Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wick for liquid combustion appliances such as oil stoves and oil stoves, and a method for manufacturing the same.

In order to manufacture conventional woven cores, the required developed length of a flat or cylindrical core is woven with a constant weaving width, and the woven fabric part is woven with warp and weft yarns of cotton fibers, etc., and the fabric part is woven with warp yarns only. A fuel wicking core material made by repeating and continuous weaving of bending and stretching parts formed in a shape in the longitudinal direction is cut into short pieces, and a heat-resistant combustion wick woven or knitted with heat-resistant fibers such as glass fibers is connected to the top of this material. This was done by making a flat core, or by butt-stitching the edges on both sides to form a cylindrical core.As a result, the swing width of the weft during weaving was longer, and the number of revolutions of the weaving machine was approximately 60. Since it is limited to ~120 times/min, it becomes inefficient and costly, and
There were various drawbacks such as dimensional variations due to changes over time, and the wider the width, the greater the shrinkage rate during chemical treatment, resulting in a higher defect rate.

The present invention has been made to eliminate the above-mentioned drawbacks, and embodiments thereof will be described below with reference to the drawings. ■ is a twisted wicking core woven from fibers such as cotton fibers that have good wicking properties for liquid fuel.
The upper part 1a and the lower end part 1 are made of woven fabric woven in warp and weft.
1A', 1A'', 1A divided into a plurality of sections with a weaving width l divided into a plurality of pieces of arbitrary width. ″′・1A
Arrange any number of ``'' in parallel in the horizontal direction and sew them together 2.2
a and form it into the required length L, and then integrally sew 4 a heat-resistant combustion core 3 woven or knitted with heat-resistant fibers such as glass fibers onto the upper part of this core to use it as a flat core, or furthermore, use it as a flat core. are butt-sewn together 5 and processed into a reed-shaped core. In the figure, 6 is a reinforcing tape.

In addition, the dimension of the weaving width l of a single section is 1/2 to the required developed length L.
It may be set arbitrarily within the range of 1/6. Note that the connecting part 2n of the lower end hem part 1n' can be used as only the main part, and the rest can be left alone (not shown).

As described above, the present invention can form a conventional fuel suction wick into a desired length by connecting a plurality of short width section single pieces to a desired length.

(1) By increasing or decreasing the number of single section pieces, manufacturing can be adapted to suit the size of the core diameter, making it easy and quick to change products, and eliminating various means such as changing setups to change the weaving width of the loom. .

(2) Since the swing width of the weft threads in a single section is shortened, there is no variation in dimensions.

(3) Since the width is narrow, it can be processed efficiently with small equipment during flameproofing and waterproofing.

(4) During the chemical treatment in item (3), the shrinkage rate of the fibers is reduced because the width is narrow.

(5) Since it can be manufactured by cutting a material with a continuous short weave width, the cutting width can be reduced, and the occurrence of irregularities and cutting layers during cutting can be reduced as in the conventional method.

(6) Even when weaving flaws, unevenness, thickness unevenness, or stains occur, it is only necessary to remove a single piece of the section in that area, so there is no loss in making the entire core defective as in the conventional case.

(7) At the time of acceptance inspection, the number of sensors etc. that need to be installed as a method for inspecting thickness and weave width can be reduced, making it easier to perform automated and labor-saving inspections with compact equipment.

As another example, as shown in FIGS. 3 and 6, when sewing the section single pieces 1A', 1A", 1A"', and 1A"" square parts 1a, the appropriate places are left leaving the splits 7 and 7. If the fitting 2 is applied, elasticity is imparted to the part, so when it is attached to a combustion appliance, it is possible to prevent the lead guide cylinder from getting stuck due to changes over time, and to eliminate troubles such as the inability to move the lead up and down.

In addition, as an example of providing the above-mentioned splits, cuts 8 and 8 may be made at appropriate locations in the upper portion 1a of the woven fabric of the fuel wick 1, as shown in FIGS. 8, 9, 10, and 11. Even if it is drilled, the same effect can be obtained.

