摘要

Producing high strength flame-retardant cellulose filament regenerated fibers, comprises adding phosphorus- and sulfur-containing flame retardant agent to viscose before spinning into fibers, where the phosphorus containing agent is 2,2'-oxy-bis[5,5-dimethyl-1,3,2-dioxaphosphorinane]2,2'-disulfide. The viscose comprises the viscose that is used for the production of Super cord(RTM: Industrial braid rope).
