Abstract

PURPOSE:To reduce a manufacturing cost, by a method wherein line layers, having non-heat resisting lines abutted on heat resisting lines for connection, and tow random layers are alternately laminated, and they are formed physically integrally in a manner that the outermost layer forms the web layer. CONSTITUTION:The wick of a combustion device consists of a wick body 1, a heat resisting combustion part 2 and a fuel suction part 3. The heat resisting combustion part 2 is constituted such that plural line layers 1a, having heat resisting lines layers 2a abutted on non-heat resisting line layers 3a for junction, and plural tow random web layers 1b are alternately laminated, and the outermost layer forms the web layer 1b. In order to prevent exfoliation of the two different layers, they are formed physically integrally by use of a needle punch, and the line layers 1a are aligned in a seamless manner over the entire length of the wick body 1. This allows promotion of a fuel suction and shortening of a fire-extinguishing time.

Description

[Detailed Description of the Invention] The present invention relates to a wick for combustion appliances such as oil stoves and oil stoves that use kerosene as fuel, and its purpose is to have good suction efficiency and excellent dimensional accuracy. The aim is to mass produce products at low cost.

Conventionally, a wick for a combustion appliance is made of a thick fabric made of cotton yarn or a cotton yarn/rayon yarn blend as a fuel suction part, and a heat-resistant thick fabric made of glass fiber or glass fiber/carbon fiber is placed on top of it as a combustion part and wrinkled. It has been used for a long time as the most typical wick.

However, such a core has the disadvantage that a special machine must be used to produce a thick fabric, resulting in low productivity and high cost. In other words, a thick fabric is one in which the warp is made of extremely thick cotton yarn such as 1oli: 8 flat threads, and the weaving structure is also special.
Therefore, it was not possible to use ordinary machinery and it was not possible to manufacture with high productivity.

As a way to increase the productivity of wicks for combustion appliances, glass &
Preparing in advance a woven or knitted fabric mainly made of glass fiber wool, and separately preparing a surface-smooth felt made mainly of glass fiber wool, disposing the felt on both or one side of the woven or knitted fabric, Hit these with a needle machine'C
Attempts have been made to manufacture thick wicks for combustion appliances by a method of integrally joining the wicks without using a special loom (see Japanese Utility Model Publication No. 13978/1983).

According to the publication, the above-mentioned wick for combustion appliances has felt intertwined with woven or knitted fabric, so even when combustion is stopped, the flow of fuel is prevented and the fuel is sufficiently stored in the woven or thin fabric. Therefore, it has the advantage of quickly starting combustion when reignited.

In addition, as a similar structure, instead of the surface-smooth felt mainly made of glass fiber wool, a felt made by intertwining and compressing metal fibers or carbon fibers (
(Refer to Japanese Utility Model Application Publication No. 75434/1983) or one using felt mainly made of wool-like acrylic synthetic resin fibers, which are more heat resistant than glass fibers (Refer to Japanese Utility Model Application Publication No. 1987-75434).
140732) is known. Since these wicks for combustion appliances also use textiles or fine cloths mainly made of glass fibers, it is clear that they are wicks with improved oil storage properties, like the previous wicks.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a wick for a combustion appliance with a novel construction.

Another object of the present invention is to provide a lamp used as a fuel, which has a high suction speed for liquid fuel such as oil, and therefore can burn a large amount of fuel to generate a high calorific value. The purpose is to provide sanitary pads.

Still another object of the present invention is that the suction speed of the liquid fuel is high, so that the distance from the liquid level of the liquid fuel to the combustion part is high.
To provide a wick for a combustion appliance, which can take a large amount of heat, prevent liquid fuel from being heated to a high temperature, and continue safe combustion.

Still another object of the present invention is to provide a wick for a combustion appliance that can smoothly ignite (re-ignite) or continue burning due to its high liquid fuel wicking rate.

Still another object of the present invention is to provide a combustion appliance which has the advantage of being extremely easy to manufacture and can be manufactured at low cost with simple operations, and therefore can be manufactured at low cost in addition to the above-mentioned excellent advantages. The purpose is to provide sanitary pads.

Still another object of the present invention is to have excellent dimensional stability not only during storage before installation in a combustion appliance but also during use while installed in a combustion appliance; To provide a wick for a combustion appliance that does not gradually shrink while being installed and used and cannot move up and down smoothly in a metal slit.

Still another object of the present invention is to form an integral core with no connecting part between the heat-resistant combustion part and the fuel suction part, eliminate various disadvantages caused by the C connection, and further increase the suction speed of liquid fuel. The purpose of the present invention is to provide a wick for a combustion appliance that can be mass-produced at low cost by shortening the process.

Further objects and advantages of the present invention will become apparent from the description below.

According to the present invention, the objects and advantages of the present invention are to form a layer of long fibers J- in which a large number of heat-resistant long fibers and non-heat-resistant long fibers that are arranged substantially in one direction are butted and connected. or a plurality of short fiber random web layers, and the long fiber layers and short fiber random web layers are alternately laminated so that the short fiber random web J- forms the outermost layer, and the short fiber random web layer is laminated alternately so that the short fiber random web J- forms the outermost layer. This is achieved by physically integrating the combustion appliance wick to prevent

Embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a core body formed in a cylindrical shape, and a fuel suction part 3 is integrally provided at the lower part of a heat-resistant combustion part 2.

