Title: PHOTON MARKER SYSTEM FOR FIBER MATERIAL
Abstract:
Rare earth ceramic pigment luminescent nano-particle photon markers are mixed in specific proportions within cellulose slurry and extruded to form trace fiber strands. The trace fiber strands are processed into slivers and are blended with a base fiber or fibers at specific concentration levels. The number and proportion of different photon markers and their concentration levels within the yarn, thread, cloth, fabric, textile or garment generate specific photonic response signatures when examined under a spectrophotometer reader. Signatures may be assigned representing provenance, base fiber identification, base fiber concentration, the manufacturer, and/or other data throughout the manufacturing and supply chain of a finished product.
