Abstract

PURPOSE: To obtain a hollow fiber having improved water and moisture absorption, and durability thereof and a tensile strength fit for practical use, by treating a hollow polyester fiber comporising a copolyester of an organic sulfonic acid compound with an aqueous alkali.
CONSTITUTION: A blend of (A) 5W100pts.wt. a copolyester comprising preferably 2W16mol% an organic sulfonic acid compound, e.g. sodium 3,5-di(carbomethoxy) benzenesulfonate, of the formula (Z is trifunctional hydrocarbon group; M is H or metal; R1 is ester-forming functional group; R2 is H or ester-forming functional group) and (B) 100pts.wt. a polyester is melt spun to form a hollow fiber. The copolyester (A) is then partly removed by treating the fiber with an aqueous alkali to form micropores having a diameter of 0.001W5μ and a length of 50 times or less the diameter, which are partly communicated to the hollow part, scattered over the whole cross section and oriented in the fiber axis direction.
