Description

방사능 보호복용 원단 및 이의 제조방법{Fabric for radiation protective clothing and its manufacturing method}Fabric for radiation protective clothing and its manufacturing method}

본 발명은 방사능 보호복용 원단 및 이의 제조방법에 관한 것이다.The present invention relates to a radioactive protective clothing fabric and a method of manufacturing the same.

제1차 세계대전부터 현대사회에 이르기까지 세계 각국의 인류는 화학 작용제, 생물학 작용제 및 방사능의 위험에 노출되어 왔으며, 이를 차단하기 위한 보호용품 소재에 대한 연구는 국방 분야를 비롯하여 화학, 의약, 보건, 위생 등 각종 산업 분야에서 다방면으로 진행되고 있다.From World War I to modern society, humans around the world have been exposed to the dangers of chemical agents, biological agents, and radioactivity, and research on protective material to block these has been conducted in the fields of defense, chemistry, medicine, and health. It is being carried out in various fields such as sanitation, etc.

방사선 방호복은 원자력 발전소의 관리구역을 출입하는 보수요원이나 방사능 물질을 취급하는 실험기술자 등이 착용하는 것으로, 방사선 등과 같은 오염물질로부터 작업자를 보호한다.Radiation protective clothing is worn by maintenance personnel entering the management area of a nuclear power plant or laboratory technicians handling radioactive materials, and protects workers from contaminants such as radiation.

또한, 최근 수년간 전통적 화학작용제 및 비전통적 신종작용제 등을 활용한 테러가 국제사회에 충격을 주고 있으며, 코로나-19의 팬데믹은 생물학적 위협이 군사적 차원을 넘어서 국가적으로 커다란 위협이 될 수 있음을 시사하였다. 이러한 화생방 전장상황 및 테러위협에서 전투원이나 초기대응요원을 보호하는 유일한 수단은 화생방 보호복이다.In addition, in recent years, terrorism using traditional chemical agents and new, non-traditional agents has shocked the international community, and the COVID-19 pandemic suggests that biological threats can go beyond the military and become a major national threat. did. The only means of protecting combatants or first responders in such chemical, biological, and biological battlefield situations and terrorist threats is chemical, biological, and biological protective clothing.

현재, 화생방 보호복은 외피와 내피로 구성되어 있으며, 화생방 보호복 내피로 활성탄 단일 소재가 사용되고 있다. 활성탄 단일 소재의 경우 경제성이 우수한 장점이 있으나, 높은 중량, 제한적인 흡착 성능, 구조적 한계로 인해 무겁고 불편한 소재 특성을 나타내어 복합 기능을 요구하는 미래 화생방 보호의 내피 소재로 발전하기에 어려움이 있다. 또한, 테플론 또는 유기고분자 기반의 선택 투과막으로 구성된 보호복의 경우 에어로졸 입자 방호에 효과적이나, 공기 투과도가 없어 발한에 의한 실질적인 체온 유지가 어려워 제한적으로 사용되고 있다.Currently, chemical, biological and biological protective clothing consists of an outer shell and an inner layer, and a single material, activated carbon, is used as the inner layer of chemical, biological and biological protective clothing. Activated carbon as a single material has the advantage of excellent economic efficiency, but due to its high weight, limited adsorption performance, and structural limitations, it is heavy and uncomfortable, making it difficult to develop into an endothelial material for future chemical, biological and radiological protection that requires complex functions. In addition, protective clothing made of a selectively permeable membrane based on Teflon or organic polymers is effective in protecting against aerosol particles, but its use is limited because it has no air permeability, making it difficult to maintain actual body temperature through sweating.

따라서, 방사능의 위험, 독성 산업물질 또는 미지의 화학물질 위협에 대한 보호 성능이 강화되고 착용감을 향상시킬 수 있는 보호복 기술 개발이 필요하다.Therefore, there is a need to develop protective clothing technology that can enhance protection against radiation hazards, toxic industrial substances, or unknown chemical threats and improve wearing comfort.

