DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat foil yarn for a drawing foil, and more particularly to a novel flat foil thread for a drawing foil capable of weaving a beautiful woven fabric having an appearance similar to that of glass crafts and porcelain. is there.

[0002]

2. Description of the Related Art As is well known, one of the weaving techniques widely used in Japan since ancient times is a technique called "Hikihaku" or "Hikibaku".
According to Page, Tankosha Co., Ltd., the first edition issued on June 6, 1977, "Hikihaku-Draw foil-Gold foil, silver foil, etc. cut into thin flat foil using a spatula etc. to prevent twisting, Or insert a bamboo spatula etc. into the open shed, close it, hook a flat foil on the tip of the spatula, pull out the spatula while holding one end, the flat foil is squeezed with a spatula, It is inserted without twisting and shows a luster peculiar to metal because it is held down by warp. It is used for brocades and belts. "Design Training Paper Training Page, 148 pages, Nishijin Design Pattern Paper Cooperative, Heisei 7 According to a report issued on December 12, 2012, "Hikibaku-pulled foil-a technique in which a thinly cut foil slightly longer than the width of the fabric is hung on a cut portion at one end of a spatula and drawn into the warp opening. , Or its foil, characterized in that the foil is woven without turning over In the past, all were manual work, but recently there are also semi-automatic ones. "Further, Japanese Utility Model Registration No. 252432 discloses that" ... The foil 5 as a weft
Is formed by weaving the fabric 6 in a flat foil state without twisting the fabric 6 by a manual operation using a spatula or an automatic foiling apparatus ... ".

[0003] The history of the technique called "Hikihaku" or "Hikibaku" is very old, and as a result, the terms are confused at present, as in the above-mentioned documents. Is called "pulled foil", and the flat foil or foil cut finely is called "flat foil thread".

[0004] From the old days to the present, flat foil yarn that has been commonly used as a drawing foil is a gold foil (thickness of 3 to 4 µm),
Silver foil (thickness 4 to 8 μm), fired foil (the silver foil is discolored with hydrogen sulfide), brass foil (sometimes called western foil; thickness 7 to 8 μm), aluminum foil (thickness 7 to 8 μm)
8 μm) and a colored foil (the silver foil or the aluminum foil is colored and processed to a required color using a dye and a synthetic resin) to form a sheet-like material having a pattern formed using one or more metal foils. It is cut into strips 0.3 to 3 mm wide.

[0005] The most characteristic feature of the drawn foil is that, when a pattern is formed on the sheet-like material, a woven fabric reproducing the pattern can be woven.

For example, after a required pattern is formed on a gold foil surface of a sheet-like material in which gold foil is stuck on the entire surface of a Japanese paper for drawing foil, the sheet-like material is cut into narrow strips having a width of 0.3 to 3 mm. By pulling and weaving the filaments (plain foil yarns) one by one into the warp openings one by one, a woven fabric in which the pattern is reproduced can be woven.

[0007] Therefore, in the practice of drawing foil, efforts have been devoted to the formation of beautiful and varied patterns, and a number of techniques have been adopted. Can be

[0008] 1. A metal foil is stuck on the entire surface of the Japanese paper for drawing foil, and a sheet-like material having a required pattern drawn on the foil surface using lacquer or lacquer is cut into strips to obtain a flat foil thread.

[0009] 2. Various metal foil pieces (for example, gold foil pieces and silver foil pieces) are mixed and adhered to a Japanese paper for drawing foil, and a sheet-like material having a required pattern formed thereon is cut into a thin strip to obtain a flat foil thread.

[0010] 3. An adhesive is applied to a washi-foiled paper, placed on a surface of the adhesive, and crushed metal foil is scattered to cut a sheet-like material having a required pattern into thin strips to obtain a flat foil yarn.

4. Using a lacquer or lacquer directly on the washi-foil paper, the sheet-like material with the required pattern is cut into strips to make flat foil yarn.

5. A sheet-like material having a pattern formed by appropriately combining the above 1 to 4 is cut into a thin strip to obtain a flat foil thread.

In recent years, a method has been adopted in which a sheet-like material obtained by transferring a required pattern onto a washi-foiled paper using a hot stamping foil (transfer foil) is cut into strips to form flat foil yarn. A method in which this method and each of the above methods 1 to 5 are appropriately combined is also adopted.

