Therefore, the “fabric” referred to in the present application is a soft base material that can be used in any design, from fashion miscellaneous goods to outerwear to interiors, and is used as a concept including a material that can be bonded to a resin material. . Therefore, the fabric 1 is not limited to woven fabric, leather, artificial leather, and synthetic leather, but also includes a laminated material of wood, paper, and felt.

In interior design, it is a material used as a stained glass, such as a soft stained glass, which has no visual risk, such as a soft stained glass. As an example of use, when used in lamp shades, it is safer because it does not break compared to conventional lamp shades made of real glass or acrylic plate, and can be used for various interior decoration items etc. Material.

The cloth 1 shown in FIG. 1 has a predetermined thickness in the depth direction of the drawing, and a plurality of resin portions 2 are buried in the thickness, and the surface of each resin portion 2 is processed into a smooth surface. FIG. 1 shows a configuration example in which a geometric pattern is drawn by a resin, but the configuration of the present invention is not limited by the arrangement and range of the resin portion 2. That is, the resin portion 2 can be formed in any shape and size and in any arrangement, and is not limited to a geometric pattern. it can.

FIG. 2 is a sectional view of a main part of the cloth 1 having the resin portion 2. The resin portion 2 is filled in each of the holes 1a punched in the thickness direction of the cloth 1, and is welded to the cut surface 1b which is the inner surface of the hole of the cloth 1. This resin part 2
As a suitable material, a soft plastic material made of a polymer material having carbon as a main chain component, or a silicon resin made of a polymer material having silicon and oxygen as a main chain component is suitable. This polymer material, whether crystalline or non-crystalline, has an elasticity close to that of the dough 1 to be used and, when cured, a dough 1
Use the one with the adhesive property to adhere to.

As the plastic material, for example, an acrylic resin can be used. The general formula of methyl methacrylate resin as this kind of acrylic resin is shown below.

Embedded image

A water-based acrylic resin-based filler (for example, Asahi Pen Co., Ltd.) is commercially available, which is not transparent but has elasticity and adhesiveness that can follow the deformation of the cloth 1, and is decorated as an art material. A paint can be applied to the surface 2a. However, it may be difficult to obtain transparency. Transparency is obtained by using silicon RTV rubber (Room Te)
This is a colorless type of “vulcanizing (room temperature cured rubber)” or a case where silicon is filled in advance. If the decorative surface 2a is made of a resin that can be colored in this way, the decorative surface 2a can be shaded or painted with an airbrush, or each decorative surface 2a can be colored differently.
A mosaic pattern can be applied to the fabric 1.

According to the colored and transparent resin portion 2 which is replaced in a mosaic shape and penetrates the cloth 1, a design like a stained glass which transmits transparent light can be constituted, and conventional leather, artificial leather, synthetic Soft fabric 1 such as leather
Can provide an unprecedented aesthetic.
Light transmission and transparency like stained glass are esthetics from a viewpoint that could not be considered with conventional fabrics. Resin part 2
Is not limited to the acrylic resin, but vinyl chloride, polyurethane resin, or the like may be used. The urethane resin is a liquid adapt 60L (trade name), an adapt 80L (trade name), or a putty-like adapt 80, which is a patented product manufactured by Kokusai Chemical Co., Ltd., which is elastic and has good transparency and adhesiveness.
P (product name) is used. These products contain tolylene diisocyanate in an amount of 2% (weight percent)
It is blended in.

The silicon resin may be a silicone RTV having flexibility, transparency and adhesiveness in a cured state.
Rubber (Room Temperature Vulca)
(Nizing: rubber cured at room temperature) can be used.
This is the formula

Embedded image (Where R is an organic atomic group having an arbitrary number of carbon atoms) is formed by kneading silica sand as a filler into silicone oil, and coloring is possible by adding a pigment.
This kind of silicones is excellent in flexibility and mechanical stickiness, and has good followability to the fabric 1. With these expression methods, a stained glass-like design can be formed, and an aesthetic property utilizing light transmission that is completely different from the aesthetic property of a conventional fabric can be provided.

