Abstract
A process for incorporating a long persistent phosphor into a fabric material which occurs by firing a phosphor within a crucible, then grinding the resulting aggregate into a phosphor particulate of specified size, encapsulating the phosphor particulate within 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.
Claims20
A fibrous product comprising long persistent strontium based phosphor particulate encapsulated by a water-impervious silane coating binding to a surface of fiber host material through a covalent bond;
- and a chemical moiety extending from said coating and reactive with a complementary chemical moiety exposed on the fiber host material to form the covalent bond.
A fibrous product comprising long persistent strontium based phosphor particulate encapsulated by a water-impervious silane coating binding to a surface of fiber host material through a covalent bond;
- and a chemical moiety extending from said coating and reactive with a complementary chemical moiety exposed on the fiber host material to form the covalent bond, wherein said fiber host material is selected from the group consisting of:
- synthetic, natural and composite.
A fibrous product comprising long persistent strontium based phosphor particulate encapsulated by a water-impervious coating binding to a surface of fiber host material through a covalent bond further comprising a chemical moiety extending from said coating and reactive with a complementary chemical moiety exposed on the fiber host material to form the covalent bond wherein said coating is a silicon oxide.
A fibrous product comprising long persistent phosphor particulate encapsulated by a water-impervious organic chlorosilane coating bound to a surface of a natural fiber host material selected from the group consisting of cotton, wool, jute, linen, silk, and hemp.
