Description
본 발명은 환경오염 없이도 촉감, 내수압 및 투습도 등이 우수한 건식무공형 투습방수포의 제조방법에 관한 것이다.The present invention relates to a method for producing a dry, non-porous moisture-proof waterproof cloth excellent in touch, water pressure and moisture permeability without environmental pollution.
투습방수포는 스포츠웨어, 등산복 및 스키웨어 등과 같이 비교적 가혹한 기상조건 하에서 격렬한 운동을 할 때 착용하는 스포츠용 의류 원단으로 사용 되고 있다.Moisture-proof tarpaulin is used as a sports apparel fabric to be worn during intense exercise under relatively severe weather conditions such as sportswear, mountaineering clothes and skiwear.
종래 투습방수포는 원단상에 유기용제에 용해 될수 있는 습식 폴리우레탄 수지(분자량 15만~20만)조성물 또는 폴리우레탄 수지(분자량 7만~10만)조성물을 플로팅 나이프(Floating Knife) 또는 나이프 오버 롤(Knife Over Roll) 방식으로 직접 도포한 다음 건식 또는 습식공정으로 응고시켜 코팅층 상에 미세기공을 형성하는 방법으로 제조되어 왔다.Conventional breathable tarpaulin is a floating knife or knife overroll for the composition of a wet polyurethane resin (molecular weight 150,000 to 200,000) or a polyurethane resin (molecular weight 70,000 to 100,000) that can be dissolved in an organic solvent on the fabric. (Knife Over Roll) has been manufactured by a method of directly applying the method followed by solidification in a dry or wet process to form micropores on the coating layer.
이와 같은 종래의 투습방수포는 인체에 유해하고 수질 및 대기 공해를 유발하는 디메틸포름아마이드, 메틸에틸케톤, 톨루엔 등의 유기용제를 다량 사용하여 제조함으로 인해 가공 공장의 작업환경을 저해하고 환경오염을 초래하는 원인이 되어왔다.Such a conventional moisture-permeable foam is produced by using a large amount of organic solvents, such as dimethylformamide, methyl ethyl ketone, and toluene, which are harmful to the human body and cause water and air pollution. It has been a cause.
최근 이런 문제점들을 해결하기 위하여 폴리에스테르, 폴리아미드 또는 이들의 혼섬 포지상에 수분산형 발수제를 함유하는 유중수분산형(이하 w/o형 이라고 한다) 에멀젼 폴리우레탄 수지코팅액, 저분자형 수용성 아크릴수지 코팅액 또는 수용성폴리우레탄수지 코팅액 등을 나이프 오버 롤(Knife Over Roll) 방식으로 코팅한 후 다단 건조하여 건식다공형 투습방수포를 제조하였다.In order to solve these problems in recent years, water-in-oil-dispersion type (hereinafter referred to as w / o type) emulsions containing water-dispersible water repellents on polyester, polyamide, or intermixture thereof, polyurethane resin coating liquid, low molecular weight water-soluble acrylic resin coating liquid or A water-soluble polyurethane resin coating solution and the like was coated in a knife over roll method, and then dried in multiple stages to manufacture a dry porous moisture-permeable waterproof fabric.
상기 방법으로 제조된 종래의 건식다공형 투습방수포는 환경오염의 문제를 해결 할수 있지만, 내수압 및 투습도 등의 기능성이 저하되는 문제가 있다.Conventional dry porous permeable waterproof fabric prepared by the above method can solve the problem of environmental pollution, but there is a problem that the functionality such as water pressure and moisture permeability is lowered.
한편, 상기와 같은 문제점들을 해결하기 위하여 발수처리된 합성섬유의 직물상에 친수성 폴리우레탄 수지조성물(유기용제 사용안함)을 도포, 건조하여 건식무공형 투습방수포를 제조하는 방법도 실시되고 있다.On the other hand, in order to solve the above problems, a method of manufacturing a dry, non-porous moisture-proof waterproof fabric by applying and drying a hydrophilic polyurethane resin composition (no organic solvent) on the fabric of the water-repellent synthetic fibers.
그러나, 상기 방법으로 제조된 건식무공형 투습방수포는 환경오염이 없고 내수압 및 투습성도 우수하나 친수성 폴리우레탄 수지의 특성상 표면 끈적임이 심하여 봉제시 슬립성이 저하되고 권취성도 나빠지는 문제가 있고, 표면광택이 심하여 코팅면이 고급스러운 느낌을 주지 못하는 단점이 있었다.However, the dry non-porous moisture-proof waterproof fabric prepared by the above method has no environmental pollution, and has excellent water pressure and moisture permeability, but due to the characteristics of the hydrophilic polyurethane resin, surface stickiness is severe, resulting in poor slipperiness and poor windability when sewing, and surface gloss. This was bad because the coating surface did not give a luxurious feel.
상기의 건식무공형 투습방수포의 문제점을 해결하기 위한 또다른 종래 기술로서 합성섬유 직물상에 친수성 폴리우레탄 수지조성물을 코팅하여 베이스층을 형성시킨 다음, 상기 베이스층 위에 다시 수용성/음이온성 폴리우레탄 수지조성물을 코팅하여 표면코팅층을 형성하여 건식무공형 투습방수포를 제조하는 방법도 제안된바 있다.As another conventional technique for solving the above problems of the dry, non-porous moisture-proof waterproof fabric, a hydrophilic polyurethane resin composition is coated on a synthetic fiber fabric to form a base layer, and then the water-soluble / anionic polyurethane resin is again formed on the base layer. The method of coating a composition to form a surface coating layer to produce a dry non-porous moisture-proof waterproof fabric has also been proposed.
