본 발명은 헬스복이나 윈드 스토퍼 및 싸이클복이나 등산복, 스키복 및 장갑이나 점퍼와 같은 다양한 스포츠 및 아웃도어 의류를 만들기 위한 기능성 원단에 관한 것으로, 더욱 상세하게는 고탄력의 신축지 표면에 투습성 폴리우레탄 필름을 엠보싱 형태로 도트 융착 형성한 후, 상기 투습성 폴리우레탄 필름의 표면에 또 다른 고탄력의 신축지를 접착 하여 3중 원단이 형성되게 함으로써, 상기 이중의 신축지에 융착 및 접착된 투습성 폴리우레탄 필름에 의해 우수한 투습성과 방수성을 확보하면서도 신축지와의 사이에 생성된 공기층에 의해 보온성이 뛰어난 것이고, 내외면 모두 신축지로 이루어져 있으므로 부드러운 터치감은 물론 우수한 신축성을 갖게 한 보온성 방풍원단에 대한 것이다.The present invention relates to a functional fabric for making a variety of sports and outdoor clothing, such as fitness clothes, wind stoppers and cycle clothes, mountaineering clothes, ski clothes and gloves or jumpers, and more specifically a moisture-permeable polyurethane film on the surface of high-strength stretch paper After forming a dot fusion in the form of embossing, by bonding another high-strength stretch paper to the surface of the moisture-permeable polyurethane film to form a triple fabric, excellent by the moisture-permeable polyurethane film fused and bonded to the double stretch paper While maintaining moisture permeability and waterproofness, it is excellent in heat retention by the air layer generated between the stretch paper, and since it is made of stretch paper both inside and outside, it is about a heat-resistant windproof fabric having a soft touch feeling and excellent elasticity.

일반적으로 헬스복이나 윈드 스토퍼 및 싸이클복이나 등산복과 스키복 또는 스포츠용 장갑이나 점퍼와 같은 스포츠 및 아웃도어 의류나 피복은 사용 목적의 특성상 다양한 기능을 갖는 원단을 사용하여 제작하여야 하는 것인데, 통상적으로 상기 아웃도어용 의류에 사용되는 원단은 투습성이나 방수성 및 방풍성과 발수성 그리고 방오성과 보온성을 갖고 있어야 하는 것이다.In general, sports and outdoor clothing or clothing, such as fitness clothes, wind stoppers and cycle clothes, mountaineering clothes and ski clothes or sports gloves or jumpers, should be manufactured using fabrics having various functions due to the characteristics of the intended use. Fabrics used for outdoor clothing should be breathable, waterproof, windproof, water repellent, antifouling and warm.

상기와 같은 원단에 투습성 및 방수성을 갖게 하기 위해서는 고어텍스 원단과 같이 습기와 공기의 순환은 이루어지면서도 물은 통과하지 못할 정도의 밀도를 갖도록 직조한 원단을 사용하는 것이 보편적이다.In order to provide moisture permeability and waterproofness to the fabric as described above, it is common to use a woven fabric having a density such that Goretex fabric has moisture and air circulation but water cannot pass.

그러나, 상기와 같은 조밀구조의 직조물로 된 원단은 투습성 및 방수성은 탁원할 반면 신축성이 떨어지므로 운동량이나 활동량이 많은 아웃도어에는 적합하지 않을 수도 있을 것이다.However, the fabric of the woven fabric of the dense structure as described above may be unsuitable for outdoor having a high amount of exercise or activity because the elasticity is poor while the moisture permeability and waterproofness are turbid.

이에 따라, 근자에 들어서는 고탄성의 고무사가 원사와 함께 직조된 형태의 신축지를 이용하여 된 기능성 원단이 주로 사용되고 있는데, 상기와 같은 기능성 원단은 우수한 방수성 및 투습성을 확보하기 위해 원단의 내면에 별도의 폴리우레탄 필름을 부착하여 제작하게 된다.Accordingly, functional fabrics made of stretch paper woven together with high-elastic rubber yarn in the roots are mainly used. Such functional fabrics have a separate poly on the inner surface of the fabric to secure excellent waterproofness and moisture permeability. It is produced by attaching a urethane film.