Further, recently, there has been proposed a method in which various plastic films are used in place of the washi-foil paper, and a sheet-like material having a required pattern formed on the film by vapor deposition or printing is cut into strips to form flat foil yarn. Has been adopted.

[0015]

SUMMARY OF THE INVENTION The present invention has been engaged in the production of the above-mentioned various sheet-like materials used for flat foil yarn for drawing foil for many years. It has been studied as a technical problem to provide a flat foil yarn for a draw foil capable of weaving a beautiful woven fabric having an aesthetic sensation that cannot be obtained by the above-mentioned conventional various methods.

Further, the inventor of the present invention has found that when the above-mentioned various sheet-like materials are obtained by laminating two or three pieces of Japanese paper, the lamination may be peeled off when the sheet-like material is cut into strips. In order to solve the problem that defective products may occur and to form a band, a haori, etc. made of a fabric woven using the above-mentioned various conventional flat foil yarns for drawing foil, it is formed at the time of wearing or drying the insect. It has been studied as a technical problem to solve the problem of peeling and discoloration (burning of a foil) of a patterned pattern, particularly a pattern formed of metal foil.

In view of the above problems, at the stage when the various sheet materials are manufactured, the surface of the sheet material (the surface on which the pattern is formed by metal foil, metal foil pieces, sand particles, etc.) is coated with a resin. Is applied to form a transparent synthetic resin layer, and thereafter, a flat foil yarn for a thin foil is manufactured by a method of cutting into thin strips.

The present inventor has conducted numerous trial and error experiments and trial productions in order to achieve each of the technical problems described above.
μm transparent polyethylene terephthalate (hereinafter “PE
Looking at the surface of the film from the surface of the film with a pattern formed using gold foil on the back of the film, it looks as if it were a gold-plated glass craft called Ruri or Glass. I found a remarkable phenomenon that it looks like.

The present inventor was surprised at the above phenomenon, and while performing various processes on the sheet-like material, a white coating film was formed on the back surface (the surface on which the pattern of gold foil was formed) of the sheet-like material. When viewed from the surface of the film when viewed from the surface of the film, it looks like the appearance of a white porcelain that has been subjected to gilding, and when viewed from the surface of the film by forming a blue coating instead of a white coating And found that it looked like the appearance of a gilded celadon porcelain.

The present inventor has achieved the above-mentioned technical subjects as a result of repeated experiments and trial production based on the above-mentioned respective findings.

[0021]

The above technical objects can be attained by the present invention as described below.

That is, according to the present invention, one or two or more selected from gold foil, silver foil, fired foil, brass foil, aluminum foil and colored foil are provided on the back of a transparent PET film having a glossy surface and a thickness of 40 to 150 μm. After forming a pattern using the metal foil, a sheet-like material having a transparent or opaque synthetic resin coating formed on the entire back surface is cut into strips having a width of 0.3 to 3 mm. It is a flat foil thread for a draw foil.

In the present invention, a pattern is formed by using lacquer or lacquer on the back surface of a transparent PET film having a glossy surface and having a thickness of 40 to 150 μm.
After forming a pattern using one or two or more metal foils selected from a baked foil, a brass foil, an aluminum foil and a colored foil, a sheet-like material having a transparent or opaque synthetic resin coating formed on the entire back surface is treated as a 0. A flat foil thread for a drawing foil, which is cut into strips having a width of 3 to 3 mm and the surface of the film is turned to the front side.

The present invention also relates to a transparent PET film having a glossy surface and a thickness of 40 to 150 μm, on the back surface of which one or more selected from gold foil, silver foil, baked foil, brass foil, aluminum foil and colored foil are provided. After forming a pattern using metal foil, and further forming a pattern using lacquer or lacquer,
A flat foil thread for a drawing foil, wherein a sheet-like material having a transparent or opaque synthetic resin coating film formed on the entire back surface is cut into strips having a width of 0.3 to 3 mm and the surface of the film is turned to the front side.

In the practice of the present invention (each of the above-mentioned inventions), when forming a pattern on the back surface of the transparent PET film using the metal foil, the pattern can be fixed using an adhesive. .

The structure of the present invention will be described in more detail as follows.

