Abstract
본 발명은 통기성 필름이나 투습방수 필름을 포함하지 않는 대신, 나노섬유가 부직포 또는 직물 또는 편물과 복합화된 보호복용 합지 원단을 무봉제 공정을 적용하여 제조한 통기쾌적성과 바이러스 차단성을 동시에 보유하는 보호복 및 이의 제조방법을 제공한다.The present invention does not include a breathable film or a moisture-permeable waterproof film, but instead of a protective clothing that has breathability comfort and virus blocking properties at the same time, manufactured by applying a non-sewn process to a laminated fabric for protective clothing in which nanofibers are combined with nonwoven fabrics, woven fabrics, or knitted fabrics. It provides a suit and a manufacturing method thereof.
Description
본 발명은 기존의 보호복 원단에 적용되었던 통기성 필름이나 투습방수 필름, 투습 접착제 등을 사용하지 않는 대신 나노섬유를 사용하여 이를 부직포, 직물, 또는 편물 등과 복합화한 합지 원단, 그리고 이를 무봉제 공정을 통하여 제조한 통기쾌적성과 높은 바이러스 및 화학물질 차단성을 동시에 보유하는 보호복 및 이의 제조방법에 관한 것이다. 본 발명을 통하여 제조한 보호복은 유럽의 보호복 차단성 평가 규격 EN 14126 기준 인공혈액, 박테리오파지에 대한 저항성 CLASS 3 이상 및 EN 14605 기준 화학물질투과 저항성 CLASS 1 이상의 고 차단성과 더불어, 착용자의 쾌적성 확보를 위한 KS K 0570 기준 4.0 mm/s 이상의 공기투과도 및 KS K 0594 기준 10,000 g/m2·24h 이상의 투습도를 보유한다.The present invention uses nanofibers instead of using breathable films, moisture-permeable and waterproof films, and moisture-permeable adhesives, which have been applied to existing protective clothing fabrics, and combines them with non-woven fabrics, fabrics, or knitted fabrics, and a non-sewing process. It relates to a protective clothing that simultaneously possesses ventilation comfort and high virus and chemical barrier properties manufactured through The protective clothing manufactured through the present invention meets the European protective clothing barrier evaluation standard EN 14126 resistance to artificial blood and bacteriophage CLASS 3 or higher and EN 14605 standard chemical permeation resistance CLASS 1 or higher, as well as high barrier properties, wearer's comfort It has an air permeability of 4.0 mm/s or more based on KS K 0570 and a moisture permeability of 10,000 g/m 2 ·24h or more based on KS K 0594.
보호복은 작업자의 안전을 확보할 수 있는 필수용품 중 하나이며, 바이러스 및 혈액, 화학물질 등의 차단 성능과 투습/통기 성능이 겸비되어야 안전성과 쾌적성을 모두 확보할 수 있다.Protective clothing is one of the essential items that can ensure the safety of workers, and both safety and comfort can be secured only when the performance of blocking viruses, blood, chemicals, etc., and the performance of permeability/ventilation are combined.
특히 COVID-19 대유행에 따라 국내에서도 보호복의 바이러스 차단성능에 대한 수준 향상 요구가 커지고 있으며, 최근에는 사용자의 안전성과 보호기능을 강화하기 위하여 바이러스 및 혈액 침투 차단성의 경우 최고 수준인 CLASS 6를 요구하고 있어, 향후 개발되는 의료용 보호복 제품은 최고 수준의 차단성을 기본적으로 보유해야 할 것으로 판단된다.In particular, with the COVID-19 pandemic, there is a growing demand for improvement in the virus blocking performance of protective clothing in Korea. Therefore, it is judged that medical protective clothing products developed in the future should basically have the highest level of barrier properties.
그러나 현재까지 국내에서는 여전히 바이러스 차단 성능이 확보되지 않은 보호복이 제조 및 공급되고 있으며, 국내외에서 개발된 통기성 필름이나 투습방수 필름 등을 부직포와 합지시켜 제조하는 바이러스 차단 보호복은 차단성은 높으나 통기성이 없고 쾌적성이 현저히 결여되어 사용자의 불만이 높으며 특히 의료 현장에서의 안전성과 편의성을 심각하게 위협하고 있다.However, until now, protective clothing that does not have virus blocking performance is still being manufactured and supplied in Korea, and virus blocking protective clothing manufactured by laminating a breathable film or a moisture-permeable waterproof film developed domestically and abroad with non-woven fabric has high barrier properties but poor breathability. There is no comfort, and the user's dissatisfaction is high, especially in the medical field, and the safety and convenience are seriously threatened.
나노기술은 nanoscale의 소재를 사용함으로써 원자나 분자 수준에 근접한 조작을 가능하게 하며, 특히 바이러스는 백~수백 나노미터 정도의 작은 크기를 가지므로, 항바이러스 소재의 개발은 나노기술에 근거해야 한다.Nanotechnology enables manipulation close to the atomic or molecular level by using nanoscale materials. In particular, viruses have a small size of about hundreds to hundreds of nanometers, so the development of antiviral materials must be based on nanotechnology.
