Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat reversible flocked transfer fabric that is convenient to use.
As a colored product, the pigment of the desired color is mixed with other resins such as acrylic, vinyl acetate, latex, and urethane, and the mixed U (Using the adhesive strength of the fat, the pigment forms a flocked layer. There is a type of short T-shirt and navy blue that is colored by fixing it in a film form on the surface, but the average particle size of the pigment is 0.
At 5 microns, the particles will adhere to the surface of the short fibers together with the adhesive 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. Select and use highly disperse dyes to achieve stable dyeing, or dyeable short M
Materials for iLMt are limited to nylon and polyester fibers. Since the physical properties of the materials nylon and polyester change when heated above about 190°C, it is necessary to select a disperse dye that causes a noticeable sublimation phenomenon at temperatures below that temperature to dye the short fibers. Next, the hot melt material necessary for heat reversal is provided to finish the product, and during reversal transfer, the hot melt material provided is melted by heat and transfer adhesion is performed using the adhesive force of the real melt material, or the current hot melt material is The melting temperature when inverting the part is 160°C to 180°C
It is necessary to heat it for about 15 to 25 seconds at a low temperature. 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 varies depending on the color (especially yellow, red, etc. sublimate quickly), and the product has an unstable dyeing state.The sublimation phenomenon may gradually occur at room temperature in patterns and letters after transfer, and in the product before transfer. This progresses and long-term storage is impossible.

This invention was invented to solve the above-mentioned drawbacks and to express horizontal lines and characters in beautiful colors with higher precision than conventional products. The short fibers 3 made of a material such as rayon, nylon, polyester, Tetron, etc. are flocked to the temporary adhesive layer 2 with high density to form the flocked hair 14, and the desired short M&fibers 3 and the temporary adhesive layer 2 are attached. A semi-liquid dye of a different color such as yellow, red, indigo, etc., which is penetrated and adsorbed by the short fibers 3, is applied in various halftone dots to form a pattern dyed layer 9. A patterned adhesive layer 6 embeds the tips 5 of the positioned short fibers 3 and has stronger adhesive force and elasticity than the temporary adhesive N2.
The heat reversible flocked transfer fabric is characterized in that a hot melt adhesive 7 is provided on the pattern adhesive layer 6 to form an adhesive layer 25, and the surface 8 is roughened. An embodiment of the manufacturing process of the heat reversible flocked transfer fabric of the present invention will be described below with reference to the drawings.

In the first step, as shown in Fig. 2, a paste-like adhesive with a relatively weak adhesive strength is applied to the entire surface or necessary parts of the strong peeling base material 1, such as high-quality paper, cloth, nonwoven fabric, etc. The temporary adhesive layer 2 is formed by coating by a screen printing method, a spray method, 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. Short fibers 3 of about 0,3 m+n to 3a+m are flocked in a dense and upright state by electrical or mechanical means to form flocked hair WI4, and then glue-like with relatively weak adhesive strength is formed by means such as heat drying. Evaporate the adhesive solvent and fix the peeling base material.

In the third step, as shown in Figures 1, 5, 6, and 7, first halftone dot pattern holes 32 were provided in the flocked layer 4, which was densely and uprightly flocked in the second step. 1st screen version 10
or other printing methods to dye @1 semi-liquid dye such as yellow.
pjSi pattern layer part 1 with the patterns and letters required in 2.
The short fibers MF, 3 and the temporary adhesive layer 2 are dyed to form short fibers MF, 3, and the temporary adhesive layer 2. However, the excess first semi-liquid dye 12 present in the short fibers 3, 3... evaporates and dyes the first half It is possible to obtain the first dyed short fibers jA13 and the first pattern dyed temporary adhesive waste 29 which are penetrant-dyed with the fluid dye 12.

In the fourth step, as shown in FIGS. 8, 9, 10, and 11, the second #! A second semi-liquid dye 15 of red or the like is printed using a second screen plate 14 provided with dot pattern holes 33 or other printing means in a desired pattern or letter shape.
short fibers 3 and temporary adhesive layer 2 to form pattern layer portion 16;
The surplus second semi-liquid dye 15 existing between the short Mlj, fibers 3, 3, etc. evaporates and the second dyed short fiber a is penetrated and dyed with the second semi-liquid dye 15. , 26
And the second pattern dyed temporary adhesive layer 30 can be obtained.