The transparent PET film having a glossy surface and a thickness of 40 to 150 μm used in the present invention may be a commercially available product, such as Lumirror (trade name: Toray), Diafoil (trade name: Mitsubishi Rayon), Tetoron (Trade name: Teijin) etc., and required products can be selected from products of other manufacturers (Nimura Chemical, Toyobo, Unitika, etc.).

The expression "the surface is glossy" of the transparent PET film used in the present invention means that the surface of the film is a so-called mirror surface. The commercially available products are often mirror-like on both the front and back surfaces, but depending on the type, some surfaces have slightly lower gloss than the other surface, so when using such a film, It is necessary to use a surface with excellent gloss as the surface.

The thickness of the transparent PET film used in the present invention is important. When the thickness is less than about 40 μm, the above-mentioned phenomena are unlikely to occur. When the thickness exceeds about 150 μm, it is suitable as a flat foil thread for a thin foil. Is difficult to obtain. Preferably, the thickness is 60 to 90 μm, more preferably, the thickness is 70 to 80 μm.
Should be used.

The metal foil used in the present invention includes the above-mentioned gold foil (same as above), silver foil (same as above), baked foil (same as above), brass foil (same as above), and aluminum foil (same as above) used in the conventional flat foil for drawing foil. ) And colored foils (same as above). Note that a hot stamping foil having an aluminum vapor-deposited film formed thereon may be used as one type of aluminum foil.

In the present invention, a paint used for forming a transparent or opaque synthetic resin coating film is a commercially available aqueous synthetic resin paint, for example, an aqueous paint for Toa leather (trade name: manufactured by Toupe Co., Ltd.) or a paint spray for Asahipen leather. (Trade name: manufactured by Asahi Pen Co., Ltd.) or a commercially available oil-based synthetic resin paint, such as Pluscoat SV80 clear (trade name: manufactured by Wasin Chemical Co., Ltd.) or urethane tank (trade name: manufactured by Tanabe Chemical Industry Co., Ltd.).

The lacquer and lacquer used in the present invention are the same as those used in the above-mentioned various methods employed for forming a pattern of a conventional flat foil for a drawing foil. it can.

The adhesive used in the present invention is the same as the adhesive used for laminating a washi foil and a metal foil in the production of a conventional flat foil for a foil, and is a commercially available aqueous bond or varnish for paperwork. A neutral adhesive that does not discolor the metal foil.

The flat foil yarn for a draw foil according to the present invention is manufactured by the following steps using the above materials.

First step: The transparent PET film is cut into required dimensions (usually a rectangle of 45 cm × 60 cm).

Second step: The glossy surface of the cut transparent PET film is used as the front surface, and a required pattern is formed on the back surface using the metal foil. For forming a pattern with a metal foil, a method of mixing the above-described various metal foil pieces and pasting them with the adhesive, or a method of applying and applying the adhesive and scattering sand pieces of the metal foil on the adhesive surface alone are used. Or combine. It is to be noted that the present invention is not limited to these methods, and various well-known methods used for gilding using a metal foil can be adopted.

In the second step, prior to the formation of the pattern by the metal foil, the required pattern is drawn on the back side of the transparent PET film by hand-painting or spraying using lacquer or lacquer, and the pattern by the metal foil is placed thereon. The adhesive may be omitted when the lacquer or lacquer forms a pattern made of metal foil when it is not dried.

Further, in the second step, after forming a pattern with a metal foil, a desired pattern may be drawn thereon by hand-painting or spraying using lacquer or lacquer.

Third step: The above-mentioned water-based synthetic resin paint or the above-mentioned oil-based synthetic resin paint is applied to the entire back surface (the surface on which the pattern is formed) of the transparent PET film by brushing or spraying, and the transparent synthetic resin is coated. Either a film or an opaque synthetic resin film is formed into a sheet.
The thickness of the coating is preferably about 1 to 3 μm.

Fourth step: The dried sheet is cut into strips having a width of 0.3 to 3 mm by a flat foil slitting slitter, and the strips are kept as they are without being separated. In this state, the PET film is temporarily fixed on a backing paper with the surface (glossy surface) of the PET film facing up to obtain a flat foil thread for a drawn foil. At the time of use, the flat foil yarn for the drawing foil is peeled off one by one from the backing sheet one by one according to the usual method of the drawing foil, and the warp shedding is performed one by one with the surface (glossy surface) of the PET film on the front side. It is drawn into the department and woven.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A typical embodiment of the present invention is as follows.

