본 발명은 3층 구조 방진망 및 이의 제조방법에 관한 것으로써, 보다 상세하게는 미세먼지와 초미세먼지, 황사와 같은 외부 오염물질을 차단할 뿐만 아니라 통기성도 우수하며, 항균성 또한 가지는 3층 구조 방진망 및 이의 제조방법에 관한 것이다.The present invention relates to a three-layer structure dustproof net and a method for manufacturing the same, and more particularly, to a three-layer structure dustproof net that not only blocks external contaminants such as fine dust, ultrafine dust, and yellow dust, but also has excellent air permeability and antibacterial properties, and It relates to a manufacturing method thereof.

일반적으로 주택이나 아파트 같은 주거 건물의 창에는 모기, 파리 같은 해충을 차단하고 통기가 가능한 그물망 형태의 방충망이 설치되는 것이 보통이다. 이런 방충망의 소재는 나일론, 폴리에스터 같은 합성 섬유는 물론 알루미늄, 스테인리스 등의 가는 금속망, 최근에는 글라스파이버를 이용한 제품 까지 다양한 소재의 제품들이 개발되어 널리 사용되고 있다. 하지만 최근에는 기존의 방충기능을 가진 방충망을 통해 실내로 유입될 수 있는 유해한 (초)미세먼지의 발생빈도가 잦아지고 이에 따른 미세먼지로 인한 호흡기 계통 질병 발생의 우려가 높아짐에 따라, 기존의 방충망만으로는 안심하고 창문을 열어 환기를 하는 것이 꺼려지고 있는 실정이다. 즉, 실내에서 발생하는 석면, 라돈, 세균, 포름알데히드, 취사, 전자기기 사용 등으로 발생하는 각종 실내 공기오염 물질 문제로 주거생활시 환기가 필수이나, 미세먼지 등 외부 유해물질로 인해 환기가 꺼려지는 실정이다.BACKGROUND ART In general, an insect screen in the form of a net that blocks pests such as mosquitoes and flies and allows ventilation is installed on windows of residential buildings such as houses and apartments. As for the materials of these insect screens, various materials have been developed and widely used, including synthetic fibers such as nylon and polyester, as well as thin metal nets such as aluminum and stainless steel, and recently glass fiber products. However, in recent years, as the frequency of occurrence of harmful (ultra) fine dust that can flow into the room through insect screens with existing insect repellent functions has increased, and as a result, the risk of respiratory system diseases caused by fine dust has increased. It is a situation that is reluctant to open the window and ventilate with peace of mind. In other words, ventilation is essential in residential life due to various indoor air pollutants such as asbestos, radon, bacteria, formaldehyde, cooking, and the use of electronic devices, but ventilation is reluctant due to external harmful substances such as fine dust. is losing.

따라서 기존의 방충망의 기능인 해충차단은 물론이고 유해한 미세먼지까지를 차단해 줄 수 있는 새로운 기능의 방충/방진망의 개발이 절실하게 필요한 상황이다.Therefore, it is urgently needed to develop a new functional insect/dustproof net that can block harmful fine dust as well as pest blocking, which is the function of the existing insect screen.

This invention may be embodied in many different forms and is not limited to the embodiments set forth herein. In order to clearly describe the present invention in the drawings, parts irrelevant to the description are omitted, and the same reference numerals are added to the same or similar components throughout the specification.

도 1을 참조하면, 본 발명의 3층 구조 방진망은 제1원단(10), 나노섬유웹(20) 및 제2원단(30)이 순차적으로 적층된 구조를 가진다.Referring to FIG. 1, the three-layer dustproof net of the present invention has a structure in which a first fabric 10, a nanofiber web 20, and a second fabric 30 are sequentially stacked.

먼저, 제1원단(10)은 도 2에 도시된 것처럼 탄소섬유를 사각형 그물 형태로 제직(weaving)한 것으로서, 15 ~ 35g/m2, 바람직하게는 20 ~ 30 g/m2의 평량을 가질 수 있다. First, the first fabric 10 is obtained by weaving carbon fibers in a rectangular net shape as shown in FIG. 2, and has a basis weight of 15 to 35 g/m 2 , preferably 20 to 30 g/m 2 . can

또한, 제1원단(10)은 평균 개공크기가 150 ~ 250㎛, 바람직하게는 180 ~ 220㎛일 수 있으며, 만일 평균 개공크기가 150㎛ 미만이면 산소투과도가 저하되는 문제가 있을 수 있고, 평균 개공크기가 250㎛을 초과하면 분진포집효율이 저하될 뿐만 아니라, 항균성 또한 저하되는 문제가 있을 수 있다.In addition, the first fabric 10 may have an average pore size of 150 to 250 μm, preferably 180 to 220 μm, and if the average pore size is less than 150 μm, there may be a problem in that the oxygen permeability is lowered, and the average If the pore size exceeds 250 μm, there may be a problem in that not only the dust collection efficiency is lowered, but also the antibacterial property is lowered.

