DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dyed glass fiber fabric, and more particularly to a glass fiber fabric used for the interior of railway cars, ships, aircraft, automobiles and the like.

[0002]

2. Description of the Related Art Interior materials for transportation such as railway vehicles, ships, aircraft, and automobiles (hereinafter referred to as "vehicle interior materials"), particularly under vehicle windows which are used by an unspecified number of passengers and are easily exposed to fire caused by smoking. A high degree of flame retardancy is required for the interior material for the waist. For this reason, completely incombustible materials such as glass fibers, metal plates, and tetrafluoroethylene resins are used for vehicle interior materials.

[0003]

The interior material formed by molding a metal plate does not have a sound absorbing property, has a cold touch, easily causes dew condensation, and easily generates mold due to the dew moisture. Therefore, the use of glass fiber cloth is conceivable. In fact, plain glass fiber fabrics must be used for vehicle interior materials requiring the above.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to obtain a beautifully non-combustible glass fiber fabric suitable for vehicle interior materials, which has a soft touch, does not cause dew condensation, has a printed pattern, and is beautiful.

[0005]

A vehicle interior material according to the present invention is made of a glass fiber fabric dyed with a raster, and has a laminate of a heat-fused fluorine resin film on its surface. Things.

[0006] The fluorine-based resin film includes ethylene fluoride resin film, ethylene fluoride resin film, ethylene fluoride resin film, ethylene fluoride resin film, vinylidene fluoride resin film,
A fluoroethylene-6-fluoropropylene copolymer resin film or the like is used, and among these, a tetrafluoroethylene resin film and a tetrafluoroethylene-6-fluoropropylene copolymer resin film are preferable. These fluorine resin films are:
The sheet is pre-heated by being superimposed on the glass fiber cloth, passed through a heated embossing roll at about 250 ° C., and pressed against the glass fiber cloth to be fused and integrated. The thickness of the fluororesin film is preferably 50 μm or less, which is と or less of the thickness of the glass fiber cloth, and generally 15 to 30 μm.

[0007] To obtain a glass fiber fabric dyed by a raster, (1) a glass fiber yarn is given a raster, heated and the raster is fired, and the dyed glass fiber yarn is woven by a loom or a knitting machine.・ The first method of knitting,
(2) A glass fiber yarn is given a raster, and the glass fiber yarn to which the raster is applied is woven and knitted by a loom or a knitting machine to form a glass fiber fabric, and the fabric is heated and the raster is fired. Any of the second method of (3) applying a raster to the glass fiber cloth, heating and firing the raster may be used. When exposed to the high-temperature atmosphere in which the raster is fired, the glass fiber yarns have a slight decrease in strength, making it difficult to weave and knit.Rasters that only adhere to the fiber surface without being fired are easily rubbed and fall off Therefore, the best method among these methods is the third method, and the next best method is the second method. It is preferable to use glass fibers having a thickness of 15 μm or less.

In the case of the first method described above, yarns other than glass fiber yarns dyed with a raster can be mixed. At this time, a required pattern is applied to the surface of the fabric by a patterning device such as jacquard or dobby.・ You can draw patterns. Of course, also in the case of the above-mentioned second method, a required pattern can be drawn on the surface of the fabric by jacquard or dobby, but in that case, the yarn other than the glass fiber yarn dyed by the raster may be used. Heat-resistant fibers such as glass fibers and carbon fibers are used. In the case of the third method, a glass fiber non-woven fabric can be used as the glass fiber cloth, and a raster is printed on the glass fiber cloth and heated and baked to draw a raster pattern or pattern on the surface of the glass fiber cloth. You can do it.

In order to bake the raster, heating may be performed at about 600 ° C. for about 10 minutes. The raster forms a transparent film that has been fired to form a color on the fiber surface, whereby the glass fiber (yarn / fabric) is dyed in a color corresponding to the composition of the raster. When printing the raster, it is preferable to apply a resin to the glass fiber cloth in advance and to perform the sealing, so that misalignment of the glass fiber cloth (misalignment of the cloth) is prevented, and the printing of the raster is performed. The shape becomes sharp. Note that the resin used for filling does not burn off the vehicle interior material because it burns and disappears during heating for firing the raster. Therefore, various resins can be used for filling.

