DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mesh sheet for oil-based ink-jet printing suitable for drawing and printing an image with oil-based ink using an ink-jet printer. More specifically, the present invention is useful for an advertisement medium, a notice medium, a awning tent, a blind, a sheet for construction work, a sheet for sports facilities (for example, a sheet for shading a tennis court, etc.), and an ink jet printer. The present invention relates to an oil-based inkjet printing mesh sheet that can be used to print an oil-based ink image easily and with high production efficiency. The oil-based ink-jet printing mesh sheet of the present invention is very easy to perform a toning operation when printing, the image drawn on the oil-based ink receiving layer surface is clear, and the oil-based ink receiving surface of the mesh sheet is used. The image drawn on the back side of the mesh sheet (the oil-based ink non-receptive surface) is hardly seen through the back side (oil-based ink non-receptive surface) of the mesh sheet. This has the advantage that the hue can be maintained.

[0002]

2. Description of the Related Art Oil-based ink is printed on a mesh sheet by an ink-jet method to obtain a desired image (character,
It is practical to draw a pattern or the like and use it as an advertisement medium, a notice medium, a sheet for construction work, and a light-shielding sheet for a sports facility (for example, a light-shielding sheet for a pool or a tennis court). As a mesh sheet used for the purpose, a mesh sheet obtained by using a fiber yarn as a base fabric, and the upper surface of the constituting yarn is coated with a soft polyvinyl chloride resin has been used.

[0003] In such a conventional soft polyvinyl chloride resin-coated mesh sheet, at least a part of the liquid plasticizer contained in the soft polyvinyl chloride-based resin exudes to the coating surface with the passage of time. In some cases, the exuded liquid plasticizer swells the oil-based ink drawn on the resin layer and eventually causes the oil-based ink to fall off. To prevent this inconvenience,
It was necessary to use a special, oil-based ink that did not swell with the liquid plasticizer (for example, trade name; Sericol®, manufactured by Teikoku Ink). However, such special oil-based inks may not always be compatible with the ink jet printing method, and therefore, it is necessary to carefully select them.

Conventionally, mesh sheets used for oil-based ink-jet printing have a large white color and the mesh sheet covered with a soft polyvinyl chloride resin has low light-shielding properties.
When drawing an image with oil-based ink on the surface (drawing surface),
This image is displayed on the other side (non-drawing side) of the mesh sheet.
There is an inconvenience of appearing as a blurred image, especially when the illuminance on the drawing surface of the mesh sheet is higher than the illuminance on the non-drawing surface, the image drawn on the drawing surface can be seen through the non-drawing surface, It may cause discomfort to those located on the side.

[0005] The mesh sheet originally has a large number of holes formed in the gaps between the constituent yarns, and the holes transmit light. Therefore, conventionally, the mesh sheet has been used for the purpose of increasing the illuminance of the inner space surrounded by the mesh sheet by utilizing the light transmitted through the yarn gap holes. In this case, almost no processing was performed to intentionally increase the light blocking ratio of the yarns constituting the mesh sheet to reduce the amount of light transmitted through the mesh sheet. As described above, since the light transmittance of the yarns constituting the mesh sheet is high (the light-shielding rate is low), the image drawn on the drawing surface of the mesh sheet can be displayed on the non-drawing surface on the opposite side of the mesh sheet. Is unnecessarily and unclearly transmitted.

Further, when the Munsell brightness of the non-drawing surface of the mesh sheet is high, light projected from the non-drawing surface side of the mesh sheet is reflected on the non-drawing surface of the yarn constituting the mesh sheet, and this reflected light is reflected. Then, the light is transmitted through the yarn gap holes from the drawing surface side of the mesh sheet and mixed with the light that has entered the non-drawing surface side, thereby making the optical information by the transmitted light unclear and lowering its resolution.

Further, when the light shielding property of the yarns constituting the mesh sheet is low, the light projected from the drawing surface of the mesh sheet is refracted intricately in the yarns constituting the mesh sheet and is transmitted while being irregularly reflected. The transmitted light mixes with the light that has passed through the yarn gap voids of the mesh sheet, blurring the light information and reducing its resolution.

