Description of the Related Art Needle felt used for the above-mentioned various applications is required to have properties such as heat resistance, bending resistance, abrasion resistance, light weight, soft cushioning property and surface smoothness. Therefore, conventional needle felts are mainly made of aramid fiber, carbon fiber, and oxidized fiber, and are made of inorganic fiber such as glass fiber, alumina fiber, silicon carbide fiber, inorganic whisker, steel slag fiber, aluminum and stainless steel fiber. And one or more of the above metal fibers are mixed. The heat resistant temperature in the air atmosphere is about 400 ° C.

使い勝手が悪い。However, the aramid fiber, carbon fiber, and oxidized fiber, which are the main materials of the needle felt, are very expensive, so that there is a problem that the felt product becomes expensive. Also, especially when using aramid fiber,
Deterioration and abrasion occur in a high-temperature atmosphere such as 400 ° C., so that when used as a pad material in a glass factory or an aluminum factory, it is necessary to replace it at an early stage, which is inconvenient.

It has heat resistance to withstand temperatures of 200 ° C. or more.
However, these fibers are very short fibers having a length of about 0.5 to 1 mm and do not have a fiber length and crimpability (crimpability) required for forming a needle felt. Cannot be felted. In addition, even if needle felt is formed together with other fibers, the entanglement with other fibers is poor, the wear resistance is poor, the fibers are easily broken, and the fibers are scattered. It can not be used for etc.

材としては使用できない。In Japanese Patent Application Laid-Open No. Sho 58-46145, a mixed yarn of a ceramic fiber and an oxidized fiber obtained by firing and firing an organic fiber such as an acrylic fiber is reinforced with a metal wire such as a brass wire. A heat insulation cloth in which the yarn is plain-woven has also been proposed. However, this cloth is excellent in bending resistance and abrasion resistance, but has poor surface smoothness, and thus may be damaged when it comes into contact with, for example, a soft molded product immediately after aluminum extrusion. Therefore, it cannot be used as the pad material.

が得られることに着目し、本願発明をなすに至った。Accordingly, the present inventor has conducted research and development on a needle felt material which can be manufactured at a lower cost than the conventional one and which can be optimally used for the above-mentioned applications. Since it has excellent heat resistance (-260 to 1170 ° C) and long fibers can be obtained, it can be entangled with other fibers necessary for producing needle felt, and has a specific gravity of 1.6. Because of this, it is excellent in lightness, and furthermore, if basalt fiber is made into needle felt, soft cushioning and surface smoothness can be obtained, so I learned that it is most suitable as a pad material for scratch protection. Although basalt fiber has high tensile strength, it is inferior in bending resistance and abrasion resistance and breaks immediately when subjected to repeated deformation and load, so basalt fiber cannot be used alone. I knew that. Based on this understanding, if the basalt fiber's weaknesses of flex resistance and abrasion resistance are supplemented with other materials, it will be possible to obtain a needle felt that can be optimally used as a pad material etc. that is inexpensive and has excellent heat resistance. Attention was paid to the present invention.

Moreover, since long fibers can be obtained by melt spinning, the entanglement with other fibers necessary for forming a needle felt is also improved. In addition to being excellent in lightness, soft cushioning and surface smoothness can be obtained by forming a needle felt. Furthermore, by mixing inorganic fibers, metal fibers, and heat-resistant organic fibers, which are lacking in bending resistance and abrasion resistance, into the basalt fiber, needles with extremely high heat resistance that have never existed before A felt is obtained. This needle felt is used as a pad material for underlaying and receiving members of products in various factories, a liner material around various engines where high heat is generated, a heat insulating material around high heat pipes, and an interior material in a room where high heat is generated Suitable use can be made as the above.

At this time, the basalt fiber is 90% by weight.
In the above case, when the needle felt is used, sufficient bending resistance and abrasion resistance cannot be obtained by other fibers. On the other hand, in the case of 30% by weight or less, sufficient heat resistance cannot be obtained. Therefore, the above mixing ratio is preferable.

As the heat-resistant organic fibers, for example, para-based, meta-based, and aromatic aramid-based aramid fibers, aromatic polyamide fibers, and polybenzazole fibers are used. Here, as the para-based aramid fiber, Kevlar manufactured by DuPont, Teijin's Technora, and polyparaphenylene benzoxazole fiber are used, and as the meta-based aramid fiber, Nomex manufactured by Dupont and Conex manufactured by Teijin are preferably used. Can be Further, as the aromatic polyamide fiber, HT-1 fiber, 6
T nylon fiber, aromatic copolyamide fiber and the like, polybenzazole fiber, polybenzoxazole,
Homopolymers such as polybenzothiazole, and fibers composed of random sequential or block copolymers composed of these components are preferably used. Further, stainless steel fibers, aluminum fibers and the like are used as the metal fibers. At this time, the stainless steel fiber
It is excellent in corrosion resistance and heat resistance, and also excellent in bending resistance and abrasion resistance, so that it can be suitably used. Particularly, by blending the stainless steel fiber with each of the above-mentioned fibers, the heat resistance and strength of the needle felt can be greatly improved.

A test for loss on ignition (%) based on L 1013-1994 was performed. The smaller the value of the ignition loss, the better the heat resistance. As a result, 2.2% at 400 ° C.
It became 14.9% at 600 ° C and 14.7% at 800 ° C. In addition, each of these values is a result at the time of heating for 3 hours. As is clear from the above test results, the needle felt is extremely excellent in heat resistance, and is effective as a pad material for each of the tables and the like. In addition, the specific gravity of the needle felt is about 1.6, so that the weight is excellent. Furthermore, the needle felt was bent and rubbed many times, and the bending resistance and the abrasion resistance were examined, but breakage and deterioration hardly occurred. Moreover, the needle felt has a soft cushioning property and a smooth surface when touched by hand. Therefore, the needle felt is most suitable as the pad material. Furthermore, although Kevlar fiber is blended in the above needle felt, since this fiber is mixed in the basalt fiber,
It was confirmed that even in a high-temperature atmosphere at 800 ° C., heat resistance was not significantly affected.
