Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a carbon-

The present invention relates to an apparatus and a method for manufacturing a carbon coated yarn, and more particularly, to a carbon coated yarn manufacturing apparatus and method capable of improving uniformity and productivity by dipping and drying a carbon fiber colloid solution while moving the fiber yarn at high speed. ≪ / RTI >

 Surface heating elements using carbon coated yarns as heating elements are widely used. Since the carbon fiber yarn has a very good far infrared ray emissivity, it can be heated by radiant heat, thereby improving the energy efficiency. Further, the carbon fiber yarn has the advantage of utilizing various useful effects of the far infrared ray.

The carbon-coated cloth is dipped in a small amount of carbon fiber on a plain fiber cloth. After the carbon fiber dipping step, the drying step is performed. The drying process is very important in the process of forming the carbon coating layer coated on the plain fiber yarn. The thickness of the dried carbon coating layer, in which the moisture is evaporated from the carbonized liquid, determines the electrical characteristics, that is, the resistance characteristics, of the carbon coated coating.

Carbon coatings require a carbon solution dipping process and a drying process in the manufacturing process, so the moving speed is controlled to about 1 m to 5 m per minute. Therefore, as disclosed in Korean Patent No. 10-0725189 and Korean Utility Model No. 20-0457918, in order to increase the production amount, a dipping process and a drying process are performed while moving several tens of carbon coated yarns in parallel. The ordinary fiber yarn in the state in which the liquid carbon is adsorbed is not uniform in the adsorption state and the amount contained therein is not accurate and therefore the heat generating characteristic is not uniform and the resistance value becomes variable so that it is not suitable for use as a heating element. Therefore, it is most important to keep the content accurately and to control the adsorption to be uniform.

In the dipping process, a nozzle is used to control the carbon coating thickness of the carbon coated yarn. In order to precisely control the coating thickness, the dipping process may be performed about 2 to 3 times depending on the method as disclosed in Japanese Patent No. 10-1171641. Therefore, when several tens of strands are produced in parallel, the number of nozzles is required by the product of the number of parallel shots and the number of dependent dipping processes.

Careful nozzle management is required to maintain a uniform resistance value of the carbon fiber yarn. As the number of nozzles increases, the number of nozzles to be managed increases accordingly, which increases the burden of nozzle management. Since the carbonaceous solution adheres to the surface of the nozzle, cleaning work is periodically required to remove the carbonaceous solution. For example, if the production process consists of 20 parallel shots and 3 dipping processes, 60 nozzles must be cleaned separately. The cleaning work requires a lot of time and effort since the nozzles must be cleaned one by one with iron brushes.

Also, when dipping and drying about 20 yarns at a time in parallel, the yarn occurrence probability increases. If any yarn is missing, the production process should be stopped and the rejected line must be recovered and recovered. The reason is analyzed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a schematic view of an apparatus for producing carbon coated yarn according to the present invention.

1, an apparatus 100 for manufacturing a carbon coated yarn according to the present invention comprises a supply unit 110, a first impregnation tank 120, a second impregnation tank 130, a first trimming unit 140, A trimming unit 150, a vertical drying furnace 160, a multistage stacking type horizontal drying furnace 170, a winding bobbin 180, and a motor 190.

The supply unit 110 uncovers a plurality of yarns twisted together and folds the plain fiber yarn 10 from the wound supply bobbin and supplies the same to the impregnation tank 120 through a tension adjusting device such as a guide roller 112 with a predetermined tension. Here, the ordinary fiber yarn 10 is fed at the winding speed of the second carbon-coated yarn 30 wound on the winding bobbin 180 rotated by the motor 190. The general fiber yarn 10 can be used without limitation as a fiber yarn capable of maintaining the high strength of the carbon-coated yarn, and examples thereof include natural fiber yarns such as cotton and hemp, synthetic fiber yarns such as nylon, polyester and polypropylene, rayon, Or a mineral fiber yarn such as a semi-synthetic fiber yarn, a glass fiber or a Vasartite fiber. Particularly, it is preferable to use a synthetic fiber such as aramid fiber yarn having heat resistance and flame retardancy and good tensile strength.

Each of the first impregnation tank 120 and the second impregnation tank 130 is composed of a tank containing a carbon colloid solution and a guide roller is installed in the tank to guide the fiber yarn horizontally in the carbon colloidal solution, So that the carbon colloid solution is adsorbed on the surface. A plurality of impellers for dispersing the carbon colloid solution may be installed in the impregnation tanks 120 and 130 and a circulation pipe communicating with the tanks and circulating the carbon solution may be installed on both sides of the impregnation tank 120. A hydraulic motor is further provided at one side of the circulation pipe so that the carbon colloid solution can circulate through the circulation pipe, and an air nozzle for spraying air and an air compressor for supplying air can be installed inside the tank.

