Abstract

The present invention relates to a heating fabric using carbon yarn. According to the present invention, a conductive yarn is arranged only in a part of the fabric as warp and a corresponding conductive yarn portion is woven in a multi-woven layer so that an upper conductive layer and a lower conductive layer are formed and an insulating layer is formed between the upper and lower conductive layers. The upper and lower conductive layers have current flow directions opposite to each other and conductive heating wires are alternately connected to the upper and lower electrode layers. Accordingly, magnetic fields are formed oppositely throughout the fabric to be canceled, thereby preventing electromagnetic waves from being generated. Moreover, the conductive yarn is located only in a portion while minimizing the area of the conductive yarn in the entire fabric, and thus the risk of damage or breakage of the heating fabric during processing, such as sewing and the like, and daily use can be reduced.

As for the heating fabric, as shown in FIGS. 1 to 3, carbon yarn 11 is used as a weft, and conductive yarn 13 is used as a warp, but the central part is a general fiber yarn 12a, 12b as a warp, and the amount of fabric It is woven using the conductive yarn 13 as a slope only at the end, and heat is generated while the power supplied through the conductive yarn 13 is applied to the carbon yarn 11 serving as a resistance.

In the drawing, H denotes a heating unit, E denotes a power supply unit,

However, the above-described heating fabric has a problem in that a magnetic field generated by an electric current causes an induced current to be generated in the human body, thereby interfering with the normal flow of potassium or sodium, which facilitates metabolism, and thus adversely affects health.

Accordingly, a technology for suppressing the generation of electromagnetic waves by making magnetic fields cancel each other has been developed by the applicant of the present invention and registered in Korean Patent Registration No. 10-1658330, and the prior art will be described with reference to FIGS. 4 to 6.

In the prior art, as shown in FIG. 4, the heating wire (2) (2') formed of carbon yarn is used as a weft, but is used to be arranged at regular intervals with general fiber yarn, and conductive yarn (5) (5') made of a metal material ( 6) (6`) is used as a warp, but the center of the fabric is made of ordinary fiber yarn, and a plurality of the conductive yarns are arranged at regular intervals at both ends of the fabric and weaving, but the heating wire is among a plurality of conductive yarns located on both sides. Weaving so as to contact only one and the next heating wire is in opposite contact with each other, and insulating layers 7 and 7 ′ are positioned between the conductive wire and the heating wire that are not in contact with each other.

As shown in FIG. 5, in the fabric woven in this way, the current flows alternately in each heating wire, and currents in opposite directions flow to the conductive yarns located on both sides of the fabric, as shown in FIG. According to Fer's right-hand screw rule, the magnetic field is formed in the opposite direction and is canceled to suppress the generation of electromagnetic waves.

However, even in the case of the prior art, as shown in FIG. 7, the magnetic field is canceled at the center portion of the fabric, that is, the E2 portion, but since the magnetic field leaks to both edges, that is, the portion E1, it was impossible to completely cancel the magnetic field.

An object of the present invention for solving the above problems is to arrange a conductive yarn at a ramp in only a part of the fabric and weave the conductive yarn portion in a multi-weave, thereby forming an upper conductive layer and a lower conductive layer, and between the upper and lower conductive layers. An insulating layer is formed, but the upper and lower conductive layers have the opposite current flow direction, and the conductive hot wires are alternately connected to the upper and lower electrode layers, thereby forming an opposite magnetic field across the fabric and canceling the electromagnetic wave. It is to provide a heat-generating fabric that prevents the occurrence of heat.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The heating fabric according to the present invention is a woven fabric including a conductive heating wire 112 used as a weft yarn and an upper/lower conductive transfer yarn 114 and 116 used as a warp, as shown in FIGS. The upper and lower conductive yarns 114 and 116 are positioned only on a part of the fabric to form a multiwoven to form the upper conductive layer 100 and the lower conductive layer 200, but the heating wires 112 are alternately One of the upper and lower conductive yarns 114 and 116 is brought into contact, and an insulating layer 300 is formed between the upper and lower conductive layers 100 and 200.

