Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing patches, emblems and the like, and more particularly to a patch which can form a fine and vivid three-dimensional pattern without losing its shape and which is excellent in its production efficiency. It relates to a manufacturing method.

[0002]

2. Description of the Related Art A conventional patch is generally manufactured by embroidering a cloth on a cloth, and a conventional emblem is usually manufactured by hand embroidering on a suede cloth or cloth. Target.

[0003]

However, such a manufacturing method has a problem that the production efficiency is very poor. Furthermore, the emblem manufactured in this way is
There is also a problem that it cannot be sewn onto clothing because it cannot be dry cleaned.

On the other hand, artificial leather sewn for clothing or the like, for example, has a mark or a character formed on a die attached to the upper surface plate of a press machine, and is heated into the artificial leather by using heater heat. Marks etc. are branded. Alternatively, for example, the surface of the artificial leather is appropriately printed in advance, and the printed portion is processed to be concave or convex to form a label mark or the like.

However, such a product has a problem that it cannot be used as an insignia because it has no metallic feeling on the surface because it is made of only artificial leather. There is also an artificial leather with aluminum foil bonded to the surface, but if an uneven pattern is formed on such an object, the artificial leather will warp when the uneven pattern is formed, and therefore, However, there is a problem in that the manufacturing process of (3) is difficult.

The present invention has been made in view of this problem and is a manufacturing method excellent in production efficiency.
An object of the present invention is to provide a method for manufacturing a patch or the like that can form a fine and vivid three-dimensional pattern that does not lose its shape even when it is cleaned or ironed.

[0007]

In order to achieve the above-mentioned object, the manufacturing method according to claim 1 has a three-dimensional pattern including a fine pattern on the surface, a simple groove, and a concave groove in which the fine pattern is engraved. Using a concave mold that forms a groove and a concave mold that is formed corresponding to the fine groove engraved with the fine pattern, and only the concave groove is projected by inverting the concave and convex, a patch or the like is formed by welding molding processing. It is characterized by manufacturing.

As described above, according to the manufacturing method of the first aspect, the welding molding process is performed while pressing the patch material or the like with the concave groove having the fine pattern and the protrusion corresponding to the concave groove. It is possible to vividly form a fine three-dimensional pattern by a single process. In addition, since the back surface of the raised portion with a fine pattern is recessed by the above-mentioned convex protrusion, the fine pattern becomes more vivid as much as there is no unnecessary bulge in the finished product, and moreover, by an iron etc. It is also possible to prevent the three-dimensional pattern from collapsing.

In the manufacturing method of claim 2, the surface sheet and the artificial leather with the adhesive sheet interposed are used.
Also in this case, a fine three-dimensional pattern can be vividly formed by a single process. In addition, the strength of the three-dimensional pattern is increased by the amount that the artificial leather is bonded to the surface sheet.

In the manufacturing method of the third aspect, since the surface sheet such as a patch is composed of three layers and is formed by the aluminum foil and the upper and lower polyurethane layers sandwiching the aluminum foil, a gloss with a metallic feeling is obtained. A rich three-dimensional pattern can be formed.

In the manufacturing method of claim 5, the adhesive sheet is placed on the special fiber layer of the artificial leather, the surface sheet is further placed thereon, and these are weld-molded by the convex and concave molds. Since it is processed, the back surface of the raised part of the three-dimensional pattern is a polyurethane layer, and the strength of the recessed part is excellent, so it is possible to more reliably prevent the three-dimensional pattern from being destroyed by an iron or the like. Further, since the special fiber layer and the surface sheet are adhered to each other, air can be easily released during the welding molding process, and there is no fear that the sealing air will form an unnecessary bulge, and a fine three-dimensional pattern is formed more vividly. The special fiber layer is not particularly limited, but for example, special Tetron fiber is applicable.

In the manufacturing method of the sixth aspect, the unnecessary portion is removed after the welding and molding process, the unnecessary part is placed on the fiber material, and the edging process is performed with the embroidery thread. Warmth increases further.

[0013]

The present invention will be described in more detail based on the following examples. FIG. 1 is a view for explaining a method of manufacturing a patch or the like which is an embodiment of the present invention, in which a concave mold 1 and a convex mold 2 attached to upper and lower surface plates of a high frequency welder machine, and concave and convex molds 1 and 2 3 shows an insignia material 3 to be fusion-molded by.

