Abstract
An alkali resistant synthetic fiber and a sheeting obtained therefrom are disclosed, the fiber being comprised of a polymer mixture consisting of (A) from 15 to 80% by weight of polysulphone, (B) from 20 to 85% by weight of polyvinyl chloride having a degree of polymerization of from 800 to 2,500, and (C) up to 65% by weight of other vinyl polymer, each based on the total weight of the components (A), (B), and (C). The sheeting is excellent in alkali resistant in high temperatures and liquid retention and is therefore useful as industrial filters, battery separators, and industrial wipers.
