Description
본 발명은 투습방수 섬유구조체 및 그의 제조방법에 관한 것으로 섬유구조체 표면에 다공성의 나노섬유 코팅층이 형성되어 투습성 및 방수성이 우수한 나노 섬유가 코팅된 투습방수 섬유구조체 및 그의 제조 방법에 관한 것이다. The present invention relates to a water-permeable waterproof fiber structure and a method of manufacturing the same, and a nanofiber-coated layer having a porous nanofiber coating layer formed on the surface of the fiber structure, and having a good moisture-permeable and waterproof property.
일반적으로 투습방수 섬유구조체는 100㎛의 빗방울이 섬유 밖에서 섬유 안으로 통과 못하게 하고 몸의 체내에서 방출되는 0.004㎛의 수분을 섬유 안에서 섬유 밖으로 나갈 수 있도록 피막층을 섬유구조체 위에 형성시켜 투습성과 방수성 등이 우수한 스포츠웨어, 군복, 텐트 등에 사용되는 섬유구조체를 의미한다.In general, the moisture-permeable waterproof fiber structure has excellent moisture permeability and waterproofness by forming a coating layer on the fiber structure so that raindrops of 100 μm do not pass into the fiber from the outside of the fiber and 0.004 μm of moisture released from the body can flow out of the fiber in the fiber. It refers to a fiber structure used for sportswear, military uniforms, tents and the like.
종래까지 섬유구조체에 투습방수 기능을 갖도록 하는 방법은 라미네이팅(Laminating) 방식에 의한 미세다공 성막법과 다이렉트 코팅방식에 의한 폴리우레탄 미다공 성막법, 그리고 초고밀도 직물에 의한 방법 등으로 폴리우레탄 고분자 수지를 섬유구조체 표면에 코팅하는 방법이다.Conventionally, a method of providing a moisture-permeable waterproof function to a fiber structure is a polyurethane porous resin by a microporous film forming method using a laminating method, a polyurethane microporous film forming method using a direct coating method, and an ultra high density fabric method. It is a method of coating on the surface of a fibrous structure.
상기 폴리우레탄을 이용한 다이렉트 코팅방식에 의한 종래의 투습방수직물은 DMF(디메칠포름아미드) 및 MEK(메틸에틸케톤) 등과 같이 환경에 유해한 솔벤트를 사용함으로써 환경오염을 초래하는 원인이 되어 최근에는 수분산형 폴리우레탄 코팅액을 이용하고 다단 건조하여 건식다공형 투습방수포를 제작법과 친수무공형의 폴리우레탄을 이용한 건식코팅법 등이 개발되고 있으나, 상기와 같이 폴리우레탄 고분자 수지에 의한 투습성 및 방수성의 특성의 섬유구조체는 폴리우레탄이 가지는 친수성으로 인해 수분이 원활하게 통과하지 못하는 단점이 있으며 제조과정에서 유기용매를 사용하여 섬유구조체의 염료가 유기용매에 의해 변색되는 문제가 발생할 수 있다.The conventional moisture-permeable waterproof fabric by the direct coating method using the polyurethane is the cause of environmental pollution by using solvents harmful to the environment, such as DMF (dimethylformamide) and MEK (methyl ethyl ketone), recently The method of manufacturing dry porous permeable waterproof fabric by using acid-type polyurethane coating solution and drying in multiple stages and dry coating method using hydrophilic non-porous polyurethane have been developed, but as described above, the moisture permeability and waterproof properties of polyurethane polymer resin The fiber structure has a disadvantage in that water does not pass smoothly due to the hydrophilic property of the polyurethane, and may cause a problem that the dye of the fiber structure is discolored by the organic solvent using an organic solvent in the manufacturing process.
