Description
본 발명은 내수도, 내한굴곡, 치수변화율, 블로킹성 등이 모두 우수한, 다시말해 복합기능성을 구비함과 동시에 국방규격서 KDC 8305-R0011-1에 명시된 파장별(600~860㎚) 근적외선 영역(600~860㎚)별 반사율을 만족시켜 방수성이 우수한 위장날염 천막덮개 원단에 관한 것이다.The present invention is excellent in water resistance, cold resistance, dimensional change rate, blocking property, etc., that is, having complex functionalities, and at the same time, the wavelength-specific (600-860 nm) near-infrared region (600 to 860 nm) specified in KDC 8305-R0011-1. It relates to a camouflage tent cover fabric excellent in water resistance by satisfying the reflectance by ~ 860nm).
보다 구체적으로, 본 발명은 코팅 처리에 의해서도 기존 위장성능이 유지되어 사람의 시야나 적외선 야간 관측 장비에도 위장효과가 계속 발현되면서도, 내수도, 세탁내구성 등의 기능성이 뛰어나 방수, 단열, 외부습기 차단 등이 가능하여 장병의 생존성 확보와 군장비의 효율적 관리가 가능한 천막덮개 원단에 관한 것이다.More specifically, the present invention maintains the existing gastrointestinal performance even by the coating treatment, while the gastrointestinal effect is continuously expressed in the human visual field or infrared night vision equipment, and has excellent functionality such as water resistance, laundry durability, and the like. The present invention relates to a tent cover fabric capable of securing soldiers' viability and efficiently managing military equipment.
국가방위의 목적으로 작전 수행 중 적에게 노출되어 생명에 위협을 받지 않기 위해서는 기본적으로 주위환경과 구분이 되지 않게하여 생존성을 보장받아야 하기에 날염기술에 적외선 반사율 기술(Infrared ray reflectance technology)을 적용하여 위장성능이 우수한 군용 섬유제품이 개발되고 있다. 특히 숙영 시 장병들의 휴식 및 취침을 통해 전투력을 향상시키기 위한 천막 덮개의 경우 야간 시에 주변환경과 유연하게 대응할 수 있어야 한다. 이를 위해서 종래에 천막덮개로 사용되는 원단은 4도 얼룩무늬를 통해 국내 녹지나 산림지대와 같은 주변 환경 하에서 위장효과(Camouflage effect)를 발휘하여 가시영역에서 주변 환경과 육안 구분이 어렵게 하며 근적외선영역(Near-Infrared)에서는 주위환경과의 반사율 수치와 명암차이를 조절을 통해 야간의 망원경, 적외선 야간관측장비에 의한 탐지 및 관측을 회피할 수 있는 기능성을 부여하였다.Infrared ray reflectance technology is applied to the printing technology because it must be indistinguishable from the surrounding environment in order to be exposed to the enemy during the operation for national defense and not be threatened with life. Therefore, military textile products having excellent camouflage performance have been developed. In particular, the tent cover to improve combat power through resting and sleeping by soldiers during camping should be able to flexibly respond to the surrounding environment at night. To this end, the fabric used as a tent cover conventionally exhibits a camouflage effect under the surrounding environment such as the green area or the forest area through the 4 degree stain pattern, making it difficult to distinguish the surrounding environment from the naked eye in the visible region. Near-Infrared) provides the functionality to avoid the detection and observation by night telescope and infrared night vision equipment by adjusting the reflectance value and contrast difference with surrounding environment.
군용 섬유제품에 대한 위장날염처리에 있어서 미국과 유럽 등의 경우, 적외선 야간 시각장비의 발달로 인해 보다 완벽한 위장효과를 거두기 위해 적외선 파장(민감도) 범위를 1,000~1,500nm까지 적외선 영역대의 상한치를 점차 확대하고 있으며, 최근에는 적외선 야간 시각장비에서도 은폐가 가능한 디지털 위장날염과 투습방수 같은 고기능성이 복합적으로 처리된 섬유제품개발에 집중하고 있으며, 우리군도 섬유제품에 대한 위장효과 증대 및 작전 수행 시에 국가적 위상과 병력들의 생존성 확보를 위해서는 세계적 수준에 손색이 없는 위장용 군관련 섬유제품개발이 필요하다.In the U.S. and Europe, in the gastrointestinal printing treatment of military textile products, the upper limit of the infrared wavelength range is gradually increased from 1,000 to 1500 nm in order to achieve a more perfect gastrointestinal effect due to the development of infrared night vision equipment. Recently, we have been focusing on the development of complex processed textile products such as digital camouflage printing and breathable waterproofing, which can be concealed by infrared night vision equipment. In order to secure the national status and survivability of troops, it is necessary to develop camouflage military-related textile products that are in line with world-class quality.
