Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric flocking method, and in particular is a method that enables multicolored flocking with clear border lines.

Even in the conventional electric flocking process, various types of multi-colored flocking are carried out. There was a problem that hair transplantation was not possible.

Conventional multicolor hair transplantation is mainly done by multicolor print hair transplantation, but this multicolor print hair transplantation involves pre-drying (drying at room temperature) after transplanting one color print hair, and then transplanting piles of different hues. In this method, the hair is transplanted sequentially starting from the light color, and finally a colored pile is transplanted.However, because pre-drying is required for each color, the flocking efficiency for multicolors is extremely poor, and the difference between colors is high. It also has the disadvantage that the boundaries are very unclear. Furthermore, in order to eliminate this drawback, the present inventor has proposed a multicolor flocking method for flocking mats displaying color-coded patterns in the 1975 Shin Utility Model Registration Iso No. 9423.

However, when this method is used, the flocking efficiency is improved compared to the multicolor print flocking method, and it is also possible to make the boundaries between colors clearer to some extent, but it does not produce very crowded and complex patterns or figures. It was difficult to express In other words, this method involves applying an adhesive to the surface of the material, directly covering a part of it with a mask and planting piles, then removing this mask and planting piles of different colors on the parts that were covered by the mask. Multi-colored hair transplantation is performed using this method, but it is necessary to provide a gap between the mask and the material surface so that the mask does not come into contact with the adhesive-applied area. The countless piles that fly up collide with the green edge of the mask, and the piles that do not fly up perpendicular to the material surface due to dew hot water etc. enter through the gap covered by the mask and are flocked, so the piles of different colors are the border. Because the hair is planted in lines, the boundaries between colors become unclear.

In addition, in order to prevent this drawback, if the gap between the mask and the material surface is made extremely small, the mask will come into contact with the adhesive-applied part of the material surface during the flocking process, and the mask itself will be glued to the surface, making it impossible to remove it or forcing it off. There were problems such as parts of the mask being glued as they were, resulting in a loss of product value, or the adhesive on the mask adhering to other flocked parts.

The object of the present invention is to provide an electro-flocking method that solves these conventional technical problems.

The electric flocking method of the present invention involves planting piles in a sparse manner on a surface to be flocked to form a sparse flocking surface, and then covering a part of the sparse flocking surface with a hair flocking prevention mask of an arbitrary shape to form a colored pile. is transplanted onto the sparse flocked surface, then the flocking prevention mask is removed and the area where colored piles are flocked is covered with a flocking prevention mask.
The feature is that colored piles of different colors are implanted on the sparsely implanted surface.

Next, the present invention will be explained based on drawings showing one embodiment thereof.

Reference numeral 1 denotes a material to be flocked, and an adhesive 2 is applied to the entire surface or a part of the surface thereof to provide a flocked surface 3.

The flocking material 1 may be any material capable of flocking, regardless of whether it is a woven fabric or a nonwoven fabric, and may also be a so-called flocked material having flocks on a base fabric. The adhesive 2 may be any ordinary adhesive for flocking, and an emulsion type acrylic resin adhesive is preferred because of its flocking strength and ease of handling.

The adhesive is applied to the entire surface or a part of the flocked material 1.

The adhesive 2 is applied to the flocked material 1 on the entire surface or a part of the flocked material 1 in the form of arbitrary letters, figures, or pictures, as necessary, to form the flocked surface 3.

In this way, the piles 4 are sparsely planted on the flocked surface 3 formed on the flocked material 1 to form a sparse flocked surface 5.

The pile 4 can be of any length that allows electro-flocking, but a length of about 1 to 5 ribs is preferred, and synthetic fibers such as rayon and nylon, or natural fibers are used. In this case, if the pile 4 is made of a transparent or translucent material, there will be no mixing of colors when colored piles are implanted, and the boundaries of the color-coded pattern will become clearer. The flocking of the piles 4 on the flocking surface 3 is carried out in a sparse manner, that is, as long as it is possible to support the hair flocking prevention mask.

Next, a part of the sparse flocked surface 5 formed on the flocked surface 3 is covered with a flocked prevention mask 6 formed in an arbitrary shape of letters or pictures.

Sparse flocked surface 5 not covered by flocking prevention mask 6
After the colored pile 7 is transplanted to a predetermined density, the hair transplant prevention mask 6 is removed from the sparse flocked surface 5, and the colored pile 7 is
The part where the hair has been transplanted is covered with a hair transplant prevention mask 6, and the colored pile 8 having a different color from the colored pile 7 is implanted in the part where the colored pile 7 of the sparse hair-planted surface 5 is not transplanted.

The anti-flocking mask 6 may be made of paper, synthetic resin, or the like, but paper or hard plastic may be used because it is lightweight and has a certain degree of hardness so that it can be sufficiently supported by the piles 4 of the sparse flocked surface 5. A plate is preferred.

