Description

열선이 구비된 시트지의 제조방법
본 발명은 열선이 구비된 시트지의 제조방법에 관한 것으로서 보다 상세하게는 자동차용 의자에 설치하여 열원을 공급하도록 하는 열선을 간편하고 쉽게 원단의 일면에 니들링을 하지 않고 열선을 부착시켜 고정함으로써 열선의 파손을 방지하여 열전도의 품질을 향상시키고 보다 많은 열을 앞쪽으로 전달할 수 있도록 한 열선이 구비된 시트지의 제조방법에 관한 것이다.
최근에는 차량의 성능뿐만 아니라 소비자의 감성 및 승차감을 만족시키기 위해 다양한 종류의 편의장치들이 차량에 설치되는 것이다. 특히, 사계절의 온도변화가 뚜렷한 우리나라에서는 차량의 온도조절능력에 따라 소비자의 감성만족도가 달라지게 되는 것이다.
온도가 비교적 높은 여름철에는 냉방장치에 의해 차량의 실내온도를 낮추게 되도 온도가 비교적 낮은 겨울철에는 히터에 의해 차량의 실내온도를 낮추게 되는 것이다.
하지만, 최근에는 차량의 실내에서 작동되는 히터에 유해세균 및 오염물질들이 많이 포함되어 운전자 및 탑승자의 건강에 악영향을 끼칠 수 있다는 연구결과가 발표되면서 차량의 실내온도를 히터를 사용하여 높이기보다는 핸들이나 시트에 설치되는 열선을 작동시켜 운전자 및 탑승자의 신체를 직접 가열하여 차량 실내의 온도를 높이게 되는 것이다.
첨부도면 도 1에 도시된 바와 같이 종래의 자동차용 시트(200)에는 열선(400)이 설치되어 있으며 종래 열선(400)의 설치방법은 섬유재로 이루어진 고정원단(500)을 테이블 상의 틀에 고정한 후 상부에 위치하는 바늘대는 프레임 고정되어 있고 열선공급장치는 바늘대 옆쪽에 부착되어 틀이 이동하면서 1차적으로 바늘대가 실(300)을 고정하면 실(300)을 중심으로 열선(400)이 좌우 지그재그로 이동하면서 열선(400)을 고정하는 방식으로 결과적으로 볼 때는 실(300)이 열선(400)을 고정하는 것처럼 보였다.
하지만 열선(400)을 공급하는 열선공급장치와 바늘대 그리고 틀 세가지 움직임의 타이밍이 속도를 높일수록 정확도가 떨어져 바늘이 열선(400)을 가격하는 일이 발생하고 고정원단(500) 특성을 많이 타 신율이 큰 고정원단(500)에는 입력한 도면(디자인)과 실제 제품이 오차가 많이 발생하여 결국엔 발열의 편중이 발생하게 되어 화재가 발생할 수도 있었기 때문에 밀도가 높거나 텐션이 없는 소재만을 사용하였다.
뿐만 아니라 고정원단(500)을 고정하는 틀의 크기가 약 폭 1~1.5M, 너비 약 5~7M이고 틀의 가장자리를 따라 클립이나 공압으로 가압하는 장치가 원단을 고정하는 구조로 피스작업이 불가능하였다. 더욱이 지그재그 방식으로 틀을 흔들어주기 때문에 실제 열선(400)의 이동거리보다 약 2~3배의 이동거리를 가게 되어 작업속도가 현저히 낮았다.
상기와 같이 고정원단(500)에 금속사 이루어진 열선(400)을 고정할 때 바늘이 고정원단(500)을 관통하게 되는데 이때 바늘이 열선(400)을 가격하게 되어 열선(400)의 일부분이 단선되거나 또는 열선(400) 자체가 완전히 단선되는 일이 발생되어 시트지의 불량율이 높고 품질이 저하되는 문제점이 있다.