그러나, 상기 방법은 건식무공형 투습방수포의 표면 끈적임 현상은 방지할 수 있으나, 2단계의 코팅공정을 거쳐야 하므로 공정이 복잡한 문제가 있었다.However, the above method can prevent the surface stickiness of the dry, non-porous moisture-proof waterproof fabric, but the process has a complicated problem because it must go through a two-step coating process.
본 발명은 종래기술의 문제점들을 해결하므로서 환경오염이 없고 촉감, 내수압 및 투습성이 우수한 건식무공형 투습방수포를 보다 간편한 공정으로 제조하는 방법을 제공하고자 한다. The present invention is to solve the problems of the prior art to provide a method of manufacturing a dry, non-porous moisture-proof waterproof foam excellent in the touch, water pressure and moisture permeability and more convenient process.
이와같은 과제를 달성하기 위한 본 발명의 건식무공형 투습방수포의 제조방법은, 이형지상에 아래 조성(Ⅰ)의 폴리우레탄 수지조성물을 플로트 나이프 코팅방식으로 도포후 건조하여 건식무공형 필름을 제조한 다음, 상기 건식무공형 필름을 합성섬유 직물상에 라미네이팅 시킨 후 이형지를 박리하는 것을 특징으로 한다.In order to achieve the above object, a method of manufacturing a dry non-porous moisture-proof waterproof fabric of the present invention is to apply a polyurethane resin composition of the following composition (I) to a release paper by a float knife coating method and then dry to produce a dry non-porous film. Next, the dry non-porous film is characterized in that the release paper is peeled off after laminating on a synthetic fiber fabric.

이하, 본 발명을 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.
먼저, 이형지상에 상기 조성(Ⅰ)의 폴리우레탄 수지 조성물을 플로트 나이프 코팅 방식으로 도포 후 건조하여 이형지 상에 건식다공형 폴리우레탄 필름을 제조한다.First, the polyurethane resin composition of the composition (I) is applied to a release paper by a float knife coating method and dried to prepare a dry porous polyurethane film on the release paper.
이때, 상기 폴리우레탄 수지조성물의 도포량은 25~35g/㎡인 것이 좋다. 상기 도포량이 25g/㎡ 미만인 경우에는 충분한 투습성과 내수압을 발현하기 어렵고, 35g/㎡을 초과하는 경우에는 촉감이 저하된다.At this time, the coating amount of the polyurethane resin composition is preferably 25 ~ 35g / ㎡. When the said coating amount is less than 25 g / m <2>, it is difficult to express sufficient moisture permeability and water pressure, and when it exceeds 35 g / m <2>, a touch will fall.
상기 친수성/수용성 폴리우레탄 수지는 Ph가 7~8이고 점도가 250포아즈인 것이 바람직하고, 건조는 100~150℃에서 1~5분 정도 실시한다.It is preferable that Ph is 7-8 and viscosity is 250 poise, and the said hydrophilic / water-soluble polyurethane resin carries out drying for about 1 to 5 minutes at 100-150 degreeC.
한편 상기의 수용성/음이온성 수지로는 폴리올과 지방족 이소시아네이트를 반응시켜 제조한 것을 사용한다.On the other hand, as the water-soluble / anionic resin, those prepared by reacting polyols with aliphatic isocyanates are used.
수용성 원료 물질로는 설포네이트 타입과 카복실레이트 타입의 음이온성 수지 등을 사용한다.As the water-soluble raw material, an anionic resin of sulfonate type and carboxylate type is used.
한편으로는, 폴리에스테르 및 폴리아미드 등의 합성섬유 직물을 테프론계 발수제로 발수처리한 다음 시레(cire)가공하여 평활성을 부여한다.On the other hand, synthetic fiber fabrics such as polyester and polyamide are water repelled with a Teflon-based water repellent and then processed into cire to impart flatness.
이때 발수처리는 통상의 방법으로 실시하고 시레가공은 130~150℃의 온도에서 60㎏/㎠의 압력으로 실시하는 것이 바람직하다.At this time, the water-repellent treatment is carried out by a conventional method and the shire processing is preferably carried out at a pressure of 60 kg / ㎠ at a temperature of 130 ~ 150 ℃.
다음으로는, 상기와 같이 발수처리 및 시레가공된 함성섬유 직물상에 상기의 건식다공형 필름을 라미네이팅 한 후 이형지를 박리하여 최종 제품인 건식무공형 투습방수포가 제조된다.Next, after laminating the above-mentioned dry porous film on the water-repellent and shire-processed synthetic fiber fabric as described above, the release paper is peeled off to produce a dry, non-porous moisture-proof waterproof fabric as a final product.
본 발명에 따라 제조된 건식무공형 투습방수포는 내수압 3,000~5,000mH20, 투습도 6,000~9,000g/㎡·24시간(ASTM 96-95 B법)이며, 촉감이 매우 우수하다.The dry, non-porous moisture-proof waterproof fabric prepared in accordance with the present invention has a water pressure of 3,000 to 5,000 mH 2 0, a moisture permeability of 6,000 to 9,000 g / m 2 · 24 hours (ASTM 96-95 B method), and is excellent in touch.
이하 실시예 및 비교실시예를 통하여 본 발명을 더욱 상세하게 살펴본다. 그러나 본 발명이 아래 실시예에만 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. However, the present invention is not limited only to the following examples.
