BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hologram fabric,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hologram fabric and a method of manufacturing the hologram fabric, and more particularly, to a hologram fabric that is environmentally friendly and durable by implementing a hologram using a water-based resin on a fabric.

Generally, fabrics made of chemical fibers such as nylon or polyester are printed with silkscreen printing. Silkscreen printing is not only monotonous but also difficult to implement various effects.

According to this trend, new printing methods that can embody patterns on a fabric have recently been spotlighted. Of these, holograms are media in which interference fringes reproducing stereoscopic images are recorded. Patterns and shapes are changed by interference phenomenon depending on the direction of light To be printed.

For example, a holographic film to which a hologram is applied is used not only for banknotes, merchandise, and credit cards for judging authenticity, but also as an interior effect as a building interior material and as a packaging material.

However, since the hologram film can obtain a pattern and a shape by reflection of light, when the shape of the film is deformed, there is a problem that a proper hologram can not be realized on the fabric.

In addition, since the surface of the fabric itself is not smooth, the hologram film is not stably bonded to the surface of the fabric, and the hologram film is bonded to the fabric by an adhesive only. There is a problem that the durability is poor.

Therefore, there is a desperate need to study the development of a new technology for fabric that can improve the durability by stably implementing the hologram.

Korean Patent Laid-Open Publication No. 10-2004-0037291, 2004.05.07.

The hologram fabric according to the present invention for achieving the above object is manufactured by the manufacturing method described above.

According to the present invention, the hologram is formed stably on the release paper after the water-based resin and the binder are sequentially formed on the release paper on which the hologram pattern is formed, and then thermally transferred to the fabric, thereby producing a hologram fabric having improved durability There is an effect that can be.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flow chart according to a preferred embodiment of the present invention, and FIG. 2 is a flow chart of FIG.

1 and 2, the hologram material of the present invention includes a first step (S10) of forming a first holographic pattern P1 on the release layer 100, a first holographic pattern P1 A third step S30 of forming a binder layer 300 on the upper side of the hydrophilic resin layer 200, a third step S30 of forming a binder layer 300 on the upper side of the hydrophobic resin layer 200, A fourth step (S40) of thermally transferring the release layer (100) having the water layer (200) and the binder layer (300) formed thereon to the circular layer (400) and separating the release layer (100) from the circular layer And a fifth step S50 of implementing a second holographic pattern P2 corresponding to the first holographic pattern P1 on the original layer 400. [

First, a first step is a step of forming a first holographic pattern P1 on the release layer 100. (S10)

Prior to this, a hologram film having a hologram implemented in the past was directly adhered directly to a fabric by an adhesive. When the hologram film is directly adhered to the fabric, the hologram film peels or wrinkles from the fabric over time There is a problem in that it is not durable.

In order to solve such a problem, in the present invention, a first holographic pattern P1 is formed on a release layer 100 made of polyethylene terephthalate (PET), and then a hydrophilic layer (not shown) is formed on the release layer 100 200 and the binder layer 300 are sequentially formed and then the second holographic pattern P2 corresponding to the first thermal transfer hologram pattern P1 is formed on the far-end layer 400, the durability And to improve the durability of the fabric at the same time.

As a method for forming the first holographic pattern P1 on the release layer 100, a roll mold or a laser molding is used. In the roll mold formation, the release layer 100 passes through a roll mold having a pattern formed therein The first holographic pattern P1 is molded, and laser molding is a method that has been used in recent years in a relatively inexpensive alternative method instead of an expensive roll mold.

However, the first holographic pattern P1 in the present invention may be formed by any of a roll mold or a laser mold.

Next, in the second step, the hydrophilic resin layer 200 is formed on the release layer 100 on which the first hologram pattern P1 is formed. (S20)

The aqueous resin layer 200 is formed by printing an aqueous resin on the upper surface of the release layer 100 on which the first holographic pattern P1 is formed as described in the first step. The first hologram pattern P1 as the basis of the second hologram pattern P2 implemented in the first hologram pattern 400 can be printed.

