이밖에도 정전기방지나 전자파차폐를 위한 여러 가지 재질들이 사용되고 있는데 아직까지는 도전성카본이 주로 사용되고 있으며 페라이트분말을 혼합하여 사용하기도 한다.In addition, various materials are used for the prevention of static electricity and electromagnetic shielding, but conductive carbon is mainly used and mixed with ferrite powder.

그러나 이들은 기본적으로 도전성카본과 같은 도전성물질의 함량이 많이 들어가야만 요구되는 특성을 만족할 수 있는데, 섬유제품의 품질면에서 보면 도전성카본 등의 함량이 많아지면 많아질수록 섬유의 물성이 낮아지고 섬유의 생산성도 낮아지기 때문에 무작정 많이 넣어 줄 수가 없다. 따라서 도전성이 우수한 합성섬유를 만드는 것은 매우 어려운 일이었다. 더구나, 굵기가 굵은 섬유원사에는 도전성물질의 함량을 어느 정도 높게 첨가할 수 있으나 일반적으로 많이 사용되고 있는 의류용 섬유와 같이 가느다란 섬유에는 매우 적은 양밖에는 첨가할 수 없었기 때문에 도전성이 우수하고 섬유물성도 우수한 섬유원사를 생산하기가 어려웠다.However, they can basically satisfy the required characteristics only when the content of the conductive material such as conductive carbon is high. In terms of the quality of the textile product, the more the content of the conductive carbon, the lower the physical properties of the fiber and Productivity is also low, so I can not put a lot. Therefore, it was very difficult to make a synthetic fiber excellent in conductivity. In addition, a thicker fiber yarn may have a higher content of conductive material, but only a very small amount can be added to thin fibers such as clothing fibers, which are generally used. It was difficult to produce good fiber yarns.

본 발명에서는 상기와 같은 문제점을 해소하고 우수한 도전성 및 열전도특성 을 갖는 섬유원사들 제조할 수 있는 방법을 제시하고자 하였으며 구체적으로는 [도 1]과 같은 구조를 갖고 있고 판상이어서 도전성 및 열전도특성이 타 물질에 비해 월등히 우수한 흑연을 사용하여 도전성 및 열전도특성이 우수한 기능성섬유를 제조하고자하였다. 흑연의 사용량을 기존의 도전성물질에 비하여 소량만 사용하여도, 흑연은 특유의 우수한 도전성 및 열전도특성을 갖기 때문에, 섬유원사의 방사공정에서도 막힘이나 사절 등과 같은 문제점이 발생하지 않을 뿐 아니라 방적 및 제직 등의 후 공정에서도 장치마모나 물성저하 등의 문제를 거의 일으키지 않아 상업적 대량생산을 하는데 문제가 없도록 하고자하였다.In the present invention, to solve the problems described above and to propose a method for producing fiber yarns having excellent conductivity and thermal conductivity properties, and specifically have a structure as shown in FIG. It was intended to produce functional fibers having excellent conductivity and thermal conductivity using graphite which is superior to materials. Even if the amount of graphite used is small, compared to the existing conductive materials, graphite has unique conductivity and thermal conductivity characteristics, so that the spinning process does not cause problems such as clogging or trimming, but also spinning and weaving. Even after the process, such as abrasion and physical property degradation rarely cause problems in the commercial mass production was intended to be no problem.

이와 함께 흑연은 [도2]에서도 알 수 있는 바와 같이 얇은 판상의 형태로 겹쳐져 있는 형상으로서, 이것을 그대로 섬유제조공정에 투입할 경우에는 비록 적은 양을 첨가할지라도 엉키어 있는 응집상태가 절대로 풀어지지 않기 때문에 필터 등이 막혀서 작업이 중단되거나, 섬유의 사절이 많이 발생하는 등, 정상적인 섬유방사작업을 할 수 없게된다. 이 같은 문제는 섬유방사공정과 같은 대단위 장치공정에 있어서는 치명적인 것으로 섬유방사자체를 불가능하게 할 수 있는 것이다.In addition, as shown in FIG. 2, graphite is stacked in the form of a thin plate, and when it is put into the fiber manufacturing process as it is, the tangled state of coagulation is never released even if a small amount is added. This prevents normal fiber spinning operations, such as clogging of the filter or interruption of work, or a large number of fiber breaks. Such a problem is fatal in a large unit process such as a fiber spinning process, which can make the fiber spinning itself impossible.

