Description

Striped heating fabric having enhanced heat efficiency and heating roll screen using the same}

The present invention relates to a linear heat generating fabric with improved thermal efficiency and a heat generating roll screen using the same, and more particularly, a linear heat generating fabric having improved thermal efficiency by which carbon fiber heats due to an applied electric current for thermal function, and a heat generating using the same. Type roll screen.

The traditional linear heating fabric has a shape in which a heater wire is insulated between the pad and the pad, thereby achieving heat by heating the heater wire.

However, due to the characteristics of the linear heating element incorporating the heater wire, it has been pointed out that a problem of emitting a large amount of electromagnetic waves in the resistance heating process of the heater wire and the flexibility is remarkably inferior, and the frequency of use thereof is gradually decreasing recently.

In recent years, linear heating fabrics using carbon fiber yarns have been newly introduced, and these linear heating element fabrics have a tendency to decrease their electromagnetic wave and power consumption in the resistance heating process, and their use is gradually increasing.

By the way, the recent linear heating element is a simple weave of warp and weft yarn made of carbon fiber yarn in the form of plain weave, and still use copper wire as a conductor. This type of planar heating element is not only inflexible, but also carbon fiber yarn which promotes heat generation. Since both sides are exposed at the same ratio, it is pointed out that a large amount of unnecessary heat is released through the back surface, which is substantially not required to generate heat.

In addition, the conventional linear heating element is composed of a conductive portion through a copper wire that is significantly less flexible, and thus it is difficult to be applied to a heat-type roll screen or the like, which requires a repetitive winding and unfolding due to the warpage of the fabric. .

In addition, since the copper wire forming the conductive part does not have physical properties such as fiber yarn and carbon yarn, it is difficult to weave through a normal weaving process. Therefore, a dedicated facility for forming the conductive part and an additional inclined beam process were separately required. Due to the addition of the process and the increase in the additional costs and weaving of the product due to the manufacture of the product, as a result was pointed out the problem of lack of economic feasibility due to the expensive production cost due to the decline in production.

In addition, since a stable power supply structure is not formed in the conventional heating type roll screen, since a power line, which is a supply path of current, is drawn out directly to the heating sheet, winding of the heating sheet is difficult as well as drawing out in the power supply state. There is a problem that the appearance is damaged by the power line.

An object of the present invention devised to solve the above problems is to improve the weaving form to form a heating layer to increase the exposed area of carbon fiber yarn on the surface to achieve stable heat generation, the exposed area of the fiber yarn is increased The present invention provides a linear heat generating fabric, a heat generating roll screen using the same, and the like, by forming a heat insulating layer to achieve a stable heat insulating effect.

The above object is achieved by the following configuration provided in the present invention.

More preferably, the conductive yarn forming the conductive portion is formed by coating silver nanopowder or silver nanopowder on the fiber yarn to have conductivity by the silver nanopowder or the positive silver nanopowder.

On the other hand, the heat-generating roll screen according to the present invention,

The heat generating sheet is formed by weaving carbon fiber yarns, which are weft yarns, and warp yarns, in a main or twill weave. On both sides of the linear heat generating portion in which the heat insulation layer is formed, the linear heat generating fabrics in which the conductive portion is formed by weaving the conductive yarn inclined to the weft carbon fiber yarn in a plain weave are partitioned and arranged.

Conductive molds implying copper wires are disposed on both sides of the heating sheet, and conductive parts of each of the linear heating fabrics are connected in parallel with copper wires embedded in the mold through connecting wires, and each linear heating element distributes the current applied in the copper wires in parallel. Characterized in that configured to be authorized by.

Preferably, the winding drum is provided with a rotation wheel in which the annular terminals formed in contact with the copper wire are disposed at the outer diameter, and the fixed bracket is disposed in close contact with the annular terminal of the rotation wheel and has fixed terminals formed in contact with the power line. Thus, the copper wire and the power line are configured to form a conductive state through the rotating contact structure composed of the rotating wheel and the fixed terminal.

