[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drapery interior wall and a drapery method.

[0002]

2. Description of the Related Art Interior construction methods for installing interior materials on walls include:
Adhesive is applied to the entire back surface of the interior material and the entire surface is adhered to the wall construction base, and the adhesive is applied to the periphery of the interior material or the periphery of the interior material is applied to the wall construction base without using an adhesive There is a fixed curtain setting method. In the former, that is, the whole-surface bonding method, the interior material is completely adhered to the construction base and does not float off after construction, but the cold feel of the construction base is felt on the interior material surface, surface dew condensation easily occurs, and a sound absorbing effect is expected. There are drawbacks such as not being performed. On the other hand, in the latter case, the drapery method, the underlaying paper is attached or not attached to the base of the construction, and the cushioning material such as white flannel or non-woven fabric is placed underneath. Since the interior material is floated over the entire surface of the construction base, the cold feel of the construction base is difficult to be transmitted to the surface, and the interior material is used in the whole surface bonding method such as surface condensation and low sound absorption effect. The disadvantages are eliminated. However, it is in such a state that it floats over the entire surface, and most of the interior materials made of fabric are mainly composed of cellulosic fiber which absorbs moisture and easily expands and contracts. It is easy to cause loose wrinkles on the surface of the installed interior material due to the change in temperature and humidity, and when the interior material is made of woven fabric, the fabric is misaligned or skewed, which makes it difficult to work. Furthermore, the cushioning material applied to the back surface of the interior material is bulged and rich in air permeability, and easily burns in the event of a fire. Therefore, even if the interior material itself has been subjected to flame-retardant processing, the back surface has a fire. It is easy to burn around, and it is not possible to construct a curtain-covered interior wall that passes the quasi-nonflammable standard prescribed in Article 1 of the Building Standards Law Enforcement Order.

[0003]

[Problem to be Solved by the Invention] The present inventor has applied a needle punching process to an interior material finished by laminating a backing paper on a woven fabric, and finely shred the laminated backing paper. The interior material is made flexible and the interior material is breathable to increase sound absorption.Furthermore, finely cut pieces of backing paper are used to finely connect warp and weft yarns to improve the shape stability of the interior material. The present invention has devised an interior material for curtain covering that does not bend and skew at the time of construction and discloses it in Japanese Utility Model Laid-Open No. 4-76813. However, in this prior invention, the surface of the interior material is fuzzed by the needle punching treatment, and the surface gloss inherent in the satin fabric is impaired in the case of using the fabric of the satin weave, so that it is applied to the interior material of the satin weave. Can not do. And, depending on the invention of the prior application, it is not possible to eliminate the misalignment or the skew curve generated in the woven fabric in the laminating process of the backing paper before the needle punching treatment, and the backing paper is a kind of cellulosic fiber. Since it is composed of pulp fibers, it is impossible to prevent loose wrinkles or expansion and contraction of the interior material due to changes in temperature and humidity after construction.
As a fire prevention measure, a thick glass fiber laminate was used as a cushioning material. However, since the glass fiber fragments are difficult to penetrate into the skin and work hard, and lack cushioning properties, they cannot be used for a drapery interior wall.

[0004]

[Purpose of the Invention] Accordingly, the present invention is based on the Building Standard Law Enforcement Ordinance
It passes the quasi-incombustible standard prescribed in the article, does not cause slack wrinkles or changes in expansion and contraction due to changes in temperature and humidity, and tries to cleanly decorate the interior fabric without ditching the cloth grain.

[0005]