The anti-hair transplantation mask 6 has the effect that if the clips 9 are provided in a protruding manner, it will be extremely convenient to remove and attach the clips.

The colored piles 7 and 8 may be natural woven fibers or synthetic woven fabrics, but they may be of any chromatic color other than transparent, and usually piles dyed to a desired hue are used.

The thickness of the colored piles 7 and 8 does not matter, but the length thereof needs to be the same as or longer than the pile 4 that is flocked on the sparse flocked surface 5.

Since the pile 4 and the colored piles 7 and 8 have the same length in this way, the gap between the hair transplantation surface 3 and the hair transplantation prevention mask 6 is the same as the length of the colored piles 7 and 8. Since there is no fear that the colored piles 7 and 8 will be mixed into the part covered by the hair transplant prevention mask 6 and transplanted, there is an effect that the boundary line where the hair is transplanted in a color-coded pattern becomes clear.

The pile lengths of the colored piles 7 and 8 are made equal to or longer than the length of the pile 4, and the wisteria-like flocked surface 5 on which the piles 4 are loosely flocked is partially covered with a flocking prevention mask 6. Therefore, the colored piles 7 and 8 will never invade the inside of the area covered by the hair transplant prevention mask 6 and will be implanted, so the border where the hair is implanted in the color-coded pattern will be extremely clear, and therefore it will not be possible to avoid complicated characters, figures, etc. Not only can the pattern be easily flocked, but since all the piles are vertically flocked, high flocking strength can be obtained. 4 to 6 show other embodiments of the present invention, and the hair transplant prevention mask 6 is divided into a plurality of arbitrarily shaped pieces as shown in FIGS. 4 to 6. 6
As shown in FIGS. 7 to 10, colored piles of different colors are successively implanted while removing the fibers one after another as shown in FIGS. 7 to 10.

By dividing the hair-planting prevention mask 6 into a plurality of pieces in this way and transplanting colored piles of different colors while removing the hair-plantation prevention mask 6 one after another, there is an effect that a complex design pattern can be easily transplanted. In the present invention, after a sparse flocking surface is formed by planting piles in a sparse manner on the flocking surface, a part of the sparse flocking surface is covered with a hair flocking prevention mask of an arbitrary shape. is supported by the piles that are flocked on the sparse flocked surface and is directly taught to the sparse flocked surface, so that the gap between the flocked surface and the hair flocking prevention mask is reduced to 4.
Since only the same gap is created, there is no fear that colored piles will invade the area covered by the hair-plant prevention mask and cause hair-plantation, resulting in a clear boundary line.

Since the hair transplant prevention mask is directly supported by the pile 4,
This has the effect that no backing material is required to support the anti-hair transplant mask.

Since the piles 4 are sparsely implanted in the area covered with the hair transplant prevention mask, the piles 4 function as a blocking shelf to prevent the colored piles 7 and 8 from entering.
.

The colored pile 7 is covered with a hair flocking prevention mask to form a sparse flocked surface 5.
Then, the hair transplantation prevention mask is removed, the part where the colored piles 7 have been implanted is covered with the hair transplantation prevention mask, and colored piles 8 of different colors are implanted on the sparse flocked surface 5, so that hair transplantation can be prevented. Multicolor hair transplantation is possible simply by removing and attaching the mask, resulting in extremely high hair transplantation efficiency. Since the method and the apparatus used for the method are extremely simple, they are inexpensive and can be easily carried out without requiring considerable skill.

EXAMPLE A flocking adhesive made of an emulsion type acrylic resin adhesive was uniformly applied to the surface of a raised base fabric in an arbitrary shape using a screen and a squeegee to form a flocking surface.

Next, using an electrostatic flocking device using a down method, transparent two-skin length nylon and pile were flocked in a sparse manner on the flocked surface to provide a sparse flocked surface. In this case, the flocking density of the transparent nylon pile was approximately 10 strands/hair. A waterproof paper flocking prevention mask formed in the same shape as the sparse flocking surface is divided into two parts, and one of the divided hair flocking prevention masks is placed over a part of the sparse flocking surface. It was placed and fixed on a transparent nylon pile.

Next, a 2-length nylon pile dyed in red was transplanted using the electrostatic flocking device, uniformly and at a normal flocking density onto the sparse flocked surface on which the flocking prevention mask had not been reapplied.

Furthermore, after removing the hair-planting prevention mask from the wisteria-like hair-planting surface, the other hair-planting prevention mask was applied to cover and fix the entire surface of the part where the red nylon pile was planted. Next, using the electrostatic flocking device described above, a green-dyed nylon pile with a length of 2 ribs is planted uniformly on the remaining part of the sparse flocked surface and at a normal flocking density, and then allowed to dry naturally. After removing moisture, it was heat-treated in a drying oven at 140 qo for 1 minute.

The resulting product has a clear color-coded pattern created by the red and green flocked areas and the color of the base fabric, and the boundaries between the mutual color patterns are sharp and clear in the form of a single line. It was being expressed.
