Abstract (en)

A polyester fiber is disclosed, comprising a polyester obtained by copolymerizing a third component with poly(trimethylene terephthalate), wherein the third component is an ester-forming sulfonate compound in a copolymerizing ratio of from 0.5 to 5 mol%, the fiber has a peak temperature of loss tangent of from 85 to 115 DEG C, and the relationship between modulus Q (g/d) and elastic recovery R (%) of the fiber satisfies the following formula (1): 0.18Q/R0.45. This fiber can be dyed into a dark shade under atmospheric pressure and enables fast dyeing of a fabric using the fiber in composite with a stretch fiber represented by polyurethane elastic fiber or a fiber material having low heat resistance such as wool silk and acetate fiber. The composite fabric can be dyed under atmospheric pressure, therefore, the physical properties of fiber having low heat resistance used in combination is not impaired during the dyeing process. The polyester fiber of the present invention can be treated for caustic reduction, therefore, a fiber having highly soft and dry touch and dyeability into brilliant color can be obtained.