상기 탄소섬유 및 폴리에틸렌 섬유를 5:5의 중량비율로 포함하도록 합사하여 복합사를 제조하는 단계; 및manufacturing a composite yarn by plying the carbon fiber and polyethylene fiber in a weight ratio of 5:5; and

상기 복합사를 경사 및 위사로 포함시켜 직물을 제조하는 단계;를 수행하여 제조되는 직물을 적용한다.The fabric manufactured by performing the step of manufacturing a fabric by including the composite yarn as warp and weft yarns is applied.

먼저, 폴리아크릴로나이트릴(PAN) 섬유를 질소분위기에서 1-2℃/분의 승온속도로 300-400℃의 온도까지 승온시킨 후 2-4시간 동안 1차 열처리하여 탄소섬유 전구체를 제조한다. 바람직하게는 1-2℃/분의 승온속도로 330-370℃의 온도까지 승온시킨 후 2.5-3.5시간 동안 1차 열처리한다.First, polyacrylonitrile (PAN) fibers are heated to a temperature of 300-400°C in a nitrogen atmosphere at a temperature increase rate of 1-2°C/min and then subjected to primary heat treatment for 2-4 hours to produce a carbon fiber precursor. . Preferably, the temperature is raised to 330-370°C at a temperature increase rate of 1-2°C/min and then subjected to primary heat treatment for 2.5-3.5 hours.

다음, 상기 탄소섬유 전구체를 질소분위기에서 4-6℃/분의 승온속도로 700-800℃의 온도까지 승온시킨 후 0.5-2시간 동안 2차 열처리하여 탄소섬유를 제조한다. 바람직하게는 5℃/분의 승온속도로 730-770℃의 온도까지 승온시킨 후 0.8-1.2시간 동안 1차 열처리한다.Next, the carbon fiber precursor is heated to a temperature of 700-800°C in a nitrogen atmosphere at a heating rate of 4-6°C/min and then subjected to secondary heat treatment for 0.5-2 hours to produce carbon fiber. Preferably, the temperature is raised to 730-770°C at a temperature increase rate of 5°C/min and then subjected to primary heat treatment for 0.8-1.2 hours.

다음, 상기 탄소섬유를 이용하여 산소플라즈마 처리한다. 상기 산소플라즈마 처리를 통해 탄소섬유 표면에 균일한 작용기를 도입할 수 있다. 이는 후단에서 그래핀 산화물을 용이하게 코팅하기 위한 전처리 공정이다.Next, oxygen plasma treatment is performed using the carbon fiber. Through the oxygen plasma treatment, uniform functional groups can be introduced to the surface of carbon fiber. This is a pretreatment process to easily coat graphene oxide at the later stage.

다음, 카르복시기를 포함하는 그래핀 산화물과 10 중량%의 황산 수용액을 준비하여, 상기 황산 수용액 100 중량부에 대하여 상기 그래핀 산화물을 1 중량부 포함하는 분산액을 제조한 후, 상기 분산액에 산소플라즈마 처리된 탄소섬유를 침지한 후, 40-60℃의 온도에서 6-10시간 동안 반응시켜 산소플라즈마 처리된 탄소섬유를 그래핀 산화물로 코팅한다.Next, prepare graphene oxide containing a carboxyl group and a 10% by weight aqueous solution of sulfuric acid, prepare a dispersion containing 1 part by weight of the graphene oxide based on 100 parts by weight of the aqueous sulfuric acid solution, and then subject the dispersion to oxygen plasma treatment. After immersing the carbon fiber, it is reacted at a temperature of 40-60°C for 6-10 hours to coat the oxygen plasma-treated carbon fiber with graphene oxide.

산소플라즈마 처리된 탄소섬유는 히드록시기 등의 작용기를 포함하고 있기 때문에, 그래핀 산화물에 포함된 카르복시기와 탈수축합반응하기에 용이하다.Since carbon fiber treated with oxygen plasma contains functional groups such as hydroxy groups, it is easy to undergo a dehydration condensation reaction with carboxyl groups contained in graphene oxide.

또한, 상기 그래핀 산화물에 포함된 카르복시기는 산 촉매 존재 하에서 탄소섬유에 포함되어 있는 히드록시기와 반응하여 새로운 공유결합을 형성할 수 있다.Additionally, the carboxylic group contained in the graphene oxide can react with the hydroxyl group contained in the carbon fiber in the presence of an acid catalyst to form a new covalent bond.

