Abstract
Flow agent particles, Aluminum Oxide C, are blended with metal oxide phosphor particles in an amount less than or equal to 2% by weight of the phosphor particles. The blended particles are finely sifted, through a 10 micron screen, in a sonic-sifting apparatus. The sifted particles are introduced into a carrier resin, thermoplastic polymers such as polyamide, polyester, and polypropylene, during the melt-stage of an extrusion and pelletizing process, to form pellets in an amount of less than or equal to 30% by weight of the polymer. The pellets are fed, via a volumetric color chip feeder, into a melt extrusion unit to form multi-filament phosphorescent textile yarn in an amount of less than or equal to 10% by volume of the polymer.
