[Industrial Application Field] The present invention relates to a fireproof fiber cloth suitable for a fire blocking layer of an aircraft seat cushion. [Prior Art] Fire-blocking layers that have been proposed so far for use as an intermediate layer between the front upholstery of aircraft seat cushions and flame-retardant urethane foam have shown remarkable flame resistance. Polybenzimidazole fiber [trade name PBI], meta aromatic polyamide fiber [trade name Konex (registered trademark), Nomex (registered trademark)] and para aromatic polyamide fiber [aramid fiber, trade name Kevlar (registered trademark)] and other synthetic fibers, such as carbonized fiber [trade name: Pyromex (registered trademark)]. However, compared to those made of natural fibers, these synthetic fibers have higher raw material costs and lack hygroscopicity, so they are inevitably inferior in comfort such as sitting comfort. Therefore, from the standpoint of heat insulation, cost, and comfort, we mixed Zapro (registered trademark) wool (hereinafter referred to as flame-retardant treated wool), which is made by treating wool with metal complex salts of titanium or zirconium, with glass fiber, and added There have also been proposals that include aluminum foil attached and flame-retardant wool mixed with polybenzimidazole fibers or carbonized fibers. [Problem to be solved by the invention] Aircraft seat cushions must be able to withstand the rigorous FAA kerosene burner test (FAR.25853C), but it goes without saying that economic efficiency must also be considered. . Polybenzimidazole fibers that exhibit remarkable fire retardant properties are very expensive, so products containing this fiber as a component have problems in terms of economic efficiency. Aromatic polyamide fibers are also relatively expensive, although not as expensive as polybenzimidazole fibers, so products containing this as the main component are still economically problematic. Carbonized fibers and glass fibers have no problem in terms of price, but they have a problem in that they are not easy to process compared to other fibers. In addition, those with aluminum foil attached thereto have problems in that they are stiff, impair comfort, and generate unpleasant sounds when used. The present invention has been made in order to solve the above problems, and its purpose is to provide a fabric that is comfortable to wear or use, is relatively inexpensive and economical, and is also an excellent fiber fabric. It is an object of the present invention to provide a fiber cloth having fire retardant properties and which can also be used as a fire blocking layer constituting an aircraft seat cushion. [Means for Solving the Problems] In order to achieve the above object, the fiber cloth of the present invention contains 40 to 70% by weight of flame-retardant wool, and the remainder consists of phenolic resin fibers and aromatic polyamide fibers. It is characterized by The fiber cloth may be felt or a woven cloth, but in the case of a woven cloth, it is desirable to fill the voids between the yarns by relaxing or shrinking. Here, the reason why flame-retardant treated wool is mixed is that before exposure to flame, that is, during normal use, the flame-retardant treated wool has good texture and wearability as a natural fiber.
The aim is to take advantage of the ability of fire-retardant wool to form a bulky, heat-insulating carbonized layer when exposed to flame. Flame-retardant treated wool is wool treated with titanium or zirconium metal complex salts, and has flame-retardant properties and low smoke-emitting properties, and does not melt even when exposed to flames, producing a carbonized layer. , hygroscopic,
The temperature control function, heat retention, texture, etc. are maintained with almost no loss. Furthermore, it is economical because it is significantly cheaper than synthetic resins that exhibit remarkable fire and heat resistance properties, such as polybenzimidazole fibers and para-aromatic polyamide fibers. If the amount of flame-retardant wool mixed in is less than 40%, the comfort during normal use and the heat insulation property when exposed to flame will decrease.
is the lower limit of the contamination rate. On the other hand, flame-retardant treated wool is 70
If it is mixed with more than 70%, there is a risk that it will not pass the FAA kerosene burner test mentioned earlier.
is the upper limit. The reason for mixing phenolic resin fibers is that although they have a high carbon content during normal use, they do not have problems such as breakage or staining unlike carbon fibers, and exhibit relatively good fiber properties, and when exposed to flame. produces less smoke and gas, and is made into carbon fiber (carbonization rate approximately 80%) without dimensional changes, and retains a flame-retardant carbonized wool layer that is bulky, has no directionality, and is relatively easily broken by external forces. It's about doing. The amount of contamination
If it is less than 15%, the effect of protecting the carbonized layer of flame-retardant wool cannot be expected, so the lower limit is set at 15%.
However, if it exceeds 40%, there is a risk of puncturing (oxidation heat generation) characteristic of phenolic resin fibers, and the light fastness will also decrease significantly.
