[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermal transfer type applique that can be easily manufactured and can surely perform transfer at a desired position, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
Next, the short fibers 22 are densely flockingly attached to the temporary adhesive layer 21 to form a flocking layer 23, and a pattern-like pattern adhesive layer 24 is provided on the flocking layer 23 with a strong adhesive. A structure in which a hot melt resin layer 25 is fixed on a pattern-shaped pattern adhesive layer 24 is known (see JP-B-53-35619).

As shown in FIGS. 19 to 24, an adhesive layer 32 having a desired pattern is provided on a peelable base material 31 by a thermal transfer flocking applique method, and short fibers 3 are formed on the adhesive layer 32.
3 to produce a flocking sheet A, and a separate transfer substrate 3
4, a laminated sheet B is prepared by laminating a film layer 35 made of an adhesive or a hot-melt resin having a low adhesive force. Then, the laminated sheet B is placed on the film layer 35 of the laminated sheet B to form the short fibers 33 of the flocking sheet A The flocking sheet A is superimposed so that the short fibers 33 are temporarily attached to the film layer 35, and then the peelable base material 31 is peeled off from the adhesive layer 32, and the exposed surface of the adhesive layer 32 is powdered. The transfer sheet C is manufactured by fixing the hot melt resin 36, and the transfer sheet C is placed such that the hot melt resin 36 is in contact with a desired surface of the transfer object 37, and heated and pressed to transfer the hot melt resin 36. A method in which the transfer base material 34 is peeled off by fusing it to an object 37 is known (see Japanese Patent Publication No. 2-24239).

[0004]

The heat reversible type flocking transfer cloth shown in FIG. 18 is to be reversely transferred by heat, and thus the short fibers temporarily attached to the peeling base material 20 via the temporary adhesive layer 21. The length of the short fibers 22 cannot be increased, and the lengths of the short fibers 22 must be the same, and the flocked layer 23 cannot be changed in irregularities or the like. Disadvantages.

The thermal transfer flocking applique method shown in FIGS. 19 to 24 requires a wasteful process for removing the powdery hot melt resin 36 attached to the short fibers 33. If the hot melt resin 36 If any of the short fibers are left in the film 33, the short fibers may not be transferred three-dimensionally, which may deteriorate the feeling of the short fibers. The hot-melt resin adheres to the adhesive layer 32 by leaving the hot-melt resin adhered thereon, thereby deteriorating the aesthetic appearance. A means for adhering the film 36 is required, and the short fibers 33 temporarily attached to the film layer 5 may be displaced.

The present invention has solved the above-mentioned problems, and can transfer a mark having a desired shape and color to a desired position accurately and promptly. A beautiful pattern can be obtained without sticking, and a complicated pattern can be processed without any problems. The jumping pattern separated by the pattern can be transferred as it is in the pattern configuration, and the pattern requires processing material. It is an object of the present invention to provide a heat transfer type applique that is convenient to use and easy to manufacture, for example, only the pattern portion has no loss unlike the prior art, and a method of manufacturing the same.

The present invention is constructed as described above, and provides an adhesive having strong adhesive force and elasticity to a release substrate 1 such as paper or synthetic resin film subjected to release processing. Graphic heat-sensitive adhesive layer 5 mixed with hot melt adhesive
And a short fiber 3 of rayon, nylon, acrylic, polyester, or the like is formed on the pattern-shaped heat-sensitive adhesive layer 5, and a masking pressure-sensitive adhesive tape 6 that has no tackiness when the temperature is increased by heating. When the thermal transfer type applique 10 is formed by being attached to the upper end surface portion 7 of the flocked layer 4 having the design pattern, the releasable base material 1 is transferred to the member to be transferred 12 as shown in FIGS. The pattern-shaped heat-sensitive adhesive layer 5 was peeled off, and then the pattern-shaped heat-sensitive adhesive layer 5 was applied to the work surface 14 of the member to be transferred 12 and contained in the pattern-shaped heat-sensitive adhesive layer 5 with a heater such as an iron. When heated at a temperature at which the hot-melt adhesive melts (about 120 ° C.), the melted hot-melt adhesive flows into the tissue of the member to be transferred 12, while the masking adhesive tape 6 is heated when the temperature rises (about 120 ° C.). C 8 and 17, the adhesive tape for masking 6 can be easily peeled off and removed as shown in FIGS. 8 and 17, and then cooled and the hot-melt adhesive that has flowed in becomes strongly adhered. It is.

Thus, a beautiful pattern is formed on the member to be transferred 12.

The pattern 13 having irregularities can be obtained by changing the length of the short fibers 3 forming the flocking layer 4.

A coloring agent such as a pigment or a dye is applied to a part or the entire surface of the flocked layer 4 of the design pattern to form the flocked layer 9 having colored fibers, thereby enabling a desired pattern to be formed simply, quickly and reliably. What can be done.

At the time of storage, a masking adhesive tape 6, which is completely non-adhesive when the temperature rises due to heating, is attached to the upper end surface 7 of the flocking layer 4 or the pattern flocking layer 9, and the flocking layer 4 is formed by the release substrate 1. A flocked layer 4 which is pinched and does not deteriorate for a long period of time can be obtained, and a beautiful pattern 13 can be surely formed at the time of transfer.

Further, the transfer to the transfer-receiving member having elasticity is easy, and when the transfer-receiving member expands and contracts, the gap between the short fibers 3 is appropriately adjusted by the pattern-shaped heat-sensitive adhesive layer 5 so that the short fibers are adjusted. 3 can be prevented, and a beautiful three-dimensional pattern or pattern such as a character can be obtained.

Conventionally, during the processing step, the excess powder or pellet-like hot-melt adhesive to be sprayed on a flocked portion other than the pattern required by the powder or pellet-like hot-melt adhesive is removed and cleaned. Although it is necessary to do so, it is not necessary to perform complicated means as in the conventional process when forming the pattern-shaped heat-sensitive adhesive layer 5, and the pattern-shaped heat-sensitive adhesive layer 5 is formed by a simple process.

Further, it has a very simple structure, is suitable for mass production, can be provided at a low cost, and has many industrial effects, such as being capable of being transferred by a woman using a simple operation using an iron. is there.
