pattern portion 10 is substantially protruded, and has an excellent three-dimensional embossing feeling.

FIG. 4 illustrates an exemplary embodiment of a brush unit 210 (220) in which the present invention may be implemented. In one example, the brushing process may be implemented through the brushing units 210 and 220 as shown in FIG. 4 is a perspective view and a plan view of the brush units 210 and 220 according to an embodiment of the present invention.

Referring to FIG. 4, the brush units 210 and 220 have a plurality of brushes 215 and 225, respectively. The brush units 210 and 220 are installed on the conveying means 110, which etch the surface of the wood 100, for example, by rotation. According to a preferred embodiment, the brushing units 210 and 220 include a cup type first brush unit 210 installed at the rear end of the re-coloring processor 130, And a second brush unit 220 of a roll type.

The cup-shaped first brush unit 210 includes a cup brush 215 having a metal wire 215a and a rotating shaft 212 mounted on the cup brush 215 to transmit rotational force . At this time, as shown in FIG. 4, a plurality of the cup brushes 215 are arranged in a zigzag form. In addition, the cup brushes 215 may be arranged in a zigzag arrangement in a single row, for example, in one to five rows. FIG. 4 illustrates a configuration in which zigzag arrangement is arranged in three rows. The roll type second brush unit 220 may include a roll brush 225 provided with a metal wire 225a and a support frame 222 for supporting the roll brush 225. [ As shown in FIG. 4, the roll brushes 225 may be arranged at equal intervals as a plurality of roll brushes 225. The cup brush 215 and the roll brush 225 are rotated, and they can be rotated by a motor (not shown), for example.

When the brushing units 210 and 220 include the cup-shaped first brush unit 210 and the roll-shaped second brush unit 220 as described above, the brushing process is improved. At this time, the cup brush 215 installed on the cup-shaped first brush unit 210 first bristles the surface of the wood 100, and is mainly responsible for the etching process. The roll brush 225 installed on the second brush-type brush unit 220 brushes the surface of the wood 100 to form a second brush, which is responsible for uniform etching.

The wood 100 passes through the brushing units 210 and 220 while being conveyed on the conveying means 110, for example, continuously in the rightward direction of FIG. At this time, the wood 100 passes by, for example, the brush units 210 and 220 by the conveying means 110 at a speed of 0.1 to 1.0 m / sec. The brush units 210 and 220 are spaced apart from the re-color processor 130 by a distance of 5 to 30 m. At this time, it may be different according to the conveyance speed of the wood 100. However, if the separation distance of the brush units 210 and 220 from the re-color processor 130 is less than 5 m, the penetration time of the hue solution 30 ' (Absorption) amount and / or penetration (absorption) depth (T ₁ ) (T ₂ ) can be lowered. If the separation distance of the brushing units 210 and 220 exceeds 30 m, for example, the process line may be long and may not be preferable in terms of space utilization. In consideration of this point, it is preferable that the brushing units 210 and 220 are spaced apart from the re-coloring processor 130 by a distance of 8 to 20 m.

The distance may also be applied to the dryer 150. Specifically, the dryer 150 described above may be installed between the re-coloring processor 130 and the brushing units 210 and 220 and / or the rear ends of the brushing units 210 and 220. In this case, In the case of being installed between the processor 130 and the brush units 210 and 220, the spacing distance may be applied. That is, when the dryer 150 is installed between the re-coloring processor 130 and the brushing units 210 and 220, the dryer 150 is spaced from the re-coloring processor 130 by 5 to 30 m And may be spaced apart from each other by a distance of preferably 8 to 20 m. The reason is as above. In particular, if the distance between the dryer (150) is too short, the drying time is shortened and the penetration time of the coloring liquid (30 ') is shortened. And if the spacing of the dryer 150 is too long, for example, the process line may be long and undesirable in terms of space utilization.

