PROBLEM TO BE SOLVED: To provide a knit of a polyester fiber produceable while causing a very small amount of a material attached to a spinneret even after a long-time continuous spinning through the spinneret, and having an elongation the dispersion of which is reduced to the utmost, and suitably usable for applications as a construction material and an industrial material. SOLUTION: The knit is composed of a polyester fiber, and the polyester is the polymer obtained by polycondensing an aromatic dicarboxylate in the presence of a catalyst containing a specific titanium compound and phosphorus compound. The molar ratio of the content of phosphorus element to the content of titanium element is 1-15, and the content of the total thereof per repeating unit is 10-100 mmol%. COPYRIGHT: (C)2004,JPO&NCIPI
