본 발명은 내스크렛치성(Amti-scratch property)이 우수한 기능성 다층필름에 관한것으로서, 보다 구체적으로는 기능성 필름을 슬릿팅(sliting)하여 제조한 원사를 경사 및/또는 위사로 사용하여 제조한 기능성 원단 양면에 보호용 필름이 열접착되어 긁힘에 대한 저항성(이하"내스크렛치성"이라고 한다)이 우수하여 재귀 반사 기능 또는 홀로그램 기능등을 장기간 그대로 유지할수 있으며 환경오염문제도 예방할수 있는 기능상 다층필름에 관한것이다.The present invention relates to a functional multilayer film having excellent scratch-resistance property, and more specifically, to a functional film manufactured by using a yarn prepared by slitting the functional film as a warp yarn and / or weft yarn. The protective film is heat-sealed on both sides of the fabric, so it is excellent in scratch resistance (hereinafter referred to as "scratch resistance"), so it can maintain recursive reflection function or hologram function for a long time and also prevent environmental pollution problems. It's about.

재귀반사 기능, 홀로그램 기능등을 갖는 필름(이하"기능성필름"이라고 한다)을 그대로 사용할 경우에는 내스크렛치성이 약하여 표면에 긁힘자국이 많이 발생되게 되고, 그로인해 재귀반사 또는 홀로그램등의 특수기능성이 빨리 상실되는 문제가 발생하게 된다.When using a film having a retroreflective function or a hologram function (hereinafter referred to as a "functional film") as it is, scratch resistance is weak and a lot of scratches are generated on the surface, which causes special functionalities such as retroreflective or hologram. This problem is quickly lost.

이와 같은 문제를 해결하기 위한 종래기술로는 기능성 필름 양면에 폴리비닐클로라이드(PVC)필름(보호용 필름)을 열접착시켜 내스크렛치성을 개선하는 방법이 제안, 실시되고 있으나, 상기 방법은 내스크렛치성을 개선할수 있지만 소각시 환경오염물질인 다이옥신이 다량 발생하는 폴리비닐클로라이드(PVC)필름을 사용하기 때문에 환경오염의 문제점이 있었다.As a conventional technique for solving such a problem, a method of improving the scratch resistance by heat-bonding a polyvinyl chloride (PVC) film (protective film) on both surfaces of a functional film has been proposed and implemented, but the method is Nask Although it can improve the latching property, there is a problem of environmental pollution because it uses polyvinyl chloride (PVC) film which generates a large amount of dioxin, which is an environmental pollutant when incinerated.

최근에는 기능성 필름 양면에 소각시 환경오염물질인 다이옥신이 발생되지 않는 폴리우레탄수지, 공중합 폴리올레핀계 수지 또는 스티렌-부타디엔 스티렌(SBS) 수지로 이루어진 필름(보호용 필름)을 열접착시켜 내스크렛치성을 개선함과 동시에 환경오염 문제도 해결하고자 하였으나, 상기의 보호용필름들은 이들의 물성특성상 기능성 필름과 거의 열접착되지 않아 아직 상용화 되지 못하는 실정이다.Recently, a film (protective film) made of a polyurethane resin, a copolyolefin resin, or a styrene-butadiene styrene (SBS) resin, which does not generate dioxin, which is an environmental pollutant when incinerated on both functional films, is heat-bonded. While attempting to solve the environmental pollution problem at the same time, the protective films are not yet commercialized because they are hardly heat-bonded with functional films due to their physical properties.

본 발명의 목적은 이와 같은 종래기술의 문제점들을 해소함으로서 내스크렛치성이 우수함과 동시에 환경오염 문제도 해결할수 있는 기능성 다층 필름을 제공 하기 위한 것이다.An object of the present invention is to provide a functional multilayer film that can solve the problems of environmental pollution as well as excellent scratch resistance by solving the problems of the prior art.

본 발명은 기능성필름의 고유한 기능성을 그대로 유지 하면서도 폴리우레탄 수지등의 보호용 필름과 열접착성이 향상된 기능성원단을 제조하고, 그 양면에 상기의 보호용 필름을 열접착시켜 내스크렛치성이 우수함과 동시에 환경오염 문제가 없는 기능성 다층 필름을 제공하고자 한다.The present invention manufactures a functional fabric with improved thermal adhesiveness and a protective film such as a polyurethane resin while maintaining the inherent functionality of the functional film, and excellent heat resistance by heat-bonding the protective film on both sides thereof. At the same time, to provide a functional multilayer film without the problem of environmental pollution.

이를 위해 본 발명에서는 기능성 필름을 슬릿팅(stiting)하여 제조한 원사를 경사 및/또는 위사로 사용하여 기능성 원단을 제조하는 방법도 제공하고자 한다.
To this end, the present invention also provides a method for producing a functional fabric using a yarn prepared by slitting a functional film as a warp and / or weft yarn.
