Dyed wood -IRODORITAI-

IRODORITAI is a registered trademark of the Dyed wood of the NAKAMURA TSUKIITA INC.
 IRODORITAI (I want to color it) is our Dyed veneer, Dyed veneer laminated wood, Dyed wood, generic name of the Dyed fancy plywood. It was more fun by interior and I hung "○○ tai "of the end of a word that was one of the dialects of Fukuoka and named it brightly as it was our thought" "which I wanted to color and company of Fukuoka. (it has been registered a trademark)
 In fact, in our country, Japan, the forest cover for the country is pushed in spite of forest large country of the second place of the world with 67% by imported lumber having cheap imported lumber, an individual color; and of the domestic lumber effectively utilizing it did not advance too much. Meanwhile, I paid my attention to the domestic lumber including a cedar, the hinoki which had not been effectively utilized taking into consideration the current situation that came to have difficulty in acquisition of the imported lumber year by year too much until now by log export of each country regulation to prevent indiscriminate hunting and I dyed it and provided high quality of wood materials of the added value, and which has begun to wrestle in this business from thought to want to produce the products that it could be to a replacement of the imported lumber which had an individual color.

Difference between Dyed wood and conventional coloration wood

 The Dyed wood colors it using dye according to the name unlike the wood which colored the surface it by postprocessing with the color system paint. A feel of texture thereby remains without a sticky impression without grain (grain of wood) being destroyed. In addition, it depends on the condition of the materials such as thickness, length, the tree class, but it is a big difference with the color system paint that a color remains in the wood inside as a color penetrates even if I sharpen the surface with an NC router and a woodwork lathe, a plane as rear processing.
 Allergic reactions may be usually caused depending on a person as the paint of the color system is oiliness. On the other hand, the Dyed wood uses aqueous dye of the human body no damage. I am usually reliable as it is the thing which was developed to dye clothing.
In addition, it is a color pro-characteristic that the light and shade of the color appear because the arrival at of molecules of the dye is not necessarily same  to lasting fat and cellulose, hemicellulose, ingredient such as the lignin of the wood. (cf. lower photograph)
Difference with the color system painting

Dyed wood judging from a video

 It is a video when I cut a cedar and the hinoki which I dyed in thickness planer, table saw, panel saw. As you see I think that you can confirm what a color spreads among to the wood inside. Aiming at improvement of the dyeing processing technique, I will update a video irregularly in future.

  • I am doing it on the basis of the color mentioned above. I can make the color except the above by changing the density of dye, and mixing plural number-colored dye. (e.g., red black = brown)
  • It may be different from a real color by the lighting of a monitor and color setting, the room of the PC which a customer uses.

About dye to use

The dye to use was developed to usually dye clothing and can use it with a thing of the human body no damage in peace.
I impregnate dye by vacuum pressurization to add a color to wood well.

Option (urethane coating)

I accept urethane coating to Dyed wood with an option. Luster appears, and color development family names increase when I give the painting.
※I can see the whole of the photograph each when I slide by the boundary line of the before, after photograph. 


  • For the dyeing to a nature material, a hue, grain of wood, the feel are different one by one.
  • For a quality of wood ingredient (cellulose, hemicellulose, lignin), thickness, length, fat under the influence of a tylosis, a straight-grained board, the cross grain, a hydrous rate of the complete color to the wood inside please note that may not penetrate.
  • Uneven coloring may occur.
  • I note drying enough, but a curve, torsion, breaking may occur.
  • On storage, you avoid high temperature and humidity, and please keep it in the air permeable good shaded place.
  • As friction and the water wet are environment to do and discolor, I would like surface coating such as the urethane coating by all means.

Future possibility of the Dyed wood

Ebony black dyeing hinoki
The left, the ebony right, black dyeing hinoki
I can expect that the acquisition of materials with individual colors such as ebony or uenju will become more and more difficult by log export of each country regulation in future easily. Meanwhile, I believe it if I utilize a limited resource (domestic lumber) effectively and raise the plasticity of materials of the acquisition by the dyeing hard to please when I hide the possibility that it will spread as a relatively cheap replacement in future. Therefore we become the employee bullet and research and develop it for innovation every day.
※Please note that the sample becomes charged.
