Description
본 발명은 필터용 부직포 및 그를 이용한 필터 카트리지에 관한 것으로, 보다 상세하게는 부직포 기재에 아민 기가 부가되어, 가공 및 취급시 분진 발생이 없으면서도 아민 부가량이 높아 우수한 바이러스 제거성능을 갖는 필터용 부직포 및 그를 이용한 카트리지 필터에 관한 것이다.The present invention relates to a filter nonwoven fabric and a filter cartridge using the same. More specifically, an amine group is added to a nonwoven fabric substrate, and thus, a filter nonwoven fabric having a high virus removal performance without high dust content during processing and handling, and having excellent virus removal performance. It relates to a cartridge filter using the same.
21세기는 수질 및 환경오염, 물사용량의 지속적인 증가, 가뭄으로 인한 물부족과 물분쟁 등이 현안과제로 대두되는 실정이다. 또한 각종 박테리아와 바이러스에 의한 수질 오염으로 인간의 생명에 위협이 되고 있다. 이에 따라 박테리아나 바이러스를 제거할 수 있는 필터의 수요가 증가하고 있다.In the 21st century, water and environmental pollution, continuous increase in water consumption, water shortage due to drought, and water disputes are emerging issues. In addition, water pollution by various bacteria and viruses is threatening human life. Accordingly, the demand for filters that can remove bacteria or viruses is increasing.
기능성 물질을 함유한 여재의 개발을 위하여 일반적으로 제시되는 방법으로는 기능성 물질을 스프레이 코팅하거나, 별도의 기능성 물질의 층을 추가하는 등의 방법을 적용하고 있다. 그러나 상기 기능성 물질의 코팅의 경우에는 기능성 물질이 여재의 표면에 얹혀져 있거나 접착제 등으로 부착되는 형태로 구성이 되므로 기능성 물질의 여재에 대한 부착이 견고하지 못하고, 접착물질을 사용하는 경우에는 접착제가 발생시키는 2차 오염을 피할 수 없는 문제점이 있다. 또한 여재를 오랫동안 사용하는 경우에 기능성 물질이 떨어져 나와 기능성 효과가 줄어들게 됨은 물론이고, 기능성 물질의 입자가 2차 오염원으로 작용할 수 있는 문제점이 있다.In general, methods for the development of a medium containing a functional material include spray coating a functional material or adding a layer of a separate functional material. However, in the case of the coating of the functional material is formed in the form of the functional material is placed on the surface of the media or attached with an adhesive, etc., the adhesion of the functional material to the media is not firm, the adhesive occurs when using the adhesive material There is a problem that can not be avoided secondary pollution. In addition, in the case of using the filter for a long time, the functional material falls off and the functional effect is reduced, as well as the problem that the particles of the functional material can act as a secondary pollution source.
또한, 기능성 물질로 구성된 별도의 층을 제조하여 추가하는 방법의 경우에는 기능성 물질이 고가의 물질이고, 대개 표면반응을 통하여 살균, 정화 등의 기능을 수행하는 데 비하여 상기와 같이 별도의 층을 제조하는 경우에는 기능성 물질의 비표면적이 상대적으로 적어 동일한 기능을 발휘하기 위해서는 많은 양의 기능성 물질을 요구하므로 기능성 물질층의 제조단가가 높아지고, 기능성 물질을 다량 포함하고 있음에도 불구하고 실제에 있어서 정화기능을 충분히 발휘하지 못하여 기능성 물질의 활용도가 떨어지는 문제점이 있다.In addition, in the case of adding a separate layer composed of a functional material, the functional material is an expensive material, and in general, a separate layer is prepared as described above, compared to performing functions such as sterilization and purification through surface reactions. In this case, since the specific surface area of the functional material is relatively small, a large amount of the functional material is required to perform the same function, thereby increasing the manufacturing cost of the functional material layer, and despite the fact that it contains a large amount of the functional material, There is a problem that the utilization of the functional material is insufficient because it does not sufficiently exhibit.
현재 상용화되고 있는 바이러스 제거용 필터로는 아르고나이드(Argonide)사의 NanoCeram
이에 본 발명자들은 이러한 정전기적 흡착 메커니즘을 고분자 부직포에 도입하면 상술한 상용의 바이러스 제거용 필터여재의 단점을 극복할 수 있음을 확인하고 본 발명을 완성하기에 이르렀다. Accordingly, the present inventors have confirmed that the introduction of the electrostatic adsorption mechanism into the polymer nonwoven fabric can overcome the disadvantages of the above-described commercial filter medium for virus removal, and have completed the present invention.

본 발명의 다른 목적은 상기 부직포를 이용한 필터 카트리지를 제공하는 것이다.Another object of the present invention is to provide a filter cartridge using the nonwoven fabric.