According to the present invention, the cushioning material 20 is superimposed on the wall surface foundation 12, and the peripheral material is fixed on the cushioning material 20 without adhering the entire surface to the interior material 11. The heat-resistant temperature is 1100 ° C. or more and the thickness is 1 to
Bulk density of 0.1 to 0.
The ceramic fiber laminate having a thickness of 2 g / cm ³ and a thickness of 10 to 15 mm is used for the cushion material 20. The cushioning material 20 is fitted into the formwork assembled on the wall surface foundation 12, or is attached to the wall surface foundation 12 by nails, stapler needles, countersunk screws, tacks, or the like 21. A cloth such as a woven fabric, a knitted fabric, or a non-woven fabric is used for the interior material 11, but the heat-fusible resin composition 14 is not more than 30 g / m ^{2 in the} form of dots without forming a film-like continuous non-permeable film. Non-woven fabric 16 having synthetic fiber 15 having a basis weight of 60 g / m ² or less as a main material (total basis weight 90 g / m ^2).
g / m ² or less) or a basis weight 6 mainly composed of synthetic fibers.
A nonwoven fabric (16) mainly composed of inorganic fibers (15) having the same bulk density as a nonwoven fabric of 0 g / m ² or less is bonded to the back surface of the interior fabric 13 via the heat-fusible resin composition 14. It is preferable to form the interior material 11,
The cushioning material 20 is superposed on the cushioning material 20 and stretched, and the cushioning material 20 is superimposed on the cushioning material 20 and the peripheral edge is fixed without bonding the entire surface. The nonwoven fabric 16 is bonded to the interior fabric 13 by heating and pressing. At this time, the heat-fusible resin composition 14 is prevented from penetrating deeply into the interior fabric 13 beyond half the thickness of the warp 17 and the weft 18 constituting the interior fabric 13.

The first reason for using the nonwoven fabric 16 having a basis weight of 60 g / m ² or less is that in the nonwoven fabric 16 having a basis weight of 60 g / m ² or less, fine voids are finely distributed over the entire surface and the opposite side can be seen through. When the heat-fusible resin composition 14 is applied in a dot shape with an adhesion amount of 30 g / m ² or less to one surface thereof, and is laminated on the interior fabric 13 by heating and pressure bonding, the warp 17 and the weft 18 of the interior fabric 13 From the enclosed cloth 19 through the gap of the nonwoven fabric 16, the cloth 11
This is because air and moisture can permeate over the front and back surfaces, and the curtain cloth 11 does not impair the sound absorption characteristics of the cushioning material 20 provided thereunder, and dew condensation does not occur on the curtain cloth interior material 11. The second reason is that the texture 19 of the interior fabric 13
Between the warp 17 and the weft 18 which are orthogonal to each other,
Between the warps 17A and 17B and the weft 18
A and 18B are connected to the fibers 15 of the nonwoven fabric 16 extending in all directions, and the connecting fibers 15 are connected to the nonwoven fabric 16.
Is extremely thin with a basis weight of 60 g / m ² or less, so that it does not bend in the thickness direction of the interior fabric 13 and extends in parallel to the back surface of the fabric, connecting the columns and beams of the building. The warp 17 and the weft 18 are connected not in the thickness direction of the drapery interior material 11 but in the plane, such as a brace and a brace, so that the displacement of the warp 17 and the weft 18 and the skew curve of the cloth 19 are effective. It is because it is suppressed to. The third reason is the mass per unit area of 60 g / m ² or less ultrathin nonwoven 16, slight heat-fusible resin composition on the surface of 30 g / m ² or less and 14
Is applied in the form of dots, the applied heat-fusible resin composition 14 is interposed on the surface of the nonwoven fabric 16 as a lump protruding in the form of dots, and the nonwoven fabric 16 is overlaid on the interior fabric 13 and heat-pressed. In this case, the heat-fusible resin composition 1
This is because all of No. 4 closely adheres to the interior fabric 13 and the nonwoven fabric 16 is firmly bonded. For this reason, the nonwoven fabric 16
Has a thin and low weight, preferably 10 to 3
0 g / m ² , more preferably 20 to 25 g / m ²
It is recommended to use

In this respect, when a thick nonwoven fabric having a basis weight of more than 60 g / m ² is used, the thick nonwoven fabric closes the grain 19 of the interior fabric, and the interior fabric 13 is completely adhered to the cushioning material 30 of the underlay. It is not possible to bring out a soft and warm feel to the construction wall as a result, and the surface of a thick nonwoven fabric is fluffy, and the fibers of the surface fluff following the thickness direction of the nonwoven fabric are the warp 17 of the interior fabric 13 and the like. 20 g / m applied to the surface of the weft yarns 18 without the action of connecting them in a plane like a brace or a cross stick
The slight amount of the heat-fusible resin composition 14 of about ² is absorbed inside the nonwoven fabric and does not effectively act on the adhesion to the interior fabric 13, and delamination between the woven fabric and the nonwoven fabric or in-layer peeling inside the nonwoven fabric occurs. If a large amount of adhesive is applied to eliminate the inconvenience and the fibers of the nonwoven fabric are adhered to each other, the whole nonwoven fabric becomes like a backing paper, and the physical properties of the curtain-covered interior material 11 are changed to a thick nonwoven fabric. Dominated, on the other hand, curtain-covered interior material 1
1 tends to have loose wrinkles, making it impossible to achieve the intended purpose of the present invention.

