ABSTRACT:
A nonwoven mat of polyolefin fiber is contacted with a gaseous sulfur dioxide-chlorine mixture to sulfo-chlorinate the surface of the polyolefin fibers to a relatively high sulfur content and then preferably treated with an amine, either after compacting the mat or before compacting the mat to form a structure suitable as a battery separator. The mat can be used for other structures besides battery separators. And it can be separated into individually wettable staple fibers before compaction, i.e. individual separate fibers which are wettable.
