Fluorescent cellulose acetate, cellulose triacetate and polycaproamide fibr
es have been obtained using naphthalimide and naphthoylenbenzimidazole deri
vatives as luminophores. Determination of spectral characteristics and stab
ility of the fibres to W-radiation, wet processing and washing has shown th
e optimum luminophore concentration to be 0.4-0.6% based on polymer mass. (