The spacing distance may refer to the distance from the end (or the center) of the re-coloring processor 130 to the entrance (or center) of the brushing unit 210, 220 or the dryer 150. Further, according to one embodiment, the coloring liquid 30 'can be infiltrated (absorbed) for about 10 seconds to 5 minutes (infiltration time) by controlling the feeding speed of the wood 100 and the spacing distance have.

Meanwhile, according to another embodiment, the manufacturing method of the present invention may further include a sanding process for sanding the surface of the wood 100. The sanding process may be performed using, for example, a sand paper. At this time, the sanding process may be performed before the color remover process and / or after the brushing process. To this end, one or more sanders 120 may be installed at the tip of the re-color processor 130 and / or at the rear end of the brush units 210 and 220. FIG. 3 illustrates a state in which one sanding machine 120 is installed at the tip of the re-color processor 130. The sanding machine 120 may have a structure in which sandpaper is attached to the surface of a rotating roller, for example.

 The sanding process before the re-coloring step smoothes the surface of the wood 100 (surface homogenization), for example, uniformly applying and penetrating the coloring liquid 30 'during the red coloring step. In addition, the sanding process after the brushing process smoothes the surface of the wood 100, and improves the surface and the beauty of the red-colored wood, for example.

Further, in the present invention, each of the processes is at least one time. That is, the re-coloring step, the brushing step, the drying step and / or the sanding step may be performed only once, or may be repeated several times, if necessary. Further, according to another embodiment of the present invention, the brushing process may be performed before the color re-coloring process. For example, the manufacturing method according to the present invention may sequentially include a brushing process, a colorizing process, and a brushing process.

The brushing process may be as long as it allows the hard wood grain pattern 10 to be slightly etched and the soft ground pattern 20 to be relatively etched so as to have a concavo-convex structure on the surface of the wood 100 . That is, the grain pattern 10 may protrude from the ground pattern 20. Specific examples of such a brushing process include those described in the first embodiment. To this end, one or more brushing units 210 and 220 may be installed at the tip of the re-coloring processor 130. The brushing units 210 and 220 may be the same as those described with reference to FIG. 4 in the first embodiment. Same as.

The coloring liquid 30 'is applied on the surface of the brushed wood 100 to penetrate and absorb the coloring liquid 30' from the surface of the wood 100 to a predetermined depth T ₁ (T ₂ ) . At this time, as described in the first embodiment, the grain pattern portion 10 and the ground pattern portion 20 show a difference in penetration depth (T ₁ ) (T ₂ ) due to a difference in inherent property. Specifically, when the coloring liquid 30 'is applied, the grain pattern 10 is hard and has a high density so that the penetration depth T ₁ of the coloring liquid 30' is small and the ground pattern 20 The penetration depth (T ₂ ) of the color liquid 30 'is large because of its smoothness and low density.

 The coloring liquid 30 'is infiltrated (absorbed) in the grain pattern portion 10 and the ground pattern portion 20 and the surface of the colorized wood 100 is polished. At this time, in the polishing step, the penetrated portion of the coloring liquid 30 'of the grain pattern portion 10 is etched and removed. Specifically, the surface of the grain pattern portion 10 and the ground pattern portion 20 are polished, and the portion of the grain pattern portion 10 in which the coloring liquid 30 'is penetrated is etched and removed through polishing. This polishing process is as described in the second embodiment. That is, the polishing process is a process of etching the surface of the wood 100 to a predetermined thickness, which can at least etch away the penetrated portion of the second coloring liquid 30 'of the grain pattern 10 And is not particularly limited.

In the polishing step of the third embodiment, the grain pattern 10 and the ground pattern 20 are etched (sanded) to the same thickness so that the surface irregularity structure is maintained. That is, the portion of the wood grain 10 which is penetrated by the hue 30 'is etched and removed so that the concave-convex structure protruding from the ground pattern 20 is maintained. The portion of the ground tinted portion 20 in which the hue 30 'is penetrated is not deeply etched and removed, but remains at a predetermined depth.