Accordingly, in the nonwoven fabric 16, voids are finely distributed on the entire surface so that the opposite side can be seen through, fibers 15 extend in all directions in a plane, and the applied heat-fusible resin composition 14 It is necessary to use a material that is interposed on the surface of the nonwoven fabric as a lump protruding into the nonwoven fabric, and even if the basis weight changes somewhat depending on the specific gravity of the fibers 15 constituting the nonwoven fabric,
The nonwoven fabric 16 having a basis weight of 60 g / m ² or less satisfies these requirements. A preferred fiber as the fiber 15 constituting the nonwoven fabric is a polyester fiber. Therefore, the bulk density of the fiber of the nonwoven fabric is reduced to a basis weight of 60 g / m ^{2 of the} polyester fiber.
If the bulk density of the fibers of the following nonwoven fabric is the same, a nonwoven fabric that becomes an inorganic fiber such as glass fiber or carbon fiber can be used. In the present invention, the nonwoven fabric 16 mainly composed of synthetic fibers or inorganic fibers means that synthetic fibers or inorganic fibers occupy 50% by volume of the fibers constituting the nonwoven fabric 16, and therefore cellulose such as rayon, cotton and pulp. This means that a nonwoven fabric 16 in which some system fibers are used can be used. The reason for using the non-woven fabric 16 mainly composed of synthetic fibers or inorganic fibers is that even if the interior fabric 13 is made of cellulosic fiber that easily absorbs moisture and changes in expansion and contraction, the change in expansion and contraction of the non-woven fabric 16 can be prevented.
Therefore, the synthetic fibers or the inorganic fibers are 100% by volume.
It is recommended to use a non-woven fabric 16.

The heat-fusible resin composition 14 for bonding the interior fabric 13 and the non-woven fabric 16 is applied in a dot-like manner with a deposit amount of 30 g / m ² or less without forming a film-like continuous non-permeable film. The reason for this is that if it adheres to the back of the fabric in the form of a film, the stretchability of the interior fabric 13 is impaired and it becomes impossible to correct the skew or curve by pulling during construction, and for that purpose, the basis weight of the interior fabric is reduced. It is to be applied at about 10 g / m ² which is not more than 30% by weight and not more than 50% by weight of the basis weight of the nonwoven fabric, and the dot (14) to be attached has a size of 0.5 to 2 mm (about 1 mm) in diameter and 1 cm ^It is preferable to uniformly distribute on the surface of the nonwoven fabric 16 with a distribution density of four or more per two.

That is, in the present invention, the nonwoven fabric 16 prevents the interior fabric 13 from becoming loose and wrinkled due to moisture, imparts shape stability to the interior fabric 13, and simultaneously reduces the skew curve of the fabric found at the time of construction by using the interior fabric 13 as a warp. It is necessary to ensure the elasticity of the interior fabric 13 necessary for straightening and correcting the tension along the weft 17 and the weft 18. In the present invention is from this point of view, to use a basis weight of 100 to 500 g / m ² The interior fabric 13, on the back side over the entire surface, having a basis weight of 60 g / m ² or less of the nonwoven fabric 16, film-shaped on one side Lamination is performed via the heat-fusible resin composition 14 which is provided in a dot shape with an adhesion amount of 30 g / m ² or less without forming a continuous non-permeable film.

