A continuous, carrierless dyeable polyester fiber and the process for its preparation is set forth. The fiber is produced from a polymer obtained by producing a melt blend system comprising a homogenous blend of (a) not less than 78 percent by weight of poly(ethylene terephthalate) copolymerized with major amounts of a dicarboxylic acid other than terephthalic acid and (b) minor amounts, that is to say, quantities less than that of said dicarboxylic acid, of a homopolymer selected from the group consisting of poly(trimethylene terephthalate), poly(tetramethylene terephthalate), poly(pentamethylene terephthalate), poly(hexamethylene terephthalate), poly(heptamethylene terephthalate), poly(octamethylene terephthalate), poly(nonamethylene terephthalate) and poly(decamethylene terephthalate). |
