Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat-reversible flocked transfer fabric that is convenient to use. Conventionally, the short fibers of the flocked layer of a heat-reversible flocked transfer fabric are colored, and pigments of the required color are added to acrylic. There are products that are colored by mixing resins such as vinyl acetate, latex, urethane, and other resins, and using the adhesive strength of the mixed resin, the pigment is fixed in a film form on the surface of the short fibers that form the flocked layer. The average particle size of the pigment is 0.5 microns.
The particles, together with the adhesive, adhere to the surface of the short fibers in the form of a film, causing the short fibers to harden and impair the texture of the flocked layer. It is also a dyeing method that takes advantage of the sublimation properties of disperse dyes, which causes the dye to undergo a remarkable sublimation phenomenon using heat, and dyes the implanted short fibers with dye particles by sublimation. Stable dyeing is achieved by selecting and using highly disperse dyes, but the short fiber materials that can be dyed are limited to nylon and polyester fibers. Since the physical properties of the nylon and polyester materials change when heated above 190°C, it is necessary to select an acid-separating dye that undergoes a noticeable sublimation phenomenon at temperatures below that temperature to dye the short fibers. Next, the hot melt member necessary for heat reversal is provided to finish the product, and during reversal transfer, the provided hot melt member is melted by heat, and transfer adhesion is performed using the adhesive force of the hot melt member. However, when reversing the current hot melt member, It is necessary to heat the solution at a temperature of about 160°C to 180°C for about 15 to 25 seconds. Therefore, due to the amount of heat generated by the temperature at the time of reversal, the disperse dye sublimes again, and dyeing occurs in the necessary transfer pattern or character area and its surroundings, resulting in dye transfer. In addition, the sublimation rate differs depending on the color (yellow, red, etc. sublimate quickly), and the product has an unstable dyeing state, and the sublimation phenomenon will gradually occur at room temperature even in the patterns and letters after transfer and on the product before transfer. This progresses and long-term storage is impossible.

This invention was invented to solve the above-mentioned drawbacks and express patterns and characters in beautiful colors with higher precision than conventional products. Short fibers 3 made of a material such as rayon, nylon, polyester, Tetron, etc. are densely flocked to the temporary adhesive layer 2 to form a flocked layer 4, and the desired short fibers 3 and the temporary adhesive layer 2 are penetrated. Semi-liquid dyes of different colors such as yellow, red, and indigo to be adsorbed are applied to the short fibers 3 in various halftone dots only in the amount to be absorbed and absorbed, thereby forming a pattern dyed layer 9. In addition to embedding the tips 5 of the short fibers 3, a patterned adhesive layer 6 having stronger adhesive force and stretchability than the temporary adhesive layer 2 is provided, and the patterned adhesive layer 6
The present invention relates to a heat reversible flocked transfer fabric characterized in that a hot melt adhesive 7 is provided to form an adhesive layer 25 and a surface 8 is roughened. An example of the manufacturing process will be described below with reference to the drawings.

In the first step, as shown in FIG. 2, a paste-like adhesive with relatively weak adhesive strength is applied to the entire surface or necessary parts of a strong peeling base material 1 such as high-quality paper, cloth, nonwoven fabric, etc. 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 length of material such as rayon, nylon, Tetron, polyester, etc. is formed on the temporary adhesive layer 2 formed with the relatively weak glue-like adhesive formed in the first step. 0.3mm~3
The flocked layer 4 is formed by flocking the short fibers 3 of about mm in a high density and in an upright state by electrical or mechanical means, and then a glue-like adhesive with relatively weak adhesive strength is formed by heat drying or other means. Evaporate the solvent and release the base fabric 1
to be fixed to.

In the third step, as shown in FIG. 4, FIG. 5, FIG. 6, and FIG. 1. Using a screen plate 10 or other printing means, the short fibers 3 and the temporary adhesive layer 2 are coated with a first semi-liquid dye 12 such as yellow to form a first pattern layer 11 having a desired pattern or character shape. Although it is dyed,
The surplus first semi-liquid dye 12 present between the short fibers 3, 3... evaporates, and the first dyed short fibers 13 and the first pattern dyed temporary adhesive layer 29 are obtained, which are penetrant-dyed with the first semi-liquid dye 12. It is something that can be done.

