Thermoplastic polymeric material in pelletized or chip form are initially coated with a wetting agent in a mixer, then a powdered phosphorescent pigment is added to the mixer and mixing continued until the pellets are substantially uniformly coated with phosphorescent pow- der. The coated polymeric material is then fed to an extruder where it is heated to form a melt and mixed to distribute the phosphorous material uniformly throughout the melt before being extruded to form phosphorescent textile fibers, filaments, yarns, tapes or fibrillated films having highly uniform phosphorescent properties.
