본 발명은 투습방수용 코팅물, 코팅방법 및 이를 이용한 투습방수 직물에 관한 것으로 코팅층을 형성한 후에 직물을 접착하여 투습도 및 내수압이 우수한 투습방수용 코팅물, 코팅방법 및 그로 제조되는 투습방수 직물에 관한 것이다.
The present invention relates to a water-permeable waterproof coating, a coating method, and a water-permeable waterproof fabric using the same, and to a moisture-permeable waterproof coating, a coating method, and a water-permeable waterproof fabric having excellent moisture permeability and water resistance by adhering the fabric after forming a coating layer. .

일반적으로 투습방수 직물은 100㎛의 빗방울이 섬유 밖에서 섬유 안으로 통과 못하게 하고 몸의 체내에서 방출되는 0.004㎛의 수분을 섬유 안에서 섬유 밖으로 나갈 수 있도록 피막층을 직물위에 형성시켜 투습성과 방수성 등이 우수한 스포츠웨어, 군복, 텐트 등에 사용되는 직물을 의미한다.In general, moisture-permeable fabric is a sportswear that has excellent moisture permeability and waterproofness by forming a coating layer on the fabric so that raindrops of 100 μm do not pass into the fiber from the outside of the fiber and 0.004 μm of moisture released from the body can flow out of the fiber in the fiber. Means fabrics used in military uniforms, tents, etc.

투습방수 기능을 갖도록 하는 방법은 라미네이팅(Laminating) 방식에 의한 PTFE 미세다공 성막법과 다이렉트 코팅방식에 의한 폴리우레탄 미다공 성막법, 그리고 초고밀도 직쳔물에 의한 방법 등으로 크게 나눌 수 있다. 폴리우레탄을 이용한 다이렉트 코팅방식에 의한 종래의 투습방수직물은 DMF(디메칠포름아미드) 및 MEK(메틸에틸케톤) 등과 같이 환경에 유해한 솔벤트를 사용함으로써 환경오염을 초래하는 원인이 되어 최근에는 수분산형 폴리우레탄 코팅액을 이용하고 다단 건조하여 건식다공형 투습방수포를 제작법과 친수무공형의 폴리우레탄을 이용한 건식코팅법이 연구되고 있다.Methods to have a moisture-permeable waterproof function can be broadly divided into a PTFE microporous film forming method by the laminating method, a polyurethane microporous film forming method by the direct coating method, and a method using an ultra high density fabric. The conventional moisture-permeable waterproof fabric by direct coating method using polyurethane is the cause of environmental pollution by using environmentally harmful solvents such as DMF (dimethylformamide) and MEK (methyl ethyl ketone). The method of manufacturing a dry porous permeable waterproof fabric by using a polyurethane coating solution and drying in multiple stages and a dry coating method using a hydrophilic non-porous polyurethane have been studied.

친수무공형 폴리우레탄을 이용한 투습방수직물의 종래기술로써 대한민국 등록특허 제0795386호의 '친수무공형 투습방수포'에서는 폴리에틸렌글리콜(Polyethylene Glycol) 또는 폴리프로필렌글리콜(Polyprophylene Glycol)의 소프트세그먼트(soft segment)의 폴리올(Polyol)을 갖는 친수무공형 폴리우레탄 수지를 사용하여 건식코팅법에 의한 투습성이 우수한 방수포를 기재하였고, 대한민국 공개특허 제2008-0042309호는 '투습방수용 코팅조성물, 이를 이용한 건식무공형투습 방수원단 및 이의 제조방법'에는 친수무공형 폴리우레탄을 원단-코팅층의 2단계 제조공정으로 코팅하여 생산성 향상, 환경오염 감소 및 우수한 코팅 품질을 확보할 수 있는 코팅법을 제안한다.As a conventional technology of a moisture-permeable waterproof fabric using a hydrophilic non-porous polyurethane, in the 'hydrophilic non-porous moisture-proof cloth' of Korean Patent No. 0795386, a soft segment of polyethylene glycol or polyproplyylene glycol is used. Using a hydrophilic non-porous polyurethane resin having a polyol, a waterproof cloth having excellent moisture permeability by a dry coating method has been described. Fabric and its manufacturing method is proposed a coating method that can be coated with a hydrophilic non-porous polyurethane in a two-step manufacturing process of the fabric-coating layer to improve productivity, reduce environmental pollution and ensure excellent coating quality.

또한, 대한민국 등록특허 제0823630호 투습 및 발수성이 우수한 직물 및 그의 제조과정에서는 광경화형 불소계 발수발유제를 패딩처리한 후 스크린 메쉬를 이용하여 선택적 자외선 조사에 의한 투습발수직물을 제조하는 방법을 제안하였다.In addition, the Republic of Korea Patent No. 0831630 has excellent water vapor permeability and water-repellent fabric and a process of manufacturing the water-repellent water-repellent fabric by selective ultraviolet irradiation using a screen mesh after padding the photo-curing fluorine-based water and oil repellent was proposed. .

상기의 친수무공형 폴리우레탄을 이용한 건식코팅법은 환경오염 문제에서는 자유롭지만 세탁 내구성이 약한 단점을 지니고, 코팅 표면에 맺힌 물방울을 친수무공형 폴리우레탄이 흡수하여 팽윤현상을 일으키는 단점을 지니게 된다. 또한, 상기의 선택적 자외선 조사에 의한 투습방수직물 개발에 있어 스크린 메쉬를 올려놓은 후 바로 자외선 조사를 할 경우 스크린 메쉬의 격자부분이 미경화부분으로 존재하여 투습로를 형성시킴으로 내수압이 낮은 단점을 지니게 된다.
The dry coating method using the hydrophilic non-porous polyurethane has a disadvantage in that it is free from environmental pollution problems but weak in washing durability, and the hydrophilic non-porous polyurethane absorbs water droplets formed on the surface of the coating to cause swelling. In addition, in the development of the moisture-permeable waterproof fabric by the selective ultraviolet irradiation, when the UV irradiation immediately after placing the screen mesh, the lattice portion of the screen mesh is present as a non-hardened portion to form a moisture-permeable path has the disadvantage of low water pressure do.
