FIELD: chemistry.
SUBSTANCE: fibre has a side-by-side structure and is moulded from a melt of one thermoplastic polymer containing two polymer-soluble dyes of the visible spectrum or luminescing in UV or IR light. The fibre is characterized by the criterion of tortuosity (CT) within the limits of 1.007-1.209. The concentration of each dye in the fibre is 0.1-0.9 wt %. The dyes contained in the fibre are selected for calculating the difference in the yield point values of the moulding melt containing the first dye and the yield point of the moulding melt containing the second dye in the range of 0.9-39.1 g/10 min.
EFFECT: increased degree of the paper protection.
