Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a common wick for combustion stoves, kerosene stoves, etc. that use kerosene as fuel, and its purpose is to provide a non-woven interlining with excellent fuel wicking efficiency. The aim is to mass produce it at low cost.

Conventional combustor common cores of this type have a heat-resistant combustion section made of a thick fabric made of glass fiber or a blend of carbon fiber and carbon fiber #1 connected to the upper part of a fuel suction part made of cotton yarn or a thick fabric made of a blend of cotton and rayon. The interlining is formed into a flat or cylindrical core.

The combustor common interlining having such a structure has various drawbacks similar to humans.

1. Productivity is extremely low and inefficient because production relies on old-fashioned special looms.

2. Particularly in the fuel suction section, the warp is made of very thick cotton yarn, such as 8-strand 10 yarn, and is woven with a narrow and special structure, which limits the number of textile machines, and furthermore, the area used is limited. Due to its large size, there is often a shortage of supply.

3.Dimensions tend to vary due to changes over time, and the defective tip is high, and the core guide tube of the instrument contracts during use, which tends to cause problems due to poor lifting of the core.

4. Holes are likely to occur during cutting, requiring treatment to prevent holes such as oversewing or adhesive application. 5. The intermingling of the warp and weft yarns impairs the efficiency of fuel absorption.

6. Due to fiber formation, the surface is uneven, and gaps are created between the warp and weft threads of the warp and weft, resulting in poor adhesion to the core guide tube of the device, creating an unnecessary draft effect between the inside of the tank and the outside air, which can lead to combustion. performance and C/fire extinguishing performance.

7. The reinforcing tape attached to the connection between the fuel suction part and the heat-resistant combustion part is difficult to adhere to.

8. Various markings (manufacturer name, model number, dimensions, etc.) are difficult to see.

As an attempt to improve the productivity of the cloth tray used as a fuel suction part, weft insertion warps (rassel aita) have been proposed, but the thickness of the cloth is not sufficient, so it is difficult to overlap several sheets. Unless such measures are taken, the fuel necessary to sustain combustion will not be drawn up.In addition, when the device is attached to the device, a vertical gap will be created, resulting in an unnecessary draft effect as mentioned above. This had the disadvantage of poor combustion performance and fire extinguishing performance.

The present invention has been made to eliminate the above-mentioned drawbacks, and embodiments thereof will be described below with reference to the drawings. A is a fuel absorbing interlining, which is composed of a short fiber web layer 1b made of natural fibers or chemical fibers, or on both sides thereof, a short fiber web layer 1b containing a short fiber random web of natural fibers or chemical fibers alone or mixed in an appropriate proportion. The random web of short fibers is intertwined with the long fibers using a two-dolpa punch, and integrated into a flat plate having a desired thickness. (See Figures 1 and 2) In the case of the long fiber layer 1a and the short fiber random web layer,
The thicknesses of the long fiber layer 1a and the short fiber random web layer 1b may be appropriately adjusted within the desired thickness range, and the layers may be polymerized.

The material of each fiber should be selected after carefully examining the fuel absorption properties. Examples include long fibers, carbon, ceramics, asbestos fibers, etc., heat-resistant fibers, or natural fibers such as cotton, hemp, rayon, polyester, etc. The chemical fibers are used alone or mixed together in a suitable manner and arranged in parallel to form a long fiber layer 1a having a constant thickness. As a method of aligning a large number of long fibers, for example, polyester, nylon, etc. v
In addition to gradually expanding the tow while applying fim-like vibrations, or pulling out a large number of p@twisted long fiber multi yarns from a creel stand and arranging them in parallel, you can also use appropriately twisted natural fiber yarns. There is a method of aligning the fibers in parallel.If necessary, adhesive may be applied to the long fibers that are aligned in parallel to increase the stability of the shape for convenience in subsequent processes, or several layers may be stacked. This provides sufficient thickness for fuel wicking. The silky long fiber layer 1a obtained in this way has the same effect as if many capillaries were passed in the length direction, making it easier to absorb fuel, but since there are fewer intersections between the fibers, it is easier to absorb the fuel. There is a problem with tearing.

The present invention provides a short fiber web in which natural fibers or chemical fibers are mixed alone or in appropriate amounts in the long fiber layer 1a.
By polymerizing b and integrating with needle punch,
Because the short fiber random web is entwined with the long fibers, the tearing problem mentioned above is solved, and the product has a uniform thickness and smooth surface compared to conventional products, making it possible to coat the product with no holes. be.