Therefore, the reddish-colored part 30 of the reddish-colored wood according to the third embodiment protrudes from the ground-tinted portion 20 and only the ground tinted portion 20 has a predetermined depth T ₃ . The grain pattern portion 10 has a natural color (natural color) of the wood. In other words, the ground tinted portion 20 realizes color due to the penetration of the coloring liquid 30 ', and the grain pattern portion 10 has a natural color (natural color) ) 20 is prominent and has a three-dimensional effect. At the same time, the grain pattern portion 10 is substantially protruded, and has an excellent three-dimensional embossing feeling.

The brushing process, the red coloring process, and the polishing process may be performed, for example, through the brush units 210 and 220, the color re-coloring processor 130, and the polishing machine 160, respectively. Specific configurations of the brushing units 210 and 220, the color re-coloring processor 130, and the polishing machine 160 are the same as those described in the first and second embodiments.

The wood 100 sequentially passes through the brushing units 210 and 220, the re-coloring processor 130 and the abrasive machine 160 while being carried on the conveying means 110, for example, continuously. At this time, the conveying means 110 conveys the wood 100 at a speed of 0.1 to 1.0 m / sec. The grinding machine 160 is spaced apart from the re-coloring processor 130 by a distance of 5 to 30 m. However, if the separation distance is less than 5 m, the penetration time of the hue solution 30 'may be shortened so that the penetration (absorption) amount and / or the penetration (absorption) depth may be lowered. If the separation distance exceeds 30 m, for example, the process line may be long and may not be preferable in terms of space utilization. In consideration of this point, it is preferable that the abrasive machine 160 is spaced apart from the re-color processor 130 by a distance of 8 to 20 m.

As described above, the dryer 150 may be installed between the re-color processor 130 and the polisher 160 and / or the rear end of the polisher 160.

The reason is as described above. In particular, if the distance between the dryer (150) is too short, the drying time is shortened and the penetration time of the coloring liquid (30 ') is shortened. And if the spacing of the dryer 150 is too long, for example, the process line may be long and undesirable in terms of space utilization.

On the other hand, in the third embodiment, as described in the first embodiment, it is possible to further include a sanding process in which the surface of the wood 100 is sanded and smoothed. The sanding process may be performed using, for example, a sand paper. At this time, the sanding process may be performed before the color remover process and / or after the polishing process. To this end, one or more sanders 120 may be installed at the tip of the re-color processor 130 and / or the rear end of the grinder 160.

The sanding process before the re-coloring step smoothes the surface of the wood 100 (surface homogenization), for example, uniformly applying and penetrating the coloring liquid 30 'during the red coloring step. In addition, the sanding process performed after the polishing process smoothes the surface of the wood 100, for example, can further improve the surface and beauty of the red-colored wood.

7 (a) and 7 (b), a first color liquid 30 'is first applied on the surface of the wood 100 to form a first color 30' from the surface of the wood 100 to a predetermined depth, The grain pattern portion 10 and the ground fringe portion 20 are deformed by the penetration depths of the grain pattern portion 10 and the ground pattern portion 20 due to the difference in inherent physical properties as described in the first embodiment, Respectively. 7 (b), when the first coloring liquid 30 'is applied, the grain pattern 10 is hard and has a high density, so that the penetration depth of the first coloring liquid 30' The ground tinted portion 20 is soft and has a low density, so that the penetration depth of the first coloring liquid 30 'is large.

  The first coloring liquid 30 'is infiltrated (absorbed) into the grain pattern 10 and the ground pattern 20 as described above to perform the first color re-coloring process, and then the surface of the first color- . At this time, in the polishing step, the penetrated portion of the first hue layer 30 'of the grain pattern 10 is removed by etching. 7 (b) and 7 (c), the surfaces of the grain pattern 10 and the ground pattern 20 are polished, and the first color liquid 30 'of the grain pattern 10 is polished, ) Is etched and removed through polishing. This polishing process is as described in the second embodiment. That is, the polishing process is a process of etching the surface of the wood 100 to a predetermined thickness, which can at least etch away the penetrated portion of the second coloring liquid 30 'of the grain pattern 10 And is not particularly limited. By this polishing process, the grain pattern portion 10 and the ground pattern portion 20 are etched (sanded) to the same thickness, and the wood 100 has a flat surface. At this time, the portion of the grain pattern 10 penetrated by the first coloring liquid 30 'is etched and removed, but the portion of the grounding pattern 20 where the first coloring liquid 30' And is left at a predetermined depth without being completely etched or removed.