상기 목적을 달성하기 위한 본 발명의 바이러스 제거성능을 가지는 필터용 부직포는 부직포 기재에 아민기가 부가된 것이다.The filter nonwoven fabric having a virus removal ability of the present invention for achieving the above object is an amine group is added to the nonwoven fabric substrate.
상기 부직포의 소재는 폴리에틸렌, 폴리아미드, 폴리비닐클로라이드 및 폴리에틸렌테레프탈레이트로 구성된 군으로부터 선택되는 하나 이상인 것이 바람직하다.The material of the nonwoven fabric is preferably at least one selected from the group consisting of polyethylene, polyamide, polyvinylchloride and polyethylene terephthalate.

상기 아민기의 부가량은 1~10 mmol/g인 것이 바람직하다.It is preferable that the addition amount of the said amine group is 1-10 mmol / g.
본 발명의 바이러스 제거 필터용 부직포는 섬유를 기재로 하고 있어 가공 및 취급시 분진 발생이 없으면서도 아민 부가량이 높아 바이러스 제거성능이 우수하다. The nonwoven fabric for virus removal filter of the present invention is based on fibers, and has a high amount of amine addition and excellent virus removal performance without generating dust during processing and handling.
본 발명의 필터용 부직포는 부직포 기재에 암모니아 또는 아민기가 부가되어 친수성을 가지는 것을 특징으로 한다.The filter nonwoven fabric of the present invention is characterized in that ammonia or an amine group is added to the nonwoven fabric base to have hydrophilicity.
본 발명에서 기재로 사용되는 부직포라 함은 고분자 소재의 장섬유나 단섬유 상의 섬유 또는 필라멘트를 서로 꼬이도록 하여 평평하고 다공성을 갖도록 시트상이나 웹상의 구조로 접착한 것을 말한다. 접착 방법에는 기계적, 화학적 또는 열접착 방식 등이 사용될 수 있다는 것은 당업계의 관용기술이다.The nonwoven fabric used as a substrate in the present invention refers to a sheet or web-like structure that is flat and porous by twisting fibers or filaments of long fibers or short fibers of a polymer material with each other. It is common practice in the art that mechanical, chemical or thermal bonding methods can be used for the bonding method.
본 발명의 기재 부직포로 사용될 수 있는 고분자 소재는 필터용으로 사용되는 당업계의 관용적인 것을 사용할 수 있으나, 바람직하게는 폴리프로필렌, 폴리에틸렌, 폴리아미드, 폴리비닐클로라이드 및 폴리에틸렌테레프탈레이트로 구성된 군으로부터 선택되는 하나 이상이 후술하는 코로나 방전등으로 용이하게 아민기를 부가시킬 수 있어 바람직하다.The polymeric material which can be used as the base nonwoven fabric of the present invention can be used conventionally used in the filter, but is preferably selected from the group consisting of polypropylene, polyethylene, polyamide, polyvinylchloride and polyethylene terephthalate It is preferable that at least one of the amine groups can be easily added by a corona discharge described later.
본 발명의 필터용 부직포는 상기 기재로 사용되는 부직포에 암모니아 또는 아민기(이하 '아민'으로 통칭함)가 부가되어 제조된 것이다. 부가된 아민은 인체에 유해한 소독부산물을 발생시킬 수 있는 잔류염소와 반응하여 무해한 염소이온으로 변환시키는 기능을 한다. 본 발명에서 아민이라 함은 암모니아를 구성하는 수소원자 중의 하나 이상이 알킬기 또는 아릴기로 치환된 유기화합물을 말한다. 상기 알킬기로서 바람직하게는 C1~C5의 직쇄상, 분지상 또는 환상의 포화 또는 불포화 탄화수소를 사용하며, 상기 아릴기로서 바람직하게는 치환되거나 벤젠환을 갖는 C6~C10의 탄화수소를 사용한다. 보다 바람직하게는 암모니아, 디에틸아민, 트리에틸아민, 에탄올아민, 에틸렌디아민, 아닐린으로 이루어지는 군에서 선택된 하나 이상을 사용한다.The filter nonwoven fabric of the present invention is prepared by adding ammonia or an amine group (hereinafter referred to as 'amine') to the nonwoven fabric used as the substrate. The added amines function to react with residual chlorine, which can generate disinfection by-products that are harmful to the human body and convert them into harmless chlorine ions. In the present invention, the amine refers to an organic compound in which at least one hydrogen atom constituting ammonia is substituted with an alkyl group or an aryl group. As said alkyl group, C1-C5 linear, branched or cyclic saturated or unsaturated hydrocarbon is used preferably, and as said aryl group, C6-C10 hydrocarbon which has a substituted or benzene ring preferably is used. More preferably, at least one selected from the group consisting of ammonia, diethylamine, triethylamine, ethanolamine, ethylenediamine and aniline is used.
