Abstract (en)
[origin: EP1199399A1] The polytrimethylene terephthalate-based polyester yarn, which has excellent smoothness, heat resistance, collectability and anti-electricity, scarcely generates fluffs and broken yarn, and can stably be subjected to false-twisting, is a polyester yarn whose 80 % or more by weight is formed from polytrimethylene terephthalate, which has a birefringence of 0.03 to 0.08, an elongation of 30 to 180%, an elastic recovery of 30 to 100% at 10% elongation, and to whose surface a treating agent, containing an ether-ester compound (the component a) represented by the following formula in an amount of 50 to 80 % by weight and a polyether compound (the component b) having a molecular weight of 10,000or more in an amount of 2 to 20 % by weight, is stuck in an amount of 0.2 to 1.0 % by weight. R1 OCO-(A)X-(CH2)Z-(A)Y-COOR2 Äwherein, R1 and R2 are each an alkyl group having 7 to 21 carbon atoms, A is an oxyalkylene group having 2 to 4 carbon atoms, X and Y are each an integer of not less than 0, provided that (X + Y) is an integer of 1 to 20, and Z is an integer of 3 to 12Ü.
