ABSTRACT:
The present invention relates to a process for obtaining PAI fibres by spinning PAI in solution and to the fibres thus obtained. They are obtained by dry or wet spinning into dimethylalkyleneurea followed by removal of the solvent and overdrawing at high temperature. The yarns and fibres obtained are produced from PAI based on tolylene or meta-phenylene diisocyanate, and on an aromatic acid anhydride and/or an aromatic dianhydride, and optionally on one or a number of diacid compounds. They exhibit an outstanding thermomechanical behavior and make it possible to gain access to very low linear densities.