상기의 투습성 폴리우레탄 필름은 매우 얇고 부드러운 질감을 갖고 있으면서도 신축성이 뛰어나 신축지의 일면에 부착하여 원단을 제작하게 되면 상기 신축지와 폴리우레탄 필름 자체의 특성으로 인해 우수한 신축성을 보이면서도, 상기 폴리우레탄 필름이 갖고 있는 고유의 투습성과 방수성 및 방풍성을 함께 얻을 수 있게 된다.The moisture-permeable polyurethane film has a very thin and soft texture, but also has excellent elasticity, and when the fabric is attached to one side of the stretch paper to produce a fabric, the polyurethane film shows excellent elasticity due to the characteristics of the stretch paper and the polyurethane film itself. The inherent moisture permeability, waterproofness, and windproofness can be obtained together.

따라서, 상기와 같은 투습성 폴리우레탄 필름을 사용한 신축지로 된 기능성 원단은 등산복이나 스키복과 같은 다양한 아웃도어 의류에 널리 사용되고 있는 추세이다.Therefore, the functional fabric made of stretch paper using the moisture-permeable polyurethane film as described above is a trend that is widely used in various outdoor clothing, such as mountaineering clothes and ski clothes.

그러나, 상기와 같은 신축성 원단은 내면에 폴리우레탄 필름이 부착되어 있는 상태이므로 상기의 원단 즉, 폴리우레탄 필름이 피부에 직접 닿을 경우에는 터치감이 크게 떨어질 뿐만 아니라 땀이나 습기를 효과적으로 배출하지 못하는 문제점을 갖고 있는 것이다.However, the above-described stretch fabric is a state in which the polyurethane film is attached to the inner surface, so when the fabric, that is, the polyurethane film is directly in contact with the skin, the touch is not greatly reduced and sweat or moisture is not effectively discharged. To have.

즉, 상기와 같은 폴리우레탄 필름은 폴리우레탄 수지용액을 경화시켜 만들어진 것으로 피부에 달라붙는 현상이 빈번하게 발생하므로 과도하거나 격렬한 운동이나 움직임을 통해 땀이 배출되면 상기의 땀이 오히려 폴리우레탄 필름의 미세기공층을 막아버리게 되는 현상이 발생하게 된다.That is, such a polyurethane film is made by curing the polyurethane resin solution, so that the phenomenon of sticking to the skin frequently occurs, if the sweat is discharged through excessive or intense movement or movement, the above sweat is rather fine in the polyurethane film. The phenomenon of blocking the pore layer occurs.

또한, 매끄러운 표면으로부터 미세기공층을 갖고 있는 폴리우레탄 필름은 피부와 직접 맞닿게 되면 피부가 미세기공층을 막아 공기의 소통을 방해하거나 폴리우레탄 필름이 부피에 달라붙어 이물감을 느끼게 되는 것이다. 따라서, 상기의 폴리우레탄 필름은 합성수지로 만들어짐에 따라 이와 같은 폴리우레탄 필름이 피부에 직접 닿을 경우 부드러운 터치감을 얻을 수 없어 피부에 직접 닿는 형태의 의류에 적용하는데에는 많은 어려움이 있는 것이다.In addition, when a polyurethane film having a microporous layer from a smooth surface is in direct contact with the skin, the skin blocks the microporous layer, preventing air from communicating, or the polyurethane film sticks to a volume to feel a foreign object. Therefore, as the polyurethane film is made of synthetic resin, it is difficult to apply it to a garment of direct contact with the skin because such a polyurethane film does not obtain a soft touch when directly touching the skin.

