Permeant degradation affects the brittleness, flexural fatigue, and ultimate tensile properties of polyester fibers more drastically than topochemical degradation. Topochemical degradation was obtained by hydrolysis with aqueous NaOH and permeant degradation by aminolysis with aqueous ethylamine. Treatment with aqueous sodium hydroxide appears to leave the polyester fiber surfaces more resistant to abrasion damage.
