Abstract

PURPOSE: To obtain the titled fibers having specific micropores and improved dry feeling, by incorporating a specific metallic salt of a sulfonic acid with a material in any step of synthesizing a polyester from terephthalic acid, etc. and a glycol, melt spinning the resultant polyester, and removing the metallic salt from the resultant fibers.
CONSTITUTION: A bifunctional carboxylic acid containing terphthalic acid essentially or an ester-forming derivative is reacted with a glycol containing a 2W6C alkylene glycol essentially or an ester-forming derivative thereof to syntheize a polyester, which is then melt spun to give solid fibers. In the process, 0.1W25mol%, based on the bifunctional carboxylic acid, metallic salt of a sulfonic acid expressed by the formula (Ar is aromatic ring; R is ester-forming functional group; M and M' are metal; m is 0W4; n is 1W5; m+n is 1W5) is incorporated with a material in any step before the completion of the melt spinning. The resultant fibers are then trated with an aqueous solution of an alkali to remove at least a part of the compound.