탄소섬유는 PAN(polyacrylonitrile)계 탄소섬유, 레이온(rayon)계 탄소섬유 또는 석유 피치(petroleum pitch)계 탄소섬유일 수 있으며, 바람직하게는 PAN계 탄소섬유일 수 있다. PAN계 탄소섬유는 아크릴로나이트릴(Acrylonitrile)을 중합한 후 방사하여 얻은 PAN(Poly-Acrylonitrile) 섬유를 고온에서 탄화해 제조한 것으로서, 중합, 방사, 소성의 과정을 거쳐서 만들어진 섬유이다. 중합은 아크릴로나이트릴(AN : acrylonitrile)에 열과 압력을 가해 고분자 상태로 만드는 과정이고, 방사는 중합과정을 통해 만들어진 고분자 중합체(PAN : Poly-Acrylonitrile)는 방사 과정을 거쳐 아크릴 섬유로 재탄생하는 과정이며, 소성은 만들어진 아크릴 섬유를 1,200℃ 이상의 고온에서 산화 및 탄화시키는 과정으로, 최종적으로 소성 과정을 거친 아크릴섬유는 탄소(C) 성분만 남아 PAN계 탄소섬유가 제조되는 것이다.The carbon fiber may be a PAN (polyacrylonitrile)-based carbon fiber, a rayon-based carbon fiber, or a petroleum pitch-based carbon fiber, preferably a PAN-based carbon fiber. PAN-based carbon fibers are produced by carbonizing PAN (Poly-Acrylonitrile) fibers obtained by spinning after polymerization of acrylonitrile at a high temperature, and are fibers made through the processes of polymerization, spinning, and firing. Polymerization is the process of applying heat and pressure to acrylonitrile (AN: acrylonitrile) to make it into a polymer state, and spinning is the process by which the high-molecular polymer (PAN: Poly-Acrylonitrile) made through the polymerization process is reborn into acrylic fibers through the spinning process. Firing is a process of oxidizing and carbonizing the acrylic fiber at a high temperature of 1,200 ° C or higher. Finally, only the carbon (C) component of the acrylic fiber that has undergone the firing process remains to produce PAN-based carbon fiber.

또한, 탄소섬유는 단섬유의 섬도가 0.8 ~ 1.2 데니어, 바람직하게는 0.9 ~ 1.1 데니어, 필리멘트수가 2,500 ~ 3,500, 바람직하게는 2,800 ~ 3,200일 수 있으며, 이와 같은 범위를 만족할 때, 우수한 분진포집효율, 산소투과도 및 항균성을 가질 수 있다.In addition, the carbon fiber may have a fineness of 0.8 to 1.2 denier, preferably 0.9 to 1.1 denier, and a filament number of 2,500 to 3,500, preferably 2,800 to 3,200, and when these ranges are satisfied, excellent dust collection efficiency, oxygen permeability and antibacterial properties.

다음으로, 나노섬유웹(20)은 제1원단(10) 일면에 고분자 용액을 전기방사(Electrospinning)하여 형성되는 것으로서, 3 ~ 10 g/m2, 바람직하게는 3 ~ 7 g/m2의 평량을 가질 수 있다. 또한, 나노섬유웹(20) 일면에 코팅층이 형성되어 있을 수 있다. 나노섬유웹(20)은 외부면 및/또는 내부면에 기공을 가지고 있는 섬유의 집합체로서, 코팅층을 형성하는 코팅 조성물은 나노섬유웹(20)의 외부면 뿐만 아니라, 기공을 통해 나노섬유웹(20)의 내부면 일부에 침투하여 일부가 경화되어 코팅층을 형성할 수 있다. 코팅층은 환원된 이산화티타늄을 포함할 수 있다. 환원된 이산화티타늄은 이산화티타늄을 환원시켜 제조된 것으로서 청색(Blue)을 띄는 이산화티타늄일 수 있다. 구체적으로, 환원된 이산화티타늄은 에틸렌디아민 용매에 리튬(Li) 및 이산화티타늄을 넣고, 질소 및 20 ~ 30℃의 온도 조건에서 4 ~ 8일 동안 교반 및 반응시켜 반응물을 제조하고, 제조한 반응물을 염산으로 중화하여 제조된 것일 수 있다. 또한, 코팅층은 나노섬유웹(20) 일면에 0.1 ~ 0.5㎛, 바람직하게는 0.1 ~ 0.3㎛의 두께로 형성되어 있을 수 있다.Next, the nanofiber web 20 is formed by electrospinning a polymer solution on one side of the first fabric 10, and has a concentration of 3 to 10 g/m 2 , preferably 3 to 7 g/m 2 . can have basis weight.
