Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to, for example, foil yarns for weaving patterns;
This invention relates to a method for producing cut foil with three-dimensional patterns suitable as foil thread for embroidery and handicrafts.

Conventional technology and its problems Traditionally, the manufacturing method for three-dimensional patterned cut foil was to apply adhesive to the surface of a base sheet in a pattern, then apply color or metallic luster to it, or layer gold or silver foil on it. A method to obtain cut foil by slitting the fabric, a method to obtain cut foil by slitting the base sheet with a three-dimensional pattern applied to the surface of the base sheet using the applique technique, and a method to obtain cut foil by pushing up the cut foil from the back as a result of weaving. A method to obtain cut foil by smoothing the paper or resin into a pattern and slitting the original cut foil attached to the back side of the base sheet, and a method to obtain cut foil by slitting the original cut foil that has been given a three-dimensional pattern by embossing. It has been known. However, cutting foil using these conventional methods is
The following problem arose because the three-dimensional pattern was present at the stage of cutting foil.

Kirihaku can be roughly divided into so-called hikihaku and hakuhito, which are used for picture sutras and the like. Hikihaku is obtained by stacking several sheets of cut foil, which are made into relatively small panels with a fixed size that corresponds to the length, that is, slightly larger than the width of the fabric, and cutting them with a guillotine cutter. is obtained by cutting a long sheet of cut foil using a cutter with many parallel blades called a micro slitter. No matter which method of cutting foil is made using the above conventional methods, if it is the former foil thread or hikihaku, if the degree of unevenness due to the three-dimensional pattern is large, it will not be possible to cut it with a guillotine cutter unless the number of stacked sheets of cut foil material is reduced, resulting in poor workability. If the three-dimensional pattern of the stacked cut foil material is shifted, uneven cutting will occur. In the case of the latter foil yarn, if the degree of unevenness due to the three-dimensional pattern is large,
Since the blades of the micro slitter are quickly worn out when cutting the original paper, it is necessary to reduce the degree of unevenness of the three-dimensional pattern. If the degree of unevenness is small, the decorative value of the three-dimensional pattern is low.

Furthermore, in order to make the pattern three-dimensional, the traditional method of cutting foil involves applying adhesive or resin as a means of imparting a three-dimensional pattern to the outer surface, the front or back surface of the original cutting foil, which creates a three-dimensional pattern. If the means was modified to a foamed resin in order to improve the quality, the three-dimensional pattern would not be able to withstand the friction during slitting the cut foil material or weaving the cut foil, and would easily be damaged. Even if it were possible to make slits or weave, the three-dimensional pattern would peel off or otherwise be damaged due to the tugging and friction during use of the fabric. In any case, it is far from practical in terms of quality.

An object of the present invention is to provide a method for manufacturing cut foil with a three-dimensional pattern that eliminates the problems caused by the above-mentioned prior art.

A further object of the present invention is to provide a method for producing cut foil with a three-dimensional pattern that has a good texture in the three-dimensional pattern portion.

Means for Solving the Problems The above objects of the present invention are achieved by the following method.

Creating a laminate of multiple layers of base sheets having a pattern formed by applying a heat-foamable resin coating material in the intermediate layer, and decorating the front and back surfaces or the front surface of the laminate,
The cut foil obtained by slitting this is heated, thereby foaming the heat-foamable resin in the cut foil into three-dimensional foam, and expanding the cut foil with the three-dimensional foaming of the resin to express a three-dimensional pattern on the outer surface. A manufacturing method for cutting foil with three-dimensional patterns.

In this specification, "decoration" in relation to the present invention refers to any pattern, color, or gloss that is applied to the sheet surface of the base sheet laminate, including those described in the claims section. It means "decoration."

As the decoration, for example, coloring with a coating material such as lacquer or resin, a pattern with metal foil or metal powder, a multicolor pattern or a pictorial pattern by printing or sealing, or a transfer method using stamping foil, etc. can be advantageously applied. These patterns and colors do not prevent the application of two or more sheets to a laminate of base sheets.

In the present invention, base sheets include Japanese paper, plastic film, cloth coated with resin or entirely or impregnated with resin, plastic film laminated on Japanese paper, cloth and Japanese paper laminated, etc. or a laminate of two or more thereof, or a sheet-like product containing the sheet as a component can be advantageously used. Any of these base sheets may be laminated together to form a base sheet laminate having two or more layers.

In the present invention, the decoration applied to the base sheet laminate may be in the same position and in the same pattern as the pattern of the heat-foamable resin interposed in the intermediate layer of the base sheet laminate as the cut foil original. preferable. According to this, in the fabric or handicraft decorated with the cut foil of the present invention, only the decorative area on the surface of the cut foil stands out on the fabric or handicraft, and the decoration with the three-dimensional pattern can be effectively expressed.