In general, the light-shielding property of a mesh sheet decreases as the thickness of the constituent yarns decreases. For example, in a coarse knitted fabric knitted and woven with a yarn of 750 denier or less,
When the Munsell brightness on the drawing surface side is maintained at 9.0,
Even if soft polyvinyl chloride resin having intentionally increased light concealment is applied to the yarn of the mesh sheet and the amount of the applied resin is set to 60 to 150% of the weight of the coarse knitted fabric base cloth, sufficient light shielding is obtained. It is empirically known that no sex is obtained.
That is, even if such a light-shielding process is performed, the above-mentioned inconvenience cannot be avoided. Thus, there has been a strong demand for the appearance of a mesh sheet for oil-based inkjet printing, which can practically avoid the above-mentioned disadvantages.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a mesh sheet suitable for ink-jet printing using oil-based ink. In particular, the present invention provides an oil-based inkjet printing mesh sheet, in which one side of the constituent yarns of the coarse knitted fabric forming the base fabric has an oil-based ink receiving surface, and the other side has an oil-based ink non-receiving surface. Formed on the oil-based ink receiving surface, a clear oil-based ink image of a desired hue can be drawn, and
This oil-based ink image cannot be seen through or is difficult to see through from the surface of the oil-based ink rejection layer, and attempts to make the oil-based ink rejection surface have a uniform hue. .

[0011]

FIG. 1 is a plan view showing an example of a mesh sheet for oil-based ink jet printing according to the present invention, and FIG. 2 is a line A- of the mesh sheet shown in FIG.
A cross-sectional view along A 'is shown. 1 and 2, a mesh sheet 1 for oil-based inkjet printing
Is a plain woven fabric woven from a large number of warp yarns 1a and weft yarns 1b. These warp yarns 1a and weft yarns 1b are made of fiber yarn impregnated or coated with a synthetic resin. In the mesh sheet 1, the woven warps 1a and the wefts 1b form a large number of holes 1c as a gap between the yarns, and pass through the holes 1c from one side of the mesh sheet to the other side. You can see through. In FIG. 2, only the crossed warps 1a and the gap holes 1c are shown, and the description of the wefts 1b intersecting with the warps 1a is omitted.

FIG. 3 shows the warp 1 shown in FIG. 1 and FIG.
a, a cross-sectional enlarged view is shown. In FIG. 3, a warp yarn 1a is composed of a raw yarn 2 composed of a number of fibers, an upper surface side soft polyvinyl chloride resin layer 3 impregnated or coated on the upper surface side of the raw yarn 2 and fixed thereto. Acrylic resin coating layer 4 covering the upper side of the soft vinyl chloride resin layer 3 on the upper side, and a lower side soft polyvinyl chloride resin impregnated or coated on the lower side of the yarn 2 and fixed. And a layer 5. The upper surface side and lower surface side soft polyvinyl chloride-based resin layers may penetrate at least a part of the yarn 2 into the fiber gap and may be fixed.

In the mesh sheet of the present invention, the soft polyvinyl chloride-based resin layer formed on one side (oil-based ink receiving surface side) of the raw yarn and the acrylic resin-coated layer formed thereon are respectively It has a Munsell brightness of 9.0 or more, and accordingly, the Munsell brightness of the oil-based ink receiving resin layer composed of these two resin layers is 9.0 or more. On the other hand, the Munsell degree of the soft polyvinyl chloride-based resin layer formed on the opposite surface side (the oil-based ink non-receiving surface side) of the raw yarn is adjusted to 2.4 or less. By doing so, the hue of the oil-based ink ejected from the oil-based ink-jet printer and the hue of the oil-based ink image formed on the oil-based ink receiving surface (the acrylic resin coating layer surface) of the mesh sheet become very similar. Become.

The mesh sheet of the present invention comprises a soft polyvinyl chloride resin layer and an acrylic resin coating layer formed on one side of the fiber yarn,
An oil-based ink receiving layer having a Munsell brightness of 9.0 or more is formed. On the opposite side, a soft polyvinyl chloride-based resin layer is formed, and an oil-based ink rejection layer whose Munsell brightness is adjusted to 2.4 or less is formed. When formed, the light-shielding rate of this resin-coated yarn must be 80% or more.
% Or more, the denier of the fibrous yarn is 750.
It is preferably at least denier. The light-shielding rate of the resin-coated yarn is preferably 90% or more.

