Long persistent phosphor incorporated within a fabric material

摘要

A process for incorporating a long persistent phosphor into a fabric material which occurs by firing a phosphor whithin a crucible, then grinding the resulting aggregate into a phosphor particulate of specified size, encapsulating the phosphor particulate witthin a water impervious coating material and then applying a specified ratio by weight of the encapsulated phosphor particulates into the fabric material. Further, a fibrous product is described incorporating encapsulated long persistent phosphor particles.