또한 열선(400) 내부 발열체가 아닌 피복에 찍힘이 발생하였을 때에도 당장 기능상의 문제는 없지만 향후 해당 부위에 지속적인 하중이 가해질 경우 꺾임을 유도하여 장기적으로 불량이 발생할 수도 있다.
또한 상기 고정원단(500)에 열선(400)이 실(300)에 의해 감기어져 고정되어 있기 때문에 열이 앞쪽으로 전달되지 않고 옆으로 새어나가 열 손실이 발생됨으로 에너지가 필요 이상으로 소모되는 문제점과 고정원단의 표면에서 열선이 돌출되고 실에 의해 고정되어 있어 미관이 미려하지 못하다는 단점도 있다. 종래에는 바느질장치(큘팅장치)에 의해 고정되기 때문에 작업시간이 길고 소음이 과다하게 발생되기 때문에 작업장 환경이 열악하다는 문제점도 있다.
상기한 종래 문제점을 감안하여 안출한 본 발명의 목적은 원단의 일면에 열선을 고정하는 코팅층을 도포하고 상기 코팅층에 열선의 부착 또는 일부가 매립되도록 함으로서 열선을 간편하고 쉽게 원단의 일면에 니들링을 하지 않고 열선을 부착시켜 고정함으로써 열선의 파손을 방지하여 열전도의 품질을 향상시키고 제품의 미관을 미려하게 유지할 수 있으며 열선을 간편하고 간단하게 원단에 고정할 수 있는 이점과 열선을 고정시키기 위해 이동하는 이동거리가 짧고 빠른 작업속도로 생산속도 향상과 피스 작업이 가능하여 생산수율을 높일 수 있는 이점이 있다.
상기 원단에 코팅층이 형성되어 있어 열이 원단에 흡수되지 않고 전방으로 방출되기 때문에 열전도의 효율이 증대되고 따라서 에너지 소모를 절감할 수 있고 열선보호지의 부착이 용이한 이점 등이 있는 열선이 구비된 시트지의 제조방법를 제공하는데 있다.
이러한 본 발명의 목적은 열선이 구비된 시트지의 제조방법에 있어서, 원단부재의 일면에 열선을 부착시키기 위한 열선부착코팅층을 도포시키는 코팅층형성단계와; 상기 열선부착코팅층의 형성 후 열선부착코팅층에 열선을 설치하는 열선공급단계와; 상기 열선부착코팅층의 상부에 열선을 고정하기 위한 열선보호지를 설치하는 열선보호지공급단계와; 상기 열선부착코팅층과 열선보호지를 가열 압착하여 부착시키는 부착단계 순으로 이루어지는 것을 특징으로 하는 열선이 구비된 시트지의 제조방법에 의하여 달성된다.
상기 코팅층형성단계 전 원단부재의 일면에 점착층과 이형지를 부착시키는 점착층형성단계를 더 포함하여 이루어지는 것을 특징으로 하는 열선이 구비된 시트지의 제조방법에 의하여 달성된다.
상기한 제조방법의 구현은 열선이 구비된 시트지에 있어서, 자동차 의자 또는 가구에 부착하기 위한 원단부재와; 상기 원단부재의 일면에 열선을 부착시키기 위한 열선부착코팅층과; 상기 열선부착코팅층에 적층되는 열선과; 상기 열선부착코팅층에 적층 및 부착되어 열선을 고정하는 열선보호지로 이루어진 것을 특징으로 하는 열선이 구비된 시트지에 의하여 달성된다.
상기 원단부재와 열선보호지는 부직포, 직포, 필름, 발포폼 중 어느 하나인 것을 특징을 하는 열선이 구비된 시트지에 의하여 달성된다.
상기 원단부재에는 자동차 의자 또는 가구에 부착이 용이하도록 점착층이 더 구비되어 이루어진 것을 특징으로 하는 열선이 구비된 시트지에 의하여 달성된다.
