Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a Japanese paper-style decorative material and a method for producing the same.

More specifically, the present invention relates to a high-quality decorative material having a texture of Japanese paper and a pattern such as a texture, and a method for producing the same, and the decorative material can be used as, for example, a ceiling material.

(Prior Art) Japanese paper is widely used for fusuma etc. because of its soft and unique texture.

When a textured pattern is applied as a print pattern to this Washi paper, the texture of the Washi paper and the texture of the Washi paper are harmonized, and both are utilized to further enhance the sense of quality.

By the way, the fabric is originally formed by knitting and weaving threads, and has extremely fine irregularities on the surface. As a result of the unevenness, an extremely delicate change occurs due to the difference in the shadow depending on the viewing angle and the angle of light reflection, and a sense of quality is generated due to the three-dimensional effect of the thread.

When such a cloth pattern is printed with a grid pattern with lines drawn vertically and horizontally on the edges, it is not possible to reproduce the three-dimensional effect of the fabric, and it is also possible to express partial fading of the fabric due to shadows and light reflection angles. I can't.

(Problems to be Solved by the Invention) Therefore, the present invention is a method for producing a high-quality printing decorative material that can reproduce the fine three-dimensional effect, partial blurring, and the like of a fabric by printing, and is very similar to the fabric. The object is to provide a cosmetic material that can be obtained.

(Means for Solving the Problem) In order to solve this problem, the invention of claim (1) is such that a Japanese paper and a rayon nonwoven fabric having a basis weight of 10 to 50 g / m ² are laminated in this order on a decorative material base material. A rayon non-woven fabric surface is provided with a printing pattern, and a Washi-style decorative material is provided.

Further, the invention of claim (3) is characterized in that after laminating a Japanese paper and a rayon non-woven fabric having a basis weight of 10 to 50 g / m ^2, a print pattern is applied from the rayon non-woven fabric side, and then laminated on a decorative material base material. The present invention provides a method for producing a Washi-style cosmetic material.

According to the object of the present invention, when the printed pattern is a textured pattern, the high-grade feeling of the decorative material is particularly utilized.

(Function) The rayon nonwoven fabric according to the present invention is made by making rayon fibers into paper, and is extremely thin and has voids (fiber-free portions) in partial and random portions. Therefore, the printed pattern applied from the non-woven fabric side is partially formed on the non-woven fabric and also partially formed on the Washi paper or the adhesive layer provided under the non-woven fabric. Both are randomly and extremely finely arranged.

Since the non-woven fabric surface and the surface of the Washi paper or the adhesive layer thereunder are not in the same plane but have a height difference, a three-dimensional effect can be expressed by the pattern applied to both.

In addition, the printing pressure applied at the time of printing differs between the non-woven fabric surface and the Washi paper or adhesive surface due to the height difference, so a clear pattern is formed on the non-woven fabric surface and a faint pattern on the Washi paper or adhesive layer surface. Is formed. Due to the difference in the pattern, a subtle taste can be expressed by the reflection angle of the light of the shadow of the cloth.

As described above, since the rayon nonwoven fabric is extremely thin and is obtained by making paper, it has the texture of Japanese paper, and it is also visible through the nonwoven fabric. Therefore, it has the texture of Japanese paper as a whole.

As a result, the texture of Japanese paper and the faint printed pattern with a three-dimensional effect are harmonized, and a high-class and entertaining cosmetic material is obtained.

Embodiments Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 of the drawings is an explanatory sectional view showing an example of a decorative material of the present invention.

In FIG. 1, (1) shows a decorative material base material. The decorative material base material (1) serves as a structural support for the entire decorative material, and it is necessary that the decorative material base material (1) has rigidity according to the application of the decorative material. When using a decorative material as a ceiling material, lightweight plywood is desirable. Corrugated cardboard, a honeycomb core or a foamed sheet on which another sheet is laminated, a particle board, or the like can also be used depending on the application.

