Description

[Detailed description of the invention] This invention is a warp-knitted interlining for combustion appliances, which improves the connection strength between the fuel suction part and the heat-resistant combustion part, and
The purpose is to increase the contact area of the connecting portion to promote improved fuel wicking and provide a knitted layer with good combustion characteristics.

Conventionally, in order to manufacture a wick for a combustion appliance, a fuel suction part made of cotton fiber or the like woven on a loom and cut into appropriate dimensions, and a heat-resistant combustion part made of glass fiber or the like are integrally joined at the top and bottom. This was made into a cylindrical core by using a flat core and overstitching the edges, or by butting it into a cylindrical shape and sewing it together, making the process complicated and varied.Moreover, there was a lot of material loss, making it expensive, and it was also difficult to weave. There is a drawback that unevenness tends to occur due to changes over time.

Therefore, in recent years, a method called raschel knitting has been used to form the fuel suction part and the heat-resistant combustion part into weft threads (when formed on a core, they become warp threads).

), while repeatedly folding the required width and approximately 40 to 7Q.
A plurality of connecting parts are provided for each mm to increase the core height dimension, and both are arranged simultaneously to form a large number of thin warp threads (when formed in the core, they become weft threads).

), a chain knitting structure has been provided at predetermined intervals, but in this case, as a means of connecting the fuel suction part and the heat-resistant combustion part, the warp threads are intertwined with each other, or each weft thread is knitted. It has been proposed that the folded parts of the core are interlocked in a comb-like pattern and chain stitched, but in the former case, the wefts on both sides are only brought into contact with each folded end surface in a butt-like manner, so that the core There are drawbacks such as partial separation due to vertical operation, uneven fuel suction, uneven combustion, poor wick verticality, and poor extinguishing.
In the latter case, the contact area between the weft yarns on both sides was relatively small, so the fuel suction characteristics were reduced, and the strength of the joint was not improved as much as expected.

The present invention was devised to improve the above-mentioned drawbacks, and examples thereof will be described below with reference to the drawings.

Reference numeral 1 denotes a fuel wicking part, in which a plurality of wicking part weft thread rows 1a and lb each made up of a plurality of threads of arbitrary thickness such as cotton having good fuel wicking properties are assembled to have a constant thickness. Each weft row 1ajb is repeatedly folded in a zigzag shape with intersecting jumps.
The folded portions on the connecting side of the wafer are repeatedly arranged in a folded manner while being separated in different steps.

On the other hand, 2 is a heat-resistant combustion section, in which a plurality of yarns of arbitrary thickness such as glass fibers with high heat resistance are gathered together to have a constant thickness, and the weft rows 2a and 2b are made short and the same. Weft row 2
When repeatedly folding C and 2d in different steps to make them longer, the respective heat-resistant combustion section weft rows 2 a and 2 b and the same weft rows 2 C and 2 d intersect with each other one by one. The heat-resistant combustion part weft rows 2 a are arranged so as to be repeatedly folded in a staggered pattern.
, 2 b , 2 C, and 2 d, the respective tips of the uneven folded parts 2 a ′, 2 b ′, 2 C ′, 2 d ′ d, the fuel suction part wefts 1 a, 1 b (7) uneven folded parts 1
a', 1 a".

1 b' and 1 b'' are arranged intertwined with each other so as to cause slight polymerization, and this overlapping part and other appropriate places are connected to the warp threads 3.
3. It is knitted with multiple rows of chain stitches at predetermined intervals.

In the figure, 4 indicates weft rows 2 a and 2 at the edge of the heat-resistant combustion section 2.
Cut 4a so that the ears of groups b, 2C, and 2d are trimmed evenly.
It is a fluff-like part formed by cutting, and the shape of the tip part can be arbitrarily processed such as uneven, serrated, or scattered.

In the illustrated example, both parts are connected in two different levels, but it is also possible to have three or more levels if necessary, and the number of yarns and the thickness of the threads in the different levels can be freely selected. It goes without saying that this can be done, but in any case, the threads at the connection part between the fuel suction part 1 and the heat-resistant combustion part 2 are arranged at different levels, and the folded ends of this connection part are slightly polymerized with each other. The gist of this is to knit it in a chain stitch.

To make the interlining fabric knitted as described above into a flat core, overlock both edges of each single piece as appropriate, and to make a cylindrical core, both ends of each single piece are wound and joined. As shown in the figure, a reinforcing tape 5 can also be attached to the outer circumferential surface or inner circumferential surface of the joint.

(When using it as a flat core, you can attach reinforcing tape to one or both sides of the connection part.

) Also, as a means of smoothly bending and stretching the combustion wicking part 1 when raising and lowering the core, the knitting warp is omitted at the appropriate width in the lower part as shown in Fig. 4, and only the weft threads 1a and lb are used. Alternatively, as shown in FIG. 5, a plurality of vertically divided parts 7, 7 may be provided at appropriate intervals while processing the warp threads 3 to prevent them from fraying on the combustion suction part 1, as shown in FIG. good.

In the former case, the shape tends to be distorted and the dimensions become irregular during core forming, so the shaping warps 8, 8 are used as low-cost waste threads in advance along with other warps 3, 3, etc. If the stitches are removed during the final process after knitting, there will be no defects such as deformation during the core manufacturing process, and the finished dimensions will be stable.

In addition, if the warp threads 3a at the joint between the fuel suction section 1 and the heat-resistant combustion section 2 are made of polyamide fiber, they will have excellent heat and abrasion resistance, and will avoid drawbacks such as the section breaking and coming apart even during long-term use. It can be prevented.

As described above, in the present invention, the plurality of weft thread rows of the fuel suction section 1 and the heat-resistant combustion section 2 are folded and arranged in different steps, and are interwoven with each other so that each folded tip of the connection section is slightly polymerized. In addition, since the overlapping part is also knitted with warp threads 3 and 3, the connection part is noticeable 1, which is reinforced and occurs when repeating 1. Sucking
In addition to completely preventing various troubles due to poor fuel suction due to loosening or separation of the connecting part of the combustion part 2, and malfunction of the upper and lower parts, this connection overlap part Each weft 1a, lb clay 2a, 2b, 2C, 2d
Because they are polymerized in different steps, the thickness of the polymerized part increases extremely, so it can be prevented from IL, and it is also possible to bend the tube in the vertical direction. (7), which can be installed without creating a local gap, and can also be used with a small-diameter cylinder core without causing bending. According to the original proposal, the connecting parts of the fuel suction part 1 and the fuel combustion part 2 are overlapped and connected at different levels: 1) Therefore, they are connected in a 4'E comb shape. Since the contact area between the two parts is significantly increased compared to the conventional one, which promotes fuel suction, it is also possible to manufacture a core with a high overall height.

The results of a comparative combustion test between the cylindrical wick of the present example and a cylindrical wick connected in a comb shape with the same diameter are shown below. Stove 2, core diameter 95mm Core height Fuel suction part i7Qmm Heat resistant combustion part 35mm 3o Connecting means (7

As mentioned above, in the present embodiment, the amount of fuel consumption bottle is increased compared to the 5E product. It is a device with obvious practical effects that not only eliminates uneven combustion and improves combustion characteristics, but also enables mass production of highly reliable products that can withstand long-term use.
