Description

[Detailed description of the invention] The present invention relates to a method for manufacturing double-sided pattern warp foil yarn.

In general, it is considered best to weave patterned foil threads into textiles to create painterly-like subtle color shading.

Conventionally, foil threads with the same pattern on the front and back sides have been proposed, but a warp foil system with the same pattern on the front and back sides with an excellent texture has not yet been developed.

The inventor of the present invention focused on the development of a warp foil yarn with the same pattern on the front and back sides, and conducted repeated research, but in the process, he encountered a major problem. In other words, in order to obtain the desired warp foil yarn with the same pattern on both the front and back sides, the pattern must be applied at the correct position on the front and back sides, and this can be done over a warp yarn length of at least 50 meters. A new challenge arose: a solution to ensure concise and accurate processing of the material sheets.

Accordingly, an object of the present invention is to provide a method for producing double-sided patterned warp foil yarn, which allows the same pattern with excellent texture to be simply and accurately applied to both the front and back surfaces.

The method for manufacturing the double-sided patterned warp foil yarn of the present invention involves adding a base paper for gold or silver flat foil (hereinafter referred to as base paper for gold (or silver) foil, which is referred to by those skilled in the art as base paper for gold (or silver) foil), which is narrower in width than the transparent base film, on one side of the transparent base film. , gold and silver leaf base paper), which is obtained by dividing a material with a length equivalent to twice the length of the target warp leaf thread into two halves, or twice the length of the fabric to be woven. A material with a width corresponding to the width of is divided into two on the left and right, one of which is pasted and laminated with a margin left on the left and right, and the two halves of the material are placed on the other side of the transparent base film. The other film is adhered and laminated with margins left and right on the left and right, and a film is further adhered and laminated on the gold and silver foil base paper that is adhered and laminated on the front and back sides of the transparent base film, and the composite laminate thus obtained is obtained. A pattern is applied to the film on the gold and silver foil base paper on one side of the body, an alignment mark is applied to the margin of the transparent base film on that side, and the above pattern is applied to the film on the gold and silver foil base paper on the other side of the composite laminate. It is characterized by applying the same pattern, aligning the pattern based on the above mark under transparent view, and then cutting the composite laminate to the required width to obtain the desired product. .

In the present invention, a composite laminate in which gold and silver foil base paper and film are laminated on the front and back sides of a base film is used as the material for the warp foil yarn. The pattern between the foil threads on the loom is based on the uneven elongation due to the uneven thickness of the material, which can solve the problem of uneven thickness, and therefore can be seen in the foil thread obtained by cutting the material consisting of a single layer. There is no deviation. Even though the composite laminate needs to have a length of at least one weaving lot length (at least 50 m using a normal loom), by laminating its constituent materials on one side, one on the front and one on the back, wrinkles do not occur. can achieve this. When attaching such a long film or gold/silver foil base paper to both the front and back sides of the base film at the same time, the front and back long films or base paper should be laminated while being held at the same tension to prevent wrinkles. It is technically extremely difficult to do this in practice, but if you do it one side at a time, you can pull the base film lightly to the extent that it does not loosen, and then attach the laminated film or base paper to it in the usual way. Tension-controlled winding allows for wrinkle-free application. Thus, according to the present invention, a long material made of a composite laminate that is free of wrinkles and has a good texture can be obtained industrially and simply.
The texture of the material is equivalent to twice the length of the target warp foil yarn, or twice the length of the fabric to be woven, to the gold and silver foil base paper that is laminated on the front and back sides of the transparent base film.
Since we apply the material obtained by dividing the material with a width equivalent to twice the width into front and back or left and right, the table,
The backs match. This is because the gold and silver foil base papers obtained in this way are products of the same lot and have substantially the same physical properties such as thickness, strength, and stiffness.

On the other hand, if the textures of the front and back sides of a composite laminate do not match, the textures of the front and back patterns will also not match, and furthermore, even if the positions of the front and back patterns are aligned, their usefulness will be extremely limited. Although it will be low,
In the present invention, as described above, a composite laminate with matching textures on the front and back sides can be obtained, and therefore, its usefulness is high.

In the present invention, if necessary, a coating layer for sealing (for example, a coating layer of lacquer or synthetic resin) or a sealing coating layer and the like are applied to the gold and silver foil base paper on the front and back sides of the long material. A protective coating layer may be formed as an overcoat, and a metal vapor deposition layer for imparting metallic luster may be formed on the front and back films, if necessary.

In the present invention, a pattern is then applied to the films on the gold and silver foil base paper on the front and back sides of the elongated material by an appropriate means, such as printing. In this case, in the present invention, there are margins on the left and right sides of the transparent base film of the material, and alignment marks are attached to these margins, so that after the pattern is applied to the front surface of the material, the pattern can be formed on the back surface. At times, while looking through the mark, it is possible to simply align the pattern necessary for applying the pattern on the back surface based on the mark.

