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.
또한 종래의 투습방수포는 미세기공이 형성되어 있기 때문에 내수압이 3000mmH2O 이하이고, 투습도가 5000g/㎡·1일 이하이며, 촉감이 스티프하여 접힘소음이 심하고 드레이프(Drape)성이 나쁜 문제도 있었다.In addition, the conventional moisture-permeable waterproof cloth has a problem that the water pressure is 3000mmH 2 O or less, moisture permeability is 5000g / m 2 · 1 day or less because of the fine pores, the stiffness of the touch stiffness, severe folding noise and bad drape .
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 있다Conventional 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.
본 발명은 종래기술의 문제점들을 해결하므로서 환경오염이 없고 촉감, 내수압 및 투습성이 우수한 건식무공형 투습방수포를 제공하고자 한다.The present invention is to solve the problems of the prior art to provide a dry, non-porous moisture-proof waterproof bubble having no environmental pollution and excellent touch, water pressure and moisture permeability.
본 발명은 환경오염의 문제가 없고, 고기능성을 갖는 건식무공형 투습방수포에 관한 것이다.The present invention relates to a dry, non-porous moisture permeable blister having no problem of environmental pollution and having high functionality.
더욱 구체적으로 발수처리된 합성섬유의 직물 또는 편물상에 폴리비닐알코올 또는 폴리에틸렌옥사이드에서 유도된 친수성을 갖는 2액형 폴리우레탄 수지를 주성분으로 하는 베이스층이 형성되어 있고, 상기 베이스층 상에 친수성을 갖는 일액형 폴리우레탄 수지를 주성분으로 하며, 실리카를 함유하는 표면코팅층이 형성된 것을 특징으로 하는 건식무공형 투습방수포에 관한 것이다.More specifically, a base layer composed mainly of a two-component polyurethane resin having hydrophilicity derived from polyvinyl alcohol or polyethylene oxide is formed on a fabric or knitted fabric of water repellent treated synthetic fibers, and has hydrophilicity on the base layer.

이하 본 발명인 건식무공형 투습방수포의 제조방법을 상세히 설명한다.Hereinafter will be described in detail the manufacturing method of the present invention dry non-porous moisture-proof waterproof cloth.
먼저 폴리에스테르 및 폴리아미드 등의 합성섬유 직물 또는 편물을 테프론계 발수제로 발수처리한 다음 시레(Cire)가공하여 평활성을 부여한다. 이때 발수처리는 통상의 방법으로 실시하고, 시레가공은 130℃~150℃의 온도와 60kg/㎠ 정도의 압력하에서 실시하는 것이 바람직하다.First, synthetic fiber fabrics or knitted fabrics such as polyester and polyamide are subjected to a water repellent treatment with a Teflon-based water repellent and then subjected to Cire processing to give smoothness. At this time, the water-repellent treatment is carried out by a conventional method, and the shire processing is preferably carried out at a temperature of 130 ° C to 150 ° C and a pressure of about 60 kg / cm 2.
계속해서 발수처리된 합성섬유의 직물 또는 편물상에 아래 조성(I)와 같이 구성되어 폴리비닐알코올 또는 폴리에틸렌에서 유도된 친수성을 갖는 2액형 폴리우레탄 수지를 주성분으로 하는 조성물을 플로트 나이프 코팅방식으로 도포한 후 건조시켜 베이스층을 형성한다.Subsequently, on the fabric or knitted fabric of the water-repellent synthetic fiber, a composition consisting of a two-component polyurethane resin having a hydrophilicity derived from polyvinyl alcohol or polyethylene and having a main component as a main component is applied by a float knife coating method.

