Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for making temporary flocking by applying an adhesive to a base material conventionally used as a transfer sheet, such as cloth, nonwoven fabric, cellophane, synthetic resin film, parchment paper, or kraft paper. A flocked base is formed by forming an adhesive layer, and then planting short fibers, glass fine particles, and metal fine particles (in many cases, ultra-fine short fibers are used, so these are hereinafter referred to as flocking materials) at high density. flocking, in which the entire surface is colored or printed with a pattern or design by means such as screen printing, and then a thermocompression-adhesive synthetic resin layer is formed on the colored entire surface or the printed surface of the pattern. The present invention relates to a flocked base used for the patch material of the method and a method for manufacturing this flocked base.

Next, the general structure and usage examples of the flocking and transplanting patch material will be explained.

The structure of the patch material using the flocking and transplanting method is to form a temporary planting layer of flocking material on the base, to which flocking material such as short fibers is flocked to form a flocking base, and the flocking base is colored or patterned. The flocked flocks are colored by printing a pattern, and a thermocompression synthetic resin layer (resin adhesive that melts when heated) is applied to the printed surface, that is, the head of the colored flocked sections by printing.
It is formed by forming.

Next, an example of the use of the patch material will be described. First, the thermocompression adhesive synthetic resin layer of the patch material is placed on the surface of a shirt or the like, and then pressed with a heating tool such as an iron.

Then, the thermocompression-adhesive synthetic resin that forms the thermocompression-adhesive synthetic resin layer melts and penetrates into the weave of the fabric of the shirt, etc. At the same time, the head of the flocked patch material is also immersed in the melted resin. become a state.

When the molten resin cools, the flocked patches of the patch material are solidified and fixed to the surface of the shirt or the like in the above-described state as the molten resin cools.

Next, when the patch material is peeled off from a shirt, etc., the part where the thermocompression bondable synthetic resin layer is not formed will remain as is, and the part where the thermocompression bondability synthetic resin layer has been formed will be grafted onto the shirt, etc. as described above. It is fixed to the surface and transferred, while the base of the implanted flock is peeled off from the base temporary adhesive.

As a result, flocking is carried out on the surface of the shirt or the like in the same pattern as that on which the thermocompression bondable synthetic resin layer is formed.

In order to produce the flocked base of this flocked flocking method patch material, the conventional flocking technology concept is adopted as is, temporary adhesive is applied to the base to form a temporary adhesive layer, and this surface is electrostatically charged. A method has been adopted in which a flocking treatment is performed to implant a flocking material, and then this is dried to fix the flocking material to a base on which a temporary adhesive layer is formed.

However, the flocked base produced by such a conventional method has at least the following two undesirable phenomena.

The first phenomenon is that, as shown in the cross-sectional view of the flocked base 4 shown in FIG. Some are planted vertically, some are planted at an angle, and some are planted on their sides.

This phenomenon occurs when the temporary adhesive of the temporary adhesive layer 2 formed on the base 1 is applied and the flocking work is carried out while it is still in paste form, and while it is being transferred to the drying process, the flocking is done. As a result of experiments, it was found that this is because the flocked hair 3 is tilted or laid down on its side, dried in this state, and stuck to the temporary adhesive layer 2 of the base 1 as it is.

The second phenomenon is clearly seen in FIG. 2, which shows a cross-section of the flocked base 4 on a larger scale than in FIG. 1. The proximal end portion 3a of the hair flock 3 is deeply implanted into the condensed temporary adhesive layer 2, and the root 3b of the flocked hair 3 is also covered with the condensed temporary adhesive layer.

This is because the flocking work is performed while the temporary adhesive layer 2 formed on the base 1 is still in a loose paste state, so the base end 3a of the flocking 3 is inside the temporary adhesive layer 2. This is because the temporary adhesive forming the temporary adhesive layer 2 rises to the root 3b of the implanted hair to a certain extent due to capillary action, and as a result, a capillary curtain is created at the root 3b of the hair transplant 3. Since the drying process is carried out in this state, the above-mentioned phenomenon occurs.

Therefore, when a patch material of the flocking method in which a heat-pressure adhesive synthetic resin layer 9 is formed on a flocking base 4 made by a conventional method is carried out on a fabric surface 10 of a shirt or the like using the above-mentioned method, the following results can be obtained. There are at least three drawbacks as listed below.

That is, the first drawback is that even if the thermocompression adhesive synthetic resin layer 9 is formed on the four sides of the flocked base 4, the heights of the flocked flocks 3 planted on the flocked base 4 are uneven, which causes the phenomenon mentioned above. ,
The four sides of the flocked base will not be formed at the same height, and this means that among the flocked flocks 3, the ends of the flocked heads will not reach the thermocompression adhesive synthetic resin layer 9.