8, 9, 10, 11 in the 4th step.
As shown in the figure, a required pattern or character shape is created using a second semi-liquid dye 15 such as red using a second screen plate 14 with second halftone holes 33 provided in the flocked layer 4 or other printing means. Although the short fibers 3 and the temporary adhesive layer 2 are dyed to form the second pattern layer 16, the surplus second fibers existing between the short fibers 3, 3...
As the semi-liquid dye 15 evaporates, the second dyed short fibers 26 and the second dyed staple fibers 26 are dyed with the second semi-liquid dye 15.
A patterned dyed temporary adhesive layer 30 can be obtained.

In the fifth step, as shown in FIGS. 12, 13, 14, and 15, third halftone holes 3 are formed in the flocked layer 4.
Using a third screen plate 17 provided with 4 or other printing means, the short fibers 3 are printed using a third semi-liquid dye 18 such as indigo blue to form a third pattern layer 19 having a desired pattern or letter shape. and the temporary adhesive layer 2, the surplus third semi-liquid dye 18 existing between the short fibers 3, 3... evaporates and the third dyed short fibers 18 are dyed by the third semi-liquid dye 18. The fibers 27 and the third pattern dyed temporary layer 31 can be obtained.

Therefore, the first semi-liquid dye 12 and the second semi-liquid dye 1
5. The color of the mixed part of beautiful different colors, which has a part dyed with each of the third semi-liquid dyes 18 and a heavy color part 38 dyed by mixing the three colors, forms a pattern dyed layer 9 in which the color is blurred. However, in Figures 19 and 20, the first, second, and third screen versions 1
0, 14, 17 first, second, third halftone hole 3
19 is an enlarged view of the first, second and third halftone dot patterns 35, 36 and 37 formed by one of the first, second and third semi-liquid dyes 12. , 15, 18 are shown in the upper part of the flocked layer 4, and FIG. 20 shows the state in which they are sequentially dyed.

By the way, it is not limited to the number of steps mentioned above, but once ~
The pattern dyed layer 9 may be formed by adding black color using a black plate to adjust the number of appropriate steps and gray balance.

In addition, in the sixth step, as shown in FIG. 18, on the short fibers 3 on which the pattern dyed layer 9 has been formed, a paste-like adhesive having a stronger adhesive force than the temporary adhesive layer 2 is applied by a screen method, a spray method, or other means. The patterned adhesive layer 6 is formed using an adhesive such as vinyl acetate, acrylic, latex, etc. in such a manner that the tips 5 of the short fibers 3 are buried therein. In the seventh step, a hot melt agent 20 in the form of hot melt resin particles or powder is sprinkled on the pattern adhesive layer 6 formed of a glue-like adhesive with strong adhesive force and layered on the necessary designs or letters in the sixth step. In addition to bonding with high density, in the eighth step, as shown in FIG. In order to fix the sprayed hot melt agent 20, the solvent of the glue-like adhesive having strong adhesive force is dried by heating or other means, and the adhesive having strong adhesive force and the hot melt agent 20 are fixed. The hot melt agent 20 in the form of hot melt resin particles or powder adhering to areas other than the patterned adhesive layer 6 is removed by means such as brushing. In the ninth step, the second
As shown in Figure 0, after the hot melt agent 20 adhering to the parts other than the pattern adhesive layer 6 is removed in the eighth step, the necessary heating (baking process or curing process) process is carried out to ensure strong adhesive strength. The adhesive force of the pattern adhesive layer 6, which is an adhesive, becomes strong, and the hot melt agent 20 becomes semi-dissolved and adheres to the pattern adhesive layer 6 to form a hot melt adhesive 7, and the surface 8 is roughened to form a pattern. The product is finished in such a way that lines and dots can be heat-transferred clearly and clearly.

Other details will be explained with reference to embodiments as shown in Fig. 25 and Fig. 2.
As shown in Fig. 6, a hot melt adhesive 20 is mixed in advance into the patterned adhesive layer 6, which is a strong adhesive in the sixth step of the above embodiment, and the hot melt adhesive is applied by a screen method, a spray method, or other means. forming a pattern adhesive layer 6 provided with 7;
The seventh step by performing heat treatment etc.
This eliminates the need for the 8th public process.

Note that 21 is a member to be transferred, and 22 is a surface to be processed of the member 21 to be transferred. Also, 23 is a pattern, 2
4 is a transfer member piece.

In addition, by using a semi-liquid dye as a coloring agent, the particle size of pigments conventionally used as a dyeing agent is about 0.5 microns,
Since the dye particles are minute particles of about 0.005 microns, even when printing using a screen plate, processing with a screen plate with high mesh accuracy is easy. By the way, when processing with pigments, the screen mesh is limited to about 120 meshes, but with dyes, high meshes of 250 meshes or more and screen plates can be used.

