Simultaneously, a flameproofing treatment is made on the whole wick body 1 which is cut to suitable sizes to form the heat resisting combustion part 2, and the fuel suction part 3 positioned therebelow and adjacent thereto is connected (4) thereto by sewing-up by means of a sewing machine.

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, the most popular wicks for combustion appliances have been made of a thick fabric made of cotton yarn or cotton yarn/rayon yarn blend as a fuel suction part, and a flame-resistant thick fabric made of glass fiber or glass fiber/carbon fiber placed above it as a combustion part. It has long been used as a typical core.

However, such a core has the disadvantage that a special machine must be used to produce a thick fabric, resulting in low production productivity and high cost. In other words, thick fabrics use very thick cotton threads such as 8 1o threads as warp yarns, have a special weaving structure, and are so thin that they cannot be fabricated using regular machines and are expensive. It could not be manufactured with high productivity.

As an idea to increase the productivity of wicks for combustion appliances, a woven or thin cloth mainly made of glass fiber is prepared in advance, and a smooth-surfaced felt made mainly of glass fiber wool is prepared separately, and both sides of the woven or knitted cloth are prepared in advance. Alternatively, there is an attempt to manufacture a thick wick for a combustion appliance without using a special loom by placing the felt on one side and hammering the felt with a needle machine to combine them into two bodies (Jikkosho). 45-13978).

According to the description in the public axis, the above-mentioned core for combustion appliances has felt intertwined with woven fabric or thin fabric, so even when combustion is stopped, the flow of fuel is prevented and the fuel is sufficiently stored in the woven fabric or thin fabric. It is said that there is an advantage that combustion starts quickly and there is no chance of re-ignition.

In addition, as a similar structure, instead of the smooth surface felt mainly made of glass fiber wool, a felt made by intertwining and compressing metal fibers or carbon fibers (
(See Utility Model Publication No. 850-75434) or one using felt mainly made of wool-like acrylic synthetic resin fibers which are more heat resistant than glass fibers (Japanese Utility Model Publication No. 140-732/1983). Since these wicks for combustion appliances also use woven or knitted fabrics 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 that the suction speed of liquid fuel such as kerosene used as fuel is high, so that a large amount of fuel can be combusted to generate a high calorific value. The purpose of the present invention is to provide wicks for combustion appliances.

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 combustion due to its high liquid fuel suction speed.

Still another object of the present invention is to provide a combustion appliance which has the advantage of being extremely easy to manufacture, simple to operate and can be manufactured at low cost, and therefore can be manufactured at low cost in addition to the above-mentioned advantages. The core is to provide 5- core.

Yet another object of the present invention is to have excellent dimensional stability not only during storage before being installed 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 during use and become unable to move up and down smoothly in a metal slit.

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

According to the present invention, such objects and advantages of the present invention include one or more layers of long fibers consisting of a plurality of non-heat resistant long fibers arranged substantially in one direction and a random web of non-heat resistant short fibers. The long fiber layer and the short fiber random web layer are composed of a short fiber random web layer with the short fiber random web layer forming the outermost layer. For wicks for combustion appliances, which are alternately laminated and physically integrated to prevent peeling, flame retardant (flame retardant 6-) treatment is applied to the entire wick or only the vicinity of the combustion part. This is achieved by using a wick for a combustion appliance that has a heat-resistant combustion part.

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 connected 4 to the lower part of a heat-resistant combustion part 2 by means such as sewing with a sewing machine.

The heat-resistant combustion section 2 of the present invention includes one or more layers of a long fiber layer 22 consisting of a large number of non-heat-resistant long fibers arranged substantially in one direction and a plurality of non-heat-resistant short fiber random web layers 2b. The long fibers forming long fiber Mii (2a) include, for example, EVA, rayon, cellulose acetate, polyamide, acrylic, polyester, polyvinyl formal, polyethylene, polypropylene, polyvinyl chloride, It can be a non-heat resistant fiber such as wholly aromatic polyamide. Among these, in particular polyamides such as 6-nylon, 6.
6-Nylon, polyesters such as polyethylene terephthalate, polyethylene or polypropylene are easily available industrially and are preferably used.

The long fiber layer can be composed of one type of these long fibers,
Alternatively, it can be composed of a mixture of two or more types.

These long fibers preferably have a diameter of about 0.003 to about 0.
It is used with a thickness of 0.3m. The long fibers made of thermoplastic resin are preferably drawn yarns or drawing heat-treated fibers.

Further, the short fiber web layer (2b) may be made of, for example, rayon, cellulose acetate, polyamide, acrylic, polyester, polyvinyl formal, polyethylene, polypropylene, polyvinyl chloride, wholly aromatic polyamide,
Non-heat resistant fibers such as cotton, linen or wool may be used alone or in combination.

Among these, webs made of materials with relatively high heat shrinkage resistance, such as rayon, wholly aromatic polyamide, cotton, or linen, are particularly preferably used.