(See Figures 1 and 2) Therefore, when performing the above-mentioned flocking and transplanting work using such a patch material, the resin of the thermocompression-adhesive synthetic resin layer 9 is melted and melted onto the cloth surface 10 of a shirt or the like. Even if a resin penetration part is formed, the head end of the flock 3 planted in the flock base 4 up to this part does not reach the molten resin penetration part, and as a result, the flock is not transferred to a shirt, etc. Therefore, extremely sparse flocking is carried out on the cloth surface 10 of a shirt or the like, resulting in the disadvantage that an inappropriate shape of flocking is formed (Fig. 3). The disadvantage is that due to the second phenomenon, when coloring, patterns, or designs are printed on the flocked base 4 by a method such as screen printing, the base end 3a of the flocked flock 3 planted on the flocked base 4 is condensed. The printing ink is embedded deeply into the temporary adhesive layer 2, and the roots 3b of the flocked flocks 3 are covered with the condensed temporary adhesive, so that the printing ink is embedded deeply into the flocked flocks 3.
This has the drawback that it does not penetrate sufficiently to the proximal end 3a or the root 3b of the flocked hair 3, and thus the hair flocked 3 cannot be colored as desired. When the above-mentioned flocking and transplanting work is performed using a patch material using the flocking and transplanting method, there is a drawback that flocks with uneven coloring are transferred to the cloth surface 10 of a shirt or the like.

The third drawback is that, in general, the flocking and transplanting work of patch materials using the flocking method is performed as described above, so that among the flocks 3 planted on the flocking base 4, after the above-mentioned transplanting work is performed. The flock 3 to be transplanted must be immediately peeled off from the flock base 4.

However, the flocked hairs 3 planted on the flocked base 4 which caused the phenomenon mentioned above are either deeply implanted in the temporary adhesive layer 2 where the base end 3a is set or the roots 3b of the flocked hairs 3 are Because it is planted while being covered and fixed with a temporary adhesive that has set,
In order to perform the above-mentioned flocking and transplanting work, etc., the flocking material is torn off from the fabric surface of a shirt, etc. The flocking 3 is implanted in the flocking base 4, and one side of the flocking 3 is attached to the setting temporary adhesive layer 2 of the flocking base 4. The other side is fixed to the thermocompression adhesive synthetic resin that has been melted and condensed on the fabric surface 10 of the shirt, etc., so the flocked hair 3 is not torn off from the middle or not transferred when it is peeled off, and the flocked base 4 is If the fibers remain stuck to the fibers and are pulled out, sparse transfer may occur on the cloth surface 10 of a shirt or the like, or pieces of the temporary adhesive layer of the flocked base 4 may adhere to the flocked base end 3a. ＼This has the disadvantage of being transferred to shirts, etc.

The present invention solves the problems caused by these conventional techniques.

That is, an object of the present invention is to obtain a flocked base in which the flocked hairs are implanted at a high density and all the flocked hairs are planted in a manner that they stand upright with respect to the base.

Another object of the present invention is to obtain a hair transplant base that can be completely colored up to the proximal end of the hair transplanted on the hair transplant base.

Furthermore, it is an object of the present invention to create a patch material using a flocking and transplanting method, which can completely transfer the middle of the flocked hairs planted on the flocking base.

Another feature of the present invention is that a flocked flocked shape with a good finish can be formed on a shirt or the like using a flocked flocked patch material using the above-mentioned flocked base.

In order to solve the problems of the prior art, it is necessary to completely change the conventional technical idea of performing electrostatic flocking immediately after applying a temporary adhesive to the base to form a temporary adhesive layer.

In other words, even if the temporary adhesive traditionally used for hair transplantation is applied to the base to form a temporary adhesive layer, it remains in a loose paste-like state for a while, so during this time, If this work is carried out, the phenomenon described above such as the flocking falling sideways or planting deeply will occur, and if the base is left with temporary adhesive applied, the board adhesive will dry and the flocking will not be possible. This means that the hair transplant operation cannot be carried out because the hair loses its ability to plant hair.

Therefore, the present invention was completed based on the idea that it is necessary to improve the procedure for creating a hair transplant base and to use a completely different hair transplant agent to be applied to the base.

Hair transplanting agents that can be used in the examples of the present invention include natural rubber, synthetic rubber, acrylic acid copolymer, polyethylene oxide, vinyl methyl ether and maleic anhydride copolymer, vinyl acetate, and others with the same effect. Possible adhesives include:

These adhesives still have adhesive strength to adhere objects even after being applied to various bases and dried.

A good example of this is the adhesive used in cellophane tape.

An embodiment of the present invention will be described below with reference to the drawings.

In the present invention, any one of the various adhesives described above is used as a base 5.
Firstly, it is dried by an appropriate means, and then the base 5 is applied.
An adhesive layer 6 is formed integrally with the adhesive layer 6.

(See Figure 4) Although the adhesive layer 6 formed on the base 5 through this operation is no longer in the liquid state at the time of adhesive application, the adhesive layer 6 whose adhesive strength has not yet deteriorated remains on the base 5. is formed.

After the adhesive layer 6 is formed on the base 5, the base 5 is passed through an electrostatic flocking device to perform electrostatic flocking.

Through this operation, the flocked material is charged with static electrons, and the base 5 on which the adhesive layer 6 described above is formed is placed on the electrode side, so that the flocked material is perpendicular to the base 5 on which the adhesive layer 6 is formed. rush to.