Although a flexible material is used for the resin portion 2 in the present embodiment, the degree of elasticity of the resin portion 2 depends on the functionality of the cloth 1, that is, the flexibility. , Elasticity, and the like, and the required adhesive strength varies depending on the thickness of the cloth 1 and the range of replacement with the resin portion 2. For example, a hard resin portion 2 can be used for a durable thick leather constituting a handbag, and the present invention can be applied to a thin woven fabric or the like as long as each resin portion 2 is limited to a small range.

Next, a method of manufacturing the fabric 1 decorated with resin will be described with reference to FIGS. 3A and 3B are diagrams showing a punching process of the dough 1 in the present embodiment. FIG. 3A is a cross-sectional view of the dough before punching, and FIG. First, the arrangement and shape of the resin portion 2 are determined, and a punch 3 according to the dimensions is prepared. As shown in FIG.
The dough 1 is placed on a worktable 5 whose posture is stable, and thin sheet-shaped masking 4 is applied to both upper and lower surfaces. However, the masking 4 may be only the upper surface or the lower surface.
By providing the masking 4 not only on the upper surface but also on the lower surface, even if the resin oozes out, it is possible to protect the surface from being stained with the resin.

The masking 4 uses a film having both adhesiveness and releasability to the fabric 1 and releasable to resin. In this example, a polyethylene film (trade name King Film of Holpain Art Materials Co., Ltd.) coated with an acrylic adhesive was used. In the illustrated example, only one punch 3 is used. However, in practice, a punch having a plurality of blades for cutting out a mosaic pattern may be used to punch a plurality of locations at once. Various punching methods using laser light or the like other than punching with a punch can also be used.

As shown in FIG. 3 (b), the fabric 1 has a lower surface in close contact with a worktable 5 and a masking 4 provided on both sides.
The sheet is punched in the thickness direction by the punch 3. Punch 3
The cloth 1 having a predetermined shape is punched together with the masking 4 on both sides to form a cavity 1c as a notch. Since the masking process has been performed before this punching step, the masking 4 is cut neatly along the periphery of the hole 1a.
Thereby, not only the surface of the cloth except the hole 1a is protected by the remaining masking 4, but also the boundary with the resin portion 2 in the hole 1a to be formed later can be clearly formed.

The work table 5 is desirably made of a releasable material. Examples of the releasable material include Duracon, Teflon, polyethylene, polypropylene, natural rubber, and neoprene rubber. If the worktable is made of a moldable material, there is no problem with the work, but if the worktable is not made of a releasable material, the resin may adhere to the worktable. Should be stuck on the workbench. A polyethylene film (trade name: Holbein) is used as a release film to be attached to a work table. Further, since the resin may flow between the cloth 1 and the work table 5 and the surface of the cloth 1 in contact with the work table may be stained, it is desirable to cover the cloth 1 with a film or the like having a releasing property in advance.

When the fabric is thin, a lining can be attached as reinforcement. The thickness of the dough is 1.5
A sufficient adhesive strength that the resin portion does not fall off can be obtained if it is about 5. However, in the case of a thin cloth less than that, there is a sufficient area between the cloth and the resin section because the area of the cut surface 1b serving as the bonding surface is small. It cannot provide adhesive strength. Therefore, as a method to secure the surface where the resin adheres to the fabric and increase the adhesive strength, a liner larger than the hole is attached to the periphery of the back side of the perforated hole along the bottom of the hole, and the bottom is attached to the hole. A method of injecting a fluid resin material from the nozzle 6 into the hole provided at the bottom is also conceivable. As a result, the resin portion having increased adhesive strength does not fall off the fabric. In addition, since the resin may change in volume in the hardened state and may swell, it is desirable that the resin is lightly pressed from above by a flat pressing member until the resin is hardened.
This makes it possible to finish the resin portion of the surface to a mirror surface and to make the surface uniform.

