Title (EN) PROCESS FOR PRODUCING HIGH-PERFORMANCE POLYMER FIBERS
(FR) PROCESSUS DE PRODUCTION DE FIBRES EN POLYMÈRE À HAUTES PERFORMANCES
Abstract: front page image
(EN)The present invention relates to a process for the preparation of polymer filaments having a high tensile strength and modulus by extrusion of a solution of a solvent and linear high-molecular weight polymer and subsequent spinning and quenching of the filaments thus formed, wherein after spinning and quenching the as-spun filaments are stretched under contact with steam for removing the solvent from filaments being stretched.
(FR)La présente invention concerne un processus pour la préparation de filaments en polymère présentant une résistance à la traction et un module élevés, comportant les étapes consistant à extruder une solution d'un solvant et d'un polymère linéaire à haut poids moléculaire puis à filer et à tremper les filaments ainsi formés, caractérisé en ce qu'après filage et trempe, les filaments issus de filage sont étirés en contact avec de la vapeur pour éliminer le solvant des filaments en cours d'étirage.
