摘要： Disclosed is an easy dyeable polyester fiber. Consisting of 60-95 mol % of polyethylene terephthalate and 5-40 mol % of polytrimethylene terephthalate, the polyester fiber of the present invention is prepared through copolymerization or through the ester interchange in such a way that it ranges, in melting point from 230° C. to 250° C., in birefringence from 100 to 190×10−3, and in boil-water shrinkage, from 8 to 25. Using disperse dyes, the polyester fiber can be dyed in deep shades at as low as or lower than 100° C. under atmospheric pressure. Thus, the polyester fiber of the present invention is can be used in mixture with thermal resistance-insufficient fibers such as spandex without causing yellowing therein. Also, it does not allow spots in the dyeing to appear thereon upon after-treatment, and in addition shows good fastness to washing, water, sublimation and friction.
