The modified polyester fiber comprises the component of alkoxylated 2-methyl-1,3-propanediol and has the properties of easy dyeability at low temperatures and good colorfastness to laundering. The modified polyester fiber can be produced by undergoing a polymerization reaction of alkoxylated 2-methyl-1,3-propanediol, alkanediol, and terephthalic acid or an alkyl ester thereof, and then spinning. The modified polyester fiber can be dyed at low temperature and has excellent dyeability and colorfastness to laundering.
