DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a velvet-like electrostatic flocking cloth and a method of manufacturing the same, and for example, relates to an electrostatic flocking technique capable of producing a uniform color and a clear pattern or pattern.

[0002]

2. Description of the Related Art As one of nonwoven fabrics, a velvet (velvet) nonwoven fabric in which short fibers are implanted vertically in an adhesive layer formed on the surface of a substrate is known.

In the production of the above velvety nonwoven fabric,
For example, a short fiber (flock) for flocking is arranged below a base material coated with an adhesive on the lower surface, and an electrode is arranged above the base material to apply a high voltage to polarize the short fiber. In addition, the nonwoven fabric (electrostatic flocking cloth) is manufactured by sucking the substrate by electrostatic force and implanting the adhesive layer with the adhesive, and then curing the adhesive layer.

[0004] Regarding the electrostatic flocking technique, "The New Edition of Electrical Engineering Handbook" published by the Institute of Electrical Engineers of Japan (IEICE),
It is described in P1856 issued in 1988.

00% Utilization ", P135 and P136, describe flocking (flocking).

[0006] In this document, short fibers having a length of 0.3 to 5 mm are woven by using an electrostatic high voltage (10 kV or more) to fabric, paper,
It describes that hairs are vertically or diagonally implanted on a base material such as metal or foam.

[0007]

Conventionally, coloring and pattern formation of an electrostatic flocking cloth have been performed by dyeing after electrostatic flocking.

[0008] Since the dyeing is performed on the raised fabric, it is difficult for the dye to penetrate between the hairs. As a result, color unevenness occurs and the velvet-like texture is impaired. Further, if color unevenness occurs in the outline of a pattern such as a pattern or a picture, the pattern becomes unclear, and a beautiful picture or the like cannot be obtained, and the commercial value decreases.

On the other hand, there is a technique for obtaining a velvet-like texture using a foaming paint, but the texture is still different.

An object of the present invention is to provide an electrostatic flocking cloth having a pattern in which the velvet-like texture is not impaired by the electrostatic flocking technique.

It is another object of the present invention to provide a sharply patterned electrostatic flocking cloth which does not impair the velvet-like texture and a method for producing the same.

Another object of the present invention is to provide an electrostatic flocking cloth having a clear multicolored pattern, which does not impair the velvet-like texture, and a method for producing the same.

This print pattern is selected by the selective flocking device 11a.
In the case of (1), the pattern is the hatching pattern shown in FIG.
The pattern shown in FIG. 1B is a dot-patterned pattern. In the case of the selective flocking device 11c, the pattern is hatched in the downward right direction shown in FIG.

The electrostatic flocking cloth 4 which has become a square cloth is sequentially stored in the storage box 70.

The adhesive layer 2 may use a resin other than a thermosetting resin or a thermoplastic resin. For example, a catalyst-curable resin composed of a main agent and a curing agent, or an ultraviolet-curable resin may be used. In this case, for the curing treatment of the resin, an apparatus suitable for the treatment may be incorporated in the production line.

According to the method for manufacturing the electrostatic flocking cloth of the first embodiment and the manufactured electrostatic flocking cloth, the following effects can be obtained.

(1) The adhesive layer 2 is selectively formed on the surface of the substrate 1.
Is formed and the short fibers 3 are planted on the adhesive layer 2 by using a selective flocking method, and the short fibers 3 having different colors are used in each selective flocking process. Since printing is not performed after flocking as in the related art, color unevenness due to printing variations does not occur, and the velvet-like texture (feel) of the manufactured electrostatic flocking cloth 4 is not impaired.

(2) Since the short fibers 3 having different colors are planted on the base material 1 by dividing the regions, the boundaries between the regions become clear, and the electrostatic flocking cloth 4 has a clear multicolor pattern.

(3) Since the electrostatic flocking cloth 4 having a clear multicolor pattern without color unevenness can be manufactured, the yield is improved,
Manufacturing costs can be reduced.

(4) After forming the adhesive layer 2 selectively,
Since the short fiber 3 can be implanted only in the portion where the adhesive is present, and the method of repeating the selective implantation by a series of operations such as formation of the adhesive layer, implantation, and curing is repeated a plurality of times, the production system is also required. It is simple and the manufacturing cost can be reduced.

(5) A desired pattern can be easily formed by forming the adhesive layer 2 in accordance with a predetermined image pattern, that is, by forming the adhesive layer 2 by a screen printing method or an ink jet printing method. it can.

