Abstract

PURPOSE: To obtain a polyester capable of giving fibers having specific micropores and improved water and moisture absorption properties, by adding a specific amount of a metallic salt of a sulfonic acid as a solution in a mixed solvent of glycol with water of specific composition to the reaction system.
CONSTITUTION: (A) An acid component consisting of terephthalic acid essentially and (B) an alcoholic component consisting of a 2W6C alkylene glycol, preferably ethylene glycol essentially are subjected to the ester interchange reaction, and (C) a metallic salt of a sulfonic acid expressed by the formula (Ar is aromatic group; R is ester-forming functional group; M and M' are metal; m is an integer 0W4; n is an integer 1W5; m+n is an integer 1W5), preferably disodium 3- carbomethoxybenzenesulfonate-5-carboxylate, in an amount to give 0.1W25mol% based on the component (A) as a solution in a mixed solvent of the glycol with water at a weight ratio of the water to the glycol of (5/95)W(80/20) in a concentration of 5W40wt% based on the solution is added to the reaction system to carry out the polycondensation reaction.
