Description

투습방수 기능이 우수한 투습방수원단{Water-repellent fabric with excellent breathable waterproof function}{Water-repellent fabric with excellent breathable waterproof function,

본 발명은 원단기재층의 투습성을 그대로 유지할 수 있도록 하면서 투습방수 필름을 복층구조로 형성하여 투습도 및 방수 성능을 향상시키도록 한 투습도 투습방수 기능이 우수한 투습방수원단에 관한 것이다.The present invention relates to a moisture-permeable and waterproof fabric having a moisture-permeable and moisture-proofing and waterproofing function, which is capable of maintaining the moisture permeability of a fabric substrate layer while maintaining the moisture permeable and waterproof film in a multi-layer structure to improve the moisture permeability and waterproof performance.

투습방수 원단은 땀을 배출해주고, 비를 막아주는 투습방수성이 우수한 기능성 원단으로, 등산복, 야외 외출복, 침낭 등의 등산 및 일상생활의 아웃도어용으로 적용되고, 그 활용 범위가 넓어지고 있다.Breathable waterproof fabric is a functional fabric with excellent moisture permeability and water repellency that emits sweat and prevents rain. It is applied for climbing and outdoor activities such as climbing clothes, outdoor clothes and sleeping bags, and its application range is widening.

투습방수 원단은 물은 침투하지 못하게 하면서 몸에서 나는 땀은 수증기로 되어 바깥으로 배출시킴으로서 쾌적성을 부여하게 되어, 투습방수 원단으로 만들어진 의류는 착용감이 우수하다.The breathable waterproof fabric is designed to provide comfort by allowing the water to penetrate, while the sweat coming from the body is vaporized and discharged to the outside, and the breathable waterproof fabric is excellent in wearing comfort.

이러한 투습방수원단을 구성하는 방수소재는 PTFE 필름, 폴리에스터 필름, PU 라미네이션 등 3가지 소재로 분류되고, 고어텍스는 PTFE 필름으로 현재 전세계 투습방수 시장을 리드하고 있으나, 현존 투습방수 소재를 대체할 수 있는 새로운 소재 개발이 지속적으로 시도되고 있는 실정이다.These breathable and waterproof fabrics are classified into three materials such as PTFE film, polyester film, and PU lamination. Gore-Tex is currently leading the world's breathing and waterproof market with PTFE film, but it can replace existing breathable waterproof materials. The development of new materials that can be used in the future is being continuously tried.

종래에 투습방수원단의 제조는 이형지 위에 수지를 코팅하여 친수무공형 또는 다공성 필름(또는 PTFE 필름)을 제조한 후 이것을 접착제로 원단과 접합시켜 투습방수포를 제조하는 라미네이팅 방법이다. 이 경우 접합은 다공성 필름 위에 핫멜트 등의 접착제를 점자 형태로 간헐적이게 도포한 후, 원단기재와 본딩하는 도트 본딩방법 다공성 필름 전면에 접착제를 도포하여 원단기재와 본딩하는 전면본딩방법의 두가지 방법이 있으나 고기능성(고투습, 부드러운 촉감)이 요구되는 제품은 도트본딩방법이 주로 사용되고 있는 실정이다.Conventionally, in the production of the moisture-permeable and waterproof fabric, a resin is coated on a release paper to prepare a hydrophilic nonporous or porous film (or PTFE film), and then this is laminated with a fabric with an adhesive to produce a moisture-permeable tarpaulin. In this case, there are two methods of bonding: a dot bonding method in which an adhesive such as hot melt is applied on the porous film intermittently in a braille form on a porous film, and a front bonding method in which an adhesive is applied to the entire surface of the porous film Dot bonding methods are mainly used for products requiring high functionality (high moisture permeability, soft touch).

그러나 종래에는 도트본딩방법에 의한 다공성 필름과 원단기재를 본딩시 다공성 필름에 접착제를 도트 형태로 도포하여 원단기재와 본딩하는 것이 통상적이었며 그에 따라 다공성 필름이 갖는 투습성을 접착제가 저하시킴과 동시에 다공성 필름에 접착제가 도트 형태로 도포된 채로 원단기재로 접합하게 되면, 접착제가 원단기재의 조직 사이 기공을 막는 결과를 초래하여 투습방수원단으로 제품완료시 투습도가 더 저하되는 문제가 발생되었다.However, conventionally, when bonding the porous film and the base substrate by the dot bonding method, the adhesive is applied to the porous film in the form of dots and bonded to the base substrate. Thus, the moisture permeability of the porous film is lowered, When the adhesive is adhered to the substrate with the adhesive applied in the form of dots on the film, the adhesive causes the pores between the textures of the base material to be blocked, so that the moisture permeability of the product with moisture permeable waterproof material further lowers the moisture permeability.

즉, 다공성 필름과 원단기재 자체의 투습도가 우수하다할 지라도 두 소재를 본딩하는 과정에서 오히려 투습도가 저하시키게 되었으며, 이에 투습도가 저하된 그 상태로 제품을 완성할 수 밖에없는 문제점이 있었던 것이다.That is, although the moisture permeability of the porous film and the fabric substrate itself is excellent, the moisture permeability is lowered in the process of bonding the two materials, and the product has to be completed in such a state that the moisture permeability is lowered.

또한, 도트본딩방법에서는 접착제가 도트 형태로 간헐적으로 도포됨에 따라 원단기재와 접착제와의 접점이 매우 적어 충분한 상태(常態) 접착 강도를 유지할 수 없는 단점으로 인해 기재간의 박리를 일으키는 경우가 있었다.Further, in the dot bonding method, since the adhesive is intermittently applied in the form of dots, there are cases where the contact between the base material and the adhesive is so small that the adhesive strength can not be maintained in a sufficient state (normal state).