특히, 상기의 신축성 원단은 우수한 신축성을 갖고 있는 반면 보온성이 극히 떨어지므로 동절기에는 여러 겹의 의류를 겹쳐입거나 원단 자체를 두껍게 제작하여야 하므로 사용이 불편할 뿐더러 신축성이 저하되는 것이고, 제작 과정이 번거롭고 고비용의 생산비를 지출하여야 하는 폐단을 갖고 있는 것이다.In particular, the above-mentioned stretch fabric has excellent elasticity, but the thermal insulation is extremely inferior, so in winter, it is necessary to overlap several layers of clothing or to make the fabric itself thick, which is not only inconvenient to use, but also the elasticity is reduced, and the manufacturing process is cumbersome and high cost. We have a need to spend the cost of production.

본 발명은 전기한 바와 같은 문제점을 개선한 것으로서, 고탄력의 신축지의 표면에 투습성 폴리우레탄 필름을 부착하고, 상기 투습성 폴리우레탄 필름의 표면에 또 다른 신축지를 부착 형성하되, 상기 투습성 폴리우레탄 필름은 신축지의 표면에 대하여 벌집모양을 갖도록 엠보싱 롤러로 도트 용융형태로 압착하고, 상기 벌집모양의 투습성 폴리우레탄 필름의 표면에 접착제를 도포한 후 또 다른 신축지를 접착 형성하여 3중 원단을 형성함에 따라,The present invention is to solve the problems as described above, attaching a moisture-permeable polyurethane film on the surface of the high-strength stretch paper, and attaching another stretch paper on the surface of the moisture-permeable polyurethane film, the moisture-permeable polyurethane film is stretched By pressing in an embossed roller to have a honeycomb shape with respect to the surface of the paper in a dot-melt form, applying an adhesive to the surface of the honeycomb-permeable moisture-permeable polyurethane film, and then forming another stretch paper to form a triple fabric,

내외면의 신축지를 통해 우수한 터치감을 연출하면서도, 신축지와 신축지의 사이에서 벌집모양의 엠보싱 접착상태인 투습성 폴리우레탄 필름이 갖는 비접착의 공기층으로 인해 우수한 보온성을 제공하므로, 기존의 투습성과 방수성은 그대로 유지하면서도 뛰어난 보온성과 부드러운 터치감 및 우수한 신축성을 함께 연출하고자 한 보온성 방풍원단 및 그 제조방법을 제공함에 본 발명의 목적이 있는 것이다.While providing excellent touch feeling through the inner and outer sides of the stretch paper, it provides excellent heat retention due to the non-adhesive air layer of the moisture-permeable polyurethane film in the honeycomb embossed adhesive state between the stretch paper and the stretch paper. It is an object of the present invention to provide a thermal insulation windproof fabric and a method of manufacturing the same, while maintaining the same, and to produce excellent warmth and soft touch and excellent elasticity.

상기한 바와 같은 목적을 달성하기 위한 본 발명은, 제1신축지의 표면에 투습성 폴리우레탄 필름이 부착되고, 상기 투습성 폴리우레탄 필름의 표면에 제2신축지를 부착 형성하되,The present invention for achieving the above object, the moisture-permeable polyurethane film is attached to the surface of the first stretch paper, the second elastic paper is attached to the surface of the moisture-permeable polyurethane film is formed,

상기 투습성 폴리우레탄 필름과 제1신축지 및 제2신축지의 사이에는 엠보싱 형태로 접착된 투습성 폴리우레탄 필름에 의한 공극 내에 공기층이 형성되도록 구 성하여 되는 것이다.Between the moisture-permeable polyurethane film and the first stretch paper and the second stretch paper is to be configured to form an air layer in the voids by the moisture-permeable polyurethane film bonded in an embossed form.

