Description

[Detailed description of the invention] The present invention provides a windbreak net, a curing sheet, a paint scattering prevention sheet,
The present invention relates to a so-called letter/character adhesion part such as a cutout cloth for displaying letters, figures, etc. on a coarse sheet used for sports seats, decorative tents, etc., or a cutout cloth for example, a white cutout cloth on which letters, figures, etc. are written after sticking.

Conventionally, when displaying required letters and figures such as a company name on a curing sheet, etc., there is no problem if the sheet is made of a woven fabric whose constituent yarns have a moderate density and the surface is covered with a synthetic resin film, such as a tarpaulin. However, in the case of coarse sheets, which have recently become particularly popular as curing sheets, it is extremely difficult to display characters directly on the sheets using ink, and even if it is possible to display characters, However, when the back is bright, phenomena such as being almost invisible from the front occur, and
There were inconveniences such as a large amount of ink being wasted during display.

Therefore, the method of cutting out the letters and face and pasting them with adhesive etc. has been used, but conventional coarse sheets are made of woven synthetic fibers such as polyethylene, polypropylene, vinylidene chloride, etc. Since the yarn was coated with a resin such as vinyl chloride in advance and knitted or woven, the surface of the yarn was hardened by the resin, making it difficult for adhesives etc. to bond to it. With conventional coarse-grained sheets, the warp and weft yarns do not join together at their intersections, so when the adhesive is applied, the yarns tend to shift, making the attachment areas unsightly, which makes it difficult to use perforated yarns. The adhesion strength decreased due to the movement of the inside, and one character/face came off early, which was not suitable.

The present invention was made in view of the above circumstances, and firstly, the structure of the coarse sheet itself is completely different from that of conventional sheets of this type, and the fibrous yarns are oriented in the weft and warp directions. A coarse knitted fabric made of a relatively coarse knitted fabric is used as an interlining, and a thermoplastic resin is adhered to the entire interlining so that each thread in the weft and warp direction of the interlining is integrally joined at the intersection of both. The important feature of this sheet is that the warp and warp yarns are integrally joined at their intersections by thermoplastic resin, so each yarn does not shift or fall out at all, and the characters are straight.・Even when pasting with adhesives or adhesives, such as when cutting out characters, reliable adhesion is always guaranteed and it is possible to prevent unnatural forces from being applied due to the movement of threads during use. The present invention is based on the premise that such a coarse sheet is used to adhere letters and fonts, and an object of the invention is to form adhesive portions that are far superior to those of the prior art.

As described above, in order to construct an excellent adhesion part for letters and fonts, in the present invention, A. Coated on the surface of letters and fonts having a desired shape and size in any part of the coarse sheet. Threads to which thermoplastic resin can be attached are embedded in a layer of adhesive or adhesive.

B. A pressure-sensitive adhesive or adhesive applied to the back side of characters/fonts having a desired shape and size on any part of the coarse sheet, and a adhesive or adhesive having a size equal to or smaller than the characters/fonts. A sheet-like material that is joined to the face of the characters through a coarse sheet, and a thread to which a thermoplastic resin is attached is embedded in the pressure-sensitive adhesive or adhesive layer.

There are two aspects.

All of these are effective, but (B) in particular has a sheet-like material that is crosslinked through a coarse sheet, so it has strength, good appearance, and no staining at the bonded part. It has many advantages and can produce remarkable effects.

The present invention will be explained in more detail below.

The fibrous yarn according to the present invention is made of natural fiber, synthetic fiber, inorganic fiber, etc., and polyester, vinylon, etc. are particularly suitable.

Further, the yarn may be any other yarn such as spun yarn, filament yarn, split yarn, tape-like yarn, etc., and is not limited to any particular type.

However, polyester or vinylon filament yarns are particularly preferred in consideration of strength, fabric weight, and other properties.

These threads can be arranged in the weft and weft directions and woven in any way, but plain weave is common, and other known special fabrics such as leno weave and leno weave are also used. , or may be knitted if necessary.

Further, the mesh size of the knitted interlining is preferably 15 mm x 15 mil if it is square, or less than 225 m4, and particularly 0.5 to 10 rILm square.

In addition, the warp and warp threads do not necessarily have to be arranged perpendicularly to each other, but may be arranged so that the weft threads are slightly arched relative to the warp threads, and furthermore, the entire interlining does not have eyes of the same size. However, it is also possible that the threads in the warp direction in some parts, for example at the ends, are arranged closely to make the strength of the part more uniform.

Next, the coarse sheet according to the present invention has the above-mentioned interlining.
The thermoplastic resin is adhered to the entire interlining to a sufficient extent that the yarns in the weft and weft directions of the interlining are integrally joined at the intersections thereof.

At this time, the resulting sheet becomes flexible and strong due to the adhesion of the thermoplastic resin.

Thermoplastic resins usually have high frequency fusion properties or heat fusion properties, such as polyvinyl chloride, urethane resin, ethylene-
Although vinyl acetate copolymers and other materials may be used, those mainly composed of vinyl chloride resin are particularly preferred.

The thermoplastic resin is preferably applied in a range of 70 to 200 weights on the interlining weight of 50 weight plates.

Adhesion is achieved by dipping the interlining in a resin solution, drying and optionally gelling.

Attachment can also be by coating or other known methods.

When adhering, it is necessary to cover and grip the resin sufficiently to ensure that the warp and warp threads are joined together as a whole, especially at their intersections.

