Abstract

PURPOSE: After polycondensation reaction between terephthalic acid and glycol in the presence of a specific phosphorus compound and a metal compound, melt spinning is effected and the resultant fiber is partially eluted with an aqueous alkali solution to produce hollow fiber of high water and moisture-absorbing properties, becaused of its partially through pores.
CONSTITUTION: The polycondensation reaction between difunctional carboxylic acids mainly consisting of terephthalic acid or their ester-forming derivatives and alkylene glycols of 2W6 carbon atoms or their ester-forming derivatives is conducted in the presence of a phosphorus compound of the formula (R is monovalent organic group; X is hydroxyl, alkoxy, monovalent organic group; Y is hydroxyl, alkoxy; n is 0, 1) such as trimethyl phosphate and 1.0W2.2 equivalent amount, per mole of the phosphorus compound, of a metal compound such as sodium acetate and the polymer is melt spun into hollow fiber. The resultant fiber is treated with an aqueous alkali solution to elute 5W30wt% of the fiber, thus producing hollow fiber having pores along the fiber axis, a part of which opens through from the outside surface to the hollow surface.