Therefore, the flocked hair 7 is planted upright on the adhesive layer 6 formed on the base 5.

(See Figure 4) At this time, since the adhesive layer 6 formed on the base 5 is no longer in a liquid state, the base end of the flocked hair 7 to be implanted is deeply pushed into the adhesive layer 6. It can be planted at a shallow depth without any disturbance.

In addition, the adhesive constituting the adhesive layer 6 does not cause capillary action to the planted hair flocks T, and does not cover the roots of the planted hair flocks 7.

In other words, the flocked base 8 obtained as a result of this flocking operation is such that the surface of the adhesive layer 6 formed on the base 5 is hardened to some extent, as shown in FIG. The flocked flocks 7 exhibit the phenomenon inherent to electrostatic flocking and are planted at right angles to the surface of the adhesive layer 6 and at a shallow depth. Capillary action of the adhesive constituting the adhesive layer 6 does not occur in the installed flocks 7, so the roots of the implanted flocks 7 are not covered with adhesive, and the adhesive is not dried. Since the hairs are implanted not in a liquid state but in a somewhat hardened state, there is no possibility that the implanted hairs 7 will fall laterally.

The adhesive layer 6 is made of an adhesive formulated to maintain a certain level of viscosity for a considerable period of time.
is not fixed to the adhesive layer 6, and can maintain a so-called temporarily fixed state.

The aspect of this flocked base 8 is greatly different from the aspect of the conventional flocked base 4 shown in FIG.

An example of an experiment conducted to obtain such a hair-planted base 8 will be given.

As an adhesive, I chose EXP70J made by Dainippon Ink, which is an acrylic acid copolymer, and used synthetic paper (pulp 50:
This was spread on PP50) to form an adhesive layer 6, and a temporary flocking experiment was carried out in which 3D of rayon pile, 0.5 mm thick, was temporarily planted in the following manner.

First, an adhesive is applied onto synthetic paper at a rate of 20 to 30 g/rrl', and the surface is dried by heating at a temperature of 80° C. for 30 seconds to 1 minute.

The rayon pile is then flocked in an electrostatic field of 20,000 volts.

As a result of this experiment, all the flocked hairs 7 were planted at a high density as shown in FIG. It was possible to obtain an extremely excellent hair transplantation base 8 that met the conditions.

This flocked base 8 is colored or printed with a pattern or design by the same method as before, and then the entire area of the flocked surface of the flocked base 8, that is, the tip of the flocked flock 7, or the pattern or design is printed. By performing a process to form a thermocompression-adhesive synthetic resin layer 9 covering the area of the printed surface, it was possible to create a flocking-transplanting patch material.

The flocked flocks 7 planted on the flocked base 8 are planted almost upright with respect to the adhesive layer 6 formed on the base 5, so the height of the flocked flocks 7 is approximately constant. Since the fibers were erected, the thermocompression bondable synthetic resin layer 9 formed on the surface of the flocked base 8 could be formed to evenly cover the tips of the flocked flocks 7.

(Refer to Fig. 4) Therefore, this flocked base 8 is used to make a patch material for the flocked transplant method, and this is used to form a desired flocked shape on the cloth surface 10 of a shirt or the like using the above-described work. Since the tips of the flocked flocks 7 are evenly immersed in the molten thermocompression adhesive resin on the fabric surface 10 of the shirt, etc., the phenomenon mentioned as the first drawback of conventional patch materials does not occur, and the flocks are evenly distributed. Hair transplantation was performed.

In addition, the implanted flocks 7 planted in the flock base 8 are attached to the base 5.
The hair is implanted with only its base end remaining in the adhesive layer 6 formed on the adhesive layer 6, and the adhesive does not cover the roots of the implanted hair 7, so the hair transplant base 8 colored,
When printing patterns or designs, the printing ink can also penetrate into the roots and proximal ends of the flocked flocks 7, making it possible to print with a good finish.

Therefore, this flocked base 8 is used to make a patch material for the flocked transplant method, and this is used to form the desired flocked shape on the cloth surface 10 of a shirt or the like in the above-described operation. Since the printing was done with a good finish, it was possible to perform flocking with a good colored finish, which eliminated the second drawback when using conventional patch materials.

In addition, the flocked flocks 7 of the flocking material of the flocking transfer method using this flocking base 8 are implanted very shallowly on the adhesive layer 6 formed on the base 5, so the flocking experiment described above was carried out using this patch material. When this was done, a transplanted flocked shape was formed on the cloth surface 10 of a shirt or the like, which eliminated the third drawback when using conventional patch materials.

(See Figure 5) As explained above, according to the present invention, most of the flocked hairs are planted upright on the base, and are also planted very shallowly on the adhesive layer formed on the base. A flocked base can be obtained, and the flocked base is colored, printed with patterns, and designs, and a thermocompression-adhesive synthetic resin layer is formed on the entire printed surface or in a desired shape, thereby making it possible to use the flocking and transplanting method. When a patch material is made and used to transplant hair onto a cloth surface such as a shirt, an ideal shape of the hair transplantation can be formed on the cloth surface such as a shirt.