(2) is Japanese paper. The Japanese paper (2), together with the nonwoven fabric (3), imparts a Japanese paper-like texture to the decorative material and serves as a support for the nonwoven fabric (3) during printing. For this reason, Japanese paper having a basis weight of 30 to 60 g / m ² is desirable.

As the Japanese paper (2), in addition to Japanese paper made from Kozo, Mitsumata, etc., paper made by mixing 10 to 50% by weight of N paper and L paper with waste paper can be used. The waste paper is mixed for the purpose of hiding the decorative material base material (1) so that it cannot be seen through from the surface of the decorative material.

(3) is a non-woven fabric. Since it is necessary to have partial, random, and fine voids, it is necessary to use a non-woven fabric having a coarse basis weight of 10 to 50 g / m ² .

Further, in order to form the printed pattern (4) clearly, a non-woven fabric obtained by randomly arranging rayon non-woven fabrics is used. The rayon fibers may be randomly arranged, or partially bundled with rayon fibers. The bundle of mixed rayon fibers is arranged on the surface of the non-woven fabric (3), so that a high-class feeling can be improved. Gold yarn or silver yarn may be used instead of the rayon fiber bundle.

The Japanese paper (2) and the non-woven fabric (3) can be laminated via the adhesive (2a). The adhesive (2a) also serves the purpose of sealing the Japanese paper (2), and a method of applying it on 5-20g / m ² (dry) Japanese paper (2) and superposing the non-woven fabric (3) on it is integrated. preferable.

Since the printed pattern (4) is also formed on this adhesive (2a), the adhesive (2a) is preferably hydrophobic. Further, in order to facilitate coating adhesion, it is preferable to use water as a solvent. Such an adhesive is an emulsion type,
For example, an ethylene-vinyl acetate copolymer emulsion adhesive can be used.

The printed pattern (4) is applied after the Japanese paper (2) and the non-woven fabric (3) are laminated. This is because the nonwoven fabric (3) alone cannot withstand the tension of the printing machine, and it is necessary to apply the printing pattern (4) to the adhesive (2a) and the nonwoven fabric (3) at the same time.

The printed pattern (4) is applied from the side of the nonwoven fabric (3).
This is because the adhesive (2a) and the non-woven fabric (3) are printed at the same time, and based on the difference in height, the non-woven fabric (3) is printed clearly and the adhesive (2a) is printed in a faint tone.

For this reason, printing is preferably performed by a printing method in which ink is transferred by printing pressure. That is, gravure printing, flexographic printing, and the like.

Further, it is desirable that the printed pattern (4) is a texture. This is because the three-dimensional effect of the non-woven fabric (3), the faint tone of the printed pattern (4) and the texture of the Japanese paper (2) are harmonized, and a cosmetic material full of interest can be obtained.

After forming the printed pattern (4), the surface of the Japanese paper (2) is laminated on the decorative material substrate (1). Lamination can be done via an adhesive (1a). The adhesive (1a) may be any one, but it is preferable to use water as a solvent because it is easy to handle. Examples thereof include emulsion-type adhesives such as ethylene-vinyl acetate copolymer, water-soluble adhesives such as starch, and mixtures thereof. The adhesive agent (1a) is applied to the decorative material substrate (1), and then the surface of the Japanese paper (2) is overlaid and integrated.

A transparent paint (5) having excellent abrasion resistance can be applied to the surface of the decorative material. For example, it is a one-component or two-component curing type urethane paint.

It is desirable that the amount of transparent paint (5) applied should not exceed 8 g / m ² (dry). This is because the unevenness of the surface of the non-woven fabric (3) is lost and the designability is impaired. When used as an interior material such as a ceiling material, it is desirable to apply 3 g / m ² (dry) or more to improve the surface height.

(Effects) As described above, according to the present invention, the printed pattern has a three-dimensional effect, the concave portions are faint and the convex portions are clear, and the Japanese paper-like decorative material is beautiful in harmony with the texture of Japanese paper. Can be obtained.