In the fifth step, as shown in FIG. 12, FIG. 13, FIG. 14, and FIG.
A screen plate 17 or a third semi-liquid dye 18 such as indigo is used to create the required pattern or letter shape using the printing means of the pond.
short fibers 3 and temporary adhesive layer 2 to form pattern layer portion 19;
However, the excess third semi-liquid dye 18 existing between the short fibers 3, 3... evaporates and the third semi-liquid dye 18 is dyed. And the third pattern dyed temporary adhesive layer 31 can be obtained.

Therefore, the first semi-liquid dye 12, the second semi-liquid dye 15, and the third
(Pattern dyeing in which the colors of the beautiful mixed parts of different colors are blurred, including the parts dyed with each of the semi-liquid dyes 18 and the heavy-colored parts 38 dyed by mixing the three colors.) 19 and 20, the first, second, and third halftone dot pattern holes 32, 33, . The first formed by one piece of 34
, second and third halftone dot patterns 35, 36, 37, and FIG. 19 is an enlarged view of the first, second and third semi-liquid dyes 12.
15.18 represents the state located above the flocked layer 4,
FIG. 20 shows the state of sequential staining.

By the way, the number of steps is not limited to the above, and the pattern dyed layer 9 may be formed by using an appropriate number of steps, from one to several times, and by adding black color using a black plate to adjust the gray balance.

In addition, in the sixth step, as shown in FIG. 18, a stronger adhesive force than the temporary adhesive layer 2 is applied to the short fibers 3 on which the pattern dyed layer 9 is formed by a screen method, a spray method, or a spray method. The pattern adhesive layer 6 is formed by using a paste-like adhesive such as vinyl acetate, acrylic, latex, etc. so that the tips 5 of the short fibers 3 are buried therein. 6th in the 7th step
A hot melt agent 20 in the form of hot melt resin particles or powder is sprinkled onto the pattern adhesive layer 6 formed of a glue-like adhesive with strong adhesive force, which is layered on the required patterns or letters by the process, and In the 8th step, the 19th
As shown in the figure, the hot melt agent 20 sprinkled on the glue-like adhesive having a strong adhesive force of the patterned adhesive layer 6 formed into the shape Ifi in the sixth and seventh steps is fixed. In order to do this, the solvent of the paste-like adhesive having strong adhesive force is dried by heating or other means to fix the adhesive having strong adhesive force and the hot melt agent 20, and then the adhesive other than the required pattern adhesive layer 6 is dried. The true melt agent 20 in the form of particles or powder of the true melt resin adhering to the portion is removed by means such as brushing. In the ninth step, as shown in FIG.
After removing the hot melt agent 20 that has adhered to areas other than the pattern adhesive layer 6 during the process, a necessary heating (baking process or curing process) process is performed to form the pattern adhesive layer 6, which is an adhesive with strong adhesive strength. The adhesive force becomes strong, and the bot melt agent 20 becomes semi-dissolved and adheres to the pattern adhesive layer 6 to form the hot melt adhesive 7, and the surface 8 is roughened, so that the lines and dots that make up the pattern are clear and sharp. The product is ready for use as a product that can be thermally transferred.

To explain another embodiment, as shown in FIG. 25 and PJS2G, a hot melt agent 20 is mixed into the patterned adhesive layer 6 which is a strong adhesive in the sixth step of the above embodiment. By forming the pattern adhesive layer 6 provided with the hot melt adhesive 7 by the screen method, spray method, or other method, and performing heat treatment etc., the seventh step and the eighth step are unnecessary. This is what I did.

In addition, 21 is a member to be transferred, and 22 is a member to be transferred 21.
This is the surface to be machined. Further, 23 is a pattern, and 24 is a transfer member piece.

