FLAME-RETARDANT POLYESTER MONO FIBER HAVING LOW MELTING POINT AND FIBER ASSEMBLY WITH EXCELLENT FLEXURAL STRENGTH AND FLEXURAL ELASTICITY USING SAME

摘要

The present invention relates to a flame-retardant polyester mono fiber having a low melting point, which produces a polyester resin having a low melting point by single spinning, wherein the polyester resin is produced by copolymerizing acidic components comprising dimethyl terephthalic acid or terephthalic acid, and dimethyl adipic acid or adipic acid, and diol components comprising 2-methyl-1,3-propanediol, 1,4-butanediol, and ethylene glycol, and in a copolymerization reaction, 4,000 to 6,000 ppm of a phosphorus flame retardant is added.;COPYRIGHT KIPO 2018
