traade on the basis of polyamide imide and method for their manufacture

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.
