4. 발명의 중요한 용도4. Important uses of the invention
본 발명의 건식다공형 투습 방수포는 주로 스포츠웨어용 원단으로 사용된다.Dry porous breathable tarpaulin of the present invention is mainly used as a fabric for sportswear.
Description
본 발명은 내수압 및 투습도가 우수한 건식다공형 투습 방수포 및 그의 제조 방법에 관한 것이다. 건식다공형 투습 방수 원단은 스포츠 웨어, 등산복 및 스키웨어 등과 같이 비교적 가혹한 기상조건하에서 격렬한 운동을 할 때 착용하는 의류용 원단으로 사용되고 있다.The present invention relates to a dry porous moisture permeable tarp excellent in water pressure and moisture permeability and a method of manufacturing the same. Dry porous permeable waterproof fabric is used as a fabric for clothing worn during intense exercise under relatively harsh weather conditions such as sports wear, mountaineering clothes and ski wear.
따라서, 건식다공형 투습 방수 원단에는 강우시 빗방울을 차단함은 물론 저온 환경에서는 의복내 체온을 유지시켜 주고, 격렬한 운동에 따른 고온 환경에서는 몸으로부터 발한된 땀을 방출하여 의복내 온도를 일정하게 유지시켜 줌으로서 항상 쾌적한 착용감을 발현할 수 있는 고내수압과 고투습도의 기능이 요구되고 있다.Therefore, the dry porous breathable waterproof fabric not only blocks raindrops during rainfall, but also maintains body temperature in clothes in low temperature environments, and maintains the temperature in clothes by releasing sweat from the body in high temperature environments following intense exercise. As a result, high water pressure and high moisture permeability, which can always express a comfortable fit, are required.
이와 같은 건식다공형 투습 방수포를 제조하는 종래 기술로서는 폴리에스테르, 폴리아미드 또는 이들의 혼섬 포지상에 아래 조성과 같이 수분산형 발수제를 함유하는 유중 수분산형(이하 w/o형이라고 한다) 에멀젼 폴리우레탄 수지 코팅액을 나이프 오버롤(Knife Over Roll) 방식으로 코팅한 후 다단 건조하여 건식다공형 투습 방수포를 제조하였다.As a conventional technique for producing such a dry porous moisture permeable tarpaulin, a water-in-oil type emulsion (hereinafter referred to as w / o type) emulsion polyurethane containing polyester, polyamide or a water-dispersible water repellent agent as shown below on a mixed fiber thereof The resin coating solution was coated in a knife over roll method, and then dried in multiple steps to prepare a dry porous permeable tarp.
이때 사용된 w/o형 에멀젼 폴리우레탄 수지 코팅액의 조성은 아래 조성 Ⅰ 과 같다.The composition of the w / o type emulsion polyurethane resin coating liquid used at this time is the same as the composition I below.
- 조 성 Ⅰ --Composition Ⅰ-
폴리우레탄 수지100 중량부100 parts by weight of polyurethane resin
유기용제(메틸에틸케톤/톨루엔)20~50 중량부(10~30 중량부 / 10~20 중량부)20-50 parts by weight of organic solvent (methyl ethyl ketone / toluene) (10-30 parts by weight / 10-20 parts by weight)
경화제(헥사메틸렌 디이소시아네이트)1~5 중량부1 to 5 parts by weight of curing agent (hexamethylene diisocyanate)
수분산형 발수제(플루오로 카본 고형분 30 중량%)1~5 중량부Water dispersion type water repellent (fluorocarbon solid content 30% by weight) 1-5 parts by weight
물/메틸에틸케톤 혼합용액31~70 중량부(30~60 중량부 / 1~10 중량부)Water / methyl ethyl ketone solution 31 ~ 70 parts by weight (30 ~ 60 parts by weight / 1 ~ 10 parts by weight)
종래 기술에 있어서 상기 코팅액의 코팅 두께는 20~40㎛이며, 코팅후 다단 건조 조건은 80℃에서 30초~1분 정도 1단 건조하고, 120℃에서 30초~1분 정도 2단 건조한 후 150℃에서 30초~1분 정도 3단 건조하여 건식 다공형 투습 방수포를 제조한다.In the prior art, the coating thickness of the coating solution is 20 to 40㎛, after the multi-stage drying conditions, the coating is dried in one stage at 80 ° C for 30 seconds to 1 minute, and dried at 120 ° C for 30 seconds to 1 minute in two stages of 150 Three stages of drying for 30 seconds to 1 minute at ℃ ℃ to prepare a dry porous breathable tarpaulin.
