It is also an excellent product in many aspects such as cutting.

Conventionally, paper and vinyl are mainly used for printing. However, in recent years, printing on textile printing materials is increasing due to the development of various advertising techniques.

A typical example is a veneer, which is used to print using a wide format printer or a plotter.

However, this level of conventional printing fabric is only a coating to enable printing on one side of the fabric, the print quality is low, there is a lack of clarity or precision, as well as a disadvantage that the color fades quickly after printing. When cutting to the required size, there is a problem that the thread of the cutting part is loosened, there is a problem that the cost of the expensive and relatively time-consuming thermal cutting, and when installing and removing the advertisement is inconvenient.

It is also reusable many times, the material is soft, the image resolution is high, the picture quality is very good, and the printed image is prevented from fading. The product also includes a special method of adding gray coating on the back of the fabric. In addition, it is easy to decorate the window in the summer season, and when the window is damaged, the fabric and adhesive layer of the product play a role of fixing the debris to some extent, thereby protecting the human body to some extent.

It is also an excellent product in many aspects such as cutting.

Therefore, this product is a fabric adhesive print paper, which is a convenient product that can be attached and detached freely in various places such as commercial advertisement, home printer paper, poster advertisement, wallpaper decoration, advertisement using various cars, picket, postcard, bromide, etc. .

Looking at the preferred embodiment of the present invention in detail as follows.

1. For the fabric, it is best to use Polyester DTY (Draw Textured Yarn).

This is because Polyester DTY absorbs the coating solution more deeply than other types of fabrics, and the coating solution is present between the strands in the yarn when coating the coating solution that receives ink well in the manufacturing process of the product. This is to prevent the most deviation from the fabric.

In addition, since the print ink is evenly distributed in the coating liquid between the coating liquid absorbed deeply into the fabric and the yarn strands, it is possible to obtain a much better effect in expressing clarity and realism in the photograph.

The inclination is 75 denier / 36 filament weft yarn with 150 denier / 48 filament, and the inclination density is about 8,800 and the weft density is 72T per inch.

It is also possible to use warp 75 denia / 72 filament weft 75 denia / 72 filament.

The next step is to boil and quench the fabric so that the width of the fabric shrinks by 10% to 15%. There are many ways to boil, but JIG-type machines are used, especially when the width of the input fabric is 74 inches. Process for 7 hours to 8 hours while maintaining the temperature.

After going through this process, the fabric is reduced by quenching. After going through this process twice, the 74-inch fabric is sufficiently reduced to be 64-65 inches wide.

This increases the density of the fabric and keeps it very dense and dense without gaps between the thread strands, thereby preventing the coating liquid from penetrating to the opposite side of the coating side in a later coating process.

This is especially to prevent the curling of the fabric and the tunneling phenomenon between the fabric and the Fuji after the surface-coated product is laminated with Becker (Fuji).

Because the fabric absorbs moisture in different amounts, curling and tunneling occur when it comes into contact with paper. This aging can be given enough time to prevent the product from shrinking after lamination.

2. Make coating solution as the next step.

The coating solution is carried out here in two versions, the version for solvent based inks being referred to as "S" and the versions for dye based and pigment based inks and UV inks referred to as "R".

The coating solution is completed three days before use. This is to ripen for about three days, and also give the coating liquid enough time for the different components to react with each other.

Then, the rotational axis is put into a container containing the coating liquid at a high speed for about 30 minutes before use, and the coating liquid is sufficiently mixed, thereby sufficiently diluting the viscosity of the coating liquid and maintaining the white color evenly.

In particular, in the present invention, the "S" coating liquid is divided into different coating liquids as the primary coating liquid and the secondary coating liquid, and in the present invention, the "R" coating liquid is subjected to the first coating with the same coating liquid and then to the second coating.

The main components of the "S" coating solution are as follows.

<1st coating liquid>

Chemical characterization CAS NO WT% (100% in total) Ethylene vinyl acetate copolymer 24937-78-8 40-50 additive - Residual ratio water 7732-18-5 40-55

<2nd coating liquid>

Chemical characterization CAS NO WT% (100% in total) Polyurethane Resin 51-79-6 app.25 additive - Residual ratio Methyl alcohol 67-56-1 app.60

The main components of the "R" coating solution are as follows.

