It is easy to heat fusion with other building interior materials by forming non-woven fabric, and it has excellent hydrophilicity as the non-woven fabric is made of short fiber, and it is excellent in reaction with water-based paint and water-based adhesive, and it is processed by surface processing through calender roller. It is possible to prevent the standing up or agglomeration of cilia during paint work, and to a nonwoven fabric for building interior materials which is harmless to the human body by forming a nonwoven fabric with only polypropylene and polyethylene.

부직포(不織布, non-woven fabric)란 피복재료의 하나로, 섬유를 직포공정을 거치지 않고, 평행 또는 부정방향(不定方向)으로 배열하고 합성수지 접착제로 결합 하여 펠트 모양으로 만든 것으로 원료 섬유로는, 처음에는 솜 ·비스코스레이온이 주로 사용되었으나, 1950년대 중반부터는 나일론 등의 합성섬유가 사용되고 있다. A non-woven fabric is a coating material, which is made of felt by arranging the fibers in parallel or in an opposite direction without a woven fabric process and bonding them with a synthetic resin adhesive. Cotton and viscose rayon were mainly used for this, but synthetic fibers such as nylon have been used since the mid-1950s.

여기서 단섬유 형성단계는 폴리프로필렌과 폴리에틸렌을 이용하여 부직포를 형성할 원재료를 제조하는 단계로, 통상 베일(bale)의 상태로 제조된다.Here, the short fiber forming step is to prepare a raw material for forming a nonwoven fabric using polypropylene and polyethylene, and is usually manufactured in a bale state.

전술한 단섬유 형성단계에서 형성되는 단섬유는 폴리프로필렌과 폴리에틸렌 으로 이루어지되, 전술한 폴리에틸렌은 폴리프로필렌의 표면에 피막되어 형성된다.The short fibers formed in the above-described short fiber forming step are made of polypropylene and polyethylene, and the aforementioned polyethylene is formed by coating a surface of the polypropylene.

이때 전술한 폴리에틸렌은 추후에 설명될 1차 롤링과정에서 융해되어 부직포의 표면을 이루게 되는 역할을 하며, 폴리에틸렌에 비해 융점이 높은 폴리프로필렌은 1차 롤링과정에서 융해되지 않고 융해된 폴리에틸렌의 내부에 형성되게 된다.At this time, the above-mentioned polyethylene is fused in the first rolling process to be described later to form a surface of the nonwoven fabric, and polypropylene having a higher melting point than the polyethylene is formed in the molten polyethylene without melting in the first rolling process. Will be.

이러한 단섬유는 45중량% 내지 55중량%의 폴리프로필렌과 45중량% 내지 55중량%의 폴리에틸렌으로 이루어지되 굵기가 1denier 내지 3denier이고, 길이가 36mm 내지 40mm인 것이 바람직하다.Such short fibers are composed of 45% by weight to 55% by weight of polypropylene and 45% by weight to 55% by weight of polyethylene, preferably 1denier to 3denier, and preferably 36mm to 40mm in length.

The second rolling step is a step of re-pressing the nonwoven fabric formed in the aforementioned first rolling step through a roller to form a uniform surface. to be.

이때, 2차 롤링단계에서 사용되는 롤러는 카렌더롤러인 것으로 하며, 이 단계를 통해 부직포의 두께를 일정하게 하고 표면에 형성되어 있는 기모를 압착시켜 제거하게 된다.At this time, the roller used in the secondary rolling step is to be a calender roller, and through this step the thickness of the nonwoven fabric is made constant and the brush formed on the surface is compressed and removed.

또한, 2차 롤링단계를 거친 후, 전술한 1차 롤링단계와 마찬가지로 표면처리된 부직포를 2차 권취단계를 통해 권취하여 보관할 수 있다.In addition, after the second rolling step, the surface-treated nonwoven fabric may be wound and stored through the second winding step similarly to the above-described first rolling step.

