Description

탄소섬유 사도정렬 장치 및 이를 이용한 정렬방법{Apparatus and method for arranging a thread guider of carbon fiber}Apparatus and method for arranging a thread guider of carbon fiber}

본 발명은 탄소섬유의 사도정렬 장치 및 이를 이용한 정렬방법에 관한 것이다. 더욱 상세하게, 본 발명은 탄소섬유 생산 공정중에 쉽게 설치가 가능하며, 공간적 제약이 없고 손쉽게 사도정렬이 용이한 탄소섬유의 사도정렬 장치와 이를 이용하여 사꼬임을 방지할 수 있는 사도정렬 방법에 관한 것이다.The present invention relates to an apostolic alignment apparatus for carbon fibers and an alignment method using the same. More specifically, the present invention relates to an apostolic alignment device of carbon fiber which can be easily installed during the carbon fiber production process, has no spatial constraints, and is easily aligned with the apostles, and an apostle alignment method that can prevent twisting using the same. will be.

탄소섬유란 탄소원소의 질량 함유율이 92% 이상으로 이루어진 섬유장의 탄소재료를 일컬으며 실용적으로는 유기물질의 열분해에 의하여 만들어지는 것으로 직경이 약 5㎛ 내지 약 15㎛의 섬유장인 것을 지칭한다. The carbon fiber is a fibrous carbon material having a mass content of carbon atoms of 92% or more, and practically refers to a fiber material having a diameter of about 5 탆 to about 15 탆, which is produced by pyrolysis of an organic material.

폴리아크릴로니트릴(Polyacrylonitrile)계 탄소섬유의 제조방법은 아크릴로니트릴(AN)을 90% 이상 함유하는 단량체를 중합한 공중합체를 방사하고 얻어지는 아크릴계 섬유를 공기 또는 산화성 가스 분위기에서 200℃ 내지 400℃의 온도에서 내염화 처리한 후 300℃ 내지 800℃의 불활성 분위기하에서 100% 내지 120% 인장처리하고 800℃ 내지 2000℃ 불활성 분위기하에서 무장력으로 열처리하여 제조를 하고 있다 (특허출원 제10-1995-002804호 참조). The method for producing polyacrylonitrile-based carbon fibers is obtained by spinning a copolymer obtained by polymerizing a monomer containing 90% or more acrylonitrile (AN), and obtaining the acryl-based fibers in an air or oxidizing gas atmosphere at 200 ° C to 400 ° C. After the flame-resistant treatment at a temperature of 100 ℃ to 100% under an inert atmosphere of 300 ℃ to 800 ℃ and heat treatment under a nominal force under an inert atmosphere of 800 ℃ to 2000 ℃ (Patent No. 10-1995-002804 Reference).

탄소섬유는 기계적 강도 및 탄성율이 높고 내열성이나 내약품성 등의 성질이 우수하여 항공·우주산업 및 토목·건축재료, 자동차, 선박, 전기·전자재료, 스포츠·레저용품 분야 등 고성능 복합재의 보강섬유 소재로서 이용되고 있다(일본공개특허공보 제2008-274117호 참조).Carbon fiber has high mechanical strength and elastic modulus, and has excellent properties such as heat resistance and chemical resistance, so as to reinforce fiber materials of high-performance composite materials such as aviation, aerospace industry, civil engineering, building materials, automobile, ship, electric, electronic materials, sports and leisure goods (See Japanese Laid-Open Patent Publication No. 2008-274117).

탄소섬유 제조공정은 주로 탄소섬유 다발을 동시에 열처리하는 공정으로 이 탄소섬유 다발은 내염화처리 및 열처리공정 중 쉽게 섬유간 사꼬이는 문제가 발생할 수 있다. 이런 문제는 섬유 다발간 마찰에 의한 섬유 손상을 야기시켜 섬유의 응집성(fiber bundle cohesion), 결속성(bundling)을 방해하고, 보풀(fluff) 형성을 초래하여 탄소섬유의 물성저하 및 제품 품질저하를 야기시킨다. The carbon fiber manufacturing process is mainly a process of heat treating carbon fiber bundles at the same time. This carbon fiber bundle can easily cause inter-fiber twisting during the flameproofing and heat treatment process. This problem causes fiber damage due to friction between fiber bundles, impedes fiber bundle cohesion, bundling, and fluff formation, resulting in deterioration of carbon fiber properties and product quality. Let's do it.

이러한 문제를 해결하기 위해서는 각 공정 단계별 탄소섬유 다발의 사도정렬을 실시하여 사꼬임을 방지해야 한다. 사도정렬 방법은 사도정렬용 섬유를 탄소섬유 다발 사이로 직조하여 사도간 꼬임을 확인/제거할 수 있다. 종래에는 고가의 직조 기계를 이용하여 사도정렬을 실시하였으나 장비를 설치할 수 있는 공간적 제약 및 고강도 탄소섬유의 물리적 특성으로 인해 직조기계의 트러블 발생이 빈번하였다.In order to solve this problem, the apostle alignment of the carbon fiber bundles in each process step should be performed to prevent twisting. The apostle alignment method can check / remove the twist between the apostles by weaving the apostle alignment fibers between the carbon fiber bundles. Conventionally, the apostolic alignment was performed by using an expensive weaving machine, but problems occurred in the weaving machine due to the space constraints to install the equipment and the physical characteristics of the high-strength carbon fiber.

이에 본 발명은 탄소섬유 생산 공정중에 쉽게 설치가 가능하며, 공간적 제약이 없고 손쉽게 사도정렬이 용이한 탄소섬유 사도정렬 장치를 이용하여 사꼬임을 방지할 수 있는 탄소섬유의 사도정렬 방법을 제공하는데 그 목적이 있다. Accordingly, the present invention provides a method for aligning apostles of carbon fibers, which can be easily installed during a carbon fiber production process and prevents twisting by using a carbon fiber apostle alignment device, which has no space constraint and easily aligns apostles. There is a purpose.

If it is characterized in that the apostle alignment fibers are introduced in a direction perpendicular to the progress direction of the carbon fiber.
