Description
본 발명은 방수성능과 투습성능이 우수한 투습방수 코팅직물의 제조방법에 관한 것으로, 보다 상세하게는 폴리우레탄 수지를 주로 하는 합성수지 중합체를 극성용매에 용해한 후 이용액을 이형재 원단의 편면에 도포하여 제조한 습식 멤브레인의 양쪽면에 직물, 편물 또는 부직포를 붙여 제조하는 마찰 저항성이 우수하고, 내수압, 투습도, 마모강도가 향상된 3층 구조 투습방수 코팅직물의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a moisture-permeable waterproof coating fabric having excellent waterproof performance and moisture permeability, and more particularly, by dissolving a synthetic resin mainly made of a polyurethane resin in a polar solvent and then applying the solution to one side of the release material fabric. The present invention relates to a method of manufacturing a three-layer water-permeable waterproof coating fabric having excellent frictional resistance by attaching a woven fabric, a knitted fabric or a nonwoven fabric to both sides of a wet membrane, and having improved water resistance, moisture permeability, and wear strength.
비나 눈과 같은 외부의 물은 통과시키지 않고 인체에서 발생하는 수증기는 통과할 수 있는 투습방수 직물은 그 유용한 성질로 인하여 스포츠웨어 분야에서 널리 사용되고 있는데, 이러한 투습방수 직물의 제조방법으로는 건식코팅법과 습식코팅법이 알려져 있다.Moisture-proof fabrics that can pass water vapor generated in the human body without passing outside water such as rain or snow are widely used in sportswear because of their useful properties. Wet coating methods are known.
건식코팅법은 포지 표면에 수지 코팅액으로 형성된 무공성 필름을 형성시키는 것으로, 내수압은 양호하나 습도가 떨어져 이를 향상시키기 위한 다양한 수지와 첨가제가 개발되고 있으나, 무공성 필름이므로 투습성은 제한적일 수 밖에 없다. 이에 비하여 습식코팅법은 유공성필름을 섬유위에 형성시키는 것으로 건식코팅법에 비해 투습도가 좋으나 습식코팅수지를 섬유위에 직접 도포하는 경우 통상 N,N-디포름아미드를 주용제로 사용하기 때문에 기포표면(코팅이면)에 수지가 부출되는 문제점이 있다. 이를 방지하기 위하여 코팅에 사용하는 기포를 고밀도화 하거나 발수가공 또는 칼렌더링 가공을 하고 있지만, 수지의 이와 같은 부출을 완전히 방지하기는 어렵고 이용가능한 기포가 한정되는 경우가 많다. 습식코팅 수지의 침투도를 조정하여 원단을 부드럽게하고 접착력을 향상시키기 위한 방법으로 습식코팅 이전에 원단 코팅면에 프라이머를 도포시키는 방법이 있으나, 이 경우 원단은 부드러워지나 투습성능과 방수성능이 크게 저하하는 문제가 발생한다. 또한, 사용한 코팅 포지의 요철이 심한 경우 예를 들면, 사용원사가 나일론 또는 폴리에스터 210데니어 이상인 에어 텍스쳐드 직물의 경우에는 칼렌더링 가공을 해도 평활성이 떨어져 두껍게 코팅할 수 밖에 없어 방수성능과 투습성능이 함께 우수한 코팅직물을 얻기가 매우 어렵다.Dry coating method is to form a non-porous film formed of a resin coating liquid on the surface of the forge, a good water resistance, but a variety of resins and additives have been developed to improve the fall off the humidity, but because of the non-porous film, the moisture permeability is limited. On the other hand, the wet coating method is to form a porous film on the fiber, which has better moisture permeability than the dry coating method. However, when the wet coating resin is directly applied onto the fiber, N, N-diformamide is usually used as the main solvent. Resin on the back side). In order to prevent this, the bubbles used in the coating are densified or water-repellent or calendered, but it is difficult to completely prevent such outflow of the resin and the available bubbles are often limited. As a method to soften the fabric and improve the adhesion by adjusting the penetration of the wet coating resin, there is a method of applying a primer on the coating surface before the wet coating, but in this case, the fabric is soft but the moisture permeability and waterproof performance are greatly reduced. A problem arises. In addition, when the unevenness of the used coated paper is severe, for example, in the case of air-textured fabric of which nylon or polyester is more than 210 denier, even if calendering is performed, the smoothness is inferior to the coating, resulting in a thick coating. With this, it is very difficult to get a good coating fabric.
상기와 같은 문제점을 해결하기 위하여 폴리아미노산 수지와 불소 함유 폴리우레탄 수지를 사용하여 우수한 투습, 방수기능을 갖는 습식 멤브레인을 제조하여 여러 가지 원단과 열라미네이션시켜 2층 구조의 투습성능과 방수성능이 함께 우수한 제품이 개발되었으나, 이러한 고기능 2층구조의 원단은 그 고기능이 요구되는 주요한 용도로서 일반 레져, 스포츠에 사용되기 보다는 고산과 같은 극심한 조건에서 인체활동이 많아 마찰에 의해 피막의 손상이 심하고 이에 따라 고기능이 저하하는 문제점이 있다.In order to solve the above problems, using a polyamino acid resin and a fluorine-containing polyurethane resin to manufacture a wet membrane having excellent moisture permeability and waterproofing function, it is heat-laminated with various fabrics, the moisture permeability and waterproof performance of the two-layer structure together Although excellent products have been developed, these highly functional two-layer fabrics are the main applications that require high performance, and are highly used in extreme conditions such as high mountains rather than in general leisure and sports. There is a problem that the high function is degraded.
본 발명의 목적은 종래 기술상의 문제점을 극복하여 투습성능과 방수성능이 우수하면서 외부의 물리적인 충격에 의해 기능저하가 적은 3층 구조의 부드러운 투습방수 코팅직물의 제조방법을 제공하는 것이다.SUMMARY OF THE INVENTION An object of the present invention is to provide a method of manufacturing a soft moisture-permeable waterproof coating fabric having a three-layer structure that overcomes the problems in the prior art and has excellent water-permeable performance and waterproof performance and is less functionally deteriorated by external physical impact.
즉, 본 발명은 폴리우레탄 수지를 주로 하는 합성수지 중합체를 극성 유기용매에 용해하여 내수성 이형재 원단에 도포한 후 응고시키고, 탈용매, 건조하여 습식멤브레인을 제조하고, 제조된 습식멤브레인을 원단과 접착시켜 이형재 원단을 박리한 후 이를 박지 편물 또는 부직포와 접착시키는 것을 특징으로 하는 3층 구조 투습방수 코팅직물의 제조방법에 관한 것이다.That is, the present invention is a synthetic resin polymer mainly made of polyurethane resin dissolved in a polar organic solvent, and applied to a water-resistant release material fabric, and then solidified, desolvent, dried to prepare a wet membrane, and the prepared wet membrane is bonded to the fabric The present invention relates to a method for manufacturing a three-layer water-permeable waterproof coating fabric which is characterized by peeling a release material fabric and then bonding it to a foil knitted fabric or a nonwoven fabric.
