Description

[Detailed description of the invention] The present invention relates to a method for producing a warp yarn for pattern appearance.

In general, it is considered best to weave decorative flat threads to reveal patterns in order to create painterly-like subtle color shading in textiles.

Traditionally, such decorative flat threads have been obtained by using paper, plastic film, etc. as a base material, applying a desired pattern to it, and then cutting it into many narrow ribbons. There are some that are applied and some that are appropriated as sutras. In the case of wefts, the pattern originally applied to the base material is reproduced on the fabric by manually weaving decorative flat threads in a predetermined order (referred to as the "sequential technique"). In addition to being poor in quality, it requires a high degree of skill and skill, and it is not easy to align each decorative flat thread, which is required to make the pattern appear without any deviation.

On the other hand, warp yarns have an advantage in that the decorative flat threads are adjusted in diameter and automatically woven by the loom, but the adjusted decorative flat threads are often turned inside out when they are opened, making it difficult to reveal the appropriate pattern. It ends up not being done. This problem with warp can be solved by applying a transparent film to the base material of the decorative flat threads, as the pattern can be seen through the base material even if the threads are reversed. However, in this case, the pattern is indirectly revealed through the transparent base material, so there is a problem with the texture.

Furthermore, although flat yarns with patterns facing the front and back sides have already been proposed, a warp flat yarn with patterns that are the same on the front and back sides and has an excellent texture has not yet been developed.

The inventor of the present invention focused on the development of decorative warp and flat threads 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 decorative warp flat yarn with the same pattern on the front and back sides, the pattern must be applied at the correct position on the front and back sides, and this can be applied to decorative warp flat yarns that are at least 50 meters long. 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 manufacturing warp and flat threads for pattern revealing, which allows the same pattern with excellent texture to be simply and accurately applied to the front and back surfaces.

The method for manufacturing the warp flat yarn for pattern revealing of the present invention is to add a base paper for gold or silver flat foil (which is called gold (or silver) foil base paper by those skilled in the art), which is narrower in width than the transparent base film, on one side of the transparent base film. (hereinafter referred to as 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 and flat yarn into two halves, or a material 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 and right on the left, and the other half of the material is placed on the other side of the transparent base film. A film is further adhered and laminated on the base paper for the synthetic or silver foil, which is laminated on the front and back sides of the transparent base film, with margins left and right on the left and right sides, and a film is laminated on top of the base paper for the above synthetic or silver foil, and the resulting film is laminated on the front and back sides of the transparent base film. A pattern is applied to the film on the gold and silver foil base paper on one side of the composite laminate, and an alignment mark is applied to the margin of the transparent base film on that side, and the film on the gold and silver foil base paper on the other side of the composite laminate is applied. A pattern identical to the above pattern is applied to the
Based on this, the pattern is aligned, and then the composite laminate is cut to the required width to obtain the desired product.

According to 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 and flat threads for pattern revealing. Therefore, it is possible to solve the problem of partial thickness unevenness of the flat yarns on the loom, which is based on the uneven elongation caused by the uneven thickness of the flat yarns obtained by cutting a single-layer material. The pattern does not shift. The composite laminate has a length of at least one loom lot length (at least 50 m on a normal loom).
> Regardless of whether it is necessary to do so, this can be achieved without wrinkles by laminating the constituent materials on one side, one on the front and one on the back. When attaching such a long film or gold and silver foil base paper to the front and back screens 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. This is technically extremely difficult 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 roll the laminated film or base paper onto it using the usual tension-controlled winding method. It can be applied without wrinkles. 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 that the gold and silver foil base paper that is laminated on the front and back sides of the transparent base film has a width that is equivalent to twice the length of the target warp yarn or twice the width of the fabric to be woven. The front and back sides match because the material that has the shape is divided into halves on the front or left and right sides.

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.Furthermore, even if the positions of the front and back patterns shown below are aligned, their usefulness will be extremely limited. However, in the present invention, as described above, the table,
Since a composite laminate with matching back texture can be obtained, its usefulness is high.

In the present invention, the gold and silver foil base paper on the front and back sides of this long piece of wood is coated with a coating layer for sealing (for example, a coating layer of lacquer or synthetic resin) and/or for imparting gold luster, if necessary. A metal vapor-deposited layer may be applied, or a protective coating layer may be formed as an overcoat on the coating layer.