한편, 상기 아민은 C1~C10 및 N2~N5의 폴리아민일 수 있다. 폴리아민이라 함은 하나의 아미노기를 갖는 화합물을 말한다. 상기 폴리아민의 예로서는 에틸렌디아민, 1,3-디아미노프로판, 헥사메틸렌디아민, 디에틸렌트리아민, 트리에틸렌테트라아민, 테트라에틸렌펜타아민, 이미다졸리딘, 피페라진 등이 있다.On the other hand, the amine may be a polyamine of C1 ~ C10 and N2 ~ N5. The polyamine refers to a compound having one amino group. Examples of the polyamine include ethylenediamine, 1,3-diaminopropane, hexamethylenediamine, diethylenetriamine, triethylenetetraamine, tetraethylenepentaamine, imidazolidine, piperazine and the like.
한편, 상기 아민기에는 하나 이상의 다른 관능기, 예를 들어, 히드록시기, 티올기와 같은 관능기를 가질 수 다. 히드록시 관능기를 갖는 아민의 예로서는 에탄올아민, 디에탄올아민 등이 있으며, 이들은 모포린과 같이 환형일 수 있다.On the other hand, the amine group may have one or more other functional groups, for example, functional groups such as hydroxy groups, thiol groups. Examples of amines having hydroxy functional groups include ethanolamine, diethanolamine, and the like, which may be cyclic such as morpholine.
상기 아민은 기재로 사용되는 부직포에 부가되어 있다. 본 발명에서 부가라 함은 공유결합, 이온 결합, 수소결합 또는 이들의 조합형태로 상기 아민이 기재로 사용된 부직포의 고분자 사슬에 화학적으로 결합되는 것을 말한다. 한편, 아민기가 기재로 사용되는 부직포 고분자 소재와 결합되는 위치는 아민기를 구성하는 원자 중에 질소 또는 탄소일 수 있다. 상기 아민의 부가량은 1~10 mmol/g 인 것이 바람직하다. 아민기의 부가량이 1 mmol/g에 이르지 못하면 충분한 기능을 발휘할만큼의 아민기가 부족한 문제점이 있고, 10 mmol/g을 초과하는 경우에는 부직포 표면에 아민의 부착이 어려우며 아민의 탈리현상이 발생하는 문제점이 있어 바람직하지 않다.
The amine is added to the nonwoven fabric used as the substrate. Addition in the present invention means that the amine is chemically bonded to the polymer chain of the nonwoven fabric used as a substrate in the form of a covalent bond, an ionic bond, a hydrogen bond or a combination thereof. On the other hand, the position where the amine group is bonded to the nonwoven polymer material used as the substrate may be nitrogen or carbon in the atoms constituting the amine group. It is preferable that the addition amount of the said amine is 1-10 mmol / g. If the added amount of the amine group does not reach 1 mmol / g, there is a problem that the amine group is insufficient to exhibit sufficient function. If the amount of the amine group exceeds 10 mmol / g, it is difficult to attach the amine to the surface of the nonwoven fabric and the desorption of the amine occurs. This is undesirable.
본 발명의 아민기가 부가된 필터용 부직포는 바이러스 제거에 유용하다. 본 발명에 의하여 제거될 수 있는 바이러스로는 MS2 phage, Bacillus subtilis, 엔도톡신, 바이오해저드, 탄저균, 천연두, 황색포도상구균, 녹농균 등이 있다. The filter nonwoven fabric to which the amine group of this invention was added is useful for virus removal. Viruses that can be removed by the present invention include MS2 phage, Bacillus subtilis, endotoxin, biohazard, anthrax, smallpox, Staphylococcus aureus, Pseudomonas aeruginosa, and the like.
한편, 본 발명의 아민기가 부가된 부직포는 아민기가 부착되는 기재가 섬유상인 부직포이므로 제조과정, 취급과정에서 기재가 유리섬유 등인 경우에 비하여 분진이 발생하지 않는다는 장점이 있다. 대부분의 바이러스는 정전기적으로 음성의 상태로 존재한다. 본 발명에서는 필터용 부직포에 정전기적으로 양성인 아민기를 도입함으로써 정전기적 인력에 의하여 바이러스를 포획하게 된다
On the other hand, since the non-woven fabric to which the amine group is added is a fibrous nonwoven fabric to which the amine group is attached, there is an advantage that dust does not occur as compared to the case where the substrate is glass fiber or the like in the manufacturing process or handling process. Most viruses are electrostatically negative. In the present invention, the virus is captured by the electrostatic attraction by introducing an electrostatically positive amine group into the filter nonwoven fabric.