In addition, by using a semi-liquid dye as a coloring agent, the particle size of the pigment conventionally used as a dyeing agent is approximately (
There are about 1.5 microns, and compared to that, the dye particles are 0.
．． Since the particles are as small as 0.005 microns, they can be easily processed using a screen plate with high mesh accuracy even when printing using a screen plate. By the way, the screen mesh when processing with pigments is 12.
The limit is around 0 mesh, but for dyes, high mesh is higher than 250 mesh, use of screen plate or nf
It is Noh.

From this point of view as well, the printing accuracy increases dramatically, and unlike the method of coloring using pigments, which forms a colored resin film on the surface of the short fibers 1), the short fibers 3. Because the dye particles are directly penetrated and adsorbed into the interior, highly accurate patterns and letters can be created without compromising the texture. Dyes used include acid dyes, direct dyes, reactive dyes, naphthol dyes, sulfur dyes, threne dyes, cation dyes, complex salt dyes, oxidation dyes, basic dyes, and dyes that involve a sublimation phenomenon such as disperse dyes. is not used.

In addition, it is a product that has the characteristic that only the required pattern part can be transferred by heat from the peeling B↓ fabric 1, where the short I fibers 3 temporarily planted with high density can be transferred to general fiber cloth, veratin, and pile cloth. The method of dyeing is basically different from the dyeing method used for dyeing, etc. Also in printing, semi-liquid dyes do not print more than the amount necessary to color the implanted short fibers 3, and do not print excess dye on the short fibers 3. The semi-liquid dye evaporates in such an amount that no dye remains; therefore, in screen printing, the viscosity of the semi-liquid dye is adjusted (approximately 4.
000 centiboise).

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. yellow, which is temporarily attached to the flocked fibers to form the flocked layer 4, and which is permeated and adsorbed to the desired short fibers A3 and the temporary adhesive layer 2;
A unique semi-liquid dye such as red or indigo is applied to short fibers 3 and temporary adhesive layer 2.
A pattern-dyed layer 9 and a pattern-dyed temporary adhesive layer 28 are formed by applying various halftone dots in an amount that penetrates and adsorbs into the pattern-dyed layer 9.
In addition to embedding the tip portion 5 of the short #&fiber 3 located at , a pattern adhesive WJ 6 having a stronger adhesive force than the temporary adhesive layer 2 is provided, and a hot melt adhesive 7 is provided in the pattern adhesive layer 6. The pattern 23 corresponding to the pattern dyed layer 9 is T
In order to perform transfer formation on the processed surface 22, which is a transfer member 21 such as clothing such as a shirt or 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 coated. It 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 is used for clothing such as T-shirts, and it bites into the surface of the υ fabric to ensure transfer at the desired position.It melts when heated with a heater such as an iron at a temperature that melts the hot melt adhesive 7. hot melt adhesive 7
flows into the structure of the processed surface 22, and after heating, the liquid is added to the surface 22.
As it cools down, the true melt adhesive 7 that has flowed in is fixed and becomes a strong adhesive state.

Next, when the surface 22 to be processed is cooled and the base material 1 for peeling is peeled off as shown in FIG. By doing so, it is possible to form a beautiful three-dimensional pattern with strong adhesion, and it is also easy to transfer to a transfer target material that has elasticity, and when the transfer target material expands and contracts, it is possible to form a beautiful three-dimensional pattern. The gap between the short fibers 3 is appropriately adjusted 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, thereby making it possible to obtain a three-dimensional and beautiful 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.
forms the flocked layer 4, and the desired short fibers 3 and the temporary adhesive layer 2
Combined with the dyeing using a semi-liquid dye of a different color that is penetrated and adsorbed by the fibers, the entire short fiber 3 is beautifully dyed with vivid colors due to the formation of the adhesive layer 28 (h). At the same time, it is possible to obtain the three-dimensional pattern 23 with a blurred color in the mixed part of different colors and a 411ii improved texture.Furthermore, the amount of semi-liquid dye that permeates and adsorbs into the short fibers 3 and the temporary adhesive layer 2 is varied. By coating and forming the dye, there are many industrial effects such as no unnecessary dye remaining and the ability to obtain products with high commercial value without the need for unnecessary labor to remove the dye during manufacturing. It is something that plays.
