An air filter support with a honeycomb network structure that can reduce energy input and carbon dioxide generation, replace existing cylindrical air filter supports, and can be effectively applied to air conditioners or air purifiers through thin, light and endowed functionality, and a method for manufacturing the same It is about.

최근 황사 및 미세먼지에 의한 대기오염 문제가 지속되면서 이에 대응하기 위한 필터의 성능향상에 대한 관심이 높아지고 있고 있으며, 공기청정기를 비롯하여 에어컨과 같은 다양한 공조기에 고성능의 필터가 적용되고 있으며, 특히 여과효율 및 필터수명을 향상시키기 위해 프리필터(Pre Filter), 미디움필터(Medium Filter), 헤파필터(Hepa Filter)를 조합한 다중의 여과방식을 채용하고 있다.Recently, as air pollution caused by yellow dust and fine dust continues, interest in improving the performance of filters to cope with them is increasing, and high-performance filters are applied to various air conditioners such as air purifiers and air conditioners. And in order to improve the life of the filter, a multiple filtration method combining a pre filter, a medium filter, and a HEPA filter is adopted.

In other words, there is no major problem in satisfying air permeability, but it was difficult to satisfy detailed requirements such as abrasion resistance, durability, and appearance.

본 발명에서 첫 번째 단계(S110)는 매시 구조의 제직물 제조를 위한 원사(10)를 준비하는 단계로, 구체적으로는 용융점 250 내지 270℃ 특성을 갖는 폴리에스터 재질의 심사(11) 및 상기 심사(11)를 둘러싼 겉면에 용융점 150 내지 170℃ 특성을 갖는 폴리에스터 재질의 코팅층(12)으로 이루어지는 원사(10)를 준비한다.In the present invention, the first step (S110) is a step of preparing the yarn 10 for manufacturing a woven fabric having a mesh structure, specifically, the screening 11 of polyester material having a melting point of 250 to 270 ° C and the screening Prepare a yarn 10 made of a coating layer 12 of a polyester material having a melting point of 150 to 170 ° C. on the outer surface surrounding (11).

즉 첨부된 도 3과 같이 상기 원사(10)는 중앙(Core Part)은 폴리에스터 심사(11), 겉면(Sheath Part) LM(Low melting) 폴리에스터 코팅층(12) 구조로, 바람직하게는 코어 심사(11)의 녹는점은 약 260℃, 겉면 LM 코팅층(12)의 녹는점은 약 160℃으로 하여 코팅층의 용융온도에서 심사는 녹지 않도록 구성하게 된다.That is, as shown in the attached FIG. 3, the center (Core Part) of the yarn 10 has a polyester screening 11 and an outer surface (Sheath Part) LM (Low melting) polyester coating layer 12 structure, preferably a core screening The melting point of (11) is about 260 ° C, and the melting point of the outer LM coating layer 12 is about 160 ° C, so that the core does not melt at the melting temperature of the coating layer.

이와 같이 심사(11)를 구성하는 고융점 폴리에스터 및 코팅층(12)을 구성하는 저융점 폴리 에스터는 시판되는 제품을 통해 입수하여 사용하게 되며, 저융점 폴리에스터 성분과 고융점 폴리에스터 성분의 질량비율은 80~20:20~80 정도로 구성할 수 있다. 만약 저융점 폴리에스터 성분의 비율이 20 질량% 미만이면, 융착력이 약해질 수 있고, 고융점 폴리에스터 성분의 비율이 20 질량% 미만이면, 원사의 강도가 저하될 수 있다.In this way, the high melting point polyester constituting the screening 11 and the low melting point polyester constituting the coating layer 12 are obtained and used through commercially available products, and the mass of the low melting point polyester component and the high melting point polyester component The ratio can be configured as 80~20:20~80. If the proportion of the low melting point polyester component is less than 20% by mass, the bonding strength may be weakened, and if the proportion of the high melting point polyester component is less than 20% by mass, the strength of the yarn may be reduced.