본 발명은, 외부로부터의 바람이나 물은 차단시켜주면서도 땀은 효과적으로 배출시키는 투습성과 방수성이 뛰어나면서도, 이중의 신축지에 의해 내,외의 부드러운 터치감을 얻을 수 있어 더욱 다양한 형태의 의류를 만들 수 있는 것이며, 투습성 폴리우레탄 필름과 신축지의 사이에 생성되는 공기층은 의복이나 피복 등의 우수한 보온성을 제공하는 것이고, 고탄력의 신축지에 엠보싱 형태로 융착 및 접착되는 폴리우레탄 필름에 의해 뛰어난 신축성을 연출하는 것이다.The present invention is excellent in moisture permeability and waterproofness to block the wind and water from the outside while effectively discharging sweat, and the double stretch paper makes it possible to obtain a soft touch feeling inside and outside, thereby making it possible to make clothes of various types. The air layer produced between the moisture-permeable polyurethane film and the stretch paper provides excellent thermal insulation such as clothing and coating, and produces excellent elasticity by the polyurethane film fused and bonded to the high elastic stretch paper by embossing.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 보온성 방풍원단의 확대 절개 사시도이다.1 is an enlarged cutaway perspective view of an insulating windbreak fabric according to the present invention.

도시와 같이 본 발명에 따른 보온성 방풍원단은, 고탄력의 제1신축지(10)와 제2신축지(30)를 별도의 투습성 폴리우레탄 필름(20)에 의해 서로 융착 및 접착 형성한 것으로서, 상기의 투습성 폴리우레탄 필름(20)은 상기 제1신축지(10)와 제2신축지(30)에 대하여 도트 형태로 된 벌집 모양의 엠보싱 형상으로 융착 및 접착된 것이다.Thermal insulation windproof fabric according to the present invention, as shown in the first elastic paper 10 and the second elastic paper 30 is fused and bonded to each other by a separate moisture-permeable polyurethane film 20, The moisture-permeable polyurethane film 20 is fused and bonded to the first stretch paper 10 and the second stretch paper 30 in a honeycomb-like embossed shape in the form of dots.

이에 따라, 상기의 투습성 폴리우레탄 필름(20)의 상,하면에는 제1신축지(10)과 제2신축지(30)의 사이에서 도트 형태의 엠보싱 융착과 접착에 따라 비융착 및 부접착부인 공극으로 인한 다수의 공기층(1)(1')이 형성되는 것으로서, 상기의 공기층(1)(1')은 원단에 대하여 우수한 보온성과 뛰어난 신축성을 제공하게 된다.Accordingly, the upper and lower surfaces of the moisture-permeable polyurethane film 20 are non-welded and non-adhesive parts according to dot-embossed fusion and adhesion between the first stretch paper 10 and the second stretch paper 30. As a plurality of air layers (1) (1 ') due to the voids are formed, the air layer (1) (1') to provide excellent thermal insulation and excellent elasticity for the fabric.

여기서, 상기의 투습성 폴리우레탄 필름(20)은 특허등록 제045257호와 같이, 원단기재의 조직사이 공극에도 고분자 충전물을 1~10g/yd의 충전량으로 충전시키고 이를 발수처리시킨 다음 그 위에다 폴리우레탄 중합체의 고형분이 10~40중량부이고, 극성 유기용매가 50~100중량부, 음이온 계면활성제가 0.5~5중량부인 조성으로 이루어진 폴리우레탄 유기용제용액을 도포하고, 이를 1~20%의 DMF수용액중에서 습식 응고하여 미세공기층을 형성시킨 다음 이를 수세 건조하여 상기 원단기재로부터 폴리우레탄 필름을 연속적으로 박리시켜 이루어지는 것이다.Herein, the moisture-permeable polyurethane film 20 is filled with a polymer filler in a filling amount of 1 ~ 10g / yd to the pores between the tissue of the fabric base material, as described in Patent Registration No. 05257, water-repellent treatment and then on the polyurethane polymer thereon The solid content of 10 to 40 parts by weight, a polar organic solvent of 50 to 100 parts by weight, an anionic surfactant of 0.5 to 5 parts by weight of the composition of a polyurethane organic solvent solution was applied, and in 1 to 20% DMF aqueous solution Wet coagulation to form a micro-air layer and then washed with water to dry the polyurethane film from the fabric substrate continuously.