As described above, in the present invention, in forming a linear heat generating fabric by weaving carbon fiber yarns for heat generation and fiber yarns having relatively superior flexibility than thermal insulation and carbon fiber yarns, Or weaved by twill weave a heat generating layer having a larger exposed area of carbon fiber yarns on the surface, and a heat insulating layer having a less exposed area of carbon fiber yarns on the surface thereof.

As a result, the phenomenon in which heat is unnecessarily released to the back side is suppressed. As a result, a large amount of heat is released from the heat generating layer, and cold air conducted to the heat generating layer by the heat insulating layer is blocked, thereby having a substantially high thermal efficiency.

Further, the linear heating fabric woven in the main runner has a superior flexibility than the linear heating fabric fabric woven in the plain weave, and in the present invention, the conductive yarn is formed by coating the silver nano powder or the silver nano powder on the conductive yarn instead of the copper wire. As it adopts, it has the advantage that winding and development are easy by the superior flexibility.

In addition, since the conductive part is a bond fiber, yarn can be woven through a single weaving process and equipment together with the linear heating part, so that the additional cost of weaving and commercially available is low.

In particular, since the linear heating material is fixed to be fixed by the thermoplastic resin to be coated, or the polyurethane film to be laminated, it has a strong durability, flexibility and insulation by the thermoplastic resin or the polyurethane film fixed to the surface.

On the other hand, the heat-generating roll screen according to the present invention is the linear heating element is adopted, not only combines improved thermal efficiency and flexibility, each linear heating element formed on the heating sheet is a current in parallel through the copper wire formed on both sides of the sheet Since heat is applied to each of the linear heating element fabric is applied with the same current, through which it is possible to radiate heat evenly as a whole.

In addition, the heating sheet is applied with a current through the rotating contact structure formed between the winding drum and the fixing bracket, it is possible to select the incoming wire on the top, it is possible to supply a stable current without damaging the appearance by the power line.

Hereinafter, with reference to the accompanying drawings it will be described in detail the linear heat generating fabric, and the heat generating roll screen using the improved thermal efficiency proposed as a preferred embodiment in the present invention.

Figure 1 shows the overall configuration of the linear heating element having an improved thermal efficiency proposed as a preferred embodiment in the present invention, Figure 2 is a cross-sectional configuration of the linear heating element having an improved thermal efficiency proposed as a preferred embodiment in the present invention To show.

In addition, the linear heat generating portion 10 basically weaves the carbon fiber 12a, the weft yarn 12, and the fiber yarn 11a, the warp yarn 11, in a main or twill weave, and the surface of the carbon fiber than the back surface. A heat generating layer 10a having a large exposed area of the yarn 12a is formed, and a rear surface thereof is formed in a form in which a heat insulating layer 10b having a smaller exposed area of the carbon fiber yarn 12a is formed than the surface thereof. The linear heat generating portion 10 that is woven in a straight line is shown.

Here, the weft yarn 12 in the linear heat generating unit 10 may be mixed with carbon fiber yarn 12a and fiber yarn 12b from 1: 1 to 1: 4, the fiber yarn including a variety of fibers including PET fiber yarn The company may be adopted.

In Figures 1 and 2 showing a preferred embodiment, the five-fiber runner adopting a fiber yarn 11a as a warp 11, and a mixture of carbon fiber 12a and fiber yarn 12b as a weft yarn 12 The line-shaped heat generating fabric 10 of the fabric is shown, and if necessary, it is possible to weaving into seven pieces of runners, eight pieces of irregular runners, or twill.

As such, when the heat generating layer 10a having a large exposed area of the carbon fiber yarn 12a is formed on the surface and the heat insulating layer 10b having a small exposed area of the carbon fiber yarn 12a is formed on the surface, substantial heat generation is required.

As a result of producing the linear heating element by the present inventors in plain weave and main runners, the linear heating element 1 according to the present invention, which is woven in a main runner as compared to the linear heating element which is woven in plain weave as shown in Table 1 and FIG. It can be seen that it has a relatively high thermal efficiency when looking at the exothermic temperature or the exothermic time.

