The present invention relates to an ultrafine dust-screening screening net and a method of manufacturing the same, which is fabricated in the form of a screen for insect protection and dustproofing for general windows, (Fabric 1), an ultrafine dust-proofing net having a pore size of 0.1 to 100 μm was formed on the fabric 1 (nylon 2) in order to shield ultrafine dust by spun nylon resin in the form of nanofiber, A nano-dust-proofing layer capable of blocking ultrafine dust produced by hot melt resin so that the nano dust-proof layer can be firmly fixed to the polyester fabric mesh by passing another fabric 1 over the nano-radiation surface of the fabric 2, .

본 발명에 의해 제작된 나노방진망은 창틀이나 문틀 등에 부착되어 있는 종래의 방충망을 대체하여 창틀에 끼우는 방식으로 사용할 수 있고, 또는 기존의 방충망 위에 덧붙여서 미세먼지 차단의 기능을 갖게 할 수 도 있는 등 현재 기관지나 호흡기 계통의 질환을 유발시키는 주범으로 인식되고 있는 초미세먼지의 실내 유입을 최대한 차단시켜줄 수 있는 초미세먼지 차단용 나노방진망을 제공한다.The nano-dazzling network manufactured by the present invention can be used in a manner that it is sandwiched by a window frame instead of a conventional screen inspecting net attached to a window frame or a door frame, or may have a function of blocking fine dust in addition to the existing screen inspecting net. The present invention provides a nanodisperse network for blocking ultrafine dust that can block the inflow of ultrafine dust, which is perceived as a main cause of diseases of the engine and respiratory system, to the utmost.

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 미세먼지의 발생빈도가 잦아지고 또한 초미세먼지로 인한 호흡기 계통 질병 발생의 우려가 높아짐에 따라, 기존의 방충망만으로는 안심하고 창문을 열어 환기를 하는 것이 꺼려지고 있는 실정이다. 따라서 기존의 방충망의 기능인 해충차단은 물론이고 유해한 초미세먼지까지를 차단해 줄 수 있는 새로운 기능의 방충방진망의 개발이 절실하게 필요한 상황이다.Generally, a window of a residential building such as a house or an apartment is provided with a mesh screen insect net which can block insects such as mosquitoes and flies and is capable of ventilation. The material of this insect screen is widely used for various synthetic materials such as nylon and polyester, thin metal nets such as aluminum and stainless steel, and recently, various products using glass fiber. However, recently, the frequency of harmful fine dust that can flow into the room through the insect screen having a conventional insect-proofing function has become frequent, and the fear of respiratory system disease due to ultrafine dust has increased, It is a fact that it is reluctant to open windows to ventilate. Therefore, it is inevitable to develop a new insecticide / dustproof network that can block harmful ultrafine dust as well as insect blocking which is a function of the existing insect screening network.

본 발명은 주로 주거용 건물의 창틀에 부착하여 유해한 해충을 차단해주는 기능을 하는 기존의 방충망에 최근 새롭게 문제가 되고 있는 초미세먼지까지 차단이 될 수 있도록 나노 파이버를 방사하여 나노사이즈의 방진망을 형성시키고 이를 방충망의 표면에 단단히 고착시킴으로써, 방충의 기능은 물론이고 미세먼지의 차단기능 까지를 갖고 있으면서도 통기성이 있고 액체상태의 수분, 즉 빗물이 유입되지 않는 우수한 기능의 창문용 필터망(filtering mesh)으로 사용가능한 나노방진망을 제공하고자 한다.The present invention relates to an existing screening net that functions to block harmful pests by attaching to window frames of residential buildings, and nano-sized dust-free chains are formed by spinning nanofibers so that ultrafine dusts, By firmly fixing it on the surface of the insecticide network, it is a filtering mesh for windows which has not only insecticidal function but also function to block fine dust, but has air permeability and liquid water, that is, And to provide usable nanoinduced waveguides.

본 발명은 상기의 과제를 해결하고자, 폴리에스터실로 형성된 그물형태의 방충망 원단의 한쪽 면에 핫멜트 수지를 도트(dot)상으로 도포한 다음 나일론수지를 나노파이버(Nano Fiber)형태로 방사하여 초미세먼지를 차단할 수 있도록 공극 크기가 0.1~100 um 인 초미세 방진망을 형성시켰다. 그리고 이 나노방사면 위에 핫멜트 수지가 도트(dot)상으로 도포된 또 다른 방충망을 겹쳐서 열 압연롤러를 통과시킴으로써 도트(dot)상으로 도포된 핫멜트 수지가 열 접착롤러에 의해 용융 압착되어, 방사된 나노 그물망이 폴리에스터 방충망위에 단단히 고착될 수 있도록 제조한 초미세먼지 차단용 나노방진망을 제공한다.In order to solve the above-mentioned problems, the present invention provides a method for manufacturing a woven fabric comprising the steps of: applying a hot-melt resin on one surface of a mesh-type insect-control fabric formed of a polyester yarn in the form of a dot; spinning the nylon resin in the form of a nanofiber; An ultrafine dust-free network with a pore size of 0.1 to 100 μm was formed to block the dust. Then, another hot melt resin coated with hot melt resin is dot-laid on the nano radiating surface, and the hot melt resin coated on the dot is melted and pressed by the hot adhesive roller by passing the hot melt resin through the hot rolling roller, The present invention provides a nanodisperse network for blocking ultrafine dusts, which is manufactured so that the nano network can be firmly fixed on a polyester screening net.

본 발명의 나노방진망은 기존의 주거시설, 교육시설, 업무시설 등에 설치된 방충망을 대신 할 수 있을 뿐만 아니라 상시적으로 창문을 개방하여 자연통풍을 가능하게 해주면서도 실내로 유입될 수 있는 황사, 꽃가루, 미세먼지 등과 같은 유해한 입자를 유효하게 차단해 줌으로써 쾌적한 실내 환경을 유지할 수 있게 해준다. 또한 나노방진망의 투과 공극이 미세하여 빗물을 차단시켜 줄 수 있기 때문에 우천 시에도 창문을 닫을 필요가 없고, 방진망이 차단된 먼지 등에 의해 오염이 된 경우에도 방진망 표면에 물을 분사시킴으로써 손쉽게 이물질을 청소할 수 있다. 또한 유연한 합성 섬유사로 구성되어 있어서 필요한 크기로 쉽게 재단하여 필요한 용도에 사용이 가능하므로 창문용 방진망을 비롯하여 냉방기용 공기필터, 방진용 마스크 필터 등 다양한 분야로의 사용이 가능하다.The nano-damping network of the present invention can replace an insect screen installed in existing residential facilities, education facilities, business facilities, and also can open windows at all times to enable natural ventilation, It effectively blocks the harmful particles such as fine dust and so on, thereby maintaining a pleasant indoor environment. In addition, it is not necessary to close the window even in case of rainy weather because the permeation gap of the nano-dust-proof net can be finely cut off and rainwater can be blocked. Even if the dust-proofing network is contaminated by the blocked dust, water is sprayed on the surface of the dust- . It is composed of flexible synthetic fiber yarn, so it can be easily cut to the required size and used for necessary applications, so it can be used in various fields such as windscreen wiper, air filter for air conditioner and dust mask filter.
