An antistatic poly(1,3-trimethylene terephthalate)(PTT)was synthesized from purified terephthalic acid(PTA),1,3-propanediol(PDO)and antistatic agent via direct esterification.The antistatic PTI" DTY of 165 dtex/36 f was prepared from the resulted PTI" chip via high-speed spinning process subsequent to solid-state polycondensation.The results showed that thePTT with fairly good spinnability and antistatic behavior can be obtained by adding 1.5%-2.5%antistatic agent by mass fraction at 20 min before the accomplishment of polymerization reaction and exposing to solid-state polycondensation under vacuum till the FIT chip reached the intrinsic viscosity of 0.950 dL/g.The obtained PTT DTY had good handle feeling and the fabric exhibited the surface resistance up to 10~9-10~(10) Ω.