In the present invention, if necessary, a very thin film as a protective layer may be attached over the decoration of the base sheet laminate.

Effects As described above, in the three-dimensional patterned cut foil according to the present invention, the pattern is not yet three-dimensional at the stage of the cut foil original fabric. Therefore, according to the present invention, the conventional troubles during slitting of cut foil originals are eliminated, and the problems associated therewith are eliminated.

In the present invention, the foamed three-dimensional resin as a means for expressing a three-dimensional pattern is present in the intermediate layer of the base sheet laminate, in other words, in the inner layer of the cut foil, so it has high resistance to friction and sticking, and can be easily handled. It won't be damaged. Therefore, according to the present invention, by foaming the resin that makes the pattern three-dimensional and making it a sponge, the feel of the cut foil in the three-dimensional pattern can be improved for a purpose.

Furthermore, in order to create a three-dimensional pattern in the present invention, the resin is foamed in the inner layer of the cut foil to make it three-dimensional.The reason why the resin is foamed to three-dimensionalize the cut foil is to swell and the three-dimensional pattern appears on the outer surface. It is said that it will be done,
A three-dimensional pattern with raised vines and a rounded shape can be obtained from the inside, and this contributes to improving the appearance of the cut foil in the three-dimensional pattern area.

In the present invention, before foaming the resin, the original cut foil is slit to make the cut foil, so the resin is foamed in the cut foil, and therefore the resin is applied to the base sheet laminate, that is, the intermediate layer of the original cut foil. Regardless of whether it is foaming or not, the generated gas is released from the slit end face of the cut foil without being confined inside.
Ensures good sponging of the resin.

Effects of the Invention As described above, according to the present invention, it is possible to provide a method for producing cut foil with a three-dimensional pattern that eliminates the problems caused by the prior art described above, and to obtain a cut foil with a three-dimensional pattern that has a good texture in the three-dimensional pattern portion.

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

Japanese paper, plastic film, cloth (for example, artificial fiber cloth such as rayon, synthetic fiber cloth such as nylon, Tetron, etc.) coated with a resin, preferably a highly flexible resin, or the whole or at least the surface layer It consists of a single material such as a material impregnated with Japanese paper, a plastic film pasted on Japanese paper, a material made by pasting cloth and Japanese paper, or a laminate of two or more of these materials. Two or more base sheets 1a made up of sheets including the above are laminated with an arbitrary pattern 2 formed by coating a heat-foamable resin coating material interposed in the intermediate layer,
A laminate 1 is made. In addition to the above, the base sheet 1a includes a plastic film 11, a monochrome or multicolor color layer 12, a metal layer 13, and a protective coat layer 14.
A layer in which a plastic film 11, a monochromatic or multicolored color layer 12, a metal layer 13, a protective coating layer 14 and a Japanese paper 15 are layered in sequence (see FIG. 8) can also be advantageously used. can. The base sheet of the modified example has the protective coat layer 14
Or paste two sheets with the Japanese paper 15 side inside,
It is preferable to use the laminate 1. The metal layer 13 gives the cut foil a metallic lustrous appearance.

The pattern 2 may be formed by applying a heat-foamable resin coating material to the base sheet 1a by an appropriate method such as a printing roll or a screen method. The pattern 2 may be a sand pattern with different coating thicknesses or sizes, or a striped pattern with several different coating thicknesses.

The surface or front and back surfaces of the laminate 1 are colored with a coating material such as lacquer or resin, gloss or pattern is formed by metal vapor deposition, metal foil or metal powder, or multicolor is applied by printing or sealing or by a transfer method using stamping foil. Decoration 3 such as a pattern or a painting pattern is applied.
The laminate 1 with the decoration 3 applied to the surface is the first and third layer.
The figure shows the 2nd, 4th, 5th, and 6th ones applied on both the front and back sides.
Shown in the figure. The decoration 3 may be a so-called solid decoration as shown in FIGS. 1, 2, and 5, but the decoration 3 may be a pattern 2 of the heat-foamable resin coating material of the intermediate layer of the base sheet laminate 1.
It is better to use the same position and pattern (Figures 3, 4, and 6). If necessary, a very thin (generally about 2 to 6 microns) plastic film 4 made of polyester or the like is pasted on the decoration 3 as a protective layer to the cut foil material A obtained in this way, and then slit. to obtain cut foil. When the decoration 3 is made of metal, the cut foil looks like metallic luster. In addition,
In Figures 1 to 6, the pattern 2 and the pattern-shaped decoration 3 are exaggerated to make it easier to understand, and it goes without saying that in reality, the blanks on the left and right sides of the pattern and decoration do not exist on the cut foil original fabric A. be.

The above-mentioned cut foil is heated to foam the pattern 2 of the heat-foamable resin coating material, thereby expanding the cut foil and making a three-dimensional pattern appear on the outer surface.
