Abstract

PURPOSE:To provide a wick for a combustion equipment showing a superior sucking efficiency of fuel in a simple and inexpensive manner by a method wherein the sucking of fuel is carried out mainly through many threads of large size, secondly carried out with threads and adjoining threads and at the same time surplus fuel sucked through the threads is held by a web fabric. CONSTITUTION:A web fabric 1 is provided with a plurality of thread insertion holes 3 having some threads 2 of optional size inserted therethrough in sequence. Linear threads 5 are formed on a surface 4 of the web fabric 1 and at the same time ring-like threads 7 are formed at a rear surface 6. The linear threads 5 are engaged with the ring threads 7 in sequence so as to make a plurality of stiches 8 and then they are sawn. In addition, a plurality of adjoining threads 9 having optional size are sawn with some small clearances 10 being set in the same manner as the sawing of the stiches 8 of the threads 2 against the web fabric 1. Thus, the threads 21 of large size with a fuel suction performance are disposed in parallel in a longitudinal direction of the small clearance 10 at an inner layer 20 of the web fabric 1 within the small clearance 10 so as to form the inner layer suction part 22.

Description

Description: [0001] The present invention relates to an interlining for combustion appliances that mainly use kerosene as fuel, such as oil stoves and oil stoves. [0002] Conventionally, a heat-resistant combustion section made of glass fiber or a thick fabric made of a blend of glass fiber and carbon fiber is connected to the upper part of a fuel suction part made of a thick fabric made of cotton thread or a blend of cotton and rayon. Interlining materials for combustion appliances configured in a circular or cylindrical shape are known. [0003] Also, thick warp threads made of glass, cotton, or other fibers are always bundled or twisted, are arranged horizontally, and a felt-like fiber layer of glass fiber is polymerized on both the front and back sides, and the glass fibers of the felt-like fiber layer are polymerized by needle punching. For example, the interlining for combustion appliances, which is made of thick warp threads arranged horizontally in parallel, is

filed an application for interlining for combustion appliances that is sewn with a small gap 40. Problems to be Solved by the Invention The former interlining for combustion appliances has the following drawbacks. [0006] Production relies on old-fashioned special looms, resulting in extremely low productivity and inefficiency. [0007] In particular, the fuel suction section has a warp made of very thick cotton yarn, such as 10 count 8-strand yarn, and is narrow and has a special structure, so the number of looms is limited and the area used is large. As a result, there is often a shortage of supply. [0008] In addition, dimensional variations tend to occur, resulting in a high defective rate, and in addition, problems such as shrinkage during use, binding to the core guide tube of the instrument, and failure to raise and lower the core are likely to occur. Furthermore, fraying is likely to occur during cutting, and it is necessary to perform fray-prevention processing such as oversewing the edges or applying adhesive. [0010] Also, the interlacing of the warp and weft yarns deteriorates the efficiency of fuel suction. Furthermore, the latter interlining for combustion appliances is made by simply bundling or twisting glass, cotton, or other fibers and arranging thick warp threads horizontally, and polymerizing felt-like fiber layers of glass fibers on both the front and back surfaces. Since the glass fibers of the felt fiber layer are entwined with the horizontally parallel thick warp threads by needle punching, the adjacent thick warp threads are separated, and further the parallel thick warp threads and the felt fiber layer of glass fibers come into contact with or separate from each other. However, due to deformation of the warp threads, unstable dimensions when the device is attached, etc., the fuel suction effect is poor and the flame is not evenly distributed. [0012] In addition, FIGS. 13, 14, which the applicant previously applied,
The fuel suction of the wick for a combustion appliance shown in FIG. 15 is carried out by a capillary tube formed by a large number of thick threads 32, but since these form a ring-shaped thread section 7 and are bulky, they can be arranged at a constant width. Since the number of threads is limited, there is a limit to the fuel suction capacity. [0013] Also, the thick thread count 32 is 0.5 in English thread count.
~10 thick yarn, so unevenness is formed on the surface of the interlining by the linear yarn portions 35 and ring-shaped yarn portions 37, resulting in poor adhesion to combustion appliances and oil leakage when falling over. There was a problem. [0014] This invention solves the above-mentioned problems, has good fuel wicking efficiency, allows mass production of non-woven fabric interlining at low cost, and also makes it possible to use common materials, making inventory management easy. In addition, the dimensional stability is good, there is no problem with incorrect lifting of the wick, and the height (distance) from the liquid fuel level to the combustion part can be increased, so that the liquid fuel can be heated to a high temperature. It can prevent it from being heated to high temperatures,
The object of the present invention is to obtain interlining for combustion appliances that is convenient to use and can continue safe combustion. [Means for Solving the Problems] In order to achieve the above object, the interlining for a combustion appliance of the present invention has a thread insertion hole 3 through which a thread 2 of an arbitrary thickness is inserted into a web fabric 1. , 3 .

The number 00 is preferable, and the number 5 to 40 is more preferable. In addition, since the interlining for a combustion appliance is constructed by knitting the knitting thread 12 onto the web fabric 1, it is necessary to prevent the knitting thread 12 from fraying at the cutting part 11, so that the surface of the knitting thread 12 is A fluff portion 13 is provided to prevent slipping (see FIG. 9), and a knitted yarn 12 is provided.
The cut portion 1 is mixed with a heat-melt thread 14 (see FIG. 10) or coated with a heat-melt adhesive 15 (see FIG. 11).

It varies depending on the specifications, the intended suction capacity of the interlining for combustion appliances, the required thickness, etc. [0021] The stitched yarn 12 can also be colored in an appropriate color. By coloring the knitted yarn 12, it is possible to easily identify various types of interlining and improve the aesthetic appearance of the interlining. Furthermore, by applying a water-repellent finish to the knitted yarn 12 and the thick yarn 21, even if water gets mixed into the fuel, the interlining will absorb the water to the top of the wick, causing poor combustion. Things will disappear. If the web fabric 1 is treated with water repellent treatment, this effect will be further enhanced.

It is. [0032] Also, unlike conventional products, it is not necessary to form a narrow cloth that corresponds to the dimensions of the combustion appliance used, but it can be manufactured in a wide width shape with high efficiency, making it possible to significantly reduce costs. In addition, there is no need to prepare many types of interlinings for combustion appliances each having a woven cloth according to the type of combustion appliance used, and it is possible to obtain many types of wicks for combustion appliances by simply changing the cutting dimensions. This makes it possible to standardize materials and facilitate inventory management such as reducing inventory.
