Abstract

Abstract The invention relates to a thread with a proportion of a basic-dyeable, texturized polyester filament which contains a metal sulphonate containing the structural unit ##STR1## where M is equal to Na or K and a compound A containing structural units --(CH 2 ) y -- and/or --O--(C x .sbsb.1 H 2x .sbsb.1 O) y .sbsb.1 -- where x 1 ≧2, y≧20 and x 1 y 1 ≧20. The basic-dyeable polyester filament contains 1.0 to 5.0 mol % of metal sulphonate units and between 0.5 and 12% by weight of compound A.
