Abstract
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.
