<p>Polyamide fibres, filaments, foils contain, as matting agent, TiO2 of the rutile type contg. divalent Mn. The Mn is present in amount 0.1 to 60 wt. %. The Mn-ions are firmly bonded to the surface of the TiO2 particles by diphosphate and are adsorbed as Mn-diphosphate. The TiO2 contg. light-stabiliser is added before, during or after polymerisation or the polymer is admixed with the TiO2 before spinning.</p> |
