Abstract

La présente invention concerne un procédé de préparation de brins fibrillés plexifilamentaires d'un polymère synthétique fibrogène, comprenant la production d'un fluide de filage et le filage éclair du fluide de filage pour former des brins fibrillés plexifilamentaires du polymère synthétique fibrogène. Le fluide de filage comprend essentiellement (a) 5 à 30 % en poids d'un polymère synthétique fibrogène, (b) un premier agent de filage choisi parmi le groupe comprenant des hydrocarbures ayant de 4 à 7 atomes de carbone, et des composés chlorés, bromés et fluorés, et (c) un co-agent de filage choisi parmi le groupe comprenant essentiellement les composés organiques fluorés contenant 4 à 8 atomes de carbone et une double liaison, et ayant un point d'ébullition à pression atmosphérique inférieur à 100 ·C. Le co-agent de filage est présent dans le fluide de filage en quantité suffisante pour faire augmenter la pression de point de trouble du fluide de filage d'au moins 50 livres par pouce-carré (345 kPa). Cette invention concerne également un fluide de filage utilisé dans le procédé de l'invention.
