Description

Method for producing flat carbon fiber heating wire with few electromagnetic waves and flat carbon fiber heating wire manufactured by the above method {CRABON FIBER}

The present invention relates to a method of weaving a flat carbon fiber heating wire having a low electromagnetic wave and a flat carbon fiber heating wire.

The present invention relates to a method of weaving a planar carbon heating wire and a planar carbon heating wire with few electromagnetic waves. Carbon heating wire refers to a heating wire made of carbon as a raw material. The conventional carbon heating wire is made of a PVC material or a silicon material, and is manufactured in the same form as a general heating wire, and a small amount of nanocarbon is made of PVC or silicon to make use of the carbon material. Was put in.

In the case of Korean Utility Model Application No. 20-1999-0013291 shown in FIG. In comparison with the carbon heating wire, the conventional carbon heating wire can be seen to be manufactured in the form of a thick cross section.

That is, the conventional heating wire is wrapped with an insulator on the outside because it has to be insulated, and in many cases, the cross section is manufactured in a round shape for the convenience of manufacturing. The insulation layer is essential because the current through the hot wire increases, especially in the case of thickening.

In addition, the conventional carbon heating wire is difficult to manufacture in that way even if the cross section has a square or other shape, and the final product has a certain height (thickness), so even if it is a square cross section, The thicknesses were so similar that there was no reason for the cross section to be different.

However, in order to manufacture a product with such a hot wire, in order to prevent the thickness of the hot wire itself from being a problem, only a thick product should be used so that the use of the electric mat is limited.

In other words, even if it is used for blankets and clothes to cover, the thickness of the heating wire itself makes the product not only heavy, but also the blankets to cover are often crumpled when covered, and the clothes often have to bend with movement. Due to its rigidity, it is difficult to use because it is difficult to fold, so the conventional heating wire is used only where it can be buried with a certain thickness such as an electric mat. In addition, since such heating wire should not be damaged, washing was difficult. In addition, these hot wires often had to use a separate fixing device to fix the clothes.

An object of the present invention is to provide a carbon heating wire that can be used as a laundry in order to overcome the drawbacks described above, and can be used for many purposes such as blankets, clothes, gloves, sheets, etc. in addition to mats.

In order to achieve the above object to provide a flat carbon heating wire

A basic heating wire made of a plurality of carbon fibers that heats when a direct current is applied

It is composed of a structural yarn for winding around the basic heating wire to maintain the overall shape of the flat carbon heating wire and a coating layer formed between and outside the basic heating wire and the structural yarn,

The rescuer connects several circles and moves along the path formed by the outer edge of the circle. After moving the lower half circle of the circle, the next circle moves the upper half circle so that it is wound around the center of the circle and wound. It is supplied with the same tension from the center of the circle, so that the structured worker moves in a flat form while winding the basic heating wire to form a flat shape.

The coating layer is passed through a wire woven with a basic heating wire and a structural yarn through an aqueous emulsified resin to allow the resin to penetrate between the basic heating wire and the structural yarn and to the outside, and completely dried at 70 to 80 degrees Celsius for 12 to 14 hours, and then It may be ironed to 110 to 150 degrees of heat.

 The structural yarns may be flame retardant fibers spun by mixing a flame retardant material in a polyester chip.

 The calorific value of the planar carbon heating wire may be determined by the number of strands of carbon fibers entering the basic heating wire.

It is easy to bend by the heating wire as described above has the effect of providing a heating wire that is easy to wash and easy to control the heat generation.

1 is a view showing a conventional hot wire structure
2 shows a heating wire according to the present invention;
3 is a diagram illustrating a process of manufacturing a heating wire according to the present invention.
4 to 6 show one embodiment for manufacturing a heating wire according to the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Figure 2 is a photograph showing an embodiment of a product according to the present invention. In the photograph of FIG. 2, the black portion is the basic heating wire 21 of the carbon material and the blue portion is the structural yarn 22. Structural yarn 22 refers to a yarn that is woven together with a carbon hot wire to produce a carbon hot wire according to the present invention to make the shape of the carbon hot wire into a planar shape and make a mechanical structure. Rescuers can use a variety of yarn, flame retardant yarn, flame retardant yarn, etc. can be used mainly.

The conventional heating wire is wrapped in an insulator to be insulated from the outside and the heating wire is concentrated in the center as shown in FIG. This is because the heating wire embedded in the mat mainly uses alternating current to generate high heat, and in the case of using direct current, the heat generation is small, and thus the utility as an electric mat decreases. When using alternating current, electromagnetic waves are generated. After sleeping at home, they often felt warm but did not feel fatigued or had a tingling feeling of electricity coming into their body.

