ABSTRACT:
A method for producing polyester fibers having excellent dyeability with basic dyes or disperse dyes, which comprises melt-spinning a polyester comprising predominantly (at least 80% by mol) repeating units of ethylene terephthalate and containing 0.5% by mol or more, preferably 1.5 to 5% by mol of an ester unit derived from a dicarboxylic acid or diol containing at least one metal sulfonate group under the condition of being highly oriented so as to give filaments having a birefringence (.DELTA.n) of 0.015 to 0.100 and drawing the resulting filaments at a fixed temperature and in a fixed draw ratio, and the polyester fibers which can be dyed with basic dyes or disperse dyes at a temperature of less than 100.degree. C at a sufficiently high dye adsorption rate to give dyed fibers.
