ABSTRACT:
A deep-dyeable polyester fiber of soft hand comprising recurring units consisting mainly of ethylene terephthalate and --SO.sub.3 M groups in which M is an alkali metal, and having a degree of crystallinity .chi..sub..rho. of from 30 to 55%, a degree of orientation .DELTA.n of from 0.06 to 0.12 and .chi..sub..rho. /.DELTA.n of from 350 to 550. The fiber can be produced by heat treating a melt spun, slightly oriented filament under relaxation and then drawing the heat treated filament at a low temperature.