Therefore, in the case where the color is simply changed by vertically or obliquely flocking short fibers having mutually different dimensions on the base material in each selective flocking step. Can be obtained with a texture that cannot be obtained.

The embodiments will be described below.

(Embodiment 2) FIG. 4 shows Embodiment 2 of the present invention.
It is a typical sectional view of the electrostatic flocking cloth which is.

Embodiment 2 is an example in which the length of the short fiber 3 is changed.

As shown in FIG. 4, three types of short fibers 3 are vertically implanted in the adhesive layer 2 of the base material 1 in divided regions (a, b, c). Assuming that the length of the short fibers 3 in the region b is standard, the short fibers 3 in the region a are short and the short fibers 3 in the region c are long.

As a result, by freely combining these areas, it is possible to create a pattern using only the short fibers 3 of the same color, and to enjoy a difference in feel. Further, the combination with the color makes it possible to increase the depth of the texture and enjoy a further texture, thereby increasing the commercial value.

(Embodiment 3) FIG. 5 shows Embodiment 3 of the present invention.
It is a typical sectional view of the electrostatic flocking cloth which is.

The third embodiment is an example in which the thickness of the short fibers 3 to be planted is changed.

As shown in FIG. 5, three types of short fibers 3 are vertically implanted in the adhesive layer 2 of the base material 1 in regions (a, b, c). Assuming that the thickness (diameter) of the short fibers 3 in the area a is standard, the short fibers 3 in the area b are thin and the short fibers 3 in the area c are thick.

As a result, by freely combining these areas, it is possible to create a pattern using only the short fibers 3 of the same color, and also to enjoy a difference in feel. Furthermore, the combination of colors and the combination of colors and lengths allow the user to enjoy a further texture, thereby increasing the commercial value.

(Embodiment 4) FIG. 6 shows Embodiment 3 of the present invention.
It is a typical sectional view of the electrostatic flocking cloth which is.

The fourth embodiment is an example in which the short fibers 3 to be planted are the same in each region, but the direction of the planting to the base material 1 is different for each region.

As shown in FIG. 6, the short fibers 3 of the same type are planted in the adhesive layer 2 of the base material 1 vertically or obliquely by dividing the areas (a, b, c). The short fibers 3 in the region b are planted perpendicularly to the substrate 1.

On the other hand, the short fibers 3 in the region a are
Slanted flocking so as to have an angle of β with respect to the surface of
The short fibers 3 in the region c are obliquely planted so as to have an angle of α with respect to the surface of the substrate 1.

In the fourth embodiment, the short fibers 3 are planted at an obtuse angle in the area a, and the short fibers 3 are implanted in the area c.
Is implanted with an acute angle of inclination, but is not limited thereto.

Since the light reflectance differs between the vertical flocking area and the inclined flocking area, and the light reflectance differs depending on the inclination angle also in the inclined flocking area, the vertical flocking area and the inclined flocking area are arranged in combination. By performing the selective flocking as described above, it is possible to create a difference in pattern and hand even when the same type of short fiber 3 is used.

Thus, an unusual texture can be enjoyed.

Further, by adopting the difference in the flocking angle and by combining the flocking methods of the first to fourth embodiments, it is possible to create an electrostatic flocking cloth 4 having a further different texture.

(Embodiment 5) FIGS. 7 to 9 relate to a method for manufacturing an electrostatic flocking cloth and an electrostatic flocking cloth according to Embodiment 5 of the present invention.

FIG. 7 is a schematic view showing a part of the electrostatic flocking system, FIG. 8 is a schematic enlarged view showing the electrostatic flocking state, and FIG. 9 is a plan view schematically showing the electrostatic flocking state of the electrostatic flocking cloth. FIG.

In the fifth embodiment, two selective flocking devices are arranged in series and perform two selective flocking.

As shown in FIG. 7, the hoop-shaped base material 1 unwound from the roll 10 is applied to a pair of rollers 25,
An adhesive layer is formed on the entire lower surface during the movement between 26.

That is, in the adhesive layer forming apparatus 20, the lower part of the lower roller 26 of the pair of rollers 25, 26 is immersed in the adhesive liquid 28 stored in the tank 27. An unillustrated adhesive layer is formed on the lower surface of the substrate 1 by the rotation of the pair of rollers 25 and 26.