이와 같은 본 발명은 원단의 일면에 열선을 고정하는 코팅층을 도포하고 상기 코팅층에 열선의 부착 또는 일부가 매립되도록 함으로서 열선을 간편하고 쉽게 원단의 일면에 니들링을 하지 않고 열선을 부착시켜 고정함으로써 열선의 파손을 방지하여 열전도의 품질을 향상시키고 제품의 미관을 미려하게 유지할 수 있으며 열선을 간편하고 간단하게 원단에 고정할 수 있는 이점과 상기 원단에 코팅층이 형성되어 있어 열이 원단에 흡수되지 않고 전방으로 방출되기 때문에 열전도의 효율이 증대되고 따라서 에너지 소모를 절감할 수 있고 열선보호지의 부착이 용이한 이점 등이 있는 유용한 발명이다.
또 다른 효과로는 니들링에 비해 이동거리가 짧아 생산속도를 높일 수 있으며 원가 절감이 가능하며 롤이나 시트 상태가 아닌 피스작업이 가능하여 생산수율을 높일 수 있다.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.
첨부도면 도 2는 본 발명의 기술이 적용된 열선이 구비된 시트지의 제조방법을 보여주는 예시도로써 이에 따르면 본 발명은 먼저 테이블 상에 원단부재(10)를 고정 설치한 후 일면에 열선(30)을 부착시키기 위한 열선부착코팅층(20)을 도포시키는 코팅층형성단계(S100)를 실시한다.
이때 원단부재(10)를 고정하는 지그를 사용할 수도 있으며 또는 롤 혹은 시트 혹은 재단물(피스)로 형성되는 원단부재(10)를 에어로 흡착 고정시켜 배선 작업의 정확성을 높일 수 있다.
상기 원단부재(10)는 부직포, 직포, 필름, 발포폼, 종이 중 어느 하나를 사용할 수 있으며, 상기 열선부착코팅층(20)의 도포 공정은 접착력이 강하고 그 접착기가 오래 유지되는(OPEN-Time이 긴) 접착제를 일정한 두께를 갖도록 도포하며 그 도포량은 디자인의 난이도와 작업속도를 고려하여 결정한다.
상기 열선부착코팅층(20)의 종류는 열가소성, 열경화성, 습기경화형 등의 접착제 중 내열 온도가 높은 수지 중 어느 하나를 사용하며 열선의 설치 형태를 육안으로 쉽게 확인할 수 있도록 투명재질의 수지를 사용하는 것이 바람직하고, 또는 열선부착코팅층(20)를 형성시키는 다른 방법으로는 핫 멜트 접착 필름과 같이 필름형태로 이루어진 수지를 적층시켜 부착 형성시킬 수도 있다.
한편 상기와 같이 코팅층형성단계(S100)에 의해 열선부착코팅층(20)이 형성되면 접착제의 종류와 접착기의 유지력을 높이려는 등의 목적에 따라 열선부착코팅층(20)의 표면이 마치 젤과 같이 말랑말랑할 정도로 1차 건조시킬 수 있으며 상기 열선부착코팅층(20)의 건조 방법으로는 상온에서 자연 건조방법과 온도를 가열하면서 이동수단이 설치된 오븐 또는 챔버를 사용하여 건조하는 방법이 있다.
상기 열선부착코팅층(20)이 형성되면 열선부착코팅층(20)에 금속사로 이루어 열선(30)을 공급하는 헤드를 위치시키고 헤드를 이동시킴과 동시에 열선(30)이 열선부착코팅층(20)의 표면에 가접착상태가 되도록 공급하는 열선공급단계(S200)를 실시하면 열선은 열선부착코팅층(20)의 표면에 임시 부착된 상태로 설치된다.
한편 본 발명에서는 설명의 편의상 금속사로 이루어진 열선(30)을 사용하는 것으로 설명하고 있으나 도전성이 있는 액체 상태의 잉크나 원사(fiber)로 도선을 형성시켜 사용할 수도 있다.
