Synthetic filaments, yarns and fibers based on polyamides - imides resistant to the heat and process to apply such filaments, yarns and fibers.

摘要

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.
