투습방수 직물의 제조에 관한 종래 기술로써, 습식응고 폴리우레탄막을 포백표면에 보유하는 고내수압 고투습성 방수시이트에 관한 대한민국등록특허 제10-0295274호 "고내수압고투습성 방수시이트 및 그 제조방법", 투습성을 향상시키기 위해 염화나트륨을 분산시킨 폴리우레탄을 이용하여 건식코팅하고, 따뜻한 물로 무기염을 녹여내서 미세한 기공을 형성시켜 내수압과 투습도 양쪽 모두를 향상시킨 투습방수 직물의 제조에 관한 대한민국등록특허 제10-0478129호 "투습방수 직물의 제조방법"이 있으나, 단일층의 투습 방수직물에 관한 것이고, 그 외에도 대한민국등록특허 제10-0103957호 "투습성방수포 및 그 제조방법", 대한민국등록특허 제10-0067967호 "투습성방수시이트물질및그제조방법", 대한민국등록특허 제10-0034454호 "보온성및내구성이우수한투습방수포의제조방법", 대한민국등록특허 제10-0025059호 "투습성방수포의제조방법" 및 대한민국등록특허 제10-0023785호 "투습성방수포의제조방법" 등 당해 기술분야에서 다수의 등록특허가 존재하지만, 이중 복합 투습 방수직물에 제조에 관한 연구는 활발하지 않았다. As a conventional technique for manufacturing a moisture-permeable waterproof fabric, Korean Patent No. 10-0295274 "Highly water-resistant high-moisture-permeable waterproof sheet and its manufacturing method" for a high-water pressure-high moisture-permeable waterproof sheet having a wet coagulated polyurethane film on the fabric surface. In order to improve moisture permeability, dry coating was performed using polyurethane dispersed with sodium chloride, and the inorganic salts were dissolved in warm water to form fine pores, thereby improving moisture resistance and moisture permeability. -0478129 "Method of manufacturing moisture-permeable waterproof fabric", but relates to a single-layer water-permeable waterproof fabric, in addition to the Republic of Korea Patent No. 10-0103957 "Water-permeable waterproof fabric and its manufacturing method", Republic of Korea Patent No. 10-0067967 No. "Water-permeable waterproof sheet material and its manufacturing method", Republic of Korea Patent No. 10-0034454 "Excellent moisture-proofing and moisture resistance There are a number of registered patents in the art such as fabrication method of fabric ", Korean Patent No. 10-0025059," Method for manufacturing breathable waterproof fabric, "and Korean Patent No. 10-0023785," Method for manufacturing breathable waterproof fabric. " There is little research on the manufacture of composite breathable waterproof fabrics.
또한, 폴리우레탄을 소재로 한 투습 방수 직물을 제조하는 종래의 기술로는 폴리우레탄과 유기용제인 디메틸포름아마이드를 혼합하여 제조한 수지를 직물 상에 일정한 두께로 도포한 후 물속에서 응고시키는 과정에서 발생하는 연속적인 미세한 기공을 갖는 폴리우레탄 필름층이 투습성 및 내수압을 동시에 갖도록 하는 습식공 법이 있다.In addition, a conventional technique for manufacturing a moisture-permeable waterproof fabric made of polyurethane is a resin prepared by mixing a polyurethane and an organic solvent dimethylformamide in a process of solidifying in water after applying a predetermined thickness on the fabric There is a wet method in which a polyurethane film layer having continuous fine pores generated simultaneously has moisture permeability and water pressure resistance.
또한, 친수성의 폴리우레탄을 휘발성 있는 디메틸포름아마이드, 메텔에텔케톤, 톨루엔, 아세톤, 이소프로필 알코올 등의 유기용제에 용해시켜 제조한 친수성 폴리우레탄 수지를 직물 상에 일정한 두께로 코팅한 후 건조 챔버에서 가열하여 휘발성이 있는 유기용제를 휘발시킴으로써 직물 위에 균일한 폴리우레탄 필름층을 형성시켜서 투습성 및 내수압을 갖도록 하는 건식공법이 있다.In addition, a hydrophilic polyurethane resin prepared by dissolving a hydrophilic polyurethane in an organic solvent such as volatile dimethylformamide, metel ether ketone, toluene, acetone, isopropyl alcohol, etc. is coated on a fabric to a predetermined thickness and then dried in a drying chamber. There is a dry method of heating a volatilized organic solvent to form a uniform polyurethane film layer on the fabric to have moisture permeability and water pressure.
상기 건식공법에는 용액형 친수성 폴리우레탄을 직물 위에 직접도포하여 건조 챔버에서 용제를 건조하는 직접도포 방식과 이형지위에 일정 두께로 코팅한 다음 건조 챔버에서 유기용제를 휘발시켜 필름을 형성한 후 용제형 접착제나 무용제형 반응성 핫멜트 접착제로 직물을 합포하는 전사도포 방식으로 크게 나눌 수 있다. In the dry method, a solution-type hydrophilic polyurethane is directly coated onto a fabric, and a direct coating method of drying a solvent in a drying chamber and a coating film having a predetermined thickness on a release paper, followed by volatilization of an organic solvent in a drying chamber to form a film, and then a solvent-type adhesive. The solvent-free reactive hot melt adhesive can be broadly classified into a transfer coating method in which a fabric is combined.