In the fifth embodiment, as shown in FIG. 7, the electrostatic selective flocking device 30 is provided near the upper side of the base material 1 so that the lower surface of the base material 1 can be planted. A charging electrode 32 is arranged, and separated from the ground electrode 31 under the substrate 1.
Is arranged. The portion far away from directly below the charging electrode 32 also serves as a short fiber supply dish on which the short fibers 3 are placed.

On the other hand, this is one of the features of the present invention. The charging electrode 32 is smaller than the ground electrode 31. As a result, as shown in FIG. 7, the electric force lines 37 do not become parallel at the edge of the charged electrode 32 but draw a curve that converges toward the edge of the charged electrode 32. And the electric lines of force 3 that draw this curve
The short fibers 3 are implanted by using 7.

That is, the electrostatic flocking cloth 4 of the fifth embodiment.
As shown in FIG. 9 and FIG. 8, the base material 1 has a cured adhesive layer 2 on one surface thereof, and short fibers 3 are vertically implanted in the adhesive layer 2. The edge portion of the vertical flocking region 80 is an inclined flocking region 81 in which the short fibers 3 are inclined and transplanted.

The inclined flocking region 81 is formed by utilizing the difference between the shape of the charged electrode 32 and the direction in which the electric force lines 37 extend at the edge of the charged electrode 32 as described above.

As shown in FIG. 7, at the edge of the pattern of the charging electrode 32, the direction of the electric flux lines 37 is inclined so as to gradually approach the base material 1 as the distance from the pattern is increased. At 81, the planted short fibers 3 gradually tilt as they deviate from the pattern.

For example, when the pattern of the charging electrode 32 is star-shaped, the pattern of the vertical flocking area 80 becomes a star shape as shown in FIG. . In FIG. 9, the vertical flocking area 80 is dotted, and the slant flocking area 81 is shown with a short line.

By such selective flocking, the pattern comes to rise, and the electrostatic flocking cloth 4 can enjoy the texture visually and tactilely.

On the other hand, even if the adhesive layer 2 is provided on the entire lower surface of the base material 1, flocking is not performed on a portion where the electrostatic force of the charging electrode 32 does not reach. In this way, the flocking corresponding to the pattern of the charging electrode 32 is selectively performed.

In the second selective flocking device,
In the electrostatic selective flocking device 30b, a charging electrode 32b having a pattern opposite to the pattern of the charging electrode 32 is arranged, and another short fiber 3 is flocking in a star-shaped outer region formed by the charging electrode 32. It is supposed to.

The selective flocking is not limited to this.

The method of manufacturing the electrostatic flocking cloth of Embodiment 5 is as follows.
A method of manufacturing an electrostatic flocking cloth by forming an adhesive layer 2 on a flocking surface of a base material 1, then implanting short fibers 3 by electrostatic flocking, and then curing the adhesive layer 2. (Charged electrode) After preparing an electrode having an uneven surface or an electrode having a predetermined electrode shape, a hair is partially and obliquely implanted in the adhesive layer by utilizing a difference in the direction of lines of electric force between the electrodes. Things.

According to the fifth embodiment, a part of the short fibers is inclined and implanted by utilizing the difference in the direction of the lines of electric force between the electrode having an uneven electrode surface and the electrode having a predetermined electrode shape. Therefore, a pattern having a different texture can be formed depending on the difference in the light reflectance of the inclined portion.

In the fifth embodiment, after forming the adhesive layer 2, the first short fibers 3 are used to implant a star-shaped pattern, and then the second short fibers are applied to the outer region of the star. The hair may be implanted, and then the adhesive layer may be cured.

According to this method, the formation process and the curing process of the adhesive layer are performed once, respectively, so that the process can be shortened and the facility can be simplified.

When the colors of the first short fibers and the second short fibers are different, at the border of the flocked region, the color is different from one region toward the other region and from the other region toward the one region. The number of flocks of color short fibers will also change,
The pattern also has a zone in which the color changes continuously, and a different texture can be enjoyed.

Although the invention made by the inventor has been specifically described based on the embodiment, the invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the invention. Needless to say.

For example, when the adhesive layer 2 is formed by an ink-jet printing method, and when the adhesive layer 2 is formed by a catalyst-curable adhesive composed of a main agent and a curing agent, the main agent and the curing agent are different. By blowing out from the nozzle, clogging that occurs when the adhesive hardens at the nozzle portion can be prevented, and workability is improved.

In this case, the blowing of the main agent and the curing agent is 2
The configuration may be such that the apparatus is operated simultaneously with the nozzles, or the apparatus is configured in two stages by changing the work station.
