본 발명은 다공성을 갖는 폴리테트라플루오로에틸렌 박막에 관한 것으로, 구체적으로는 오염방지/박리방지 조성물, 다공성 폴리테트라플루오로에틸렌 박막과 그 직물 및 다공성 폴리테트라플루오로에틸렌 박막의 오염방지/박리방지 가공처리방법에 있어서, 간단하고 쾌속한 제조방법으로 제작된 오염방지/박리방지 다공성 폴리테트라플루오로에틸렌 박막과 그 직물이 도포나 침지에 의해 다공성 폴리테트라플루오로에틸렌 박막이 적층되거나 결합된 오염방지/박리방지 조성물을 형성하고, 적당한 베이킹을 통해 완성품을 제작하며, 원래의 다공성을 유지하는 폴리테트라플루오로에틸렌 박막의 구조에 의해, 통기성, 투습성, 발수성, 발유성, 오염방지 성의 효과를 얻음은 물론, 직물에 결합 가능하고 전체 공정이 간단하면서도 쾌속한 것에 관한 것이다.The present invention relates to a polytetrafluoroethylene thin film having a porosity, specifically, an antifouling / peeling composition, a porous polytetrafluoroethylene thin film and its fabric, and an antifouling / peeling prevention of a porous polytetrafluoroethylene thin film In the processing method, antifouling / peel-off porous polytetrafluoroethylene thin film manufactured by a simple and rapid manufacturing method and pollution prevention in which the porous polytetrafluoroethylene thin film is laminated or bonded by coating or dipping thereof. By the structure of the polytetrafluoroethylene thin film that forms the anti-peel composition, prepares the finished product through proper baking, and maintains the original porosity, the effect of breathability, moisture permeability, water repellency, oil repellency, and pollution prevention is achieved. Of course, the thing that can be bonded to the fabric and that the whole process is simple and fast. The.

종래의 폴리테트라플루오로에틸렌은 테트라플루오로에틸렌(C2F4)을 중합하여 형성되고, 주로 탄소원자와 불소원자의 조성에 수소가 함유되어있지 않아 산소와 반응하지 않으며, 그 특성은 내열성, 내저온성, 내부식성, 비점착성, 저마찰계수 및 자기윤활성 등의 특성을 보이며, 폴리테트라플루오로에틸렌 자체는 쉽게 다른 물질과 융합하지 않음은 물론 다른 물질이 이것에 쉽게 점착되지 않으므로 널리 응용된다. Conventional polytetrafluoroethylene is formed by polymerizing tetrafluoroethylene (C2F4), and does not react with oxygen mainly because it does not contain hydrogen in the composition of carbon atoms and fluorine atoms, and its characteristics are heat resistance and low temperature resistance. , Corrosion resistance, non-adhesiveness, low friction coefficient and self-lubrication, and the like, polytetrafluoroethylene itself is not easily fused with other materials, it is widely applied because other materials are not easily adhered to it.

폴리테트라플루오로에틸렌이 이와 같은 여러 장점을 가지므로, 당업자가 이것을 가공하여 폴리테트라플루오로에틸렌으로 된 얇은 시트나 얇은 필름을 제작하되, 이것에 다공성을 부여하여 직물이나 비직물에 부착하면, 필터재나 다른 용도에 응용할 수 있는바, 그 예가 미국특허 5,234,739; 6,084,472; 5,750,242와 대만특허공고 제538164호, 592783호에 있다.Since polytetrafluoroethylene has many of these advantages, those skilled in the art can process it to produce a thin sheet or thin film of polytetrafluoroethylene, which gives it porosity and adheres to fabrics or non-woven fabrics. It can be applied to ash or other uses, for example, US Pat. No. 5,234,739; 6,084,472; 5,750,242 and Taiwan Patent Publication Nos. 538164 and 592783.

