By reducing the amount of antimony element and slowly increasing the degree of polymerization of the polyester, it was possible to suppress thickening during polymerization.

- the synthetic fiber obtained by the present invention has a sufficient hygroscopicity to obtain comfortable wearing, and has a dry touch feeling, high color fastness and light fastness.
- the synthetic fibers of the present invention are suitable for underwear, shirts, blouses, middle garments, sportswear, slacks, outer garments, linings, curtains, wallpapers, and even for bedding such as garments, shoes, tonkaba, and wadding. It is extremely practical.