탄소섬유의 표면에 그래핀 산화물이 코팅된 후에도, 그래핀 산화물에 포함된 적어도 일부의 카르복시기는 반응에 참여하지 않은 상태로 남아있게 된다. 또한, 대기 조건에서 상술한 작용기들은 산소분자와 반응하여 쉽사리 라디칼화 되며 활성 산소종을 생성한다. 그 결과, 섬유의 표면에서 그램 음성 세균 혹은 그램 양성 세균이 번식하는 것을 지연시키거나 방지할 수 있다.Even after graphene oxide is coated on the surface of the carbon fiber, at least some of the carboxyl groups contained in the graphene oxide remain without participating in the reaction. In addition, under atmospheric conditions, the above-mentioned functional groups react with oxygen molecules and are easily radicalized to generate reactive oxygen species. As a result, it is possible to delay or prevent the propagation of gram-negative or gram-positive bacteria on the surface of the fiber.

이와 같은 반응은 달리 트랜스-에스테리피케이션(trans-esterification) 반응이라 칭해질 수 있으며, 에스테르기 또는 히드록시기가 교환되는 반응에 해당한다. 따라서, 그래핀 산화물의 코팅은 산 촉매 조건에서 섬유의 표면에 위치한 작용기 및 그래핀 산화물의 작용기 사이의 트랜스-에스테리피케이션(trans-esterification) 반응에 의하여 수행된 것이 바람직하다.This reaction may otherwise be called a trans-esterification reaction, and corresponds to a reaction in which an ester group or a hydroxy group is exchanged. Therefore, the coating of graphene oxide is preferably performed by a trans-esterification reaction between the functional groups located on the surface of the fiber and the functional groups of graphene oxide under acid-catalyzed conditions.

전술한 바와 같은 트랜스-에스테리피케이션은 그래핀 산화물 분산액에 섬유를 침지하고 촉매인 산을 첨가함으로써 수행될 수 있다. 이 때, 산이란 루이스 산(Lewis acid)를 의미한다. 루이스 산은 전자를 공여받을 수 있는 종으로서, 황산, 질산, 염산 외에도 금속염을 포함하는 개념이며, 아연 양이온, 이리듐 양이온 등을 포함한다.Trans-esterification as described above can be performed by immersing the fiber in a graphene oxide dispersion and adding an acid as a catalyst. At this time, acid means Lewis acid. Lewis acids are species that can donate electrons, and include metal salts in addition to sulfuric acid, nitric acid, and hydrochloric acid, and include zinc cations and iridium cations.

또한, 상기 트랜스-에스테리피케이션은 40-60℃의 온도조건에서 6-10시간 동안 수행되는 것이 바람직하다. 온도조건이 40℃ 미만이거나 반응시간이 6시간 미만이 경우에는 트랜스-에스테리피케이션이 충분히 진행되지 아니할 가능성이 상당하고, 온도조건이 60℃를 초과하거나 반응시간이 10시간을 초과하는 경우에는 섬유의 훼손이 문제될 수 있다.Additionally, the trans-esterification is preferably performed for 6-10 hours at a temperature of 40-60°C. If the temperature condition is less than 40℃ or the reaction time is less than 6 hours, there is a significant possibility that trans-esterification will not proceed sufficiently, and if the temperature condition is more than 60℃ or the reaction time is more than 10 hours, the fiber Damage may be a problem.

다음, 그래핀 산화물이 코팅된 탄소섬유를 물 및 에탄올을 1:1의 중량비율로 포함하는 세정제를 이용하여 세척한다.Next, the carbon fiber coated with graphene oxide is washed using a detergent containing water and ethanol in a weight ratio of 1:1.

다음, 상기 탄소섬유 및 폴리에틸렌 섬유를 5:5의 중량비율로 포함하도록 합사하여 복합사를 제조한다. 상기 합사는 일반적인 합사 방법을 이용하여 제조한다. 상기 폴리에틸렌 섬유는 바람직하게 난연 섬유이다.Next, a composite yarn is manufactured by plying the carbon fiber and polyethylene fiber in a weight ratio of 5:5.