A transparent PET film (Lumirror: trade name: Toray) having a glossy surface and a thickness of about 75 μm is 45 cm ×
Foil pieces obtained by cutting a 60 cm rectangle into a rectangular shape, applying a thin adhesive (commercially available aqueous bond for papermaking) on the entire back surface, and cutting a gold foil having a thickness of about 4 μm into 10 mm squares. A "cut stone") and a foil piece (same as above) obtained by cutting a 5 μm thick silver foil into 10 mm squares are arranged in a hazy shape and adhered, and crushed about 3 μm thick gold foil. The sand particles thus obtained were randomly scattered to form a pattern.

After the adhesive is naturally dried, a blue transparent lacquer (manufactured by Toupe Co., Ltd.) is sprayed on the surface on which the pattern is formed by using a corrugated paper with a spray gun to partially remove the wavy pattern. Formed.

After allowing the sprayed lacquer to air dry,
A clear water-based synthetic resin paint (water paint for East Asia leather: trade name: manufactured by Toupe Co., Ltd.) is applied by brush over the entire surface on which the pattern is formed, and naturally dried to a thickness of about 2
A sheet of a transparent synthetic resin film having a thickness of μm was formed.

FIG. 1 is a longitudinal sectional view schematically showing the structure of the sheet material obtained here.

When the sheet-like material obtained here is visually viewed from the surface of the film under sunlight, the sheet-like material has the same appearance as that of the glass-crafted product which has been subjected to the gilding process, and is formed on the back surface. We confirmed that the pattern was as if it was shining inside the glass body.

In place of the transparent water-based synthetic resin paint,
Except for using a white water-based synthetic resin paint prepared by adding a white pigment to the paint, the sheet-like material on which the white synthetic resin coating film obtained under the same conditions as above was formed was visually observed under sunlight. When viewed from the front side of the film, it had the same appearance as the gold-plated white porcelain, and it was confirmed that the pattern formed on the back side was as if it glowed through the glaze layer.

The present inventor believes that these phenomena are caused by the fact that a 75 μm thick transparent PET film having a glossy surface on the uppermost layer transmits and reflects light. .

Next, the sheet-like material obtained here was cut laterally using a flat foil cutting slitter to obtain 1,700 strips having a width of 0.3 mm.
While the sheet was still cut, the film was temporarily fixed on a backing paper with the surface of the film facing up to obtain a flat foil thread for drawing foil.

The obtained flat foil yarn for the drawing foil was peeled off one by one from the backing sheet according to the conventional method of the drawing foil, and the warp openings were successively made one by one with the surface of the film on the front side. The surface of the woven fabric woven by drawing in and weaving is reproduced with the pattern formed on the sheet-like material,
When the pattern was visually observed under sunlight, almost the same phenomenon as that of the sheet-like material was confirmed.

When the sheet-like material obtained here is visually viewed from the back of the film under sunlight, it has the same appearance as that of a glass-crafted product having been subjected to gilding, and is formed on the surface. The phenomenon as if the pattern shines in the glass body was confirmed.

Next, the sheet-like material obtained here was cut laterally using a flat foil cutting slitter to form a strip 1 mm wide.
70 pieces were obtained, and each strip was temporarily fixed to a mount with the surface of the film facing up in a cut state without being cut apart to obtain a flat foil thread for drawing foil.

The flat foil yarn for a drawing foil thus obtained is peeled off one by one from the backing sheet according to the conventional method of the drawing foil, and pulled into the warp opening one by one with the surface of the film on the front side. On the surface of the woven fabric woven by weaving, the pattern formed on the sheet-like object is reproduced. The same phenomenon was confirmed.

Example 2: Instead of a transparent oily synthetic resin paint,
A sheet was obtained in the same manner as in Example 1 except that a thin blue synthetic resin coating having a thickness of about 4 μm was formed using a thin blue oil-based synthetic resin coating prepared by adding a blue pigment to the coating.

When the sheet-like material obtained here is visually viewed from the surface of the film under sunlight, the sheet-like material has the same appearance as a gilded celadon, and the pattern formed on the back surface is as if it were. A phenomenon as if shining through the pigment layer was confirmed.