The core 1 of the present invention includes a large number of heat-resistant long fibers J11i2λ substantially arranged in one direction, and a non-heat-resistant long fiber layer 3λ.
It consists of one or more layers of heat-resistant (or non-heat-resistant) short fiber random webs 1b connected by butts, and the long fibers forming the heat-resistant long fiber layer 2@. For example, carbon fibers, glass fibers, ceramic fibers, asbestos fibers may be used alone or as a mixture of untwisted or moderately twisted fibers of appropriate thickness.
Further, the long fibers forming the non-heat resistant long fiber layer 3a include, for example, rayon, cellulose acetate, polyamide, acrylic, polyester, polyvinyl formal, polyethylene, polypropylene, polyvinyl chloride, wholly aromatic polyamide, cotton, hemp, wool, etc. Non-heat resistant fibers can be used alone or in combination.

In addition, when short fiber random web @1b is heat-resistant, heat-resistant fibers such as carbon fiber, glass fiber, ceramic fiber, asbestos fiber, etc. are used alone or in combination, and when it is non-heat-resistant, heat-resistant fibers such as carbon fiber, glass fiber, ceramic fiber, asbestos fiber, etc. For example, fibers such as rayon, cellulose acetate, polyamide, acrylic, polyester, polyvinyl formal, polyethylene, polypyroprene, polyvinyl chloride, wholly aromatic polyamide, cotton, hemp, wool, etc. are used alone or in combination.

The long fiber layer and the short fiber web as described above are produced by methods known per se.

In order to arrange a large number of long fibers substantially in one direction, for example, a tow consisting of a large number of long fibers that is untwisted or moderately twisted is gradually expanded while applying mechanical vibration, or Alternatively, operations such as preparing a large number of base frames in which untwisted or moderately twisted long fiber multi yarns are wound up, and pulling out a large number of long fibers from the base frames and arranging them.

In order to impart shape retention to the arranged long fiber layer, an appropriate amount of adhesive may be applied when or after the long fibers are arranged, if necessary. (The manufactured long fiber layers 2a and 3a can be stacked in multiple layers to give a desired thickness as necessary, and both long edges @1fi
2a and 3a are butted together to form a desired long fiber layer 1a.

These include, for example, the simplest structure as shown in Figure 2 of the attached drawings, which has one layer of long fibers as the middle layer and the second layer of short fiber random web @1b as the outer layer, and as shown in Figure 3. It is possible to adopt a Kaede structure up to a structure in which a plurality of long fiber layers 1a and a plurality of short fiber random webs 1b are alternately stacked so that the short fiber random web bib forms the outermost layer. can.

Furthermore, the long fiber layer and the short fiber random web shield as described above must be physically integrated so that they cannot be separated. The means of physical integration is, for example, needle punching or stitch bonding.

10- The shape of the wick can be flat to match the combustion appliance,
It can also be cylindrical as shown in FIG.

Next, in the case where the short fiber random web layer 1b uses non-heat resistant fibers, flame retardant treatment is applied to the whole or only the vicinity of the combustion part. As agents, TBPC (tetrastroxymethylphosphonium chloride), trimethylolmelamine,
Cellulose fibers are combined with thermosetting metals such as urea to form outer APO ()! In addition to Js(1-acylizonyl)phosphineoxyto)ammonium salts, sodium tungstate, and organic titanium compounds, many others can be used.

The wick of the present invention can be suitably used as a wick for combustion appliances such as base tank type and cartridge type oil stoves and oil stoves. With base-type combustion equipment, as the combustion time increases, the fuel level in the base tank decreases, so when using a conventional wick, the suction of fuel gradually decreases, the firepower weakens, or the fire extinguishes naturally. There were times when I did something like that. However, since the core of the present invention has extremely high wicking speed since the heat-resistant long fibers 2a and the non-heat-resistant long fibers 3a are integrally connected to form the long fibers Mla, Even if the liquid level drops, fuel can be constantly supplied to the combustion section, so the above-mentioned disadvantages can be avoided.The core of the present invention is also characterized by a high fuel suction speed, which generates a high amount of heat. It also makes it possible to increase the height between the liquid level of the liquid fuel in the tank and the combustion part, thereby avoiding the risk of the liquid fuel being heated to high temperatures. be.

Furthermore, the feature of the wick of the present invention is that the long fiber layer 1a promotes the uptake of fuel, and when the fire is extinguished, the fuel flows down rapidly, and unlike the conventional example, the fuel is stored in the heat-resistant combustion part 2, which delays the extinguishing time. Since this can speed up the extinguishing time, the effect of reducing tar adhesion at the tip of the wick can also be obtained.

Furthermore, the feature of the core of the present invention is that unlike the conventional vertical core in which the heat-resistant combustion part 2 and the fuel suction part 3 are formed separately and contacted by a suture means, the heat-resistant combustion part 2 and the fuel suction part 3 are different from each other. Since it is made of a seamless one-piece core, it has various drawbacks that conventional cores have, such as reduced wicking due to separation of the seams, uneven combustion, unevenness in the top and bottom of the core, inability to extinguish, poor dimensions, and increased cost. It is possible to eliminate all of these.