In the present invention, the reason why a ceramic fiber laminate having a bulk density of 0.1 to 0.2 g / cm ³ and a thickness of 10 to 15 mm in which ceramic fibers having a heat resistant temperature of 1100 ° C. or more are entangled with the cushioning material 20 is used. , Fire is 1100 ℃
Furniture furnishings and buildings spread out at the following combustion temperatures and the glass melts at 700 ° C. Therefore, heat-resistant temperature 1
The cushion material 20 having a temperature of 100 ° C. or more withstands the burning temperature at the time of fire and prevents the spread of the fire to the wall surface foundation 12. However, when the bulk density is less than 0.1 g / cm ³ or the thickness is less than 10 mm, flame or hot air is transmitted from the gap between the fibers to the wall surface foundation 12 and is not sufficient to prevent the spread of fire. If the bulk density exceeds 0.2 g / cm ³ , the ceramic fiber material itself is a mineral having a high specific gravity and a high thermal conductivity. This is because heat is easily transmitted.

The thickness of the ceramic fiber is made extremely thin, 1 to 5 μm, so that heat is easily radiated from the surface of the ceramic fiber and the heat insulating effect of the cushion material 20 is enhanced. At the same time, the thickness is 1-5μ
When the thickness is as small as m, the ceramic fibers increase in flexibility and are hard to break, and the compressive elastic recovery force of the cushioning material 20 is also remarkably improved, so that broken ceramic fiber fragments pierce the skin and hinder construction work. No more.
And again, if you make the ceramic fiber extra fine like that,
Even if the curtain-covered interior material 11 and the cushion material 20 are temporarily bonded at the interior material manufacturing plant before the application to the wall surface foundation 12, the heat-fusible resin composition 14 has fine fluff on the surface of the cushion material 20. Since it looks good to be fused to, it is possible to easily peel the curtain-covered interior material 11 from the cushioning material 20 by lightly rubbing the surface of the curtain-covered interior material 11 after construction,
This is convenient for transporting them, and is also advantageous because the number of work steps at the interior construction site is reduced.

EXAMPLES basis weight was subjected to a flame retardant 72 g / ^{m 2} applied to flame retarding rayon textile fabric 13 of 288 g / ^{m 2.} Next, a nonwoven fabric 16 having a basis weight of 25 g / m ² made of polyester fiber is applied to the woven fabric 13, and a hot melt adhesive 14 is applied to the surface of the woven fabric 13 by a mesh roll in an amount of 15 g / m ^{2 in} a dot shape of 1 mm in diameter. Then, they were heat-pressed to produce a curtain-covered interior material 11. Next, the periphery of the cushion material 20 having a bulk density of 0.13 g / cm ³ and a thickness of 12.5 mm in which ceramic fibers having a heat-resistant temperature of 1260 ° C. or more are entangled is fixed to the construction base 12 with an adhesive 22 and the studs 21 are driven. Attachment, the drapery interior material 11 is superimposed on the cushion material 20, an adhesive 23 is applied to the periphery thereof, tension is applied up and down and left and right to eliminate the skew curve of the cloth, and the periphery 24 is adhered to the drapery.

[0021]

As described above, according to the present invention, the curtain-covered interior wall 25 is made up of the interior cloth 13 and the non-woven fabric 16 constituting it.
Since both the cushion member 20 and the cushion member 20 have air permeability, they do not cause surface dew condensation and exhibit an excellent sound absorbing effect. Since the ceramic fiber constituting the cushion material 20 is very thin, having a thickness of 1 to 5 μm, and is very flexible and hard to break, the cushion material 2
A value of 0 is high in compressive elastic recovery, so that broken ceramic fiber fragments do not penetrate the skin and do not hinder the work. Since the cushioning material 20 having a heat resistance temperature higher than the combustion temperature at the time of fire and having a low heat conductivity without passing through flames or hot air is laminated on the back surface of the drapery interior material 11, the drapery interior is applied. The wall 25 passes the quasi-nonflammable standard prescribed in Article 1 of the Building Standards Law Enforcement Ordinance, and renders the wall construction base 12 flame resistant to such an extent that it does not burn off in the event of a fire. When a skew curve of a cloth is found on the surface of the interior fabric 13 at the time of construction, it can be corrected by tensioning the warp 17 and the weft 18. The interior fabric 13 is excellent in dimensional stability and shape stability without generating loose wrinkles on the surface due to changes in temperature and humidity after construction, and can be neatly constructed without shape collapse. Since the non-woven fabric 16 is an ultra-thin material having a basis weight of 60 g / m ² or less, the use of the non-woven fabric 16 does not increase the cost of the drapery interior material 11, and the drapery interior material 11 is simply formed by heat-pressing it. Is obtained.
