Description

[Detailed description of the invention] The present invention is a warp-knitted interlining for combustion appliances.
It prevents fraying at the cut part, improves dimensional stability, strengthens the joint part in the vertical direction (direction when formed into a flat core or cylindrical core), and improves the circumferential direction such as thickness and cylindrical diameter. A flat or cylindrical formation that aims to mass-produce uniform products by shortening the process while eliminating variations in fuel suction at each part and improving core characteristics such as smoothing the fire rotation in the initial stage of combustion. This relates to strengthening the edge of the vertical joint of the core.

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 one above the other. The cylindrical core was manufactured by using a flat core and overstitching the edges, or by butt-sewing it into a cylindrical shape, which required a complex and varied process, resulting in a lot of material loss, which inevitably led to high costs. There was a drawback that unevenness was likely to occur due to changes over time during weaving.

Therefore, in recent years, a warp knitting machine called a Russell knitting machine has been used to repeatedly fold the fuel suction part and the heat-resistant combustion part by repeatedly turning the weft (when formed on the core, it becomes the warp) and about 40 to 7
Knitting in which multiple connections are provided for each Qmm to increase the core height dimension, and both are arranged simultaneously and chain stitched at required intervals using a large number of thin warp threads (which become weft threads when formed on the core). Kaishin has been developed and offered, but in this case, when cutting into individual pieces, the separated warp threads tend to fray, and it is difficult to treat the ends.As an example of a countermeasure, the warp threads are melted by heat. The conventional method used was to knit with soft fibers and then weld them by heat cutting, but this method had the disadvantage of poor heat resistance, so the warp yarns near the burning part melted, the seams separated from side to side, and the core came apart. When a combustion appliance falls over, it is not desirable because the amount of oil it falls over increases and there is a risk that the fire cannot be extinguished.Also, attempts have been made to prevent fraying by applying adhesive, but when the adhesive dries. The applied part may harden or shrink, causing thickness and
None of these cases were preferable, as the cylindrical diameter tends to vary, which tends to cause uneven fuel suction, and in addition, the fire rate during initial ignition is poor, and impurities such as tar tend to adhere.

In addition to the above method, another method is to use zigzag stitching to reinforce the seam over a wide width, but in this case, this part becomes too stiff than other parts and the thickness is uneven. In addition to the above-mentioned drawbacks, there were other disadvantages such as uneven and uneven operation of the core.

The present invention has been devised in view of the above points, and examples thereof will be described below with reference to the drawings.

2 is a heat-resistant combustion section composed of combustion section wefts 2a such as glass fibers with high heat resistance, and both of them are separately assembled into a single weight or multiple wefts of suitable thickness. When using a warp knitting machine to knit multiple rows of chain stitches at predetermined intervals with warp threads 3, 3, etc. while simultaneously repeatedly folding and arranging them, flat core or cylindrical Required effective length L1 for each single piece formed on the core (Figure 1 shows an example of folding back one end. When cutting the warp threads, if it is on the side that does not easily get tangled, it can be left cut without any problem. some) width,
A folded blank section 5 knitted by chain stitch or the like using only the warps 3, 3 is provided outside one side end (upper side in Fig. 1) of the knitted part 4 formed by the warps 3, 3 and each weft 1a, 2a, and further The warp yarns 3, 3 and the respective weft yarns 1a, 2
In addition to connecting and providing a fitting knitted part 6 knitted with a,
Leaving an appropriate middle ground knitting end 4a at the end edge of the knitting part 4, warp threads 3 having a width that matches the width of the fitting knitting part 6 are placed inside the knitting end 4a.
A fitted blank section 6a knitted only with warp threads 3 is provided, and furthermore, a cutting blank section 7 knitted only with warp threads 3 and 3 is provided on the outside of this blank section 6a.
The knitted parts are sequentially and continuously knitted as one unit, and each cutting blank part 7 is cut and separated into single pieces with a unique unit length L2, and the fitting knitted part 6 of each single piece is folded back and blank Fold it back from the part 5 and connect it by fitting it to the blank part 6a to be fitted, and then sew it at the appropriate places or fix it by line joining 8 integrally with adhesive etc. When making a flat core, both ends of the single piece are All you have to do is sew them together, and to form a cylindrical core, you can abut both ends of a single piece into a cylindrical shape, and then sew or glue the seams at the appropriate places to form a line joint 9. be.

It is also possible to fit and connect the wires 8 and 8a to the wires 8 and 8a.

Furthermore, although not shown in the drawings, it is of course possible to attach any reinforcing tape to one or both surfaces of the core (inner circumferential surface or outer circumferential surface in the case of a cylindrical core) as necessary.

In addition, 2b in the figure is the combustion part weft 2a at the upper edge of the heat-resistant combustion part 2.
This is a fluff-like part formed by cutting the folded ears of the group so that they are aligned, and 10 indicates the connection part between the fuel suction part 1 and the heat-resistant combustion part 2.

Since the present invention is configured as described above, the following effects can be obtained.

(1) Since the ends of each single piece are not butted and joined as in the past, the warp threads do not become frayed, and the weft threads do not come apart.

(2) The mated blank part 6 corresponding to the mating knitted part 6 (6b)
a (6C) and line-jointly fix each weft 1a.
, 2a do not overlap or separate, so that they can be manufactured uniformly without variations in thickness or cylindrical diameter.

(3) The longitudinal seam formed in the core is strengthened, and each fitting part is further strengthened by the warp threads 3 of the fitted blank part 6a (6C).
, 3, the connecting portion 10 and each longitudinal joint portion can withstand long-term use without bursting or separating.

(4) In the circumferential direction, there are no gaps or unnecessary overlaps at each vertical joint, so the fuel is sucked up evenly, and the fire speed at the time of initial ignition is improved, resulting in rapid Stable combustion can be obtained and tar adhesion can be prevented.

(5) Since the joint part is easy to bend into a cylindrical shape without becoming too stiff than the ground knitting part, it can be made to be in uniform contact with the core holding metal fitting.

(6) Unlike conventional cores, complicated reinforcing means for strengthening the joints at the ends of the cores are not required, simplifying and shortening the process, and enabling mass production with high efficiency.

In addition, various methods can be used to join the seams, and as shown in the figure, each seam is not butted, so even in the case of suturing, narrow zigzag sutures can be used to accurately and without causing hot spots. In addition to being able to join, key points of the blank knitted stitching threads of each warp thread 3 and 3 may be sewn in series so as to be perpendicular to the warp threads. This eliminates various drawbacks such as the stiffness of the core becoming too strong, the thickness becoming uneven and uneven, and the lower -L operation of the core becoming smooth and uneven, as well as other important points at various joints. This method is not necessarily limited, and can also be carried out by bonding and fixing them with a suitable adhesive.

As described above, the present invention can provide an excellent wick for combustion appliances that eliminates the conventional drawbacks and provides many practical effects.