In addition, the linear heating element 1 according to the present embodiment, which is woven in a main runner, has excellent flexibility in comparison with plain weave due to its structure, and thus, when applied to a heating roll screen to be described later, there is also an advantage that stable winding and deployment are possible. .

On both sides of the linear heat generating portion 10, conductive portions 20 for applying a current to each carbon fiber yarn 12a forming the weft yarn 12 of the linear heat generating portion 10 are formed by weaving. In the example, the conductive portion 20 is formed by weaving the conductive yarn 21 in the form of coating the silver nano powder or the positive silver nano powder on the fiber yarn.

In this case, when the conductive portion 20 is woven in a runner weave or twill weave, the stability or electrical contact of the tissue arrangement is relatively decreased, and in this embodiment, the conductive portion is woven into the plain weave 21.

Here, the conductive yarn 21 is made of fiber yarns, unlike the copper wire, and has excellent flexibility, the linear heat generating portion 10 and the carbon fiber yarns woven the carbon fiber 12a and the inclined fiber yarn 11a. The conductive portion 20 that woven the 12a and the conductive yarn 21 may be woven through a single weaving facility and process.

That is, when the fiber yarn 11a, which is the warp 11, and the conductive yarns 21 are disposed to be shaped in the warp direction, and the carbon fiber 12a, which is the weft yarn 12, is inserted in the transverse direction therebetween, the conductive portion ( The linear heating element 1 in which the linear heating portion 10 is formed inside the 20 is manufactured through a single weaving process.

By the way, the linear heating element 1 having the linear heating portion 10 woven in the main fabric has the advantage of excellent thermal efficiency and flexibility, but relatively poor stability of the tissue arrangement compared to plain weave.

In consideration of this, in the present embodiment, the linear heating element 1 including the linear heating portion 10 and the conductive portion 20 is coated on the thermoplastic resin liquid 30 to be cured in the thermoplastic resin liquid 30. By this, the arrangement of these tissues is fixed.

As the thermoplastic resin liquid, PE or PP incorporating an illite having a good antibacterial property and gradually dissipating endothermic heat, including the thermoplastic polyurethane liquid employed in the present embodiment, may be adopted.

When the thermoplastic resin solution 30 is coated in this way, the tissue arrangement of the fiber yarn 11a, the carbon fiber yarn 12a, and the conductive yarn 21, which forms the linear heating portion 10, and the conductive portion 20 are formed. In addition to being fixed to be cured, these fiber yarns 11a, carbon fiber 12a, and conductive yarns 21 ensure strong durability and insulation by the thermoplastic resin liquid 30 adhered to the surface. Moreover, lamination | stacking may be carried out with a film according to a use use, and a linear heat generating part and an electrically conductive part may be fixed.

The film is also made of PE or PP incorporating an illite having a function of gradually releasing endothermic heat including a thermoplastic resin solution.

This enables smooth winding and unwinding through improved thermal efficiency and excellent flexibility.

In this embodiment, a mesh fabric having excellent air permeability is disposed between the linear heating elements 1 to have both a beautiful appearance and smooth air permeability.

The conductive yarn 21 forming the conductive portion 20 of the linear heating element 1 has a relatively low conductivity than the copper wire 131a in view of its characteristics, and as shown in FIGS. The conductive mold 131 in which copper wires 131a are embedded is disposed on both sides of the 130, and the conductive parts 20 and the copper wires 131a of the linear heating elements 10 are connected in parallel through the connection lines 132. The conductive mold 131 accommodating the copper wire 131a may be made of a fabric such as lace.

Accordingly, since the copper wire 131a distributes and applies current to each linear heating element 1 in parallel through each connection line 132, each linear heating element 1 disposed on the heating sheet 130 loses resistance. Without a current of the same intensity is applied from the copper wire to achieve a stable heat generation, as a result, the heating sheet 131 of the roll blinder 100 according to the present embodiment ensures the heating state of the same temperature in all areas.
