The application of the technology allows for introduction of the following modifying substances: ceramic oxides, metal oxides or their
mixtures, possibly containing additives of surfactants, carbon, possibly modified with silver, antibacterial agents, alkacimetric indicators,
and thermochromic dyes with nano- or supra-molecular dispersion. They are added to the cellulose, a solvent or a spinning solution at
quantities not exceeding 10% of the weight of the cellulose content.
