Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention is for dyeing the interior of trees planted in plantations, gardens, parks, etc., or living in natural forests, etc., in any color or pattern. It concerns a method of dyeing raw wood.

``Conventional technology'' As a means of coloring living trees and trees after felling, there are methods of applying paint to the roots of living trees and starting with a desired color, and methods of standing trees after felling and press-injecting copper sulfate solution from the cut surface of the upper end. There are known ways to do this.

``Problems to be Solved by the Invention'' According to the above-mentioned conventional means, the inside of the tree is only uniformly colored, and there is a technical drawback that it is not possible to achieve high-level coloring, such as creating multicolored or monochromatic patterns on the cross section of the trunk, for example.

In addition, the above-mentioned conventional means involve applying a large amount of paint to the roots and using copper sulfate, which causes large-scale pollution.

The present invention provides a method for dyeing raw wood that overcomes the drawbacks of the above-mentioned conventional techniques.

``Means for Solving the Problems'' The present invention solves the above technical problems by forming dye solution holes in arbitrary positions of the trunk of live trees, which extend through the cambium and xylem of the trunk. A hole is drilled in the transverse direction of the trunk, and a dyeing solution part having a required head height from the injection port is provided, and a pipe is connected to the injection port, and the necessary dyeing solution is supplied to the dyeing solution hole, and the dyeing solution is This is a method for dyeing living wood, which is characterized by dyeing the interior of the living tree by absorbing the dye solution upward into the trunk through plant activity.

As an embodiment thereof, an insect repellent or a fertilizer solution may be added and mixed with the dyeing solution.

"Operation" The method for dyeing live wood of the present invention described above involves drilling a long dyeing solution hole in the trunk of a living tree and pressurizing the required dyeing solution into the dyeing solution hole.
The dye pores communicate across the cambium with a group of vascular ducts (or tracheids) that supply water from the roots to the leaves. The staining solution in the dyeing solution pores is supplied to the upper part of the trunk along with water from the roots through the connected conduits (or tracheids) and cambium, and the inside of the living tree above the dyeing solution pores is
Stained by a staining solution with increased absorption.

By arranging the dye holes in a criss-cross pattern, a lattice pattern, or a multi-color arrangement, it is possible to intentionally form a single-color or multi-color dye pattern inside the stem.

Since the method for dyeing green wood according to the present invention has the above-described structure, the dyeing solution does not leak or scatter on the outside or around the green tree, so there is no risk of causing pollution.

Furthermore, when the insect repellent or the dyeing solution added with the fertilizer solution of the above embodiment is used, they are absorbed into the upper part of the trunk along with the dyeing solution, so that the insect repellent dye can be produced and the fertilizer solution is efficiently absorbed. Ru.

"Example" Hereinafter, a detailed explanation will be given based on an example. First, referring to FIG. 1, which shows the dyeing apparatus of the first embodiment of the present invention, which was experimented with dyeing live cedar wood in a mountain forest, this embodiment shows that dyeing was carried out during the period from spring to autumn when plant activity is active. In the lower end and middle part of the trunk 1 of the living Japanese cedar, dyeing solution holes 2A2B, which are small circular holes (about 8 mm in diameter in this example), penetrate in a horizontal cross shape along the diameter of the trunk 1. The staining solution hole 2A2
The three ends of B are tightly fitted with seal plugs 4 to be closed in a liquid-tight manner, and the remaining end becomes an inlet 5 and is connected to a dyeing solution part 3, which will be described later, by a pipe 7. has been done.

Then, above the dyeing solution hole 2A2B, a dyeing solution section 3 consisting of a waterproof and dustproof type container 6 fixed to the trunk 1 is provided with a required head H (H in this embodiment = approximately 1 meter). The bottom of the staining solution section 3 and the injection port 5 are connected by a pipe 7, and a seal plug 4 through which the pipe 7 is passed is tightly fitted into the injection port 5, so that the staining solution hole 2A2B becomes liquid-tight with the outside air. , the dyeing solution in the dyeing solution section 3 pressurized by the head H is filled and supplied into the dyeing solution hole 2A2B.

Then, using this dyeing device, the stem 1 was dyed using the following method.
Internal staining was performed.