In the above, the insulating layer 300 formed between the upper and lower conductive layers 100 and 200 is sandwiched between the upper and lower conductive layers 100 and 200 formed in a double weave with an insulating material having a predetermined width such as synthetic resin. It can be formed by putting it in.

In addition, as another example of the insulating layer 300, an insulating thread 118 is further disposed at a portion where the upper and lower conductive threads 114 and 116 are located, and the upper conductive layer 100 is woven with the upper conductive thread 114. ), the insulating layer 300 woven with the insulating thread 118, and the lower insulating layer 200 woven with the lower conductive thread 116.

A woven fabric including conductive heating wire 112 used as the weft yarn, upper/lower conductive yarn 114 and 116 used as a warp, and insulating yarn 118 used as a warp, insulated from the upper conductive yarn 114 The yarn 118 is positioned only on a portion of the fabric, and the upper and lower conductive yarns 114 and 116 are respectively positioned at the upper and lower portions around the insulating yarn 118, so that the upper and lower conductive yarns 114 and 116 ) And only the portion where the insulating yarn 118 is located is woven in a triple weave, but the heating wire 112 is alternately intersected with one of the upper/lower conductive yarns 114 and 116.

In the above configuration, the heating wire used as the weft is carbon yarn, and the weft yarn is only the heating wire 112 or a mixture of the heating wire 112 and the general fiber yarn 119, but the heating wire 112 is It is used at regular intervals.

The heating wire 112 is formed of a conductive carbon fiber material, and serves as a resistance according to the flow of current so that heat can be generated.

In addition, the heating wire 112 is woven by crossing only the upper conductive yarn 114 or the lower conductive yarn 116, and the insulating yarn 118 is woven by skipping, and the general fiber yarn 119 used as the weft is the insulating yarn ( 118) is also woven.

On the other hand, in one side of the warp, the upper/lower conductor and the insulating yarn are located in an inclined manner, and a general fiber yarn 119 is used for the remaining part.

At this time, the insulating yarn 118 is made of a wide resin fiber.

After the weft and warp are arranged in this way, the heating wire 112, the general fiber yarn 119, and the heating wire 112 are sequentially supplied to the weft, and the first supplied heating wire 112 is the upper conductive yarn ( 114), and the next supplied general fiber yarn 119 is woven with the insulating yarn 118 at the edge of the fabric, and the next supplied hot wire 112 is woven with the lower conductive yarn 116 at the edge of the fabric After that, the general fiber yarn 119 is used as weft yarn a plurality of times, and weaving with the upper conductive yarn 114, the insulating yarn 118 and the lower conductive yarn 116 in order, respectively, and the heating wire 112 is again used as a weft yarn. This is repeated so that the woven fabric has a triple structure of the upper conductive layer 100, the lower conductive layer 200, and the insulating layer 300.

In the drawing, A1 denotes an intersection of the hot wire and the upper conductive yarn, and A2 denotes the intersection of the hot wire and the lower conductive yarn.

A detailed look at the action of the present invention formed as described above is as follows.

First, when power is supplied by connecting the'+' and'-' wires to the upper conductive thread 114 and the lower conductive thread 116, respectively, current is applied in opposite directions to the upper conductive thread 114 and the lower conductive thread 116. It flows, and currents in opposite directions flow to each of the heating wires 112 connected to the upper and lower conductive threads 114 and 116, respectively.

In this way, since the current flow directions are opposite to each other, the magnetic field is also formed in opposite directions to cancel the magnetic field, thereby suppressing the generation of electromagnetic waves in the entire fabric.

In addition, since the insulating yarn blocks between the upper conductive yarn and the lower conductive yarn, the process of inserting a separate insulator for insulation between the upper and lower conductive yarns after weaving the fabric is omitted. It is very difficult to put in, so it will greatly improve your productivity.

In addition, since the upper/lower conductive thread 116 uses not only one strand, but several strands, even if any one of them is disconnected, current flows, so that heat is continuously maintained.

In this way, the present invention is to offset the magnetic field by the current flowing in different directions to the upper/lower conductive yarns 114 and 116 to cancel the magnetic field over the entire fabric, and the upper/lower conductive yarns 114 and 116 are insulating yarns ( 118) makes it possible to use it safely because it is completely insulated.
