본 발명은 결합제가 함유되어 있는 셀룰로오스 섬유와 열가소성 섬유 또한 식물성 원료에서 나온 천연섬유로 구성된 부직물 조직에서 나온 고인장강도의 변형성 섬유를 유동역학적으로 제조하기 위한 방법에 관한 것으로, 이 방법에서 부직물 섬유 케이크(cake)는 실린더 내에서 혼합되고 부직물 조직은 상기 혼합물로부터 형성하며 그후 섬유매트를 만들기 위내 니들머신(needle machine)내에서 강화된다. 본 발명은 또한 이 방법으로 제조한 섬유매트를 사용하는 방법과 제조방법을 실행하기 위한 장치에 관한 것이다.
상술한 방법은 AT Patent 387,798에 공지된 바 있다. 이 공지방법의 장점에 따르면 부직물 조직이 실린더 내에서 혼합되고 그 결과 혼합물속에서 랩드럼상에 부직물조직이 더 많이 형성된다. 이점에서, 실린더에서 랩드럼까지의 직조되지 않은 섬유 조성물의 이동이 체계적으로 실행되지 않아 랩드럼상에 제조된 부직물 조직의 폭에 걸쳐 면적 유닛당 불균질한 대상물분포같이 섬유케이크가 불규칙하게된다. 덧붙여서, 합성수지가 함유된 목질섬유는 질량이 커서 펼쳐진 부직물 조직 밑면에 깔리게 되고 식물성 원료의 열가소성 또는 충전되지 않은 천연섬유가 레이드- 아웃(laid-out) 조직의 상층에 노출된다. 변화하는 층구조는 섬유매트 가공에 있어 불리하며 그 이유는 섬유매트 밑면의 결합제 함량이 지나치게 커서 점성이 더 커지기 때문이며 상층면은 결합제가 함유되어 있지 않다.
본 발명의 기본목적은 고인장강도를 가진 변형섬유가 폭방향으로 균일한 질량분포를 또한 균일한 혼합상태로서 결합제를 충전하거나 하지 않은 섬유를 함유하는 층구조를 갖는 것이다.
상기 목적은 또한 도면에서 도시한 바와 같이 부직물 조직 케이크(2,2')를 실린더(6,6')에 넣고 이 속에서 섬유케이크를 해체하며 그리하여 얻은 섬유 조성물(14,14')을 공기흐름으로 인해 완전히 혼합된다. 유동 프로파일은 공기도관(10,10')에 설치된 조절부(25,26)로 조정가능하며 또한 유동방향 하부에 연결된 벤튜리관(7,7')에 의해서도 조절된다. 균일한 질량분포를 갖고 또한 니들-펠트화 절차 뒤 압축장치(21,21')에 인도하여 고인장강도의 변형섬유매트(23,23')를 제조한다.
본 발명의 방법은 또한 제어부가 공기도관(10) 폭방향으로 분포된 다수의 조절부(25)를 포함하고 또한 공기흐름방향으로 소용돌이 곡선을 이루며 곡선배열형태로 조절가능한 다수의 조절부(26)를 포함한다. 덧붙여서, 본 발명은 도면에서 도시한 형태로 제조된 섬유매트의 유리한 용도에 관계하며 하나이상의 섬유매트(23,23')를 고압과 고온에서 압축하여 성형품을 만드는데 이용된다.
본 발명은 또한 도면에서와 같이 결합제를 충전한 셀룰로오스 섬유 또한 열가소성섬유와 식물성원료의 천연섬유로 구성된 부직물 조직으로부터 얻은 고인장강도의 변형 섬유매트를 유동-역학적으로 제조하는 장치에 관계하며 이 장치는 재질의 유동방향에서 잇달아서 플리싱(fleecing)머신(1), 압축로울러쌍(3,4), 인발 로울러쌍(5), 실린더(6), 공기도관(10), 벤튜리관(7), 확산기(13), 랩(lap)드럼(15), 수송로울러(16)(17) 또한 단위면적당 질량을 측정하는 기계(19), 니들 머신(20), 압축장치(21), 절단기(22) 또한 적층기(24)로 구성되며 이때 공기도관(10)은 하나이상의 조절밸브 형태로된 조절부(25)가 설치된 것으로서 팬에 의해 공기를 공급받는다.