However, the carbon heating wire according to the present invention should use a direct current, and even if direct current is used, the heat generation of the carbon heating wire is higher than that of other heating wires, so there is no problem. Since it is not required, there is no problem even when using direct current.

In addition, since direct current is used, there is no risk of fire, and since it is woven like a thread, there is no problem of a short circuit even after washing. Particularly, the existing heating wire has a risk of leakage when there is damage to a part of the heating wire, but the heating wire according to the present invention does not have a risk of fire or leakage because only the output is lowered even if a part of the heating wire is broken.

In addition, as shown in Figure 6 there is little thickness it is difficult to know whether it is used, as well as it is possible to sew and fix with a thread.

In addition, since the basic heating wire 21 is woven by using a plurality of heating wires as a single thread as shown in the picture, if the number or thickness of the heating wires are adjusted, the electrical resistance can be easily adjusted to control the amount of heat generated. . Conventional carbon heating wire is to control the amount of heat generated by adjusting the size of the cross-section, but it is possible to adjust more finely by the number of heating wire.

It is preferable to use a fiber made of polyester material as the structural yarn 22, because the fusion point of the polyester fiber is high and flexible, but it is possible to use a flame retardant yarn mixed with a flame retardant mixed with a polyester chip.

However, when manufacturing carbon hot wire as a structural yarn using such flame retardant yarns, it is good to heat the yarn to about 210 to 220 degrees Celsius, in order to soften the yarn as much as possible.

Figure 3 shows the manufacturing process of the planar carbon heating wire according to the present invention.

Fig. 4 shows the arrangement and movement direction of the basic hot wire and the structural yarn for weaving in a planar shape. Carbon heating wire used for basic heating wire has a difference in strength compared to polyester fiber, so even if weaving in a plane, it cannot rotate and weave like ordinary fiber. When the carbon fiber wire is rotated like ordinary fiber, the carbon wire can be broken or the resistance can be changed by the tensile force. Therefore, the carbon wire can be fixed around the carbon wire in a fixed position so that it can be manufactured under the same tension. Let other fibers move. In addition, in the weaving machine to raise the metal rod to the position provided with the rescuer to maintain the same tension until weaving with the rescuer.

In the figure, after placing the carbon hot wire at the positions a and b, which are the centers of the circles, a proper number of structural yarns are positioned around the circles. The number of structural yarn may vary depending on the type of the final heating wire. In order to make the carbon heating wire of FIG. 2, six yarns are supplied along the same path as in FIG. 3 while supplying two basic heating wires as shown in FIG. Weaving while moving.

In Figure 4, one structural worker moves along the outside of the quadrant of the circle, and moves according to the attached number. In other words, if you start the movement in the upper right part of the circle on the lower right, it moves in the order of numbers and comes back to it again. .

There may be a number of ways of weaving a structural yarn around the basic heating wire, but the difference from the conventional manufacturing method of weaving fabric or thread is that in the present invention, the basic heating wire is not rotated and only the structural yarn is rotated in the same manner as the conventional heating wire. The fabric is rotated and woven around.

Therefore, the method of weaving the structure yarn around the basic heating line may be a conventional weaving method. In the state where several circles are in contact with each other, they move along the outer circumference of the circle, and the ends and the circles should not be attached to each other. In Fig. 4, the circles at the right end were separated from each other. In addition, if one circle moves along the outer circumference of the lower half circle, the adjacent circle moves along the outer circumference of the right semicircle and the primary heating wire is always supplied from the center of the circle.

The woven carbon hot wire is coated in order to make it flexible, to maintain tensile strength, to wash, and to prevent the exothermic performance from being degraded by moisture infiltration.

To this end, the heating wire after the weaving process is emulsified resin (PE, PP, PET, etc.) having a strong property to heat to make an aqueous resin, while maintaining the viscosity at about Vis 500 ~ 2000cps in order to facilitate the passage of carbon heating wire The carbon hot wire is precipitated and passed through. At this time, the plane heating wire is precipitated in the resin so that the resin penetrates deeply into the plane heating wire, and then the flat heating wire with the resin is passed through the rubber roller.

That is, the resin is to fill the gap between the basic heating wire and the structural yarn, unlike the conventional heating wire does not use an insulating material having a high insulation performance.

Afterwards, when ironed with heat of 110 to 150 degrees Celsius after 3 to 4 hours of drying at 70 to 80 degrees Celsius, the carbon wire is completely coated with a resin and the surface becomes smooth.

Figure 6 shows an embodiment of the carbon heating wire according to the present invention, the carbon heating wire according to the present invention is composed of a plurality of strands, even if sewing because of the strength of the carbon fiber itself, the needle slips on the carbon heating wire to sew sideways Because it is made or between the carbon fiber strands there is no performance degradation by sewing is possible by fixing by sewing.