Chemical characterization CAS NO WT% (100% in total) Low molecular alcohol 67-56-1 60-75 Silicon dioxide (silica) 112945-52-5 8 to 12 additive mixture Residual ratio Polyacrylate copolymer - 10 to 15

3. The next step relates to the back treatment of the fabric, which is important in the present invention,

On the back side of the fabric, the first white coating of polyurethane resin and white pigment (hereinafter referred to as white coating) is applied, and the next step is gray coating of polyurethane resin and gray pigment (hereinafter referred to as gray coating). do.

The white coating on the back and the gray coating on the back is used as a coating for waterproofing umbrellas or sunshade due to strong water pressure. In the present invention, the adhesive to be applied in the following process is well applied, and the adhesive does not penetrate the fabric. It is to avoid.

When the adhesive penetrates the fabric, there is a problem of speeding up the time when the printed image on the front is discolored due to the volatility of the adhesive. In addition, the back white coating and the back gray coating serve to fix the thread, thereby preventing the thread from loosening when cutting the print paper to a certain standard and when performing roll cutting.

As it prevents the role of loosening the thread as described above, it is possible to reduce the cost because it does not have to be expensive and time-consuming heat cutting, and can be cut quickly and cheaply. In addition, this process is to prevent light from penetrating the fabric of the product and to block hot sunlight.

In particular, this process is to prevent the background color or the pictures or texts of the advertisements that are already attached when the product is attached to a certain place to be seen on the surface of the product.

And this process does not simply form a thin white coating layer and a thin gray coating layer, but because it uses a mixture of white pigments and gray pigments respectively, it can have the same effect as dyeing white and gray on the fabric. Therefore, the white coating on the front side (“S” coating, “R” coating) makes the white more white, and on the back, it doubles the effect on the gray coating. There is an easy spot to be removed cleanly with the fabric and adhesive without leaving gray spots.

In other words, it does not remove the existing advertisements, but adds them on top of them in many ways. In particular, after these processes, the surface coating When applying “S” coating or “R” coating, make sure to apply “S” coating or “R” coating on the reverse side, which is the reverse side of this process.

In this way, the back gray coated color does not affect or change the “S” or “R” coated white side, and the “S” or “R” coated white side by the back white coating is more intact. It can be kept white, and the characteristics can be properly maintained on the back gray coated surface for sun protection.

Existing vinyl products have been inconvenient to be re-installed after removing all the pasted advertisements and adhesive dregs, and have been expensive. In fact, when the vinyl products are removed, very thin layers of vinyl film are used to support the walls or advertisements. Construction and other tasks are not easy because they can damage already painted paints.

Therefore, by using the removable adhesive that is carried out in the post-processing process, the lamination is completed by attaching it to the beaker (Fuji), so that the existing wallpaper or painted parts can be easily removed without damaging the adhesive residues. It can be detached and attached several times, making it easy in many ways.

In particular, this process proceeds as follows.

<Back white coating>

Polyurethane resin and white pigment are mixed and used in ratio of 6 to 4. (Example: 30g of polyurethane resin + 20g of white pigment) 50g is used for one yard with a width of 65 inches.

When coating, the gap between the fabric surface and the knife for coating should be 0.8mm for the first knife and 1mm for the second knife. When drying the coating liquid, the room temperature of the drying chamber is maintained at 150 ℃ ~ 170 ℃.

The important thing here should be the same process as above. It's possible to get a whiter color by two thin coatings than a thick one at a time, and the back gray coating that follows this process is the white surface of the “S” coating and the “R” coating. This is because it can prevent the coming up as much as possible without affecting.

In addition, as described above, it is possible to maximize the role of fixing the seal so that it does not loosen, and since the double layer is formed, it is possible to prevent the adhesive from penetrating into the surface.

<Back gray coating>

Polyurethane resin and gray pigment are mixed and used in ratio of 6 to 4. (Example: 30g Polyurethane Resin + 20g Gray Pigment) 50g per yard 65 inches wide.

