[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patch and a method for manufacturing the patch, and more particularly to a patch in which a film having various patterns is adhered to a cloth in a state where a predetermined portion of the pattern is raised and a method for manufacturing the patch.

2. Description of the Related Art In general, it is widely used to attach a patterned emblem to clothes, a hat, a bag, or the like for the purpose of showing a person's identity or enjoying fashion, and furthermore, a three-dimensional pattern having a bulging pattern. Some emblems are also used.

It has been demanded to provide a patch in which the swelling does not change even after many years of use and dry cleaning, and the original three-dimensional effect is maintained forever. It responds.

[0004]

2. Description of the Related Art FIG. 4 is an explanatory view showing a conventional patch in which a pattern portion is inflated, 11 is a cloth such as felt, 12 is a film such as urethane or vinyl chloride on which various patterns are printed, 13 Shows sponges for giving a bulge to any part of this pattern.

As described above, the sponge 13 is provided in the space between the cloth 11 such as felt and the pattern of the film 12.
By adding as necessary, the patch has a three-dimensional effect.

FIG. 5 shows a procedure for manufacturing an emblem having a three-dimensional appearance in which the predetermined pattern portion is swollen. That is, (1) the cloth 11 such as felt is placed on the workbench. (2) A first adhesive film having a property of melting at a predetermined temperature and performing an adhesive action is laminated on the cloth 11. (3) A sponge 13 for ensuring a final three-dimensional effect is placed on the first adhesive film. (4) The second adhesive film having the above properties is placed on the sponge 13. (5) A film 12 of urethane, vinyl chloride, or the like on which various patterns are printed is laminated on the second adhesive film. (6) The above-mentioned five-layer structure is heat-pressed from the side of the film 12 with a concave mold corresponding to the three-dimensional shape of a predetermined pattern portion. By each step, a predetermined bulge is given to the pattern part of the patch.

That is, the sponge 13 in the region pressed by the portion other than the concave portion of the concave mold is in the squashed state, while the sponge 13 in the region corresponding to the recessed portion is not in the squashed state.

Then, the first and second adhesive films sandwiched between the cloth 11 and the sponge 13 and between the film 12 and the sponge 13 are removed by the pressure-bonding heat treatment in the previous step (6). After melting, the fabric 11, the sponge 13, and the film 12 are integrated.

In this step (6), the wafer is heated to, for example, about 80 C using a concave mold having a built-in heater.
Further, a high frequency electric field (magnetic field) is also added to shorten the working time. Also, film 1

[0011]

As described above, in the conventional patch, the pattern portion is bulged by interposing the sponge between the cloth and the patterned film. Sponge, which is a resin, is naturally prone to deterioration and softens when subjected to thermocompression bonding.
Since it has a property of easily melting, there is a problem that when the sponge portion is pressed from above or ironed, the sponge is in a compressed state and the original bulge disappears. In addition, resin
Glues the inflated pattern part to the fabric by interposing
Is provided separately from the resin,
There was a problem that the structure of the patch became complicated.

Therefore, in the present invention, a patch is used by using a thermosetting resin, such as a silicone resin or a urethane resin, which is less likely to be naturally deteriorated and does not soften even when subjected to thermocompression bonding, instead of a conventional sponge. The swelling of the pattern portion is maintained as it was at the time of manufacture , and the thermosetting resin itself was used for fabric and pattern lining.
By adhering it to the film,
No special sheet is required for the bonding of the resin
The purpose is to simplify the patch structure.

[0013] Further, at the time of the production, these thermosetting resins are used in a grease state, and the cloth and the patterned film are integrated by utilizing an adhesive action when the thermosetting resins are cured. The purpose is to simplify the patch manufacturing process.

[0014]

[Means for Solving the Problems] In order to solve this problem
In the present invention, the raised portion of the film pattern and
The space between the dough and the fabric is made of thermosetting resin, and this heat
The curable resin itself forms the space and other
Adhere to the fabric and film between the film and the fabric
It has such an emblem structure.

Further, at the time of its manufacture, between the back surface side of the patterned film and the cloth in a state where a predetermined pattern portion is raised, and between the concave mold and the cloth corresponding to the three-dimensional shape of this pattern portion. A thermosetting resin is interposed in the form of a grease between them, and then this portion is cured by thermocompression bonding.