이상의 설명에서 알 수 있듯이, 가공처리된 폴리테트라플루오로에틸렌은 공업분야나 민생용품에 널리 응용되지만, 폴리테트라플루오로에틸렌을 원료로 하는 생산공정이 각각 다르고 특허로 보호되고 있는데, 그 예를 들면 미국특허 6,702,971, 6,852,223, 5,098,625, 6,228,477, 6,410,084, 6,676,993, 6,854,603 및 4,096,227이 있다. As can be seen from the above description, the processed polytetrafluoroethylene is widely applied to industrial fields or consumer products, but the production process using polytetrafluoroethylene as a raw material is different and protected by patents. US Patents 6,702,971, 6,852,223, 5,098,625, 6,228,477, 6,410,084, 6,676,993, 6,854,603 and 4,096,227.

이와 같은 공정이나 이 공정으로 제작된 제품은 최후로 얻어진 폴리테트라플루오로에틸렌의 얇은 시트나 필름에 다공성을 부여하고 이를 의류에 적용하면 통기성, 투습성 및 발수성이 우수하다. Such a process or a product produced by this process imparts porosity to the thin sheet or film of polytetrafluoroethylene obtained last and is excellent in breathability, moisture permeability and water repellency when applied to clothing.

그러나, 이런 종래의 기술에서는 오염방지성, 발유성 및 박리방지성을 고려하지 않고 있으며, 의류의 오염에 있어서 가장 처리가 어려운 분야는 기름으로 오염되거나 의류에 스며든 때를 세척할 경우인데, 이 경우 세척을 위해서는 전용 세정제를 사용해야만 하고, 이 경우 이 세정제가 인체의 피부에 장시간 접촉되어 피부를 자극하고, 최악의 경우 인체 피부에 손상을 줄 우려가 있다. However, these conventional techniques do not consider anti-fouling, oil repellency and anti-separation properties, and the most difficult field in the contamination of clothing is when washing the soil contaminated with oil or seep into clothing. In this case, a dedicated cleaning agent must be used for washing, in which case the cleaner may be in contact with the skin of the human body for a long time, irritating the skin, and in the worst case, may damage the human skin.

장시간이 지나도 의류 표면이 청결해지지 않는데, 설사 표면이 청결해 보일지라도 실제로는 그렇지 않고, 특히 통기성과 투습성을 강조한 의류라면 때가 의류의 미세한 구멍에 끼워지던가 장시간의 퇴적에 의해 구멍이 막혀 의류의 원래의 통기성과 투습성을 상실하게 된다. Even after a long period of time, the surface of the garment does not become clean, even if the surface looks clean, but in reality it is not. Loss of breathability and breathability.

뿐만 아니라, 장시간의 물세탁에 의해 의류의 표면이나 섬유의 조직에 박리현상이 발생하여 발수성도 상실하게 된다. In addition, peeling may occur on the surface of the garment or the tissue of the fiber due to prolonged washing of water, resulting in loss of water repellency.

또, 미국특허 6,419,804와 대만특허 1,232,229에 의하면 오염방지막의 형성방법과 오염방지재료가 표면처리업이나 건축업, 자동차업(알미늄 휠이나 차체), 광학공업, 정밀기계업, 정보업(DVD, CD, CD) 및 플라스틱이나 고무 제품(타이어) 등에 응용되고 있는데, 이런 오염방지 박막은 특허에 기재된 오염방지효과는 보이지 만 통기성과 투습성은 보이지 않는다. In addition, according to U.S. Patent 6,419,804 and Taiwan Patent 1,232,229, the method of forming the anti-fouling film and the anti-pollution material include surface treatment, construction, automobile industry (aluminum wheel or body), optical industry, precision machinery, information industry (DVD, CD, CD). ) And plastic or rubber products (tires), etc. These anti-contamination thin films show the anti-pollution effect described in the patent but are not breathable and breathable.

이와 같은 종래 기술에서 알 수 있듯이, 오염방지기능을 갖는 박막이나 완성품은 통기성과 투습성을 상실하거나, 반대로 통기성과 투습성을 가지면 오염방지/박리방지 기능을 상실한다. As can be seen in the prior art, a thin film or a finished product having an antifouling function loses air permeability and moisture permeability, or conversely, when it has air permeability and moisture permeability, it loses antifouling / anti-peeling function.