특히, 상기 방법으로 제조한 의복 등을 물세탁하면, 물이나 세제 등의 영향에 의해 접착제의 접착 강도가 현저하게 저하하고, 그 결과, 기재층에서 다공성필름이 박리를 일으켜 분리되는 문제가 있었다.Particularly, when the clothes or the like prepared by the above method are washed with water, the adhesive strength of the adhesive significantly decreases due to the influence of water or a detergent, and as a result, there is a problem that the porous film is separated from the base layer by separation.

본 발명에 따른 투습방수 기능이 우수한 투습방수원단은 원단 기재층(10)과, 상기 원단 기재층(10)의 기공이 막히는 것을 최소화하도록 전사되는 핫멜트접착층(20)과, 상기 원단 기재층(10)으로 핫멜트접착층(20)에 의해 투습방습을 위한 라미네이트 되는 투습방수필름층(30)으로 구성되며,The moisture permeable and waterproof fabric excellent in moisture permeability and waterproof function according to the present invention comprises a base material layer 10, a hot melt adhesive layer 20 transferred to minimize clogging of the pores of the base material layer 10, ), And a moisture permeable and waterproof film layer (30) laminated for moisture and moisture proofing with the hot melt adhesive layer (20)

상기 투습방수필름층(30)은 연신 다공질 폴리테트라플루오로에틸렌(ePTFE)필름(31)과, 상기 ePTFE 필름(31) 위에 투명한 폴리에스테르로 이루어진 투습보강필름(32)이 이중 적층 본딩된 복합구조로 구성되는 것을 특징으로 한다.The moisture permeable and waterproof film layer 30 is composed of a stretched porous polytetrafluoroethylene (ePTFE) film 31 and a moisture permeable reinforcing film 32 made of transparent polyester on the ePTFE film 31 . ≪ / RTI >

원단 기재층(10)은 폴리에스테르, 나일론, 재생섬유, 천연섬유 등의 소재를 사용한 직물 또는 편물인 것으로 높은 밀도와 직조로 짜여진 직물, 편물, 부직포중 어느 것도 가능하다.The fabric substrate layer 10 is fabric or knitted fabric using materials such as polyester, nylon, regenerated fiber, natural fiber, etc., and any of woven fabric, knitted fabric and nonwoven fabric woven with high density and woven fabric is possible.

상기 핫멜트접착층(20)은 원단 기재층(10)을 형성하는 원단조직의 위사와 경사가 교차하는 교차지점마다 도트 인쇄하게 된다. 이에 따라 원단 기재층(10)의 조직 사이로 형성된 기공이 핫멜트접착층(20)에 의해 막히는 것이 획기적으로 방지됨에 따른 원단 기재층(10)이 갖는 고유의 투습성이 저해됨을 방지하여 투습효과를 높히게 된다.The hot-melt adhesive layer 20 is dot-printed at each intersection where the weft yarns and the warp yarns of the fabric texture forming the far-end base layer 10 cross each other. Accordingly, the pores formed between the textures of the far-end base layer 10 are prevented from being clogged with the hot-melt adhesive layer 20, thereby preventing the inherent moisture permeability of the far-end base layer 10 from being hindered, .

이와 같은 원단 기재층(10)의 조직 교차지점마다 핫멜트접착층(20)을 도트방식으로 형성하기 위해서는 조직의 교차지점을 분석하기 위한 원단조직을 정밀분석하는 선공정이 요구되고, 그에 따른 이형지 필름의 전사지로 핫멜트접착제를 원단 조직의 교차지점에 부합한 직경과 간격으로 도트형상으로 프린트하여 원단 기재층(10)으로 전사시킴으로써, 원단 기재층(10)으로 핫멜트접착층(20)을 형성하게 된다.In order to form the hot-melt adhesive layer 20 in a dot-like manner at each tissue crossing point of the far-end substrate layer 10, a line process for precisely analyzing a fabric texture for analyzing a crossing point of the tissue is required, The hot melt adhesive layer 20 is formed of the far ultimate base layer 10 by printing the hot melt adhesive in a dot shape at a diameter and an interval corresponding to the crossing points of the fabric texture and transferring the hot melt adhesive layer to the far ultimate base layer 10 as a transfer paper.

It has a high porosity to obtain a moisture permeability and is excellent in durability without surface delamination, is flexible, is very hydrophobic, and is excellent in chemical resistance and heat resistance.

상기 투습보강필름(32)은 투습성을 갖는 무색 투명한 무공질 폴리에스테르 필름으로 구비되어, ePTFE 필름의 상부에 핫멜트접착제에 의해 도트방식으로 라미네이트하여 복층구조로 구성하여 ePTFE 필름(31)의 표면을 보강함에 따른 원단 기재층(10)으로 ePTFE 필름(31)의 접착내구성을 높히고, 투습도 및 방수성을 보다 향상시키게 된다.The moisture permeable reinforcing film 32 is a colorless transparent non-porous polyester film having moisture permeability. The moisture permeable reinforcing film 32 is laminated on the upper side of the ePTFE film by a hot-melt adhesive in a dot manner to form a multi-layer structure to reinforce the surface of the ePTFE film 31 The durability of adhesion of the ePTFE film 31 can be enhanced by the far-end base layer 10 according to the present invention, and the moisture permeability and water resistance can be further improved.