이와 같은 종래의 투습 방수직물 제조 방법 중에서 습식법은 소수성의 미세한 연속적인 기공 형성으로 표면에 물방울에 의한 팽윤현상이 없고, 보온성이 양호하며, 투습도가 우수한 장점이 있으나 세탁 후나 반복 착용으로 인한 내수압 저하 등 내수압의 내구성은 좋지못한 단점이 있다. 또한, 친수성의 폴리우레탄을 이용하여 건식법으로 제조한 투습방수 직물은 표면에 맺힌 물방울의 수분을 흡수하여 팽윤현상이 발생하므로 외관상 좋지않고, 휘발성 유기용제가 휘발하는 과정에서 형성되는 미세한 기포에 의한 내수압 저하 등의 내구성 면에서 문제가 있었다. In the conventional method of manufacturing a waterproof moisture-permeable fabric, the wet method has hydrophobic fine continuous pores, and there is no swelling phenomenon due to water droplets on the surface, and it has good thermal insulation and excellent moisture permeability, but the water resistance decreases after washing or repeated wearing. The durability of water pressure has a disadvantage. In addition, the moisture-permeable waterproof fabric manufactured by the dry method using a hydrophilic polyurethane is not good in appearance because it swells by absorbing the moisture of the water droplets formed on the surface, and the water pressure due to the fine bubbles formed during the volatilization of the volatile organic solvent There was a problem in terms of durability such as degradation.
상기와 같이 수증기상의 물분자를 이동시키기 위한 방법으로 고안된 미세다공질 폴리우레탄이나 친수성 폴리우레탄은 각각의 장단점을 가지고 있어 상기 단점 을 해결할 새로운 기술 개발이 요구되고 있으며, 최근에는 습식코팅층 표면에 용액형의 친수성 폴리우레탄을 나이프로 도포하거나 그라비아를 사용하여 도포하는 방안이 시도되고 있으나 그 기술개발이 미흡한 실정이었다.As described above, microporous polyurethanes or hydrophilic polyurethanes, which are designed as methods for moving water molecules on water vapor, have respective advantages and disadvantages, and thus, new technologies need to be developed to solve the above disadvantages. A method of applying a hydrophilic polyurethane with a knife or using gravure has been attempted, but the technology development has been insufficient.
특히, 직접 입수하거나 수압을 받은 환경에서 사용하는 낚시복의 경우, 기존 직물을 이용해 제조한 낚시복은 반복적으로 3∼4회정도 사용하면 물이 스미거나 내수압이 저하되어 제품 물성상 문제가 발생하는 일이 빈번하여, 내수압의 내구성이 향상된 직물의 개발이 절실하였다. In particular, in the case of fishing clothes that are directly obtained or used in a pressure-reduced environment, fishing clothes manufactured using existing fabrics may have problems with product properties due to water smearing or reduced water pressure when used repeatedly three to four times. Frequently, the development of fabrics with improved water resistance durability is urgent.
이에 본 발명자들은 폴리우레탄 소재를 사용한 투습방수직물 제조에 있어서 습식법의 장점과 건식법의 장점을 모두 갖춘 투습 방수직물 제조방법을 개발하고자 예의 노력한 결과, 일정 두께의 친수성 무공 투습 필름을 미세 다공형의 습식코팅층이 도포된 직물과 점 도포방식 또는 전면 도포방식으로 합포하여 내수압이 우수한 투습방수 직물을 제조할 수 있다는 것을 확인하고, 본 발명을 완성하였다. Accordingly, the present inventors have diligently tried to develop a method for manufacturing a moisture-permeable waterproof fabric having both the advantages of the wet method and the dry method in manufacturing a moisture-permeable waterproof fabric using a polyurethane material. The present invention was completed by confirming that the fabric coated with the coating layer and the spot coating method or the front coating method were able to produce a moisture-permeable waterproof fabric having excellent water pressure.
결국, 본 발명의 주된 목적은 폴리우레탄 소재를 사용한 종래의 투습방수직물 제조에 있어서 습식법 및 건식법의 장점을 모두 갖추도록 미세 다공형인 습식층과 균일한 두께를 가진 친수성 무공형 투습 필름을 합포하여 미세 다공층과 무공형 필름의 이중복합 구조를 형성하여 내수압이 우수한 투습방수 직물의 제조방법을 제공하는 데 있다.After all, the main object of the present invention is to combine the microporous wet layer and the hydrophilic non-porous moisture-permeable film having a uniform thickness so as to have all the advantages of the wet method and the dry method in manufacturing a conventional moisture-permeable fabric using a polyurethane material.
