Abstract (en)
[origin: EP0360708A1] The present invention relates to heat-resistant filaments, yarns and fibres based on polyamide-imide. They have a polydispersity index I </= 2.2, a tenacity at break >/= 45 cN/tex, a Young's modulus >/= 3.8 GPa, an elongation </= 25%, a colour defined by the luminance gamma > 25%, the whiteness W < 30 and the yellowing index YI > 170. In addition, they have very good stability to light, quantified by the retention of the mechanical characteristics. They find wide application in work and protective clothing.