이와 같은 투습성 폴리우레탄 필름(20)은 우수한 방수성과 함께 투수성을 갖고 있는 것이고, 연신률이 뛰어나 신축성 원단 등에 널리 사용되고 있는 것이다.Such a moisture-permeable polyurethane film 20 has excellent water resistance and water permeability, and has excellent elongation and is widely used in stretch fabrics and the like.

이에 상기와 같은 투습성 폴리우레탄 필름(20)을 이용하여 본 발명의 보온성 방풍원단을 제조하는 과정을 첨부도면에 의해 설명한다.This will be described by the accompanying drawings a process for producing the insulating windproof fabric of the present invention using the moisture-permeable polyurethane film 20 as described above.

본 발명에서는 도 2a의 도시와 같이 투습성 폴리우레탄 필름(20)의 일면에 탈리지(21)가 부착된 상태의 필름지를 구비한 후, 상기의 투습성 폴리우레탄 필름(20)의 노출 표면에 대하여 별도의 제1신축지(10)를 합지시켜 이들을 엠보싱롤러(40)로 투입시킨다.According to the present invention, as shown in FIG. 2A, after the film paper having the tackage 21 is attached to one surface of the moisture-permeable polyurethane film 20, the film is separated from the exposed surface of the moisture-permeable polyurethane film 20. First stretch paper 10 is laminated, and these are put into the embossing roller 40.

이에 따라 도 2b의 도시와 같이 엠보싱롤러(40)를 통과하면서 상기의 투습성 폴리우레탄 필름(20)은 엠보싱롤러(40)의 돌출 무늬에 따라 부분적으로 가압되면서 상기 제1신축지(10)에 벌집 모양으로의 도트 융착이 이루어지는 것인데, 가열 상태인 상기의 엠보싱롤러(40)가 제1신축지(10)와 투습성 폴리우레탄 필름(20)을 도트형태로 부분 가압함에 따라 엠보싱롤러(40)의 돌출무늬는 투습성 폴리우레탄 필름(20)을 열변형시키면서 상기 제1신축지(10)와 융착되게 하는 것이다. 이때 상기의 투습성 폴리우레탄 필름(20)은 엠보싱롤러(40)의 돌기부분에 의해 가압 융착된 부분과 융착되지 않은 부분으로 나뉠 수 있는 것으로서 가압 융착된 부분의 사이에 위치하는 미융착부는 제1신축지(10)와 투습성 폴리우레탄 필름(20)과의 공극을 형성하게 되므로 결국 이들 공극이 공기층(1)의 역할을 수행하게 되는 것이다.Accordingly, while passing through the embossing roller 40 as shown in FIG. 2B, the moisture-permeable polyurethane film 20 is honeycombed to the first stretchable paper 10 while being partially pressed according to the protruding pattern of the embossing roller 40. The dot fusion is formed in a shape, but the embossing roller 40 in a heated state protrudes the embossing roller 40 by partially pressing the first stretchable paper 10 and the moisture-permeable polyurethane film 20 in the form of dots. The pattern is such that the moisture-permeable polyurethane film 20 is fused with the first stretchable paper 10 while being thermally deformed. In this case, the moisture-permeable polyurethane film 20 may be divided into a pressure-welded portion and a non-fusion portion by the protrusion portion of the embossing roller 40, and the non-fused portion located between the pressure-fused portions is first stretched. Since the pores 10 and the moisture-permeable polyurethane film 20 are formed, these pores will eventually serve as the air layer 1.

따라서, 상기와 같은 엠보싱롤러(40)를 통과한 제1신축지(10)와 투습성 폴리우레탄 필름(20)은 엠보싱 형태로 가압된 부분에서의 접합상태를 갖게 될 것이다.Therefore, the first stretchable paper 10 and the moisture-permeable polyurethane film 20 passing through the embossing roller 40 as described above will have a bonding state in the pressurized portion in the embossing form.