In the present invention, a pattern is then applied to the film 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 after applying the pattern to the surface of the material,
While forming the pattern on the back side, while looking through the mark,
Based on this, it is possible to simply align the pattern required for applying the pattern on the back side.

In the present invention, gold and silver foil base paper is adhered and laminated on the front and back sides of the base film, and a film is further adhered and laminated on the gold and silver foil base paper on the front and back sides of the base film, and a pattern is applied thereon, so that the obtained The pattern-revealing warp yarn has a fluffy and soft texture and is excellent in feel, luster, and color tone. Therefore, according to the present invention, the delicate texture required for high-grade Nishijin textile obi can be expressed in the warp and flat threads.

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 numerous attempts to make the wrinkles uniform on both sides after pasting gold and silver foil base paper on the front and back sides of the base film, and as a result, the length of the target warp and flat yarn was doubled. Applicable is one obtained by dividing the corresponding gold and silver leaf base paper into two halves, front and back, or one obtained by dividing a gold and silver leaf base paper with a width equivalent to twice the width of the fabric to be woven into left and right halves. By laminating one of them on one side of the base film and the other on the other side of the base film, they succeeded in making the 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 by applying the same pattern on the front and back sides, it is possible to improve the texture of the front and back. To provide a method for producing a pattern-revealing warp and flat thread that can be formed by flattening the same back and forth and exhibiting the delicate texture required for high-grade Nishijin textile obi and the same pattern on the front and back sides.

Moreover, like this, gold and silver @ on the front and back sides of the base film.
By adhering and laminating base paper and then adhering and laminating a film on top of it, the fluffy and soft texture of the gold and silver foil base paper will be exposed to the outside through the film, so the gold and silver foil base paper will The texture expressed in the warp and flat threads is deep.

In this way, the present invention can easily create the same desired pattern on the front and back screens.
It is ensured that the material for the decorative warp and flat threads is accurately applied, and by cutting it, the warp and flat threads for revealing the pattern 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 a polyester film or a nylon film.

The thickness of the film can vary within a wide range, but is generally less than 0.01 m preferred.

The width of the film needs to be slightly wider than the width of the woven fabric, and generally, for example, if the width of the woven fabric is 300 m, the width of the film is 350 m.
It is the width. The length corresponds to the length of the fabric.

The gold and silver foil base paper (2) that is laminated on the front and back sides of the transparent base film (1) can be, for example, the same gold and silver foil base paper that is conventionally used for decorative warp or weft/flat threads. . The film (3) to be laminated on the gold and silver foil base paper can be made of an appropriate 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 are transparent base film (1)
The width is narrower, that is, the width corresponds to the fabric width.

The gold and silver foil paper laminated on the front and back sides of the transparent base film (1) is coated with a coating layer (
For example, the film (3) has a metal vapor deposited layer (5) for imparting luster to the film (3).
) is formed.

The above-mentioned gold and silver leaf base paper (2) is made from products of the same lot and has a length equivalent to twice the length of the target warp yarn or twice the length of the fabric to be woven, for the purpose mentioned above. A material with a width corresponding to the width is appropriated, and the material obtained by dividing the material into front and back or left and right is applied. When forming the above-mentioned filler coating layer or metal vapor deposition layer on the gold and silver foil base paper (2) or film (3), in order to make the purpose of matching the texture of the front and back of the warp yarn more rationally, After the formation of this layer, 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 the front and back sides respectively.

This lamination may be accomplished using conventionally known adhesives and by conventional tension-controlled winding methods. During lamination, margins (7) are left on the left and right sides of the transparent base film (1).

A pattern is 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, remove the transparent film (
1) In the margin (7), place a suitable alignment mark, for example O
A mark will be attached. A pattern identical to the first pattern is formed on the opposite side. During this latter pattern formation, the alignment mark is viewed through and alignment for forming the pattern is performed based on it. For the verification, for example, a method used in multi-color printing may be applied, and as a mark for verification, an appropriate mark that corresponds to the above-mentioned Q mark, such as a cross mark, can be used. When these marks are matched, they become ■.