The long fibers and short fiber webs as described above are produced by methods known per se.

The long fiber layer (21) is formed of a large number of long fibers as described above arranged substantially in one direction. In order to arrange a large number of long fibers substantially in one direction, for example, an untwisted tow consisting of a large number of long fibers is gradually expanded while applying mechanical vibration, or a tow of untwisted long fibers is Operations such as preparing a large number of base frames wound with multi-threads and pulling out a large number of long fibers from the base frames and arranging them may be performed.

In order to impart shape retention to the arranged long fiber layer, an adhesive such as an acrylic ester adhesive may be applied as necessary when or after the long fibers are arranged. .

A plurality of long fiber layers thus produced can be stacked to give a desired thickness, if necessary.

In the core of the present invention, the heat-resistant combustion section 2 consists of one or more layers of the long fibers 2λ and multiple layers of short fiber random webs M2b. For example, these are shown in Figure 2 (a) of the attached drawings.
, as seen in Figures 3 to 6, the long fiber layer 2m-
Starting with the simplest structure in which the waste is in the middle and the short fiber random web layer 2b is the outer layer, the short fiber random web layer 2b is formed as shown in FIGS. A plurality of long fiber layers 2a and a plurality of short fiber random webs 2 form the outermost layer.
A variety of structures can be adopted, including one in which the elements b and b are alternately stacked.

Furthermore, it is necessary that the long fiber layer and the short fiber random web layer as described above be physically integrated so that they cannot be separated.

The means of physical integration is, for example, needle punching or stitch bonding.

Next, either flame-retardant treatment is applied to the core formed in the above process, or as an example of flame-retardant treatment, the entire core body is subjected to flame-retardant treatment and cut into appropriate sizes. Heat resistant combustion part 2
The fuel suction part 3 is connected to the lower part of the fuel suction part 3 by means of sewing with a sewing machine or the like.

As shown in FIG. 3, the fuel wicking part 3 is made of rayon, cellulose acetate, polyamide, acrylic, polyester, polyvinyl 10-formal, polyethylene, polypyroprene, polyvinyl chloride, wholly aromatic polyamide, etc., which have good fuel wicking properties. It may be formed from a woven or knitted fabric of fibers such as cotton, linen, wool, etc. Furthermore, as shown in FIG. It may be used.

As another example, as shown in FIGS. 5 and 6, flameproofing treatment is applied only to the upper part of the two cores 11 in the vicinity of the combustion part to form a heat-resistant combustion part 12 and the lower part to be used as a fuel suction part 13. The material used is one that can form a seamless core body 11.

The above-mentioned flame retardant treatment agents include "I' RP C (tetrasdroxymethylphosphionium chloride) combined with cellulose fibers together with thermosetting metals such as trimethylolmelamine and urea, as well as APO () 1-
In addition to acylizonyl)phosphine oxyto)ammonium salts, sodium tungstate, and organic titanium compounds, many others can be used.

Furthermore, it goes without saying that the fuel suction section 3.13 can be subjected to a waterproofing treatment for the lipophilic return water by known means.

The shape of the wick can be flat to match the combustion appliance,
Moreover, it can be cylindrical as shown in FIGS. 3 to g7#5. In the figure, reference numeral 5 denotes a reinforcing tape that covers and adheres the connecting portion between the heat-resistant combustion section 2 and the fuel suction section 3.

The wick of the present invention can be suitably used as a wick for combustion appliances such as base tank type and cartridge tank type oil stoves and oil stoves. With base tank type combustion appliances, as the combustion time increases, the fuel level in the base tank decreases, so when using a conventional wick, the amount of fuel absorbed gradually decreases, causing the firepower to weaken or extinguishing naturally. There were times when I would do something like that. However, in the wick of the present invention, the heat-resistant combustion part (and fuel suction part) has a high branch speed, so even if the fuel liquid level decreases, fuel can be constantly supplied to the combustion part. , the above-mentioned inconveniences can be avoided.

In addition, the core feature of the present invention is that it is possible to generate a high calorific value by providing a high fuel suction speed, and it is also possible to greatly increase the height between the liquid fuel level in the tank and the combustion part. This also makes it possible to avoid the risk of the liquid fuel being heated to high temperatures.

Furthermore, the feature of the present invention is that the long fibers J-21 promote the absorption of fuel, and when extinguishing the fire, the fuel rapidly flows down, and as in the past, the fuel is stored in the heat-resistant combustion section 2 (12), thereby delaying the extinguishing time. Since the disadvantages can be overcome and the extinguishing time can be accelerated, the effect of reducing tar adhesion at the tip of the wick can also be obtained.

Furthermore, when the core body 11 is formed in one piece as shown in the embodiments of FIGS. 5 and 6, the connection process between the heat-resistant part and the fuel suction part is omitted, which contributes to further cost reduction. Dimensional accuracy can be further improved compared to connecting cores,
It also has the advantage of being able to be used for a long period of time without any change as it prevents deterioration over time.
