2. Description of the Related Art Conventionally, a woven fabric in which gold threads, silver threads and the like are woven, a metallized woven fabric in which a metal is directly vapor-deposited, etc. are known.

[0003]

However, such a conventional metallized fabric is inferior in iris gloss, and is not only used for clothing but also for packaging, interior decoration, etc. There were drawbacks such as poor expressiveness with a single color.

Therefore, an object of the present invention is to solve the above-mentioned problems so as to provide a woven fabric excellent in color developability which overcomes the problems that conventional colors are monotonous and lacking in expressiveness and lacking in decorativeness. It is something to solve.

[0005]

In the interference iris vapor deposition fabric of the present invention, a first metal vapor deposition layer, a transparent compound vapor deposition layer, and a second metal vapor deposition layer are sequentially laminated on one side of the fabric, and the reflected light beam has an iris luster. Characterized by presenting.

As a result, in the above configuration, the first and second
By adjusting the thickness of the metal vapor deposition layer, an interference iris vapor deposition fabric having the desired iris luster was obtained.

In order to adjust the thickness of the vapor deposition layer, the interference iris vapor deposition fabric of the present invention is bonded to a fabric on which a transparent polyethylene terephthalate film having a thickness of 25 μm is vapor deposited, and at the same time as the fabric, a first metal vapor deposition layer, A transparent compound vapor deposition layer and a second metal vapor deposition layer were formed and used as samples for measuring the thickness of each vapor deposition layer.

A spectrophotometer (manufactured by Shimadzu Corporation, UV-365) is used to measure the visible light transmittance, and a first metal vapor deposition layer, a transparent compound vapor deposition layer, and a second metal vapor deposition layer are formed on one surface thereof. The visible light transmittance of each vapor-deposited layer of the transparent polyethylene terephthalate film sample having a thickness of 25 μm was measured.

The relationship between the visible light transmittance and the thickness of the metal vapor deposition film layer varies depending on the metal vapor deposited, but the average values of the results measured using aluminum as an example are shown in Table 1.

In detail, in the step of sequentially depositing the first metal vapor deposition layer, the transparent compound vapor deposition layer, and the second metal vapor deposition layer on one side of the fabric, the transparent compound vapor deposition layer that is laminated next to the first metal vapor deposition layer is reflective. Based on the principle of the type interference filter, the optical thickness (nd) is set to a layer thickness which is an odd multiple of ¼ wavelength, and the thickness of the second metal vapor deposition layer is such that the iris color can be further enhanced. Form.

With the above structure, the present invention has a mixed color tone of blue and gold when viewed from the front, but changes to a mixed color tone of green, blue and purple each time the viewing angle is changed by about 15 degrees. The feature was created and the iris color was beautifully reflected.

The fabric used for the interference iris vapor deposition fabric of the present invention is not particularly limited, and for example, a fabric of synthetic fiber monofilament, a fabric of synthetic fiber with modified cross-section yarn, a fabric of synthetic fiber multifilament, polyester film. , A woven fabric obtained by weaving slit threads obtained by finely cutting a polyamide film or the like.

The modified cross-section yarn can be made into a fiber having a modified cross-section such as a flat shape, a quadrangle, a triangle or a polygon by changing the nozzle for melt spinning. It is preferable because the flat yarn is vapor-deposited in a large area.

The polyester fiber woven fabric is previously used in an alkaline chemical (caustic soot) for applications requiring texture.
A woven fabric with a soft texture may be produced by weight reduction processing according to (d).

The first metal vapor deposition layer and the second metal vapor deposition layer used in the interference iris vapor deposition fabric of the present invention are, for example, A
l, Ni, Cr, Ti, Au, Ag, Cu, Pt, M
Simple metals such as o, Nb, Fe, Co, Ta, Zn, Mn, W, and Zr or alloys thereof are preferably used. Although the thickness of the metal vapor deposition layer depends on the metal used, the first metal vapor deposition layer needs a metallic reflection function, and thus the light transmittance at 500 nm is preferably 20% or less. The second metal vapor deposition layer may have a light transmittance of 40% or more at 500 nm for the purpose of clearly emphasizing optical interference.

The transparent compound vapor-deposited layer used in the interference iris vapor-deposited fabric of the present invention is not particularly limited.
O, ZnS, Al ₂ O ₃ , TiO, Ti ₂ O ₃ , Si
O, Sio ₂ , SiO _x , ZrO ₂ , Ta ₂ O ₅ , Sn
_{O 2, CeO 2, In 2} O 3 -SnO 2 (ITO), A
1N, Si ₃ N ₄ , SiC, MgF ₂ , BN, LaF ₃
Is used, and its thickness remarkably expresses the angle dependence of the reflected iris color, so the optical thickness (nd)
Is set to an odd multiple of 1/4 wavelength, a strong reflected iris color is obtained, and the reflected iris color is increased in proportion to the thickness of the transparent compound vapor deposition layer. However, regarding the quality of the laminated vapor deposition layer, when the thickness of the transparent compound vapor deposition layer is 500 nm or more, the internal stress becomes large and cracks occur in the laminated vapor deposition layer, and as a result, the reflected iris color becomes extremely weak. Further, at 100 nm or less, light interference was small. Therefore, it may be selected and combined from the range of 100 nm to 500 nm. Even more preferably, the reflected iris color changes strongly from the viewing angle of 150 to 400
A combination may be selected from the range of nm.

As the vapor deposition method of such metals and compounds, physical vapor deposition methods such as a vacuum vapor deposition method, a sputtering method, an ion plating method, a reactive vacuum vapor deposition method, a reactive sputtering method and a reactive ion plating method, or A chemical vapor deposition method or the like is used as appropriate.

The interference iris vapor-deposited fabric of the present invention is provided with a known undercoat resin layer by a conventional method in order to strengthen the adhesion of the first metal vapor-deposited layer, and further protects the second metal vapor-deposited layer. A publicly known overcoat resin layer may be provided.

The interference iris vapor-deposited woven fabric having the reflection gloss iris color thus obtained has an extremely excellent color developability by overcoming the drawbacks such as the lack of decorativeness in which conventional colors are monotonous and lacking in expressiveness. I got it.