이하에는, 본 발명의 바람직한 일 실시예에 따른 건축내장재용 부직포의 제조방법의 전체적인 제조과정에 대해 설명하면 다음과 같다.Hereinafter, the overall manufacturing process of the manufacturing method of the nonwoven fabric for building interior materials according to an embodiment of the present invention will be described.

먼저 단섬유 형성단계에서는 50중량%의 폴리프로필렌과 50중량%의 폴리에틸렌으로 이루어진 베일 형태의 단섬유를 형성하는데, 그 굵기는 2denier이고, 길이가 38mm 인 것으로 한다.First, the short fiber forming step forms a bale-like short fiber composed of 50% by weight of polypropylene and 50% by weight of polyethylene, the thickness of which is 2denier and the length is 38mm.

그런 다음, 개섬단계에서는 베일 형태의 단섬유를 잘 풀어서 카드기 내에 투입하여 단섬유 하나하나를 완전하게 개섬한다.Then, in the opening step, the bale-like short fibers are well unwrapped and introduced into a carding machine to completely open each single fiber.

그런 다음, 성형운반단계에서는 완전히 개섬된 단섬유를 일정한 두께 및 폭으로 형성되도록 성형하면서 다음단계인 1차 롤링단계로 유도한다.Then, in the molding conveying step, the fully opened short fibers are formed to have a predetermined thickness and width, leading to the next step, the first rolling step.

그런 다음, 1차 롤링단계에서는 130℃로 가열된 가열롤러를 통해 단섬유를 압착하여 부직포를 형성하는데, 이때 폴리에틸렌은 융해되어 부직포의 표면을 형성하고 폴리프로필렌은 융해된 폴리에틸렌의 내부에 위치하게 된다.Then, in the first rolling step, short fibers are pressed through a heating roller heated to 130 ° C. to form a nonwoven fabric, wherein the polyethylene is melted to form a surface of the nonwoven fabric, and the polypropylene is positioned inside the molten polyethylene. .

그런 다음, 2차 롤링단계에서는 카렌더롤러를 통해 부직포의 두께를 일정하게 하고 표면에 형성되어 있는 기모를 압착시켜 제거하게 된다.Then, in the second rolling step, the thickness of the nonwoven fabric is constant through the calender roller, and the brush formed on the surface is compressed to remove the compressed fabric.

2차 롤링단계를 거쳐 형성된 부직포는 건축 내장재로 사용되는 복합단열재의 일면에는 벽지 및 타일과 같은 마감재를 바로 시공할 수 있도록 부착된다.The nonwoven fabric formed through the second rolling step is attached to one surface of the composite insulation used as the building interior material so that finishing materials such as wallpaper and tile can be immediately installed.

이때, 복합단열재의 일면에 부착되고 단섬유로 이루어진 부직포는 그 표면이 폴리에틸렌으로 형성됨에 따라 여타의 건축내장재와 열융착이 용이할 뿐만 아니라, 친수성이 뛰어나 수성페인트 및 수성접착제와의 반응이 우수하다.At this time, the non-woven fabric made of short fibers attached to one surface of the composite insulation material is not only easy to heat fusion with other building interior materials as the surface is formed of polyethylene, but also has excellent hydrophilicity and excellent reaction with an aqueous paint and an aqueous adhesive agent. .

또한, 2차 롤링과정을 통해 직립된 기모가 제거되어 페인트 작업시 섬모의 직립 또는 뭉침현상이 일어나지 않게 된다.In addition, the brushed upright through the second rolling process is removed so that the upright or agglomeration of the cilia does not occur during the paint work.

이하에는, 본 발명의 바람직한 일 실시예에 따른 건축내장재용 부직포의 제조방법에 의해 제조된 부직포가 복합단열재의 일면에 부착된 모습이 종래기술에 따른 부직포가 복합단열재의 일면에 부착된 모습과 비교되어 도시된다.Hereinafter, the non-woven fabric prepared by the method of manufacturing a nonwoven fabric for building interior materials according to a preferred embodiment of the present invention is attached to one side of the composite insulation material compared with the non-woven fabric according to the prior art attached to one surface of the composite insulation material. Is shown.
