An alternative approach to the production of fluorescent colored fibres

Fluorescent cellulose acetate, cellulose triacetate and polycaproamide fibres have been obtained using naphthalimide and naphthoylenbenzimidazole derivatives as luminophores. Determination of spectral characteristics and stability of the fibres to UV-radiation, wet processing and washing has shown the optimum luminophore concentration to be 0.4¯0.6% based on polymer mass.
