A polyester fiber is provided, which does not produce a huge amount of residues during its reducing process, and shows good appearance, feeling and superior characteristics as a fiber, such as a high tensile strength and elongation. Such polyester fiber is a conjugate fiber comprising a core spinned from a polyester containing an aromatic moiety and a skin layer surrounding the core, the skin layer spinned from an aliphatic polyester. The skin layer may be easily reduced by contacting it with an alkaline solution or an enzyme, to provide a reduced fiber with good appearance, feeling and superior characteristics as a fiber. |