Knife spacing is 0.5mm for primary knife and 0.8mm for secondary knife for coating. When drying the coating solution, the room temperature of drying chamber is maintained at 150 ℃ ~ 170 ℃.

This process is sufficient once, because the gray pigment used for the back gray coating, unlike the previous white back coating, is relatively saturation in its color itself, so a single thin process is sufficient.

4. As a next step, this process involves coating the surface of the product that will absorb the ink, using different versions of the “S” coating solution or “R” coating solution, as mentioned above. In particular, these processes allow the "S" coating or the "R" coating to be applied on the opposite side of the backside-coated and back-grey coated side, as mentioned above.

In other words, the white coating and the gray coating on the back, and then the "S" coating or the "R" coating on the back, so that the back coating liquids, which have been processed previously, are the fabric to be coated with the current "S" coating or the "R" coating. It is not easy to carry out this process because it does not adhere to the surface of. This can be expected to some extent by the processing method mentioned in the above-mentioned boiling process.

First, first coat, then dry, and then cool. And after the second coating again dry.

In particular, this not only allows the coating solution to penetrate the fabric evenly, but also separates the individual coating layers, compared to combining all the coatings in one go. Tea coating liquid acts as an intermediate to fix the fabric so that it does not easily fall off the fabric. And it is easy to prevent the discoloration of the fabric surface coating easily in the penetration of water.

Secondary coating evenly absorbs ink and helps to express colors realistically.

In particular, since the secondary coating proceeds in the cooled state after drying the primary coating, the coating liquid is solidified just before being uniformly distributed on the fabric during the second coating due to the heat penetrating into the fabric at the time of the first coating and coated on the fabric in the form of a lump. It can be prevented in advance, and it is possible to minimize the phenomenon that the coating line on the fabric surface during coating. This is to prevent the transmission of light by maintaining a separate coating layer, rather than combining all coatings at once, to maximize the effect of the respective coating liquids.

In addition, the secondary coating solution is to be strongly fixed on the primary coating solution.

In applying “S” coating and “R” coating, do the following:

<“S” 1st Coating>

65-inch wide, 62g to 69g per yard and 1.5mm knife for coating. When drying the coating liquid, the room temperature of the drying chamber is maintained at 170 ~ 190 ℃.

The surface tension of the fabric is maintained at a relatively loose state to allow the coating liquid to be sufficiently applied by the knife spacing of 1.5 mm. If the surface tension is maintained too strong, the coating liquid may be applied too thin and the fabric may be reduced again after the completion of the product. do. This is to prevent tunneling after lamination of fabric and Becker.

<“S” 2nd Coating>

It is 65g wide and 34g ~ 41g is used for one yard and 2mm knife is used for coating. When drying the coating liquid, the room temperature of the drying chamber is maintained at 170 ~ 190 ℃. The surface tension of the fabric is maintained at a relatively loose state so that the coating liquid is sufficiently applied by the knife interval of 2 mm. The reason is as described above in the first coating.

<“R” 1st Coating>

It is 65 inches wide and 62g ~ 69g is used in one yard. When coating, knife interval is 1.5mm. When drying the coating liquid, the room temperature of the drying chamber is maintained at 165 ℃ ~ 180 ℃. The surface tension of the fabric is maintained at a relatively loose state so that the coating liquid is sufficiently applied by the knife spacing 1.5 mm.

<“R” 2nd coating>

It is 65 inches wide and 62g ~ 69g is used in one yard, and the thickness of knife when coating is 2mm. When drying the coating liquid, the room temperature of the drying chamber is maintained at 165 ℃ ~ 180 ℃. The surface tension of the fabric is maintained at a relatively loose state so that the coating liquid is sufficiently applied by the knife interval of 2 mm.

After the "S" coating or "R" coating process as above must be aged in natural state for 3 to 4 days.

This is to prevent the curling of the fabric and the tunneling phenomenon between the fabric and the Fuji, since the fabric is reduced on the Fuji after completing the lamination of the fabric and the Becker.

