<섬유원단에 대한 실시예><Example about the fiber fabric>

본 발명에 의한 섬유원단은 각각 370mesh 입자크기의 탄소 95g, 세라믹 5g이 혼합된 혼합물과, 용제로 사용되는 톨루엔(toluene: 메틸벤젠)이 혼합되어 겔(gel) 상태로 표면에 코팅되어 제조된다.The fiber fabric according to the present invention is prepared by mixing a mixture of 95 g of carbon and 5 g of ceramic having a particle size of 370 mesh, and toluene (methylbenzene) used as a solvent, and coating the surface with a gel.

상기 섬유원단은 탄소와 세라믹을 각각 370mesh의 입자크기로 볼밀 등의 분쇄기에서 분쇄하고, 분쇄된 탄소 95g과 세라믹 5g을 혼합기에서 혼합한 후, 이 혼합물을 톨루엔 등의 적정용제와 섞어 교반기에서 교반하고 겔 상태로 유지시켜, 이 결과물을 옷이나 침구 등으로 제작될 섬유원단에 코팅기로 코팅한 다음 건조과정을 수행하여 얻었다.The fiber fabric is pulverized carbon and ceramic in a particle mill of 370 mesh, respectively, and mixed the pulverized carbon 95g and ceramic 5g in a mixer, and then mixed the mixture with a suitable solvent such as toluene and stirred in a stirrer The resultant was maintained in a gel state, and the resultant was coated with a coater on a fabric fabric to be fabricated with clothes or bedding, followed by drying.

상기된 실시예와 같은 실험을 분쇄된 입자크기 및 함량을 변화시켜 여러번 반복실시한 결과, 탄소와 세라믹은 각각 350 ~ 400mesh의 입자크기를 갖는 것이 가장 바람직하며, 이들의 혼합비율은 93 ~ 97중량%와 7 ~ 3중량%로 혼합되는 것이 이상적임을 알 수 있었다.As a result of repeatedly performing the same experiment as the above-described examples by changing the pulverized particle size and content, it is most preferable that the carbon and the ceramic have a particle size of 350 to 400 mesh, respectively, and the mixing ratio thereof is 93 to 97% by weight. And 7 to 3% by weight was found to be ideal.

여기서, 이들의 입자크기가 350mesh 크기 미만을 경우에는 섬유표면이 매우 거칠어지게 되어 재질감이 떨어지며, 400mesh를 초과할 경우에는 재질감이 매우 우수해지기는 하지만 제조경비가 높아지게 된다.Here, when their particle size is less than 350 mesh size, the surface of the fiber becomes very rough and the texture is degraded. When the particle size exceeds 400 mesh, the texture is very excellent, but the manufacturing cost is increased.

또한, 상기 탄소와 세라믹의 함량을 비교하여 설정된 함량에 비해 세라믹의 함량이 초과될 경우에는 탄소의 통전성이 과도하게 낮아지며, 탄소의 함량이 초과될 경우에는 원적외선의 방사효율 및 두 혼합물간의 결합력이 현저히 낮아지게 된다.In addition, when the content of the ceramic is greater than the content set by comparing the content of the carbon and the ceramic, the conductivity of the carbon is excessively low, and when the content of the carbon is exceeded, the radiation efficiency of far infrared rays and the bonding force between the two mixtures are remarkably reduced. Will be lowered.

상기된 것과 같은 섬유원단이 옷이나 침구 등의 제품에 적용되었을 때, 탄소와 세라믹의 혼합물이 코팅된 이들 제품에서는 원적외선이 대단히 높은 효율로 신체에 방사된다.When such fabrics as described above are applied to products such as clothes or bedding, in these products coated with a mixture of carbon and ceramic, far infrared rays are radiated to the body with very high efficiency.

이는 상기 원적외선이 주지된 것과 같이 생물의 분자를 활성화시키며, 탄소와 세라믹은 이러한 원적외선의 방사효율이 자체적으로 높다는 사실에 기인하여 제품을 사용하는 사용자의 신진대사를 활성화시키게 됨은 자명하다.It is apparent that the above-mentioned far infrared rays activate the molecules of living things, and carbon and ceramics activate the metabolism of the user who uses the product due to the fact that the radiation efficiency of such far infrared rays is high on its own.

특히, 상기 섬유원단으로 옷을 제작하여 착용하였을 때, 상기 옷은 정전기에 대비한 접지부재의 역할을 하게 되는데, 이는 원단 코팅물의 함유물 중 도전체인 탄소에 의해 정전기가 옷으로 통전되어 소멸되기 때문에 가능한 작용이다.In particular, when the fabric is made of the fabric fabric and worn, the clothing serves as a grounding member against the static electricity, since the static electricity is passed through the clothes by the carbon, which is a conductor in the coating material of the fabric coating is extinguished. Possible action.

