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.