Next, the manufacturing method of the present invention will be described. Made of fibers such as cotton fibers that have good wicking properties for liquid fuel, the required developed length L of the core is divided into a plurality of sections with arbitrary widths, and the weave width is relatively narrow l or l1.
A woven fabric portion 1n woven with warp and weft yarns with dimensions of
The short fiber width material of the upper core of the fuel fabric is woven repeatedly and continuously in the longitudinal direction with a bending part 1b formed in a curtain shape using only warp threads, and a lower end resting part 1n' of the woven fabric is formed at the lower end of the bending part 1n. Cut the woven fabric part 1a slightly leaving the upper edge part C.C.
A compartment single piece 1A' with a constant length 1l or 1l1
- Divide into 1A'', 1A''', 1A''' or 1B', 1B''. (Figures 1, 2, 3, 4, 5, 6, 10, and 11 show examples of the width l obtained by dividing the required developed length L into four, and the seventh
・Figures 8 and 9 show an example of a width l1 obtained by dividing the required development length L into two. ) Next, an arbitrary number of single pieces of each section are arranged in parallel in the horizontal direction, butted and sewn integrally 2.2
A heat-resistant combustion wick 3 is formed into a fuel wick 1 with a required developed length L, and the upper edge of the fuel wick 1 is woven or knitted with heat-resistant fibers such as glass fibers and cut to a desired developed length L. A flat core can be constructed by butting and integrally sewing (4), and a cylindrical core can be constructed by butting and sewing (5) both ends of the flat core. (Refer to Figures 5, 6, 9, and 11) As mentioned above, when sewing 2 and 2a of each image single piece 1A', 1A'', 1A''', 1A''' or 1B' and 1B'', the woven fabric By leaving splits 7 and 7 at appropriate locations in the upper part 1a and sewing 2 only above and below them, elasticity can be imparted to the upper part of the woven fabric. Incisions 8, 8 may be made at appropriate locations in the upper portion 1a of the woven fabric at an arbitrary step.

In addition, before or after cutting the fuel suction wick 1 into single sections, or in the pre-process of connecting the heat-resistant combustion wick 3 to the required developed length, the combustion side is The upper part of the wick 1 may be subjected to flame retardant treatment 9 to impart heat resistance, or
As shown in Fig. 4 (B), by applying a flame retardant finish 9 to the upper part of the fuel wick 1 and a water repellent finish 10 to the lower part, a heat resistant and waterproof fuel wick can be obtained. be. In addition, Figure 4 (C
), it is also possible to apply the water repellent finish 10 to the entire fuel wick 1 and not apply the flame retardant finish 9 only to the upper part.

The above flame retardant treatment is a processing method that makes flammable organic fibers flame retardant, for example, by reacting and bonding TBPC (tetrakis droxymethyl phosphonium chloride) to cellulose fibers with a thermosetting compound such as trimethylolmelamine and urea. Use the one you made. In addition to the above-mentioned flame retardant agents, there are many others, including those using APO {tris(1-azilidenyl)phosphine oxide} ammonium salts, sodium tungstate, organic titanium compounds, and others. Furthermore, water-repellent finishing is a process that applies a thin hydrophobic coating to prevent water from penetrating fibers, paper, etc., and makes them waterproof by repelling water. There are many things you should avoid using, such as salts, silicone resins, metal soaps, waxes, fluorine compounds, and more.

It goes without saying that none of the flameproofing and water-repellent finishing mentioned above impairs the lipophilic properties of the fuel wick.

As described above, when using the manufacturing method of the present investigation, it is possible to significantly narrow the weave width and perform continuous weaving with a short width, but it can only be produced at a rotation speed of a loom with a conventional weave width of about 60 to 120/min. It is now possible to perform weaving at high speeds of rotation of about 800 to 1,600 times per minute, which was previously not possible, and it is possible to produce even and uniform products at low cost, as well as flame-retardant, water-repellent finishing, etc. This is a valuable invention with various features such as being able to be carried out arbitrarily during the manufacturing process.
