HIGH-STRENGTH POLYESTER FIBER

摘要

PROBLEM TO BE SOLVED: To provide a high-strength polyester fiber having a good color and suppressed generation of fluffs caused by foreign materials on a spinneret. SOLUTION: The high-strength polyester fiber is composed of a polyester polymer produced by the polycondensation of an aromatic dicarboxylate ester in the presence of a catalyst containing a specific titanium compound component and a phosphorus compound. The molar ratio of phosphorus element to titanium metal element is 1-15, the sum of the above elements is 10-100 m-mol% in one repeating unit and the fiber strength is≥7 cN/dtex. The woven or knit fabric is composed of the polyester fiber. COPYRIGHT: (C)2004,JPO&NCIPI
