Zusammenfassung:PROBLEM TO BE SOLVED: To provide a polyester polymer excellent in dyeability and flame-retardant effect and having excellent process workability and mechanical properties, and to provide a fiber manufactured from the same. SOLUTION: A manufacturing method of a cationic dye-dyeable and flame-retardant polyester polymer comprises adding a metal sulfonate containing bishydroxyethyl isophthalate in amount of 0.01-5 mol% with respect to a dibasic acid component in a polymer in the course of polyester polymerization, incorporating a phosphorus flame retardant represented in the chemical formula in an amount of 500-40,000 ppm on the basis of phosphorus atom, and copolymerizing them. In the formula, R1and R2are each a 2-4C radical having a reactive group which can form an ester group; P is a phosphorus atom with a valence of 5; n is an integer of 1-5. COPYRIGHT: (C)2006,JPO&NCIPI