FIG. 4 is a view showing a molding process of the resin portion 2.
FIG. 3A shows the state of resin filling, and FIG. 3B shows the decorative surface 2a.
FIG. 4C is a cross-sectional view of the cloth after the masking 4 has been removed. As shown in FIG. 4 (a), the cut surface 1b
A resin material having fluidity at room temperature is injected from the nozzle 6 into the cavity 1c surrounded by the circle, and is cured. In the case of the silicon RTV rubber, the surface starts to harden in 10 minutes at room temperature, and hardens after 24 hours. Due to the curing treatment at this time, the fluid resin becomes the cut surface 1 of the cloth 1.
b, and adheres so as to follow the deformation of the fabric 1. In particular, a resin that is partially immersed in the cloth 1 and hardens is cured inward from the cut surface 1b of the cloth 1 and further impregnated into the fibers of the cloth 1. If there is an adhesive property by such an anchoring effect, the resin part 2 is firmly bonded to the cloth 1.

Next, as shown in FIG.
Is removed from the worktable 5 and the masking 4 is peeled off. In this embodiment, a releasable worktable is required. As shown in FIG. 4 (c), in a state where the masking 4 on both sides is peeled off, the dough firmly holds the resin material 2 within the thickness and exposes the decorative surface 2a along the surface of the dough. Part 2 is completed. The surface grounded to the work table 5 is used as the surface of the dough. This is because it is suitable for accurately matching the surface of the resin material 2 with the surface of the cloth, and can be used without adding a finishing touch to the decorative surface. However, which surface to use as the surface of the fabric is a matter of choice, and it is free to use either surface as the surface for convenience of use.

Although omitted in this embodiment, the masking 4 may be provided only on one side. Instead of using the worktable 5, one surface may be masked after punching, and a resin material may be injected from the other surface. Further, the resin material to be injected is described as a thermoplastic resin such as a silicone resin which is cured by being left at room temperature. However, the resin material is not limited to this, and a thermosetting resin which is cured by mixing a curing agent may be used.

[0027]

As described above, the decorative fabric using the resin of the present invention comprises a fabric, a resin portion provided in the fabric and made of a polymer substance having carbon or silicon oxide as a main chain component, Since the resin portion is bonded to the fabric so as to leave a decorative surface exposed near the surface of the fabric,
By combining resin parts having different textures and the like into cloths such as leather, artificial leather, and synthetic leather with an arbitrary shape size and arrangement, it is possible to provide a new design / decoration technique for the cloths. . Fabrics with such textures are unique not only in Japan but also overseas.

According to the structure in which the resin portion is made of silicone rubber having elasticity capable of following the deformation of the fabric to which the resin portion is adhered, the resin portion does not lose functionality such as elasticity of the fabric. If silicone rubber is used, aesthetics can be pursued by molding a transparent and smooth decorative surface or the like. Further, since silicon rubber does not contain chlorine, no dioxin is generated even if it is incinerated.

Further, according to the configuration in which the resin portion is an acrylic resin having elasticity capable of following the deformation of the cloth to which the resin portion adheres, it is particularly easy to color the decorative surface of the resin portion.

In the method for producing a dough of the present invention, a cutout having a predetermined shape is provided in the dough, and the cutout is filled with a fluid resin material made of a polymer substance having carbon or silicon oxide as a main chain component, and cured. After processing, the exposed decorative surface of the resin part is processed, so that a new fabric design and decoration method can be provided by replacing a part of the fabric with resin. The resin part can be satisfactorily adhered to the fabric by the anchoring effect.

Further, in the above-mentioned manufacturing method, masking is performed on both surfaces or at least one surface of the dough, and the masked dough is punched out of the masking surface in a predetermined shape, and the above-mentioned blank is cut between cut surfaces of the punched dough. According to the method of removing the masking after filling the fluid resin material and curing it and processing the exposed decorative surface of the resin portion, it is possible to provide a mosaic-shaped notch only by punching the fabric. In particular, since the resin portion is located between the cut surfaces penetrating the cloth, the resin portion can be made transparent and a stained glass-like design or the like can be applied. Furthermore, the masking does not cause excess resin to adhere to the surface of the fabric during work and prevent the other surface from being stained during processing of the decorative surface, and particularly facilitates processing such as mirror finishing and coloring of the decorative surface. It is.