Because the fabrics absorb different amounts of water, curling and tunneling occur when they come in contact with paper. In this way, it is possible to give enough time while ripening in the natural state to prevent the product from shrinking after the completion of the product lamination.

5. The following process relates to laminating and other processes of fabrics and beakers.

The lamination machine type is comma-cotta type.

Fuji (Becker) chooses about 100g of white imitation paper. This is most suitable for the environment in which the fabric of the above process is pursued, so that the speed of sucking and spitting moisture is similar to that of the surface fabric. In addition, over time, both the fabric and the Fuji show a slight decrease. In order to keep the reduced radius widths similar to each other, a thickness of 100 g of white imitation paper is selected.

Alternatively, PET fuji may be used, but it is advantageous to select a thickness of 100 g of white imitation paper, and the fuji made of imitation paper is not uniform and the height is not flat on the surface. The surface is not in contact with the adhesive portion that is configured with the surface fabric of the present invention, and when the surface fabric is removed from the Fuji for later use, there is an advantage that the surface fabric and the Fuji more easily separated.

PET Fuji is smoother and flatter than 100g white imitation paper. And although the surface is constant, the breathability is remarkably deteriorated due to such a part, so that it is difficult to detach easily when the surface fabric is removed from Fuji for use in contact with the adhesive part constituted with the surface fabric of the present invention.

The basic active ingredient of the removable adhesive is as follows.

INGREDIENTS CAS NO Weight (%) Acrylic Polymer - 31-35 Ethyl acetate 147 -78 -6 35-45 Toluene 108 -88 -3 10-20

The ratio of the synthetic solvent and the curing agent is 100 g of the synthetic solvent so that the curing agent is 2 g so that the sum is 102 g. This is an ideal ratio of keeping the adhesive strength strong and easy to remove.

After mixing the synthetic solvent and the curing agent for about 30 minutes, the adhesive is evenly applied on the beaker, wherein the adhesive thickness is 1.8 microns to 2.0 microns is the best thickness for the surface fabric of the present invention.

Because the polyester DTY (Draw Textured Yarn) itself absorbs some of the adhesive when it is laminated, if you keep a rather thick coating on top of the beaker later, after the adhesive has been partially vaporized and dried through a heat dryer, A suitable amount of adhesive remains.

After the adhesive coated Fuji passes through the drying chamber, it is pressed through the rollers to make contact with the surface fabric to complete the lamination. The most important thing is that the backside gray coating, which is the opposite side of the fabric already surface-coated, is treated. The surface should be brought into contact with the adhesive coated beaker (fuji) to complete the lamination.

The reason is that in the present invention, the removable adhesive must be coated with the adhesive on the backside-treated surface, which is the back side of the surface-coated fabric.

When the products are laminated and finished, they are subjected to various cuttings (roll foundation, re-milling) after a aging period at room temperature of about 50 ℃ for one day.In this case, the products must be rolled again in the opposite direction. Start cutting 3-4 hours after rolling. This is to keep the finished product's flatness (the force to stay flat) by winding the fabric and the Becker wound in one direction again in the opposite direction.

The fiber-adhesive paper completed by the present invention is boiled and quenched the fabric woven with Polyester DTY (Draw Textured Yarn) yarn is the width of the fabric shrinkage of 10% to 15%.

In addition, the back of the fabric (1) is a mixture of polyurethane resin and white pigments in a ratio of 6 to 4, respectively, and the rear white coating layer 11 coated twice is composed of polyurethane resin and gray pigments in a ratio of 6 to 4, respectively. The back gray coating layer 12 is mixed and coated once, and the first S coating layer 21 coated with a primary S coating liquid containing 40 to 50% by weight of ethylene vinyl acetate copolymer. Then, the second S coating layer 22 was coated with a second S coating solution containing 25 wt% of polyurethane synthetic resin (Poly urethane Resin).

Alternatively, in place of the primary S coating layer 21 and the secondary S coating layer 22, an R coating liquid containing 60 to 75 wt% of low molecular alcohol and 8 to 12 wt% of silicon dioxide. Using R to form a coating layer 23 coated two times in the first and second, and the adhesive 30 is coated on the back Fuji 30 is in a state of lamination.
