Abstract

La présente invention concerne un appareil de filage permettant de produire des nanofibres composites à deux composants, ledit appareil de filage comprenant : (i) un tube de filage (T) doté d'un corps de tube de filage (Ta) de forme cylindrique ou conique, d'une partie creuse tubulaire et polygonale (Tb) formée, le long de la direction de la longueur du corps de tube de filage (Ta), à l'intérieur du corps de tube de filage (Ta) et de buses (Tc) installées dans des positions respectives faisant face aux zones de sommet respectives de la partie creuse tubulaire et polygonale (Tb), le long de la direction de la longueur du corps de tube de filage (Ta), d'un point situé à une distance prédéfinie (h) vers le bas à partir de la surface supérieure du corps de tube de filage (Ta) jusqu'à la surface inférieure du corps de tube de filage (Ta), le tube de filage (T) ayant une structure dans laquelle chacune des buses (Tc) est installée de façon à former une paire avec et à faire face à une zone de sommet sélectionnée parmi les zones de sommet de la partie creuse tubulaire et polygonale (Tb) et dans laquelle les zones de sommet de la partie creuse tubulaire et polygonale (Tb) sont en contact avec la surface circonférentielle externe du corps de tube de filage (Ta) ; et (ii) un tube de distribution de solution de filage (1) relié au tube de filage (T) et possédant une forme cylindrique ou conique avec une structure tubulaire double. La présente invention utilise simultanément une force électrostatique et une force centrifuge, ce qui permet de produire des nanofibres composites à deux composants avec une productivité élevée (volume de décharge), de faciliter la volatilisation et la récupération des solvants, d'empêcher efficacement un phénomène (chute) dans lequel une solution de filage tombe sur un collecteur dans un état de solution et non dans un état fibreux, permettant ainsi d'améliorer la qualité d'une bande de nanofibres composites à deux composants.