덧붙여서, 본 발명은 결합제를 충전한 셀룰로오스 섬유와 열가소성 섬유, 또한 식물성 원료의 천연섬유로 구성된 부직물 조직으로부터 얻은 고인장 강도의 변형 섬유매트를 유동-역학적으로 제조하는 장치에 관계하며 이 장치는 재료의 유동방향으로 연속배열된 것으로서, 플리싱(fleecing)머신(1'), 압축 로울러쌍(3')(4'), 인발로울러쌍(5'), 실린더(6') 또한 팬(12')에 의해 공기를 공급받고 또한 공기흐름방향으로 소용돌이형 곡선을 이루며 이 형태로 조정할 수 있게된 하나이상의 조절부(26)가 설치된 공기도관(10'), 또한 벤튜리관(7'), 확산기(13'), 랩드럼(15'), 수송로울러(16')(17'), 단위면적당 질량을 측정하는 장치(19'), 니들 머신(20'), 압축장치(21'), 절단기(22')와 적층기(24')로 구성된 것을 특징으로 한다.
부직물 조직케이크(2,2')는 결합제 예컨대 듀로플라스틱, 열가소성물질 또는 탄성중합체등을 충전한 셀룰로오스 섬유와 폴리에스테르섬유, 폴리올레핀섬유, 폴리아미드섬유, 폴리아크릴 섬유, 아세트산 에틸렌비닐 섬유같은 열가소성 섬유와 아마 또는 황마섬유, 대마섬유와 셀룰로오스섬유 같은 천연섬유의 혼합물로부터 플리싱(fleecing)머신(1,1')를 이용하여 제조할 수 있다. 이 케이크는 압축로울러 (3,3', 4,4')로 압축시키고 인발로울러쌍(5,5')에 의해 실린더(6,6')로 인도한다. 실린더 표면에는 조직케이크(2,2')를 해체하는 바늘침 또는 톱니가 구비되어 있다. 공기흐름은 동축에서 구동되는 팬(12,12')에 의하여 공기도관(10,10')속에서 발생하며 흐름속도는 공기도관 폭방향으로 분포된 조절부(25,26)로 조정할 수 있다(제1,2도) 제1도에 따르면, 조절부는 밸브이다. 조절부(26)(제2도)는 공기흐름방향으로 소용돌이 곡선을 이루고 조정이 가능하다.
공기흐름속에 있는 섬유의 완전혼합은 흐름의 속도에 의존한다. 혼합작용은 축방향으로 ±30°로 회전함으로써 조절되는 벤튜리 관(7,7')을 설치하면 더 효과적이고 벤튜리관에는 폭이 다양한 웨브(8,8')가 설치되어 있다.
웨브(8,8') 사이에 생긴 슬릿(9,9')(제3도와 4도)에서 공기/섬유 혼합물의 흐름속도가 슬릿폭에 따라 증가하고 따라서 하부 확산기(13,13')속에서 섬유를 추가로 혼합할 수 있다. 덧붙여서, 이러한 흐름속도는 랩드럼(15,15')상에 섬유조성물(14,14')이 균일하게 펼쳐지도록 하는 삽질효과를 가져온다.
이렇게 형성된 새로운 부직물조직(18,18')은 수송로울러(16,16')와 (17,17')를 통하여 단위면적당 질량을 측정하는 장치(19,19')로 이동한다. 측정된 결과는 공지의 조직형성 방법을 사용할때 얻은 측정결과 보다 더 균일한 질량분포를 보여준다. 단위면적당 질량분포가 불만족스러운 경우 이들 분포는 하나이상의 조절부(25,26)를 조정하여 흐름속도를 변화시켜서 변형할 수 있다. 덧붙여서, 유동조건을 최적화하는 또 다른 수단은 벤튜리관(7,7')의 조절도이다.
부직물조직(18,18')은, 하부 니들머신(20,20') 내에서, 예컨대 폴리에스테르섬유, 폴리아미드섬유, 유리섬유나 황마 같은 섬유로 구성된 또 다른 부직물조직(27,27')에 니들펠트(needle-felted)화 되어 충분히 변형가능한 섬유매트(28,28')가 된다. 그러나 성형 프레스에서 후속처리하는 동안 섬유매트의 변형도를 더 크게 하기 위하여, 예컨대 캘린더나 벨트 프레스같은 압축장치(21,21')를 통해 인도한다. 섬유매트는 25 내지 150℃ 온도와 5 내지 50Kp/㎠의 비압으로 캘린더 로울러 사이에서 예비-압착되고 이에 따라 합성수지를 충전한 목질섬유가 인조섬유에 더 견고히 결합한다. 그 결과 섬유매트는 예컨대 압축성형 같은 가공 과정에서 더 큰 인장력을 흡수할 수 있고 따라서 고인장성을 갖추게 된다.
절단기(22,22') 통과후 예비 적층기(24,24')는 섬유매트(23,23') 위에 적층된다.
