Description

[Detailed Description of the Invention] Technological V! > The present invention 1: relates to a heat-resistant woven fabric produced using ffZ spinning consisting of T2-spun T, stainless steel collar fiber, yoke key material, and ceramic fiber, particularly its heat resistance and towability.
It improves mechanical properties such as strength, bending abrasion resistance, etc.

<Prior art> Conventionally, as heat-resistant materials, heat-resistant key materials such as asbestos metal fibers have been processed into cloth-like products by themselves or by using spun yarns made by blending them with other fiber materials. Due to their material properties, these have been widely used in relatively low-temperature environments, for example, at temperatures of 600° C. or lower.

However, in the above-mentioned asbestos material, f
Due to reasons related to f IJ, its use has recently been greatly suppressed and is gradually decreasing.

On the other hand, as new materials to replace materials such as asbestos, carbon fiber and ceramic materials have been developed.
It has excellent corrosion resistance and 7 crystallization heat resistance of 1200℃ or higher. Since it is also I M, for example, F
It has already been put into practical use as a material for RM engine parts, etc., but for its spinning products, the dragon fiber material has bending #4.
9. It has poor abrasion resistance and is prone to breakage. Because its length is relatively short, it is difficult to process it by itself.

In addition, JP-A No. 58-46145 discloses a heat-insulating cloth using Ceraminoku 7 Eyevar, but the structure is RJ by carbonizing ceramic fibers and organic fibers such as acrylic fibers. #4 Using a raw yarn made from a blended yarn with Enka T Mei and reinforced with metal wire,
It is a plain woven cloth.

However, its use is limited to a simple shielding curtain that prevents welding sparks and molten metal from scattering, and there is no mention of its workability, M412 bendability, elasticity, etc.

In particular, the carbon-synthetic fibers used as one material for the cloth generally have poor flexibility and are prone to breakage, so they require advanced technology during processing such as spinning and weaving processes, and are difficult to obtain. Even the products produced by this method were not suitable for applications such as packing and belts that were subject to repeated hard processing, and were therefore of limited use.

<Object of the Invention> In view of such conventional problems, the present invention specifically aims to solve the problems of 60
It has both heat resistance that can withstand temperatures of 0°C or higher and sufficient bending abrasion resistance that does not cause wear or breakage due to use, even in the above applications. ? The purpose of this article is to provide fart-spun fabrics for industrial use.

<Disclosure of the Invention> In other words, the nJ4 of the present invention has a, I! FIIJ heat blend fabric woven with a blend system consisting of a blend of stainless steel collar fibers with a diameter of 2 to 50 μm, yam material, and bulk ceramic fibers.

An example of the present invention will be described below along with a manufacturing method thereof.

In Figure 1, the diameter of the fiber made of stainless steel tsuba is 2 to 50μ.
The warp 51.m is a blended yarn 4 made by blending a fiber material 2 of 1.m with a bulk ceramic fiber 3 containing, for example, round alumina, porcelain, etc. As an example, a cross section of a fabric 1 formed by layering and weft 6 is shown.

Layered weaving means that, as shown in the figure, the warp 5. This refers to a fabric in which one or both of the weft yarns 6 are overlapped twice or more to form a single fabric as a whole, but the fabric of the present invention may also include plain weave, twill weave, etc. by using IM on Qi. It also includes those that have been rl.

Particularly in applications where high strength and elasticity are required, such as the above-mentioned conveyor belts and packing, such thickly layered fabrics are used.

Features of the present invention] 1! One of the items is that the yarn constituting the fabric is a stainless steel textile material 2 with a fiber diameter of 2 to 50 μm.
In addition, a blended yarn 4 obtained by blending with bulk fiber 3, which is relatively short among ceramic fibers and is in an unprocessed, collected state, is used.

The RIIL spinning yarn 4 is one in which the above-mentioned fibers 23 are mixed at a ratio of, for example, 5 to 95 wt% depending on the running purpose, and twisted at a rate of about 2 to 10 times/in, and spun 31 times, Alternatively, the h-spun yarn 4 may be constructed by further twisting and twisting a plurality of the fibers.

In addition, in the thread cross section of the stainless steel fiber 2,
It does not matter if they are arranged to be appropriately dispersed or concentrated,
For example, for applications that require use in higher temperature environments, n
If the stainless steel W4 fibers 2 are uniformly dispersed or concentrated in the center and surrounded by ceramic fibers 3, direct heat influence on the stainless steel fibers 2 can be prevented. , its deterioration can be further prevented.

Furthermore, the composition of the latter twisted and twisted blended yarn may be a combination of single yarns having the same configuration, or may be a combination of different types with different thicknesses, blending ratios, etc., and can be carried out by known methods.

FIG. 2 shows, as an example of such a blended yarn, yarns that are uniformly distributed in the cross-sectional direction and twisted together.

The stainless steel fiber key material 2 used in the present invention is made of stainless steel bundled fibers with a fiber diameter of 2 to 50 μm obtained by a method such as the composite bundled elongation method disclosed in Japanese Patent Publication No. 56-11523. The so-called tow (or tow) is further cut into a desired length, for example, 20 to 10 mm, using a parlock cutting machine or the like.
It is also possible to use a sliver-like material cut to about 0+n, and a sliver-like material is particularly desirable for uniform dispersion. In addition, although stainless steel fiber materials are slightly inferior in corrosion resistance and heat resistance compared to ceramic materials, they have excellent bending abrasion resistance and towability that are similar to fir, etc., and their elasticity also lasts. The UJ ability can be greatly improved along with the tensile strength by changing the cold wire drawing processing rate. Therefore, if these are used, workability in the spinning process and the subsequent milling process can be improved, and problems such as breakage can be solved.