Next, the sheet-like material obtained here was used in Example 1.
In the same manner as described above, a flat foil yarn for a drawing foil is used, and the surface of the woven fabric woven in the same manner as in Example 1 using the flat foil yarn for a drawing foil according to the conventional method of the drawing foil is formed on the sheet-like material. When the pattern was visually observed under sunlight, the same phenomenon as that of the sheet was confirmed.

Example 3 A glossy surface having a thickness of about 70
μm transparent PET film (Tetron: trade name: Teijin)
Was cut into a rectangle having a size of 45 cm × 60 cm, and a flower pattern was formed on the rear surface thereof by transfer using a gold-colored hot stamping film (commercially available) obtained by applying a yellow transparent synthetic resin coating to an aluminum vapor-deposited film.

After forming an arabesque pattern by hand using vermilion lacquer around the flower pattern, the lacquer is naturally dried, and then a transparent water-based synthetic resin paint (Toa Leather Co., Ltd.) is applied over the entire surface on which the pattern is formed. Aqueous paint for water: Trade name: manufactured by Toupe Co., Ltd.), and a white water-based synthetic resin paint prepared by adding a white pigment is applied with a brush, and dried naturally to form a white synthetic resin film having a thickness of about 4 μm. To form a sheet.

FIG. 3 is a longitudinal sectional view schematically showing the structure of the sheet-like material obtained here.

When the sheet-like material obtained here is visually viewed from the surface of the film under sunlight, the sheet-like material has the same appearance as a gilded white porcelain, and the pattern formed on the back surface is The phenomenon as if it were shining through the pigment layer was confirmed.

Next, the sheet-like material obtained here was cut laterally using a slitter for cutting flat foil to form a thin strip 1 having a width of 3 mm.
70 pieces were obtained, and without cutting each strip apart, the film surface was temporarily fixed to the backing with the surface of the film kept as it was, and the flat foil thread for a drawing foil was obtained. In accordance with the conventional method, the surface of the woven fabric was sequentially peeled off from the backing sheet one by one, and the film was woven by pulling one by one into the warp openings and sequentially weaving the film in a state where the surface of the film was on the front side. The pattern formed in the sheet-like material was reproduced, and when the pattern was visually observed under sunlight, almost the same phenomenon as that of the sheet-like material was confirmed.

Example 4 A transparent synthetic resin coating film having a thickness of about 4 μm was formed using a transparent aqueous synthetic resin paint (aqueous paint for East Asia leather: trade name: manufactured by Toupe Co., Ltd.) instead of the white aqueous synthetic resin paint. Except for the above, a sheet was obtained in the same manner as in Example 3.

When the sheet-like material obtained here is visually viewed from the surface of the film under sunlight, the sheet-like material has the same appearance as that of a gilded glass craft, and a pattern formed on the back surface The phenomenon was as if it were shining in the glass body.

Next, the sheet-like material obtained here was used in Example 3.
In the same manner as described above, a flat foil yarn for a drawing foil is used, and the surface of a woven fabric woven in the same manner as in Example 3 using the flat foil yarn for a drawing foil in accordance with a conventional method of the drawing foil is formed on the sheet-like material. When the pattern was visually observed under sunlight, the same phenomenon as that of the sheet was confirmed.

[0069]

According to the present invention, if the flat foil yarn for a drawing foil according to the present invention is used,
In the practice of drawing foil, it has an aesthetic feeling that could not be obtained by various conventional methods (aesthetics arising from the appearance of gold-finished glass crafts and the appearance similar to the appearance of gilded white porcelain and celadon porcelain) A beautiful fabric can be woven.

The flat foil yarn for a draw foil according to the present invention has a thickness of 4 mm.
Since a transparent PET film having a thickness of 0 to 150 μm is formed on the front side, a band or a haori made of a woven fabric by using the foil is woven by using a conventional flat foil for various kinds of foil. It is more durable than those formed, and peeling and discoloration of the pattern formed of the metal foil (as described above) can be prevented as much as possible.

Further, the conventional flat foil yarn for drawing foil using the washi foil washi has a white cross section (color of the washi paper), so if the cut section is exposed on the surface of the woven fabric, "white blur" ( (The phenomenon that the surface of the fabric looks whitish)
The flat foil yarn for a drawing foil according to the present invention using a film has a transparent cut surface, and therefore does not cause “white blur”.

Therefore, it can be said that the industrial applicability of the present invention is very large.
