Next, on top of the colored short fibers 13 on which the patterned colored layer 9 has been formed, the tips 5 of the colored short fibers 13 are glued with a glue-like adhesive that has stronger adhesive force and elasticity than the temporary adhesive layer 2. The patterned adhesive layer 6 is formed in such a state that the patterned adhesive layer 6 is buried. Next, a hot melt agent 15 in the form of hot melt resin particles or powder is adhered to the entire surface of the pattern adhesive layer 6 while the pattern adhesive layer 6 is in the form of a paste and has not yet dried, and the solvent of the paste adhesive is evaporated. This is characterized in that a hot melt adhesive layer 7 is formed on the surface.

<<Example>> Hereinafter, an example of the method for manufacturing a heat reversal type flocked transfer fabric of the present invention will be described with reference to the drawings.

In the first step, as shown in FIG. 2, a glue-like adhesive that strongly adheres to the release film 1 is applied to the entire surface or necessary parts of the heat-resistant, transparent and tough release film 1. The temporary adhesive layer 2 is formed by coating by screen printing, spraying, or other means.

In the second step, as shown in FIG. 3, a colorless temporary adhesive bond 2 made of a glue-like adhesive that strongly adheres to the release mother film 1 formed in the first step is applied to rayon, nylon, Tetron, polyester, etc. Short fibers 3 having a length of about 0.3 mm to 3 mm made of a material such as the like are flocked in a dense and upright state by electrical or mechanical means to form a flocked layer 4, and then by heat drying or other means. The short fibers 3 are temporarily attached to the temporary adhesive layer 2 by evaporating the solvent of the adhesive of the temporary adhesive layer 2, and the flocked fabric 2 is
form 1.

In the third step, as shown in FIGS. 4 and 6, colorants 12 such as pigments and dyes are applied to the flocked layer 4, which is densely and uprightly flocked in the second step, using a screen plate 10 or other printing means. The short fibers 3 are colored to form a pattern-colored layer 9 with the required pattern or letter shape, and the colorless temporary adhesive layer 2 is also colored with the pattern-colored layer 9.
A colored temporary adhesive layer 16 is formed in the same color and shape.

In addition, in the fourth step, as shown in FIG.
A glue-like adhesive having stronger adhesive force and elasticity than the temporary adhesive layer 2, such as vinyl acetate type, acrylic type, A pattern adhesive layer 6 is formed using latex or the like in such a manner that the tips 5 of the colored staple fibers 13 are buried.

In the fifth step, the pattern adhesive layer 6 is pasted on the entire surface of the pattern adhesive layer 6 formed with a glue-like adhesive that has strong adhesive strength and elasticity, and the necessary designs or letters are attached in the fourth step.The pattern adhesive layer 6 is pasty and does not dry. A hot melt agent 15 in the form of hot melt resin particles or powder is partially embedded in the pattern adhesive layer 6 and is dispersed to bond it with high density, and in the fifth step, the pattern formed in the fourth step as shown in FIG. In order to fix the paste-like adhesive having strong adhesive force and elasticity of the adhesive layer 6 and the hot melt agent 15 sprinkled thereon, the solvent of the paste-like adhesive having strong adhesive force is heated or by other means. The adhesive and the hot melt agent 15, which are dried and have a strong adhesive force, are fixed to the pattern adhesive layer 6, and the hot melt agent 15 in the form of hot melt resin particles or powder adhering to the areas other than the required pattern adhesive layer 6 is then brushed. Remove by other means.

In the sixth step, as shown in FIG. 8, after removing the hot melt agent 15 that has adhered to areas other than the patterned adhesive layer 6 in the fifth step, a necessary heating step is carried out to create an adhesive with strong adhesive force. The adhesive force of the pattern adhesive layer 6 is strong, and the hot melt agent 1
5 is in a semi-dissolved state and adheres to the patterned adhesive layer 6, forming a hot melt adhesive layer 7 with an uneven surface 8.

Further, 18 is a piece of a transfer member, 19 is a pattern, 21 is a member to be transferred, and 20 is a processed surface of the member to be transferred 21. Reference numeral 14 denotes a pattern adhesive layer formed into two layers by providing a pattern adhesive layer 6 and a hot melt adhesive layer 7.

In addition, the peeling mother film 1 has high transparency and does not change its physical properties at the transfer temperature during thermal transfer, and is recognized for its safety and hygiene properties due to its strong mechanical properties and chemical resistance that can withstand peeling resistance during transfer. It uses a film that has been

For example, the usable temperature for polyester film is generally said to be -70℃ to +150℃, but its melting point is 260℃ or higher, and for a short period of time it can be used at approx.
Use a material that can withstand temperatures of 200°C.

In addition, when the temporary adhesive layer 2 and the release film 1 peel off the heat transfer release film 1, the temporary adhesive layer 2 does not separate from the release film 1 and remain on the surface of the pattern 19. There is a need to. That is, it is necessary to use an adhesive suitable for adhering the film surface. For example, adhesives should be devised that are mainly made of urethane, ionomer water-based resin, aromatic polyester ionomer water-based resin, etc., and whose adhesive strength is adjusted according to the purpose of use as a temporary adhesive.

