Abstract
PURPOSE: To obtain the titled filaments having improved hydrolytic and heat resistance, by adding an aromatic monocarbodiimide compound to a polyester resin and further a specific amount of phosphorus thereto, and melt spinning the resultant mixture to reduce the terminal carboxyl group concentration.
CONSTITUTION: (B) An aromatic monocarbodiimide compound, e.g. 2,6,2',6'- tetraisopropyl-diphenylcarbodiimide, in an amount of 10W100mol/106g based on a component (A) is added to the component (A) a polyester resin having an intrinsic viscosity ≥0.6, a terminal carboxyl group content ≥30eq/106g and phosphorus in a content ≤50ppm expressed in terms of phosphorus atoms and in the range of the formula (P is mol% of phosphorus atoms based on the dibasic acid constituting the polyester; M is a metal or metals in the polyester resin and mol% of one or more metallic atoms selected from Groups II, VII and VIII and the third and the fourth periods in the periodic table based on the dibasic acid constituting the polyester), and the resultant mixture in then melt spun to give the aimed filaments.