[0016]

Therefore, the swelled pattern portion of the present invention maintains the original three-dimensional shape forever because the thermosetting resin thereunder does not deteriorate naturally. Even when heated, the underlying base portion (thermosetting resin) does not soften, so that the three-dimensional appearance of the pattern is maintained in the state at the time of creation.

Further, in the course of the manufacturing process, a thermosetting resin such as a silicone resin is greased, poured into a predetermined portion, and then cured while heating.
By this curing of the thermosetting resin, the space between the patterned film and the cloth is bonded.

[0018]

Embodiments of the present invention will be described with reference to FIGS. FIG. 1 is an explanatory view showing an emblem in which the pattern portion of the present invention is inflated, 1 is a cloth such as felt, 2 is a film such as urethane or vinyl chloride on which various patterns are printed, 3 is an arbitrary pattern Indicates a thermosetting resin such as a silicone resin or a urethane resin for giving swelling to the portion.

Here, the difference from the conventional emblem shown in FIG. 4 is a portion of a thermosetting resin 3 such as a silicone resin or a urethane resin, and other materials 1 and a film 2 are the same as the conventional one. .

Further, the thermosetting resin 3 is also interposed between the non-bulging portion (the portion without the pattern) of the film 2 and the cloth, and as will be described later, the thermosetting resin 3 adheres to both of them. Is one.

FIGS. 2 and 3 are explanatory views showing a method of bonding a film 2 on which various patterns are printed to the fabric 1 according to the present invention in a state where any predetermined portion of the patterns is raised.

That is, in the manufacturing method shown in FIG. 2, the flat film 2 is sandwiched and pressed between the respective molds having irregularities corresponding to the three-dimensional shape of the predetermined portion so that the predetermined portion is lifted and the convex portion is raised. After removing the mold, a grease-like thermosetting resin 3 is flowed on the back side of the film 2 having a predetermined portion depressed, and the cloth 1 is applied to the surface of the grease-like thermosetting resin 3 and heated. The procedure is such that the thermosetting resin is cured by pressing with a flat plate, and the fabric 1 and the film 2 are integrated by the adhesive action in this step.

The manufacturing method shown in FIG. 3 is as follows: 'The grease-like thermosetting resin 3 is poured into a concave mold corresponding to the three-dimensional shape of the predetermined portion, and the exposed surface is flattened. The thermosetting resin is cured by applying the cloth 1 and then heating. 'The integrated thermosetting resin 3 and the cloth 1 are taken out from the concave mold, and' the three-dimensional surface of the thermosetting resin is Apply adhesive film,
Furthermore, the film 2 is applied so that its pattern conforms to the surface shape of the three-dimensional surface, and a procedure is adopted in which the pattern is heat-pressed with a concave mold corresponding to the three-dimensional shape of the predetermined portion. By the action of the adhesive film in this step, the thermosetting resin which has already been cured and the film are integrated. When a vinyl chloride film is used as the film 2, the adhesive film in step 'is unnecessary as mentioned above.

As described above, in any of the manufacturing methods, since a silicone resin or the like for expanding a predetermined pattern portion is used as a kind of adhesive, the number of steps can be reduced and the use of an adhesive film is reduced. Is what you can do.

In the case of heat treatment, for example, 100
Heating may be performed at a temperature of {120} for about 1.5 minutes. If high-frequency heating is used, the time required for curing the thermosetting resin can be shortened and the working efficiency can be increased. Further, it goes without saying that the heater heating and the high frequency heating may be used together.

[0026]

As described above, according to the present invention, the pattern expansion
A laminator portion, less deterioration, the form by the heated thermosetting resin not to soften be (such as silicone resin)
Since the forms, it is possible to hold the patterned portions forever remain manufacture original three-dimensional shape. Furthermore, this
Since the thermosetting resin of also acts as an adhesive, the pattern
Adhere the resin to be put into the bulge part of the fabric to the fabric or pattern film
A special adhesive layer is not required to make the structure of the patch
Can be simplified.

In the manufacture of an emblem, since the silicone resin or the like functions as an adhesive, the manufacturing process can be simplified and the use of an adhesive film can be reduced.