7C, after the polishing step, the first red colored portion 30 re-colored by the penetration of the first color liquid 30 'into only the ground tinted portion 20 has a predetermined depth And the portion of the grain pattern 10 where the first coloring liquid 30 'is infiltrated is eliminated. In addition, the surface of the wood 100 is flattened by the polishing process. That is, the grain pattern portion 10 and the ground pattern portion 20 have a flat surface without protruding.

Next, a second color liquid 40 'is applied on the surface of the polished wood 100 to penetrate and absorb the second color liquid 40' from the surface of the wood 100 to a predetermined depth. (Second Re-coloring Process) As described above, the grain pattern portion 10 and the ground pattern portion 20 show differences in penetration depth due to the difference in inherent properties. 7 (d), when the second color liquid 40 'is applied, the grain pattern 10 is hard and has a high density, so that the penetration depth of the second color liquid 40' And the ground tinted portion 30 is soft and has a low density, so that the penetration depth of the second coloring liquid 40 'is large. At this time, as shown in FIG. 7 (d), the penetration depth of the second color liquid 40 'is set so as not to be deeper than that of the first red colored portion 30 re-colored by the penetration of the first color liquid 30' (Absorbed).

The second colored liquid 40 'is infiltrated (absorbed) into the grain pattern 10 and the ground pattern 20 as described above to perform the second color re-coloring process and then the surface of the second colored red colored wood 100 Is brushed. At this time, in the brushing process, the second colored liquid 40 'of the ground tinted portion 20 is etched and removed. 7 (d) and 7 (e), the surfaces of the grain pattern 10 and the ground pattern 20 are brushed, and the second color liquid 40 'of the ground pattern 20 is ground, This penetrated part is thoroughly etched and removed by brushing. This brushing process is as described in the first embodiment. The brushing process causes the hard grain pattern 10 to be etched a little and the soft ground pattern 20 to be relatively etched so that the second color liquid 40 ' The penetrated portion may be completely etched and removed, and the first red colored portion 30 formed on the ground tinted portion 20 may be formed so as to be left to a predetermined thickness. This can be implemented, for example, by adjusting the pressing force of the brush units 210 and 220.

As shown in FIG. 7E, after the brushing process, the first re-colored portions 30, which are re-colored by penetration of the first color solution 30 ', are formed in the ground tinted portion 20 to a predetermined depth And the second red colored portion 40 is formed in the grain pattern portion 10 to a predetermined depth by the penetration of the second color liquid 40 '. In addition, a concavo-convex structure is formed on the surface of the wood 100 by the brushing process. 7 (e), the grain pattern portion 10 is etched relatively to the ground pattern portion 20 so that the soft ground pattern portion 20 is etched relatively more than the hard wood pattern portion 10, So that the surface of the projected convexo-concave structure is formed. Accordingly, the color of the ground tinted portion 20 is realized by the penetration of the first coloring liquid 30 ', and the color of the grain patterned portion 10 is realized by the penetration of the second colored liquid 40' , And the natural patterns (10) and (20) are prominent due to the difference in color upon visual observation, thereby having a three-dimensional effect. At the same time, the grain pattern portion 10 is substantially protruded, and has an excellent three-dimensional embossing feeling.

The first and second re-color processes may be performed through the first and second re-color processors 130, respectively. The polishing process and the brushing process may be performed through the polishing machine 160 and the brushing units 210 and 220, respectively. The specific configurations of the first and second re-color processors 130, the grinder 160, and the brush units 210 and 220 are the same as those described in the first and second embodiments.

