[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 18, a temporary adhesive layer 21 is provided on a peeling base material 20 using a heat reversal type flock transfer material
Next, the short fibers 22 are temporarily adhered to the temporary adhesive layer 21 with a high density to form a flocked layer 23, and a pattern adhesive layer 24 having a pattern is provided on the flocked layer 23 with a strong adhesive. It is known that the hot-melt resin layer 25 is fixed on the pattern-shaped pattern adhesive layer 24 (see Japanese Patent Publication No. 53-35619).

Further, as shown in FIGS. 19 to 24, an adhesive layer 32 having a desired pattern is provided on a peelable substrate 31 by a method of thermal transfer flocking applique, and the short fibers 3 are provided on the adhesive layer 32.
3 is planted to fabricate a flocked sheet A, and a transfer base material 3 is separately prepared.
4 is provided with a laminated sheet B in which a film layer 35 made of an adhesive having a weak adhesive force or a heat-melting resin is laminated, and then the laminated sheet B is laminated on the film layer 35 of the laminated sheet B and the short fibers 33 of the flocked sheet A. So that they contact each other, the short fibers 33 are temporarily attached to the film layer 35, the peelable base material 31 is then peeled off from the adhesive layer 32, and the exposed surface of the adhesive layer 32 is powdered. A transfer sheet C is manufactured by fixing the hot melt resin 36, and the transfer sheet C is placed so that the hot melt resin 36 is in contact with a desired surface of the transfer target 37, and is heated and pressed to transfer the hot melt resin 36 to the transfer target. It is known that the transfer substrate 34 is peeled off by being fused to the object 37 (see Japanese Patent Publication No. 2-24239).

[0004]

By the way, since the thermal reversal type flocked transfer material shown in FIG. 18 is for reversing and thermal transfer, the short fibers temporarily attached to the peeling base material 20 through the temporary adhesive layer 21. The length of 22 cannot be increased, the lengths of the short fibers 22 must be the same, and the flocked layer 23 cannot have irregularities or the like, which is not preferable in terms of aesthetics. There was a drawback.

In addition, the method of thermal transfer flocking applique shown in FIGS. 19 to 24 requires a wasteful process for removing the powdery hot melt resin 36 adhering to the short fibers 33. If left as little as possible in 33, the short fibers may not be three-dimensionally transferred and the texture may be deteriorated. Also, the adhesive which is the film layer 5 of the laminated sheet B at the tip of the short fibers or The hot-melt resin remains adhered to deteriorate the aesthetic appearance, and the hot-melt resin is adhered to the adhesive layer 32 by adhering the particles of the hot-melt resin 36 to the adhesive layer 32 after the peelable base material 1 is peeled off. Since a means for attaching 36 is required, the short fibers 33 temporarily attached to the film layer 5 may be displaced.

The present invention has solved the above-mentioned problems and is capable of accurately and quickly transferring a mark having a desired shape and color to a desired position and further providing an adhesive agent on the tip of the flocked layer. It is possible to obtain a beautiful pattern without sticking of, and it is possible to process a complicated pattern without problems, and it is possible to transfer flying patterns separated by the pattern as it is, and also a processing material is required An object of the present invention is to provide a thermal transfer appliqué which is convenient to use and easy to manufacture, such as a pattern portion without loss as in the prior art, and a manufacturing method thereof.
