Carboxy-terminated poly(oxyethylenes) (PEO-acid) with number-average molecular weights M(n) = 8 400, 3 300, and 1 000 were used for antielectrostatic modification of poly(ethylene terephthalate) (PET). The blend PET fibers containing 2.0 and 5.0 wt.-% of PEO-acids were melt-spun at 285-degrees-C with an ordinary extruder and then drawn about 4.5-fold at 80-degrees-C. The processabilities of spinning and drawing were excellent at higher molecular weights of PEO-acid. The anti-electrostatic properties of the blend fibers became also improved with increasing molecular weight of PEO-acid. Since little ester interchange reaction took place between PET and PEO-acid during melt-spinning, the blend fibers could retain almost the same mechanical properties as the original PET fiber.