The concave mold 1 is attached to the upper surface plate of a high-frequency welder machine, and includes a surface portion 1a having a fine pattern, a simple concave groove 1b, and a concave groove 1c having a fine pattern. Has been formed. The concave groove 1b is a groove for forming a character as a whole or for forming a simple pattern (mark or the like) formed by a protrusion. On the other hand, the concave groove 1c is a groove for forming a three-dimensional pattern including a fine pattern on the surface of the protrusion, not a simple pattern formed by the protrusion. For example, referring to the insignia shown in FIG. 3, the central leaf portion 11 is required to raise the entire leaf and to form a vein pattern on the raised leaf, so that the leaf portion 11 is engraved in the groove 1c. Need to It should be noted that a fine concavo-convex pattern (pattern pattern) is formed in other portions in FIG. 3, and this concavo-convex pattern is stamped on the surface portion 1a.

The convex mold 2 is mounted on the lower surface plate of the high-frequency welder machine, and only the above-mentioned concave groove 1c is inverted to form the convex portion 2c.

FIG. 4 shows the structure of the insignia material 3 in more detail. The base material 4, the surface sheet 5, and
An adhesive sheet 6 for adhering the surface sheet 5 to the base cloth 4 is illustrated. The base cloth 4 is an artificial leather composed of two layers of special polyurethane 7 and special Tetron fiber 8, and its thickness is, for example, about 1.5 mm. The topsheet 5 is a three-layer laminated urethane sheet in which an aluminum foil 9 is sandwiched between upper and lower polyurethane sheets 10, 10 and has a thickness of, for example, about 0.15 mm. The surface sheet 5 has a silver color tone and appropriate characters and patterns are urethane-based ink (paint).
It is printed with. Since the urethane-based ink is used in this way, it is strong against washing such as perchlorethylene and petroleum dry cleaning, and is also resistant to fading by outdoor ultraviolet rays. The adhesive sheet 6
Is formed of a hot melt adhesive.

Next, a method of manufacturing the insignia having the pattern as shown in FIG. 3 using the concave mold 1 and the convex mold 2 shown in FIG. 1 will be described. Recessed type 1 on the surface plate of the high-frequency welder
The convex mold 2 is attached to the mounting position of the lower surface plate corresponding to the mounting position of the concave mold 1, and the concave mold 1 is warmed by the heat of the heater. Then, the artificial leather 4 is placed on the convex mold 2. In the case of this embodiment, the artificial leather 4 is placed with the special polyurethane 7 on the bottom and the special Tetron fiber 8 on the top.

After that, the adhesive sheet 6 is placed on the special Tetron fiber 8 of the artificial leather 4, and the surface sheet 5 on which the pattern is printed is further placed thereon. And base fabric 4
And an insignia material 3 consisting of an adhesive sheet 6 and a surface sheet 5,
A high-frequency energy is applied between the concave-convex molds 1 and 2 sandwiched between the convex mold 2 and the concave mold 1, and a fusion molding process (press) is performed with the high-frequency energy and the heat of the heater to form a fine three-dimensional pattern.

As described above, the convex mold 2 is formed in a convex shape only in the raised portion (for example, the leaf portion 11 in FIG. 3) containing the fine pattern, while the concave mold 1 has the entire surface of the polyurethane sheet 10. Since the fine three-dimensional pattern is formed, the three-dimensional pattern having a cross section as shown in FIG. 2 is formed by the welding molding process. That is, concave type 1
Characters and the like are formed as simple protrusions on the concave groove 1b of the above, but since the concave groove 1c forms a bright fine pattern on the protrusion surface of the insignia material 3 by interaction with the protrusion 2c. is there. As described above, since the three-dimensional pattern having a vivid fine pattern is completed in a single process, the production efficiency is very high.

Since the convex mold 2 is brought into contact with the portion of the special polyurethane 7 of the artificial leather 4, after the fusion molding process,
The contact point of the special polyurethane 7 with the convex mold 2 is fixed in a depressed state (see FIG. 2). The special polyurethane layer 7 fixed in a partially recessed state is the surface sheet 5
It will act as a reinforcing layer wall for the three-dimensional pattern, and it will not lose its shape even when it is ironed.

