WAVELENGTH-SHIFT COMPOSITE LIGHT-STORING POWDER, AND MANUFACTURING METHOD AND APPLICATION OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composite light-storing powder capable of obtaining a uniform dispersion effect, manufacturing light-storing fiber having multiple emission wavelengths through a spinning step and substantially enhancing the water washing resistance and heat resistance of the entire fiber, and a manufacturing method and application of the same.SOLUTION: The composite light-storing powder is obtained by: colliding an inorganic metal oxide with a light-storing raw material containing a rare earth element at a high speed under an extremely low temperature environment; causing fusion reaction of the inorganic metal oxide with the light-storing raw material on the surface thereof by the collision process; and causing a phenomenon that a photon is shifted by the variation of a crystal lattice structure to shift a wavelength. The composite light-storing powder can be easily chelated with the crosslinked structure of a thermoplastic polymer in a high temperature kneading step to obtain a uniform dispersion effect, manufacture light-storing fiber having multiple emission wavelengths through a spinning step and substantially enhance the water washing resistance and heat resistance of the entire fiber.
