Description

The present invention relates to a repair method for damaged shoji paper and documents.

  Conventional repair methods such as damaged shoji paper and documents are performed by pasting repair paper on the damaged part. In this conventional method, there are problems such that the repaired portion is conspicuous and the thickness of the pasted paper is increased. In particular, the repaired part where paper is pasted deteriorates the appearance and impairs the aesthetics of the shoji. Also, the method of pasting paper requires time and effort to cut the repair paper into a star shape, a round shape, a rectangular shape or the like.

JP-A-11-224384, fiber mixing glue This patent relates to a fiber mixing glue for repairing a shoji tear. Mix fine fibers of paper pulp with starch paste, etc., apply this to the broken part of the shoji, and dry it to repair the shoji by connecting the fine fibers.
Japanese Patent Laid-Open No. 2001-115119 This patent relates to a paste in which paper fibers are melted. As in Japanese Patent Application Laid-Open No. 11-224384, the paste is applied on the part where the shoji is torn, and is applied with a spatula, and then spread and repaired. The glue is contained in a vinyl container, and a spatula is attached to this container. When painting, support the back of the shoji with a flat plate.

The problem to be solved by the present invention is to make the repair part of the broken shoji as inconspicuous as possible. As described above, the background art has a problem in that the conventional method greatly impairs the beauty of the Japanese paper shoji and takes time and labor, such as cutting repair paper. There are two major problems in the prior art. First, when paste is applied to the entire surface of the repair portion and dried, the opaqueness and color tone of the unique visible light that the Japanese paper paper has lost. Specifically, the portion where the glue is applied is more visible than the portion where the glue is not applied, so that the visible light is more transparent, and the repaired portion becomes conspicuous. For this reason, the color tone of the shoji paper changes, and the aesthetics of the Japanese shoji paper are impaired in the same manner as when repair paper is pasted. The same applies when fine fibers are mixed. In addition, when the fine fibers are mixed with the paste, the fine fibers are aggregated in the paste, and in fact, it is very difficult to uniformly disperse the fine fibers into the paste. When the proportion of fine fibers is small, this agglomeration is unlikely to occur. However, when the proportion is small, the role of joining by fine fibers is lost. Moreover, it is actually very difficult to apply the fine fiber mixed paste to the broken shoji. This is because the mixed fine fibers are unevenly gathered at one place, and it becomes impossible to apply a uniform thickness. In addition, if you use a spatula, etc., this unevenness will be more likely to occur.
In the present invention, in order to solve these problems, the glue is improved and the repair method is improved.

  Unlike the above-mentioned prior art documents, the means for solving the problem is that only the end surface (fracture surface) of the tear paper is applied to the place where the repairing glue is applied, and a composite paste that matches the color of the tear paper is used. There is to use. Also, presser paper is used to improve the flatness of the repaired part.

  The present invention does not require the repair paper to be pasted on the torn paper screen, and has an effect that the repaired portion can be restored to the state before the paper paper is damaged. It can be repaired without compromising the beauty of the Japanese paper shoji.

The figure explaining the implementation method of this invention The figure which shows the gluing part of the tear paper part of this invention

A mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 shows a procedure for repairing torn shoji paper. (A) shows the shoji frame 1 and the broken shoji part 2. (B) shows the top view and side view which affixed the transparent presser plate 4 with the adhesive tape 3 on the back surface of the tear shoji. (C) shows the gluing repairing part 5 in which glue is applied only to the end face of the tear paper. (D) shows the surface where the presser paper 6 is pasted on the paste. (E) shows the state of the repair completion part 7 when the transparent pressing plate on the back surface and the pressing paper on the front surface are peeled off.
The procedure of FIG. 1 will be described in further detail. The torn shoji part in (a) shows a damaged state when the pendant is broken with a pen or the like. For example, a plate made of vinyl chloride or the like is used as the presser plate 4 attached to the back surface. As the adhesive tape 3 to which this is applied, a tape having a weak adhesive force is used because it will be peeled off later. When applying the glue only to the end face of the shoji paper of the torn shoji screen, it becomes easier to apply the glue if the tear shoji portion is lifted a little. After application, the tear paper is stretched flat and only the edge of the paper is adhered as shown in (c). The presser paper 6 to be affixed onto the adhered tearing paper of (d) may be thin Japanese paper or normal office paper, but it may be ordinary paper. Use thin paper that is easy to absorb moisture in the glue. Along the tear line, stick it with your hand. Usually, it takes about 4 hours to dry the glue, and the presser paper 6 pasted after about 4 hours is peeled off by hand. The presser paper adheres to the composite glue, but can be easily peeled off by hand due to the small adhesion area. Thereafter, the transparent pressing plate 4 on the back surface is peeled off to complete the repair. Finally, the repair completion part 7 can be restored until almost no repair mark remains.

The paste to be used is not an ordinary paste for shoji paper pasting, but a paste (mixed paste) that is opaque to visible light. Specifically, for example, a paste mixed in a volume ratio of commercially available starch paste 100, commercially available vinyl acetate adhesive 10 for woodworking, and white watercolor paint 1 is preferable. This mixed paste is characterized by being able to obtain the opacity and color tone with respect to visible light, in which the repaired portion is the same as shoji paper by mixing at this volume ratio. For this reason, it is possible to return the repaired part to an almost infinite state before repairing. Vinyl acetate mixed with starch paste has the effect of eliminating ring spots. When the starch paste is used alone, it is easy to form ring spots when applied to the torn portion of the shoji paper. The torn paper is usually aged, and there is adhesion and penetration of dust (dust) on the paper surface and inside. The dust is extracted from the shoji paper by the action of water in the water-soluble glue, and has a problem of diffusing along the surface of the shoji paper. Dust that has diffused on the surface diffuses with drying, gathers at the ends, and becomes a phenomenon of so-called ring spots that remain as spots. This wheel jimi greatly detracts from the beauty of Japanese paper shoji. As a result of experiments, it has been found that this ringing can be prevented by mixing starch paste and vinyl acetate resin adhesive. The reason for this is considered that the mixed vinyl acetate resin adhesive has a role of preventing moisture diffusion. Since the affinity between moisture and vinyl acetate is very high, moisture stays only within the range of glue applied. Also, in the case of only vinyl acetate adhesive without starch paste, the strength and hardness of the vinyl acetate resin after drying is high and the characteristics are different from those of shoji paper. .
A small amount of white watercolor paint is added to eliminate the transparency of the glue. In old shoji screens, a small amount of brown watercolor paint can be mixed with white watercolor paint to make the tone more suitable for the current color of shoji paper. As a result, the glue has the same degree of opacity and color tone as visible paper for visible light. Therefore, the repaired part maintains the same aesthetics as before repairing.
As described above, the component of the composite paste is composed of three kinds of mixtures of the main material, the moisture diffusion suppressing material, and the color tone adjusting material. The main material is, for example, starch paste, the moisture diffusion suppressing material is, for example, a vinyl acetate adhesive, and the color tone adjusting material is, for example, a white watercolor paint. The hybrid paste is preferably not water-soluble but water-soluble. This is because, in the case of an adhesive using an organic solvent system as a solvent, the phenomenon that the organic solvent diffuses on the surface of the shoji paper is more likely to occur than in the aqueous system. For this reason, ring spots are more likely to occur in the case of organic solvent systems than in water systems.