In other words, as an adhesive for temporary bonding.Formulation example: A solution of 2.5 to 3 parts of sodium alginate in 100 parts of water, 60 parts of polyester ionomer water-based resin, 24 parts of acrylic water-based resin, 16 parts of the resin glue with the above composition, and adjusted the viscosity with aqueous ammonia. Used as adhesive for temporary adhesive layer.

It is also effective to roughen the film surface by sanding, blasting, etc. to form a finely roughened surface 17, and to physically increase the adhesive effect on the film surface to strengthen the adhesive force. As a result, the 12th
A beautiful pattern 19 can be obtained without the peeling mother film 1 and the temporary adhesive layer 2 separating from each other and remaining on the surface of the pattern 19 during peeling as shown in the figure.

Further, the adhesive for the temporary adhesive layer 2 needs to be colorless in order to form a colored temporary adhesive layer 16 colored in the same shape as the pattern colored layer 9 with a coloring agent 12 such as a pigment or dye.

≪Operations and Effects of the Invention≫ The present invention has the above-described structure, and a colorless glue-like adhesive that strongly adheres to the heat-resistant, transparent and tough release film 1 is coated to form a colorless temporary film. An adhesive layer 2 is formed. Next, colorless short fibers 3 made of a material such as rayon, nylon, Tetron, polyester, etc. are flocked in a dense and upright state on the entire surface of the temporary adhesive layer 2 while the temporary adhesive layer 2 is pasty and has not yet dried. A flocked layer 4 is formed, and the solvent of the glue-like adhesive is evaporated to temporarily attach the short fibers 3 to the release mother film 1, and the temporary adhesive layer 2 and the release mother film 1 are bonded together.
and fix it. Next, by printing on the flocked layer 4, the short fibers 3 are colored with a coloring agent 12 such as a pigment or dye so as to form a colored layer 9 with a desired pattern or letter-like pattern, and the colorless temporary adhesive layer 2 is also colored. Pattern colored layer 9
A colored temporary adhesive layer 16 is formed in the same color and shape. Next, the colored short fibers 1 on which the patterned colored layer 9 was formed
3, a patterned adhesive layer 6 is formed using a glue-like adhesive having stronger adhesive force and elasticity than the temporary adhesive layer 2, with the tips 5 of the colored short fibers 13 buried therein. do. Next, a hot melt agent 15 in the form of hot melt resin particles or powder is adhered to the entire surface of the pattern adhesive layer 6 while the pattern adhesive layer 6 is in the form of a paste and has not yet dried, and the solvent of the paste adhesive is evaporated. By forming a heat-reversible flocked transfer fabric 21 by forming a hot-melt adhesive layer 7 on the surface, a pattern 19 corresponding to the pattern colored layer 9 can be transferred to the surface to be processed, which is a transfer member 11 such as clothing such as a T-shirt. 20, the hot melt adhesive 7 of the transfer member piece 18 having the required pattern colored layer 9 is brought into close contact with the surface to be processed 20, and the hot melt adhesive layer 7 is melted with a heating device such as an iron. When heated at a high temperature, the melted hot melt adhesive layer 7 flows into the texture of the processed surface 20 of the transferred member 11, and as the processed surface 20 cools after heating, the hot melt adhesive layer 7 that has flowed in flows into the texture of the processed surface 20 of the transferred member 11. The hot melt adhesive layer 7 flows into the structure of the processed surface 20, and as the processed surface 20 cools after being heated, the hot melt adhesive layer 7 that has flowed in is fixed and becomes a strong adhesive state.

Next, when the surface to be processed 20 has cooled down and the release base film 1 is peeled off as shown in FIG. By doing so, it is possible to form a beautiful three-dimensional pattern with strong adhesion, and furthermore, it is easy to transfer to the transfer target member 11 having elasticity, and the transfer target member 11 can be easily expanded and contracted. At this time, the gaps between the colored short fibers 13 are appropriately adjusted by the pattern adhesive layer 6 to prevent the colored short fibers 13 whose tips 5 are embedded in the pattern adhesive layer 6 from falling off, thereby obtaining a three-dimensional and beautiful pattern. It is something that can be done.

Further, the release mother film 1 is heat resistant, does not deform due to heat, is strong, and is transparent.
Furthermore, since the colored temporary adhesive layer 16 is colored in the same shape and the same color as the patterned colored layer 9 made of colored short fibers 13, the colored temporary adhesive layer 16 can be clearly seen through from the back side.
The orientation of the pattern-colored layer 9 and the clothing to be transferred can be thoroughly considered before pasting, and the pasting position can be easily confirmed and there is no failure when transferring and pasting onto the transfer target member 11. It can be transferred and is easy to handle and can be attached to expensive clothing with peace of mind, but the pattern 19 with an unsuitable shape or color may be transferred and ruin the high-end clothing. There is no.

In addition, by making the short fibers 3 that formed the temporary adhesive layer 2 and the flocked layer 4 colorless, when coloring the pattern colored layer 9 and the colored temporary adhesive layer 16 in a desired color with the coloring agent 12, it is possible to create a pattern. Colored layer 9 and colored temporary adhesive layer 1
The color of the colored temporary adhesive layer 16 and the patterned adhesive layer 9 when viewed through the transparent release film 1 during transfer is not different from that of the patterned adhesive layer 9, and the pattern 19 is of the desired color. It can be transferred without failure.

Furthermore, it has a very 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, which has many industrial effects.
