Description

투습방수포용 표면처리제 조성물 및 이를 이용한 투습방수포의 제조방법Surface treatment agent composition for moisture-permeable waterproof cloth and method for manufacturing moisture-permeable waterproof cloth using same

본 발명은 비이온성 아미노산인 천연양모의 미세분말을 함유하는 친수성 폴리우레탄계 표면처리제 및 이를 이용한 투습방수포의 제조방법에 관한 것이다.The present invention relates to a hydrophilic polyurethane-based surface treatment agent containing fine powder of natural wool, which is a nonionic amino acid, and a method for preparing a moisture-permeable waterproof fabric using the same.

최근 스포츠 웨어용 기능성 투습방수 원단은 내수압, 투습도등의 기본물성 수준 향상 뿐만 아니라 초쾌적성이나 감성적인 면도 상당히 중시하는 경향이 있다. 또한 에콜로지 차원에서 인체에 무해한 천연물질중 하나인 콜라겐을 사용하여 투습방수포를 제조하는 경우 습식 폴리우레탄 수지내에 2~3중량% 이내로 투입 혼합하여 분산시킨 후 디메틸포름아마이드(DMF) 농도 20% 이하의 습식 응고조내에서 응고, 수세, 건조하여 제조한 투습방수포는 쾌적성 증대, 천연의 느낌, 자연스런 촉감 등의 기능을 갖는 것으로 알려져 있다.Recently, the functional moisture-permeable waterproof fabric for sports wear tends to place a great emphasis on the level of basic physical properties such as water pressure and moisture permeability, as well as super comfortable or emotional shaving. In addition, in the case of manufacturing moisture-permeable foam using collagen, which is one of the harmless natural substances in terms of ecology, the mixture is dispersed within 2 to 3% by weight in a wet polyurethane resin, and then dispersed in a dimethylformamide (DMF) concentration of 20% or less. It is known that moisture-permeable blisters prepared by coagulation, rinsing and drying in a wet coagulation tank have functions of increasing comfort, feeling of nature, and natural touch.

그러나 위와같은 방법으로 제조시에는 소량의 콜라겐이 미세다공 필름내에 산재하므로 표면촉감의 개선효과가 콜라겐을 투입하지 않은 투습방수포에 비하여 크지 않고 믹싱시 수지내에서 콜라겐을 균일하게 분산시키는데 큰 어려움이 있다.However, when manufactured by the above method, since a small amount of collagen is scattered in the microporous film, the improvement in surface feel is not as large as that of the moisture-permeable waterproof bubble without collagen, and there is a great difficulty in uniformly dispersing collagen in the resin during mixing. .

그 외에도 콜라겐 처리에 의해 나타나는 효과중 하나인 결로방지, 흡수성 증대 등의 기능도 혼입방법으로 처리시 미세다공 필름층 표면에 양모분말의 입자가 소량만 돌출되므로 실질적으로 큰 효과를 기대하기는 곤란하다.In addition, it is difficult to expect a substantial effect because only a small amount of particles of wool powder protrude on the surface of the microporous film layer during the treatment by incorporating a function such as condensation prevention and absorption, which is one of the effects of collagen treatment. .

따라서 상기한 바와 같은 선행기술의 제반 문제점을 해소하기 위한 본 발명에 의하면, 메리노 양모 미세분말 3.8~7.0중량%, 친수무공형 폴리우레탄 수지 65~75중량%, 디메틸포름아마이드(DMF) 7.5~13중량%, 메틸에틸케톤(MEK) 7.5~13중량%, 경화제 1.5~2.5중량% 및 실리카 3.8~7.0중량%를 함유하는 것을 특징으로 하는 투습방수포용 표면처리제가 제공된다.Therefore, according to the present invention for solving the above problems of the prior art, merino wool fine powder 3.8-7.0% by weight, hydrophilic non-porous polyurethane resin 65-75% by weight, dimethylformamide (DMF) 7.5-13 There is provided a surface treating agent for moisture-permeable waterproof foam, which comprises by weight, methyl ethyl ketone (MEK) 7.5-13% by weight, curing agent 1.5-2.5% by weight, and silica 3.8-7.0% by weight.

본 조성물에 있어서, 메리노 양모 미세분말은 크기가 5~10μm인 것이 바람직하다.In this composition, it is preferable that the merino wool fine powder is 5-10 micrometers in size.

또한 본 조성물을 투습방수포에 표면처리하는 경우에는 통상의 표면처리수단이 사용될 수 있으나, 이들중에서도 특히 20~50메쉬의 엠보싱-롤이 바람직하다.In addition, when the present composition is surface-treated on the moisture-permeable waterproof cloth, conventional surface treatment means may be used, and among these, embossing rolls of 20 to 50 mesh are particularly preferable.

본 발명에 따르는 촉감 개선용 표면처리제 조성물로 처리한 투습방수포는 미처리 투습방수포나 콜라겐 혼입 투습방수포에 비하여 다음과 같은 특징이 있다.The moisture-permeable waterproof bubble treated with the surface treatment agent composition for improving the feel according to the present invention has the following characteristics as compared to the untreated moisture-resistant waterproof bubble or collagen-incorporated moisture-permeable bubble.

먼저 투습방수포 필름층 표면의 촉감이 일반적인 습식 투습방수포의 끈적거리는 촉감에서 표면층의 마찰계수가 낮아져 드라이(dry)하며 쾌적한 느낌의 터치로 바뀌고 미세다공층의 수분 흡방출성이 우수해져 결로방지가 되며 양모분말의 직접적인 영향으로 표면 열전도도 감소되어 따뜻한 느낌의 필름이 얻어질 수 있다. 또한 천연의 단백질 영향으로 천연의 질감이 자연스럽게 표출되는 초감성, 초쾌적 투습방수 코팅포를 얻을 수 있다. 그리고 표면처리제의 바인다로 사용된 친수무공형 수지의 작용으로 내수압 및 투습도가 향상되며 습식층의 미세다공을 세탁 및 드라이크리닝으로부터 보호할 수 있다.First, the touch of the surface of the moisture-permeable waterproof film layer is changed from the sticky touch of the general moisture-permeable waterproof cloth to the friction coefficient of the surface layer to change to a dry and pleasant touch, and to prevent condensation due to the excellent moisture absorption and release of the microporous layer. The direct effect of the wool powder also reduces the surface thermal conductivity can be obtained a film of a warm feeling. In addition, it is possible to obtain a super-sensitive, super-breathable moisture-proof coating fabric that naturally expresses the natural texture under the influence of natural protein. The hydrophilic non-porous resin used as the binder of the surface treatment agent improves the water pressure and moisture permeability, and protects the micropores of the wet layer from washing and dry cleaning.
