ABSTRACT:
A flame-retardant filament-forming copolyester resin of at least 75 mol % of ethylene-2,6-naphthalene dicarboxylate units and at least 5 mol % up to 25 mol % of alkylene-2,5-dibromoterephthalate units is disclosed herein. In addition, fibers of the above flame-retardant copolyester resin and flame-retardant cellulosic fibers are blended together to provide flame-retardant yarns and fabrics of excellent physical properties.
