維製高密度フエルトの製造方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a carbon fiber high-density felt suitable as a heat insulating material, a cushioning material, a secondary battery electrode material, etc. during high temperature heat treatment.

断熱材等として使用されている。2. Description of the Related Art A carbon fiber felt is excellent in heat resistance and heat insulation at high temperatures.
It is used as a heat insulating material in high temperature furnaces such as vacuum deposition furnaces and semiconductor single crystal growth furnaces.

密度化を目指した炭素繊維製フエルトが開発されてい
る。This kind of carbon fiber felt is required to have heat insulating properties, mechanical strength, and durability in order to raise and lower the temperature in a short time, reduce power consumption, and downsize equipment. Since these three requirements are achieved by increasing the density of the felt, carbon fiber felts have been developed aiming at high density by various means.

より得たものである（特開平２−４６８９１号公報）。First, in the first felt, a batt layer made of flame-proofed or carbonized fibers is placed on the upper surface of a base fabric made of a woven or non-woven polymer fiber which is carbonized or graphitized by firing. The base cloth and the batt layer are integrated by needle punching from the side of the batt layer, and are obtained by firing this (JP-A-2-46891).

る（特開平１−２７２８５４号公報）。In the second felt, a carbon cloth base cloth made of carbon fiber is brought into contact with one or both sides of the carbon fiber batt layer, and a part of the fiber of the batt layer is made by needle punching. The bat layer and the base fabric are integrated by entanglement of the fibers, and the integrated product is impregnated with a resin in order to prevent deformation and powdering (Japanese Patent Laid-Open No. 1-272854).

３−１４６６５号公報）。Further, the third felt is a mixture of carbon fiber and polymer fiber which is carbonized or graphitized by firing,
It is obtained by mechanically compressing and entwining the fibers and the polymer fibers, and then firing the fibers (JP-A-3-14665).
【０００７】[0007]
【発明が解決しようとする課題】しかしながらこれら従
来のフエルトは種々の欠点を有し、到底満足のいくもの
ではなかった。即ち、第１のフエルトは焼成後の平均嵩
密度がせいぜい０．０５ｇ／cm3 にしかならず、断熱
性，機械的強度，及び耐久性の点で劣るものであった。However, these conventional felts have various drawbacks and are not completely satisfactory. That is, the first felt had an average bulk density of at most 0.05 g / cm 3 after firing, and was inferior in terms of heat insulating property, mechanical strength, and durability.

め樹脂の含浸工程が必要となって作業工程が多くなると
共に、粘着性を有する樹脂を使用するので作業性が低下
するという課題をも有していた。In the second felt, the batt layer and the base cloth are made of carbon fiber, and it is not only expensive to weave the yarn of carbon fiber, but the elongation of the carbon fiber is remarkably small and needle punching is performed. In this case, the fiber is frequently broken, and the product is easily deformed or pulverized, so a resin impregnation process is required to prevent this, and the number of work processes is increased. There was also a problem that the property deteriorates.

1/2 量前後を占める非炭素繊維の方の炭化に伴う重量減
少による密度低下は否めないと思われる。Further, the effect of tightening by needle punching is generally remarkably improved by entanglement with a woven fabric having a high fiber density, but the third felt uses a blended bat without using a woven fabric or the like. It is difficult to tighten because it is a thing, and it is inevitable to increase the number of times of needle punching to obtain a desired tightening. For this reason, the carbon fiber in the mixed spinning bat is cut, and the strength as a felt becomes small, and it is considered that the manufacturing itself is difficult especially for a thin material (2 to 3 mm). The high number of needle punching means that the work time is long. It should be noted that the whole vat should be mixed uniformly and
It is undeniable that the density of non-carbon fibers, which occupy about 1/2 amount, decreases due to weight loss due to carbonization.

明には不適である。The cloth body 2 is made of a tubular material which is opened in the direction of needle punching, and the material thereof may be a general cloth material, but in this embodiment, vinylon gauze cloth, which is hardened by pasting, is used. I was there. In addition, the fabric body 2 has a material composition of both warp and weft yarns (density): 5 to 15 yarns / c
m, yarn count: 80 to 25 m, and fabric weight: 60 to 160 g / m 2 are selected, but in this embodiment, the number of yarns inserted is 10 / cm, yarn count 16
A vinylon gauze cloth having a metric count and a fabric weight of 90 g / m 2 was used. The material conditions are selected with reference to the fact that the cloth body 2 moves integrally with the bat layer 1 during needle punching and that the cloth body 2 is easily separated from the bat layer 1 after needle punching. For this reason, the monofilament woven fabric is slippery with the batt layer 1 and is difficult to move integrally, so that the woven fabric as it is, that is, the one which is not subjected to the post-treatment is not suitable for the present invention. Further, a too soft cloth is not suitable for the present invention because it is liable to sink into the batt layer at the time of needle punching and peeling after needle punching becomes difficult.

After needle punching, the cloth body 2 was peeled from the batt layer 1 to obtain batt layers A and B shown in Table 1. At this time, the bat layer A was obtained by needle punching the bat layer 1 together with the fabric body 2 with the upper and lower surfaces turned up.

The needle punching conditions at this time are as follows, and the configuration of the batt layer C is as shown in Table 2.