According to the present invention, if the fuel suction ability is insufficient, the amount of fibers with good suction characteristics (such as cotton, linen, rayon, etc.) may be increased, or the fibers may be subjected to a shrinking process using a calendar or the like. It is also possible to promote the capillary effect by narrowing the fiber spacing. The above-mentioned interlining is used by punching (or cutting) the long fibers so that they are oriented substantially vertically or diagonally, and connecting them to a flat or cylindrical core.

According to the present invention, the various effects described above can be obtained.

1. Since it is possible to produce a wide width and high-speed core in the city, it is possible to obtain a core with higher productivity and lower cost than the conventional method.

2. Since it is a non-woven fabric band, there will be no holes in the cutting edges.
It can be cut by punching, etc., and can be manufactured uniformly without any variation in process.

3. Dimensional variations due to changes over time do not occur, and troubles caused by dimensional changes during use can be eliminated.

4,! The wicking of fuel can be promoted by capillary action caused by the fiber layer.

5. By mixing the materials of the fibers, it is possible to adjust the amount of fuel sucked up, and the shortcomings of each #l fiber can be compensated for.

6. Because the surface is less uneven, the adhesion of the reinforcing tape is better, preventing it from peeling off during use, and making it possible to clearly stamp various markings (manufacturer name, model number, dimensions, etc.), and it also adheres well to the surface of the container. The gaps between the fibers and between the fibers and the appliance are reduced, improving combustion performance and fire extinguishing performance.

7. It is possible to make cuts such as horizontal splits and bending parts without causing holes.

8. The weight of the interlining is lighter than conventional products.

9. When formed into a cylindrical core, wrinkles, folds, etc. due to the difference in development length between the inner and outer surfaces do not occur due to the expansion and contraction of the short fibers, unlike in the conventional case.

10. Since the short fibers are randomly intertwined, the claws of the core holding part can be properly locked without damaging the fibers, so reinforcing tape can be omitted.

Note that FIG. 3 shows the configuration of FIG. 1 i and FIG. The heat-resistant combustion wicks 4 made of aluminum or IM are butted together and sewn together 5 to form a cylindrical shape and sewn! ! 55
4 shows an example in which a reinforcing tape 6 is attached to the wick, and 7 in the figure is a cut for dividing the hem. In FIG. Common knowledge 11a and short fiber ML random web layer 2b may be produced by cutting heat-resistant combustion interlining B made from heat-resistant fibers such as tlff lath, carbon, ceramics, and asbestos fibers.

It goes without saying that the fuel wicking interlining A and the heat-resistant combustion interlining [5] can also be multi-layered as shown in Figure 2, Figure 2. It can also be formed by polymerizing the fiber layer 1a or the short a41 layer 1(''.

After making the hem splitting cut 7 shown in Figure 3 above, N! In addition to the i-spread type, as shown in Figure 4, a number of bending cuts 8 and 8 are drilled in the lower part, leaving the lower end, to create a 7-type fuel suction system (also known as a lantern type). A core 3 can also be formed. As shown in FIG. 51, if the bending/stretching cuts 8a are arranged diagonally in the twisting direction of an instrument that is to be twisted and raised while lowering the core L, the core can be moved smoothly without resistance.

Furthermore, as shown in FIG. 11, according to the present invention, 4 is also woven at the bottom of the heat-resistant combustion wick 4a. The completed fuel wick 14
It is also possible to connect 5a.

In addition, as shown in FIGS. 7 and 8, the long fiber layer 9 is formed of heat-resistant fibers, and a part of the fuel absorption layer 9 (short fiber random web layer 9a of 1 is used as a fuel absorption layer) is added to the long fiber layer 9. It is also possible to produce a seamless integral interlining C by polymerizing short fibers of heat-resistant fibers and short fibers of the heat-resistant combustion part C2/dumb web layer 9b, respectively. As an example, as shown in Figures 9 and 10, common knowledge of heat-resistant fibers 1
A long fiber layer 1 formed by butting i10a and long fibers 10b having good fuel absorption properties or connecting them by appropriate means.
0, short fiber random webs of natural fibers or chemical fibers can be polymerized and arranged to produce a seamless integral interlining. It is unnecessary.