Example 1
A first embodiment will be described with reference to FIGS. 1 and 2. In Example 1, as composite material, a paste paper paste paste manufactured by Asahi Pen Co., Ltd. was used as the main material. Also, as a moisture diffusion suppressing material, a bond for woodworking (40% vinyl acetate resin, 60% water) made by Daiso Sangyo Co., Ltd., which becomes transparent when dried, was used. For the color tone adjustment material, white watercolor paint from Daiso Sangyo Co., Ltd. was used. These three kinds of materials were mixed at a ratio of the main material 100, the moisture diffusion suppressing material 10, and the color tone adjusting material 1. For the mixing, a plastic container and a glass stirring bar for mixing were used. Stir mixing is completed within 1 minute. Using this composite paste, repair was carried out according to the procedure shown in FIG. The application of the hybrid paste was performed only on the end face of the tear paper sheet, more specifically, on the end face 9 of the fracture surface shown in FIG. In the figure, the fracture end face 9 is shown thicker than it actually is. For the application, a circular fine brush No. 0 from Daiso Sangyo Co., Ltd. was used. A small amount of mixed paste is applied to the tip of the brush, and the mixed paste is applied only to the end surface 9 of the broken part of the shoji paper. It is preferable not to apply to the surface of the shoji paper and the opposite side of the fractured portion 10 against the opposite side. Although it may be applied, when the amount of glue increases, the finished appearance is poor. FIG. 2B shows the glue repair portion 5 in a state where the end faces of the tearing shoji are bonded together. In this state, the hybrid paste has not yet been dried, but since the moisture diffusion inhibitor is mixed, the diffusion of moisture in the paste is suppressed.

  Prior to applying the composite paste to the end face 9 of the broken part of the broken shoji paper in FIG. 2 (a), the holding plate 4 was attached to the back face of the shoji with cello tape. A transparent vinyl chloride plate having a thickness of 0.5 mm was used as the press plate. A material that is transparent and has releasability from the paste is suitable for the press plate. Since the hybrid glue is water-soluble, most resin materials do not have adhesiveness. Moreover, it does not attack the resin material. There are other reasons for using a transparent material for the holding plate. A broken shoji can usually be restored by adhering the end faces as it is, but in the case of a damage that has been partly lost and has a hole, apply the shoji paper to the damaged part and mold it. Repair by the method of the present invention. When this presser plate is attached to the back of the shoji paper, paper coated with a slightly adhesive may be used, but commercially available ordinary cello tape is suitable. As shown in FIG.1 (b), it is sufficient to stop about 4 points | pieces of a holding plate with a cellophane. The cellulosic tape does not change its adhesive strength after about a day, and can be easily peeled off. On the other hand, paper coated with a fine adhesive may adhere to shoji paper over time and damage the shoji paper when peeled.

  For the presser paper 6 in FIG. 1D, ordinary Japanese paper shoji paper was cut and used. The presser paper has a role of absorbing moisture in the glue and a function of flattening a small amount of glue that is raised on the surface. The presser paper was applied to the entire surface of the gluing repaired part immediately after bonding. After sticking, it was broken by hand and lightly pressed by hand along the eyes. By doing so, the bonding surface became flat. After 4 hours had passed, the dryness of the composite paste was confirmed by tactile sensation, and then the presser paper 6 and the presser plate 4 were peeled in this order to complete the repair. After the repair, as shown in FIG. 1 (f), the repaired portion could be restored to an inconspicuous state. It was difficult to visually confirm the repaired part from the distance as well as the distance.

(Example 2)
In Example 1, a part where the shoji paper was torn was torn off and repaired when a hole was opened. In this case, after repairing the torn part with no hole in the same manner as in Example 1, the part where the hole is opened is molded, and a pattern paper made of shoji paper having the shape of the hole is made. The pattern was pasted with its position aligned with the hole. As in Example 1, the glue was applied only to the end face of the pattern paper. The mixed glue, presser plate, presser paper, adhesive tape, etc. used are the same as those in Example 1. The pattern paper was made by using the transparency of the restraining plate 4 to mold the damaged hole of the tearing paper with natural light and cutting it with a pinch. An HB pencil that can be erased with an eraser was used for the watermark pattern making. In Example 2, the repair could be performed in the same manner as in Example 1.

  The present invention relates to repairing a Japanese-style shoji door, and is a technology that is less environmentally friendly and saves time and effort. The method of the present invention can be applied to the repair of general office documents in addition to the repair of shoji paper.
