Definitions

  • Comparative Examples 1 and 2 show that viscose and cupro filaments, even without added flame retardant agent do show completely unsatisfactory properties.
  • FR Lyocell filaments do display highly satisfactory properties, even though mechanical properties are somewhat lower, compared to Comparative Example 3, i.e. the non FR Lyocell filament.
  • the properties for the FR Lyocell filament in accordance with the present invention are significantly improved, as compared to the non FR viscose and cupro filaments.
  • the comparative examples using other types of cellulose filaments do suffer from a great imbalance of mechanical properties, so that no dimensionally stable products can be prepared for these filaments.
  • the flame retardant filaments of the present invention in addition to showing highly satisfactory flame retardant properties, also do show a great balance of mechanical properties.