In addition, as shown in No. 4V, the joint between the fuel wick 3 and the heat-resistant combustion wick 4 and the cylindrical joint are each formed into a serrated joint 12.1.
3, connect them so that they interlock with each other, and sew them with single or double row straight stitches 12a and 13a. This will improve the adhesion of the joints and prevent fuel suction failure due to separation between the two, as in the past. 1ILII which prevents defects and is simple without the complicated nogzagumishi/conventional methods.
Being able to sew with an A-stitch sewing machine will improve efficiency.

Furthermore, as an alternative example, the part of the combustible fiber near the combustion part is treated with flame retardant treatment to give it heat resistance, and the entire fuel wick or the part immersed in the fuel is treated with sweat water. It is also possible to apply Flame retardant processing is a processing method that makes combustible organic fibers flame retardant, such as TRPC (
Tetrastroxy, methyl 7-osphonium chloride) is reacted and bonded to cellulose fibers together with a thermosetting compound such as trimethylolmelamine or urea.

The above-mentioned Haka APO+)'Jsu(]-7 is used as a flame retardant agent.
There are many types, such as those using noridenyyl)phosphine oxyto)ammonium hydrochloride, sodium tungstate, organic titanium compounds, and others. Furthermore, condensation processing is a process in which a thin hydrophobic film is applied to prevent water from penetrating fibers, paper, etc., and the process is made waterproof by washing with water. , zirconium salts, silicone resins, metal soaps, waxes, 77-element compounds, and many others.

- Note: It goes without saying that neither flameproofing nor dehydration processing inhibits lipophilicity.

