종래의 공지된 카펫 재로는 일본특허(특개 소 52-53980호, 특개 소 61-132667호)가 있는데 전술한 공지의 특허는 부직포 기포의 표면에 의장을 목적으로 코드조나 벨로어(velour)조 등의 파일을 형성한 파일층을 가지고 그 하층에 파일층을 고정시켜 내마모성 향상 및 강성을 부여하기 위하여 라텍스가 함침된 함침층을 갖는 타입의 카펫에 관한 것이다.Conventionally known carpet materials include Japanese Patents (Japanese Patent Application Laid-Open No. 52-53980, Japanese Patent Application Laid-Open No. 61-132667), and the above-mentioned known patents are used for the purpose of designing a surface of a nonwoven fabric bubble or a bellow. The present invention relates to a carpet of a type having an impregnated layer impregnated with a latex-impregnated layer in order to improve abrasion resistance and give rigidity by fixing a pile layer having a pile formed of a pile.

또한, 일본특허(특개 소 59-140175호, 특개 소 57-205251호, 특개 소 59-204982호)는 자동차용 카펫 재로 라텍스 코팅층의 하층에 폴리에틸렌, 폴리프로필렌, 폴리아미드 필름 시트 또는 탄산칼슘(calcium carbonate)의 무기질을 함침한 에틸렌비닐아세테이트(EVA, Ethylene vinyl acetate) 공중합체 등의 열가소성(Thermoplasticity) 시트로 이루어지는 백킹(backing)층을 라미네이트한 적층제 타입의 것을 제시하고 있다.In addition, Japanese Patents (Japanese Patent Laid-Open No. 59-140175, Japanese Patent Laid-Open No. 57-205251, Japanese Patent Laid-Open No. 59-204982) are polyethylene, polypropylene, polyamide film sheets or calcium carbonate underneath the latex coating layer as a carpet material for automobiles. The laminate type which laminated | stacked the backing layer which consists of thermoplastic sheets, such as an ethylene vinyl acetate (EVA) copolymer impregnated with the mineral of carbonate), is proposed.

더욱이, 라텍스를 이용하지 않는 것으로써 파일층, 기포층에 같은 양의 심초구조를 가지는 열융착 섬유를 배합한 타입은 일본특허(특개 평7-9925호)에 기재되어 있다.Moreover, the type which mix | blended the heat-sealing fiber which has the same amount of the poncho structure to the pile layer and the bubble layer without using latex is described in Japanese Patent Laid-Open No. 7-9925.

The surface layer of the floor carpet is coated with these backing layers, so that the floor carpet must be subjected to a process that requires a large amount of heat such as drying or melting in order to become a floor carpet. There was a problem that the generation of volatile organic compounds and recycling powder in the vehicle interior due to use.

또한, 전술한 종래의 기술들로 제조된 플로어 카펫은 중량이 무겁기 때문에 차량의 연비를 저하시키는 문제점이 있었다.In addition, the floor carpet manufactured by the above-described conventional techniques has a problem of lowering the fuel efficiency of the vehicle because the weight is heavy.

또한, 전술한 종래에 기술은 라텍스나 폴리에틸렌이 코팅된 부직포 카펫을 성형하는 공정에서 트리밍 스크랩을 대량 발생시키기 때문에 재활용이 어려워 폐기처분 되고 있으며, 폐기처분 시에 다량의 이산화탄소 및 유해가스를 발생시켜 환경을 오염시키는 문제점이 있었다.
In addition, the conventional technique described above is difficult to recycle because it generates a large amount of trimming scrap in the process of forming a latex or polyethylene-coated nonwoven carpet, and is disposed of, and a large amount of carbon dioxide and harmful gases are generated during disposal. There was a problem polluting.