또한, 이와 같이 원사를 제조하는 공정 중에 아황산칼슘 입자를 5 ~ 10 중량% 첨가함으로 인체에 유해하거나 기계장비 및 시설물 등에 해로운 염소나 기타 산화성 물질들을 제거할 수 있다.In addition, by adding 5 to 10% by weight of calcium sulfite particles during the yarn manufacturing process, chlorine or other oxidizing substances harmful to the human body or harmful to mechanical equipment and facilities can be removed.

이후 원사의 제직 전 빔에 원사를 감는 정경작업이 이루어지고 다음 두 번째 단계(S120)에서는 준비된 원사를 위사 및 경사로 배치하고 제직하여 벌집망 구조를 형성하게 된다. 벌집망은 러셀망으로도 불리며 이미 벌집망 관련 제품 및 제직방법은 공지되었으므로 종래의 방식을 통해 원사를 제직하되 필요에 따라 적정한 규격의 망 크기를 갖도록 벌집망 구조를 만들게 된다.Thereafter, a warping operation of winding the yarn around the beam before weaving of the yarn is performed, and in the second step (S120), the prepared yarn is arranged in weft and warp yarns and weaved to form a honeycomb network structure. The honeycomb network is also called a Russell network, and since honeycomb network-related products and weaving methods are already known, the yarn is woven through a conventional method, but the honeycomb network structure is made to have a mesh size of an appropriate standard as needed.

이후, 상기 제직물을 기능성 물질과 결합시키는 기능성 부여 단계(S131)를 거칠 수 있다. Thereafter, a functional imparting step (S131) of combining the woven fabric with a functional material may be performed.

구체적으로 상기 제직물을 밀폐된 챔버에 넣어 감압하고 기화된 기능성 물질과 공급 후 가열함으로 상기 기능성 물질과 제직물을 결합시키는 것으로, 기능성 물질이라 함은 본 발명이 에어컨이나 공기청정기에 적용되는 필터용으로 활용됨에 따라 항균기능, 탈취기능, 광촉매가 될 수 있다.Specifically, the functional material and the woven fabric are combined by putting the woven fabric in an airtight chamber to depressurize and heating after supplying the vaporized functional material, and the functional material refers to a filter for which the present invention is applied to an air conditioner or air purifier. It can be used as an antibacterial function, deodorizing function, and photocatalyst.

대표적인 상기 항균기능물질은 카테킨, β-카로틴 또는 Ag+, Cu2+, Zn2+ 과 같은 항균성 금속이온을 비롯하여 은 입자 또는 은 나노입자 등이 사용될 수 있고, 탈취 기능물질에는 제올라이트, 활성탄소분말, 활성탄소섬유, 개질된 활성탄소분말, 개질된 활성탄소섬유 또는 탄소나노튜브 등이 적용될 수 있다. 또한, 광촉매 물질로는 이산화티탄을 들 수 있다. Representative of the antibacterial functional material may be catechin, β-carotene or antibacterial metal ions such as Ag+, Cu2+, Zn2+, silver particles or silver nanoparticles, and deodorizing functional materials include zeolite, activated carbon powder, activated carbon fiber, Modified activated carbon powder, modified activated carbon fibers or carbon nanotubes may be applied. In addition, titanium dioxide may be mentioned as a photocatalytic material.

이러한 기능성 물질은 용액형태로 만들되 필요시 적절한 바인더와 혼합하여 진공 챔버 내에서 가열하며 제직물과 결합시킨다.These functional materials are made in the form of a solution, but mixed with an appropriate binder if necessary, heated in a vacuum chamber, and combined with the woven fabric.

이때 가열 온도는 상기 심사 및 코팅층이 녹지 않는 온도범위에서 기능성 물질의 부착이 용이한 80℃ 내지 90℃ 온도가 될 수 있으며, 챔버의 완전 진공을 위한 운용부담 감소를 위해 60mmHg~400mmHg 정도의 저진공 상태로 챔버를 운용할 수 있다.At this time, the heating temperature may be 80 ° C to 90 ° C, which facilitates the attachment of functional materials in the temperature range in which the screening and coating layers do not melt, and a low vacuum of about 60 mmHg to 400 mmHg to reduce the operating burden for complete vacuum of the chamber. chamber can be operated.