이와 같은 종래 기술에서는 건식다공형 투습 방수포의 내수압을 향상시킬 목적으로 수분산형 발수제를 사용하기 때문에 상기 발수제는 제 1 도와 같이 w/o형 에멀젼에서 유중에 분산된 물입자와 혼합되어 공존하게 된다. 따라서 코팅후 건조 공정에서 유기용제가 먼저 기화된 후 계속해서 물이 수증기 상태로 증발하게 되면 상기 발수제는 미세한 기공 주변에 집중적으로 존재하게 된다. 그 결과 상기 발수제는 상대적으로 밀도가 높은 폴리우레탄 필름 전체에 골고루 분산되지 않아 필름 전체의 소수화가 곤란하게 된다. 이와 같은 원인으로 종래 기술에 의해 제조된 건식다공형 투습 방수포의 내수압은 1,500~2,500 ㎜ H2O 수준에 불과하다.In the prior art, since a water-dispersible water repellent is used for the purpose of improving the water pressure of the dry porous moisture permeable tarpaulin, the water repellent is coexisted with water particles dispersed in oil in a w / o emulsion as in the first degree. Therefore, when the organic solvent is first vaporized in the drying process after coating and water is continuously evaporated in the water vapor state, the water repellent is concentrated around the fine pores. As a result, the water repellent is not evenly dispersed throughout the relatively high density polyurethane film, making it difficult to hydrophobize the entire film. For this reason, the water pressure of the dry porous moisture permeable tarp manufactured by the prior art is only 1,500-2,500 mm H 2 O level.
그러나 최근에는 고투습성과 동시에 고내수압을 갖는 투습 방수포의 요구가 증가함에 따라 이와 같은 종래 기술의 문제점을 해결할 수 있는 새로운 기술 개발이 요구되고 있다.However, in recent years, as the demand for a moisture-permeable tarpaulin having high moisture permeability and high water resistance increases, there is a demand for developing a new technology that can solve the problems of the prior art.
본 발명은 이상에서 설명한 종래 기술의 문제점을 해결하므로서 고투습도와 동시에 고내수압의 물성을 갖는 건식다공형 투습 방수포 및 그의 제조방법을 제공하고자 한다.The present invention is to provide a dry porous permeable waterproof tarpaulin having a high moisture permeability and at the same time high water resistance properties while solving the problems of the prior art described above and a method of manufacturing the same.

본 발명은 고투습도와 동시에 고내수압을 갖는 건식다공형 투습 방수포 및 그의 제조 방법에 관한 것이다.The present invention relates to a dry porous vapor permeable tarpaulin having a high moisture permeability and at the same time a high water pressure resistance, and a manufacturing method thereof.
더욱 구체적으로 본 발명은 유기용제 분산형 발수제를 함유하는 유중 수분산(w/o)형 에멀젼 폴리우레탄 수지 코팅액으로 코팅되어 내수압(JIS-L 1096 방법으로 측정)이 3,000 ㎜ H2O 이상이고, 투습도(JIS-L 1099 방법으로 측정)가 5,000g/㎡·24시간 이상인 건식다공형 투습 방수포에 관한 것이다.More specifically, the present invention is coated with an aqueous dispersion of water-in-oil (w / o) emulsion polyurethane resin coating liquid containing an organic solvent-dispersed water repellent so that the water pressure (measured by JIS-L 1096 method) is 3,000 mm H 2 O or more, A moisture permeability (measured by JIS-L 1099 method) relates to a dry porous moisture permeable tarpaulin having 5,000 g / m 2 · 24 hours or more.