In the present invention, gold and silver foil base paper is pasted and laminated on the front and back sides of a base film, and a film is further pasted and laminated on top of the gold and silver foil base paper on the front and back sides of the base film, and a pattern is applied on top of the gold and silver foil base paper. The double-sided patterned warp foil yarn has a fluffy and soft texture, and has excellent texture, luster, and color tone. According to the invention, therefore:
The delicate texture required for high-quality Nishijin-ori obi can be expressed in double-sided pattern warp foil yarn.

However, when gold and silver foil base paper is pasted onto a base film, wrinkles occur after pasting, and these wrinkles appear in the pattern when printed. If the wrinkles occur in different ways on the front and back sides of the paper, the patterns on the front and back sides will look different. These are phenomena discovered at the research stage related to the present invention.

In view of this problem, the inventor of the present invention made many attempts to make the wrinkles uniform between the front and back sides of the base film after pasting the gold and silver foil base paper on the front and back sides of the base film. The material obtained by dividing a gold and silver leaf base paper corresponding to By applying and laminating one side of the base film on one side of the base film and the other side of the base film on the other side of the base film,
We succeeded in making wrinkles uniform in the paper on the front and back sides of the base film. Thus, according to the present invention, a film is further adhered and laminated on top of the gold and silver foil base paper laminated on the front and back sides of the base film, and the same pattern is applied on the front and back sides.
This can be formed with the same texture on the front and back.
The present invention provides a method for producing double-sided pattern warp foil thread that has the subtle texture required for high-grade Nishijin-ori obi and can also produce the same pattern on the front and back sides.

Moreover, by laminating gold and silver foil base paper on the front and back sides of the base film and then laminating a film on top of it, the above-mentioned fluffy and soft texture based on the gold and silver foil base paper can be obtained. Since it is viewed through the film, it has a sinking feeling and depth.

In this way, the present invention guarantees to obtain a double-sided patterned warp foil yarn original fabric having the same desired pattern on both the front and back sides simply and accurately, and by cutting it, a double-sided pattern warp foil yarn can be obtained. .

Next, embodiments of the present invention will be described with reference to the drawings.

The transparent base film 1 can be made of any suitable material, such as polyester film or nylon film. The thickness of the film can vary within a wide range, but is generally preferably less than 0.01 mm. The width of the film needs to be slightly wider than the width of the fabric, and generally, for example, if the width of the fabric is 300 mm, the width of the film is 350 mm.
mm width. The length corresponds to the length of the fabric.

The gold and silver foil base paper 2 adhered and laminated on the front and back surfaces of the transparent base film 1 can be, for example, the same gold and silver foil base paper conventionally used for patterned warp foil threads or weft foil threads. The film 3 to be laminated on the gold and silver foil base paper can be made of any suitable material, for example, the same material as the transparent base film. The thickness may be appropriately selected depending on the purpose. This base paper and film have a width narrower than that of the transparent base film 1.
That is, the width corresponds to the width of the fabric.

The gold and silver foil base paper laminated on the front and back sides of the transparent base film 1 may be provided with a sealing coating layer (for example, a coating layer of lacquer or synthetic resin), or a sealing coating layer and its overcoat, if necessary. A protective coating layer is formed on the film 3, and a metal vapor deposited layer 5 for imparting metallic luster is formed on the film 3, if necessary.

The above-mentioned gold and silver leaf base paper 2 is made from the same lot and has a length equivalent to twice the length of the target warp thread or a width twice the width of the fabric to be woven, for the above-mentioned purpose. Appropriate a material with a width equivalent to
This is divided into two parts, either front and back or left and right, and the obtained result is applied. When forming the above-mentioned sealing coating layer or metal vapor deposition layer on the gold and silver foil base paper 2 or the film 3, in order to make the purpose of matching the texture of the front and back of the warp foil yarn more rationally, After formation, the material is subjected to the two-part treatment described above.

The adhesion and lamination of the gold and silver foil base paper 2 on the transparent base film 1 and the adhesion and lamination of the film 3 on the base paper 3 are performed on each of the front and back sides. This lamination may be carried out using a conventionally known adhesive and by a conventional tension-controlled winding method. During lamination, margins 7 are left on the left and right sides of the transparent base film 1.

Patterns are then applied to the films on the gold and silver foil base paper on the front and back sides of the composite laminate thus obtained. This pattern may be formed by any appropriate means, such as printing.

When forming the first pattern, a suitable positioning mark, for example, a circle mark, is placed on the margin 7 of the transparent base film 1 on that side. A pattern identical to the first pattern is formed on the opposite side. When forming this latter pattern, while looking through the alignment marks,
Based on this, alignment for forming the pattern is performed. The verification may be performed by applying, for example, a method used in multicolor printing, and an appropriate mark that matches the above-mentioned O mark, for example, a + mark, can be used as the verification mark. These marks will be matched.