본 발명의 필터용 부직포는 기재가 되는 부직포를 적절한 방법으로 표면처리를 한 다음에 상술한 아민을 가스상태에서 접촉시키는 방법으로 아민기가 부가되어 제조될 수 있다. 표면처리의 방법으로는 코로나처리, 방사선 처리, 플라즈마 처리 등이 있으나 이에 제한되는 것은 아니다. 상기 표면처리가 부직포와 아민가스를 접촉시킨 상태에서 수행되어, 부직포를 구성하는 고분자 소재에 라디칼 등의 활성기가 생성되는 즉시 아민기와 반응하도록 구성될 수 있다.
The filter nonwoven fabric of the present invention can be prepared by adding an amine group by surface treatment of the nonwoven fabric serving as a substrate by a suitable method and then contacting the amine described above in a gaseous state. Surface treatment methods include, but are not limited to, corona treatment, radiation treatment, plasma treatment, and the like. The surface treatment may be performed while contacting the nonwoven fabric with the amine gas, and may be configured to react with the amine group as soon as active groups such as radicals are generated in the polymer material constituting the nonwoven fabric.
본 발명의 바이러스 제거성능을 가지는 필터용 부직포는 2겹 이상 연속적으로 합지하는 것을 통하여 다층구조로 제조 될 수 있다. 이러한 필터용 부직포는 침전필터(Sediment Filter), 역삼투막 필터(Membrane Filter)와 결합되어 카트리지로 제조된다.
The filter nonwoven fabric having the virus removal ability of the present invention may be manufactured in a multi-layered structure through two or more layers of continuous lamination. The filter nonwoven fabric is combined with a sediment filter and a reverse osmosis membrane filter to produce a cartridge.
이하, 본 발명을 실시예에 의하여 상세히 설명한다. 하기 실시예는 본 발명을 예시하는 것일 뿐, 본 발명의 범위가 하기 실시예에 한정되는 것은 아니다.

1. 아민 부착량1.Amine Attachment Amount
플라즈마 처리 전 부직포의 질량을 W1, 플라즈마 처리 후 부직포의 질량을 W2, 플라즈마 처리에 사용된 아민의 분자량을 M2 라고 했을 때 아민의 부착량을 다음 식을 통하여 계산하였다.When the mass of the nonwoven fabric before the plasma treatment was W1, the mass of the nonwoven fabric after the plasma treatment was W2, and the molecular weight of the amine used in the plasma treatment was M2, the adhesion amount of the amine was calculated through the following equation.
부착량 = (W2-W1)/W2M2 X 1000 [mmol/g]Coating Weight = (W2-W1) / W2M2 X 1000 [mmol / g]
2. 수투과율2. Water transmittance
수투과율 측정은 Milipore사의 평막수투과도장치(catalog no. XX6700P10)를 이용하였다. 실시예, 비교예들에서 제조된 부직포를 10매 겹친 다음, 47cm2의 단면적, 1bar의 정압에서 1분을 단위로 투과되는 물의 양을 측정하였다.Water permeability was measured using a Milipore's flat membrane water permeation apparatus (catalog no. XX6700P10). 10 nonwoven fabrics prepared in Examples and Comparative Examples were laminated, and then the amount of water permeated in units of 1 minute at a cross-sectional area of 47 cm 2 and a constant pressure of 1 bar was measured.
3. 바이러스 제거율3. Virus Removal Rate
상기 평막수투과도장치를 이용하여, 부직포를 통과하기 전과 후의 바이러스 농도를 측정하여 바이러스 제거능을 평가하였다. 실시예, 비교예들에서 제조된 부직포를 10매 겹친 다음, 47cm2의 단면적, 1bar의 정압에서 PFU/ml(PFU : plaque forming units)단위로 8x105/ml 으로 희석한 바이러스(MS2 phage) 용액을 투과시켜 제거성능을 평가하였다.Using the flat membrane water permeation apparatus, virus removal ability was evaluated by measuring the virus concentration before and after passing through the nonwoven fabric. 10 non-woven fabrics prepared in Examples and Comparative Examples, and then virus (MS2 phage) solution diluted to 8 × 10 5 / ml in units of PFU / ml (PFU: plaque forming units) at a cross-sectional area of 47 cm 2 and static pressure of 1 bar. The removal performance was evaluated by permeation.

상기 표를 참조하면, 저온유도 플라즈마 처리를 하지 않은 부직포의 경우 바이러스 제거가 거의 이루어지지 않는 것에 비해, 저온유도 플라즈마 처리를 한 부직포의 경우 바이러스 제거율이 현저하게 향상되며 실시예 2에서는 바이러스 제거가 99.9% 이루어지는 것을 확인할 수 있다.
Referring to the above table, the virus removal rate is significantly improved in the case of the non-woven fabric which has not been subjected to the low temperature-induced plasma treatment, whereas the virus removal is significantly improved in the non-woven fabric which has been subjected to the low-temperature-induced plasma treatment. % Can be confirmed.