In other words, the reason why the hydrophilic resin layer 200 is formed in the second step is that when the hologram film (for example, transfer paper) on which the conventional hologram is implemented is directly adhered to the fabric by hot melts, So that the holographic film is wrinkled or the entire holographic film is peeled off, which is not only ineffective but also has a problem of poor durability.

In other words, the release layer 100 on which the first holographic pattern P1 is formed is formed by printing a water-based resin on the top of the release layer 100 on which the first holographic pattern P1 is formed while passing through the roll type flat panel automatic screen The hydrophilic resin layer 200 can be formed.

At this time, the hydrophilic resin layer 200 is applied (or printed) to the top of the release layer 100 on which the first holographic pattern P1 is formed while passing through the roll type flat panel automatic screen, The process of redispersion (or re-printing) of the hydrophilic resin layer 200 on the release layer 100 and drying after passing through the roll type flat panel automatic screen may be repeatedly performed a plurality of times.

The reason for performing the drying process after the formation of the hydrophilic resin layer 200 a plurality of times is that the hydrophilic resin layer 200 is formed one time Because the color is too soft after printing, it is not easy to express the desired color with only one printing.

If the thickness of the final target of the desired water repellent layer 200 is 200 μm, if the water-based resin is first printed at a thickness of 200 μm and then dried, the water repellent layer 200 is reduced to 100 μm. If the water-based resin is further printed to a thickness of 200 μm, the thickness of the water-repellent layer 200 is reduced to 300 μm, but the water-repellent layer 200 having a thickness of 200 μm is obtained . Through this process, the water-based resin layer 200 can be freely expressed in a desired color.

However, the process of printing and drying may be repeated 2 or 3 times in some cases, but the number of times can be variously changed for the demand of the customer or the desired color.

Particularly, the reason why the water-based resin is applied to the water-repellent layer 200 in the present invention is that the oily water such as commonly used dimethylformamide (DMF) and methyl ethyl ketone (MEK) is harmful to the human body, And that the water-based resin itself is eco-friendly.

Since the water-based resin layer 200 is a water-based resin mixed with resin solids and water at a weight ratio of 1: 1, if the water-based resin layer 200 is not dried due to the presence of water, 200) flow down and the implementation of the second hologram pattern P2 is not performed neatly, so that the drying process must be performed.

If the resin solids and water are not mixed at a ratio of 1: 1 (i.e., 50 wt% of the resin solid content and 50 wt% of the water) and the amount of water is relatively larger than the amount of the resin solid content, It is preferable that the water-based resin is composed of a resin solids content and water at a mixing ratio of 1: 1, since it is difficult to smoothly express the color.

In this case, the resin solid component of the water-based resin can be selectively used either as a polyurethane resin or an acrylic resin, and they can be used by mixing them. However, the present invention is not limited to such a type and can function as an environment- Any resin solid matter may be applied.

Next, the third step is a step of forming the binder layer 300 on the hydrophilic resin layer 200. (S30)

That is, the binder layer 300 is formed on the upper portion corresponding to the shape of the hydrophilic resin layer 200 for bonding between the hydrophilic resin layer 200 and the clay layer 400, and the binder layer 300 is a binder But the present invention is not limited thereto. Any binder may be used as long as it can adhere the aqueous resin layer 200 and the artificial layer 400 to each other.

In the third step, similarly to the second step, the binder layer 300 is formed by applying or printing a binder corresponding to the upper portion of the water-based resin layer 200 using the roll type flat panel automatic screen, and then dried can do.

This is to improve the adhesive force between the water-based resin layer 200 and the far-end layer 400. After the binder layer 300 is formed, the drying process can be repeatedly performed 3 to 6 times. However, It is not just that.