[0010] In the present invention, "raster" means a paint containing metal oxide particles which is used in the field of ceramics for drawing and firing a picture or pattern on the surface of a porcelain, and includes silicate. In addition to metal oxides as compounds and coloring agents, general materials prepared by blending sticky agents such as turpentine oil, camphor white oil, sassafras oil, etc. with soda, potash, lead, etc. Commercially available ones can be used. However, a raster is mainly made of soda, potassium, lead, etc. as a solvent, regardless of its components, as long as it is baked to form a colored film on the surface of the glass fiber. You may. It should be noted that turpentine oil and other oils and resins blended as a tackifier burn and disappear when heated for baking the raster.

[0011]

Example: A glass fiber yarn of 67.5 tex is a warp, and a glass fiber yarn of 135 tex is a weft.
The warp density is 54 yarns / 25 mm, and the weft density is 30 yarns / 25 mm.
A glass acetate woven fabric having a basis weight of 337 g / m ² woven with a thickness of 25 mm was provided with a vinyl acetate-acrylic copolymer resin emulsion and sealed, and passed through a screen print machine to print a raster having the following composition. Through 6
The raster was baked by heating at 00 ° C for 7 minutes,
A μm-weight 54 g / m ² tetrafluoroethylene resin film is superimposed on the printing surface side, passed through a heated embossing roll at 250 ° C., pressed onto a glass fiber fabric, fused and integrated to form a vehicle interior material. I made it.

[0012] It was confirmed that light applied from the back side was transmitted at the printing portion of the raster, and the raster was fired and became transparent. The obtained vehicle interior material passed the flame retardancy test standard specified in the Airworthiness Examination Guideline Part 3 (airplane) and the nonflammability of the flammability standard of railway vehicle materials based on the Railway Business Act.

The glass fiber according to the present invention is dyed by a raster which develops a color when heated at an extremely high temperature unlike dyes, so that it is excellent in heat resistance and light fastness, and requires an inflammable binder and is opaque. It has a vivid luster because it is dyed on a raster that is fired regardless of the pigment that forms the conductive film and forms a transparent, completely non-combustible film.
It is very convenient as a material for interior materials.

Since the glass fiber fabric according to the present invention is mainly composed of glass fiber, it has much better sound absorbing and heat insulating properties than conventional products made of a metal plate, and has a soft feel and no dew condensation. Since the surface is coated with a tetrafluoroethylene resin film, the glass fibers do not fluff and have abrasion resistance and antifouling properties. The oil agent and the resin are burnt and vaporized in the course of sintering the raster component and disappear, and both are completely non-combustible because they are composed of completely non-combustible glass fiber, the raster and the fluororesin film.

The light-refractive index of the tetrafluoroethylene-based resin coating the surface is extremely low, and the printed pattern of the raster appears dark and clear. In particular, when the thickness is set to 20 to 30 μm, the glass fiber cloth is used. Undulation of the texture pattern appears clearly, and a splendid glass fiber fabric having a three-dimensional effect can be obtained. Therefore, the glass fiber fabric according to the present invention is very convenient for the interior of the seating under the window of the railway vehicle, which is easily seen by passengers, is easily contaminated by spilled food and drink, and is easily exposed to smoking fire.

The glass fiber fabric according to the present invention is completely nonflammable, and is suitable for ceiling and wall-covered floors of high-rise buildings, underground shopping centers, theaters and the like which require advanced fire prevention measures in addition to vehicle interior materials. It can also be used as a building interior material. Then, the fired raster becomes transparent, and thus, the printed portion of the raster becomes transparent, and the glass fiber fabric and the ethylene tetrafluoride resin film transmit light, so that the non-combustibility, light transmission and decorativeness are improved. It can also be used as a surface cover for lamp shades and other lighting fixtures, which are required, and can also be used as an electromagnetic wave shielding material or a filter. Both of these are commercially available, and the present invention can be easily carried out, so that the present invention has great industrial advantages.