<성형물에 대한 실시예><Example about the molding>

본 발명에 의한 성형물은 각각 350mesh 입자크기의 탄소 97g, 세라믹 3g이 혼합된 혼합물 73g과, 합성수지 고형분 27g이 혼합되고 성형되어 제조된다.The molding according to the present invention is produced by mixing and molding 73 g of a mixture of 350 g of carbon particles and 3 g of ceramic, and 27 g of a synthetic resin solid.

상기 성형물은 탄소와 세라믹을 각각 350mesh의 입자크기로 볼밀 등의 분쇄기에서 분쇄하고, 분쇄된 탄소 97g과 세라믹 3g을 혼합기에서 혼합한 후, 이 혼합물과 합성수지 고형분을 각각 73g과 27g의 함량으로 성형기에서 혼합하고 성형시키는 과정을 수행하여 얻었다.The molding is pulverized carbon and ceramic in a ball mill or the like with a particle size of 350 mesh, respectively, and mixed the pulverized carbon 97g and ceramic 3g in a mixer, and then the mixture and the synthetic resin solid content of 73g and 27g respectively in the molding machine Obtained by performing the mixing and molding process.

상기 성형물은 컴퓨터의 외장 케이스, 모니터의 케이스 등과 같은 컴퓨터 용품으로 선택되기도 하고, 일반 가정에서 사용되는 선반이나 의자 등과 같은 제품이기도 하며, 건축용 벽판 등의 내장재와 같은 여러 합성수지 제품일 수도 있게 된다.The molded article may be selected as a computer article such as an external case of a computer, a case of a monitor, a product such as a shelf or a chair used in a general home, or may be various synthetic resin products such as interior materials such as building wall boards.

상기된 실시예와 같은 실험을 혼합물과 합성수지 고형분의 함량을 변화시키며 반복실시한 결과, 혼합물과 합성수지 고형분은 70 ~ 75중량%와 25 ~ 30중량%의 비율로 혼합되는 것이 가장 이상적임을 알 수 있었다.As a result of repeating the same experiments as the above-described experiments with varying contents of the mixture and the resin solids, it was found that the mixture and the resin solids were ideally mixed at a ratio of 70 to 75% by weight and 25 to 30% by weight.

여기서, 상기 혼합물이 설정된 범위를 초과하여 혼합된 경우에는 각 조성물 간의 결합력이 현저히 떨어져 제작된 제품이 쉽게 파손되며, 상기 혼합물에 비해 합성수지 고형분이 설정된 범위를 초과하여 혼합된 경우에는 원적외선의 방사효율이 현저히 낮아지게 된다.Here, when the mixture is mixed beyond the set range, the bonding strength between the compositions is significantly lowered, and the manufactured product is easily broken. When the solid content of the resin is mixed over the set range, the radiation efficiency of far infrared rays is increased. It will be significantly lower.

상기와 같은 본 발명에 의한 성형물은 전술된 원적외선의 기능에 근거하여,사용자와 근거리에서 사용되는 컴퓨터 용품, 일반 가정용품에 적용되었을 때 높은 효율의 원적외선 방사로 인해 인체에 이로움이 제공된다.The molding according to the present invention as described above is beneficial to the human body due to the high efficiency of far-infrared radiation when applied to the user, computer products used in the near field, general household goods based on the function of the far infrared.

뿐만아니라, 상기 컴퓨터 용품과 같이 전자파가 대량 노출되는 제품에서는 도전체인 탄소에 의해 전자파가 제품 자체에서 통전되고 소멸되어 제품 사용자의 건강에 이로움을 제공한다.In addition, in a product to which a large amount of electromagnetic waves are exposed, such as computer products, electromagnetic waves are energized and dissipated in the product itself by carbon, which is a conductor, thereby providing health benefits for the user of the product.

그리고, 상기 혼합물이 건축내장재 또는 실내의 벽지등에 사용되면, 이들은 상기된 원적외선의 기능에 의해 거주자 건강에 이로움을 제공하며, 집안에 곰팡이 등의 발생을 억제시켜 보다 쾌적한 주거공간이 되도록 한다.And, if the mixture is used for building interior materials or indoor wallpaper, they provide benefits to the residents' health by the function of the far-infrared rays described above, and to suppress the occurrence of mold and the like in the house to make a more comfortable living space.