The upper limit is 40%. The reason for mixing aromatic polyamide fibers is to compensate for the decrease in strength and yarn properties that accompanies the mixing of phenolic resin fibers during normal use, and to obtain sufficient strength and abrasion resistance. The objective is to protect the flame-retardant carbonized wool layer as a carbonized fiber that does not change in size and has relatively good shape stability like resin fibers. If the mixed amount is less than 15%, sufficient strength and wear resistance cannot be obtained, so 15% is set as the lower limit. However, aromatic polyamide fibers are more expensive than the other two, and the heat resistance of carbon fibers produced when exposed to flame is inferior to that of phenolic resin fibers, so the upper limit is set at 30%. Note that meta-type aromatic polyamide fibers have lower heat resistance than para-type fibers, and also shrink when exposed to flame, so when used in the fire-blocking layer of a sheet cushion, the shape becomes stable when exposed to flame. The heat resistance is poorer than that of the para-type, and in some cases there may be more cleavage or gaps between the fibers, which may cause the molten urethane inside to drip. Therefore, it is desirable to use para-type aromatic polyamide fibers. [Function] Since the fire-retardant fiber cloth of the present invention is a composite material consisting of flame-retardant treated wool, phenolic resin fibers, and aromatic polyamide fibers, due to the mixing action, the fabric is more susceptible to dimensional changes and deformation than each fiber alone. Less is. During normal use, the fiber fabric of the present invention contains 70 to 40% of flame-retardant wool as a natural fiber, so it is very comfortable to wear or sit on.
In addition, it contains 15-30% strong aromatic polyamide fibers, so it has sufficient strength and wear resistance. When exposed to flame, all of the mixed fibers have low smoke emitting properties and generate only a small amount of gas, and the fibers are carbonized without being melted by flame exposure, resulting in less overall weight loss. The phenolic resin fibers and aromatic polyamide fibers attached to the flame-retardant wool generate carbonized fibers that capture and protect the bulky carbonized layer of the flame-retardant wool, which has excellent heat-insulating properties. It stays together and doesn't fall apart. Since the carbonized layer of flame-retardant wool is relatively thick, it is difficult for the molten urethane foam inside to penetrate through the fire-retardant fiber cloth. Therefore, dripping of molten urethane foam is reduced. [Effects of the Invention] Since the fire-retardant fiber cloth of the present invention is mainly composed of flame-retardant treated wool that retains the characteristics of natural fibers, it is easier to wear and feel when used than conventional cloths whose main component is synthetic fibers. Good, necessary strength and abrasion resistance are obtained by flame-retardant wool, which is further reinforced by aromatic polyamide fibers mixed in at 15-30%. Furthermore, since flame-retardant treated wool is relatively inexpensive compared to other heat-resistant fibers, it is economically superior. When flame-retardant treated wool is exposed to flame, it forms a bulky, non-directional carbonized layer with excellent heat-insulating properties, but on the other hand,
Relatively fragile to external forces. However, because the carbonized layer is protected by phenolic resin fibers that produce carbon fibers that do not deform when exposed to flame, the fiber fabric does not lose its shape or tear, and has excellent fire protection properties that can withstand the rigorous FAA kerosene burner test. has. [Example] The fiber cloth of the present invention will be explained based on an example.
First, flame-retardant wool obtained by treating wool with a complex salt compound of titanium or zirconium, a phenolic resin fiber with a 3-denier fiber length of 50 to 70 mm [trade name Kynol (registered trademark)], and a 1.5-denier cut length 2 Para-type aromatic polyamide fiber [trade name Kevlar (registered trademark) 29] of 1.5 inches is mixed and spun by worsted spinning or wool spinning to produce flame-retardant wool.
Two types of blended yarns were made: 50% (phenolic resin fiber 30%, para-type aromatic polyamide fiber 20%) and flame-retardant treated wool 60% (phenolic resin fiber 20%, para-type aromatic polyamide fiber 20%). A portion of the 50% flame-retardant wool blend yarn was twisted with 100-denier glass filaments. Each blended yarn was woven and subjected to a fulling process in the organizing process. In addition, a part of the flame-retardant treated wool 50% blend yarn fabric and the flame-retardant treated wool 50% glass fiber filament blend intertwisted yarn fabric was coated with a heat-resistant resin [trade name: PyroKeep (registered trademark)] on the back side. In this way, four types of test cloths were created. These test fabrics are mainly made of flame-retardant wool, so they have a good texture and are comfortable to use. However, since it contains a considerable amount of extremely dye-resistant heat-resistant phenolic resin fibers and para-type aromatic polyamide fibers, it is unsuitable for outer fabrics, but fire blocking is used for linings, especially under aircraft seat upholstery. As a layer, it can be said to be optimal not only in terms of comfort, wear resistance, and strength, but also in terms of fire protection performance. These test fabrics are coated with low smoke flame retardant wool 100%
