Abstract
A fiber is prepared by melt extruding a composition including specific amounts of a polyamide and a polyphenylene ether along with a compatabilizer. Particular combinations produce fibers having a desirable combination of good tenacity and low denier per fiber. Compared to a fiber prepared from polyamide alone, the present fiber exhibits improved heat resistance and flame resistance.