The wood 100 is transferred from the first re-color processor 130, the grinder 160, the second re-color processor 130, and the brush unit 210 while being loaded on the transfer means 110, for example, (220). At this time, the conveying means 110 conveys the wood 100 at a speed of 0.1 to 1.0 m / sec. The abrasive machine 160 is spaced apart from the first re-color processor 130 by a distance of 5 to 30 m. The brush units 210 and 220 are spaced apart from the second re-color processor 130 by a distance of 5 to 30 m. The penetration time of the first coloring liquid 30 'and the second coloring liquid 40' is shortened so that the amount of penetration (absorption) and / or the amount of penetration (absorption) of the first coloring liquid 30 ' Or penetration (absorption) depth may be lowered. If the separation distance exceeds 30 m, for example, the process line may be long and may not be preferable in terms of space utilization. The grinding machine 160 and the brushing units 210 and 220 may be spaced apart from the first and second re-coloring processors 130 by a distance of 8 to 20 m, respectively.

As described above, it is preferable that the distance between the first re-color processor 130 and the grinder 160, between the grinder 160 and the second re-color processor 130, between the second re-color processor 130 and the brush unit 210 A dryer 150 may be installed between the first re-color processor 130 and the abrasive machine 160 and / or between the first re-color processor 130 and the abrasive machine 160, and / Or in the case of the dryer 150 installed between the second re-color processor 130 and the brush units 210 and 220, the spacing distance may be applied. That is, when the dryer 150 is installed between the first re-color processor 130 and the grinder 160, and / or between the second re-color processor 130 and the brush units 210 and 220, 150 may be spaced apart from the first and second re-color processors 130 by a distance of 5 to 30 m, preferably spaced apart by a distance of 8 to 20 m. The reason is as described above. Specifically, if the distance between the dryer 150 and the first coloring liquid 30 'is too short, the drying time is shortened and the penetration time of the first coloring liquid 30' and the second coloring liquid 40 'is shortened. And if the spacing of the dryer 150 is too long, for example, the process line may be long and undesirable in terms of space utilization.

On the other hand, in the fourth embodiment, as described in the first embodiment, it is possible to further include a sanding process in which the surface of the wood 100 is sanded and smoothed. The sanding process may be performed using, for example, a sand paper. At this time, the sanding process may be performed before the first colorizing process and / or after the brushing process. To this end, one or more sanders 120 may be installed at the front end of the first re-color processor 130 and / or at the rear end of the brush units 210 and 220.

 The surface of the wood 100 is planarized (surface uniformized) by, for example, uniformly applying and penetrating the first coloring liquid 30 'during the first reding step, . In addition, the sanding process performed after the brushing process smoothes the surface of the wood 100, thereby further improving the surface and beauty of the red-colored wood.

In addition, the manufacturing method according to the fourth embodiment may further include a brushing step optionally performed before the first colorizing step. For example, in the manufacturing method according to the fourth embodiment, the first brushing process-> the first reding process-> the polishing process-> the second reding process-> the second brushing process are sequentially included . At this time, the first brushing step brushes the surface of the wood 100 to make the hard wood grain pattern 10 etched a little and the soft ground pattern 20 a relatively large etched, Any material that can have a concave-convex structure in the wood 100 may be used. That is, the grain pattern 10 may protrude from the ground pattern 20 before the first re-color process. The specific embodiment of the first brushing process includes the portion described in the first embodiment.

According to the present invention described above, an improved coloring wood can be provided. In particular, according to the present invention, as described above, the wood pattern 100 and / or the ground pattern 20 of the wood 100 are colored, and the wood pattern 10 and the ground pattern 20 Have different colors, and the natural patterns 10 and 20 of the wood 100 are prominent and have a three-dimensional appearance. In addition, when the grain pattern 10 protrudes, the natural patterns 10 and 20 become more conspicuous, and the three-dimensional emboss feeling is remarkably improved. In addition, various colors can be implemented in the natural pattern 10 (20). That is, a desired color can be variously implemented according to the selection of the coloring liquids 30 'and 40' on at least one selected from the grain pattern portion 10 and the ground pattern portion 20.