The carbon colloid solution or the conductive solution contained in the impregnation baths 120 and 130 may be variously constructed, and carbon having conductivity is essentially required. For the thermal conductivity, the carbon particles are ground to 3 to 200 μm In order to enhance the thermal conductivity, a non-ferrous metal such as gold, silver, copper or nickel is mixed, and the particle diameter of the non-ferrous metal is required to be 3 to 200 μm as well as the carbon particle. The adhesive resin should be mixed at a certain ratio so that the carbon-colloidal solution 122 can be penetrated and absorbed on the surface of the yarn, and silicone resin, polyurethane or the like is used as the adhesive resin. At this time, since the synthetic resin such as silicone polymer or polyurethane exhibits nonconductive property, it is preferable to mix conductive silver nitrate or silver nitrate-containing material in order to conduct electricity. In addition, additives such as ciloid, toluene, MEK, PC2000 and other special properties of the product (elasticity, nano, and flavor) can be added. The mixing ratio of carbon particles, non-ferrous metal particles and adhesive resin is preferably set to 3: 2: 5 in order to satisfy both the adhesiveness and the thermal conductivity, but the mixing ratio may be changed according to the resistance value of the required coating film have. For example, in one embodiment, a mixture of 8-12% carbon, 10-20% graphite, 30-50% urethane based adhesive, 8-16% methanol, 5-10% toluene organic solvent, and 5-10% (MEK) methyl ethyl ketone (MEK) organic solvent.

 The ordinary fiber yarn in which the liquid carbon is adsorbed in the impregnation baths 120 and 130 is not uniform in the adsorption state and the amount contained therein is not accurate and therefore the heat generating characteristic is not uniform and the resistance value is variable.

The inner diameter of the first nozzle of the first trimming part 140 may be 0.7 to 0.9 mm and the inner diameter of the second nozzle of the second trimming part 150 may be 0.8 to 1.2 mm.

FIG. 5 is a flow chart of a preferred embodiment for explaining a method for producing carbon-coated yarn according to the present invention.

In the carbon-coated yarn manufacturing method of the present invention, the normal fiber yarn 10 is fed at the winding speed of the winding bobbin 180 at the feeding portion 110 (S10). In the first impregnation tank 120, the general fiber yarn 10 is dipped into the carbon coating solution at a first predetermined thickness (S12). The first carbon-coated yarn 20 dipped in the first impregnation tank 120 is primarily dried in the vertical drying furnace 160 (S14), and the first dried carbon-coated yarn is dried in the multi- (Step S16). The first carbon-coated yarn 20, which is secondarily dried in the second impregnation tank 130, is dewatered secondarily in the carbon coating solution (S18). The second carbon-coated yarn 30 dipped in the second impregnation tank 130 is firstly dried (S20) in the vertical drying furnace 160 and the first dried carbon-coated yarn 30 is dried in the multi- Followed by secondary drying in the horizontal drying furnace 170 (S22). The second carbon-coated yarn 30 is wound around the winding bobbin 180 at a high winding speed (S24).

As described above, in the present invention, the number of nozzles can be greatly reduced as shown in the following Table 1, by making the nozzle speed high.

In Table 1, in the case of the conventional method, when the diameter is 3 m per minute and the drying time is 4 min, parallel production of 20 nozzles is required in order to produce carbon coated yarn of 240 m per minute. However, in order to maintain the same production rate within the same drying time, parallel production of 6 nozzles is required in the case of 10 m / min, and parallel production of 2 nozzles is required in the case of 30 m / min. In this case, parallel production of 1 nozzle is required.

<Table 1> (Same drying temperature condition)

However, when the number of nozzles is reduced, the length of the drying furnace must be longer than several hundred meters to satisfy the same drying time condition. This is spatially limited. Therefore, if the number of reciprocations in the drying furnace is increased, the drying furnace passing time can be increased while reducing the substantial length of the drying furnace. However, if the number of reciprocations is too large, the tensile force acting on the yarn becomes too high, which may cause embroidery.

Therefore, in the present invention, it is possible to produce a single nozzle system while appropriately adjusting the tension acting on the yarn by maintaining an appropriate number of reciprocations.

The number of reciprocations can be reduced by half by dividing the first dipping into the first and the second, and second, by simultaneously drying the first carbon coated yarn and the second carbon coated yarn in the same drying furnace, the size of the drying furnace is reduced to half, The energy saving effect can be obtained.

In addition, the uniformity of the electrical characteristics of the carbon-coated yarn can be achieved by maintaining the uniform drying state by maximizing the residence time through the horizontal drying furnace.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. Therefore, the scope of the present invention should not be limited by the illustrated embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
