Process for producing high-performance polymer fibers |
摘要 |
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. |

1. A process for the preparation of polymer filaments having a high tensile strength and modulus comprising:
a) extrusion of a solution of a solvent and linear high-molecular weight polymer; b) spinning and quenching of filaments formed in step (a); and c) stretching the as-spun filaments under contact with steam thereby removing the solvent from the filaments. |