From this point of view as well, printing accuracy increases dramatically, and unlike coloring methods that use pigments to form a colored resin film on the surface of the short fibers, the inside of the short fibers 3 is colored. Since the dye particles are directly penetrated and adsorbed, highly accurate patterns and letters can be created with beautiful colors without compromising the texture. The dyes used include acid dyes, direct dyes, reactive dyes, naphthol dyes, sulfur dyes, threne dyes, cationic dyes, complex salt dyes, oxidative dyes, basic dyes, and others, but dyes that involve a sublimation phenomenon such as disperse dyes It is not used.

In addition, it is a product that has the characteristic that only the required pattern part of the short fibers 3 temporarily attached with high density can be transferred from the release base material 1 by heat, and it can be used for general fiber cloth,
The method of dyeing is basically different from that for dyeing vettin, pile cloth, etc. Even in printing, semi-liquid dyes are printed in an amount exceeding the amount necessary to color the implanted short fibers 3. The semi-liquid dye evaporates in such an amount that no excess dye remains in between, so in screen printing, the clay of the semi-liquid dye is adjusted (approx.
4000 centipoise).

This invention has the above-mentioned structure, in which a temporary adhesive layer 2 is provided on the entire surface of the release base material 1, and short fibers 3 made of a material such as rayon, nylon, polyester, Tetron, etc. are attached to the temporary adhesive layer 2 at a density. The flocked layer 4 is formed by temporarily flocking the flocks, and semi-liquid dyes of different colors such as yellow, red, and indigo are permeated and adsorbed into the desired short fibers 3 and the temporary adhesive layer 2. A pattern dyed layer 9 and a pattern dyed temporary adhesive layer 28 are formed by dot coating in a variety of colors only in the amount that permeates and adsorbs into the pattern. By providing the pattern adhesive layer 6 having a stronger adhesive force than the adhesive layer 2 and providing the hot melt adhesive 7 on the pattern adhesive layer 6, the pattern 23 corresponding to the pattern dyed layer 9 can be printed on a T-shirt, etc. clothing,
In order to perform transfer formation on a processed material 22, which is a transferred member 21 such as a bag, the surface 8 of the adhesive layer 25 of the transfer member piece 24 provided with the required pattern dyed layer 9 is brought into close contact with the processed surface 22. Incidentally, since the surface 8 of the adhesive layer 25 is made rough, this rough surface does not slip when placed on the surface 22 to be processed, and a portion of the rough surface covers the transfer member 21 as shown in FIG. It bites into the surface of textiles such as T-shirts and other clothing to ensure transfer work at the desired position.When heated with a heating device such as an iron to a temperature at which the hot melt adhesive 7 melts, the hot melt adhesive 7 melts. The adhesive 7 flows into the structure of the processed surface 22, and as the processed surface 22 cools after being heated, the hot melt adhesive 7 that has flowed in is fixed and becomes a strong adhesive state.

Next, when the surface 22 to be processed has cooled, when the base fabric 1 for peeling is peeled off as shown in FIG.
By flowing into the processed surface 22, it is possible to strongly adhere and form a beautiful three-dimensional pattern, and furthermore, it is easy to transfer to a material to be transferred that has elasticity. When the transferred member expands and contracts, the gap between the short fibers 3 is adjusted appropriately by the pattern adhesive layer 6, and the short fibers 3 whose tips 5 are embedded in the pattern adhesive layer 6 are prevented from falling off, resulting in a three-dimensional and beautiful image. It is possible to obtain a pattern.

Furthermore, the structure is extremely simple, suitable for mass production, and can be provided at low cost. Women and women can easily transfer the pattern using an iron, and the dyed pattern layer 9 is the same as the flocked layer 4. The short fibers 3 are dyed with a semi-liquid dye of a different color that is penetrated and adsorbed into the temporary adhesive layer 2, and the pattern-dyed temporary adhesive layer 28 is formed, making the short fibers 3 beautiful as a whole. It is possible to obtain the three-dimensional pattern 23 of the pattern 23, which has a clear color and has a blurred texture in the mixed part of different colors. To obtain a product with high commercial value without the need for wasteful labor to remove the dye during manufacturing without leaving wasteful dye by coating and forming it in a variety of colors only in the amount that penetrates and adsorbs into the dye. It has many industrial effects, such as the ability to