In addition, it is desirable for the binder layer 300 to have a melting temperature of 80 to 180 ° C. If the melting temperature is lower than 80 ° C., the adhesive strength between the water-absorbent resin layer 200 and the far- And if it has a melting temperature exceeding 180 ° C, it must be heated to a high temperature in order to impart adhesiveness between the water-absorbent resin layer 200 and the artificial layer 400 Therefore, the binder layer 300 may protrude outward and remain sticky, which makes it difficult to implement the hologram on the art layer 400 neatly. Therefore, it is preferable that the material forming the binder layer 300 has a melting temperature range of 80 to 180 ° C.

Accordingly, the aqueous resin layer 200 can be attached to the artificial layer 400 with the binder layer 300 as a center, thereby facilitating mass production of the hologram-embodied fabric.

Next, the fourth step is a step of thermally transferring the adhesive layer 100 formed with the water-absorbing resin layer 200 and the binder layer 300 to the art layer 400 in close contact with each other. (S40)

That is, the fourth step is to adhere the release layer 100 having the water-based resin layer 200 and the binder layer 300 on the surface of the artificial layer 400 and to form the release layer 100 through the water- The first holographic pattern P1 may be thermally transferred to the far-end layer 400 using a thermal transfer press or a pair of heating / pressure rolls.

In the state where the release layer 100 on which the hydrophilic resin layer 200 and the binder layer 300 are formed is placed on the worktable 400 on the worktable (the farthest layer 400 and the binder layer 300 are in contact with each other) A thermal transfer process is carried out while passing through a thermal transfer press or a pair of heating / pressure rolls to form an image of the first hologram pattern P1 formed on the release layer 100 in the outer layer 400 2 hologram pattern P2 is transferred.

Finally, the fifth step is a step of separating the release layer 100 from the far-end layer 400 to implement the second holographic pattern P2 corresponding to the first holographic pattern P1 on the far-end layer 400. FIG. (S50)

That is, the fifth step is a step for finishing the present invention, and is a step for finally embodying a hologram on a desired fabric.

The hydrophilic resin layer 200 embodying the first holographic pattern P1 formed in the release layer 100 is adhered to the artificial layer 400 by the binder layer 300 and after the thermal transfer is completed, The adhesive layer 300 and the artificial layer 400 are adhered to each other with respect to the first holographic pattern P1 and the adhesive layer 300 is separated from the adhesive layer 100. Finally, The second holographic pattern P2 of FIG.

The second holographic pattern P2 in the fifth step is formed on the surface of the hydrophilic resin layer 200 adhered to the artificial layer 400 by the binder layer 300. As described above, the hologram film having the hologram implemented in the past is directly adhered to the fabric by the adhesive (or hot melt). In this case, as the use period of the fabric becomes longer, not only the implemented hologram is weakened but also the hologram film itself Most of it was peeled off, so the fabric was not durable.

However, in the present invention, the first holographic pattern (P1) is transferred to the durable resin layer (200) through a releasing paper, rather than the holographic film itself, so that the first holographic pattern (P2) corresponding to the first hologram pattern (P1).

The hologram is clearly realized on the surface of the hydrophilic resin layer 200 adhered to the clay layer 400 by the binder layer 300 so that the hydrophilic resin layer 200 is peeled off or peeled off from the clay layer 400 The durability of the hologram fabric can be achieved.

3 is a photograph according to a preferred embodiment of the present invention. Referring to FIG. 3, it can be seen that the second holographic pattern P2 corresponding to the first holographic pattern P1 is implemented on the upper side of the far-field layer 400. FIG.

Since the refraction of light differs according to various angles, various shapes and patterns can be seen to achieve a variety of designs, and since the hologram film itself is not adhered to the fabric by an adhesive, The second holographic pattern P2 is implemented on the first holographic pattern 200 so that the second holographic pattern P2 does not fall off from the first holographic layer 400 and the durability of the hologram fabric can be achieved.

However, the fabric referred to in the present invention may be selectively used from the group consisting of cloth, fabric, leather, and synthetic resin, but it is not necessarily limited to this kind but various fabrics are applicable.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention may be embodied otherwise without departing from the spirit and scope of the invention.
