Patent

CA 2687407

The invention relates to a method for producing a spinning solution for producing a polymer fiber, particularly a p-aramid fiber, the polymer being blended with a solvent, mixed, melted, homogenized, and degassed and then discharged, liquid sulfuric acid being used as the solvent and at least the mixing, homogenization, and degassing taking place in a preferably continuously operated single or double cell reactor (1).

L'invention concerne un procédé de fabrication d'une solution de filage pour la fabrication d'une fibre polymère, en particulier une fibre de p-aramide, le polymère étant déplacé, mélangé, fondu, homogénéisé et dégazé puis distribué avec un solvant. De l'acide sulfurique liquide doit être utilisé comme solvant et au moins le mélange, l'homogénéisation et le dégazage doivent avoir lieu dans un réacteur à un ou deux arbres (1) fonctionnant de préférence en continu.