다음 제직물을 완성하는 단계(S130)에서는 제직된 매시 구조를 170 내지 190℃에서 30 내지 60초 동안 열처리하여 위사 및 경사의 교차점을 융착시켜 제직물을 완성하게 된다. 바람직하게는 180℃ 온도로 열 처리함으로 제직물의 위사, 경사 교차지점의 코팅층이 녹아 융착되어 원단 고정이 이루어지며 원단의 형태안정성이 확보되며 올 풀림 및 올 터짐이 방지된다.In the step of completing the next woven fabric (S130), the woven mesh structure is heat treated at 170 to 190 ° C. for 30 to 60 seconds to fuse the intersections of the weft and warp yarns to complete the woven fabric. Preferably, by heat treatment at a temperature of 180 ° C, the coating layer at the intersection of the weft and warp yarns of the woven fabric is melted and fused to fix the fabric, secure the shape stability of the fabric, and prevent fraying and fraying.

다음으로, 상기 제직물을 절단 후 성형하여 에어필터 지지체를 제작하는 단계(S140)가 진행된다.Next, a step of manufacturing an air filter support by cutting and shaping the woven fabric (S140) proceeds.

도 5는 본 발명의 실시예에 따른 지지체가 적용된 에어필터를 나타낸 사시도로서, 공기청정기에 사용되는 원통형 필터의 지지체로 벌집망 구조의 제직물을 구성하는 모습을 도시하고 있다.5 is a perspective view showing an air filter to which a support is applied according to an embodiment of the present invention, and shows how a woven fabric having a honeycomb network structure is used as a support for a cylindrical filter used in an air cleaner.

앞서 언급한 바와 같이 종래에는 필터재의 형태를 잡아주기 위한 지지체로 허니콤 구조의 합성수지 구조체가 필터 중앙에 원통형으로 부착되는 것이 일반적인 형태로 지지체의 두께로 인한 부피뿐 아니라 공기의 저항을 높이는 문제가 있었다.As mentioned above, conventionally, as a support for holding the shape of the filter material, a synthetic resin structure having a honeycomb structure is generally attached to the center of the filter in a cylindrical shape, which has a problem of increasing air resistance as well as volume due to the thickness of the support. .

본 발명에 따른 벌집망 제직물(110)은 두께가 얇으면서도 필터재(120)의 형상지지를 위한 충분한 강도를 갖도록 할 수 있어, 한 겹 또는 여러 겹으로 원통 형상을 만들어 필터재의 중앙에 부착함으로 종래대비 두께 및 부피를 크게 줄일 수 있을 뿐 아니라 공기 저항성에서도 매우 유리한 효과를 나타낼 수 있다.The honeycomb woven fabric 110 according to the present invention can have sufficient strength to support the shape of the filter material 120 even though it is thin, so that it can be made into a cylindrical shape with one layer or several layers and attached to the center of the filter material. Not only can the thickness and volume be greatly reduced compared to the prior art, but also a very advantageous effect can be exhibited in terms of air resistance.

이때 복수의 층 구조로 제직물(110)을 구성할 경우 그 사이에 기능성층(130)을 삽입하여 필터의 성능을 높일 수 있다. 바람직하게는 정전 성능을 통해 공기 중 이물질이 부착될 수 있도록 정전특성이 우수하고 극세사로 제작 가능한 멜트블로운 (Melt Blown)방식으로 제조된 기능성층을 넣을 수 있다. 이러한 정전성 기능성층은 정전특성이 우수한 폴리프로필렌, 폴리에스터를 통해 제조될 수 있으며 앞서 언급한 기능성 물질을 상기 기능성층(130)에 결합시켜 사용할 수도 있다.In this case, when the woven fabric 110 is formed in a multi-layer structure, the performance of the filter may be improved by inserting the functional layer 130 therebetween. Preferably, a functional layer manufactured by a melt blown method, which has excellent electrostatic properties and can be made of microfibers, can be inserted so that foreign substances in the air can be attached through electrostatic performance. Such an electrostatic functional layer may be made of polypropylene or polyester having excellent electrostatic properties, and the aforementioned functional material may be combined with the functional layer 130 and used.
