Description

[Detailed Description of the Invention] (Industrial Application Field) Wooden products that have a unique texture due to grass dyeing and are used as architectural materials such as wall panels and floorboards, and accessories such as brooches and bracelets, and their production. It is about the method.

(Conventional technology) It has been practiced since ancient times to dye fabrics woven from linen, cotton, etc. using dyes from plants that grow naturally in the mountains, but the technology to apply this dyeing technique to wood has yet to be developed. It has not been.

The inventor spent many years researching prototypes to develop a dyeing technique for wood, and has now completed a manufacturing method suitable for mass production.

(Problems to be Solved by the Invention) The gist of this invention is to dye the surface of a wooden material with a decoction of mugwort grass that grows naturally in the mountains and fields, thereby coloring the grain of the wood and the green color of the mugwort grass. The purpose is to provide a novel wood product that has a unique, astringent texture that is well-balanced, and a method for producing the same.

As mentioned above, in order to make use of the grain of the wood, harmonize well with the green color of the mugwort grass, and produce wood products with a unique astringent texture, it is necessary to collect fresh mugwort grass and infuse it. In addition to making soup (dye liquid), a mordant liquid is also created by diluting iron sulfate, etc. with water.

Then, the wooden surfaces of teacups, plates, etc. that have been cut using a machine such as a potter's wheel are pre-dyed with the above-mentioned dye solution, then the wooden surfaces are dyed with the above-mentioned mordant solution, and then the wood surface is dyed again with the above-mentioned dye solution. After dyeing, the wood is thoroughly dried, a base coat of urethane is applied to the dried wood surface, and the finish is applied after polishing.

(Example) Hereinafter, an example of the method for manufacturing grass-dyed wood products according to the present invention will be described in detail. Wood products such as tea cups and plates are produced by cutting materials such as horse chestnut and zelkova using a potter's wheel or the like. to create a wood base of the desired shape.

In addition, we collect fresh mugwort grass, which has been used for food and medicinal purposes since ancient times, and put the mugwort grass and water in a container to make a decoction (dye liquid). Aqueous solution of mordant added to water at around S-g% (mordant solution)
Make each.

Next, the surface of the wood, which has been cut into a desired shape from horse chestnut, zelkova, etc., is pre-dyed with the dye solution described above.

At this time, it is appropriate to dye the yarn about 3 times, and if dyeing is performed multiple times, it is preferable to do it when the previous dyeing is 70% dry.

In this way, the dye liquid will penetrate into the interior of the wood and the dyeing will be carried out sufficiently.

After the above-mentioned yarn dyeing operation is completed, the wood surface yarn-dyed as described above is dyed with the above-mentioned mordant liquid.

This causes the dye in the dye to develop color, making the wood grain stand out and creating shading on the surface of the wood.

Thereafter, the wood surface that has been dyed with the mordant solution to develop color is piece-dyed with the above-mentioned dye solution in the same manner as the pre-dyeing process/~S times, and is thoroughly dried.

Next, a urethane coating is applied to the wood surface dyed as described above, and after polishing with sandpaper or the like, a finishing paint, such as a urethane paint, is further sprayed (see Fig. 1).

Note that decorations such as patterns are done after the final piece dyeing is completed.

(Operations and Effects) The grass-dyed wood product and its manufacturing method of the present invention are as described above, and in the grass-dyed wood product, not only does the dye not peel off, but the wood grain of the wood and the green color of the dye solution are different from each other. It has a unique texture with a bitterness that has never been seen before.

In addition, according to the manufacturing method of this invention, the green decoction (dye liquid) of mugwort grass harmonizes well with the grain of the wood material cut from horse chestnuts, zelkova, etc., resulting in an unprecedented astringency. It is possible to easily produce wood products with a unique texture and dyes that do not peel off.

Mugwort grass grows naturally in the mountains and fields, is easy to collect, and is non-toxic, making it ideal as a dye for wood products often used as kitchen utensils.

Furthermore, the mordant is a decoction of mugwort leather, that is, it has the effect of coloring the pigment in the dyeing solution, and by using this mordant, the effect of highlighting the grain of the wood and the shading of the color tone can be achieved conveniently. be.

Furthermore, yarn dyeing with a dye solution has the effect that the dye solution penetrates into the inside of the wood so that the dye does not peel off, and piece dyeing with a dye solution has the effect of bringing out the wood grain on the surface of the wood.