따라서, 상기의 문제점이 없는 나노섬유를 이용하여 섬유구조체 표면에 미세다공이 형성된 나노섬유 코팅층을 형성한 투습방수 섬유구조체가 개발되고 있다. 대한민국 공개특허 제2007-0109001호에 기재되어 있는 "폴리우레탄 수지 박막층의 형성 방법"에서는 기저 섬유 위에 10 내지 30㎛의 두께로 폴리우레탄 나노부직포에 비하여 더 낮은 융점 또는 연화점을 가진 폴리에틸렌계 나노 부직포를 적층한 후 그 위에 10 내지 30㎛의 폴리우레탄 나노 부직포를 적층하여 라미네이팅 공정을 거쳐 투습방수포를 제조하는 방법으로서, 종래의 접착제를 사용하여 투습방수포를 제조하는 방법에 비하여 박막의 층을 형성할 수 있는 장점이 있으나 폴리에스테르계 섬유에 적용시, 폴리올레핀계와 폴리에스테르계가 상용성이 없어 계면분리가 되어 접착력이 저하되는 단점이 있으며, 이종의 고분자를 전기방사해야하는 공정을 거쳐 야 하기 때문에 공정이 복잡한 한계가 있다.Therefore, a moisture-permeable waterproof fiber structure in which a nanofiber coating layer in which micropores are formed on a surface of a fiber structure using nanofibers without the above problems has been developed. In the method for forming a polyurethane resin thin film layer described in Korean Patent Publication No. 2007-0109001, a polyethylene-based nano nonwoven fabric having a lower melting point or softening point than a polyurethane nanononwoven fabric with a thickness of 10 to 30 µm on a base fiber is used. After lamination, a method of manufacturing a moisture-permeable waterproof fabric by laminating a polyurethane nano nonwoven fabric having a thickness of 10 to 30 μm thereon, and forming a layer of a thin film as compared to a method of manufacturing a moisture-repellent waterproof fabric using a conventional adhesive. However, when applied to polyester-based fibers, there is a disadvantage that the adhesion between the polyolefin-based and polyester-based is incompatible with the interfacial separation, and the adhesive force is reduced, and the process is complicated because it has to go through the process of electrospinning heterogeneous polymers There is a limit.
또한, 종래의 투습방수 나노섬유 부직포는 기저 섬유와의 접착을 위해 별도의 접착제를 사용하거나 폴리우레탄 나노섬유에 비하여 더 낮은 융점 또는 연화점을 가진 폴리올레핀계 나노섬유 부직포를 형성시키는 단계를 포함한다. 별도의 접착제를 사용하여 기저 섬유에 적층시키는 방법은 투습성이 저하되고 전체적으로 섬유층이 두꺼워 진다는 단점이 있으며, 폴리올레핀계 나노 부직포를 형성시키는 방법은 투습방수 성능이 우수하나 두 번의 전기방사 공정을 거쳐야 되고 폴리올레핀계와 폴리에스테르계 직물과의 상용성이 낮아 계면분리현상에 의해 접착력이 약한 단점이 있다.In addition, conventional moisture-permeable nanofiber nonwoven fabrics include using a separate adhesive for bonding with the underlying fibers or forming a polyolefin-based nanofiber nonwoven fabric having a lower melting point or softening point than polyurethane nanofibers. The method of laminating to the base fiber by using a separate adhesive has a disadvantage in that the moisture permeability decreases and the overall fiber layer becomes thick.However, the method of forming the polyolefin-based nano nonwoven fabric has excellent moisture permeability, but it has to undergo two electrospinning processes. Due to the low compatibility between the polyolefin-based and polyester-based fabrics, there is a disadvantage in that the adhesive strength is weak due to the interface separation phenomenon.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 본 발명은 나노섬유층과 섬유구조체 사이에 별도의 접착제나 이종의 고분자를 사용하지 않고 섬유구조체 표면에 직접 나노섬유를 적층하여 나노섬유 코팅층을 형성하여 접착하는 성능이 우수한 나노섬유가 코팅된 투습방수 섬유구조체 및 그 제조방법을 제공하는 것을 목적으로 한다.

There are various types such as a single cleavage free radical photoinitiator and a hydrogen suction type free radical photoinitiator, and one of them can be selectively used, but the characteristics of each photoinitiator It would be desirable to mix and use according to
본 발명에서는 1-하이드록시사이클로헥실페닐케톤(시바 사, Igacure 184)과 디페닐 2,4,6-트리메틸벤조일 포스핀옥사이드(Darocur TPO)가 9:1 내지 1:9로 혼합되어 제조되는 것이 바람직할 것이다.In the present invention, 1-hydroxycyclohexylphenyl ketone (Igacure 184, Ciba) and diphenyl 2,4,6-trimethylbenzoyl phosphine oxide (Darocur TPO) is prepared by mixing 9: 1 to 1: 9 Would be desirable.