백색안료(이산화티타늄) 5~10중량%White pigment (titanium dioxide) 5 ~ 10 wt%
이때 사용되는 친수성의 2액형 폴리우레탄 수지는 점도가 300~400포아즈인 것이 바람직하다. 제 1코팅층 형성시 코팅량은 100~200g/㎡인 것이 바람직하며, 건조는 100~140℃에서 0.5~2분정도 실시하는 것이 바람직 하다.It is preferable that the hydrophilic two-component polyurethane resin used at this time is 300-400 poise of viscosity. When forming the first coating layer, the coating amount is preferably 100 to 200 g / m 2, and drying is preferably performed at 100 to 140 ° C. for about 0.5 to 2 minutes.
2액형 폴리우레탄 수지는 말단에 -OH를 갖는 우레탄 수지와 말단 이소시아네이트계 가교제를 결합한 것으로 강신도가 우수한 피막제조가 가능하다. 2액형 수지의 물성은 수지와 촉매의 조성량, 큐어링조건, 숙성조건 등에 따라 변한다.The two-component polyurethane resin combines a urethane resin having -OH at the terminal and a terminal isocyanate-based crosslinking agent, thereby making it possible to produce a film having excellent elongation. The physical properties of the two-component resin vary depending on the composition of the resin and the catalyst, curing conditions, aging conditions, and the like.
다음으로는 상기 베이스층 상에 아래 조성(Ⅱ)와 같이 구성되어 친수성을 갖는 일액형 폴리우레탄 수지를 주성분으로 하고, 실리카를 함유하는 수지 조성물을 플로트 나이프 코팅방식으로 도포한 후 건조시켜 표면코팅층을 형성시킨다.Next, a one-component polyurethane resin having a hydrophilic property as a main component is formed on the base layer as shown in the following composition (II), and a resin composition containing silica is applied by a float knife coating method and dried to form a surface coating layer. To form.
- 조성(Ⅱ) --Composition (Ⅱ)-
친수성을 갖는 일액형 폴리우레탄 수지(고형분 30%, 물 70%) 64~82중량%One-component polyurethane resin having hydrophilicity (solid content 30%, water 70%) 64 to 82% by weight

실리카(SiO2) 5~10중량%Silica (SiO 2 ) 5 ~ 10 wt%
백색안료 3~ 6중량%White pigment 3 ~ 6 wt%
이때 사용되는 친수성의 일액형 폴리우레탄 수지는 점도가 70~150포아즈 인것이 바람직하다. 표면코팅층 형성시 건조는 120~160℃에서 0.5~2분정도 실시하는 것이 바람직하다. 조성(Ⅱ)에 함유되는 실리카의 평균입자 크기는 3~4㎛,함유량은 10중량% 정도인 것이 적절하다.The hydrophilic one-component polyurethane resin used at this time is preferably a viscosity of 70 ~ 150 poise. When the surface coating layer is formed, the drying is preferably performed at 120 to 160 ° C. for about 0.5 to 2 minutes. It is appropriate that the average particle size of silica contained in the composition (II) is 3 to 4 µm and the content is about 10% by weight.
일액형 폴리우레탄 수지는 용제를 제거하는 중에 강인한 피막이 형성되며, 직쇄상 분자구조를 갖는다. 또한 결정부(우레탄 결합)와 비결정부(장쇄의 폴리올)로 구성되어 있으며 결정부는 우레탄 결합간에 수소결합을 이루고 있어서 이부분을 용해시키기 위해서는 극성이 강한 용제가 필요하다. 일액형 우레탄 수지의 경연도는 결정성의 정도에 의해 결정되며, 완전한 결정화에는 3~7일이 소요된다.The one-component polyurethane resin has a strong film formed while removing the solvent, and has a linear molecular structure. It is composed of a crystal part (urethane bond) and an amorphous part (long chain polyol), and the crystal part forms a hydrogen bond between the urethane bonds, and a polar solvent is required to dissolve this part. The hardness of the one-component urethane resin is determined by the degree of crystallinity, and complete crystallization takes 3 to 7 days.
상기 베이스 층 및 표면코팅층은 한번의 코팅으로 1층으로 형성시킬 수도 있고, 2회 이상의 코팅으로 2층 이상으로 형성시킬 수도 있으나, 평활성 유지를 위해서는 1층으로 형성시키는 것이 가장 바람직하다.The base layer and the surface coating layer may be formed in one layer by one coating, or may be formed in two or more layers by two or more coatings, but in order to maintain smoothness, it is most preferable to form one layer.
베이스층만을 형성시키는 경우라도 층내에 존재하는 초미세간격을 통하여 습기가 확산되는 원리에 의해 투습능을 보유하고 미세공이 없어 내구성도 우수하지만, 친수성 수지의 특성상 표면 끈적임이 심하여 봉제시 슬립성이 저하되고 권취시 블로킹되는 문제가 있다.Even when only the base layer is formed, it retains moisture permeability due to the principle of diffusion of moisture through the ultra-fine intervals present in the layer and has excellent durability because there are no micropores. And blocking when winding up.
따라서 본 발명은 이러한 문제점을 개선하기 위하여 상기 베이스층 위에 조성(Ⅱ)와 같은 코팅수지조성물로 표면코팅층을 형성시키는 것을 특징으로 한다. 상기 표면코팅층은 내구성 및 내수압을 증대시키는 역할도 한다.Therefore, the present invention is characterized by forming a surface coating layer with a coating resin composition such as composition (II) on the base layer to improve this problem. The surface coating layer also serves to increase durability and water pressure.