That is, first, a dye solution of a water-soluble dye of a desired color (a kimono dye is used in this example) is filtered and put into the container 6 of the dye solution section 3, and air is not left in the dye solution hole 2A2B. The dyeing solution under pressure was sent out and supplied to the dyeing solution hole 2A2B, and the dyeing process was carried out for about 6 months while replenishing the dyeing solution from time to time.

In this embodiment, the staining liquid hole 2A2B and the staining liquid part 3 are set at two locations, one at the base and the other in the middle of the stem 1, with the intention of improving the freshness of the dyeing and shortening the dyeing period.

The above experimental results show that a generally circular dyed pattern is formed on the cross section of the trunk 1 above the staining liquid hole 2A2B, and no matter which part of the dyed trunk 1 is cut, it is the same as the thick part of the trunk. The appearance of the pattern revealed the existence of the above-mentioned effect.

Next, another embodiment of the present invention will be described with reference to FIGS. 2 and 3.

That is, FIG. 2 shows another structure of the staining solution hole 2 according to the present invention, and FIG. The dyeing solution holes 2D are combined and arranged in a communicating manner. Figure 2 (B) shows an arrangement in which two parallel main dyeing solution holes 2C are connected to the dyeing solution holes 2D in a lattice shape with a fine pitch. So, this second
According to the results in Figures (A) and (B), clear staining of the inside of the raw wood can be expected.

In addition, Fig. 2(C) shows a pair of staining liquid holes 2A2B having T-shaped intersecting staining liquid holes 2A and 2B having individual staining liquid parts 3 (not shown) of different colors. , we can expect dyeing with a circular pattern consisting of a series of half-rings of different colors.

In addition, in FIGS. 2(D) and 2(E), the staining solution hole 2 is slightly inclined, and according to this inclined staining solution hole 2, the injection port 5
When filling the staining liquid from the inlet, the seal plug 4 at the end is located higher than the injection port 5 in the case shown in FIG. Residual air can be accurately and easily exhausted. In the case shown in FIG. 2(E), the dye hole 2 does not penetrate through the trunk 1, and
Since its terminal end is lower than the injection port 5, if the staining solution is gradually filled through the injection port 5, it becomes extremely easy to completely discharge the residual air.

On the other hand, in the embodiment shown in Fig. 3, two sets of three or four staining solution holes 2A group and 2B group are arranged so as to overlap each other with slightly different heights, and the upper and lower The stain liquid holes 2A2B are arranged alternately in the middle, and the stain liquid holes 2A group and the stain liquid hole 2B group are individually provided with stain liquid portions 3 of different colors.

According to the embodiment shown in FIG. 3, a rainbow-like pattern consisting of layers of rings of different colors can be created inside the living tree.

In addition, although the dyeing method of the present invention artificially supplies the dyeing solution, the dyeing process is a natural dyeing method based on the plant activity of the tree, so there is a correlation with the plant activity of the tree, and it is suitable for use in the spring when plant activity is active. Preferably from to autumn. The concentration and supply pressure of the dye solution must be selected taking into consideration the dyeing process period and the above-mentioned plant activity situation. For example, during periods of low temperature and weak plant activity, the pressure may be increased or the dyeing period may be increased. If the time is short, increase the concentration of the staining solution. However, since it is necessary to take care not to reduce or disturb tree plant activity, it is preferable to avoid head pressure of 1 meter or more and high concentration of dye solution.
The area ratio of the two groups of dye holes to the cross section of the trunk 1 is preferably 172 or less of the cross section line of the trunk 1.

Furthermore, the method for dyeing live trees of the present invention can be applied to all trees, regardless of the presence or absence of annual rings. However, the time required for staining trees without annual rings is qualitatively shorter than that of trees with annual rings.

"Effects of the Invention J As explained above, the method for dyeing live wood of the present invention makes it possible to dye the interior of a living tree in a single color or in a single color/multicolor pattern by utilizing the plant activity of the living tree. Since the freshness and shape of the dyeing and dyeing patterns can be artificially controlled, we can improve the value of wood and develop new uses by providing wood with colored cross sections that have not existed before. There are many benefits that can be achieved without the risk of developing symptoms.