물론, 국내에서도 4도 얼룩무늬나 디지털 무늬의 위장효과를 극대화하기 위하여 주로 활동하는 지역의 산림지대 등의 환경조건(식물, 바위, 흙)하에서 가시영역과 근적외선영역에서 유사한 색상과 빛의 반사율을 통해 위장용 목적으로 사용되는 섬유제품에 주간 작전 시 시야에 의해 주변 환경과 쉽게 구분되지 않아야 하며 국방규격서(KDC 8305-R0011-1)에서 명시한 600~860nm의 범위에서의 얼룩무늬 전투복으로 사용되는 4색(카키색, 녹색 및 갈색, 흑색)이 각각 요구하는 파장별 요구 반사율 범위에 존재해야만 한다.Of course, in Korea, similar color and light reflectance in the visible and near-infrared areas can be achieved under environmental conditions (plants, rocks, soils) such as forest areas in areas where 4 degrees are used to maximize the camouflage effect of spots and digital patterns. Textile products used for camouflage purposes should not be easily distinguished from the surroundings by visibility during daytime operations, and used as speckled combat clothing in the 600-860 nm range specified in the Defense Standard (KDC 8305-R0011-1). Colors (khaki, green and brown, black) must each be in the required reflectance range for each wavelength required.
하지만, 현재 군에서 사용되는 위장날염된 군용천막덮개의 경우, 기존 위장효과가 후처리 가공(발수, 난연, 코팅 등)에 의해서 가시영역에서의 색상과 근적외선영역(700~860nm)에서의 고유 반사율(Reflectance, %)과 명암 차이가 발생하여 위장효과가 저하되거나 사라지게 되어 결과적으로는 육안이나 적외선 야간 탐색장비에 의해 위치가 노출되게 된다. However, in the case of camouflage printed military tent cover used in the current military, the existing gastrointestinal effect is the color in the visible region and the intrinsic reflectance in the near infrared region (700-860 nm) by post-treatment (water repellent, flame retardant, coating, etc.). (Reflectance,%) and contrast difference occur and the gastrointestinal effect is reduced or disappeared. As a result, the position is exposed by the naked eye or infrared night search equipment.
이에 근래에는 첨단화 되어가고 있는 군 장비의 발전에 발맞추어 위장용 군관련 섬유제품에 대한 군과 장병들의 요구치가 높아지고 있으며, 특히 경계가 소홀히 될 수 있는 야간 숙영 시 천막 위치가 노출되면 주간에 비해 더욱 큰 병력손실을 얻을 수 있으며 이는 전투에서의 패배로도 이어질 수 있기에 이를 예방하기 위한 위장날염 효과의 유지와 적외선 야간 시각장비를 무력화는 물론, 극한의 혹한환경에서도 최신 군장비의 보존과 장병들의 체온 및 쾌적성을 유지할 수 있는 천막덮개 원단에 대한 개발이 요구되고 있다. Recently, in line with the development of advanced military equipment, military and soldiers' demand for camouflage military-related textile products is increasing, especially when the tent location is exposed during night camping, which can be neglected. This can lead to a great loss of troops, which can lead to defeat in combat, so that the gastrointestinal printing effect is prevented and the infrared night vision equipment is disabled, as well as the preservation of the latest military equipment and temperature of soldiers in extreme cold conditions. There is a demand for development of a tent cover fabric that can maintain comfort.
그러므로, 본 발명에서는 기존 위장날염 천막덮개 원단에 코팅 처리 시 발생하던 외관색상과 파장별 반사율 변화를 개선하여 위장성능이 저해되는 문제점을 해결함과 동시에 계절환경에 따른 천막 내부의 기후조건을 유지를 위한 기능성(방한, 방풍, 방수 등) 및 반복 사용에도 내구성이 우수한 군용 천막덮개 원단을 제공하여야 하며 원단의 대상은 섬유소재에 무관하게 적용할 수 있어야 한다.Therefore, the present invention solves the problem that the camouflage performance is impaired by improving the change in appearance color and the reflectance change by wavelength when coating the existing camouflage tent cover fabric, while maintaining the climatic conditions inside the tent according to the seasonal environment. Military tent cover fabric with excellent functionality (cold protection, windproof, waterproof, etc.) and durability against repeated use should be provided and the object of the fabric should be applicable regardless of the textile material.
천막덮개용 원단의 경우 KS K 0590 방법으로 측정한 초기발수도가 5급이고, KS K ISO 6330(B2) 방법으로 5회 세탁후 KS K 0590 방법으로 측정한 발수도가 3급 이상이고, KS K 0591의 저수압법으로 측정한 내수도가 10,000㎜H2O 이상이고, KS M 6893(-20℃에서 40,000회) 방법으로 측정한 내한굴곡성이 5,000㎜H2O 이상이고, KS K ISO 5077 방법으로 측정한 치수변화율은 경사방향 및 위사방향 모두 ±2% 이내이고, KS K 0760 방법으로 측정한 블로킹성이 4급 이상이고, KS K 0700 방법으로 측정한 일광견뢰도, KS K 0430 방법으로 측정한 세탁견뢰도, KS K 0715 방법으로 측정한 땀 견뢰도 및 KS K 0650 방법으로 측정한 마찰견뢰도 모두가 각각 4.5급 이상인 물성들이 요구되고 있다.In case of fabric for tent cover, the initial water repellency measured by KS K 0590 method is 5th grade, and after washing 5 times by KS K ISO 6330 (B2) method, water repellency measured by KS K 0590 method is 3rd grade or higher, KS The water resistance measured by the low water pressure method of K 0591 is 10,000 mmH 2 O or more, the cold resistance bend measured by the KS M 6893 (40,000 times at -20 ° C) method is 5,000 mmH 2 O or more, and KS K ISO 5077 The rate of dimensional change measured by the method is within ± 2% in both the inclined direction and the weft direction.
