DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth wall covering used by adhering to a wall surface, a ceiling surface, a partition surface such as a partition, a furniture surface, and the like.

[0002]

2. Description of the Related Art Cloth wall upholstery in which a backing paper is pasted on the back side of a fabric is more easily soiled than the one whose surface is made of plastic such as PVC wall upholstery, and a plastic film is pasted on the surface of the fabric. It is desirable to finish it.

[0003]

When a plastic film is attached to the surface of the cloth, there is a method of passing it through an embossing roll as a method of forming fine irregularities according to the grain of the cloth on the surface of the plastic film. Only the unevenness thus provided is transferred to the plastic film, and it is impossible to form fine unevenness on the surface of the plastic film like a cloth.

The applicant of the present application sucks the back surface of the cloth to which the plastic film is attached to bring the inside of the cloth into a vacuum state, and the plastic film is brought into close contact with the surface of the cloth to form fine irregularities according to the grain of the cloth on the surface of the plastic film. A method of applying the adhesive is invented and disclosed in Japanese Patent Application No. 3-259623. However, in the method according to the invention of this prior application, even if an attempt is made to back the backing paper to the cloth laminated with the plastic film on the surface, the cloth surface is covered with the plastic film, and the moisture in the adhesive applied to the backing paper is Since it is difficult to evaporate, it is practically impossible to line the backing paper with the adhesive on the fabric thus laminated with the plastic film. Therefore, repeated plastic film on the surface after attaching the backing sheet, a method of adhering the plastic film to the fabric by suction from the surface of the backing sheet but also think, backing paper breathability little substantially non Since it is breathable, such a method cannot be implemented in practice.

[0005]

According to the present invention, a fine unevenness (24) corresponding to a stitch 24 of a cloth is formed on a plastic film surface 13 of a cloth wall upholstery 14 having a backing paper 11, a cloth 12 and a plastic film 13 bonded together. ) Is intended to be given.

That is, according to the present invention, a cloth wall covering 14 in which a backing paper 11, a cloth 12 and a plastic film 13 are laminated in order.
In the process of forming a sheet, the backing paper 11 laminated with the fabric 12 has 0.01 vent holes 15 reaching the fabric 12 / c.
m ² or more open over the entire surface with perforations density, the plastic film 13 and a heated state in a state in which the backing sheet 11 and the fabric 12 and the plastic film 13 are overlapped, aspirated fabric internal air 16 from the vent holes 15 of the backing paper 11 at the same time A vacuum state between the backing paper 11 and the plastic film 13 so that the plastic film 13 is suction-adhered to the cloth 12, and by doing so, the cloth 2 of the cloth 12
The gist is that fine irregularities (24) corresponding to No. 4 are attached to the plastic film surface 13.

The cloth 12 and the backing paper 11 are laminated on the surface of the backing paper 11 on which the adhesive 26 is applied, and passed through a heat dryer to be bonded.

The reason for providing the ventilation holes 15 in the backing paper 11 is as follows.
The backing paper 11 is provided with air permeability by the ventilation holes 15, and the air 16 inside the cloth is sucked out from the ventilation holes 15 to create a vacuum state between the backing paper 11 and the plastic film 13.
This is because the plastic film 13 is suction-adhered to the cloth 12 so that fine irregularities corresponding to the texture 24 can be formed on the plastic film surface 13.

If the plastic film 13 has a heat-fusible property, the plastic film 13 is superposed on the cloth 12 and passed through a heating device 17 to be bonded. If the plastic film 13 does not have a heat-fusible property, the adhesive material 27 is used. It is stuck to the fabric 12 via.

The adhesive 27 may be an adhesive type prepared by viscously preparing a resin composition, or a binder film type formed by molding a heat-fusible resin composition into a film. it may also be there rather than, or in addition, have a heat-fusible
The heat-fusible resin composition is coated on the surface of the film.
It may be a laminated type. Adhesion
If the material 27 is of the adhesive type, plast
A few μ to 20 μ in front of the attachment surface of the photo film 13
I will coat it later. Constituting those adhesive materials 27
The vinyl acetate-based resin composition and the heat-fusible resin composition
Resin, polyurethane resin, polyester resin, etc. are used.
Used.

The plastic film 13 is attached in order to prevent loosening and dirt of the cloth 12, but if it is too thick, it is difficult to form irregularities along the stitches 24 and the gloss and texture peculiar to the cloth are impaired. Its thickness is
In the case of bonding with the adhesive 27, the thickness of the adhesive 27 is 300 μm or less, and generally 5 to 100 μm.
And preferably 5 to 30 μm. In that case, if the fabric 12 is coarsely woven or knitted with thick yarns such as Donglos, the thickness of the plastic film 13 depends on the yarns 28 forming the fabric 12.
The thickness of the thickest yarn among 29 may be less than or equal to one-third of the thickness of the yarn, and generally about one-tenth to one-fifth.

Various materials can be used for the plastic film 13, and in particular, the cloth 24 is provided on the surface thereof.
If you want to clearly show the irregularities along the edges, use a polyurethane type, and if you want to prevent discoloration of the fabric 12 and give it weather resistance, a fluorine type, preferably a vinylidene fluoride type In order to prevent the fabric 12 from unraveling at the cut edge of the cloth wall upholstery 14, an ethylene / vinyl copolymer system such as ethylene / vinyl acetate copolymer or ethylene / vinyl alcohol copolymer , Or polymethy
It is recommended to use a rumethacrylate type .

As described above, the ventilation hole 15 is opened to give the backing paper 11 ventilation, and therefore the ventilation hole 1 is provided.
It is preferable that the perforation density of 5 is large, but if it is too large, the construction adhesive applied to the back surface at the time of construction penetrates the backing paper 11 and oozes out to the cloth 12, so the backing paper 11 is backed on the cloth 12. The meaning of doing it will disappear. Of course, even if the ventilation hole 15 has a low perforation density, if the hole diameter (size) is large, the construction glue will soak into the fabric 12 from there. Considering these points, the vent hole 15
Of 0.1 to 0.6 mm, the opening area of the ventilation holes 15 is 0.03 to 0.4 mm ² , and the perforation density is 0.
It is preferable to set it to 3 to 5 pieces / cm ² , and if this is done, generally good results can be obtained.

The ventilation hole 15 can be formed by a pin having a thickness of about 0.5 mm, such as a spike roll 30 or a needle punching felt machine. However, when the plastic film 13 is laminated on the fabric 12, the ventilation hole 15 is formed. Is to open the spike roll 30 by pressing it against the backing paper 11. In this case, the pin densities and the lengths of the pins are determined so that the pins of the spike roll 30 do not stick into the plastic film 13. The pressing force of 30 is adjusted.

In order to bring the plastic film 13 into a heated state and suck out the air 16 inside the cloth from the ventilation holes 15 of the backing paper 11 so that the plastic film 13 is suction-adhered to the cloth 12, the backing paper 11, the cloth 12 and the plastic film 13 are made. The laminated body 19 in which the