Next, the characters and faces applied to such a coarse sheet will be explained.

The letters and faces are pasted on cloth or sheets that have been cut out in advance according to the desired letters, figures, etc., and then the desired letters and faces are pasted on the cloth or sheet.
It is a general term for, for example, a white cut-out piece of cloth on which a figure or the like can be written, and a pressure-sensitive adhesive or adhesive is applied to the back side, that is, the side to be stuck to the coarse sheet.

The thickness of the adhesive or adhesive is appropriately selected depending on the type of rice grain sheet, but it should be thick enough to form a layer and embed the threads to which the thermoplastic resin is attached as described below. is necessary.

The following are preferably used as adhesives and adhesives:

Examples of adhesives include natural/synthetic rubber, resynthetic rubber,
Polyisobutylene, polyviny/L/x-te/L/.

Adhesive agents such as polyacrylic acid ester, polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, etc., rosin, ester gum, polyterpene, petroleum resin, xylene resin, oil-soluble phenol resin, coumaron indene. Tackifiers such as resins,
Other plasticizers.

Examples include pressure-sensitive adhesives containing fillers, anti-aging agents, and the like.

However, the material is not limited to this, and any material may be used as long as it achieves the purpose of attachment.

Further, the adhesive is not particularly limited, and any known adhesive may be used as long as it meets the purpose of the present invention.

The present invention will be further described in detail below based on embodiments with reference to the drawings.

FIGS. 1A to 1C are plan views of coarse sheets to which the present invention is applied.

The most common coarse sheet is one that is woven into a plain weave using threads 1 and 2 arranged in the weft and weft directions and having approximately square meshes, as shown in A.

In addition, as shown in B, there are some plain fabrics in which the density of the threads is slightly higher in some parts, but in this case, the part of the layer with the same density is joined to the same part of the adjacent sheet, so that the joining strength is reduced. There is an advantage that a dog joint is obtained.

Furthermore, in the case of C in the same figure, the weft or warp yarns are arranged in a slightly arc shape with respect to either the warp or weft yarns, and there are many intersection points between adjacent sheets. This can have the effect of increasing the joint strength.

Furthermore, in the case of the same figure, the state of adhesion of the thermoplastic resin at the intersection of each yarn 1 and 2 is shown.

By adhering the thermoplastic resin 3, the warp and weft threads 1.2 are fixed to each other.

Next, FIGS. 2A and 2B are explanatory diagrams according to the first invention of the present application, and FIGS. 3A and 3B are explanatory diagrams according to the second invention of the present application.

First, Figure 2 A shows the characters related to the cutout of the character ``hira''.
FIG. 3 is a plan view showing a state in which the face 10 is attached to a coarse seam I woven by weft and warp threads 1 and 2;

In this case, as shown in FIG.
(The adhesive can be replaced with adhesive as described above.

) The threads 1 and 2 are embedded in the layer and pasted.

In this case, it has been confirmed that if the adhesive or adhesive is the same or similar to the thermoplastic resin attached to the threads 1 and 2, the adhesion strength will be significantly improved as the two bond over time. It is being

In Figures B and C, the yarns 1 and 2 are shown fully embedded in the adhesive layer, but even if they are partially embedded as in Figure D, a considerable effect can be achieved.

In this case, it is desirable that half or more of the threads be embedded.

In short, it is extremely important that the adhesive or adhesive is not simply attached as a thread, but that it is embedded in the layer.

Next, FIG. 3A shows the adhesion of letters and faces to a coarse sheet according to the second invention.

Similarly, the character/face 10 with the character "Hira" cut out is pasted on a coarse sheet I made up of threads of 1°2, but in this example, a coarse sheet is attached to the back side of the character/face. As in the previous example, the adhesive 10a (or an adhesive may also be used) is applied to the back side of the letters/character faces through which the sheet-like material 20 is coated.

) is different in that it is bonded by crosslinking.

The sheet-like material 20 may be of the same size as the characters/fonts, for example, the same shape and size as the character "hira" as shown in FIG. It may be something that comes into contact with it.

A schematic diagram in that case is the third diagram. In this case, the characters
A sheet-like material is used which is joined to the circular edge of the font 10a.

Of course, even in the case of FIG. 3, it is necessary that the yarn 1.2 is embedded in the adhesive layer 10a as shown in FIG. This is the same as the case in FIG.

The sheet-like material 20 is usually coated with a pressure-sensitive adhesive or an adhesive on the surface opposite to the back surface of the letters/characters, but may not be coated with an adhesive.

The sheet-like material is preferably a woven fabric of polyester, vinylon, etc., particularly one in which the woven fabric is impregnated or coated with a synthetic resin.

In addition, various film-like materials and other sheet-like materials that are resistant to rain and dew and can be colored or colored may be used.

The present invention is based on the above-mentioned weaving, and since the coarse sheet is one in which the interlining yarns are sufficiently joined at the intersections in the weft and weft directions, there is no yarn deviation, etc., and therefore the characters are・The adhesion of the letters is ensured, and each thread of the coarse sheet is embedded in the adhesive or adhesive applied to the back of the letters and letters, so the adhesion strength is extremely high. Bonding force is also generated between the adhesive or adhesive and the thermoplastic resin attached to the yarn, so that an extremely good adhesion state is maintained over time.

Furthermore, when a sheet-like material is provided that is bonded to the pressure-sensitive adhesive or adhesive for the characters/faces through a coarse sheet, the two will be cross-linked, and the adhesion effect will be extremely significant.
