description The present invention provides a method for producing polyester fibers which improves the defects that polyester fibers and the textiles thereof cannot be easily dyed. In such method, fibers could be dyed by using dispersed dyes at ambient pressure and a temperature of 100 DEG C. or less without adding carrying agents, and have good dyeability, high dyeing deepness and excellent color fastness. The textiles thereof have excellent dyeing retention. In the said method for producing fibers which could be easily dyed at low temperature, a composition consisting of 99.9 to 60% by weight of a first polyester component with a glass transition temperature (Tg) of greater than 20 DEG C. to 100 DEG C. and 0.1 to 40% by weight of a second polyester component with a glass transition temperature (Tg) of 20 DEG C. to -50 DEG C. is melted and spun to such polyester fibers.
