PURPOSE:The titled yarn having improved durability of antistatic properties, obtained by copolymerizing polyester with a small amount of an alkali metal sulfonate group-containing compound, adding a small amount of a specific metal compound to the copolymer to give a composition, spinning it. CONSTITUTION:Polyester is copolymerized with (A) 0.5-3mol% based on total acid component of an alkali metal sulfonate group-containing compound (e.g., 5-sodium sulfoisophthalic acid, etc.), and blended with (B) (15-40)X10<-4>mol one or more of metal compounds (e.g., acetate, etc.) of Mg, Mn, and Zn based on 1mol acid component of polyester, and, if necessary, (C) preferably 1-10wt% polyalkylene glycol to give a composition, which is spun by a conventional procedure, to give the desired yarn. EFFECT:Having improved workability in spinning, drawing, etc.