Further, since the urethane resin sheet sandwiching the aluminum foil appears on the surface of the insignia, it is possible to provide a product having an appearance similar to that of a metal having a high gloss. Furthermore,
Since the special tetron fiber layer 8 of the artificial leather 4 and the polyurethane layer 10 of the surface sheet 5 are adhered to each other, the product does not warp due to the welding process, and the air can be easily released from the adhesion part. That is, when the special polyurethane layer 7 of the artificial leather 4 and the polyurethane layer 10 of the surface sheet 5 are fusion-molded, the product may warp or air may be sealed in the adhesive portion. According to the manufacturing method of the example, not only the product does not warp, but also the sealed air does not adversely affect the fine pattern of the surface sheet and does not damage the product value (aesthetics), and the fine uneven pattern is formed vividly. It is.

After the surface sheet 5 and the artificial leather 4 have been weld-molded as described above, unnecessary portions are removed using a punching die. Then, the punched product is overlaid on the fiber material and the periphery of the product is edging (locked) by a sewing machine. As described above, since the product does not warp due to the welding molding process, there is no difficulty in this overedging process. Further, since the aluminum foil 9 of the topsheet 5 is sandwiched by the polyurethane sheets 10, even if a hole is made with a needle during sewing, there is no risk of tearing from the hole portion and there is no difficulty in mounting work. Here, the fibrous material is not particularly limited, but for example, a black embroidery nonwoven fabric having a thickness of about 0.4 mm is preferable. Further, for the overedging processing, for example, a black rayon embroidery thread may be used.

By the above-mentioned edging processing, the artificial leather 4
Since the strength of the bonding portion between the surface sheet 5 and the
There is no risk of the top sheet peeling. Further, since embroidery is applied around the insignia (emblem, emblem, etc.), the warmth and luxury of the product are emphasized. Finally, the insignia (emblem, emblem, etc.) is completed by removing unnecessary parts of the fiber material.

The embodiment of the present invention has been described above.
The present invention can be further modified appropriately. For example, in the above embodiment, the edging process is performed after the welding molding process, but the invention is not limited to this. For example, a polyurethane resin may be put in the concave portion of the special polyurethane layer 7 of the artificial leather 4. You can When the inserted polyurethane resin hardens, the concave portion of the special polyurethane layer 7 is filled so that the back surface of the artificial leather 4 becomes a flat surface, and the strength of the patch increases accordingly, and the shape is more securely deformed by ironing. Can be prevented.

[0025]

As described above, according to the manufacturing method of the present invention, the recessed groove having the fine pattern and the projection corresponding to the recessed groove are used for the welding molding process while pressing the patch material or the like. Therefore, it is possible to vividly form a fine three-dimensional pattern in a single step, which is excellent in production efficiency. In addition, since the back surface of the raised portion of the formed three-dimensional pattern is recessed, it is possible to prevent the three-dimensional pattern from collapsing due to an iron or the like as much as there is no unnecessary bulge.

In this manufacturing method, when the surface sheet and the artificial leather with the adhesive sheet interposed are used, the strength of the three-dimensional pattern is further increased by the amount that the artificial leather is bonded to the surface sheet. Further, when the surface sheet is formed of an aluminum foil and upper and lower polyurethane sheets that sandwich the aluminum foil, a three-dimensional pattern with a metallic feel and rich gloss can be formed. Furthermore, since the polyurethane sheet is strong against washing such as dry cleaning,
The appearance of the surface sheet can be maintained for a long period of time.

When the adhesive sheet is placed on the special fiber layer of the artificial leather, and the surface sheet is placed on the adhesive sheet, and these are subjected to the welding molding processing by the convex and concave molds, a three-dimensional pattern is formed. The back surface of the raised part becomes a polyurethane layer,
Since the recessed part has excellent strength, it is possible to more reliably prevent the three-dimensional pattern from collapsing due to ironing. In addition, since the special fiber layer and the surface sheet are adhered to each other, air is easily released during the welding molding process, and there is no fear that the sealing air will form unnecessary bulges. In other words, the fine concavo-convex pattern is formed more vividly, and the commercial value is increased.

Further, when the unnecessary portion is removed after the welding molding process, and this is placed on the fibrous material and edging with the embroidery thread, the high quality and warmth of the finished product are further emphasized. be able to.
