Abstract

Hollow open-celled microporous polypropylene fibers having an oxygen gas permeability of at least 35 cc/cm<2>.min at 10 psi. are produced by melt spinning isotactic polypropylene at a temperature of at least 230 DEG C to form precursor hollow fibers having an average inner diameter of at least 140 microns, and an average inner diameter to average wall thickness ratio of from 8:1 to 40:1, annealing the precursor fibers at a temperature of 50 DEG C to not greater than 165 DEG C, and subsequently cold stretching, hot stretching and then heat setting the fibers. The resulting hollow microporous fibers exhibit an average inner diameter of at least 100 microns. [GB2041821A]
