    摘要: Improved polybenzoxazole fibers are made by a process for drying a wet, coagulated polybenzoxazole (PBO) fiber including the steps of:(a) drying the fiber at a temperature of no more than 300.degree. C. under a tension of at least about 1 gram per denier (gpd) until it retains no more than about 120 weight percent residual moisture content;(b) further drying the fiber at a temperature of no more than 300.degree. C., either with or without tension, until it contains no more than about 20 percent residual moisture content; and(c) heat-treating the fiber at a temperature of at least about 300.degree. C. under tension.