This tendency is especially true for materials with a tensile strength of 100 Kgf/mm2 or more.

Furthermore, in the present invention, the diameter of the m group is 2 to 501t.
m, but this is 50 μm with two Koshimaru: It becomes difficult to uniformly disperse as shown in Figure 1, and the entanglement with the ceramic fiber 3 becomes difficult, and conversely, if it is less than 2 μm, the thread itself It is difficult to achieve the objective because the elasticity is poor and stainless steel fibers are also easily affected by heat.

Next, to explain the other material, ceramic fiber, the fiber 3 is made by adding an appropriate amount of fusix to a mixture of, for example, calcined kaolin, alumina, and phosphoric acid raw material, and heating it in a 4-induction heating furnace for 2200 min.
There is a blowing method in which the material is melted by heating to about 2,300 degrees Celsius, flowed out, and blown away with compressed air or high-pressure steam, or it is dropped onto the side of a rotating disk and its centrifugal force causes m x 1
The fibers 3 are in bulk form collected by a method such as the Subinyreg method, and have a heat resistance temperature of 1200°C or more, and have a predetermined length of 1 to 5 μm for each fiber, for example. 50 mrn or less). Of course, the above values are not limited thereto).

The thus obtained T-stereles r'A fiber particles 2 and ceramic fibers 3 can be used for five purposes depending on the purpose of use.
The two are blended while opening the cotton using a fiber opening Isogane at an arbitrary blending ratio of ~95W (%), and then spun into a matched sliver using a special Ryu 1'3 machine.Then, the fibers are further spun into a matched sliver using a Rereg spinning machine, e.g. Add a twist of about 10 turns/In to complicate the entanglement between the two, and obtain a single blended yarn by applying the circumferential pressure of the twist.

In addition, after this, the method of combining and twisting several yarns to obtain a single blended yarn can be easily changed by twisting in the opposite direction (for example, 2 to 10 times/inch), and in particular, as mentioned above, The stainless steel fiber material 2 produced by this method has a rough surface due to sharp ridges 7 and grooves 8 generated in the longitudinal direction as shown in Fig. 3, and its cross-sectional shape is irregular. , the calamari with other fibers is large and strong) to create a blended yarn.

Further, the stainless steel fibers 2 may be arranged such that a sliver is arranged around the central part of the round bar, and a sliver is arranged around the round part to match the ceramic fibers.

The fiber-reinforced yarn 1 of the present invention is manufactured using the blended yarn 4 configured as described above, and therefore, even if it is a bulk ceramic fiber with a short length, it can be made of stainless steel fiber. The ceramic fibers 3 can be held securely between the fibers 2 and 3, and have excellent strength due to the circumferential pressure caused by the twisting, the scattering of the ceramic fibers 3 is small, and the elasticity, bending, and abrasion resistance of the fibers can be improved.

Furthermore, regarding the #4 heat property, by combining the two and applying twisting, it has a combined effect such that heat absorption to the stainless steel fiber 2 can be softened and direct influence can be prevented. Products require heat resistance, strength, flexibility, etc. Heat resistant conveyor belt materials Panogin materials Brake lining materials Or (j
It can be used in a wide range of applications, including as a noise-absorbing material for rollers used to transport materials in steel plants.

In addition, during manufacturing, reinforcing metal and metal cotton are compounded, or for heat-resistant applications, aramid cotton is blended together to further improve the abrasion resistance. Applications such as using r=KM l/i yarn can be made freely.

Next, the present invention will be explained in detail.

<Example-1> [SUS 316L stainless steel tsuba fibers with a set diameter of xzμm were cut into a parlock cutting machine to have an average length of 501111 mm.
Remove the sliver and remove the second one.

This stainless steel fiber was uniformly dispersed with an aluminica-based pulp-like material having an average ta 8i T ￥3 μm as a ceramis fiber at a weight ratio of 3:2. A blended yarn with a thickness of 2ffl11 was used as the lining machine, and a 3NJ overlapping cloth product with a thickness of 6+IIm and a width of 30mm was made, and its characteristics were investigated. Changes in strength due to
The ignition loss test and moxibustion prescribed by JI3 3450 were also conducted, and the repeated bending test shown in FIG. 4 was conducted to determine the number of times until breakage occurred.

The results are shown in Table 1.

This was carried out using a blended spinning system (thickness 2c++m) in which four of the fibers were mixed at a weight ratio of 3.2 and four fibers were twisted together (thickness 2c++m). A loss product was prepared in the same manner as in Example 1 and the above-mentioned tests were conducted.

Table 1 <Effects of the Invention> As detailed above, the present invention is applicable to ceramic fibers with excellent heat resistance, bulk fibers in a collected state that have not been subjected to secondary use, and stainless steel fibers. 1
2 It is made of a blend with It, and has heat resistance and strength,
This dramatically improves bending abrasion resistance and expands its range of applications.

In particular, in the present invention, for example, although #4 thermal properties are superior to conventional ones, it is possible to improve strength, elasticity, towability, and The heat resistance, which was somewhat lacking in stainless steel, has been made possible by using a blended yarn made of t!A41, a stainless steel with excellent properties. By taking advantage of the advantages of both fiber materials, such as being able to prevent deterioration, high workability can be obtained by combining the two fiber materials, and as a result, it has become possible to greatly expand the range of use.

In addition, the present invention uses ceramic fibers that do not cause any pollution problems.1. ), these are stenciled and held securely by twisting with the H1 string to prevent them from scattering. , M! As can be understood from the example, shrinkage and strength reduction due to heating temperature are very small (t), and it does not turn into carbonized dust, so 1rfh is preferable from the viewpoint of shape change during use and trench boundary surface. It is.