전기방사로 제조된 나노섬유는 마이크로 단위의 섬유보다 비표면적이 매우 크며, 작은 기공을 가지고 있을 뿐 아니라 기공의 크기를 자유롭게 조절할 수 있고, 강한 표면 흡착성, 물질에 대한 선택적 투과성을 보유하면서도 서로 다른 소재의 복합화가 가능하다는 많은 장점을 가진다. 특히 나노구조에 기인하여 높은 바이러스 차단성과 내수압을 보유하면서도 섬유구조체 특유의 통기성과 투습성을 보유하고 있어 차단성과 쾌적성을 겸비한 차세대 보호복 소재로서 적용 가능하다.Nanofibers produced by electrospinning have a much larger specific surface area than micro-scale fibers, have small pores, can freely control the size of pores, have strong surface adsorption, and selective permeability to materials while maintaining different materials. It has many advantages that can be combined. In particular, it can be applied as a next-generation protective clothing material that combines barrier properties and comfort, as it has high virus barrier properties and water resistance due to its nanostructure, as well as air permeability and moisture permeability unique to its fiber structure.
더불어 수작업으로 봉제된 후 심실링 테이프를 부착하여 마감처리하는 기존 보호복 제조방법을 개선하여, 초음파융착 기법을 적용하여 무봉제율이 높은 보호복을 제조하면 보호복의 차단성을 더욱 극대화 할 수 있다.In addition, by improving the existing protective clothing manufacturing method, which is sewn by hand and then finished by attaching seam sealing tape, by applying ultrasonic welding technique to manufacture protective clothing with a high sewing-free rate, the barrier properties of protective clothing can be further maximized. there is.
선별진료소 등 열악한 환경에서 근무하는 의료진의 경우 통풍이 안되는 보호복 착용으로 상상을 초월하는 고통과 어려움을 호소하고 있다. In the case of medical staff working in harsh environments such as screening clinics, they are complaining of pain and difficulties beyond imagination due to wearing protective clothing with poor ventilation.
일반적으로 바이러스 및 화학물질 차단성을 보유한 보호복은 부직포와 통기성 필름을 접착제로 합지한 원단을 사용하는데 통기성 필름의 경우 바이러스 차단성이 매우 낮아 합지 공정에서 접착제를 전면 도포하여 차단성을 높이는 방법이 적용되어 왔으나, 이 경우 통기성과 투습도가 현저하게 저하되어 사용자의 쾌적성이 떨어진다. 또한 현재 고성능 보호복 원단에 적용되는 투습방수필름은 기공의 크기가 작아 바이러스 및 혈액 침투를 차단하는 측면에서는 유리하지만, 필름과 접착제의 사용으로 통기성이 매우 낮거나 아예 없고 투습도의 향상도 제한적이다.In general, protective clothing with virus and chemical barrier properties uses a fabric in which a nonwoven fabric and a breathable film are laminated with an adhesive, but in the case of a breathable film, the virus barrier property is very low, so it is difficult to increase the barrier property by applying adhesive all over during the laminating process. However, in this case, air permeability and moisture permeability are remarkably reduced, resulting in poor user comfort. In addition, the moisture-permeable waterproof film currently applied to high-performance protective clothing fabric has a small pore size and is advantageous in terms of blocking virus and blood penetration.
보호복의 제조 과정을 살펴보면, 효율적인 보호복 제조를 위해서 여러 개의 조각을 합쳐서 하나의 보호복을 제작하게 되며, 구체적으로 나뉘어진 조각을 재봉하여 보호복을 제조한다. 대부분의 의류는 재봉하여 제작하더라도 문제가 될 것이 없지만, 보호복의 경우는 재봉을 하는 경우 바늘이나 실이 원단을 통과하여 미세한 틈새가 생긴다면 이러한 틈으로 바이러스나 혈액, 화학물질 등이 침투될 수 있기 때문에, 사람의 신체를 보호한다는 목적을 달성하기 어려울 수 있다. Looking at the manufacturing process of protective clothing, a protective clothing is manufactured by combining several pieces for efficient manufacturing of protective clothing, and the protective clothing is manufactured by sewing the specifically divided pieces. There is no problem even if most clothing is sewn, but in the case of protective clothing, if a needle or thread passes through the fabric and creates a fine gap, viruses, blood, or chemicals can penetrate through these gaps. Because of this, it may be difficult to achieve the purpose of protecting the human body.
따라서 차단성과 쾌적성을 동시에 보유하는 보호복을 제조하기 위해서는 통기성 필름이나 투습방수 필름을 대체할 수 있는 새로운 소재와 봉제 기술의 적용이 필요하다.Therefore, in order to manufacture protective clothing that has both barrier properties and comfort, it is necessary to apply new materials and sewing techniques that can replace breathable films or moisture-permeable and waterproof films.
본 발명에서는 기존의 보호복에서 사용되어 왔던 통기성 필름이나 투습방수 필름, 투습 접착제 등을 사용하지 않는 대신, 나노섬유와 부직포, 직물, 편물 등을 합지한 복합소재 원단을 무봉제 공정을 적용하여, 뛰어난 바이러스 및 화학물질 차단성과 기존의 보호복 원단에서는 구현이 불가능한 통기쾌적성을 동시에 보유하는 보호복을 제조하는 방법을 제공한다.In the present invention, instead of using breathable films, moisture-permeable waterproof films, moisture-permeable adhesives, etc., which have been used in existing protective clothing, a composite material fabric combining nanofibers, nonwoven fabrics, fabrics, knitted fabrics, etc. is applied to the sewing process, Provides a method for manufacturing protective clothing that simultaneously possesses excellent virus and chemical barrier properties and breathability comfort that cannot be realized with existing protective clothing fabrics.
