Description

[Detailed Description of the Invention] This invention uses dyes without using pigments to give wood products clear coloring divided into two or more tones, and the unique beauty of the wood grain pattern is enhanced. This paper relates to a new dyeing and painting method for wood products that can freely express the appearance.

As is well known, when finishing various wood products such as wooden confectionery bowls, tea soba, flower vase stands, floorboards, and shellfish, a wooden base formed into the desired shape is coated in advance. By applying a dye to the transparent resin 1 after dyeing, it is possible to finish the surface of these wood products in a state in which the wood grain pattern is elegantly and clearly embossed.

However, when the above-mentioned dyeing process is performed by dividing two or more areas and coloring each area in a different tone, the dye bleeds through the fine pores in the wood fibers near the boundaries of the adjacent dyed areas. The dye that oozes out, especially from dark dyed areas to light colored dyeing, has a significant negative effect on the dyeing of light colored areas, ruining the beauty of the wood grain pattern in those areas. I'll put it away, so 9! In practical terms, it is considered impossible to express a woodgrain pattern that is divided into two or more tones on the surface of a woodwork product, and in normal cases, only one area is dyed with dye and the other area is dyed. was finished by painting with paint mixed with pigments.

The present invention is a method developed and developed to solve the above-mentioned problems, in which dyes of two or more colors are used on the surface of a wooden base formed into a desired shape, from light-colored dyed areas to dark-colored dyed areas. The dyeing process is sequentially applied to the first dyeing process, and in each of the dyeing processes, after the first dyeing process is completed, the surface of the dyed area is masked with a transparent resin paint, and then the next dyeing process is performed. 0 Hereinafter, the method of dyeing and painting wood products according to the present invention will be explained in detail with reference to drawings of examples. This shows an example in which a light-colored dye is used, and a dark-colored dye is used to dye the entire area around the upper surface and the lower surface in two different colors, and the entire surface is finished with a transparent resin paint. processed in the same order.

First, the wooden base (1) that will become the vessel is made of hard wood with beautiful grain and stable material, which is cut and polished into the desired shape using a potter's wheel or the like ('
Using the wood material (1) as shown in Figure 2) as a raw material, the light brown dye (2) is applied to the light-colored over-dyed area (2υ) at the center of the upper surface of this wood material (1), and the first dyeing is carried out as shown in Figure 3. After processing,
On the upper surface of the dyed area 61), a transparent resin paint (3) such as acrylic resin or polyurethane resin is applied.
Next, a masking process is performed to form a transparent coating film on the surface of the dyed part as shown in FIG. 4. Once the dyeing and masking process for the light-colored dyed area (71) is completed in this way, the entire upper and lower surfaces of the periphery of the wood material (1), that is, the dark-colored dyed area (b), are dyed with blackish brown. When the second dyeing process is performed using the dye (25) as shown in Figure 5, the light-colored dyed area 61 that is masked with transparent resin paint after the first dyeing process is covered with the second dyeing process. Since there is no fear that the black-brown dye (2F) used in the dyeing process of Dyed area: (Zl) is light brown, the dark dyed area '*es> is dyed blackish brown, and the two dyed areas ■l'')G!, 2) have wood grain patterns colored in different tones. When the above-mentioned processing is completed, a transparent resin (35) is applied to the surface of the second dyed area, that is, the dark dyed area (Z2) as shown in Figure 6. Apply or
Alternatively, although not shown in the drawing, all processing is completed by applying transparent resin paint (3j) to the entire surface of the vessel.

In addition, Minomoto explained an example in which the vessel body was dyed in 02 colors, light brown and blackish brown, but if the process is applied sequentially from the light dyed area to the dark dyed area, dyes of other tones can be used. The dyeing area can be divided into three or more areas to perform multicolor dyeing.

As described above, according to the method of the present invention, dyes are used without using pigments to give wood products clear coloring divided into two or more colors, and the unique beauty of the wood grain pattern is enhanced. Because it can be expressed freely, it has become possible to dye multiple colors using two or more colors, which was previously thought to be impossible.

If this is used for the finishing of various wood products such as wooden confectionery utensils, tea utensils, flower vase stands, floorboards, and other items for the home, it will exhibit optimal practical effects.

Claims (1)

[Claims] The surface of the wood substrate formed into a desired shape is dyed using two or more dyes in order from light-colored dyed areas to dark-colored dyed areas. A method for dyeing and painting wood products, characterized in that after completion of the dyeing process, the surface of the dyed area is masked with a transparent resin paint, and then the next dyeing process is carried out.
