Polyamide fibers modified with photoluminescent pigments intended to protect the originality of fibers and fabric are composed of polyamide 6 in a proportion of from 99.70 to 99.99 % by weight and a labeling photoluminescent pigment in a proportion of from 0.01 to 0.30 % by weight. The labeling photoluminescent pigment can be of inorganic origin based on rare earth metals with a processing temperature of up to 450 °C or of organic origin based on the compound diphenylethylene bisbenzoxazole. Polyamidové vlákna modifikované fotoluminiscenčnými pigmentmi určené na ochranu originality vlákien a textílií sú zložené z polyamidu 6 v podiele od 99,70 do 99,99 % hmotn. a značkovacieho fotoluminiscenčného pigmentu v podiele od 0,01 do 0,30 % hmotn. Značkovací fotoluminiscenčný pigment môže byť anorganického pôvodu na báze kovov vzácnych zemín s teplotou spracovania do 450 °C alebo organického pôvodu na báze zlúčeniny difenyletylén bisbenzoxazolu.
