The polyester composite filament is composed of general polyester and copolymer polyester obtained by copolymerizing terephthalic acid(TPA), isophtalic acid(IPA), anhydrous phtalic acid(PAn) as acid components, and ethylene glycol as diol component. The molar ratio of the acid components of copolymer polyester is as follows. 0.6949= RA= 0.8519, 0.0689= RB= 0.1482, 4.75= RC= 9.50, where RA=(IPA+PAn)/TPA, RB=PAn/TPA, RC=IPA/PAn.
