FIELD: paper making. SUBSTANCE: polyamide fibers with red fluorescence are prepared through depositing chelate complex of europium or samarium from organic solvent onto surface of initial fibers. Then, photoinitiator - benzoine methyl ester is inoculated on fibers followed by UV-initiated polymerization on fiber surface of acrylic acid ester oligomer in hexamethyleneteramine water-ammonia solution. EFFECT: improved procedure.