종래에는 고정원단으로 잉크가 스며들어가 잉크 사용을 할 수 없었으나 본 발명에서는 코팅층형성단계(S100)에 의해 형성된 열선부착코팅층(20)에 프린트작업을 실시하여 열선을 형성시킬 수 있기 때문이다.
상기 열선(30) 공급이 완료되면 상기 열선부착코팅층(20)의 상부에 열선(30)을 고정하기 위한 열선보호지(40)를 설치하는 열선보호지공급단계(S300)를 실시한다. 상기 열선보호지(40)는 부직포, 직포, 필름, 종이 중 어느 하나를 사용할 수 있으며, 상기 열선부착코팅층(20)과 열선보호지(40)를 가열 압착하여 부착시키는 부착단계(400) 순으로 제조한다.
상기 열선보호지(40)를 상기 열선부착코팅층(20)과 가열 압착하여 부착할 때 상기 열선부착코팅층(20)과 열선보호지(40) 사이에 설치된 열선(30)이 가압되므로 열선부착코팅층(20)의 표면 상태와 가압력에 따라 첨부도면 도 3a 내지 도 3b에 도시된 바와 같이 열선부착코팅층(20)에 열선(30)의 부착 또는 일부가 매립되는 형태로 설치되면 따라서 열선(30)을 간편하고 쉽게 원단부재(10)의 일면에 실을 이용한 고정 방법 즉, 니들링을 하지 않고 열선(30)을 부착시켜 고정함으로써 열선(30)의 파손을 방지하여 열전도의 품질을 향상시키고 첨부도면 도 4에 도시된 바와 같이 제품의 미관을 미려하게 유지할 수 있다.
상기 열선부착코팅층(20)에 열선(30)의 부착 또는 일부가 매립되는 형태로 설치되면 코팅층의 최종 경화 과정을 거치게 되는데 자연 건조/경화방법과 온도를 가열하거나 습기 등을 공급하면서 이동수단이 설치된 오븐 또는 챔버 혹은 열이 공급되는 롤러 등을 사용하여 건조/경화시키는 방법이 있다.
상기와 같은 제조방법으로 제조된 시트지(1)의 구조는 첨부도면 도 3a 및 도 3b에 도시된 바와 같이 자동차 의자 또는 가구에 부착하기 위한 원단부재(10)의 일면에 열선을 부착시키기 위한 열선부착코팅층이 구비되며, 상기 열선부착코팅층에는 금속사로 이루어지며 플렉시블한 열선이 설치되며 상기 열선부착코팅층(20)에 적층 및 가부착된 열선보호지(40)를 적층한 후 가열 가압하여 열선부착코팅층(20)에 열선보호지(40)를 고정 설치한 구조이다.
본 발명은 열선(30)을 간편하고 간단하게 원단에 고정할 수 있는 이점과 상기 원단부재(10)에 열선부착코팅층(20)이 형성되어 있어 열이 원단부재(10)의 뒤로 방출되거나 원단부재(10)에 흡수되지 않고 전방으로 방출되기 때문에 열전도의 효율이 증대되고 따라서 에너지 소모를 절감할 수 있고 작업성이 우수하며 열선보호지의 부착이 용이한 이점 등이 있다.
첨부도면 도 5 및 도 6에 도시된 바와 같이 상기 코팅층형성단계(S100) 전 원단부재(10)의 일면에 점착층(50)과 이형지(60)를 부착시키는 점착층형성단계(S500)를 더 포함할 수도 있다.
상기 코팅층형성단계(S100) 전 원단부재(10)의 일면에 점착층(50)과 이형지(60)를 부착시키는 점착층형성단계(S500)를 실시하는 이유는 열선(30)이 구비된 본 발명의 시트지(1)를 자동차 의자 또는 가구 등에 부착하여 사용할 때 이형지만 제거하고 바로 부착하여 사용할 수 있는 편리하고 간편함을 제공 받을 수 있기 때문이다.
