Abstract

PURPOSE: To increase the surface area of fibers and the amount of chelating functional groups to be introduced, by calcining ultra-fine polyvinyl alcohol fibers in the presence of a dehydration catalyst under specific conditions.
CONSTITUTION: Ultra-fine polyvinyl alcohol fibers having a filament diameter≤1μ are calcined in the presence of a dehydration catalyst, preferably ammonium polyphosphate of the formula (n is 10W400) at 80W250°C for 10W180min to give ultra-fine fibers with a weight loss of 5W25%. Chelating functional groups, e.g. mercapto groups, are introduced to form the objective fibers. For example, an aqueous solution of (A) completely saponified polyvinyl alcohol having an average polymerization degree of 800W3,000, and (B) an amorphous polymer, e.g. polyethylene oxide, is dry spun and rinsed with water to remove the polymer (B).
