Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat-reversible flocked transfer fabric that is convenient to use. There are products that are colored by mixing acrylic, vinyl acetate, latex, urethane, or other resins, and using the adhesive strength of the mixed resin, pigments are fixed in a film on the surface of the short fibers that form the flocked layer. The average size of the pigment particles is 0.5 microns, and the particles adhere to the surface of the short fibers together with the adhesive, 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 dispersed dyes, but the short fiber materials that can be dyed are
Limited to nylon and polyester fibers. Since the physical properties of nylon and polyester materials change when heated above 190°C, it is necessary to select a disperse dye that undergoes a noticeable sublimation phenomenon at lower temperatures 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. Also, the sublimation speed differs depending on the color (yellow, red, etc. sublimate quickly)
It is a product with an unstable dyeing state, and the sublimation phenomenon gradually progresses even in the pattern and characters after transfer and the product before transfer at room temperature, making long-term storage impossible.

This invention was invented to solve the above-mentioned drawbacks and to express patterns and characters in clear colors with higher precision than conventional products. , rayon, nylon,
The flocked layer 4 is formed by flocking short fibers 3 made of a material such as polyester or tetoron to the temporary adhesive layer 2 with high density, and the desired short fibers 3 and the temporary adhesive layer 2 penetrate and adsorb. A pattern dyed layer 9 is formed by applying semi-liquid dye in a variety of colors in an amount that will permeate and adsorb into the short fibers 3, and the tips 5 of the short fibers 3 located in the pattern dyed layer 9 are buried and temporarily bonded. A patterned adhesive layer 6 having stronger adhesive force and elasticity than layer 2 is provided, and a hot melt adhesive 7 is provided on the patterned adhesive layer 6 to form an adhesive layer 25, and the surface 8 is made rough. The present invention relates to a heat reversible flocked transfer fabric characterized by the following, and one embodiment of the manufacturing process of the heat reversible 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 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 short fibers 3 of about mm in length in a high-density, 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, and FIG. The short fibers 3 and the temporary adhesive layer 2 are dyed with the fluid dye 12 so as to form the first pattern layer 11 of the required pattern or letter shape. The excess first semi-liquid dye 12 evaporates and becomes the first semi-liquid dye 12.
It is possible to obtain the first dyed short fibers 13 and the first pattern dyed temporary adhesive layer 29 which are penetrate-dyed.

In the fourth step, as shown in FIGS. 7, 8, and 9, a required pattern or character shape is applied to the flocked layer 4 using a second screen plate 14 or other printing means with a second semi-liquid dye 15. The short fibers 3 and the temporary adhesive layer 2 are dyed so as to form the second pattern layer 16, but the excess second semi-liquid dye 15 existing between the short fibers 3, 3... evaporates and Second semi-liquid dye 1
5 can obtain the second dyed short fibers 26 and the second pattern dyed temporary adhesive layer 30 which are penetrated dyed.

In the fifth step, as shown in FIGS. 10, 11, and 12, a required pattern or character shape is applied to the flocked layer 4 using a third screen plate 17 or other printing means with a third semi-liquid dye 18. The short fibers 3 and the temporary adhesive layer 2 are dyed so as to form the third pattern layer 19, but the surplus third semi-liquid dye 18 existing between the short fibers 3, 3... evaporates and It is possible to obtain the third dyed short fibers 27 and the third pattern dyed temporary adhesive layer 31 which are penetrant-dyed with the third semi-liquid dye 18.

Therefore, the first semi-liquid dye 12 and the second semi-liquid dye 1
5. A beautiful patterned dyed layer 9 is formed of a portion dyed with each of the third semi-liquid dyes 18 and a portion dyed with a mixture of the three.

By the way, it is not limited to the number of steps mentioned above, but once ~
The pattern dyed layer 9 is formed by several steps or an appropriate number of steps.

In addition, in the sixth step, as shown in FIG. 13, on top of 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 a strong adhesive force is dried by heating or other means, and the adhesive having a 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 first
As shown in Fig. 5, after removing the hot melt agent 20 attached to the parts other than the patterned adhesive layer 6 in the eighth step, a necessary heating (baking process or curing process) process is performed to obtain a strong adhesive force. 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.

Further, to explain other embodiments, Fig. 20 and Fig. 2
As shown in Figure 1, 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, 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 eighth step.

Note that 21 is a member to be transferred, and 22 is a surface to be processed of the member 21 to be transferred. Or the pattern, 24... 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 viscosity of the semi-liquid dye is adjusted (approximately
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 fibers at a high level, and only the amount of the semi-liquid dye of a different color that is penetrated and adsorbed into the desired short fibers 3 and the temporary adhesive layer 2 is absorbed into the 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 coating in various colors, and the tips 5 of the short fibers 3 located in the pattern dyed layer 9 are embedded, and an adhesive force stronger than that of the temporary adhesive layer 2 is formed. By providing the pattern adhesive layer 6 having a pattern adhesive layer 6 and providing the hot melt adhesive 7 on the pattern adhesive layer 6, the pattern 23 corresponding to the pattern dyeing layer 9 can be transferred to clothing items such as T-shirts, bags, etc. To perform transfer formation on the processed surface 22 of the member 21, 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 at the desired location.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 release base material 1 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. A three-dimensional pattern of pattern 23 with vivid colors can be obtained by dyeing the material, and the semi-liquid dye is applied in various colors only in the amount that permeates and adsorbs into the short fibers 3 and the temporary adhesive layer 2. As a result, there are many industrial effects such as no wasteful dye remaining and a product with high commercial value being obtained without requiring unnecessary labor to remove the dye during manufacturing.