이때문에, 상기 2종류의 다른 특성을 갖는 박막에 대해, 통기성, 투습성, 발수성, 발유성 및 오염방지성을 실현하는 외에, 박리방지성을 가짐은 물론, 공정의 간소화와 제품의 안전성 향상을 도모해 불량율을 낮추는 것이 시급한 과제이다. For this reason, the thin film having the two kinds of different characteristics can achieve breathability, moisture permeability, water repellency, oil repellency, and antifouling properties, as well as prevent peeling, simplifying the process and improving product safety. It is an urgent task to aim at reducing the defective rate.

본 발명의 주목적은 발수성, 발유성 및 방수성을 갖는 오염방지/박리방지 조성물과, 이 조성물을 응용하여 통기성, 투습성, 발수성, 발유성, 오염방지성, 박리방지성 및 방수성을 갖는 다공성 폴리테트라플루오로에틸렌 박막 및 그 직물을 제공하는데 있다.The main object of the present invention is an antifouling / peel-off composition having water repellency, oil repellency and water resistance, and porous polytetrafluorocarbon having application of the composition to breathability, moisture permeability, water repellency, oil repellency, antifouling, anti-peel and waterproof. To provide a low ethylene thin film and its fabric.

본 발명의 다른 목적은 통기성, 투습성 및 발수성은 물론, 오염방지성, 발유성, 박리방지성 및 방수성을 직물이나 의복이나 이런 효과를 필요로 하는 물건에 부여하여, 물세탁으로 때를 제거할 수 있는 다공성 폴리테트라플루오로에틸렌 박막과, 여러번 물세탁을 하여도 박리방지 효과를 가져 높은 통기성과 투습성, 발수성, 발유성 및 오염방지성을 갖는 다공성 폴리테트라플루오로에틸렌 박막 및 그 직물을 제공하는데 있다. It is another object of the present invention to impart breathability, moisture permeability and water repellency, as well as anti-fouling, oil repellency, anti-peel and waterproof properties to fabrics or clothes or objects requiring such effects, and can be removed by washing with water. The present invention provides a porous polytetrafluoroethylene thin film, and a porous polytetrafluoroethylene thin film and its fabric having high air permeability, moisture permeability, water repellency, oil repellency, and anti-fouling properties due to peeling effect even after several times of washing with water. .

이와 같은 목적달성을 위해, 본 발명은 도포나 침지의 가공방식에 의해, 폴 리테트라플루오로에틸렌 박막에 오염방지/박리방지 조성물을 결합한 다음, 베이킹 공정을 통해 통기성, 투습성, 발수성, 발유성, 오염방지성 및 박리방지성을 갖는 다공성 폴리테트라플루오로에틸렌 박막을 제공한다. In order to achieve the above object, the present invention combines the antifouling / peel-off composition to the polytetrafluoroethylene thin film by the coating or dipping process, and then breathe, moisture permeability, water repellency, oil repellency, Provided is a porous polytetrafluoroethylene thin film having antifouling and anti-peeling properties.

다공성을 갖는 폴리테트라플루오로에틸렌 박막을 고배열 전자현미경으로 관찰하면, 섬유와 노드로 이루어지며, 다른 온도나 연신율에 의하면 섬유와 노드가 분명히 다르고, 보다 큰 배율로 연신하면 기존의 섬유 길이를 연신하지 않고 섬유끼리 연결하는 노드가 다시 보다 미세한 섬유와 보다 작은 노드로 분열됨으로써, 소위 마이크로미터급 섬유 박막이나 나노급 섬유 박막이 형성되며, 이 박막을 직물이나 의류에 응용하면, 직물이나 의류가 통기선, 투습성, 발수성을 갖게된다. Polytetrafluoroethylene thin films with porosity are observed by high-array electron microscopy, which are composed of fibers and nodes, and the fibers and nodes are clearly different according to different temperatures or elongations. Instead, the nodes connecting the fibers to each other are divided into finer fibers and smaller nodes, so that a so-called micrometer-fiber or nano-fiber thin film is formed. Steamer, moisture permeability, water repellency.
