Abstract
PURPOSE: To obtain a polyester providing fibers having micropores communication from the inside to the surface and being excellent in water absorption, etc., by adding two specified compounds having a sulfonic group to the reaction system in the production of a polyester.
CONSTITUTION: In the production of a polyester by reacting a terephthalic acid- based difunctional carboxylic acid with a 2W6C alkylene glycol, the purpose polyester is obtained by premixing (A) 0.1W25mol%, based on difunctional carboxylic acid component, compound represented by formulaI, wherein Ar is an aromatic ring, R is an ester-forming functional group, M and M' are each a metal, m is 0W4, n is 1W5 and m+n=1W5, with (B) 5W500mol%, based on component A, compound represented by formula II, wherein Z is an aromatic ring, an aliphatic hydrocarbon group, X is an ester-forming functional group or H and M" is a metal, and adding the mixture to the reaction system.