상기 1-하이드록시사이클로헥실페닐케톤과 디페닐 2,4,6-트리메틸벤조일 포스핀옥사이드가 혼합된 광개시제는 표면에서의 충분한 경화를 이룰 수 있게 해 줄 뿐만 아니라 디페닐 2,4,6-트리메틸벤조일 포스핀옥사이드를 사용함으로 인하여 내부까지 깊숙이 경화가 가능함으로써 두꺼운 코팅층까지도 충분히 경화가 가능한 장점이 있다.The photoinitiator mixed with the 1-hydroxycyclohexylphenyl ketone and diphenyl 2,4,6-trimethylbenzoyl phosphine oxide not only allows sufficient curing at the surface but also diphenyl 2,4,6-trimethyl By using benzoyl phosphine oxide it is possible to cure deep to the inside there is an advantage that can be sufficiently cured even a thick coating layer.
또한, 상기 광개시제는 고분자 방사액과 대비하여 1~10중량% 첨가되는 것이 바람직하며, 보다 바람직하게는 1~6중량% 첨가되는 것이다.In addition, the photoinitiator is preferably added 1 to 10% by weight, more preferably 1 to 6% by weight compared to the polymer spinning solution.
상기 광개시제의 함량이 10중량%를 초과하는 경우에는 전기방사시 나노섬유의 방사성이 현저하게 나빠져 전기방사 자체가 어렵게 될 뿐만아니라 나노섬유를 방사하여 나노섬유 코팅층을 형성시켜도 자외선 조사시 표면 경화가 빨리 되어 코팅층의 내부까지 경화가 되지않아 섬유구조체와의 접착력이 저하되고 광개시제의 함량이 0.1중량% 미만인 경우에는 자외선 조사에 의한 경화효과가 미미하여 섬유구조체와의 접착력이 저하된다.When the content of the photoinitiator exceeds 10% by weight, the radioactivity of the nanofibers is significantly worsened during electrospinning, which makes the electrospinning itself difficult, as well as the surface hardening during ultraviolet irradiation even when the nanofibers are radiated to form a nanofiber coating layer. Since the adhesive force to the fiber structure is not cured until the inside of the coating layer is lowered and the content of the photoinitiator is less than 0.1% by weight, the curing effect due to ultraviolet irradiation is insignificant and the adhesive force to the fiber structure is reduced.
상기 나노섬유 코팅층은 10 내지 30㎛의 두께로 섬유구조체 표면에 코팅되는 것이 바람직하다. 나노섬유 코팅층이 10㎛미만인 경우 투습성은 좋으나 방수성이 떨어질 수 있으며, 나노섬유 코팅층이 30㎛를 초과할 경우에는 방수성은 좋아지나 투습성이 떨어질 수 있다.The nanofiber coating layer is preferably coated on the surface of the fiber structure to a thickness of 10 to 30㎛. If the nanofiber coating layer is less than 10㎛ moisture permeability is good but the waterproofness may fall, if the nanofiber coating layer exceeds 30㎛ water resistance is good but the moisture permeability may be inferior.

상기 혼합단계는 고분자 방사액에 광개시제를 첨가하는 단계로 상기 광개시제를 고분자 방사액과 대비하여 0.1~10중량%를 고분자 방사액에 첨가하여 광개시제 가 첨가된 고분자 방사액을 제조한다.In the mixing step, a photoinitiator is added to the polymer spinning solution, and 0.1 to 10% by weight of the photoinitiator is added to the polymer spinning solution to prepare the polymer spinning solution to which the photoinitiator is added.
상기 광개시제는 1-하이드록시사이클로헥실페닐케톤(시바 사, Igacure 184)과 디페닐 2,4,6-트리메틸벤조일 포스핀옥사이드(Darocur TPO)를 9:1 내지 1:9로 혼합되어 제조하는 것이 바람직할 것이다.The photoinitiator is prepared by mixing 1-hydroxycyclohexylphenyl ketone (Igacure 184, Ciba) and diphenyl 2,4,6-trimethylbenzoyl phosphine oxide (Darocur TPO) in 9: 1 to 1: 9.

The nanofiber coating layer is preferably coated with a thickness of 10 to 30㎛.

Coating with an air chamber electrospinning method to produce a nonwoven fabric may produce a moisture-permeable waterproof fiber structure coated with a uniform nanofiber of the nanofiber coating layer.
