Then, it becomes a finished state as a transfer member piece 27, which is a transfer product that can be thermally transferred clearly and clearly.

In addition, Figures 18, 19, and 20 show the multicolored short fiber flocked layer 1.
18, first, as shown in FIG. 18, a first screen 4 provided with a first mesh 23 of positive electrodes passing through the first colored short fibers 5 is temporarily bonded. layer 2
is interposed between the peeling film placed on the cathode plate 20 and the sieve surface 24, and the first colored short fibers 5 placed inside the sieve surface 24 are introduced and dropped to the first desired location 3. Further, as shown in FIG. 19, a second screen 7 having a second anode mesh 25 that passes through the second colored short fibers 8 is coated with temporary adhesive Wi2 and placed on the cathode plate 20. m2 interposed between the placed release film and the sieve surface 24 and placed inside the sieve surface 24.
A third screen 10 is provided with a third mesh 26 of positive electrodes, which is filled with colored short fibers 8 and allowed to fall, and is planted at the second desired location 6, and which passes through the third colored short fibers 11 as shown in FIG.
The temporary adhesive layer 2 is applied, and the third colored short fibers 11 are placed between the release film placed on the cathode plate 20 and the sieve surface 24, and the third colored short fibers 11 are placed inside the sieve surface 24 and allowed to fall. , a multicolor A-fiber flocked layer 12 is formed by flocking at the third desired location 9.

Note that 28 is a member to be transferred, 29 is a processed surface of the member to be transferred 28, and 44 is a superheater. Furthermore, by forming the pattern adhesive Wi15 while leaving the peripheral edge 30, a beautiful three-dimensional pattern can be obtained on the peripheral edge 32 of the multicolor pattern plate 31 during thermal transfer.

In addition, the release base film that forms the release base material 1 has high transparency, does not change its physical properties at the transfer temperature during thermal transfer, and has strong mechanical properties and chemical resistance that can withstand peeling resistance during transfer. This film uses a film whose safety and hygiene properties have been confirmed.

For example, the processing temperature for polyester film is generally said to be -70°C to +150°C, but the melting point is 260°C or higher, and a material that can withstand temperatures of about 200°C for a short period of time should be used. Should.

Furthermore, when the temporary adhesive layer 2 and the release base film are peeled off after heat transfer, the temporary adhesive layer 2 does not separate from the release base film and remain on the surface of the reversed multicolor pattern 31. It is necessary to make some efforts. That is, it is necessary to use an adhesive suitable for adhering the film surface. For example, adhesives should be designed that are mainly made of urethane, fluorocarbon aqueous resins, aromatic polyester fluorocarbon aqueous resins, etc., and whose adhesion strength is adjusted according to the purpose of the temporary adhesive, and which becomes transparent when dry.

For example, 60 parts of a solution of 2.5 to 3 parts of sodium alginate to too much water, 24 parts of polyester ion/mer water-based resin, 16 parts of acrylic water-based resin, and adjust the viscosity of the resin glue with the above composition with ammonia water to form a temporary adhesive layer 2. Used as an adhesive for

Functions and Effects of the Invention The present invention has the above-described structure, in which a paste-like adhesive that strongly adheres to the heat-resistant and strong peeling material 1 is applied to form a temporary adhesive layer 2, and then a temporary adhesive layer 2 is formed. The first colored short fibers 5 are flocked to the first desired location 3 of the temporary adhesive WI2 through the first screen 4, and then the second colored short fibers are implanted to the second desired location 6 of the temporary adhesive layer 2 through the second screen 7. The short fibers 8 are flocked, and then the third fibers are attached to the temporary adhesive layer 2 at the third desired location 9 through the third screen 10.
A desired beautiful multicolored short fiber flocked layer 12 is obtained by flocking the colored short fibers 11 to form a multicolored short fiber flocked rI112.
is formed by a simple method, and on top of the flocked short fibers m13 on which the multicolored short fiber flocked layer 12 is formed, the flocked short fibers 13 are bonded using an adhesive having stronger adhesive force and elasticity than the temporary adhesive layer 2. A pattern adhesive layer 15 is formed in a state where the tip portion 14 is buried, and then a hot melt adhesive layer 1 is applied to the pattern adhesive layer 15 using a hot melt agent in the form of hot melt resin particles or powder.
6, the pattern 31 corresponding to the pattern adhesive layer 15 is transferred to the transferred member 2 such as clothing such as a T-shirt or bag.
8, the surface of the transfer member piece 27 provided with the hot melt adhesive layer 16 is brought into close contact with the surface to be processed 29, and as shown in FIG.
For example, when the hot melt adhesive layer 16 is applied to the surface of a fabric, which is clothing such as a T-shirt, and heated with a heater 44 such as an iron to a temperature at which the hot melt adhesive layer 16 melts, the melted hot melt adhesive layer 16 is applied to the surface of the transfer member 28. flows into the structure of the processed surface 29,
After heating, the surface 29 to be processed cools, and the hot melt adhesive layer 16 that has flowed in is fixed and becomes a strong bond.

Next, when the surface 29 to be processed has cooled down and the base material 1 for peeling is peeled off as shown in FIG. With this, it is possible to form a three-dimensional pattern with strong adhesion, beautiful texture, sharpness, and multicolor, and furthermore, it is easy to transfer to the transfer target member 28 having elasticity. When the transferred member 28 expands and contracts, the gap between the colored short fibers 43 is appropriately adjusted by the pattern adhesive N15, and the flocked short fibers J4113 whose tips 14 are embedded in the pattern adhesive Nj15 are prevented from falling off, resulting in a three-dimensional and beautiful image. It is possible to obtain a unique pattern.

Furthermore, it has an extremely simple structure, is suitable for mass production, can be provided at low cost, and can be easily transferred by women and girls using an iron.

If the release material 1 is made of a heat-resistant synthetic resin, such as a transparent polyester resin film, it will not be deformed by heat during the adhesion process and will be strong, and the multicolored short fiber flocked layer 12 will be strong. It can be clearly seen through from the back side, and the orientation of the multicolored short fiber flocked layer 12 and the clothing to be transferred can be fully considered before pasting, and the transferred member 2
8, it is easy to check the attachment position and the transfer work can be done without failure, and it is easy to handle and can be applied to expensive clothing with peace of mind.It is used in many industries. This is effective.