또한 본 발명은 폴리우레탄계 수지, 유기용제, 경화제 및 발수제를 필수적으로 함유하는 유중 수분산(w/o)형 에멀젼 폴리우레탄 수지 코팅액으로 섬유포지를 코팅하여 건식다공형 투습 방수포를 제조함에 있어서, 발수제로서 유기용제 분산형 발수제를 사용하는 것을 특징으로 하는 건식다공형 투습 방수포의 제조 방법에 관한 것이다.In addition, the present invention is a water-repellent agent in manufacturing a dry porous moisture-permeable tarpaulin by coating the fiber cloth with a water-in-oil (w / o) emulsion polyurethane resin coating liquid containing essentially a polyurethane-based resin, an organic solvent, a curing agent and a water repellent agent. The present invention relates to a method for producing a dry porous permeable tarpaulin, characterized in that an organic solvent dispersed water repellent is used.
본 발명을 더욱 상세하게 설명하기로 한다.The present invention will be described in more detail.
먼저 섬유포지 상에 코팅되는 유중 수분산(w/o)형 에멀젼 폴리우레탄 수지 코팅액의 조성은 아래 조성 (Ⅱ) 와 같다.First, the composition of the water-in-oil (w / o) emulsion polyurethane resin coating liquid coated on the fiber cloth is shown in the following composition (II).
- 조 성 Ⅱ --Composition Ⅱ-
폴리우레탄 수지100 중량부100 parts by weight of polyurethane resin
유기용제(메틸에틸케톤/톨루엔)20~50 중량부(10~30 중량부 / 10~20 중량부)20-50 parts by weight of organic solvent (methyl ethyl ketone / toluene) (10-30 parts by weight / 10-20 parts by weight)
경화제(헥사메틸렌 디이소시아네이트)1~5 중량부1 to 5 parts by weight of curing agent (hexamethylene diisocyanate)
유기용제 분산형 발수제1~5 중량부1 ~ 5 parts by weight of organic solvent dispersion type water repellent
(유기용제에 플루오로 카본 고형분(Fluorocarbon solids in organic solvents
20~40 중량% 분산)20-40 wt% dispersion)
물/메틸에틸케톤 혼합용액31~70 중량부(30~60 중량부 / 1~10 중량부)Water / methyl ethyl ketone solution 31 ~ 70 parts by weight (30 ~ 60 parts by weight / 1 ~ 10 parts by weight)
상기 조성 Ⅱ 에 있어서 유기용제 분산형 발수제로서는 톨루엔, 메틸에틸케톤 또는 디메틸 포름 아마이드(DMF) 등의 유기용제에 플루오로카본(FC) 30~40 중량%가 분산되어 있는 발수제를 사용한다. 상기 유기용제 분산형 발수제의 비중은 약 1 정도인 것이 바람직하며, 고형분인 플루오르 카본(FC)이 40 중량%를 초과하는 경우 w/o형 에멀젼 형성이 어렵게 된다.In the composition II, as the organic solvent-dispersed water repellent agent, a water-repellent agent in which 30 to 40% by weight of fluorocarbon (FC) is dispersed in an organic solvent such as toluene, methyl ethyl ketone or dimethyl formamide (DMF) is used. It is preferable that the specific gravity of the organic solvent-dispersed water repellent is about 1, and when the solid content of fluorocarbon (FC) exceeds 40% by weight, it becomes difficult to form a w / o emulsion.
폴리우레탄 수지로서는 폴리에테르형 폴리우레탄 수지를 사용하는 것이 바람직하다.It is preferable to use a polyether type polyurethane resin as a polyurethane resin.
