ABSTRACT:
An undrawn polyester yarn comprising 0.2 to 10% by weight of a polymer having a recurring unit structure represented by the following formula (1): ##STR1## wherein R.sub.1 and R.sub.2 stand for substituents consisting of optional atoms selected from C, H, N, O, S, P and halogen atoms, with the proviso that the sum of the molecular weights of R.sub.1 and R.sub.2 is equal to or more than 40, and n is a positive integer, and having a molecular weight equal to or more than 1000, the elongation increase ratio (I) of the undrawn polyester yarn, represented by the following formula (2), being equal to or more than 8%: ##EQU1## wherein EL.sub.b stands for the residual elongation (%) of the undrawn yarn and EL.sub.o stands for the residual elongation (%) of a corresponding undrawn polyester yarn substantially free of the polymer represented by the formula (1).
