Abstract: front page image
(EN)A device for spinning a side-by-side-type bicomponent complex nanofiber according to the present invention comprises: (i) a spinning tube (T) comprising a spinning tube body (Ta), a polygonal tube-shaped hollow portion (Tb), and solution separating plates (Tc); (ii) a first spinning solution reservoir (R1) positioned on the lower end of the spinning tube (T); (iii) a second spinning solution reservoir (R2) positioned on the lower end of the first spinning solution reservoir (R1); (iv) two or more first spinning solution supply tubes (H1) installed inside the first spinning solution reservoir (R1) so as to communicate with the polygonal tube-shaped hollow portion (Tb); and (v) two or more second spinning solution supply tubes (H2) installed inside the second spinning solution reservoir (R2) so as to communicate with the polygonal tube-shaped hollow portion (Tb). According to the present invention, solution separating plates (Tc) are installed inside the polygonal tube-shaped hollow portion (Tb) such that, just before spinning two types of spinning solutions through the corner part of the polygonal tube-shaped hollow portion (Tb) abutting the spinning tube body (Ta), intermixing of the spinning solutions is effectively prevented, making it easy to adjust the sectional shape of the manufactured side-by-side-type bicomponent complex nanofiber. In addition, the present invention simultaneously employs electrostatic force and centrifugal force and thus can manufacture a bicomponent complex nanofiber with a high productivity (amount of discharge); volatilization and recovery of the solvent are easy; and it is possible to effectively prevent the spinning solution from dropping onto the collector in a solution state rather than in a fiber state (drop phenomenon), thereby improving the quality of the bicomponent complex nanofiber web.
(FR)La présente invention concerne un dispositif permettant de filer une nanofibre complexe à deux composants de type côte à côte et qui comprend : (i) un tube de filage (T) comprenant un corps de tube de filage (Ta), une partie creuse en forme de tube polygonal (Tb), et des plaques de séparation de solution (Tc) ; (ii) un premier réservoir de solution de filage (R1) positionné sur l'extrémité inférieure du tube de filage (T) ; (iii) un second réservoir de solution de filage (R2) positionné sur l'extrémité inférieure du premier réservoir de solution de filage (R1) ; (iv) au moins deux premiers tubes d'alimentation en solution de filage (H1) installés à l'intérieur du premier réservoir de solution de filage (R1) de façon à communiquer avec la partie creuse en forme de tube polygonal (Tb) ; et (v) au moins deux seconds tubes d'alimentation en solution de filage (H2) installés à l'intérieur du second réservoir de solution de filage (R2) de façon à communiquer avec la partie creuse en forme de tube polygonal (Tb). Selon la présente invention, des plaques de séparation de solution (Tc) sont installées à l'intérieur de la partie creuse en forme de tube polygonal (Tb) de sorte que, juste avant le filage de deux types de solutions de filage à travers la partie d'angle de la partie creuse en forme de tube polygonal (Tb) venant en butée contre le corps de tube de filage (Ta), le mélange des solutions de filage soit efficacement empêché, ce qui facilite l'ajustement de la forme en coupe de la nanofibre complexe à deux composants de type côte à côte fabriquée. De plus, la présente invention utilise simultanément une force électrostatique et une force centrifuge et peut ainsi fabriquer une nanofibre complexe à deux composants présentant une productivité élevée (quantité de décharge) ; la volatilisation et la récupération du solvant sont faciles ; et il est possible d'empêcher efficacement la chute de la solution de filage sur le collecteur dans un état de solution plutôt que dans un état de fibre (phénomène de chute), ce qui permet d'améliorer la qualité de la bande de nanofibre complexe à deux composants.
(KO)본 발명의 사이드 바이 사이드형 2성분 복합 나노섬유의 방사장치는 (i) 방사튜브 본체(Ta), 다각형 튜브상 중공부(Tb) 및 용액분리판(Tc)들로 구성되는 방사튜브(T), (ii) 상기 방사튜브(T) 하단에 위치하는 제1방사용액 저장조(R1), (iii) 상기 제1방사용액 저장조(R1) 하단에 위치하는 제2방사용액 저장조(R2), (iv) 상기 제1방사용액 저장조(R1) 내부에 설치되어 다각형 튜브상 중공부(Tb)와 연통하고 있는 2개 이상의 제1방사용액 공급튜브(H1) 및 (v) 상기 제2방사용액 저장조(R2) 내부에 설치되어 다각형 튜브상 중공부(Tb)와 연통하고 있는 2개 이상의 제2방사용액 공급튜브(H2)를 포함한다. 본 발명은 상기 다각형 튜브상 중공부(Tb) 내에 용액 분리판(Tc)들이 설치되어 방사튜브 본체(Ta)와 맞닿아 있는 다각형 튜브상 중공부(Tb)의 모서리 부분을 통해 2종의 방사용액들을 방사하기 직전까지 방사용액들이 서로 혼합되는 것을 효과적으로 방지할 수 있어서 제조되는 사이드 바이 사이드형 2성분 복합 나노섬유의 단면 형태를 용이하게 조절할 수 있다. 또한, 본 발명은 정전기력과 원심력을 동시에 이용하기 때문에 2성분 복합 나노섬유를 높은 생산성(토출량)으로 제조할 수 있고, 용매 휘발 및 회수가 용이하고, 방사액이 섬유상이 아닌 용액상태로 컬렉터 상에 떨어지는 현상(드롭 현상)도 효과적으로 방지하여 2성분 복합 나노섬유 웹의 품질을 향상시키는 효과가 있다.