When the denier of the original yarn is less than 750 denier, it is difficult to make the overall light-shielding ratio 80% or more even if the light-shielding ratio of the coating resin layer is increased because the yarn is thin. If the light-shielding ratio of the resin-coated yarn is less than 80%, an image drawn on the oil-based ink receiving surface is seen through from the oil-based ink non-receiving surface side. As described above, the light-shielding rate of the resin-coated yarn needs to be 80% or more, and preferably 90% or more. In order to make the light-shielding rate of the resin-coated yarn 90% or more, a metal layer having a thickness of 400 Å or more is formed on at least one surface of a base fabric made of a coarse knitted woven fabric composed of fiber yarns. Is preferred. Further, a metal film layer having a thickness of 400 Å or more may be formed in the resin layer on the oil-based ink receiving surface side of the resin-coated yarn. However, in order to simplify the operation of adjusting the color of the oil-based ink, the oil-based ink receiving layer needs to have a hue having a high lightness and a high light-shielding property. Even when aluminum is deposited on the receiving layer side resin layer, light projected from the non-drawing surface side is reflected on the aluminum deposited film surface,
This reflected light mixes with light that has passed through the yarn gap holes from the drawing surface side of the mesh sheet and has entered the non-drawing surface side, thereby blurring the optical information due to the transmitted light and reducing its resolution.

The metal film layer is formed by a metal vapor deposition method, a metal sputtering method, a metal spraying method, a method of transferring a metal vapor deposited layer formed on a plastic film, a method of applying a paint containing fine metal particles as a main component, and the like. Can be appropriately selected and used. Further, as the metal used for the metal film layer,
There are aluminum, zinc, titanium, silver, and the like, and aluminum is preferably used.

As described above, in the mesh sheet of the present invention, the soft polyvinyl chloride-based resin layer on the oily ink non-receptive side is colored so that the Munsell lightness becomes 2.4 or less, particularly black. You. However, the soft polyvinyl chloride resin layer on the oil-based ink receiving surface side may be achromatic or chromatic, but the Munsell lightness is controlled to 9.0 or more. Generally, at the time of oil-based ink printing, the oil-based ink receiving surface is preferably an achromatic color in order to easily adjust the hue of a printed image. The soft polyvinyl chloride resin used for either the oil-based ink receiving surface or the non-receptive surface may be a paste (paste) produced by a known method such as an emulsion polymerization method, and may be either a plastisol or an organosol. Or straight vinyl chloride.

The fibers constituting the coarse knitted fabric for the base fabric of the present invention are not particularly limited. For example, natural fibers such as cotton and hemp, for example, inorganic fibers such as glass fiber, metal fiber and carbon fiber, for example, nylon 6 And at least one selected from synthetic fibers such as nylon 66, polyester (PET), polyvinyl alcohol, and aromatic polyamide fibers. There is no limitation on the cross-sectional shape, form, thickness, size, etc. of these fibers, and any of long fibers and short fibers may be used. Any of a spun yarn, a monofilament, a tape yarn, a split yarn, and a composite yarn of two or more of these may be used. Furthermore, the structure, size, shape, etc. of the coarse knitted fabric are not limited as long as it has a desired coarse structure, and may be any of plain weave, entangled weave, if weave or weave, warp or weft insertion Russell knit, etc. There may be.

In the mesh sheet of the present invention, a number of fine irregularities are formed on the surface of the soft polyvinyl chloride resin layer and the acrylic resin coating layer on the oil-based ink receiving surface side and the non-receiving surface side. It is preferable to improve the light-shielding properties of the resin-coated yarn.