The purpose is to mass-produce heat-resistant combustion parts made of imported cloth with excellent suction efficiency at a low cost. Conventionally, a thick woven fabric made of cotton yarn or single line/rayon yarn mixed yarn is used as the fuel suction part, and a flame-resistant thick woven fabric made of glass fiber or glass fiber ring/precious fiber is placed on top of the fuel wicking part as the combustion part. The most typical type of wick has long been used for combustion appliances. Therefore, it had the disadvantage of low raw koji quality and high cost.In other words, thick *
For example, @ is a warp made of 1011 hand threaded 8-strand cotton yarn of maximum count, and the weaving structure is also special and narrow, making it impossible to use normal machines and requiring high production. It could not be structured by gender. As an idea to increase the productivity of wicks for combustion appliances, a woven cloth or cloth mainly made of glass fibers is prepared in advance, and a felt with a smooth surface mainly made of glass fibers and wool is separately prepared, Special Ii/I4
There is a known attempt to manufacture a thick wick for a combustor without using #I4 (see Japanese Utility Model Publication No. 13978/1983). According to the publication, the above-mentioned wick for combustion appliances has felt intertwined with textiles or thin cloth, so even when combustion is stopped, the flow of fuel is blocked and the fuel is sufficiently stored in the textiles or inside the city. Therefore, it has the advantage of quickly starting combustion at the time of re-ignition. In addition, as a similar structure, instead of the smooth-surfaced felt mainly made of fine glass wool, a felt made of fine metal or carbon fiber entangled and pressed (
Actual M @ No. 50-75434) or one using felt mainly made of wool-like acrylic synthetic resin fibers that are more heat resistant than glass fibers (actual M introduction 49-
No. 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 wick for a combustion appliance, which has a large suction capacity for liquid fuel such as kerosene used as fuel, and therefore can burn a large amount of fuel and generate a high calorific value. It is about providing. Still another object of the present invention is that the suction capacity of the liquid fuel is large, so that the height of the combustion chamber is 11 from the liquid level of the liquid fuel.
1) can be taken in a large pot, thus preventing the liquid fuel from being heated to bird temperature, making safe combustion a! An object of the present invention is to provide a wick for a combustion appliance that can be controlled. 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 wicking capacity for liquid fuel. Still another object of the present invention is to provide a combustion appliance which has the advantage of being extremely easy to manufacture in terms of structure, simple operation, and low cost, 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 when stored before being attached to a combustion appliance, but also when used while being attached to an Immediate baking appliance, and therefore, for example, when used while being attached to a combustion appliance. To provide a wick for a combustion appliance which does not gradually shrink during heating and become unable to move up and down in a circle #l in a slit made of gold W4. 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 long fiber layers consisting of a plurality of heat resistant long fibers arranged substantially in one direction and a heat resistant short fiber random web layer. The long fiber layer and the short fiber random web layer are alternately arranged so that the short fiber random web layer forms the outermost layer, and are physically integrated so that they cannot be separated. This is achieved by a combustor A) I core consisting of a heat-resistant combustion section and a fuel suction section connected adjacent to the heat-resistant m-twill section. Embodiments of the present invention will be described with reference to the drawings. 1 is a core carved into a cylindrical shape, and a fuel suction 1s3 is placed below the heat-resistant combustion part 2.
are integrally connected 4 by means such as sewing machine stitching. The heat-resistant combustion section 2 of the present invention is composed of one or more layers of long fibers 112m consisting of a large number of long fibers arranged substantially in one direction and multiple layers of short fiber random webs J12b. The large number of long fibers that make up 1m2m of fibers are made of heat-resistant fibers such as carbon fibers, glass fibers, ceramic fibers, asbestos fibers, etc. alone or in combination, untwisted or moderately twisted, and of an appropriate thickness. The short fiber random web 111 may be made of heat-resistant fibers such as carbon fibers, glass fibers, ceramic fibers, asbestos fibers, etc. alone or in combination. The random woven fibers are produced in a manner known per se. To arrange a large number of long edges substantially in one direction, for example, a tow made of a large number of long fibers, untwisted or moderately twisted, is gradually expanded while applying mechanical vibration, for example. 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 there and arranging them. In order to impart shape retention to the arranged long fiber layer, an appropriate adhesive may be applied, if necessary, when or after the long fibers are arranged. The long edge IMJllim2m thus constructed can be bent multiple times to provide the desired thickness as required. In the core of the present invention, the above-mentioned long fiber JII
21 and multiple layers of short fiber random web m2b. These include, for example, long fiber m2a-noodles, as shown in the attached drawings J11, Figure 2 (A), Figure 3, and Figure 4. From a structure that is easy to forge with two layers of stapled short fiber random web l12b as the outer layer, to one that forms the outermost layer of short fiber random web jli2b as shown in Figures s2 (b) and (c). A plurality of long fibers IIi+2m and a plurality of short fiber random webs jm2
A variety of structures can be adopted, including one in which the elements b and b are alternately arranged. Furthermore, it is essential that the above-mentioned Chion Junk I/IAjIi and the short fiber random web layer are physically integrated so that they are inseparable. The means of physical integration is, for example, needle punching or stitch bonding. The wick of the present invention is located adjacent to the above-mentioned heat-resistant combustion part 2 and located below -7°l.
iK, the fuel suction part 3 used in contact with the fuel suction part 3 is made of rayon, cellulose acetate, polyamide, etc., which have good fuel suction characteristics, as shown in FIG.
It may be formed from woven or cloth of fibers such as acrylic, polyester, bobbinyl, polyethylene, polypyroprene, polyvinyl chloride, wholly aromatic polyamide, microfiber, linen, wool, etc. As shown in Fig. 2, long fiber J1 with good fuel wicking properties is used.
The short fiber random web JIi 13b may be physically integrated into the fuel suction section 3', which is integrated and connected 4 by sewing or the like. The shape of the wick can be flat to match the combustion appliance.
It can also be cylindrical as shown in FIGS. 3 and 4. In the figure, 5 indicates the heat-resistant combustion section 2 and the fuel suction 113 (3'
) is a sleeve-strengthening tape with the connection part 4 covered and pasted. 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 combustors, as the combustion time becomes longer, the fuel profile in the base tank decreases, so when using a conventional wick, the fuel suction rate gradually decreases, the firepower weakens, or the fire extinguishes naturally. There were times when I would do something like that. However, since the wick of the present invention has a heat-resistant combustion part and a high suction speed, it is possible to continue supplying fuel to the combustion part at a constant rate even if the fuel liquid direction decreases, so the above-mentioned disadvantages can be avoided. I'm excited about evasion. In addition, the core feature of the present invention is that it has a high fuel suction rate, which makes it possible to generate a high calorific value, and also allows the vertical flow of liquid fuel into the tank and the height to the combustion part to be large. This also eliminates the risk of the liquid fuel being heated to high temperatures. Furthermore, the feature of the core of the present invention is that the long fiber layer 2 facilitates the uptake of fuel, and when the fire is extinguished, the fuel flows down rapidly, and as in the conventional example, the fuel is stored in the heat-resistant combustion part 2, extending the extinguishing time R. Since it is possible to speed up the extinguishing time by eliminating the disadvantages of wicking, the effect of reducing tar adhesion at the tip of the wick can also be obtained. 4.