유기용제로는 폴리우레탄계 수지 100 중량부에 대하여 메틸에틸케톤 10~30 중량부와 톨루엔 10~20 중량부가 혼합된 용제를 사용하며, 경화제로는 헥사메틸렌 디이소시아네이트를 사용한다.As the organic solvent, a solvent in which 10-30 parts by weight of methyl ethyl ketone and 10-20 parts by weight of toluene are mixed with respect to 100 parts by weight of polyurethane resin is used, and hexamethylene diisocyanate is used as a curing agent.
섬유포지로서는 폴리에스테르, 폴리아미드 또는 이들의 혼섬포지를 사용할 수 있다. 상기 조성 Ⅱ 의 w/o형 에멀젼 폴리우레탄 코팅 조성물을 섬유포지상에 두께 20~40㎛ 정도로 나이프 오버롤 코팅한 후 다단 건조하면 본 발명의 건식다공형 투습 방수포가 제조된다.As the fiber wrapping, polyester, polyamide or mixed sump these can be used. The dry porous moisture-permeable tarpaulin of the present invention is prepared by coating the w / o emulsion polyurethane coating composition of composition II on a fiber cloth with a knife overall roll thickness of about 20 to 40 μm and then drying it in multiple stages.
다단 건조 조건은 일반적으로 80℃에서 30초~1분 정도 1단계 건조한 후 120℃에서 30초~1분 정도 2단계 건조하고 150℃에서 30초~1분 정도 3단계 건조하는 것이 바람직하다. 본 발명에서는 특별하게 다단 건조 조건을 한정하는 것은 아니다.In general, the multistage drying condition is one step of drying at 80 ° C. for 30 seconds to 1 minute, followed by two steps of drying at 120 ° C. for 30 seconds to 1 minute, and three steps of drying at 150 ° C. for 30 seconds to 1 minute. In the present invention, the multistage drying conditions are not particularly limited.
이와 같이 제조된 본 발명의 건식다공형 투습 방수포는 고내수압과 동시에 고투습도의 특성을 갖는다.The dry porous permeable tarp of the present invention prepared as described above has the characteristics of high moisture permeability and high moisture resistance.
그 이유는 조성 (Ⅱ) 의 w/o형 에멀젼 폴리우레탄 코팅 조성물 중 발수제는 제 2 도와 같이 폴리우레탄 수지, 유기용제 및 경화제 등과 함께 에멀젼의 연속상(Continuous Phase)을 형성하여 유기용제와 물이 기화된 후에도 폴리우레탄 필름막 전체에 골고루 분포하게 된다.The reason for this is that the water-repellent agent in the w / o emulsion polyurethane coating composition of composition (II) forms a continuous phase of the emulsion together with the polyurethane resin, the organic solvent, and the curing agent as shown in FIG. Even after vaporization, it is distributed evenly throughout the polyurethane film.
그 결과 종래 물에 용해되어 기공의 주위에만 존재하는 수분산형 발수제를 사용하여 제조된 건식다공형 투습 방수포보다 내수압이 현저하게 향상된다. 또한 투습도 측면을 살펴보면 투습 메카니즘은 코팅층에 형성된 미세기공들에 의해 결정되므로 폴리우레탄 필름층을 소수화하였다고 해도 투습도 저하 현상은 일어나지 않는다.As a result, the water pressure is remarkably improved compared to the dry porous moisture permeable tarp prepared by using a water-dispersible water repellent that is dissolved in water and exists only around the pores. In addition, looking at the moisture permeability side, the moisture permeation mechanism is determined by the micropores formed in the coating layer, so even if the polyurethane film layer is hydrophobized, the moisture permeability decrease does not occur.
본 발명의 방법으로 제조된 건식다공형 투습 방수포의 투습도는 5,000g/㎡·24시간 이상이고, 내수압은 3,000 ㎜ H2O 이상이다.The moisture permeability of the dry porous permeable waterproof fabric prepared by the method of the present invention is 5,000 g / m 2 · 24 hours or more, and the water pressure is 3,000 mm H 2 O or more.
투습도 및 내수압의 측정 방법은 다음과 같다.The measurement method of moisture permeability and water pressure is as follows.