The acrylic resin used in the present invention is at least one selected from methyl methacrylate resin, methyl acrylate resin, ethyl acrylate resin, butyl acrylate resin, methyl ethyl acrylate resin, and the like. Preferably comprises
At least one selected from a vinyl chloride-vinyl acetate copolymer resin, an ethylene-vinyl chloride copolymer resin, an ethylene-based resin, a urethane-based resin, a fluorine-based resin, and the like may be mixed.
The acrylic-based resin coating layer can prevent the plasticizer in the soft polyvinyl chloride-based resin layer impregnated or applied to the original yarn from oozing over the oil-based ink receiving surface with the passage of time. For this reason, the printed oil-based ink is
There is no swelling due to the plasticizer transferred to the surface.
In addition, the surface of the acrylic resin coating layer has high adhesiveness to the oil-based ink, and can firmly hold the same for a long period of time. If the oil-based ink is printed directly on the soft polyvinyl chloride resin layer without coating the acrylic resin coating layer on the soft polyvinyl chloride resin layer, the ink in the printed oil-based ink image is printed. With the use vehicle, the plasticizer is extracted from the soft polyvinyl chloride-based resin layer, and the oil-based ink image swells and eventually falls off. Therefore, such an oil-based ink image cannot be held for a long time.

In the mesh sheet of the present invention, the Munsell lightness of the oily ink receiving surface is controlled to 9.0 or more, and the Munsell lightness of the oily ink non-receiving surface is controlled to 2.4 or less. Is controlled to be 80% or more, preferably 90% or more. Therefore, even when an oil-based ink having a low lightness and a high light-shielding ratio is used, the resin-coated yarn can be removed from the oil-ink-insensitive surface of the mesh sheet. Through, it is not possible to see through the oil-based ink image, or because it is difficult, the oil-based ink rejection surface of the mesh sheet,
It exhibits a uniform hue and is not or very little affected by the oily ink image on the oily ink receiving surface. Further, since the oil-based ink receiving surface has a Munsell brightness of 9.0 or more, the hue of the oil-based ink supplied by inkjet and the hue of the oil-based ink image drawn on the oil-based ink receiving layer are different. , Very similar. For this reason, the toning of the oil-based ink becomes extremely easy.

In the mesh sheet according to the present invention, if the light-shielding rate of the resin-coated yarn is less than 80%, among the oil-based ink images drawn on the oil-based ink receiving surface, the image formed by the oily ink having a low lightness and a high light-shielding rate. The portion is seen through the resin-coated thread from the oil-based ink non-receptive surface side, so that the oil-based ink non-receptive surface has an unsightly appearance. When the Munsell lightness of the oil-based ink receiving surface is less than 9.0,
Under the influence of the lightness of the receiving surface, a difference occurs between the hue of the printed oil-based ink itself and the hue of the drawn oil-based ink image. Inconveniences such as a long time and a high cost are required for the toning operation. Further, when the Munsell lightness of the oil-based ink non-receptive surface is higher than 2.4, the reflected light on the oil-based ink non-receptive surface increases, and this reflected light passes through the thread gap holes of the mesh sheet and the oil-based ink non-receptive surface. The light is mixed with light information (for example, a landscape image) irradiated on the receiving surface side to reduce the resolution and obscure the resolution.

The oil-based ink jet printer discharges the oil-based ink onto the oil-based ink-receiving surface of the oil-based ink-jet print mesh sheet of the present invention, and the drawn image is extremely clear and faithfully reproduces the hue of the discharged oil-based ink. are doing. Further, the printed image is hardly seen through the non-drawing surface of the mesh sheet opposite to the oil-based ink receiving layer surface, and a substantially uniform hue surface can be obtained. In addition, oil-based ink toning before drawing is extremely easy,
It is very economically effective. In addition, since the oil-based ink receiving surface is formed of an acrylic resin coating layer, the plasticizer contained in the soft vinyl chloride resin layer is not extracted into the drawn ink layer, and the ink image can be used for a long time. It is kept the same when drawing. Also, even in a dry and humid environment, the plasticizer contained in the soft vinyl chloride resin layer is not extracted into the ink layer, so that the drawn oil-based ink does not swell, and the drawn oil-based ink and the oil-based ink receiving layer Since the adhesive strength with the mesh is maintained for a long time, the drawn mesh sheet can be used outdoors for a long time, and its practical value is extremely high.