본 발명에서 사용한 흑연은 속이 비대있는 얇은 판이 겹쳐져 있는 형상으로 이루어져 있다. 이 판들은 다른 물질에 비해서는 서로 강하게 결합된 것은 아니나, 수지와 혼합되어 용융 및 방사공정을 거치면서 물리적 힘만으로 판들이 분리될 정도로 약한 결합은 아니다. 따라서 흑연을 수지와 함께 용융 및 방사하여 섬유를 만들기 위하여서는 흑연을 미리 분쇄하여 섬유생산 공정에 문제를 일으키지 않도록 해야한다.The graphite used in the present invention has a shape in which a thin plate with an enlarged inside is overlapped. These plates are not strongly bonded to one another compared to other materials, but they are not weak enough to separate the plates by physical force alone while being mixed with the resin and undergoing melting and spinning. Therefore, in order to melt and spin the graphite together with the resin to make the fiber, the graphite must be crushed in advance so as not to cause problems in the fiber production process.

본 발명에서는 흑연을 분쇄 및 분산시키기 위해 비드를 사용하는 밀(아트리션밀, 다이노밀, 볼밀 등등)을 이용하였으며 분산매와 분쇄매체의 종류와 크기를 다양하게 사용하여 원하는 크기로 조절하여 사용할 수 있다.In the present invention, a mill (atrium mill, dynomill, ball mill, etc.) using beads is used to pulverize and disperse graphite, and various types and sizes of the dispersion medium and the pulverizing medium may be used to adjust the desired size. .

섬유원사제조공정을 선택할 경우에도 고려할 사항들이 있는데, 폴리에스테르 섬유를 예로 들면 흑연을 마스터배치상태로 투입하여 섬유원사를 제조하는 것에 비하여 에틸렌글리콜 중에서 분쇄 및 분산시켜 직접 폴리에스테르 중합공정에 투입하는 것이 최종적으로 흑연이 섬유내부에서 잘 분산되어 있게 된다.There are also considerations when choosing a fiber yarn manufacturing process. For example, polyester fiber is crushed and dispersed in ethylene glycol and directly added to the polyester polymerization process as compared with the production of fiber yarn by adding graphite in a masterbatch state. Finally, graphite is well dispersed within the fiber.

마스터배치상태로 투입하는 경우에는 마스터배치를 제조할 때, 흑연의 분산이 잘되도록 하여야한다. 즉 흑연과 폴리에스테르의 혼합이 잘되도록 폴리에스테르 수지는 칩상태로 사용하는 것보다 파우더 형태의 것을 사용하는 것이 좋으며 혼합시간을 충분히 하는 것이 바람직하다.In the case of the master batch, the master batch should be prepared so that the graphite is well dispersed. That is, it is preferable to use a powder form of the polyester resin so as to mix the graphite and polyester well, and to sufficiently mix the time.

이하 실시예를 통하여 본 발명에 대하여 상세히 설명한다. 그러나 본 발명은 실시예의 범주에만 국한되는 것이 아님을 알려두고자 하며, 예를 들어 폴리에스테르 섬유를 중심으로 설명하였지만 폴리에스테르 섬유뿐 아니고 섬유로 생산이 가능한 나일론, 아크릴, 폴리프로필렌, 폴리우레탄 및 그 밖의 일반적으로 섬유로서 만들 수 있는 모든 수지에도 적용될 수 있는 것이다.Hereinafter, the present invention will be described in detail with reference to the following examples. However, the present invention is not intended to be limited to the scope of the embodiments, for example, the polyester fiber as described above, for example, but can be produced not only polyester fiber, but also nylon, acrylic, polypropylene, polyurethane and its It can also be applied to all resins that can be generally made as fibers.
